Thermal insulation high-elasticity waterproof paint and preparation method thereof

Abstract

The invention discloses a thermal insulation high-elasticity waterproof paint which is characterized by being prepared from the following raw materials in parts by weight: 20-45 parts of organosilicon rubber emulsion, 6-8 parts of organosilicon waterproof agent, 2-5 parts of graphene prefabricated dispersion, 0.1-0.6 part of emulsion type antifoaming agent, 0.1-0.6 part of sodium carboxymethylcellulose, 2-4 parts of triphenyl phosphate, 6-9 parts of coumarone resin emulsion, 3-6 parts of attapulgite powder, 4-6 parts of perlite powder, 1-2 parts of ultraviolet absorber, 4-6 parts of fly ash, 7-9 parts of styrene-acrylic emulsion and 3-4 parts of linoleic acid. The waterproof paint disclosed by the invention has unique waterproof property, high elasticity and integrity; the film is continuous without any joint; the cured paint film has moderate hardness and good elasticity and is not broken easily; the added graphene has good performance in corrosion resistance, thermal insulation and salt mist resistance; the added perlite powder and fly ash are cheap and realize a good heat insulation effect; and the paint disclosed by the invention has the advantages of easiness in construction, short construction time, safety and environmental protection, no toxicity or odor, low cost and good application prospect.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a heat-insulating high-elasticity waterproof coating and a preparation method thereof. Background technique [0002] Waterproof coating refers to the coating used to prevent water intrusion and leakage. The waterproof film formed after curing of the waterproof coating has certain extensibility, elasticity, crack resistance, impermeability and weather resistance, which can play a role in waterproofing and waterproofing. Infiltration and protection, waterproof coatings have good temperature adaptability, easy operation, and easy repair and maintenance. There are two types of waterproof materials on the market: one is polyurethane waterproof coatings, which are generally made of polyurethane and coal. Tar is made as a raw material, and the tar gas it volatilizes is highly toxic and not easy to remove, so it was banned in China in 2000. The polyurethane waterproof coatin...

[0002] Waterproof coating refers to the coating used to prevent water intrusion and leakage. Waterproof, anti-seepage and weather resistance, can play a waterproof, anti-seepage and protective role, waterproof coating has good temperature adaptability, easy to operate, easy to repair and maintain, there are two types of waterproof materials on the market: one is polyurethane Waterproof coatings, this kind of material is generally made of polyurethane and coal tar as raw materials, the tar gas it volatilizes is highly toxic and not easy to remove, so it was banned in China in 2000, and the polymer that is still on sale Urethane waterproof coating uses asphalt instead of coal tar as raw material, but when using this kind of coating, it is generally diluted with organic solvents such as benzene, so it is also toxic; at the same time, it is inconvenient to construct, the construction period is short, and the environmental protection is relatively relatively Difference
