Polymer cement waterproof paint

Abstract

The invention discloses polymer cement waterproof paint which consists of the following components in percent by weight: 50-60% of a vinyl acetate-ethylene copolymer emulsion, 20-30% of silicate cement, 14-16% of quartz powder, 2-10% of quartz sand, 0.25-0.75% of wood fiber and 0.05-0.15% of defoaming powder. The polymer cement waterproof paint disclosed by the invention is cement-based waterproof paint which takes the high molecular ethylene copolymer emulsion as a main film forming matter and various fillers such as cement as the main components. Slurry and powder are mixed to react chemically to form a tough elastic waterproof membrane. The membrane has good adhesion to concrete and mortar and can be compactly and firmly combined with concrete and mortar permanently so as to prevent water permeation. The paint has excellent initial adhesion and mechanical stability, higher viscosity and consistence, high coating ductility and good elasticity, and can be used for construction on moist basic levels.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to a polymer cement waterproof coating, which belongs to the technical field of building materials. Background technique [0002] It is necessary to form a film on the surface of the building through the volatilization of solvent or water or the chemical reaction of the two components, so as to isolate the surface of the building from water, so as to play the role of waterproof and sealing. These viscous liquids for painting Called waterproof coating. In some military projects, mechanical pits, tunnels, swimming pools, pools, basements, water supply pipe drainage and irrigation sluices pasted with tiles, and concrete structures such as roofs, toilets, balconies, and pipe joints, although they are coated with conventional waterproof coatings, Once cracks appear in the concrete, water seepage still occurs in the cracks. The reason is that the existing common waterproof coatings have poor initi...
