METHOD FOR PRODUCTION OF VERMICULITE HEAT-INSULATING COMPOSITION

摘要

FIELD: construction. ^ SUBSTANCE: method for preparation of vermiculite heat-insulating composition includes mixing binder - portland cement with additives with dry components of filler - blown-out vermiculite and ground mineral fibre, besides binder is previously mixed with mixing water, then mixed with 25-30% of mixture of dry filler components, and in 20-30 minutes it is mixed with remaining part of dry filler components mix previously heated up to 80-85C in 5-10 minutes, and produced heat-insulating composition is maintained for 15-20 minutes before application onto protected surface. ^ EFFECT: increased adhesion of vermiculite heat-insulating coating with protected surface and provision of its integrity in process of operation at exposure to high temperature. ^ 1 cl, 2 tbl
