Bromine antimony grade flame retardant
With halogen flame retardant refers to contain halogen polymers or combination containing halogen flame retardant flame retardant compounds, are mainly antimony trioxide and ten pbdes, is often said that the antimony bromide flame retardants, bromine and antimony flame retardant with excellent flame retardant properties, have been widely used as resistance material material.
However, when a fire occurs, the heat produced by such use of a brominated antimony flame retardant produces a large amount of smoke and toxic and corrosive hydrogen halide gas, resulting in a secondary hazard.
In February 2003, the European Union has issued two WEEE and RoHs instruction, WEEE is about the recycling of waste electrical and electronic equipment directive, RoHs is about restrictions in electronic electrical equipment and ban the use of some poisonous and harmful substances and elements of the instructions. In August 2004, the two orders were converted into laws (regulations) in the 15 member states of the European Union.
Western Europe began to implement new flame retardant classification methods and test standards in line cables, building materials, coatings and other industries. China has also begun to register national standards for building materials and grades of combustion performance.
China flame retardant performance level and the national institute of standards and new standards of Western Europe has many same characteristics, that is: to emphasize the development rate of fire, heat release rate, smoke and corrosive products of combustion and toxicity to the standard of judging flame retardant performance. In order to pass such new standards, the traditional halogenated antimony and halogen flame retardant materials will appear powerless.

Tert Benzyl diphenyl phosphate (BPDP-71B) use
Tert-butyl phosphate diphenyl phosphate, tert-butylated triphenyl phosphate is halogen-free organophosphorus flame retardant, using a new, excellent performance of phosphorus flame retardant, with excellent thermal stability and hydrolysis Sex. Its high thermal stability makes it as an engineering plastic flame retardant at the same time, can improve the plastic melting performance. Tert-butylated triphenyl phosphate for the liquid, in the resin can make its durability and hydrolysis stability is better, and easy to produce the table and stress cracking. It is widely used in flame retardant PV (, cellulose resin, into the rubber, phenolic resin, epoxy resin, polyene unit fiber.
New flame retardant system, the smoke quantity is small when combustion, do not produce corrosive, poisonous gas. Halogen - free flame retardant mainly based on phosphorus and metal hydroxide.
The traditional flame retardant materials are widely used in combination with halogen polymer or halogen flame retardants. The advantages of halogen flame retardants are low dosage, high flame retardant efficiency and wide adaptability, but its serious disadvantage is that it produces a large amount of smoke and toxic and corrosive gas during combustion, which is very harmful. In the event of a fire, due to thermal decomposition and combustion, a large amount of smoke and toxic corrosive gases are produced, thereby preventing fire and personnel evacuation, corrosion equipment and equipment. In particular, more than 80 percent of the deaths from fires are found to be caused by smoke and toxic gases from the material. Therefore, the research and development of halogen-free flame retardants should be taken seriously.
The development of bromine series flame retardant bromide flame retardants in spite of large amount of smoke, but as a result of good flame retardant performance, less dosage, small impact on product performance, so in a reasonable period of time in the future is still the main flame retardants. With the development of technology, the new development of the international bromine flame retardant is to continue to increase the bromine content and increase the molecular weight.
The main components of pb-68 are brominated polystyrene, with a molecular weight of 15,000 and bromine by 68%. Polypentabromophenol acrylate, which has a bromine amount of 70.5%, has a molecular weight of 30,000 ~ 80,000. These flame retardants suitable for all kinds of special engineering plastics, the migration, compatibility, thermal stability, flame retardancy, etc are much better than many small molecules flame retardant, has the potential to be the updated products in the future.
Halogen-free flame retardants have - W666 is a high-performance phosphorus and nitrogen organic fire retardant agent, is a kind of triazine three ketones compounds and triazine amine compounds, through a special surface treatment, so easy to disperse in the plastic material, not precipitation, has excellent flame retardant effect. W666 decomposition temperature about 450 ℃, the maximum particle size distribution (D50 %) of 20 / um, appearance is white powder, is a kind of color does not affect the product's resistance to high temperature of high-performance halogen-free flame retardants recommended for polyamide (nylon) are widely used in epoxy resin, polyurethane, polystyrene, polyester (PET, PBT), polyolefin and halogen-free, wire and cable suggested adding 15% 15% of halogen free flame retardant W666, would be able to reach the where V0-94 ul standard of V2.
