Common nylon flame retardant
Nylon can be flame retarded by halogen/antimony or other flame retardant synergistic systems, or it can be flame retarded with a halogen free flame retardant system with red phosphorus or melamine. In terms of quantity, the synergistic system of halogen/antimony is still the most widely used nylon flame retardant system. In some parts of Europe and Asia, people are looking for alternatives to halogen flame retardants.
But generally speaking these alternative systems generally have low thermal stability or moisture absorption problems. For red phosphorus, there are also storage problems, because they are flammable. Here are a few common nylon flame retardants and their respective strengths and weaknesses.
Common nylon flame retardant containing halogen flame retardant system (1) : the most important of which is also one of the most widely used abroad is the styrene brominated polymer, it has extremely excellent thermal stability, and because it is melting can be mixed with nylon, therefore in the process of processing has good liquidity.
In addition, the flame retardant nylon prepared with it has superior electrical performance and better physical mechanical properties. The limitation of this flame retardant is poor in light stability and is not fully compatible with nylon. In addition, the cost is higher than that of the ten brominated diphenyl ether which is widely used in China.
Another application for many years in nylon flame retardant is flammable, it is a kind of chlorine flame retardant, high flame retardant efficiency and performance, but its limitations in the thermal stability of applies only to the lower processing temperature nylon flame retardant system. At present, the most widely used flame retardant in China is decocbromide, which is the most economical flame retardant due to its high bromine content and high flame retardant efficiency for nylon. But since it is a type of filler flame retardant, it has a great negative effect on the physical mechanical properties of the processing fluidity and the products.
In addition, its thermal stability and light stability also teach poor. In recent years, people have developed in the aspect of flame retardant nylon used as follows: a new flame retardant is 10 phenoxy ethane, it with bromine content in ten bromine biphenyl ether has the same and the same high flame retardant efficiency, and with styrene brominated polymer as no (the so-called second evil).
In addition, it has good thermal stability and light stability. Its limitation is that it is similar to the same type of packing type flame retardant as decabromoether, which is poor in compatibility with the polymer, so the physical mechanical properties of the processed fluidity and products are poor. In addition, the cost is higher than that of PBBR.
Common nylon flame retardant (2) no halogen flame retardant system: the widely used halogen free flame retardant in nylon is red phosphorus and melamine salt. Red phosphorus flame retardant efficiency and improve product has a very high arc resistance, but its storage and color limitations greatly limits its application in nylon, typically used in nylon 6.
Tert Benzyl diphenyl phosphate (BPDP-71B) basic information
Chinese name t - butyl phthalate diphenyl phosphate
(1,1-dimethylethyl) phenyl diphenyl phosphate; t-butylbenzene diphenyl phosphate (MDPP); tert-butylated triphenyl phosphate 71B)
English name tert-Butylphenyl diphenyl phosphate
English name: Tert-Butylphenyl Diphenyl Phosphate; T-BUTYLPHENYL DIPHENYL PHOSPHATE; Phosphoric Acid (1,1-Dimethylethyl) PhenylDiphenylEster; Arylphosphates; Tetrabutylphenyldiphenylphosphate; BPDP; PARA-TERT-BUTYLPHENYLDIPHENYLPHOSPHATE; Tert.-Butylphenyldiphenylphosphate
Molecular formula: C22H23O4P
Molecular weight 382.39
EINECS 260-391-0
Tert Benzyl diphenyl phosphate (BPDP-71B) use
Tert-butyl phosphate diphenyl phosphate, tert-butylated triphenyl phosphate is halogen-free organophosphorus flame retardant, using a new, excellent performance of phosphorus flame retardant, with excellent thermal stability and hydrolysis Sex. Its high thermal stability makes it as an engineering plastic flame retardant at the same time, can improve the plastic melting performance. Tert-butylated triphenyl phosphate for the liquid, in the resin can make its durability and hydrolysis stability is better, and easy to produce the table and stress cracking. It is widely used in flame retardant PV (, cellulose resin, into the rubber, phenolic resin, epoxy resin, polyene unit fiber.
Another halogen free flame retardant used in nylon is melamine, which is mainly melamine and phosphate. They have good flame retardant efficiency, but the thermal stability is poor, and because of the high moisture absorption, the product has poor performance in humid environment.
Main factors affecting the effect of flame retardant nylon:
First, the selection of flame retardants is selected for different occasions and requirements.
Second, the dosage of the flame retardant and coordinated effect if choose a single flame retardant, flame retardant effect of red phosphorus and bromine series flame retardant is better, when the dosage of red phosphorus is 5% ~ 7%, bromine flame retardants dosage is 15% ~ 17%, the nylon vertical combustion can reach V - level 0; The flame retardant of nitrogen can only make the nylon vertical combustion grade to V- 2.
If three kinds of flame retardants are used together, their dosage is reduced, and the effect is more obvious.
