DRY SCHUNGITE-BASED COMPOSITION TO PRODUCE MATERIALS WITH UNIQUE COMBINATION OF PROPERTIES (SCHUNGILITE)

摘要

FIELD: construction.;SUBSTANCE: invention may be used to manufacture wear-resistant waterproof heating coatings, such as self-levelling warm non-burn cast-in-place floors in residential and production buildings, sports, shopping, exhibition rooms, iced sites, staircase steps, ramps, to manufacture aesthetic cast radio-screening products and structures, and is also recommended as a finishing material in healthcare institutions. A dry schungite-based composition for production of materials with a unique combination of properties (Schungilite) includes, wt %: caustic magnesite powder - 20.3-32.2; caustic brucite powder - 8.7-13.8; polycarboxylate powder - 0.5-1.5; powder of vinyl acetate/ethylene copolymer - 0.5-3.0; powder of zinc stearate - 0.6-1.8; polydispersed schungite - balance.;EFFECT: increased coefficient of water resistance, crack resistance, strength, reduced water absorption, abradability, higher adhesion to various surfaces.;1 tbl
