UNIVERSAL GLUING MASTIC (VARIANTS) Russian patent published in 2002 - IPC

FIELD: building materials. SUBSTANCE: invention claims the composition containing water glass as a base, powdered quartz and microtalc as a mineral filling agent and modifying addition. For making the moisture-resistant composition it has polyvinyl acetate emulsion, carboxymethylcellulose and varnish as a base additionally. It has Portland cement as a mineral filling agent additionally and modifying addition has dibutyl phthalate as a plasticizer. For making the moisture-resistant composition it has polyvinyl acetate emulsion and/or casein glue as a base additionally and it has chalk as a mineral filling agent and drying oil and plasticizer dibutyl phthalate as a modifying addition. For making the heat-resistant composition it has powdered limestone and asbestos as a mineral filling agent additionally and plasticizer dibutyl phthalate as a modifying addition additionally. Each universal mastic can contain inorganic pigments: Fe₂O₃, CoO, Co₂O₃, Cr₂O₃, PbO, TiO₂ as coloring components. The combination of components in definite ratio ensures to obtain gluing mastics with high technological indices (detachment strength value, hardening time) and the broad assortment of consumers' properties (water resistance, moisture resistance, heat resistance, resistance to cold, color assortment). Invention can be used in chemical industry and industry of building materials. EFFECT: improved quality and properties of gluing mastic. 6 cl, 1 tbl
