In order to increase the flame resistance of polymer materials, it is mainly used for polymer materials such as plastics, rubber, fibers, etc., and most of these materials can be burned. In particular, plastics, to be used in transportation, construction, electrical equipment, aviation, space flight and other aspects, it is urgent to solve the problem of its combustion resistance.

TCEP flame retardants are mainly organic and inorganic compounds containing phosphorus, halogen, boron, antimony and other elements. Usually according to the method of use, the TCEP flame retardant is divided into reactive and additive two categories: reactive flame retardant in the polymer synthesis as a component to participate in the reaction, mainly used in thermosetting plastics; TCEP flame retardant is added in plastic processing, generally used in thermoplastics.

TCEP flame retardant is an important development direction of halogen-free flame retardants. At present, Al(OH)3 and Mg(OH)2 flame retardants are more mature and have a certain market share. The flame retardant mechanism is mainly by reaching the thermal decomposition temperature of rapid decomposition, endothermic cooling, the release of water vapor to reduce the temperature of the system, while water vapor and diluted the flammable gas to achieve flame retardant effect.

The amount of TCEP flame retardant is very large, which may lead to changes in the physical and mechanical properties of polymers. In order to improve these defects, inorganic flame retardants are treated by microparticle and surface activation. The former allows it to be dispersed evenly in the polymer, the flame retardant effect is homogenized in the bulk phase, and the amount of flame retardant is reduced. The latter improves the adhesion and interfacial affinity between inorganic flame retardants and polymers by surface modifiers (sodium stearate or sodium oleate), which not only improves compatibility, but also reduces the amount of flame retardant materials while maintaining mechanical strength.

Antimony trioxide (also referred to as antimony oxide, commonly known as antimony white) molecular formula: Sb2O3 molecular weight: 291.5 Antimony trioxide is one of the inorganic flame retardants that have been used for a long time. It is mainly used as a flame retardant synergist to cooperate with halogen-containing compounds. It plays a flame retardant role in their thermal decomposition process and can replace some halogen compounds. It can be applied to plastics, rubber, chemical fiber, enamel, pigment, paint, glass, glass, electronics and other industries.

3.5 zinc borate water molecular formula: 2ZnO • 3B2O3 • 3.5H2O molecular weight: 434.51. Zinc borate is an inorganic additive flame retardant, which is characterized by good thermal stability, I .e. flame retardant and smoke elimination. It can replace antimony trioxide in some products and can also be used in conjunction with other inorganic flame retardants with better effect. Anhydrous zinc borate molecular structure formula is 2ZnO · 3B2O3, white powder, excellent fluidity, temperature resistance to 600 ℃, low heat release rate. Very low water solubility, no migration, and excellent charring performance, can be compounded with other additives into halogen-free expansion flame retardant, can be used as a high processing temperature polymer (polyether ketone, polyalum, polyester, nylon, fluorine-containing polymer, etc.) excellent flame retardant and smoke suppression agent.
