Flame retardant dose
Flame retardant is a kind of auxiliary agent which can improve combustible polymer, prevent the material from being ignited and prevent flame spreading. The research and development of fire retardant coating is closely related to the development of flame retardant. The selection of flame retardant and flame retardant system plays a key role in the performance of fire retardant coating.
In 1990, the amount of flame retardant in the world was about 500,000 t, 85% of which were additive flame retardant and 15% were reactive flame retardants. And aluminum hydroxide is about 50% of the total dose. In the United States, the annual growth rate of aluminum hydroxide flame retardants is higher than 30% in recent years. The alumina white quality of aluminum hydroxide produced by shandong aluminum plant in China has a large share in domestic and foreign markets.
Magnesium hydroxide, by contrast, the development of late, it besides has the advantages of aluminum hydroxide, but also has the feature of high decomposition temperature (the initial decomposition temperature of value = "320" UnitName = "℃ > 320 ℃). In foreign countries, magnesium hydroxide has been used in polypropylene, polyethylene and unsaturated polyester coatings.
Our country carries out this kind of research mainly has hangzhou chemical research institute and other units. Sea salt byproduct of magnesium chloride and liaodong region of the newly discovered water magnesite, etc., are the magnesium hydroxide provides a rich source of raw material, at the same time, the surface treatment technology in China is also gradually strengthened, which will greatly promote the development of flame retardants.
Sb2O3 is one of the first inorganic flame retardants to be used, which is second only to aluminum hydroxide. Sb2O3 abroad accounts for about a half of the total consumption of Sb2O3. The production of antimony in China is the largest in the world. The amount of flame retardant is about 8000~8500t per year, of which Sb2O3 is 2500~ 3000t, while Sb2O3 for flame retardant is 300t.
Phosphorus and phosphor compounds are the most important types of flame retardants, and the demand for halogen-free systems and phosphor flame retardants is increasing rapidly. Phosphorus-containing flame retardant with bromide were modified, and can improve the flame retardant efficiency, reduce the usage, and new type of phosphorous flame retardants can make ordinary phosphate plasticizing effect caused by the mechanical strength to minimize loss.
For example, two kinds of polyphosphate (APP), one of them, Exolit422, has higher molecular weight, good thermal stability and low solubility, with a whiteness coefficient of 90~ 95.
Triisobutyl Phosphate (TIBP)
The following detailed description below about Triisobutyl Phosphate raw materials:
Raw materials of this product with three phosphorus oxychloride and isobutyl alcohol as main raw materials, respectively by esterification, dealcoholization drive acid, neutralization and water washing, distillation method to get the Triisobutyl Phosphate products.
The above is the raw material of this product specifications, such as Triisobutyl Phosphate raw materials to further understand please contact us.
Triisobutyl Phosphate(TIBP) is mainly used for antifoamer and penetrant. It is also be widely used in printing and dying, ink, construction, and oil field additives, etc. Another chemical name of Triisobutyl Phosphate (TIBP) is tri -butyl phosphate.
Another product Exolit462 chemistry the same as the Exolit422, but its surface cladding processing, thus inhibiting the it react with other additives, and improve the wave resistance, especially suitable for outdoor use.
Boron flame retardants mainly include hydrated zinc borate (ZB) and barium metaborate, etc., they are non-toxic, low water solubility, heat stability, particle size, good dispersion characteristics, especially the ZB, as a kind of multifunctional additives, flame retardant, into charcoal, smoke suppression and other performance, USES a very wide range.
MoO3 and sodium molybdate can be used together with Al(OH)3 and Sb2O3 to produce synergistic flame retardant and anti-smoking effect. Other corrosion system is mainly used for flame retardant, smoke suppression, inorganic substances, such as aluminium trihydrate (ATH) and magnesium chloride and boride, its development trend is to narrow particle size distribution, and small or submicron particle size tends to be
In order to improve its mixed rheology, it is developing 0·25 mu m super fine varieties. Ultra fine zinc borate (ZB)Flamtardz series products, whose particle size is less than 1 mu m, can be used as a good flame retardant.
By improving the purity of natural magnesium hydroxide, the cost can compete with the grinding ATH, and now the average particle size is less than 3 mu m. In addition, the coating technology has been developed to improve the wettability and impact resistance of flame retardant additives.
The research and production of flame retardants in our country started late, but it has developed rapidly and has formed the flame retardant system from scientific research to production, from inorganic to organic, from single to complex. Units engaged in research on flame retardants have a chemical research institute of Beijing, tianjin institute of synthetic materials, Shanghai chemical industry research institute, zhejiang province chemical industry research institute, Beijing institute of technology, sichuan fire and so on more than 20, mainly for bromine, chlorine, phosphorus, nitrogen, and the research of inorganic flame retardants. There are more than 50 kinds of production plants. There are over 100 varieties and about 20~30 special flame retardant varieties.
