Polyester fiber reactive halogen free flame retardant DOPO, phenanthrene cyclic phosphate as phosphorus organic phosphorus heterocyclic compounds, with high thermal stability, oxidation resistance and excellent resistance to water, reaction type and flame retardants, mainly used for polyester fiber, polyurethane foam plastic, thermosetting resin and adhesive, because the polyester fiber reactive halogen free flame retardant phosphorus carbon bond and flame retardant properties of phosphate is better than the general.
According to experts, HQ polyester fiber reactive halogen free flame retardant is a new type of environmental phosphorus containing halogen-free flame retardant, mainly used for circuit boards and other high-grade epoxy resin, can replace the brominated flame retardant (four tetrabromobisphenol -A), can be used for packaging, printed circuit board, LED semiconductor luminous tube, for must comply with the requirements of ROHS products, for the synthesis of reactive flame retardant intermediates.

HCA polyester fiber reactive halogen free flame retardant DOPO quality index: appearance: White / flake particles; content of more than or equal to 98.5% (HPLC); melting point: 117 to 121 DEG C; chlorine content: less than or equal to 200 (PPM); P: = 14%; solubility: soluble in methanol, ethanol, chloroform, methyl two formamide, two oxygen ring. Soluble in benzene, insoluble in water and hexane.
Phosphanoid cyclic phosphate is an organophosphorus heterocyclic compound. According to the experts, it has high thermal stability, antioxidation and excellent water resistance. It is a reactive and additive flame retardant. It is mainly used for polyester fiber, polyurethane foam, thermosetting resin and adhesive. Because the flame retardant has phosphorus - carbon bond, the flame retardancy is better than that of the common phosphate.
(1) a reactive flame retardant used for epoxy resin.
The reaction of DOP with epichlorohydrin and then reacted with hydroquinone, experts said, especially the epoxy resin as the electrical insulation materials, semiconductor materials used for the sealing material, insulation, low volatile appliances, low pollution, ABS, have good compatibility, add after the formation of transparent plastic flame retardant;
(2) coloring agent
The coloring of ABS, AS, PP, PS, epoxy resin, phenolic resin, alkyd resin, surface active agent and polyurethane coloring caused by light and heat can be prevented by adding DOP.

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.
Inorganic flame retardants are an important component in the non halogen flame retardant. High performance non halogenated inorganic flame retardants can be added into polyolefin without affecting the mechanical properties of the products.
The development of new heat resistant varieties) increases the surface area of aluminum hydroxide particles, that is, micro refinement and ultrafine refinement, so that the partial pressure drop of water vapor on the surface of particles can improve the heat resistance performance of aluminum hydroxide, and also improve the mechanical properties and flame retardancy of materials. The experiment shows that when the average particle diameter of aluminum hydroxide is 5 u m, the oxygen index is 28 and the oxygen index reaches 33 when the particle size is <1 mu m.
The nominal size of micral1000 and micral1500 is 1 m and 1.5 m respectively, and the particle size distribution range is narrow, which improves injection molding and extrusion process. The hydrax series of aluminum hydroxide has 5 varieties with very narrow size distribution. The particle size of s-13 ultrafine aluminum hydroxide is 0.2 ~ 0.5 mu m.
In addition to the excellent flame retardancy of the base material, silicon - based flame retardant can also improve the processing performance, mechanical properties and heat resistance of the base material. Moreover, the ecological friendly, flame retardant materials have good recycling effect and can meet the strict requirements of the fire retardant. However, its processing technology is more complex, and the large-scale application is still a long time.
If the paint needs better weatherability, then MP will be more suitable than APP. Using MP as flame retardant fireproof coating is usually used for primer exposed steel, and the use of a coating; in the application of submarine facilities, MP shows more superiority. In order to obtain high performance coatings, general use epoxy fire retardant coatings were repeatedly coated in the surface, and then coated with two-component polyurethane paint. It has been found that the mixture of APP and MP also shows a certain synergistic flame retardant effect in the expansive epoxy fire retardant coating with high content of ATH as filling agent.
In December 2000, the industry standard for industrial powdery magnesium hydroxide (HG/T3607-2000) was established and implemented in December 1st of the same year. The production scale of magnesium hydroxide of different specifications and varieties abroad is large, and its application in different fields has been over 20 years ago. However, no official standards have been promulgated. Therefore, the proposal of China's industry standards is very pioneering.
