Research and manufacture of halogen free flame retardants
In recent years, due to ten pbdes and hexabromocyclododecane are on persistent organic pollutants (pops), the influence of the development of the phosphorus-containing flame retardants was great impact, and the concept of no halogen flame retardants. Corresponding to halogen flame retardants, this concept has led to the development of many halogen-free flame retardants including phosphor flame retardants.
And after 2005, bromide prices continued to rise, with the domestic price stability to form bright contrast, phosphorus resources makes the price gap between them increased rapidly, even higher than that of the price of bromine series flame retardant were once most of the phosphorus flame retardant prices more than doubling. As a result, the rise in the price of flame retardants for bromine is driving the rapid growth of the phosphor or phosphorus-nitrogen flame retardants in the market between 2005 and 2012.
In 2012, the consumption of flame retardant in China was about 47.40 million tons, including the largest proportion of phosphorus flame retardants, which totaled about 179,000 tons, and the annual consumption of 90,000 tons in 2008 was about 16.4%. Phosphorus flame retardant market keep the cause of the high speed growth is more, we think the most important reason is that its main rival bromine flame retardants caused by high prices, the second is the downstream market, the third is the impact of policies and regulations.
First, the price of flame retardant of bromine is increasing rapidly. Because of the rising price of the flame retardant of bromine, the consumption of phosphorous flame retardant is necessary to promote the growth of the consumer market of phosphorous flame retardant.
Secondly, the rapid development of the downstream industry led to the research and manufacture of halogen free flame retardants. Halogenated phosphate in China phosphorus flame retardant and halogen free phosphate consumption proportion accounted for 74% of phosphorus flame retardant agent consumption, mainly used for building insulation materials, fire protection coatings, adhesives and copper-clad r.p. panel and by the rapid development of composite material field, including halogen free phosphate in PC/ABS alloy; Ammonium polyphosphate is mainly used for fire retardant coatings and general plastics. The phosphates are mainly used in engineering plastics such as polyamide and polyester. Red phosphorus flame retardant is mainly used in engineering plastics and general plastic flame retardant; Phosphorus hybrid flame retardant is mainly used to cover copper plate.
Since the 1980 s, China started to study the synthesis and application of ammonium polyphosphate, particularly rapid development in recent years, domestic ammonium polyphosphate consumption reached 08000 tons in 2003, and in 2012 reached 26000 tons, a sustained growth trend. With the strengthening of research and manufacturing requirements of halogen flame retardants, phosphorus flame retardants will continue to play a steady development role in the future development.
Trixylyl Phosphate(TXP) Use
Phosphate Trisphenylene Phosphate Is Low, Resistant To Hydrolysis, Good Flame Retardant Can Be Used As Vinyl Resin, Cellulose Resin, Natural And Synthetic Rubber Plasticizer, Low Volatility, Good Water Resistance, Flame Retardant. Trichenylene Phosphate Use For Use In Combustible Turbine Oils, With Good Flame Resistance And Good Thermal Oxidation Safety, Good Lubricity, Extreme Pressure Antiwear Additives For Lubricants, Thickeners. Also Used For Fire-Resistant Turbine Oil, With Good Thermal Oxidation Stability, Lubricity, As A Lubricant Anti-Wear Additives, Plasticizers, But Also For Flame Retardant, Wear-Resistant, Resistant To The Mold Of The Cable, Ethylene Conveyor Belt, Artificial Leather, Foam, Flooring Materials, But Also In Metallurgy, Electricity, Mechanical Engineering And Other Aspects As A Fire-Resistant Hydraulic Oil.
The polymerization degree of polyphosphate is divided into three kinds: low poly, medium and high poly, the higher the polymerization degree, the smaller the water solubility, and vice versa. The structure can be divided into crystallized and amorphous, and the crystalline polyphosphate is a long chain water-insoluble polyphosphate. The general formula of the APP is (NH4)n+2PnO3n+ 1, and the appearance is white powder, where the polymerization degree n is water-soluble between 10-20, which is called short chain APP.
N is more than 20 for water insoluble long chain APP, and n is the main factor affecting the performance of the APP. As a rapid development in recent years, phosphorus is an inorganic flame retardant, especially high polymer polyphosphate, which has been widely used in many fields such as materials and coatings. Ammonium polyphosphate as the basis of expansion type flame retardant materials are widely used in flame retardant field, with no halogenated flame retardants is developing around the world, with ammonium polyphosphate as the main raw material expansion type flame retardant is becoming a hot spot of the industry, especially the demand of high polymerization degree of ammonium polyphosphate Ⅱ - type.
Although the modified method can strengthen the combination of ammonium polyphosphate and between organic substrate, reduce the impact on base material mechanical properties, but no matter what method can only apply to the part of the flame retardant base material, not universal, so the surface modification can only be on one or a class of substances. The polymerization degree of ammonium polyphosphate can be used to solve the problem of the absorption of ammonium polyphosphate. Therefore, ammonium polyphosphate, which produces high polymerization degree, is the current development direction.
In view of this, the research and development of high polymerization polyphosphate synthesis technology should be increased in the future. Meanwhile, the waste water treatment in the process of production should be valued, and the scale of production should be expanded to enhance market competitiveness. In addition, used in a variety of technology for modification of ammonium polyphosphate, to enhance its heat stability, compatibility with the resin and reduce its hygroscopicity etc, in view of the base material and different application fields, development of seriation, specialty of ammonium polyphosphate products, to meet the needs of different consumers.
At present, the global flame retardant product is in the stage of structural adjustment, and it also provides a broad market for the development of the production of ammonium phosphate, ammonium polyphosphate, ammonium fluorine phosphate, boron phosphate, red phosphorus and other flame retardant products.
