High-flame-retardation fireproof exterior wall coating for buildings

Abstract

A provided high-flame-retardation fireproof exterior wall coating for buildings comprises the following components in parts by weight: 10-20 parts of calcium chloride powder, 10-20 parts of titanium dioxide, 20-30 parts of talcum powder, 30-50 parts of organic soil, 20-30 parts of heavy calcium carbonate, 5-10 parts of a dispersant, 10-20 parts of styrene, 20-30 parts of 2-ethylhexyl acrylate, 40-80 parts of water, 8-20 parts of glycol, 1-3 parts of an antifoaming agent, 0.1-0.8 part of a mildew inhibitor, 33-45 parts of fluorocarbon resin, 10-18 parts of a fire retardant, and 0.1-0.9 part of a levelling agent. The high-flame-retardation fireproof exterior wall coating for buildings employs a unique coating formula, is simple in preparation process, strong in adhesion force and uneasy to shed, possesses relatively good fireproof mildew-preventing efficacies, is convenient to construct, and is especially applicable to exterior wall coating of buildings at areas with relatively high air humidify.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a high flame-retardant and fire-resistant building exterior wall paint. Background technique [0002] Coating is a kind of material, which belongs to fine chemical products. The service life of the paint depends on different products, and the service life of the exterior wall paint is about 15 years. Modern coatings are gradually becoming a class of multifunctional engineering materials and an important industry in the chemical industry. At present, the coatings on the market have a single function and cannot meet people's needs. And fireproof coatings in the prior art often only pay attention to indicators such as fireproof performance and bonding performance, and often ignore indicators such as coating environmental protection performance, impact resistance, impermeability and waterproof performance, and mildew resistance. Contents of the invention [0003] In view of this...

Problems solved by technology

At present, the functions of coatings on the market are relatively single, which cannot meet people's needs.

Moreover, fireproof coatings in the prior art often only pay attention to indicators such as fireproof performance and bonding performance, and often ignore the indicators such as environmental protection performance, impact resistance, impermeability and waterproof performance, and mildew resistance of the coating.
