Frost-crack-resistant, waterproof and weather-proof building coating and preparation method thereof

Abstract

The invention discloses a frost-crack-resistant, waterproof and weather-proof building coating and a preparation method thereof. The building coating comprises the following components in parts by mass: 15-25 parts of polyvinyl alcohol, 15-25 parts of polyacrylate emulsion, 10-20 parts of silica sol, 10-20 parts of polyamide, 10-20 parts of quick lime, 10-20 parts of castor oil, 10-20 parts of potassium oxide, 10-20 parts of zinc oxide, 5-15 parts of aluminum oxide, 5-15 parts of polyvinyl acetate, 5-15 parts of methyl methacrylate, 10-20 parts of phenolic resin, 5-15 parts of ground limestone, 5-15 parts of bentonite, 15-25 parts of nano-silica, 15-25 parts of poly(vinylidene fluoride) resin, 15-25 parts of acrylic resin, 10-20 parts of diethylene glycol monobutyl ether, 10-20 parts of xylene, 5-15 parts of saturated hydroxyl terminated polyester resin, 3-5 parts of an antifoaming agent, 3-5 parts of a plasticizer, 3-5 parts of a dispersing agent, 3-5 parts of a fast dry agent, 3-5 parts of a coalescing agent, 3-5 parts of additives and 25-45 parts of deionized water. The building coating disclosed by the invention has the advantage that the waterproof effect and the like are improved, and can be constructed on base planes of multiple humid or dry materials; the building coating is excellent in waterproof performance, non-toxic and harmless, and meets the actual application requirement.

Description

technical field [0001] The invention relates to a frost-cracking-resistant, waterproof and weather-resistant architectural paint and a preparation method thereof, belonging to the technical field of paint and preparation technology. Background technique [0002] Architectural coatings are a kind of coating products used for house decoration. Some buildings have special requirements for mildew resistance, fire prevention, heat insulation, and corrosion resistance. Some buildings have special requirements for waterproof, antifreeze, and crack resistance. Decorations have special requests. The living improvement function is mainly for indoor coating, which is the function that helps to improve the living environment, such as sound insulation, sound absorption, anti-condensation, etc. A general term for a class of liquid or solid materials that can form a solid coating film with protective decoration or special properties (such as insulation, anti-corrosion, signs, etc.) when a...

Problems solved by technology

[0003] At present, this kind of paint in the prior art has great harm to the human body and the environment, and it is easy to cause phenomena such as aging, cracking, deformation, breaking, and delamination. For places with complex shapes, construction is difficult, and for leakage , the quality is difficult to guarantee, and every few years, it will cost a lot of money and labor for repairs, which makes the cost continue to rise and affects the service life of the building
