Modified silicon waterproof coating

The invention discloses a modified silicon waterproof coating, which comprises the following raw materials by weight: 60-80 parts of organic silicon rubber, 12-16 parts of a curing agent, 30-50 partsof silica gel, 8-12 parts of a coupling agent, 16-20 parts of nano-silica, 18-22 parts of nano-alumina, 7-11 parts of pigment and filler, 4-8 parts of a film-forming assistant, 6-10 parts of a leveling agent, 35-55 parts of light calcium carbonate, 35-55 parts of talcum powder, 20-24 parts of an emulsifier and 12-16 parts of titanium dioxide. The modified silicon waterproof coating provided by theinvention has the characteristics of no toxicity, no odor, noninflammability, safety and reliability, and long service life, can still maintain performance at low temperature, is better in hydrophobicity, can form a rough surface needle-shaped structure on a surface, enables sewage and dirt not to remain, and has certain self-cleaning function. 本发明公开了一种改性硅防水涂料，包括以下重量份的原料：有机硅橡胶60-80份、固化剂12-16份、硅胶30-50份、偶联剂8-12份、纳米二氧化硅16-20
