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

Embodiment 1

[0048] Embodiment 1: the preparation of epoxy modified alcohol ester

[0049] The ratio of raw materials used is as follows:

[0050] 0.7 parts of bisphenol A epoxy resin

[0051] 1.2 parts of maleic anhydride

[0052] 13 parts of ethylene glycol

[0053] In a nitrogen atmosphere, weigh the raw materials according to the above ratio and add them to the reactor, react at 110°C for 55 minutes, then add 8 drops of hydrochloric acid dropwise, and continue the reaction for 12 minutes to obtain epoxy-modified alcohol ester.

Embodiment 2

[0054] Embodiment 2: the preparation of epoxy modified alcohol ester

[0055] The ratio of raw materials used is as follows:

[0056] Bisphenol A epoxy resin 0.5 parts

[0057] 1 part maleic anhydride

[0058] 10 parts of ethylene glycol

[0059] In an argon atmosphere, weigh the raw materials according to the above ratio and add them to the reactor, react at 100°C for 50 minutes, then add 5 drops of hydrochloric acid dropwise, and continue the reaction for 10 minutes to obtain epoxy-modified alcohol ester.

Embodiment 3

[0061] Preparation of Epoxy Modified Alcohol Esters

[0062] The ratio of raw materials used is as follows:

[0063] 0.8 parts of bisphenol A epoxy resin

[0064] Maleic anhydride 1.5 parts

[0065] 15 parts of ethylene glycol

[0066] In an argon atmosphere, weigh the raw materials according to the above ratio and add them to the reactor, react at 120°C for 60 minutes, then add 10 drops of hydrochloric acid dropwise, and continue the reaction for 15 minutes to obtain epoxy-modified alcohol ester.

Abstract

The invention provides a water-based flame retardant coating. The water-based flame retardant coating comprises the following components in parts by weight: 20-30 parts of acrylate, 5-10 parts of sulfate, 0.2-0.4 part of potassium sulfate, 1-2 parts of nonylphenol polyoxyethylene ether, 8-12 parts of epoxy modified alcohol ester, 5-6 parts of tetraethoxysilane, 3-5 parts of a curing agent, 10-15 parts of filler, 12-20 parts of a dispersing agent and 30-45 parts of water. The water-based flame retardant coating has the beneficial effects that by applying an organophosphorus ester compound to the coating to form a synergistic flame retardant system with silicon, the coating has good compatibility and flame retardance; meanwhile, the coating has excellent adhesive property, is low in cost, has good component compatibility, is environmentally friendly and flame-retardant and has excellent application value.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a flame-retardant coating composition. 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 dispersed in water level. It has good storage stab...
