Flame retardant for engineering plastic products
The flame retardants used in engineering plastics are mainly polybrominated biphenyls (PBB) and polybrominated benzene ether (PBDE), which represent more than 85% of the Chinese market.
Appeared in the field of flame retardant in recent years polybrominated diphenyl ether flame retardant toxicity and environmental issues of dispute, the European Union in 2003 the harmful materials in the electronic motor disable directive (RoHS ban), decided to a total ban on July 1, 2006 PBB, PBDE bromine flame retarding agent used, etc.
The reason is that halogen flame retardants cannot be recycled, and the burning and heating process will release harmful substances that threaten the health, environment and future generations of human beings. Other countries have followed suit, leading to a cautious approach to the use of bromine flame retardants in high polymers by manufacturers of flame retardant materials.
On February 28, 2006, the "China RoHS", known as "the control of electronic information product pollution control", was promulgated and implemented on March 1, 2007. The management measures explicitly listed six toxic and hazardous substances, such as lead, mercury, cadmium, hexavalent chromium and polybrominated diphenyl ether, in electronic products.
In order to deal with the RoHS ban engineering plastic products, the flame retardant is urgently needed to develop new products. Currently there are three main kinds of thinking, one is to develop the phosphorus-containing flame retardants, more for phosphate ester, but this kind of engineering plastics products used in flame retardant products less, the price is high, influence the performance of plastic processing, application is restricted in the field of engineering plastics; Second, the development of inorganic flame retardants, such products are mainly Mg (OH) 2 and Al (OH) 3 is given priority to, its characteristic is the dosage, effect on product performance, some is not applicable to high-end products, its dispersion issue could not be a good solution; The structure of the three is to develop other phosphorus-containing flame retardant, has become A hotspot of research and development, has been widely used with hexabromocyclododecane, tetrabromobisphenol A, etc., domestic production capacity has reached 100000 tons, the two types of product defect is the synthesis of flame retardant plastics has not migration resistance, do not reuse, relatively heavy pollution to the environment.
In foreign countries, tribromophenol (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. One of the most important substitutes for alternate alternate products is the bromide epoxy oligopolymer.
Isopropylphenyl Phosphate(IPPP95)
Traits: Colorless Or Light Yellow Transparent Liquid
Acid Value (MgKOH / G): 0.1 MgKOH / G Max
Flash Point Flash Point: 220 ℃ MIN
Viscosity Viscosity (25 ° C): 67 ± 2 CPS
Acid Value (MgKOH / G): 0.1 MAX
Refractive Index Refractive Index (N23): 1.546-1.555
Color Color: ≤ 95
Moisture% Water Content: 0.1% MAX
Phosphate Content: BY 7.6%
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.
Its particular way is to use three bromine phenol to blockade the end of the brominated epoxy oligomer 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, can also improve the resistance to impact. Based on these advantages, the international market demand of tribromophenol is increasing rapidly.
When the color of products, add quantity is little, good intermiscibility with resin, flame retardant, high efficiency, good processability, product recycling and after combustion does not produce dioxins / 2 coumarone (PBDD/PBDF), comply with the eu's dioxin regulations and EPA TSCA 40 766.25 final regulatory requirements, as environmentally friendly flame retardant.
The flame retardant industry has developed rapidly in recent years, with more than 75% of it being used in engineering plastics. The products are mainly used for flame retardant modification of engineering plastics in electronics, electric appliances, electromechanical, telecommunication, textile, automobile, machinery, sports and leisure products etc.
With the growth of awareness of environmental protection, people require flame retardants have flame retardant performance optimization, the release of toxic gas and smoke less, but more damage is used by various flame retardant base material performance, etc. Especially no halogenated flame retardant material trend make traditional flame retardants is facing severe challenges, this is for the development of phosphorous flame retardants provides a good opportunity, make it since the 1990 s, one of the hot research topic in the field of flame retardant.
Developed triphenyl phosphate, tricresol phosphate ester and plasticizer tributyl phosphate and other commonly used and has a good flame retardant effect of phosphate variety many, the application is very wide, but most of the phosphate ester as a liquid, heat resistance is poor, play big disadvantages, compatibility is not perfect. The development of high molecular weight polyphosphate is one of the development directions of phosphorus flame retardant. Most of these flame retardants are phenolic phosphate, phosphine and phosphonate.
