Abstract

The invention discloses a special roof-spraying waterproof material. The special roof-spraying waterproof material is prepared from, by weight, 400-550 parts of emulsion, 80-120 parts of silica powder, 300-400 parts of calcite powder, 40-60 parts of rutile titanium dioxide, 30-50 parts of deionized water, 2-4 parts of dispersing agent, 2-4 parts of defoaming agent, 1.5-2.5 parts of preservative, 0.8-1.2 parts of ultraviolet light absorber and 0.8-1.2 parts of anti-aging agent. A preparing method of the special roof-spraying waterproof material includes the steps that the silica powder, the calcite powder, the rutile titanium dioxide, the deionized water, the dispersing agent, the defoaming agent, the preservative, the ultraviolet light absorber and the anti-aging agent are stirred to be even at a high speed, the emulsion is added at a low speed, the mixture is stirred to be even, and the special roof-spraying waterproof material is obtained through filtering. The emulsion is acrylic emulsion or a mixture of acrylic emulsion and aliphatic-series waterborne polyurethane emulsion or a mixture of acrylic emulsion and waterborne epoxy resin emulsion. The special roof-spraying waterproof material is mainly used for water resisting of roofs.

Description

Technical field [0001] The invention belongs to the field of building materials, and specifically relates to a special waterproof material for sprayed roofs. Background technique [0002] With the development of China's construction industry, the building waterproofing market is getting bigger and bigger. Traditional roofing waterproofing materials are mainly modified bitumen waterproofing membranes for hot-melt construction. This material is prone to aging and brittleness when heated, and it is hotter than cement roofing and metal roofing. Cold shrinkage is inconsistent, easy to peel, and is greatly affected by construction. The protection period is short. It is easy to leak after 5 years. It is flammable and not environmentally friendly. Moreover, the waterproof materials currently sprayed in China are quick-setting rubber waterproof coatings and polyurethane waterproof coatings. Waterproof coatings are rubber and polyurethane, which have poor UV resistance and aging resistance...
