Fire retardant is also called fire retardant and Shanghai flame retardant. Can maintain plastic products, textiles, wood and other agents that do not catch fire or make the flame slowly spread. Mainly because the medicine can generate a large amount of non-combustible gas or the medicine film cannot be burned, the purpose of fire prevention is achieved.

A carbonaceous layer with a porous structure is formed under the action of a dehydration carbon-forming catalyst. The fire-proofing aid in the intumescent fireproof coating is mainly composed of a carbonizing agent, a dehydrating carbon-forming catalyst, and a blowing agent. High-carbon polyhydroxy organic compounds. The material basis of the foamed carbonized layer that forms a three-dimensional spatial structure and is not easy to burn, plays a skeleton role in the foamed layer. The main role of the dehydration to carbon catalyst is to promote the dehydration of the carbonizing agent and the coating , Carbonization and thermal decomposition process, dehydrating the polyhydroxy compounds to form a non-combustible carbonaceous layer, reducing the amount of flammable tar, aldehydes, ketones, etc. generated by organic matter due to thermal decomposition, and effectively preventing the occurrence of large-calorie oxidation reactions Foaming agent is an important additive that affects the fire resistance of coatings, which causes the coating to decompose non-combustible gases during heating, which isolates the contact between the substrate and the air, and expands the coating on the other hand. Forms a loose and porous foam layer, which suppresses the progress of combustion.
