Composite environment-friendly waterproof dry-mixed mortar and preparation method thereof
The invention provides composite environment-friendly waterproof dry-mixed mortar and a preparation method thereof. The composite environment-friendly waterproof dry-mixed mortar is prepared from cement, sand, modified polymer latex powder, admixtures and chemical additives, wherein the sand is composed of fine sand and kaolin tailing sand, the modified polymer latex powder is siloxane-styrene-acrylate copolymer latex powder, the admixtures comprise high-calcium fly ash, steel slag micropowder and modified chrysotile fibers, and the chemical additives comprise modified waterproof adhesive powder, dialkyl polysiloxane, methacrylic acid, hydroxyethyl methyl cellulose and 2-acrylamide sodium 2-methallyl sulfonate. In this way, the composite environment-friendly waterproof dry-mixed mortar is high in compressive strength, good in waterproof performance, high in cracking resistance and shrinkage resistance and low in cost.
