Red phosphorus flame retardant
Since the 1960s, red phosphorus flame retardant has been applied to synthetic resin. It is mainly used as flame retardant with polyurethane and oxygen resin, and has achieved good flame retardant effect. In 1974, the technology of adding red phosphorus flame retardants to glass fiber reinforced nylon was introduced.
In early 70 s, the red phosphorus are directly added to the polymer, because of the red phosphorus combustible dust, big risk, when using, as an inorganic red phosphorus and the compatibility of resin is poorer, eventually will influence the mechanical properties of the products. During the 70 s began to stabilization of red phosphorus microcapsules, first successfully developed in 1984 for thermoplastic phenolic resin coated red phosphorus, and used in nylon 66 glass fiber enhancement, greatly improving the impact strength of the product. Added to enhance, fill in thermoplastic plastic wrap red phosphorus, obtained good result. By the end of the 1980s, the technology of red phosphorus capsules was becoming more and more mature.
The research and production of red phosphorus flame retardant in our country started late, but it developed very quickly. In the late 1990s, we began to study and develop the production of red phosphorus. With the continuous development of China plastics industry and the improvement of products, especially after China's accession to the WTO, industry standards and regulations gradually and the world, increasingly strict with plastic fire and flame retardant.
Fire modification of plastics, the world's widespread use is containing halogen flame retardants (ten pbdes), because of the high containing halogen flame retardant efficiency, less to measure, small influence on material properties, and the price is moderate. However, the halogen flame retardant can produce a lot of smoke and toxic gases during the process of processing and pyrolysis. It has a strong corrosive effect on the equipment, which seriously affects the health of the operators.
In recent years, some European Union countries have thought that the flame retardants of bromine will produce high carcinogenic polybromophenol (PBDD) and polybrominated diphenyfuran (PBDF). In February 2003, the European parliament and the council launched two ban, ROHS and WEEE regulations since July 2006, shall be prohibited in the eu market sales with phosphorus-containing flame retardants (ten pbdes) electronic plastic products, electrical appliances. China has also announced the cessation of the use of halogenated flame retardants for six toxic components, including lead, cadmium, mercury and polybrominated biphenyls, since March 2007.
Triisobutyl Phosphate (TIBP)
Cas No:126-71-6
HS Code HS: 29199000
The most important indicator of product: colorless transparent liquid Content ≥ 99%, moisture ≤ 0.2, Acid value ≤ 0.1, Chroma ≤ 20
Raw materials:phosphorus oxychloride and isobutanol as the main raw material.
Belong to several categories of dangerous goods:
Currently Triisobutyl Phosphate(TIBP) general cargo exports are not dangerous.
Packing: NW 200KG / galvanized iron (a small cabinet loaded 16 tons a child care), 1000KG/IB barrels (a small cabinet loaded 18 tons), or 23 tons ISOTANK.
Triisobutyl Phosphate(TIBP) is mainly used for antifoamer and penetrant. It is also be widely used in printing and dying, ink, construction, and oil field additives, etc. Another chemical name of Triisobutyl Phosphate (TIBP) is tri -butyl phosphate.
After a long time and the use of the test show that red phosphorus flame retardant is a kind of high performance, low dosage can reach excellent flame retardant effect, due to the add quantity is little, the mechanical properties of materials, especially the electric performance is affected. For example, in nylon materials, halogenated flame retardants are processed at the processing temperature, and the reaction of hydrogen halide with nylon on the amide base is easy, so that the extrusion products are foamed. Additionally, phosphor flame retardant can greatly improve the trace index of nylon material.
Red phosphorus is the only element that can be used in flame retardants. Its flame retardant mechanism is different from halogen flame retardant, the former is solid phase inhibitory type, the latter is gas phase inhibitory type. Red phosphor is used to produce polyphosphoric acid in the heat and oxygen in the air. Polymetaphosphoric acid is a stable compound which is not volatile and forms an isolation layer on the surface of the burner. In addition, due to the dehydrating effect of polymetaphosphate, the formation of carbonized layer on the surface is formed, the oxygen is cut off, and stable at quite high temperature. Red phosphorus is especially effective for oxygen-containing polymers!
According to the needs of the market, the plastics manufacturers in east China and south China are already choosing and adopting low - toxic environmental flame retardants that meet the international requirements.
In recent years, the research and production of low smoke, low toxicity, and non-halogenated high efficiency red phosphorus flame retardant mother granule products in China. It has good process performance and safety relative to red phosphorus powder. It can be flame retarded by the following polymers.
1. Engineering plastics (PA6, PA66, PBT, PC, MC nylon)
2. General plastic (PE, PP, EVA, EAA, EPR)
3. Thermosetting resin (polyurethane, epoxy resin, unsaturated polyester)
