Abstract

The invention discloses a high-efficiency waterproof coating. The high-efficiency waterproof coating is prepared from 42-55 parts by mass of an acrylic elastic emulsion, 11-13 parts by mass of polyvinyl alcohol, 6-8 parts by mass of hydroxypropyl methylcellulose, 12-16 parts by mass of polyurethane, 8-12 parts by mass of talc powder, 12-14 parts by mass of titanium dioxide, 13-17 parts by mass oftoluene, and 50-60 parts of water. The high-efficiency waterproof coating is non-toxic and environmentally friendly, has strong anti-aging ability, prevents falling-off and cracking caused by wind, rain and sun, has good waterproof performances, realizes a low cost and is not easy to fall off.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-efficiency waterproof coating. Background technique [0002] The enclosure structure of the building should prevent the infiltration of rainwater, snow water and groundwater; it should prevent the erosion of moisture, steam and other harmful gases and liquids in the air; the separation structure should prevent the seepage of water supply and drainage. Materials that leak and corrode are collectively referred to as waterproofing materials. The waterproof film formed after the waterproof coating is cured has good anti-penetration, leakage and erosion effects on the building. However, after a period of use, the waterproof coating often falls off, cracks and loses waterproof due to wind, water, sun and rain. Function. Contents of the invention [0003] In order to solve the above existing problems, the present invention provides a non-toxic and environmentally f...
