Thick-painted cement-based waterproof coating
The invention discloses a thick-painted cement-based waterproof coating, which consists of liquid materials and powder materials, wherein the liquid materials and the powder materials are made from raw materials with parts by weight: the liquid materials comprise high polymer emulsion 80%-90%, water 10%-20% and auxiliaries 3%-10%, the powder materials comprise cement 30%-50%, graded sands 20%-40%, glass beads 10%-30%, precipitated barium sulphate 10%-30% and auxiliaries 3%-10%. The thick-painted cement-based waterproof coating can achieve a thickness which is required by standard construction through once thick-painted construction in the non-cracking condition, saves time and labor, and greatly saves cost for building construction. Experimental results show, the thick-painted cement-based waterproof coating uses roll coating, brush coating and roll coating modes to construct, can achieve 1.5mm-2.0mm construction thickness, can achieve above 3.5MPa bonding strength, can achieve above 250% elongation at break, and does not have unhealthy phenomena of cracking, sagging and slipping and the like.
