The synergistic effect of flame retardant
Two or more different flame retardants of different flame retardant mechanisms are combined to prevent combustion as a synergistic effect of flame retardants.
The synergistic effect of flame retardants 1, EPDM, 100; Decabromodiphenyl ether, 75 copies; Aluminum hydroxide, 30 copies; Sb2O3, 15 copies; DCP, 4 copies; 15 other coordination agents. In this way, the flame retardant effect is good, and the self-extinguishing time is 1s. This is because the ten pbdes and antimony trioxide reaction SbBr3, under the combustion temperature, its curbing the spread of the combustion heat and cooling effect, played the air at the same time, promote the carbonation, reduce the burning ability; The water absorbed by the decomposition of aluminum hydroxide at the burning temperature absorbs a lot of heat and cools the combustion system. This good flame retardant effect is the performance of the synergistic effect of three kinds of flame retardants.
Flame retardant synergistic effect of case 2, zinc borate and aluminum hydroxide under the condition of high temperature chemical reaction, generate a porous hard agglomerate, was conducted in the condensed phase or solid phase reaction, thus effectively prevent the rubber further decomposition of solid phase, cut off the production of combustible material, also the isolation air at the same time, the flame is extinguished, stopped burning. The combination of zinc borate and antimony trioxide, zinc borate and chlorine-containing flame retardants can produce certain flame retardant synergies, and have good flame retardant effects.
The flame retardant effect has two indicators: (1) self-extinguishing. The shorter the time of self-extinguishing, the better the flame retardant effect, the unit of self-extinguishing time, usually expressed in seconds. (2) oxygen index. The oxygen index is the percentage of oxygen that is needed to burn things. It is divided into the limit oxygen index (LOI) and the critical oxygen index (COI), and the flame retardant effect is generally expressed in LOI.
The conical calorimeter method is used to determine the flammability of rubber and is established by the international standard and technical association. The content has ignition timing, heat dissipation rate, total heat dissipation, loss rate, combustion heat and quantity of smoke. This method can also characterize flame retardant properties.
Flame retardant is one of the processing AIDS of rubber and other high polymer materials, which can make rubber and other high polymer materials have incombustible properties
Self-extinguishing. According to the use of flame retardant, the method can be divided into two types: additive flame retardant and reactive flame retardant. In rubber and other materials, most use additive flame retardant. This kind of flame retardant can be divided into inorganic flame retardant and organic flame retardant according to chemical structure.

Isopropylphenyl Phosphate(IPPP35) Use
The Product Is Used For Rubber Products And PVC Plastic Flame Retardant Conveyor Belt, Cable, Chloroprene Rubber, Rubber And Other Synthetic Rubber Flame Retardant Plasticizer, Isopropylphenyl Phosphate Flame Retardant IPPP35 Use Also Applies To Fabric Coating, Circuit Boards, Flooring, Textiles, PVC, Phenolic Resin, And Other Fields.
Isopropylphenyl Phosphate Flame Retardant IPPP35 Halogen-Free Phosphate Flame Retardant Plasticizer, Which Does Not Pollute The Environment Twice. It Is The Lowest In The Phosphate Species And Has The Highest Phosphorus Content. 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.
Inorganic flame retardants: flame retardants that can break down water and cool down: aluminum hydroxide [Al(OH) 3], magnesium hydroxide [Mg(OH2)] etc. Flame retardants that can decompose carbon dioxide and isolate oxygen: NaHCO3, potassium carbonate (KHCO3), copper carbonate (CuCO3), magnesium carbonate [Mg(HCO3)2] etc. Other inorganic compounds: zinc borate, antimony trioxide, ammonium chloride, ammonium bromide, iodine, red phosphorus, potassium chloroplatinate, etc.
Organic flame retardant: it is a brominated organic compound with decabromodiphenyl ether, which is both additive and reactive flame retardant. The ability of halogen flame retardants is listed in the following order: iodine > bromide > chloride > fluoride.
Phosphorous flame retardants: trimethylphenol phosphate, trioctyl phosphate, tri-butyl oxyethyl phosphate, cresol diphenyl phosphate, triphenyl phosphate ester, etc. Chlorophosphate: three (22 chloroethyl) phosphate, 3 (22 chloropropyl) phosphate and 3 (1, 32 dichloropropyl) phosphate. These flame retardants are suitable for polyurethane sponges. Dichloroprene new pentyl glycol phosphate acrylate is suitable for acrylate rubber. Molecular formula C14H11Cl10PO4, perchlorophosphate flame retardant, suitable for CR, SBR2IIR.
These flame retardants are suitable for ethylene propylene rubber. Nitrogen phosphate: (ho-ch2-ch -) 2n-ch2-opo - (o-c2h5) 2 polyphosphate and polyphosphate, suitable for polyurethane rubber.
Phosphoric acid amide, polyphosphoamide flame retardant, arylamide, dimethyl phosphate, are suitable for all kinds of rubber. 3 (2, 32 dibromopropyl) is a common flame retardant in the world market.
Other flame retardants: metformin and 52-phenyltetrazole can decompose nitrogen at high temperature, which can be used to isolate the flame to isolate the flame retardant of oxygen and fuel. Chlorinated paraffin 270 is a commonly used and inexpensive flame retardant.
