    1527624 Building material J Z VERTH 22 Oct 1975 [5 Nov 1974] 43427/75 Heading C3N A building material in the form of a panel or strand is formed from a mixture comprising finely divided calcined magnesite, a wood filler consisting predominantly of wood chips, inactive diatomaceous earth, and an aqueous solution of magnesium chloride, characterized in that (a) the weight ratio of magnesium oxide to wool filler in said panel or strand is 1 ; 2.96- 1 : 4; (b) the weight ratio of magnesium oxide to magnesium chloride (calculated as anhydrous magnesium chloride) in said mixture is 3 : 1- 4 : 1; (c) the weight ratio of magnesium chloride (calculated as anhydrous magnesium chloride) to wood filler in said mixture is 1 : 9-1 : 12 and (d) the content of inactive diatomaceous earth in said mixture is 2-15% by weight of the wood filler. The mixture may also include an alkali metal silicate, talc, rock filler, or magnesium sulphate. The wood filler particles may have a length of 20 mm. at most. The particles may be oriented essentially parallel to a plane which is normal to the direction of the extrusion of the article and also normal to the plane of the major surfaces of the panel or strand. Alternatively, the wood filler particles are oriented essentially parallel to the plane of the major surfaces of the panel or strand. In one embodiment the building material is composed of a plurality of layers; the outer layers containing a more finely divided wood filler and having a weight ratio of magnesium oxide to mgnesium chloride of 2À8 : 1-3À2 : 1 and the inner layers containing a less finely divided wood filler and having a weight ratio of magnesium oxide to magnesium chloride of 3À8 : 1-4À2 : 1. In a process for producing the building material the wood filler is admixed with all the other components except magnesium chloride and water and to the resulting mixture is thereafter added an aqueous magnesium chloride solution.

    one
    The invention relates to building materials, namely the manufacture of xylolite products.
    Known xylolite material, including wood chips, ground caustic magnesite containing wt.% MDO, MDSE2, MgS04ll
    The disadvantage of it is low fire resistance.
    This material is closest to the invention in its technical essence and the effect achieved.
    The aim of the invention is to obtain a flame retardant material with reduced heat emission.
    The goal is achieved by the fact that xylolitic material, including wood chips, magnesite in water and water, contains magnesia in wood at a weight m ratio of MDO: MDCE, from 3: 1 to 4; 1 and additionally inert kieselgur, manna flour, with the following the ratio of components, wt.%:
    Wood chips 54-72
    Magnesian in a stranger24-36
    Inert Kieselguhr-10,8
    Flour miner 0,1-7,2
    Water2-15
    Wood chips are used up to a size of 20 mm.
    PRI me R. The xylolite material is prepared as follows.
    58% of wood chips with a particle length of not more than 20 mm with 1.7% inert kieselgur, 0.17% of mine flour and 20% of fine calcined magnesite are dry blended, and the mixture is impregnated with a solution containing 5% MCE and 15.17% by weight .ch, the water obtained lumpy mass is formed in the form of a plate and cured in a press at a pressure of 15-50 bar and a temperature of 120 ° C 220 ° C for 3-20 minutes.
    A plate made of xylolite material with a thickness of 19 N-SM and an area of 4.5 tested by fire at a temperature of 843 ° is not destroyed for 30 minutes, and on the side opposite to the flame, the temperature rises no more. Its appearance corresponds to the appearance of traditional dies with an artificial resin binder.
