Polyolefin plastic brominated flame retardants
At present, the development of domestic environment-friendly plastics flame retardants has attracted the attention of all sides. At the same time, people's requirements for fire safety and plastic flame retardants products have also improved one level. Halogen free, low smoke and low toxic environment-friendly plastics flame retardants have been the new goals pursued by people.
It is known that 80% of the modified plastics in China are halogen - containing flame retardants, which are also represented by polybrominated two benzyl ether and polybrominated biphenyl. Polyolefin plastics, brominated flame retardants, have high efficiency and less consumption. These plastics flame retardants have relatively little influence on the properties of materials, and the price of polyolefin plastics brominated flame retardants is moderate.
Compared with other types of plastic flame retardants, the price ratio of polyolefin plastics brominated flame retardants is more superior. In China, 70% to 80% of all electronic and electrical products for export are all polyolefin plastics brominated flame retardants. However, in recent years, some European Union countries have thought that polyolefin plastics brominated flame retardant can produce toxic carcinogens when they burn. As a result, the EU has banned the sale of products containing polybrominated biphenyl and polybrominated two benzyl ether.
The state of Illinois has proposed a bill to ban penta, octa, and DECA, HB2572. The revised bill has removed the restrictions on DECA products and requires more research on DECA.
Maine banned the use of penta and octa, the evaluation of alternatives is underway.
In 2004, Maryland proposed a bill HB83 for the use of brominated flame retardants. The amendment provides for the prohibition of the use of penta and octa, and DECA is to be further studied, which has been approved by the governor.
SB 553 / HB 1286 "Massachusetts health action: a safe substitute for toxic chemicals" is waiting for a vote on the environment and natural resources Federation. In a resolution on funding for research projects on the TURI, PBDEs is not the list of chemicals that will be banned.
Minnesota's motion for disabling penta, octa and DECA's bills or electronic and electronic wastes has not changed.
The state of Montana failed to pass the bill for the elimination of PBDEs and the use of alternatives.
Penta and octa in New York have been banned, and a DECA advisory board is now being set up as the representative of the evolutionary physical sciences and Environment Forum (BSEF).
In Oregon, a bill (SB962) has been banned for bromination of flame retardants. The amendment proposes a ban on the use of penta and octa and checks DECA every other year. The bill has been passed and the governor has approved it.
Triphenyl Phosphate (TPP)
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.
There is a proposal of electronic and electrical waste which lists bromine flame retardants as harmful substances in Lanzhou, but it will be modified to remove bromine flame retardants.
Washington, January 2004. In response to the governor's request. The ecological Department works with the health and health department to study how to reduce the harm of PBDEs to the environment. In addition, there have been proposals for the prohibition of the use of PBDEs products, but they have not been adopted. The chemical guidelines for the state pointed out that the harmfulness of DECA is not clear at present. It is recommended that a ban be issued after finding suitable substitutes or confirming the harm of DECA.
Canada's brominated flame-retardant related proposals were introduced from the time of the founding of the new parliament, but the Canadian health department's environmental protection agency has not issued a notice of prohibition so far.
The Chinese mainland and Taiwan will follow the requirements of the RoHS ban. In addition, DECA also attracted some attention of independent institutions, they are applied to the safety of consumer goods DECA, mainly includes the following aspects: children of chemicals (VCCEP); voluntary assessment program of the National Science Research Institute; the U.S. Consumer Product Safety Commission (CPSC); the British Ministry of trade and Industry: the advantages and disadvantages of the application of flame retardants.
Like DECA, the alternatives of flame retardants have not been thoroughly measured and characterized. Because of the unknown factors such as human health and environment, the use of DECA substitutes will probably not get the desired results.
However, the market for flame retardants is gradually globalized, and the changes in a country or region will have an impact on the world. Therefore, the conclusion that "all bromine flame retardants are not good" only by feeling is that it is costly and unfounded.
Solid state flame retardants increase the viscosity of materials, while liquid flame retardants reduce the viscosity of liquid. They can be used together, not only having synergistic effect, but also adjusting the viscosity of reactive materials, and obtaining high flame retardant products.
