Novel water-based flame-retardant paint

Abstract

The invention discloses novel water-based flame-retardant paint. The novel water-based flame-retardant paint is prepared from, by weight, 100-150 parts of water-based polyurethane emulsion, 40-60 parts of epoxy resin, 15-20 parts of hydroxyethyl cellulose, 32-45 parts of aluminum triphosphate, 20-40 parts of mixed solvent of absolute ethyl alcohol and N,N-dimethylformamide by the volume ratio of 1:20-1:2, 14-28 parts of a nitrogen-phosphorous compound flame retardant, 6.5-7.3 parts of methyl dimethyl phosphate, 3.8-4.5 parts of an isocyanate compound and 1.4-2.8 parts of a defoaming agent. The paint is high in flame-retardant property and paint adhesion, has an anti-rust effect and high water resistance on a smearing face, reduces environmental pollution, is small in damage to the human body and reaches the environmental protection standard of paint.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a novel flame-retardant water-based coating. Background technique [0002] The problem of metal corrosion pervades all aspects of the national economy, especially the performance and commercial value of metal products will be greatly damaged, and even cause major failures to make equipment scrapped. Therefore, the problem of metal rust prevention has attracted more and more people's attention. Pay attention, especially when applying anti-corrosion coatings has become the most economical and effective anti-corrosion method. Most of the coatings now use solvent-based coatings. Solvent-based coatings can not only seriously endanger the health of users, but also pollute the atmosphere and destroy the ecology. Environment. At present, many anti-corrosion coatings contain sodium nitrite composite corrosion inhibitors, which have a bad impact on the environment. Although metal is also...

[0002] The problem of metal corrosion pervades all aspects of the national economy, especially the performance and commercial value of metal products will be greatly damaged, and even cause major failures to make equipment scrapped. Therefore, the problem of metal rust prevention has attracted more and more people's attention. Pay attention, especially when applying anti-corrosion coatings has become the most economical and effective anti-corrosion method. Most of the coatings now use solvent-based coatings. Solvent-based coatings can not only seriously endanger the health of users, but also pollute the atmosphere and destroy the ecology. environment, currently many anti-corrosion coatings contain sodium nitrite composite corrosion inhibitors, which have a bad impact on the environment

Although metal is also a material that is not easy to burn, although the temperature changes, its thermal stability will decrease, reducing its flame retardant effect, and prolonging its service life has become the focus of people's attention.
