Flame retardant for ABS engineering plastics
The flame retardant of ABS engineering plastics has the advantages of large molecular structure, white appearance, excellent light resistance, good thermal stability and excellent light resistance. The flame retardancy of ABS engineering plastics is better than that of common flame retardants because of its synergistic effect of flame retardancy.
Flame retardant flame retardant ABS engineering plastics used in ABS, HIPS, PS, PC, PC/ABS, PBT, PET, PE, PVC engineering plastics modification, add less has the characteristics of good flame retardant effect, while using Sb2O3 to use in general.
ABS engineering plastics flame retardant engineering plastics can be used in a variety of injection molding and extrusion occasions, to meet a variety of processing requirements, flame retardant recycling can be recycled processing and reuse.
In three 2,4,6 were three triazine flame retardant modified products have the following characteristics: (1) effects of coloring wrong products, if only use the flame retardant can be made of transparent products; (2) add less. Because of the high bromine content of flame retardant resin, with good solubility, uniform dispersion, high flame retardant efficiency; (3) good processing: no foaming, liquidity and thermal stability, excellent, excellent dispersion, surface finish products; (4) good mechanical properties: mechanical tensile, bending and impact etc. excellent performance; (5) migration resistance, no precipitation, no escaping; (6) products, good UV resistance and weatherability, excellent resistance to yellowing; (7) products, excellent heat aging properties, processing cycle 6 times, its mechanical properties remained unchanged; (8) combustion does not produce dioxin / two benzofuran (PBDD/PBDF), namely: it fully complies with the regulations of dioxin in Germany and 40766.25 final regulations EPA TSCA.
Among the TBP not only can be used as reactive flame retardant epoxy resin and polyurethane resin, intermediate brominated polyphenylene ether, phosphite, phosphate and other new high performance flame retardant, and can be used as wood, paper and other preservatives, can also be used as a group of compound flame retardant for other resins, also can 2,6- two poly PBBs prepared by polycondensation of flame retardant, the compounds are widely used in nylon 66, high impact polystyrene, ABS resin, thermoplastic polyester and modified polyphenylene ether for engineering plastics. It has a wide range of applications.
Abroad, TBP is mainly used as the raw material of flame retardants. Because of the harm of polybrominated diphenyl ethers (two phenyl ethers) to humans and the environment, western developed countries used many new brominated flame retardants instead of polybrominated diphenyl ethers two years ago. Brominated epoxy oligomers are among the top substitutes for repair products. The specific approach is to end epoxy with TBP blocking brominated epoxy oligomer, metal adhesion so that the epoxy becomes weak, membranous changes, and bromine content increased by about 10%, so it can not only reduce the amount of fire retardant, can also improve the impact resistance.
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.
Based on these advantages, the demand for TBP international market is increasing rapidly. In Japan, for example, in the early 1990s, the demand for TBP increased exponentially, with demand exceeding 4000 tons in 1994, and demand exceeding 7000 tons in 2000, and its domestic import from the United States and Western europe.
In China, with the continuous expansion of the scale of industrial production of bromine, brominated flame retardants have full production conditions. And, with the rise of the domestic manufacturing industry, and the Ministry of Public Security issued "performance requirements and marking" standard combustion flame retardant products in public places and the "Fire Law" the implementation of brominated flame retardant consumption will show good momentum.
In addition, as the production of 2,4,6- three were three triazine flame retardant intermediates and fine chemical intermediates 2,4,6- tribromophenol is a great potential for development, with the rapid development of China's synthetic resin industry and pharmaceutical industry, domestic demand will be more and more.
Liu Xin et al. Studied the influence of intumescent flame retardant system composed of ammonium polyphosphate / melamine / pentaerythritol (APP/MEL/PER) intumescent flame retardant system and nano magnesium hydroxide (MH) on the flame retardancy of EP. The study found that: the addition of MH in intumescent flame retardant system can improve the limiting oxygen index EP (LOI), when the mass fraction of IFR is 16%, the mass fraction of MH is 4% EP, the LOI value reaches 28%, better than the single addition of IFR.
Thermogravimetric analysis showed that MH could retard the pyrolysis tendency of intumescent flame retardant EP, and promote the char formation process of IFR to some extent, and increase the residual carbon rate of intumescent flame retardant EP.
Zheng Xiaolong and other bisphenol A- bis (phosphate two phenyl ester) (BDP) were prepared with ammonium polyphosphate and nano silica respectively to prepare new halogen free flame retardant epoxy resin (EP) material. It is found that BDP monomer can improve the flame retardancy of epoxy resin. When the addition of BDP is 15%, the oxygen index of the material increases from 25% to 29%. On the basis of BDP monomer flame retardant, the oxygen index of the system increases to 29.9% and 30.4% respectively after adding 9% APP and 5% nanometer SiO2 respectively, and the vertical combustion reaches V-0 grade.
