    The invention relates to a raw material feed for a slurry for the production of continuous mineral fibers and to a process for the production of continuous mineral fibers from a melt and to the use of the raw material feed according to the invention.
    Mineral fibers are fibers of inorganic raw materials. Mineral fibers also include basalt fibers, which are industrially produced, thin rock fibers, in particular basalt fibers.
    Generally speaking, although mineral fibers have a similar appearance to glass fibers, their chemical composition is significantly different from that of the glass fibers due to the high iron, calcium and magnesium content and relatively low levels of silica and aluminum.
    However, it is important to distinguish between basalt wool and continuous basalt fiber. Endlosbasaltfasern are harmless to health. To the best of our knowledge, it is believed that fibers of length> 5 pm, diameter <3 pm and length / thickness ratio> 3 (WHO fibers) in humans may possibly induce lung tumors after inhalation. For thicker fibers (diameter> 3 pm), such a risk is not expected because these thicker fibers are deposited on the nose during inhalation and therefore can not enter the lungs.
    Industrial applications of mineral fibers are numerous and diverse. The physical properties and thus the fields of application are similar to those of glass fiber. Basaitfasern are used as reinforcing fibers in fiber-plastic composites, such as lightweight construction in cars and commercial vehicles, in space, defense and aircraft industry, etc. or as heat protection material. They are suitable for use in many high temperature applications.

    Basalt fiber, more precisely, the continuous basalt fiber (EBF), is produced in a smelting process. This basalt rock is refined with defined chemical properties in a complex melting process to basalt fibers. They are made from a liquid Basaichmelze at about 1400 ° C. The composition of the melt influences the physical and chemical properties of the basalt fiber.
    It is generally known to use rocks, such as basalt, dolomite, limestone or metallurgical slag for the production of mineral fibers. However, basalts are not well suited for melting in cupola or electric furnace. They soften at relatively low melting temperature, but are quite viscous with further increase in temperature over a large temperature interval. As a result, a continuous melting process and a uniform outflow of the melt from the melting unit are not guaranteed. By adding basic aggregates such as limestone or dolomite or foamed blast furnace slag to the basalt, a uniform melt flow is achieved, but at the same time a short softening interval. This has a detrimental effect on subsequent fiber production both on the fiber quality and on the fiber yield.
    From DD 223 435 A1 melted material of 75% to 45% basalt and 25% to 55% diabase, for the production of mineral fibers from molten rock is known. Up to 10% blast furnace slag or limestone can be added to the melted material. Preliminary work to homogenize or garnish the ingredients prior to their use in the melter is not required.
    The object of the present invention is to provide a raw material feed for a melt for the production of endless mineral fibers, wherein favorable properties of the melt are to be achieved in order to improve the production of endless mineral fibers of high fiber quality, in particular endless basalt fibers.
    The object of the invention is in each case independent by a raw material embroidery comprising 30% to 70% basalt and / or diabase, 10% to 40% quartz component, in particular quartz sand, and 5% to 30% slag, in particular blast furnace slag, and a process for producing endless Mineral fibers from a melt consisting of raw material comprising 30% to 70% basalt and / or diabase, S% to 40% quartz N2010 / 11900 22/12 2010 MI 15:48 tSE / EM NR 8049] @ 006 25 15:51 : 42 22-12-2010 7/24 • * * «* * * * * 4 · • * t« * * · «* * *« 4

    Advantageously, it turns out that the use of basalt or diabase as the main component of the raw material feed a substance is used, which is inexhaustible due to the extremely large occurrence and ongoing genesis by volcanic activity as a raw material. The same applies to the use of quartz sand - the worldwide quartz sand reserves are given as virtually unlimited. The use of silica sand achieves the desired silica content of the continuous basalt fiber required as a network former.
    Slag in metallurgy refers to a glassy or crystalline solidified enamel residue of non-metallic nature. They consist essentially of calcium silicate and silica glass. The glass content is usually &gt; 75%. Slag, in particular blast furnace slag, is advantageously used to obtain the silicon dioxide shell and thus the required proportion as a network former in the melt or in the mineral fiber. By adding the raw materials according to the invention for the production of mineral fibers dfe cost of production can be kept low compared to the addition of the required substances in pure form.
    By using the described raw materials such as basalt or diabase, quartz sand and blast furnace slag, the amount of other additives that can increase the costs of producing the mineral fibers, especially Endlosbasaltfasem on the one hand and on the other hand can be polluting, avoided or kept as low as possible.
    Basalt fibers from the raw materials of the invention contain no toxic and / or hazardous components. The continuous filaments of the present invention are directional fibers having a mean fiber diameter &gt; 9 pm and, due to the small standard deviation of about 10%, contain no fibers mR of diameter &lt; 3 pm. They also do not splinter longitudinally (fibrillate), resulting in no fiber fragments that can penetrate the alveoli of the lung. According to TRGS 521, particles with lengths of more than 5 μm, diameter of less than 3 μm and length to diameter ratios of more than 3: 1 are considered as fiber dust. The basalt fiber is so thick that it is not In

The half-life, which is the time it takes to break down half of an in-body material, is significantly shorter than 40 days for the basalt fiber, thus eliminating classification into the carcinogenic substances.
    The inventive composition of the raw material for the melt for producing continuous mineral fibers comprising 45% to 55% basalt rock and / or diabase, 19% to 34% quartz sand and 7% to 13% slag, in particular blast furnace slag, a high fiber yield with good fiber quality achieved. Thus, constant coil sizes can be produced without filament breakage.
    The Endfosbasaltfaser produced from the raw materials according to the invention is characterized in particular by high temperature resistance, high tear strength, high chemical and alkaline resistance, very good insulating and elongation properties and good recyclability.
    Finer fibers stand next to higher specific surface for higher specific strength. Due to the property profile and above all the higher modulus of elasticity, the higher chemical resistance and the higher temperature stability, these endiosbased fibers have clear advantages over E-glass fibers. The basalt fibers can compete with the glass fiber. Replacement by basalt fibers is particularly suitable in those areas in which the combination of higher modulus of elasticity, extended temperature range and improved chemical stability, especially in the alkaline range, are of importance. The basalt fiber is established in niches where glass fibers can only be used to a limited extent, but the use of very expensive carbon fibers is not economically justifiable. The Endlosbasaltfasern can be used as a glass fiber substitute, e.g. used as a heat and scraping filler, etc. As the continuous basalt fiber is also very heat resistant, it can also be used as a substitute for the asbestos fiber. There is also concrete with continuous basalt fibers, which can be used instead of reinforced concrete.
    The material recycling of basalt fibers is possible without any problems, as with glass. Glass already has a recycling rate of over 80%. From a technical point of view, a higher recycling rate can be achieved for basalt fibers as they are derived from natural resources.

    The advantage over conventional fibers Is also that Endlosbasaltfasem recyc-lebar are, because they are won from natural raw materials.
    It is advantageous that 2% to 20%, in particular 5% to 12%, of clay, in particular clay minerals and admixtures, are included, because clays and their secondary products convert to harder and stronger minerals on heating. In addition, clay serves as a source of silicon and aluminum.
    Boron compounds, in particular boric acid and / or derivatives thereof, in particular salts, are used in an amount selected from a range with a lower limit of 1%, in particular 3%, and an upper limit of 10%, preferably 5%, with boron compounds as Fluxes are used. In addition, they improve the corrosion resistance of mineral fibers. Boron compounds, in particular boric acid or its derivatives, can lower the thermal expansion coefficient and thus improve the thermal shock resistance of the continuous basalt fiber, such as e.g. in reinforcing fibers.
    Iron compounds are used in an amount selected from a range with a lower limit of 0.1%, in particular 0.5%, and an upper limit of 10%, preferably 1%, the iron compounds serving as network converters and thus the structure and change the properties of the fiber. Network converters are installed in the framework formed by the network former. For ordinary utility glass - lime-alkali glass - these are sodium or potassium oxide and calcium oxide. These network converters tear up the network structure. This bond of the bridge oxygen are broken in the silica tetrahedra. Instead of the atomic bond with the silicon, the oxygen enters into an ionic bond with an alkatiatome.
    Calcium oxide is used in an amount selected from a range with a lower limit of 1%, in particular 2%, and an upper limit of 10%, preferably 4%, for the melt, with calcium oxide being able to serve as a network wall. In the moderate addition according to the invention, CaO increases the hardness and chemical resistance, in particular the alkali resistance, of the mineral fiber produced from the melt, in particular continuous basalt fiber. Ca compositions are deposited on the basalt fiber surface.
    Fluorene carriers, such as fluorspar, are selected in an amount ranging from a lower limit of 1%, more preferably 2%, to an upper limit of 10%, pre-N2010 / 11900 22/12 2010 MI 15:48 [SE / EM NO 8049] @ 009 25 15:52:33 22-12-2010 10/24 -6%, preferably 3%, with the addition of fluorspar as a flux. This additive facilitates the melting process and the handling of the molten substances. In addition, it reduces the melting temperature and the viscosity of the melt.
    Furthermore, minerals and raw materials can also be selected from a group comprising metal compounds, such as manganese, titanium, copper, aluminum, cobalt compounds, alkali compounds, sodium, potassium compounds, alkaline earth compounds, such as magnesium or magnesium compounds. Barium compounds, kaolin, soda, are added to the raw material feed, whereby endless basalt fibers can be produced according to the desired properties.
    In one development of the invention, raw material is at least partially formed as regrind and / or as a shaped body which consists of particles, in particular regrind, basalt and / or diabase, at least one quartz component, in particular quartz sand and slag, in particular blast furnace slag, to form the melt which facilitates the melting process by providing homogeneous conditions in the furnace, thus improving both mineral fiber quality and increasing mineral fiber yield.
    Particularly advantageous are moldings having a size with an upper limit of 100 mm, because thereby the energy input for melting the moldings can be kept low in the furnace without simultaneously affecting the melting properties negative.
    Advantageous in the use of the inventive method for producing continuous mineral fibers from a melt of raw material comprising 30% to 70% basalt and / or diabase, 10% to 40% quartz sand and 5% to 30% slag, especially blast furnace slag, proves that All working and processing operations with basalt products comply with Kyoto-2012 regulations. Neither when heated, toxic gases, foams or vapors nor other products or wastes polluting people or the environment.
    It also proves to be advantageous that the raw material is at least partially used as shaped bodies, which are formed from particles of basalt and / or diabase and at least quartz sand and slag, for forming the melt. Fiber produced by the present process is not expected to produce fiber dust, so neither in production nor during processing, nor in use, nor in production, processing or use 15: S2: 50 22-12-2010 11/24 -7 even if these fibers are disposed of, a health risk for the persons involved is to be expected. For certain applications, basalt fibers made by the process of the present invention can also be used as a substitute for asbestos fibers.

    The present invention describes raw material used for the production of the melt for further processing into mineral fibers, in particular endless basalt fibers. In the context of the invention is MMMF (man made mineral fibers) - ie synthetically produced mineral fibers.
    Mineral fibers can therefore be produced inexpensively. They can be made from a variety of materials, including igneous rock and basalt, from slag produced by blast furnaces used to make steel and other metals, and from waste products of the phosphate industry.
    As basalt can u.a. Rock from the basalt deposits Radtpaß, Klöch, Oberhaag, Kim, Solosnica, Losonec, Kamenec, Zelesice, Zbraslav, Belice, Okucani, Rakovac, ceramides, etc. are used.
    Preferably, the main constituent of the melt is formed by basalt. The composition of the melt influences the chemical and physical properties of the basalt fiber, in particular by the iron content.
    By using quartz components, in particular quartz sand, in combination with slag, in particular blast furnace slag, for producing the melt, it is possible to introduce the required content of SiO 2 into the melt. Rather, it is thereby also possible to favorably influence the melting behavior of the melt and then to enable an amorphous solidification of the melt. For the invention quartz sand to be used favorably consists of more than 95% SiO 2.
    The addition of other substances can improve the yield and quality of the continuous mineral fiber.
    Clay, in particular clay minerals and admixtures and secondary products cause a higher strength of the endless mineral fiber produced from the raw materials according to the invention. Clay serves as a source for SI02 and AI203 and optionally Fe203. Thus, typical clays to be used for the invention have between 50 to 90% SiO 2 .10 to 30% Al 2 O 3 and up to 20% FejCb in addition to small amounts of CaO, MgO, K 2 O, TiO 2.
    Fluxes, such as fluorine compounds, in particular fluorspar and / or boron compounds, such as boric acid, influence the viscosity of the melt, and thus the N2010 / 11900 22/12 2010 MI 15: 4a [SE / EM NR S049J 12 25 1S: 53: 22 22 12-2010 13/24 - 9 -
    Production parameters are optimized for the subsequent drawing or spinning process,
    Calcium oxide and iron compounds are used as network converters. In addition, the iron content also allows the polyvalent properties of the iron to be used selectively, for example the optical properties, in particular the infrared absorption, mechanical properties, such as tensile strength. Binding properties to plastics, etc. Iron compounds are also added to improve the flow properties of the melt or for the color.
    Feldspar also serves as SiOa and A! Z03 source. Typical feldspars to be used for the invention have an SiO 2 content of over 60% and an Al 2 O 3 content of more than 15%. Kaolin is also used as the SiO 2 and Al 2 O 3 source.
    By using the raw materials in moldings, a uniform melt is formed with a viscosity from which endless mineral fibers can be drawn or spun.
    The slag used is ground blast-furnace slag with the main components SI02l CaO, A! 203, and MgO. A composition of an example of a blast furnace slag to be used for the invention is given below: 37% SiO 2, 36.3% CaO, 8.4% MgO, 10.6% Al 2 O 3, 0.4% Fe 2 O 3) 4.1% NaaO, 0 , 1% P 2 O 5, 1.4% K 2 O, 0.5% TiO 2, 1.3% MnO.
    In a further development, synthetic minerals and raw materials selected from a group comprising iron compounds, manganese compounds, titanium compounds, boron compounds, etc. can also be added in order to optimize production parameters or to influence the properties of the continuous basal fiber accordingly.
    The exact chemical composition of the basalt fiber depends on the composition of the melt and thus on the raw materials used to form the melt. Basaltx basalt fibers known from the prior art have the following composition in mass percent: 52% SiO 2 .17% AL 2 O 3 &gt; 9% CaO, 5%, MgO and 17% other ingredients.
    By using the raw materials for forming the melt according to the invention, it is possible to produce continuous mineral fibers with the following compositions in% by weight: N2010 / 11900 22 / J2 2010 Ml 15:48 [SE / EM NE 8049] © 013 25 15:53 : 37 22-12-2010 14/24 - 10

    Group 1 mineral fibers can be made, for example, by the use of basalt in Klöch. Mineral fibers of group 2 have an increased SiO 2 content. Basalt fibers of group 3 have an increased proportion of Al2Oa. For Group 4 fibers, diabase is used as the raw material and andesite for Group 5 fibers.
    In particular, continuous mineral fibers, in particular continuous basalt fibers, can be produced from the raw materials according to the invention by means of X-ray diffraction analysis (slight deviations of 100% in total are possible due to measurement inaccuracies, loss on ignition, etc.):
