Environmental protection type bromine flame retardant

Environmental protection type bromine flame retardant decoct-diphenyl ethane. 8010 does not belong to polybrominated diphenyl ether, it is absolutely impossible to produce PBDD or PBDF in combustion. The relative molecular weight of 8010 is 971; The bromine content is 82%, and DBDPO has a bromine amount (83%), so the flame retardant performance is basically the same.

Stability were DBDPO melting point 345 ℃, at the beginning of the high (305 ℃); It is superior to DBDPO for its light resistance and non-permeable analysis. The most valuable thing is that its flame retardant plastic can be recycled, which is a characteristic that many bromine flame retardants do not possess. 8010 industrial products are the average particle size of 3 mu m, free flow and microgranulation of white crystalline powder, which is easy to disperse in plastic modification, and the color of plastic products is free. And the industrial cost is the same as DBDPO, which is the ideal substitute for DBDPO.

As the added bromine flame retardant, 8010 is used in conjunction with antimonide, with the same proportion as DBDPO/antimony ratio. Compared with DBDPO, 8010 is more suitable for high temperature and high viscosity engineering plastics.

The flame retardant is also called tetrabromobisphenol A epoxy resin with brominated epoxy resin. The bromine content can reach 50%, and the molecular weight is between 1000 and 45,000, which is divided into EP type and EC type. Compared with the EC type, the former has better light resistance and lower bromine content, while the latter has better anti-impact strength. Commercial brominated epoxy resin is a mixture of cream - yellow translucent wafers and white powder. Brominated epoxy resin has satisfying the melt flow rate and high flame retardant efficiency, excellent thermal stability and light stability, and can give good flame retardant base material mechanical properties, the product can't afford to cream.

Low phase molecular weight bromide epoxy resin is suitable for fire retardant ABS and HIPS, high phase molecular weight is suitable for fire retardant ABS/PC alloy and PC, PET, PBT and other engineering plastics. It is used in conjunction with antimonide in use.

The development of environment-friendly brominated flame retardant brominated polystyrene is similar to that of brominated epoxy resin, and is also a new type of flame retardant. Brominated polystyrene is white or light yellow powder or granule, bromine content is around 60%. Thermal decomposition temperature greater than 310 ℃, with large molecular weight, good thermal stability, good dispersion and mixing in the high polymer capacitive, easy processing, no cream, etc.

Flame retardant TPP has many advantages, such as excellent transparency, softness, bacterial resistance, and water proof, grease-proof, good electric insulation, as well as good compatibility. Flame retardant TPP is mainly used as the flame-retardant plasticizer for cellulose resin, vinyl resin, natural rubber and synthetic rubber. And it may also be used as the flame-retardant plasticizer for glyceryl triacetate thin ester and film, rigid polyurethane foam, phenolic aldehyde resin, and PPO, etc.

Flame retardant TPP is a kind of halogen-free environment-friendly flame retardant with phosphorus element. Most of the products in the market are self-colored flaky crystal, our product is self-colored crystalline powder, and is more soluble in organic solvents. TPP is not soluble in water, but soluble in benzene, chloroform, ether and acetone, and slightly soluble in Z alcohol. Flame retardant TPP is nonflammable with slight aromatic odor and slight deliquescence. The fusion point is about 50 ℃, and fast melts to hoop-shape when heated. The lubricate effect is excellent, and it is often used as the flame retardant plasticize lubricant. What is more, it is used as the flame retardant for many plastics and resins, such as phenolic aldehyde resin, epoxy resin and so on.


Environmental protection bromine flame retardants brominated polystyrene on the basis of the synthesis way named respectively brominated polystyrene and poly (styrene brominated, can be seen from the name on the brominated polystyrene is done through to brominated polystyrene; Polybrominated styrene is used to protect the styrene first, then bromide, then restore the keene bond, synthesize brominated styrene, and complete the polymerization again. Solvent and non-solvent methods can be divided into the use of solvents from the synthesis process. Solvent method is usually used to synthesize the solvent.

Brominated polystyrene is mainly used in thermoplastic resins such as PA, PBT and PET, which are used in conjunction with antimony compounds. When flame retardant polyester is added, the amount of addition is 13% (enhancement) ~ 17% (non-enhanced), which can be assigned to the material ul94v-o-class (0.8mm). When flame retardant polyamide is used, the amount of addition can be assigned to the material ul94v-o class (0.8mm).

Bromine flame retardant is easy to use and can be added directly in the post-processing of textiles (polyester, viscose, blended, cotton, pure polyester), finishing the whole process at normal temperature. Is pollution-free new fiber flame retardant, compared with the conventional product pbdes, the flame retardant join, when polymer cracking or burning, no poisonous diphenyl and two well alkanes and polybrominated diphenyl and furan produce.

The development of brominated polystyrene is similar to that of bromide epoxy resin, and is also a new type of flame retardant. Brominated polystyrene has a high molecular weight, good thermal stability, good dispersion and mixing capacity in high polymer, easy to process and no frost. It is mainly used in thermoplastic resin such as PA, PBT and PET.

Brominated polystyrene on the basis of the synthesis way named respectively brominated polystyrene and poly (styrene brominated, can be seen from the name on the brominated polystyrene is done through to brominated polystyrene; Polybrominated styrene is used to protect the styrene first, then bromide, then restore the keene bond, synthesize brominated styrene, and complete the polymerization again.
