(1) carbon technology

Burning polymer, in condensed phase sintered carbon can achieve the purpose of flame retardant. In the material surface carbon deposition thickness of 1 mm, can bearhigh temperature of 743 DEG C without fire. In the paint, pentaerythritol, melaminepolyphosphate press and pop amines can be used as a good catalyst, carbonizationcarbonization agent and foaming agent. As the three according to a certain proportionis added into the coating, can be made of fire retardant coating with excellent properties.

Three kinds of flame retardant agent with prospects of new technology

In addition, polymer blend carbonization with polymers and cannot easily carbonized,has good flame retardant effect, such as the easy carbon deposition of polyphenylene ether and high impact polystyrene blends, because the CAN node carbon and greatly improve the flame retardancy; halogenated flame retardants such as adding a small amount of gas fire extinguishing with flame retardant. High performance carbon. Thistechnology will be widely used.

(2) the elimination smoke technology

Due to the addition of flame retardants in polymers, can make the amount of smoke is increased, so the smoke and become an important research topic. The smoke eliminating agent is able to reduce the additive amount of smoke and smoke densityeffectively, with focus on the application of the smoke eliminating agent is PVC, smoke and resistance to your agent containing key compound is the most effective agent foreliminating smoke. In addition to the three key and eight aluminum acid by oxidation,smoke eliminating agent key acid zinc developed abroad is poisoning rate is low andexcellent flame retardance smoke eliminating agent. Because the aluminum priceexpensive, so we often use boric acid zinc, aluminum hydroxide, zinc, silicon and phosphorus compounds and a small amount of aluminide compound added after, this is a realistic approach to solve the problem of smoke.

(3) microencapsulation technology:

Migration of microencapsulation can prevent flame retardant, improve the flame retardant effect, improve the stability and the change of dosage form.

Study on microencapsulation technology has become the frontier research of flame retardant technology. In recent years, the existing foreign microcapsule products,such as the Freon fluorocarbon DuPont Co with polymer to make itsmicroencapsulation, and used PVC, PP, and PVR (polyurethane), the effect is very good.

(4) the particle:

Aluminum hydroxide, magnesium hydroxide, antimony oxide flame retardant, require the use of new technology, the new device makes the particles, to improve their mobility, processing, improve the flame retardant effect. The average particle size ofaluminium hydroxide and meets the requirements of 15m, the finer granularity is required for antimony oxide. As the flame retardant fiber treated with particle size of 0015^'0. 025m Sb2O3 colloid, resistance emblem effect is improved by 8 times, the other properties are improved.
