Abstract

The invention discloses a micro-expanding inorganic thermal insulation mortar. The micro-expanding inorganic thermal insulation mortar comprises the following raw materials in parts by weight: 700-800 parts of ordinary portland cement, 100-200 parts of desulfurized fly ash, 30-40 parts of anhydrous calcium chloride, 0.6-1 part of butyl tin tris-2-ethylexanoate, 4-6 parts of teflon fiber, 1-2 parts of silylation powder SHP-50, 1-2 parts of polyacrylamide, 6-10 parts of sodium doodecyl benzene sulfonate, 3-5 parts of poly-4-methyl-1-pentene, 20-30 parts of a performance additive, and a proper amount of water. The thermal insulation mortar has the advantages that the combustibility is low, the fire-proof level is high, and volatile gas and toxic or harmful gas can not be emitted at high temperature; excellent breaking strength and crack resistance are achieved.
