Environment-friendly flame retardant for polyolefin materials
At home and abroad developed many kinds including environmental friendly flame retardant polyolefin materials, many of them also to the corresponding materials have relatively high flame retardant efficiency, and environmentally friendly flame retardant polyolefin material can produce good mechanical properties and appearance have good flame retardant materials, but perhaps because of the price and technology, at present and the promotion Chinese is not very good.
As a environment-friendly flame retardant for polyolefin materials with good performance, it is generally believed that:
With high flame retardancy efficiency, it can easily make the flame retardant material reach its due flame retardancy grade.
The physical properties of the materials made after use should not be changed too much.
It has good compatibility with the material and can be dispersed evenly in the flame retardant material and has good affinity.
The processing technology is feasible, and the traditional technology can be used.
It can be accepted by the market, which can bear the price and have high cost performance.
Environmental protection, non-toxic, no harmful substances release;
Inorganic flame retardant products are more mature, such as: three oxidation two antimony, magnesium hydroxide, some of the price is relatively low, like magnesium hydroxide, aluminum hydroxide not only cheap and does not produce a lot of smoke burning flame retardant materials, mainly for the release of carbon dioxide and water will not cause great harm to the environment of the material, so it belongs to the green environmental protection product, however, this kind of flame retardant is the fatal disadvantage of flame retardant efficiency is low, need high added amount can make the material of flame retardant, and organic inorganic flame retardant thermoplastic resin compatibility is poor, not easily dispersed in the resin, even dispersion, affinity is not good, so the manufacturing materials tend to have mechanical properties let a person to accept, or greatly reduce the impact properties of materials, or materials of all sorts of reasons by loss of flexibility, Because of the limitations of its application, it is often used in situations where the mechanical properties of the materials are not high.
Of course, inorganic oxidation retardants, such as three oxidation, two antimony and zinc borate, are often used as flame retardants, but their flame-retardant effects are mainly reflected in their flame-retardant effects, such as halogenated and other flame retardants. Their own flame-retardant effects are very low, or almost nothing.

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.
Aluminum hydroxide (ATH), namely alumina trihydrate the amount accounted for more than 4o% of the total use of flame retardant. ATH itself has three functions of flame retardant, smoke elimination and filling. Because it is non-volatile, non-toxic, and can produce synergistic flame retardancy with many substances, it is known as a nuisance free inorganic flame retardant. But ATH has the disadvantage of adding large amount, and it usually needs to add more than 5O% to show the most good flame retardancy. In order to overcome this shortcoming, we can use improved granulating technology to expand to the direction of superfining and narrow the particle size distribution, improve the coating technology to improve its dispersion in polymer, and use macromolecular bonding to deal with these problems.
The organophosphorus flame retardant DMMP is a colorless transparent liquid. The relative density (25 C) 1.160 + 0.005, viscosity (25 C) 1.75mPa? S, the freezing point of <-50 Deg. C, the boiling point of L80 Deg. C, flash point (opening) of more than 90 DEG C, pH = 1.0mgKOH / g, the phosphorus content 25%, moisture content is less than 0.05%, the decomposition temperature of >180 DEG C. It can be mixed with water and a variety of organic solvents. Low toxicity. It is used as an addition type flame retardant, which is suitable for unsaturated polyester, epoxy resin, phenolic resin, furan resin, polyurethane and so on.
Ammonium polyphosphate (APP) is a hot field in the development of flame retardants at home and abroad because it meets the development trend of halogen-free environment-friendly flame retardants.
APP in five different crystalline forms (I - V), on the crystallization of II type high degree of polymerization of ammonium polyphosphate most valued. Its polymerization degree and decomposition temperature are significantly improved, and its thermal stability and water solubility are low. It is an environmentally friendly and highly efficient inorganic flame retardant. It can replace halogen containing flame retardants, and is widely used in polyester, polyolefin plastics, rubber, high-grade intumescent fire retardant coatings and other fields. The foreign crystalline II type APP has been commercialized and has been applied in the field of polyester, polyolefin, polyurethane and other fields. The development of this product is still in its initial stage in China. At present, the Zhejiang Institute of chemical industry has done a good job in China. Its preparation methods and testing methods have applied for national invention patents.
Low hydrate zinc borate has many functions, such as high temperature resistance, flame retardancy, sterilization, antirust, smoke suppression, and so on. It is nontoxic and inexpensive. Boron deposits of the basic raw materials are rich in resources in China, with more than 40000kt (B2O3). Recently, Tibet has found tens of millions of tons of boron and magnesium ores, with a high grade of 30% and a magnesium content of more than 15%.
The annual production of China's plastics is above 8000kt, and it needs more than 150kt/a of flame retardant, but the domestic production is less than ten thousand tons at present. Therefore, the production and application of this product should be vigorously developed in order to meet the needs of the domestic and foreign markets.
