Problems solved by technology

The main additions in the patent are additive flame retardants. Although they can play a flame retardant effect, such flame retardants have poor flame retardant effects, large dosage, poor compatibility with organic components, and need to add a variety of chemical Additives improve the performance of coatings, which greatly reduces the environmental protection of water-based coatings
Simultaneously, as a water-based coating, the rapid curing performance of the flame retardant coating composition is not ideal

Abstract

The invention provides a water-based flame-retardant paint and a preparation method and application thereof. The water-based flame-retardant paint is prepared from the following components in parts by weight: 10 to 15 parts of acrylate, 3 to 5 parts of sulfate, 10 to 15 parts of polyvinyl alcohol, 5 to 10 parts of iso-octyl acrylate, 3 to 5 parts of triallylamine, 3 to 5 parts of fatty alcohol-polyoxyethylene ether with a molecular weight of 400 to 1200, 3 to 5 parts of curing agent, 10 to 15 parts of fillers, 12 to 20 parts of dispersing agent and 30 to 45 parts of water. By adding the iso-octyl acrylate, the triallylamine and the fatty alcohol-polyoxyethylene ether with the molecular weight of 400 to 1200 into the raw materials, by virtue of the synergistic effect, the water-based flame-retardant paint is obtained by virtue of modification, so that the paint has good compatibility and flame retardant property.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a water-based flame-retardant coating and a preparation method and application thereof. Background technique [0002] Flame-retardant coatings are the most widely used, most adaptable, and most convenient construction materials in modern engineering, and they have played a huge role in ensuring the safety of buildings. With the improvement of people's living taste, people are more fond of building materials such as wooden structures and steel structures. On the one hand, the flame-retardant coating has a beautiful effect on the above materials, on the other hand, when a fire occurs or is subjected to high temperature, the flame-retardant coating has a good protective effect on wood and steel structures, and is a good flame-retardant and heat-insulating building material. [0003] Water-based polyurethane coating is a kind of coating based on water-based polyurethane resin and dis...
