Anti-freezing external wall coating material

Abstract

The invention relates to an anti-freezing external wall coating material, which is prepared from the following raw materials by weight: 15-19 parts of a polyester resin, 2-6 parts of triethanolamine, 4-9 parts of ultra-fine barium, 1-3 parts of graphene, 3-8 parts of an acidic aqueous silica gel, 4-6 parts of nanometer alumina, 6-10 parts of polyurethane, 2.5-4 parts of a film-forming auxiliary agent, 3.5-6 parts of an ultraviolet absorber, 7-9 parts of a solidification glue, 1-2 parts of silicone oil, 4.5-7 parts of kaolin, 4-5.5 parts of acrylonitrile, 4.5-7 parts of grinding calcite carbonate, 11-16 parts of pure acrylic emulsion, and 4-6 parts of xylene. The anti-freezing external wall coating material of the present invention can resist the low temperature, and can keep good adhesion and good toughness at a low temperature so as to well improve the service life.

Description

technical field [0001] The invention relates to an antifreeze exterior wall coating, which belongs to the field of coatings. Background technique [0002] ​Exterior wall paint is used to paint the exterior walls of buildings. Exterior wall paint, because the coating is exposed to the atmosphere, has to withstand the effects of wind, sun, salt spray corrosion, rain, cold and heat changes, etc. Under the long-term repeated effects of these external natural environments, the coating is prone to cracking, Powdering, peeling, discoloration and other phenomena will make the coating lose its original decorative protection function. Especially in the northern part of our country, the weather is cold in winter, which puts forward higher requirements for the cold resistance of exterior wall coatings. If the cold resistance is insufficient, the coating will become stiff and easy to fall off, resulting in a reduction in service life and increased use costs. . Contents of the inventi...

Problems solved by technology

Especially in the northern part of our country, the weather is cold in winter, which puts forward higher requirements for the cold resistance of exterior wall coatings. If the cold resistance is insufficient, the coating will become stiff and easy to fall off, resulting in a reduction in service life and increased use costs.
