Polystyrene plastics flame retardant
2017-12-4 11:15:55
Polystyrene plastics flame retardant are widely used in electronics, instrumentation and automotive industry. The flame retardants of polystyrene plastic flame retardants are used in components with high flame retardancy requirements.
Polystyrene plastics flame retardants are as follows:
(1) addition of brominated flame retardant
There are commonly used, deca brominated polystyrene (BPS), brominated epoxy resin (BER), double (three - methoxy) ethane. For example: brominated flame retardant additive 10%-15%, three oxidation of 3%-5% two antimony containing 30% glass fiber PBT can reach UL94 V-0 level, the oxygen index reached 27%-29%. The use of additive flame retardants must be paid attention to the dispersity, exudability, and the effect on the gloss and mechanical strength of PBT and PET.
(2) adding brominated phosphate
The three (dibromo phenyl) phosphate (TDBPPE) is commonly used because of the Br and P elements in the same molecule, so it has a synergistic effect of halogenated phosphorus. The flame retardant efficiency is very high in PBT and PET. What we should pay attention to here is to add frequently in the flame retardant treatment. Three oxidation and two antimony will synergy. If we do the oxygen index test, the limit oxygen index will increase, but in the oxygen enriched test environment, Sb and P will have a mutual antagonistic effect. Therefore, it is the most suitable to use the UL94 vertical combustion method to evaluate the combustion performance of the system.
(3) flame retardant PET is used as flame retardant fiber and fabric. There are usually two methods: one is to use six Bromination and twelve alkane to treat PET fabric as flame retardant. This fabric can be used for curtains, curtain, wall and other indoor decorative cloth bag. Because of the treatment of post finishing, the flame retardant is easy to exudate, the fabric feel and the flame retardant durability will be less. The other is the modification by copolymerization and flame retardancy. These reactive flame retardant monomers are mainly brominated aromatic compounds, aryl containing phosphine oxide compounds, brominated aromatic phosphine oxide compounds, etc. Because flame retardants become part of the molecular center of oligomers, it has many advantages, such as long flame retardant, good handle and light resistance. It is the main flame retardant method of PET flame retardant fiber and fabric in China.
The research and development of the flame retardancy mechanism of boron - silicon flame retardant are in the bud. Some people think that the boron - silicon flame retardant in the combustion of boron to carbon catalytic form, and increase the stability of silicon formed by carbon layer; two layered silicon oxide siloxane formation prevents oxidative degradation of carbon layer, improve the stability of carbon layer, so as to achieve the effect of flame retardant.
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP)
CAS No.:13674-87-8
HS: 29199000
Tax Rate (%): 9%
Tris (1,3-Dichloro-2-Propyl) Phosphate (TDCPP) Raw Materials: Phosphorus Oxychloride, Epichlorohydrin
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP) Use:
The Product Has A High Efficiency Flame Retardant, Low Volatility, High Thermal Stability, Water Resistance, Alkali Stable And Soluble In Most Organic Substances, Processing Performance, With Plastic, Moisture, Anti-Static, Anti-Pull, Anti-Compression Performance. Widely Used In Unsaturated Polyester, Polyurethane Foam, Epoxy Resin, Phenolic Resin, Rubber, Soft Polyvinyl Chloride, Synthetic Fibers And Other Plastics And Coatings At High Temperature Pyrolysis, Can Be Used As Emulsifier And Explosion-Proof Agent.
Organic silicon flame retardant materials with high efficiency, non-toxic, low smoke, no pollution, no droplet characteristics in non halogen flame retardant is free in many real, favored, but there are more expensive problems. The introduction of two elements of silicon and boron to the same molecular structure can reduce the price and improve the hydrolysis stability of the boron retardant. The structure composed of boron oxygen chain and silicon oxygen chain, as flame retardant and flame retardant resin polymer mixed with PC, PET, PBT and ABS resin, has good flame retardance effect and is very valuable for resin industry. However, if it is used alone on cotton fabric, the effect of flame retardancy is not good enough.
The researchers will have three phenyl chlorosilane and boric acid reaction, get a molecule containing oligomer ring structure of silicon and boron as a flame retardant, used for cotton fabric, has good flame resistance, and can improve the stability to hydrolysis resistance of boric acid ester.
In recent years, due to some erroneous understanding of brominated flame retardants and pressure from some environmental organizations, some downstream users of flame retardants, especially the producers of electronic devices, have to use halogen free flame retardants instead of brominated flame retardants.
In 2010, Panasonic has to meet the requirements in the refrigerator and halogen free product of the use of red phosphorus flame retardant instead of brominated flame retardants, resulting in a fire hazard, then had to recall 360 thousand refrigerators, and replacement parts to use brominated flame retardants.
A kind of diatomite flame retardant and its production method belong to the processing technology of inorganic materials in chemical field.
Using diatomite as raw material, through crushing, drying, sorting and adding masking agents and impurities in high temperature roasting, the organic matter in diatomite complete oxidation combustion, decomposition of carbonate mineral impurities in digestion, transformation of iron compounds into white, improve product whiteness and chemical stability. The processing technology of diatomite finished products has three stage crushing, four grading and one-time separation and recycling process, and the third stage comminution has adopted supersonic airflow crushing. The products are non-toxic and non corrosive, and can be applied to plastics, rubber, plastic, paint and coatings as additive flame retardant, and can also be used as filler for paper making.
Most of the plastic products have flammability, which has brought many hidden dangers to the safety of its products. Precisely, flame retardants are more appropriate as combustible agents, because "flammability" contains two layers of flame retardancy and smoke suppression, which are more widely used than flame retardants. However, for a long time, people have been accustomed to using the concept of flame retardants, so the flame retardants mentioned in the literature are actually the general name of flame retardants and smoke suppressants.
