Inorganic flame retardant additive
Red phosphorus is an inorganic flame retardant additive and is one of the most widely used and most studied flame retardant of inorganic flame retardant additives.
Wu, studied the mechanism of flame retardant, think red phosphorus can make the most of polymer at relatively low concentration has good flame retardant performance, process stability, and has no effect on the physical performance of the matrix. It can produce free radical flame retardant in the gas phase, and it can form foam flame retardant in coagulation. However, it is easy to produce the highly toxic gas phosphating (PH3), the dust is easy to explode, and it is not easy to disperse in the polymer, which limits the application of this flame retardant additive. For this reason, the red phosphorus was modified by physical or chemical methods, such as "packaging" red phosphorus granules, namely microencapsulated red phosphorus, to make up for its defects.
Boron compound is a commonly used inorganic flame retardant additive, which is mainly used in zinc borate. The flame retardant additive obviously improves the resistance of the products, has excellent flame retardant, smoke suppression, extinguishing the arc of the property, can make the article emit less toxic and harmful smoke when burning. The main mechanism of flame retardant is heat absorption and dilution and the formation of insulation layer. Zinc borate can lose crystal water, when higher than 300 ℃ to heat absorption cooling effect.
About 38 percent of zinc borate zinc is in the gas phase with zinc oxide or zinc oxide, and the flammable gas is diluted to reduce its combustion rate, further increasing its flame retardancy. Generally zinc borate flame retardant additive and halogen compound. During the burning process, the flammable surface will cover some of the non-volatile zinc and boric acid to isolate the air. This coating can inhibit the occurrence of flammable gases and also prevent oxidation and heat. In addition, the presence of boric acid can induce the formation of a large amount of carbon, and the increase of carbon can also reduce the escape of combustible materials and have a good effect on the smoke suppression.
Antimony trioxide, colloid antimony and antimony pentoxide sodium is the main products of antimony series flame retardant additive, among which the meglumine antimoniate trioxide is widely used, mainly used in plastics and fabric flame retardant, flame retardant additives can be used for rubber, wood.
Its flame retardant mechanism is generally believed: (1) antimony oxide is covered by liquid or solid surface of the burners, and ACTS as an insulating air; (2) the combustion temperature is reduced due to the melting and evaporation of antimony. (3) into the antimony oxide after steaming, the flame formed in various antimonide and halogen free radicals, the product of the decomposition can dissipate the energy of flame, change combustion chemistry, which have the effect of inhibition.
Triisobutyl Phosphate (TIBP)
Cas No:126-71-6
HS Code HS: 29199000
The most important indicator of product: colorless transparent liquid Content ≥ 99%, moisture ≤ 0.2, Acid value ≤ 0.1, Chroma ≤ 20
Raw materials:phosphorus oxychloride and isobutanol as the main raw material.
Belong to several categories of dangerous goods:
Currently Triisobutyl Phosphate(TIBP) general cargo exports are not dangerous.
Packing: NW 200KG / galvanized iron (a small cabinet loaded 16 tons a child care), 1000KG/IB barrels (a small cabinet loaded 18 tons), or 23 tons ISOTANK.
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.
Polymer in burning many high-energy free radicals, the expansion type flame retardant additives can capture free radicals in the process of decomposition of the material (e.g., PO), so as to cut off free radical chain reaction to achieve the purpose of flame retardant.
As the application of high polymer materials is becoming more and more widespread, and the environmental protection is becoming more and more popular, the flame retardant performance of materials is also higher and higher. In order to better satisfy the requirement of the composite flame retardant, improve the effect of flame retardant additives used and field, in the future should focus on the following aspects: aiming at some traditional flame retardant additives, because there were some defects, the flame retardant performance should be engaged in this kind of flame retardant additives "defect". Such as inorganic flame retardant additives surface modification, nano-chemical technology and so on.
The synergistic flame retardant mechanism of flame retardant additive is explored. A single flame retardant additive may not have good flame retardant effects, but if combined with other flame retardant additives, it may be more desirable.
Research environmental protection type flame retardant additive. With the continuous development of modern science and technology and the growth of awareness of environmental protection, green flame retardant additives will more and more be taken seriously, to develop environmentally friendly flame retardant additive will be the focus of future research directions.
The development of a new compound flame retardant additive, which can be used to flame retardant materials from condensed phase, gas phase and liquid phase, is also an important direction for future development of flame retardant additives.
Magnesium hydroxide has been dehydrated at a higher temperature range, so it can be used in flame retardant pyrolysis polymers and has a wider range of applications.
