    Themioplastics castingsail
    The invention relates to a thermoplastic casting material for the production of articles, as well as the use of the cast matehal and a method for producing an article.
    Thermoplastic casting materials have been known for a long time and the manufacture of articles such as containers from such casting materials are well known in the art. The object of the present invention is to easily and inexpensively produce environmentally friendly bottles and cans as well as other articles such as packaging containers and containers for liquid bioprear products , Gias bottles have the disadvantage of the risk of breakage and plastics and bioplastics are undesirable for some applications, for example for aesthetic or ecological reasons.
    The object of the invention was to herzusfelien such containers at least for the most part of natural and non-toxic raw materials. Such containers rope also be produced by simple means and provide the required strength and safe disposal options.
    The thermoplastic casting material according to the invention is characterized in that the casting material contains a binder which is flowable in heat and solid at ambient temperature and at least one additive which does not melt at the melting temperature of the binder
    Further features of the invention can be taken from the claims and the following description.
    Preferably, the binder consists of one or more waxes, such as plant wax, animal wax, paraffin wax, montan wax or sterol. The waxes can also be provided mixed.
    When using waxes it has been found that they do not have the necessary strength. According to the invention, it has surprisingly been found that the strength can be increased considerably by adding an additive. In particular, these additives are fibrous materials and, in addition, in a further development of the application also fillers.
    The fibers are advantageously selected from the following group: natural fibers, vegetable fibers, wool, hair, silks, mineral fibers of geological origin chemical fibers of natural polymers such as viscose, modal, lyocell, cupro, acetate, acetate, gum, vegetable egg whites, animal protein, starch , Glucose, alginate, chitosan - synthetic fibers of synthetic polymers such as polyester, polyamide, aramid fibers of industrially produced inorganic fibers such as glass, carbon, ceramic, metal - textile fibers - paper fibers ~ Recyciaifasem.
    The fibers may vary in length. The fiber length is preferably less than 10 mm, more preferably less than 2 mm, in particular between 0.1 and 1 mm,
    The fillers are preferably selected from the following group of powdered materials, singly and as a mixture, such as annallne, basalt, pumice, dolomite, glass, garnet, granite, wood ash, kaolin powder, bone ash, marble, meerschaum, whey protein, quartz. Chamotte, whiting, silk protein, silica, talc, volcanic ash,
    Further features include the Gussmaiehai up to 30% by weight of pulp, Furthermore, the Gussmateriaf can contain up to BO wt .-% filler. The casting material may preferably contain up to 75% by weight of filler and up to 25% by weight of fibrous material, but together never more than 80% by weight, based on the total weight of the casting material. Particularly preferred is the wax carnauba wax,
    The Gussmatenal can be used in particular for the production of containers. In these containers, the liquids or puiver- or neselförmigen substances, such as, detergents. Perfumes etc, filled and also sealed with the Gussmatenal. In this case, the closure can be carried out in the absence of air, by pouring the Gussmatenal in liquid or viscous layer over the opening of the filled container or placed over it. By displacing the air, the shutter solidifies until it is opened again.
    The manufacturing methods for objects such as containers are removable from the known technology. For example, the Gussmatenal be poured in liquid form into a corresponding mold and after a certain cooling time any liquid material still be poured out, so that a container is formed. When falling below the melting temperature, a solidification point is reached by cooling, in which the mold can be opened and the object can be removed.
    When wax mixtures according to the invention are applied to e.g. 90 to 1ÖCFC are heated, the Gussmatenal is liquid. When cooled to, for example, 50 to 60X, the material is stiff enough to initiate the de-bonding process. The hardness of the manufactured article and its strength can be determined by the choice of aggregates and their weight content in the casting. The fibrous materials, especially in combination with fillers, e.g. Whiting or kaolin containers with high breaking strength
    A particular advantage of the containers or objects from the Gussmatenal according to the invention consists in the pleasant feel, since the surface feels slightly waxy and pleasant, since natural waxes are biodegraded, the objects can be easily disposed of, since they are ecologically safe.
    Below are examples of Gussmatenal, which are not limiting:
    Production of a vessel in the caster method Gussmatenal: 31% by weight of carnauba wax 65% by weight of calcium carbonate 4% by weight of cellulose fibers
    The casting material is heated until it is low viscosity and then poured into the mold. After a sufficient time, depending on the thermal conductivity of the mold ~~, the still liquid part of the casting material is poured out, the mold is opened and the hidded vessel is removed.
    The contents of the ingredients are broadly known, for example 25 ~ 35% by weight of carnauba wax, 60 ~ 70% by weight of calcium carbonate, 3-7% by weight of cellulose fibers,
    Example 2
    Sealing of a vessel of Gussmatenal: 37% by weight of beeswax 60% by weight of cellulose acetate, 3% by weight of cellulose fibers
    The casting material is heated viscous and poured over the filling opening of the vessel after it has been previously filled with a filling material. Alternatively, a piastically soft plate can be formed from the casting compound, which is placed over the filling opening and pressed out.
    The proportions of the in-molds can vary widely, for example 35 ~ 40% by weight of beeswax, 55 ~ 65% by weight of calcium carbonate, 2 ~ 5% by weight of cellulose fibers.
