Phosphoric acid ester flame retardant
In recent years, the variety of phosphatide flame retardants is much lower than that of phosphonates, most of which are used in antioxidants, stabilizers and anti-aging agents, and are used in fewer flame retardants.
In 1991, Renner reported an annular phosphite ester by vertical burning test showed that the flame retardant performance can be achieved (UL - 94), V - 0, its flame retardant effect is good, is mainly due to the pentaerythritol skeleton in polymer can form a layer of protective film to coke burning. The flame retardant of phosphatate is the new research direction.
Recently developed a new type of polyether polyols and phosphorous acid ester (phosphine) in the application of polyurethane soft foam test results show that it is a kind of high thermal stability, flame retardant effect is good, at the same time with plasticizer and antioxidant properties, the new type of phosphate ester flame retardant.
Salt is a phosphor organic compound with R4PX structure. The representative variety is tetrahydroxymethyl chloride (THPC), which is an early development of fabric flame retardant. It is made of hydrogen phosphate, formaldehyde and hydrochloric acid.
THPC belongs to reactive flame retardant, which can react with the reactive group of cotton fiber. The products are the components of the treated object, thus the flame retardant performance is durable and the washing resistance is good. But because of the possible carcinogenic chloromethyl ether during manufacture or use, it is rarely used. To this end, people have carried on the modification research, has developed the replacement product. Cyanard rf-1, developed by Cyanamide of the United States, can maintain the strength and softness of the fiber, which can be used for flame retardant treatment of cotton cloth and anti-rain cloth. The phosphonate is a new generation of phosphorus flame retardant developed in recent years, and the flame retardant of phosphonate is used in the flame retardant of thermoplastics (such as PA, PBT), fiber and textiles.
At present, the most widely used phosphors are phosphate and phosphonates and their halogen derivatives (including their odes). Phosphate flame retardant is an important series of flame retardants of organophosphorus system. It has both flame retardant and plasticized effect, so it is increasingly valued and the proportion of flame retardant is increasing.
Isopropylphenyl Phosphate(IPPP50)Use:
Isopropylphenyl Phosphate, Flame Retardant IPPP50 This Product Is Compatible With Vinyl Chloride, Nitrocellulose, Synthetic Resin And Natural Resin, Etc. Because Of The Above Advantages, Reofos Series In Industrial Production Is Widely Used: PVC Film As Flame Retardant Plasticizer, Reofos Increase In The Amount Of Oxygen Index Increased, Enhanced Flame Retardant. In The Rubber Industry Can Be Used As Chloroprene Rubber And Rubber Flame Retardant Plasticizer; In Other Industries Can Be Used As Lubricants With Extreme Pressure Additives And Digestion Of Cellulose Paint, Resin, Phenol Resin And Other Flame Retardants.
Isopropylphenyl Phosphate, Flame Retardant IPPP50 Use Is Also Applicable To Fabric Coating, Circuit Boards, Flooring, Textiles, PVC, Phenolic Resin And Other Fields.
Most of the flame retardant is solid, its common defect is lowered the physical - mechanical properties of materials, in addition to make some plastic film, synthetic fiber become transparent or colored, liquid flame retardants, must be followed by appropriate organic of aryl and alkyl phosphate ester, it is the ideal that accords with a requirement of flame retardants. Adding them to such resin as PVC and PE not only makes the resin flame retardant, but also gives it excellent plasticity.
But as additive flame retardant, single phosphate into liquid commonly, because of its low molecular weight, low vapor pressure, high decomposition temperature, thermal stability is poor, so easy volatile, decomposition process for plastic processing, and damaged the flame retardant performance, flame retardant both poor durability, and the pollution of plastic processing environment, and the mechanical properties of the low molecular weight also make plastic products affected by large, these have hindered the phosphate ester flame retardant in the processing of high temperature engineering plastics and its application need resistant durable flame retardant plastic products.
Since the 1990 s, with development of further research of flame retardants, phosphate flame retardants, phosphate from a single class to get together or double phosphate ester flame retardant transition, especially double poly phosphate is also called low poly phosphate, with the appropriate molecular weight, low steam concurrently at the same time, small mobility, good durability, low toxicity, colourless, odourless, hydrolysis resistance and other advantages, and is widely used in PU, ABS, PC, PET, SAN, PP material such as flame retardant.
Phosphate ester flame retardant effect of oligomer is better than small molecule flame retardants, durable longer and theoretically analysis may be due to compared with small molecular phosphate flame retardants, phosphate ester oligomer molecular weight is bigger, and the resin has good intermiscibility, its volatile small, thus can keep for a long time in the system, give full play to the flame retardant efficiency of condensed phase. For example, polyphenol bidiphenyl phosphate RDP is used to flame retarded HDPE.
The contribution of phosphorus to HDPE index can be 1.3 to 4 times of halogenous antimony system. In addition, with the increase of the molecular weight of phosphatate, they improve the efficiency of HDPE oxygen index. In terms of transparency, smoke and environmental factors, the phosphorus content is more promising than halogen.
