Flame retardant for combustible materials
As people to the attention of the combustible material flame retardant, flame retardant has been with the widely application of the polymer material and got great development, and the people environmental protection consciousness enhancement, new varieties of flame retardant appear constantly, some emerging technology is constantly applied to the research and production of flame retardant.
The research on flame retardants has entered a relatively perfect stage of development, and environmental protection, complex and expansive flame retardants are very popular. Flame retardant at home, combustible material is a new industry, the relevant research started late, has made great development, but compared with advanced countries, on the yield and variety structure is a certain gap. At present, domestic research and development focuses on inorganic flame retardants, red phosphorus microencapsulation, expansive flame retardant and other fields, and has achieved certain results. In the future, the development trend of combustible materials flame retardant will be a new flame retardant system with no toxicity, halogen, low smoke and minimum environmental impact. It can be predicted that there will be a booming future for flame retardants worldwide.
Mechanism of chain reaction termination. The decomposition products of flame retardants are easy to function with active free radicals, and the concentration of some free radicals is reduced, so that the chain lock reaction as a combustion pillar cannot be carried out smoothly. When the polymer burns, it is generally decomposed into hydrocarbon, and the hydrocarbon is further oxidized at high temperature to decompose OH free radicals, and the chain reaction of OH is causing the flame to burn continuously.
Synergy. In polymer flame retardant system, to improve the efficiency of flame retardant, flame retardant often use a kind of matrix with another agent material with known writers association effect, this is composed of two or more components of flame retardant system known as the association effect of flame retardant system. The coactive agent itself does not necessarily have the flame retardant effect, but it can show certain flame retardancy when used with flame retardant, which is its own characteristic.
The flame-retardant effect of the coactive system is often greater than that of the flame retardation caused by the single component in the component, so it is also called the synergistic effect (SE). The coactive flame retardant system mainly includes the coeffect of halogen-antimony, the co-effect of bromine-ammonia, the co-effect of bromine chloride, the co-effect of phosphorus-nitrogen, the co-effect of phosphorus-phosphate, the co-effect of halogen-boron, antimony - phosphorus, etc.
Isopropylphenyl Phosphate(IPPP50)
Cas Number: 68937-41-7
Customs Code HS: 29199000
Tax Rebate: Current Isopropylphenyl Phosphate, Flame Retardant IPPP50 Tax Rebate Of 9%.
Net Weight 200KG / Galvanized Iron Drum (A Small Cabinet To Play With 16 Tons), 1000KG / IB Barrel (A Small Cabinet 18 Tons) Or 23 Tons ISOTANK.
Isopropylphenyl Phosphate(IPPP50)Use:
Isopropylphenyl Phosphate, Flame Retardant IPPP50 This Product Is Compatible With Vinyl Chloride, Nitrocellulose, Synthetic Resin And Natural Resin, Etc. Because Of The Above Advantages, Reofos Series In Industrial Production Is Widely Used: PVC Film As Flame Retardant Plasticizer, Reofos Increase In The Amount Of Oxygen Index Increased, Enhanced Flame Retardant. In The Rubber Industry Can Be Used As Chloroprene Rubber And Rubber Flame Retardant Plasticizer; In Other Industries Can Be Used As Lubricants With Extreme Pressure Additives And Digestion Of Cellulose Paint, Resin, Phenol Resin And Other Flame Retardants.
Isopropylphenyl Phosphate, Flame Retardant IPPP50 Use Is Also Applicable To Fabric Coating, Circuit Boards, Flooring, Textiles, PVC, Phenolic Resin And Other Fields.
Phosphorus-containing flame retardants is a large family of flame retardant, it is widely used in all kinds of flame retardant materials, including plastic, rubber, paper, wood, paint and textile, etc., have very important position in the field of flame retardant and its consumption is second only to halogen flame retardants.
Organic phosphorus flame retardants have good flame retardant effect, good compatibility with polymer, so most widely used in polyurethane, engineering plastics, the effect of plasticizer, lubricant concurrently at the same time.
Chlorine flame retardant plasticizer is still a large amount of flame retardant due to its low price. Chlorine content is higher of chlorinated paraffin industry is important for flame retardant, due to the poor thermal stability, applies only to composite materials processing temperature below 200 ℃, the chlorine content of different 42, 50, 70 points, mainly on flame retardant of high chlorine content. The heat stability of chlorinated and tetrachloro-phthalic anhydride is high and the flame retardant of unsaturated resin is commonly used.
As the main substitute of bromine generation of flame retardants, organic phosphate to get a number of applications throughout the world, and has been widely distributed in various environmental media, so you need to examine organophosphate exposure effect to human body and its potential health effects. Although about biological sources of organic phosphate in the body, there is no clear conclusion, but is generally believed that in addition to food intake and inhaled aerosol containing organic phosphate, organophosphate can also enter the body of adsorption, absorption by skin.
Schindler etc. (2009) established a SPE - GC - MS was developed for the determination of trace organic phosphate and its metabolites in human urine method, and for the first time in the German detection of organophosphate metabolites in urine samples, and proved that the human body metabolism ability of organophosphate. Although have established various kinds of methods for determination of organophosphate in human blood, and reported in human blood samples detected organophosphate, but due to the stored blood organophosphate plastic containers may cause pollution, source of organic phosphate in the blood is still unable to confirm. Therefore, there is still no literature to confirm the presence of organophosphate in human blood.
