What is flame retardant resin? What are the applications of flame retardant resin? Is there any expert who can help me?

The important role of flame retardant resin in social development. Due to the use of flame retardants in Europe in recent ten years, the number of fire deaths has dropped by about 20%. The safety of flame retardant materials is also very important. It is a slow and difficult process to standardize the use of materials in industry. At present, many halogen-based and phosphorus-based flame retardants have been and are being evaluated by the European Union, and many of them will be completed in 2004 -2006. At present, in China, reactive flame-retardant resins are generally prepared from halogen compounds of dihydric alcohols or dibasic acids containing chlorine or bromine. Halogen flame retardant will produce a lot of smoke when burning, accompanied by the generation of highly irritating hydrogen halide. This kind of thick smoke and poisonous fog produced in the combustion process has caused great harm to people.

According to statistics, more than 80% of deaths in fire accidents are caused by this. Another disadvantage of using bromine or chlorine as flame retardant is that corrosive and polluting gases will be produced when burning, which will cause damage to the original electrical appliances. Inorganic flame retardants, such as hydrated alumina, magnesium, boron, molybdenum compounds and other flame retardant additives, have obvious smoke suppression effect and can produce flame retardant resins with low smoke and low toxicity. However, if the amount of inorganic flame retardant filler is too large, not only the viscosity of the resin will increase, but also the mechanical strength and electrical properties of the resin after curing and molding will be affected. At present, many foreign patents report the technology of producing low toxicity and low smoke flame retardant resin with phosphorus flame retardant. Phosphorus flame retardant has obvious flame retardant effect. Metaphosphoric acid produced during combustion can be polymerized into a stable poly-state, forming a protective layer, covering the surface of the combustion object, isolating oxygen, promoting dehydration and carbonization of the resin surface, forming a carbonized protective film, and preventing combustion. At the same time, phosphorus flame retardants can also be used in combination with halogen flame retardants, which has a very obvious synergistic effect. Of course, the future research direction of flame retardant resin is low smoke, low toxicity and low cost. The ideal resin is smokeless, low-toxic, low-cost, does not affect the inherent physical properties of the resin, and can be directly produced in the resin factory without adding additional materials.

The above data fully shows that flame retardant materials are as important as drug rescue, and flame retardant materials can avoid or reduce disasters.
