MIXTURE FOR PRODUCING FIRE-RESISTANT ANHYDROUS COMPOSITE MATERIAL AND ARTICLES Russian patent published in 2011 - IPC C04B35/18 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions of fire-resistant anhydrous composite materials meant for compacting, separating and sealing high-temperature assemblies and units for transporting high-temperature melts in metallurgical industry. The mixture for making fire-resistant anhydrous composite material and articles contains fire-resistant filler, an elastomer, complex carbonaceous material and an additive. The fire-resistant filler is fire-resistant high-alumina filler of the 0.25-0.063 mm and 0.063-0.001 mm fraction. The complex carbonaceous material is in different amounts based on the mass of high-carbon thermoplastic material, nanosize carbon, crystalline graphite and bitumen, and the additive consists of different amounts per mass of aluminium hydroxide Al(OH)₃ and magnesium carbonate MgCO₃, with the following ratio of components in wt %: fire-resistant high-alumina filler of the 0.25-0.063 mm fraction 32.0-62.0; fire-resistant high-alumina filler of the 0.063-0.001 mm fraction 28.0-48.0; elastomer 7.5-13.0; complex carbonaceous material 2.0-4.0; additive 0.5-3.0.

EFFECT: high strength and burning point of articles.
