Flame retardant for polyolefin materials
Reducing the flammability of polyolefin materials is the goal of materials research. Scientists have been studying the flame retardant of polyolefin materials.
Flame retardant polymer materials are mainly made of polymer matrix and flame retardant. By adding in the process of polymer materials in chemical reactive flame retardant or in polymer materials through reactive flame retardant has become a structural unit which gives flame retardant polymer materials.
In polyolefin flame retardant, the most commonly used method is to use filler type flame retardant. Compared with the structure flame retardant method, it has the characteristics of simple process, low cost, wide source of raw materials, easy operation and obvious flame retardant effect. Epoxy resin filler type flame retardant agent commonly used halide, phosphide, hydrated alumina, calcium aluminate and ammonium polyphosphate etc.. The flame retardant polyolefin materials when used alone can achieve good flame retardant effect, after pretreatment with other flame retardants with flame retardant is the use of a better effect.
Halogenated flame retardants, such as ten brominated diphenyl ethers, four bromo phthalic anhydride, two bromo red anhydride, and so on, are the first class of flame retardants. Halogenated flame retardants with high efficiency, low price, low added amount, good compatibility, flame retardant and good stability, can maintain the physicochemical properties of the original products, and the price, variety, wide use range.
At the same time, halogen flame retardant is also controversial because of a kind of flame retardant, halogen flame retardant, large amount of smoke, gas and hydrogen halide release has strong corrosive and toxic, hidden hazards two. Especially after the emergence of dioxin problem, the environmental safety problems caused by halogen containing flame retardants have attracted extensive attention. Due to the adverse effects of traditional halogenated flame retardants on environment and health,
The European Union has restricted the use of halogenated flame retardants since 2000. In 2003, the EU promulgated the "waste electrical and electronic equipment (WEEE)" and "disable hazardous substances in electrical and electronic equipment (RoHS) directive two" 9, further limiting the use of halogen flame retardant. Therefore, it is an indisputable fact that halogen free environment friendly flame retardant materials and products are used. At present, more and more use of flame retardant materials in environmental safety and the use of non-toxic and harmless inorganic flame retardants and organic phosphorus flame retardant safety.
The inorganic flame retardant is mainly used aluminum hydroxide and magnesium hydroxide (alumina trihydrate). In the epoxy resin through combustion, decomposition, combustion heat transfer and oxygen dilution, thereby interrupting the combustion, play flame retardant effect, has no halogen, non-toxic, smoke suppression and cheap, in addition, catalytic polymer produced CO into CO210. However, a large amount of additives are needed to improve the mechanical properties of the materials.

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.
In nineteenth Century the development of nanotechnology has brought the gospel to the metal hydroxide, at the same time people found that inorganic flame retardant particle size has a direct influence on the flame retardant properties. In order to overcome the shortcomings of metal hydroxide flame retardants and play their advantages, metal hydroxide flame retardants began to develop to ultra fine in recent years. Ultra fine while reducing the amount of flame retardant metal hydroxide flame retardant, but also to the process of super fine industrial production improves the corresponding cost.
The flame retardancy of carbon fiber reinforced epoxy resin was investigated by Daniela K? Nnicke and 13, respectively, of micron and nano particle size aluminum hydroxide (ATH). The study found that: the particle size reduction can improve the flame retardant effect of ATH; when the mass fraction of ATH was 20%, compared to the pure epoxy resin heat release was reduced by 11%, compared with the carbon fiber reinforced epoxy resin heat release decreased up to 38%.
Wang Xinlong 14 synthesis of 9,10- two hydrogen -9- oxa phosphaphenanthrene -10- -10- oxide (DOPO), and that the reaction of DOPO and epoxy resin epoxy resin flame retardant was synthesized, and aluminum hydroxide and nano (ATH) epoxy resin / nano ath composite was prepared. The results show that the char yield is 15.73% and the oxygen index is 24% at 700 C, which shows that the flame retardant effect is good.
With the increasing awareness of environment protection, people require flame retardant with flame retardant performance, the release of toxic gases and smoke less, but more damage to the advantages of various flame retardant material performance etc.. Especially the trend of non halogenated flame retardant materials to traditional flame retardants is facing serious challenges, which provides good opportunities for the development of flame retardant, so it has become a research hotspot in the field of flame retardant since 1990s.
Developed three phosphoric acid phenyl ester, phosphate ester and butyl cresol three phosphoric acid three commonly used plasticizer and has good flame retardant effect of phosphate of many varieties of very wide application, but most phosphate is liquid, has poor heat resistance, play, compatibility is not ideal shortcomings. Therefore, the development of high molecular weight condensed phosphate is one of the development directions of phosphorus flame retardants. Most of the flame retardants are phenolic phosphate, phosphine oxide and phosphonate ester.
