Halogen free flame retardant for ABS alloy
In recent years, due to the six ring of decabromodiphenyl oxide and twelve alkyl bromide was included in the effects of persistent organic pollutants, the development of halogen flame retardant were greatly affected, and the resulting concept of no halogen flame retardant. Corresponding to halogen flame retardants, this concept has promoted the development of research and manufacture of halogen free flame retardants for many ABS alloys, including phosphorus based flame retardants. The demand for halogen-free flame retardants for ABS alloys is increasing.
And after 2005, bromine prices continue to rise, in stark contrast with the domestic price stability of phosphorus resources, the price gap between the two increased rapidly, even the brominated flame retardant price once more than doubled the price of most of the phosphorus flame retardant. Therefore, the rising price of brominated flame retardants promoted the rapid growth of phosphorus or phosphorus nitrogen based flame retardants in the -2012 market during 2005.
In 2012, China's consumption of flame retardant was about 474 thousand tons, of which the proportion of phosphorus based flame retardant was the largest, the total amount was about 179 thousand tons, and the consumption of 90 thousand tons in 2008 was 16.4%. There are many reasons for the rapid growth of phosphorus flame retardant market. We believe that the most important reason is the high price of brominated flame retardants, followed by the downstream market, and the third is the impact of policies and regulations.
First, the rising price of brominated flame retardants has led to the rapid growth of phosphorus containing flame retardants. Due to the rising price of brominated flame retardants, it is necessary to stimulate the consumption of phosphorus containing flame retardants, and promote the growth of phosphorus flame retardant consumption market.
The rapid development of the industry led to the research and manufacture of halogen free flame retardants for ABS alloy. Halogenated Phosphate Chinese flame retardant and halogen-free phosphate consumption proportion of flame retardant consumption of 74%, mainly used for building insulation materials, fireproof coatings, adhesives and CCL, the rapid development of the field of composite materials, which is widely used in halogen free phosphate PC/ABS alloy; ammonium polyphosphate is mainly used for fire retardant coatings and general plastics time; phosphate is mainly used for polyamide, polyester and other engineering plastics engineering plastics; red phosphorus flame retardant is mainly used in engineering plastics and general plastic flame retardant; phosphaphenanthrene flame retardant agent is mainly used for copper clad laminate.
Since 1980s, China began to study the synthesis and application of ammonium polyphosphate, especially in recent years. In 2003, the amount of domestic ammonium polyphosphate reached 8 thousand tons, and reached 26 thousand tons in 2012, showing a sustained growth trend. With the strengthening of the research and manufacturing requirements of halogen-free flame retardants, phosphorus based flame retardants will continue to play a steady role in their future price advantage.
Triphenyl Phosphate (TPP)
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.
The degree of polymerization of ammonium polyphosphate according to their size, can be divided into low and high poly, in three, the polymerization degree is higher, the water solubility is smaller, and vice versa; according to the structure can be divided into crystalline and amorphous, crystalline ammonium polyphosphate as water insoluble long-chain polyphosphate.
The general formula of APP is (NH4) n+2PnO3n+1, the appearance is white powder, in which polymerization degree n is water-soluble between 10-20, called short chain APP; n is greater than 20 is water-soluble long chain APP, N is the main factor affecting the performance of APP. As an inorganic phosphorus flame retardant developed rapidly in recent years, especially polyphosphate with high polymerization degree, it has been widely used in many fields, such as materials, coatings, etc..
Ammonium polyphosphate based materials as expansion type flame retardant is widely used in the field of flame retardant, flame retardant in the development with the global non halogenated direction, using ammonium polyphosphate as the main raw material of intumescent flame retardant industry become hot, especially a greater demand for high degree of polymerization of ammonium polyphosphate.
Although the modified method can strengthen the combination between ammonium polyphosphate and organic substrates, reduce the influence on the mechanical properties of the substrate, but no matter what method can only be applied to a part of the flame retardant material, not universally applicable, so the surface modification only for one or a class of substances. Increasing the polymerization degree of ammonium polyphosphate can fundamentally solve the problem of moisture absorption of ammonium polyphosphate, so the production of ammonium polyphosphate with high polymerization degree is the current direction of development.
In view of this, we should increase the research and development of ammonium polyphosphate synthesis technology in the future, at the same time pay attention to the waste gas and wastewater treatment in the production process, expand production scale, and enhance market competitiveness. In addition, the ammonium polyphosphate was modified by various techniques to enhance the thermal stability, and resin compatibility and reduce hygroscopicity, for substrate and different applications, developing a series of specialized products, poly ammonium phosphate, in order to meet the needs of different consumers.
At present, the global flame retardant products are in the stage of structural adjustment, but also for the development and production of ammonium phosphate, ammonium polyphosphate, fluorine based ammonium phosphate, boron phosphate, red phosphorus flame retardant products provide a broad market.
