2017-11-20 11:39:21
Halogen free flame retardant for epoxy resin is a kind of high performance phosphorus and nitrogen organic flame retardant. It is a kind of three triazine three ketone compound and three triazine three amine compound. After special surface treatment, it is easy to disperse and not precipitate in plastic material, and has good flame retardant effect. The halogen free flame retardant for epoxy resin is decomposed at a temperature of about 450 degrees, and the maximum particle size (D50%) is 20/um. The appearance is white powder. It is a high performance halogen free flame retardant which does not affect the color of the product.
Recommended for polyamide (nylon) widely used in epoxy resin, polyurethane, polystyrene, polyester (PET, PBT), polyolefin and halogen free wire and cable, it is recommended to add 15%-30% halogen free flame retardant W666, 94UL can reach the V0-V2 standard.
Flame retardants are also called flame retardants, fire retardants or fire retardants: flame retardants give flammable polymers flame retardant functional auxiliaries; flame retardants are divided into additive flame retardants and reactive flame retardants in accordance with the application mode. Additive flame retardant is directly mixed with resin or rubber, flame retardant is easy to process, adapt to a wide range, the main body of flame retardant.
Reactive flame retardants are often used as monomers to bond to polymer chains. Flame retardants have little effect on the properties of the products, and the flame retardant effect is durable. According to the composition of flame retardant, flame retardants mainly include inorganic flame retardant, halogenated flame retardants (organic chloride and organic bromide), flame retardant (red phosphorus, phosphate and Halogenated Phosphate etc.) and nitrogen flame retardant etc..
Reactive flame retardants are mostly organic halogen flame retardants containing reactive functional groups and monomers of organophosphorus flame retardants. In addition, the flame retardant molybdenum compounds, tin compounds and iron compounds, such as smoke suppression, also belong to the category of flame retardants.
Phosphazene compounds with P and N double bond is a kind of alternate arrangement of inorganic compounds exist in the chain structure, circular or linear structure on the phosphorus atom access phenoxy that the product introduction, phenoxy phosphazene compounds become the product of the combination of inorganic compounds and organic compounds, is a kind of good halogen-free environment-friendly flame retardant.
Because of the synergistic effect between phosphorus and nitrogen, the nitrile flame retardant has high thermal decomposition temperature and flame retardant effect, and has less smoke and toxic gas. An environment-friendly flame retardant material can meet the requirements of EU RollS directive and WEEE directive.
Performance mechanism of flame retardant phosphazene compounds for the comprehensive effect of four kinds of ways, decomposition of phosphazene heat endothermic cooling mechanism; the heat generated by the decomposition of phosphoric acid, phosphate and polyphosphate, can form a layer of protective film on the surface of polymer volatile material, cut off the air, this is the isolation membrane mechanism;
simultaneous heating after the release of carbon dioxide, ammonia, nitrogen, water vapor and other gases, this is not the dilution mechanism; combustion gas blocking the supply of oxygen to achieve synergistic and cooperative purpose, and polymer combustion PO? Group formation, it can H, HO and active groups in the flame zone with play inhibition of the flame, which is to terminate the chain reaction mechanism. Because of the synergistic effect, the system exhibits good flame retardancy.

Flame retardant TPP has many advantages, such as excellent transparency, softness, bacterial resistance, and water proof, grease-proof, good electric insulation, as well as good compatibility. Flame retardant TPP is mainly used as the flame-retardant plasticizer for cellulose resin, vinyl resin, natural rubber and synthetic rubber. And it may also be used as the flame-retardant plasticizer for glyceryl triacetate thin ester and film, rigid polyurethane foam, phenolic aldehyde resin, and PPO, etc.
Flame retardant TPP is a kind of halogen-free environment-friendly flame retardant with phosphorus element. Most of the products in the market are self-colored flaky crystal, our product is self-colored crystalline powder, and is more soluble in organic solvents. TPP is not soluble in water, but soluble in benzene, chloroform, ether and acetone, and slightly soluble in Z alcohol. Flame retardant TPP is nonflammable with slight aromatic odor and slight deliquescence. The fusion point is about 50 ℃, and fast melts to hoop-shape when heated. The lubricate effect is excellent, and it is often used as the flame retardant plasticize lubricant. What is more, it is used as the flame retardant for many plastics and resins, such as phenolic aldehyde resin, epoxy resin and so on.
Additive halogen free flame retardants are used in large scale integrated circuit packages; epoxy resin molding compounds, copper clad laminate, powder coatings, LED light-emitting tubes and other polymeric materials are flame retardant, comply with EU REACH regulations, ROHS standards. It can reach UL-94 VO grade flame retardant performance, and the flame retardant performance is much better than the traditional flame retardant system.
Halogen flame retardant is a kind of flame retardant polymer or mixture containing halogen and halogen containing flame retardant combinations, there are three main and two antimony oxide decabromodiphenyl oxide, it is often said that the bromine antimony flame retardant grade, grade bromine antimony flame retardant has excellent flame retardant properties, was used as fire retardant materials widely used.
However, when the fire occurs, such materials using halogen flame retardants produced by heating will produce a large number of smoke and toxic corrosive halogenated hydrogen gas, causing two times of harm. In February 2003, the European Union promulgated the two directives of WEEE and RoHs. WEEE is the directive on recycling waste electrical and electronic equipment. RoHS is the directive on limiting and prohibiting the use of certain toxic and harmful substances and elements in electronic and electrical equipment.
In August 2004, the two directives were translated into the laws and regulations of the 15 member states of the European union. Western Europe in the wire and cable, building materials, coatings and other industries began to implement new flame retardant classification methods and testing standards. China has also begun to approve national standards for grades of combustion of building materials and products.
The flame retardant grade and national standard of China have the same characteristics as the new standard in Western Europe, that is, to judge the flame retardant performance by emphasizing the rate of fire development, the rate of heat release, the smoke producing property and the corrosiveness and toxicity of combustion products. In order to pass this new standard, the traditional three oxidation, two antimony halogen flame retardant material will be powerless.
The new flame retardant system, when burning, the amount of smoke is small, not producing corrosive, toxic gas. Halogen free flame retardants are mainly composed of phosphorus compounds and metal hydroxide
