Halogen flame retardants for polypropylene (PP)
Halogen flame retardant (PP) for polypropylene (PP) has little amount of added and flame retardant effect. It occupies an important position in the field of flame retardant. The combustion of PP is prevented mainly by the synergistic effect of flame retardants and flame retardants, such as Sb2O3, to suppress gaseous combustion reactions.
The commonly used polypropylene (PP) with halogenated flame retardants, decabromodiphenyl oxide with eight bromo ether, bisphenol A, four bromo six bromo alkyl ring twelve, with the largest amount of decabromodiphenyl oxide. Organic halide is PP traditional flame retardant, halogen Sb2O3 flame retardant system has good flame retardant effect, but it produces large amount of smoke when burning, and produces a large number of corrosive and toxic gases. Halogen flame retardants used in polypropylene (PP) are often combined with other flame retardants to give full play to the flame retardant effect.
Synergistic effect of composite flame retardant can be achieved by blending halogen flame retardant and inorganic flame retardant in polypropylene (PP). PP PE copolymer was filled with a mixture of Mg (OH) 2 and Sb2O3 (Br Sb) with mass ratio of 1:1, Br Sb limited the strong exothermic phenomenon after ignition, and the combination of Mg (OH) 2 and Br Sb made the flame retardancy of Br Sb move to high temperature, and improved the thermal stability and flame retardancy of the polymer. Adding brominated acrylic acid, Sb2O3 (Sb Br) and Mg (OH) 2 to glass fiber reinforced PP can give the flame retardant properties of the material. Brominated monomers not only react with PP, but also react with glass fiber and Sb2O3 particles; brominated acrylic acid can improve the flame retardancy of PP, and the reaction of brominated acrylic acid and Sb2O3 also enhances the flame retardancy of PP.
Yu Li (FR10) of decabromodiphenyl oxide and Sb2O3, with the use of red phosphorus flame retardant and mechanical properties of EPDM PP, FR10 and Sb2O3 and FR10 in EPDM PP and red phosphorus and have synergistic effect of flame retardant, red phosphorus and FR10 and FR10 and Sb2O3 ratio and good flame retardant effect.
Halogen flame retardants (PP) used as one of the most important organic flame retardants are one of the most popular flame retardants. Because of its low price, good stability, little amount of addition, good compatibility with synthetic resin materials, and keeping the original physical and chemical properties of flame retardant products, it is the largest organic flame retardant in the world.
Halogenated flame retardants (HX) are decomposed by halogenated flame retardants (PP) in polypropylene (PP), and hydrogen halides can eliminate reactive radicals produced by combustion reactions of polymers. Such as HX and flame chain reaction active substance HO??, so that the above free radical concentration decreased, thereby slowing or terminating the burning chain reaction, to achieve the purpose of flame retardant.
Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP)
(A Small Cabinet Loaded With 16 Tons), 1000KG / IB Bucket (A Small Cabinet Installed 18 Tons) Or 23 Tons (1, 3-Dichloro-2-Propyl) Phosphate (TDCPP) Packing: Net Weight 200KG / ISOTANK.
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.
Silicon containing compounds have obvious flame retardant effects on polymers. They can not only concentrate carbon dioxide, but also capture free radicals in the gas phase. Compared with other flame retardants, they can greatly reduce the environmental pollution and are considered as environmentally friendly flame retardant materials. In recent years, the research on silicon flame retardants has become a new hot spot.
Silicone flame retardant inorganic and silicone flame retardant, silicone flame retardant flame retardant effect is better than non model, and PP miscibility is good, is the main development direction of silicon flame retardant.
Silicone flame retardant has both organic and inorganic advantages, with moisture resistance, water, electrical insulation, high and low temperature, chemical stability and other excellent performance. Silicone flame retardant can not only improve the flame retardancy and smoke suppression of PP, but also improve the mechanical and electrical properties of the material.
SFR1000 can improve the impact resistance, melting, processability, surface gloss and color of PP at room temperature and low temperature. DCRM47105 and 47081 added 0.1%~10% can improve its processability; adding 1%~8% can obtain flame retardant PP with low smoke content, heat release and CO production.
Flame retardant mechanism of organosilicon compound system of silicon carbide coking isolation layer is generated for the vinyl organic silicate to prevent oxygen, internal plastic and air in contact and transfer, inhibiting the release of toxic gases and smoke generation, so as to improve the flame retardant and smoke suppression effect.
Inorganic silicon compounds can form a synergistic system with IFR, and PP APP PER system mixed with SiO2 is the best synergistic system, with the highest LOI up to 35.5%, higher than pure PP17%.
Silicon tungsten compounds are effective catalysts for phosphorus nitrogen based flame retardant, silicotungstic acid (SiW12) as a catalyst in phosphorus nitrogen based expansion synergistic effect of flame retardant, phosphoric acid and its derivatives can be induced to produce more high yield under high temperature; silicotungstic acid amount (1.5%) at high temperature by increasing LOI and thermal stability intumescent flame retardant additives and AM to enhance collaborative effect, promote the formation of coke structure on the surface of PP combustion, TGA (thermogravimetric analysis) data show that SiW12 makes the PP IFR system has very high thermal stable temperature (> 500).
