Resistant to transfer of bromine and nitrogen
2 minus 2 - three triazine flame retardants (FR368) containing bromine, nitrogen migration resistance of flame retardant, its molecular structure is big, white appearance, excellent light resistance, resistance to overcome the ten bromine biphenyl ether color hair is yellow, the shortcomings of poor light resistance. Good thermal stability, excellent light resistance.
Due to the synergistic effect of bromine and nitrogen, the flame retardant ratio is better than that of decoction. Migration resistance containing bromine, nitrogen flame retardants suitable for ABS, HIPS, PS, PC, PC/ABS, PBT, PET, PE, PVC flame retardant modification of engineering plastics, has many characteristics, such as adding quantity is little good flame retardant effect, use in general need to be used at the same time Sb2O3.
Flame retardant engineering plastics containing bromine and nitrogen can be used in various injection molding and extrusion occasions to meet various processing requirements, and the flame retardant recycling can be recycled and reused.
The products with 2,4, 6-tri-triazine flame retardant have the following characteristics:
(1) it has no influence on the coloring of the products. If the flame retardant is used alone, the transparent products can be made.
(2) little addition. Because the flame retardant bromine content is high, it is good with the resin, dispersing evenly and the flame retardant efficiency is high;
(3) good processing: no foaming, excellent fluidity, excellent stability of heat and stability, dispersion of excellent, clean surface of products;
(4) good mechanical properties: excellent mechanical properties of stretching, bending and impact;
(5) resistant to migration, not precipitate out or escape;
(6) product weatherability, uv resistance, and yellow resistance;
(7) the thermal aging performance of the products is excellent, and the cycle processing is 6 times, and its mechanical properties are basically unchanged.
(8) it does not produce dioxin/dibenzofuran (PBDD/PBDF) after combustion, i.e., it fully meets the requirements of German dioxins and EPA TSCA 40 766.25 final regulations.
Isopropylphenyl Phosphate(IPPP95) Use:
Isopropylphenyl Phosphate, Flame Retardant IPPP95 Is Used For Rubber Products And PVC Plastic Flame Retardant Conveyor Belt, Cable, Chloroprene Rubber, Nitrile Rubber And Other Synthetic Rubber Flame Retardant Plasticizer, Triisopropyl Phenyl Phosphate Applicable To Fabric Coating, Circuit Boards, Flooring, Textiles, PVC, Phenolic Resin And Other Fields.
Isopropylphenyl Phosphate, Flame Retardant IPPP95 Halogen-Free Phosphate Flame Retardant Plasticizer, Will Not Twice Pollute The Environment; In The Phosphate Ester Species Is A Viscosity, Phosphorus Content Is More Moderate A Model. This Product Is Colorless And Transparent, Good Compatibility, The Use Of Both Flame Retardant And Plasticizer, In The Flame Retardant And Plasticizer To Play A Balance Between The Role, But Also To Make The Processing Of The Same Material And Its Physical Properties.
Body between the TBP not only can be used as the reaction of epoxy resin and polyurethane resin type flame retardants, bromine and polyphenyl ether, phosphite ester, phosphate and other new type of high performance flame retardant intermediates, and can be used as a preservative for wood, paper, and also can be used as the complex matches a component of flame retardants used in other resin, can also by polycondensation method into a new type of flame retardant poly (2, 6-2 bromobenzene ether, this compound is widely used in nylon 66, high impact polystyrene, ABS resin, thermoplastic polyester, and modified polyphenyl ether wait for engineering plastics. There are quite a few applications.
In foreign countries, TBP is mainly used as the raw material for flame retardant. Because of worries about the dangers of polybromodiphenyl ether to humans and the environment, developed countries in the west have used some new brominated flame retardants to replace polybromodiphenyl ether many years ago. In the forefront of the replacement repair products are epoxides bromide epoxides. Its particular way is blocked by the TBP brominated epoxy oligomer at the end of the epoxy group, which makes metal adhesion of epoxy group, membranous better off, and bromine content increased by about 10%, therefore, not only can reduce the dosage of flame retardant, still can improve the resistance to impact.
Besides as production 2 minus 2-3 are triazine flame retardant intermediate 2 minus 2 - three bromine phenol is a kind of great potential for development of fine chemical intermediates, along with the rapid development of China synthetic resin industry and medicine industry, domestic demand will be greater and greater.
Liu xin et al. studied the influence of the compound flame retardant system composed of ammonium polyphosphate/melamine/pentaerythritol (APP/MEL/PER) and magnesium hydroxide (MH) on EP flame retardation performance. Study found that by adding a expansion flame retardant system of MH can improve the limit oxygen index (LOI) of EP, when IFR mass fraction is 16%, the mass fraction of MH was 4%, the LOI value of EP reached 28%, than add IFR increased. The heat weight results show that MH can delay the pyrolysis trend of the expansion flame retardant EP and promote the carbonation process of IFR to some extent, and increase the residual carbon rate of the expansion flame retardant EP.
The new halogen-free flame retardant epoxy resin (EP) material was prepared with polyphosphate (BDP) and polyphosphate (BDP) respectively.
The study found that BDP monomers were able to improve the flame retardant performance of epoxy resin. When the amount of BDP was 15%, the material oxygen index increased from 25% to 29%. On the basis of BDP monomer fire retardation, the oxygen index of the system increased to 29.9% and 30.4% respectively after adding 9% APP and 5% nano-sio2 respectively, and the vertical combustion reached v-0.
