Polyurethane plastics foam flame retardant
The application field of plastics is expanding, but it is flammable and high in heat, easy to ignite and bring unexpected danger and loss to mankind. Therefore, from the late 60s, people began to pay attention to and emphasize the natural and synthetic materials of the flammability, polyurethane plastic foam flame retardant began as an important class of auxiliaries, first in the chemical fiber and plastics industry rise.
Since 70s, the polyurethane plastics foam flame retardant began to develop rapidly, and the consumption and variety rose sharply, increasing at about 6% ~ 8% every year. Among the many additives in the plastic industry, the consumption of polyurethane plastic foam flame retardant has become a big variety second only to the plasticizer.
The flame retardants are usually divided into addition and reacting types. Most of the added flame retardants are used in thermoplastic plastics, which are the most productive flame retardants in the world at present, accounting for 90% of the total output of the flame retardants. Reactive flame retardants are mostly used in thermosetting plastics.
The flame retardant can be divided into inorganic flame retardant and organic flame retardant according to the chemical structure. Inorganic flame retardant mainly include antimony compound, inorganic boron compound, inorganic phosphorus system flame retardant, inorganic hydroxide and so on. Organic flame retardants include organic halogen flame retardants and organophosphorus flame retardants.
The development of flame retardant antimony products with high price, large amount of smoke, and three oxidation two antimony halogen flame retardant is essential for collaborative agent, so the three oxidation two antimony particle fineness requires more and more fine, not only can greatly reduce the consumption, improve flame retardancy, but also greatly reduce the amount of smoke. The fineness of the present is usually from a few microns to 0.01 M.
Superfine and high pure antimony oxide, with an average particle size of 0.02 M and a content of 99.999%. Nyacoladp480 is a five oxidation two antimony with particle size less than 0.1 M. Adding 1% can play a good role in flame retardancy in PP, and it will not affect the impact strength and transparency of PP.
In addition, the combination of three oxidation, two antimony and aluminum hydroxide, zinc borate and fluorborate can not only reduce the amount of three oxidized two antimony, but also reduce the amount of smoke. In a word, the development of antimony flame retardant is the hot spot of antimony flame retardants.
The development of brominated flame retardants is brominated flame retardants. Although the amount of cigarette smoke is large, they are still the main force of flame retardants in the future for a long time. With the progress of technology, the new development of bromine flame retardants in the world is to continue to increase the content of bromine and increase the molecular weight.

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.
For example, pb-68, the main component is brominated polystyrene, the molecular weight is 15000, and the bromine content is 68%. Poly (five bromophenol) acrylate with bromine content of 705% and molecular weight of 30000~80000. These flame retardants are especially suitable for all kinds of engineering plastics. They are much better than many small molecule flame retardants in migration, compatibility, thermal stability, flame retardancy and so on, which may become future upgrading products.
The development of phosphorus flame retardants is mostly liquid, which is mainly used in Pu, PVC and other plastics. The main disadvantages of the small molecular phosphorus flame retardant are large volatility and low heat resistance. At present, efforts are being made to develop macromolecular compounds and oligomers. Halogenated phosphate esters contain phosphorus, bromine and chlorine, which are of low viscosity and are especially suitable for casting products and Pu soft foam plastics.
The multi functionalization of flame retardancy, plasticization, flame retardancy and crosslinking is another major aspect of the development of phosphorous flame retardants. Flame-retardant plasticizers (especially at low temperature) are mainly used in PVC products, such as the two isopropyl benzene phosphate produced at home. Flame retardant crosslinking agent is a kind of phosphorus containing polyols with reactivity. It can be used not only as a reactive flame retardant for PU, but also with brominated flame retardants and epoxy resin, which can greatly reduce the consumption of bromine flame retardants.
Phosphorus flame retardants will also develop to low toxicity in the future, not only to solve the toxicity of the products themselves, but also to consider the toxicity of combustion decomposition products and the environmental pollution of waste products, and even consider the toxicity problem during the process of production, sale, storage and transportation.
The development of non halogenated inorganic flame retardant most organic flame retardant containing halogen, hair smoke in combustion, toxic gases, so non halogenated flame retardant materials in recent years, more and more urgent. Some plastic products in some developed countries have begun to prohibit the use of halogen flame retardants.
The German environmental group, pal, has banned bromide and antimony oxide in the shell of electronic equipment since 1995. Tc095 in Sweden stipulates that organic bromine and organic chlorides are prohibited in all electrical and electronic equipment that are more than 25g in plastic parts. Although halogen flame retardants are still dominant abroad at present, the tendency to gradually be replaced by non halogen flame retardants is clear in the future.
