Phosphorus based flame retardants for Polyurethane
Worldwide except inorganic flame retardant, still with brominated flame retardants, but the combustion of brominated flame retardants to form polybrominated benzoxadiazol Ying (PBDD) and two polybrominated dibenzofuran (PBDF), will cause damage to human organs, and will produce a lot of smoke induced suffocation, so the development of halogen flame retardants is restricted.
Flame retardant solution type flame retardant combustion smoke, corrosive gases and inorganic flame retardant high amount of material physical and mechanical properties of defects such as halogen, high flame retardant, low smoke and low halogen non-toxic, etc., phosphorus flame retardant market has great potential, the research and development of flame retardant more efficient is the future direction of development.
Because of the double functions of flame retardant and plasticizing, the raw material resource is rich and the cost is low, polyurethane phosphorus flame retardant has a good market prospect.
5 types of flame retardant mainly include halogen containing phosphate, phosphate, compound phosphate, polyphosphate and phosphorus and its derivatives.
Of course, the flame retardant has some room for improvement, organic phosphorus products for oil, in the process is not easy to be added to the polymer, which is applied in the polyurethane foam, soft PVC, transformer oil, cellulose resin, natural and synthetic rubber. In addition, most phosphate flame retardants are easy to hydrolyze and biodegradable. No environmental durability and bioaccumulation problems are encountered in use.
At present, the market of phosphorus based flame retardants is mainly polyurethane, engineering plastics, copper clad laminate and fire retardant coatings. Among them, the phosphorus substitution in the field of polyurethane is basically completed. In the field of engineering plastics alloy, such as PC/ABS, mPPO, PBT/PET, PA and so on, the substitution of phosphorus flame retardants is also accelerating, and the application of halogen-free phosphate flame retardants in PC/ABS and mPPO has completely replaced the brominated flame retardants.
Phosphorus based flame retardant for polyurethane refers to inorganic or organic flame retardant containing phosphorus, which can be divided into inorganic phosphorus flame retardant and organic phosphorus flame retardant according to its properties.
Ammonium polyphosphate (APP) belongs to the inorganic flame retardant, is an important kind of halogen-free flame retardant, the molecules containing both nitrogen and phosphorus of 2 kinds of elements, in the process of phosphorus and nitrogen in flame retardant synergistic flame retardant effect and flame retardant effect is better than single flame retardant or single nitrogen containing flame retardant. Ammonium polyphosphate has the characteristics of large phosphorus content, high nitrogen content, good thermal stability, low moisture absorption, good dispersion, low toxicity, smoke suppression and so on. It can be mixed with other flame retardants, at the same time, it is cheap and safe to use. It has been widely used in many fields.
Tris(2-chloroethyl)phosphate(TCEP)Use:
1. Tris (2-Chloroethyl) Phosphate Has Excellent Flame Retardancy, Excellent Resistance To Low Temperature And UV Resistance, The Steam Can Only Be Used At 225 ℃ Above The Direct Ignition Can Be Fired, But The Fire The Source Is Immediately Self-Extinguishing. This Product Is A Flame Retardant Not Only Can Improve The Material Level Of Flame Retardant Materials, But Also Improve The Flame Resistance Of Water Resistance, Acid Resistance, Cold Resistance And Antistatic Properties. Commonly Used In Flame Retardant Nitrocellulose And Acetate Fiber As The Substrate Of Paint Coatings, Unsaturated Polyester, Polyurethane, Acrylic, Phenolic Resin, Can Also Be Used For Soft PVC Plastic Flame Retardant. This Product Is Used For The Amount Of Unsaturated Polyester 10% To 20%, In The Polyurethane Rigid Foam (Flame Retardant Polyether As Raw Material) Can Be About 10% In The Soft PVC Used As Auxiliary Plastic Flame Retardant When The 5% To 10%. Flame Retardants, Uranium, Thorium, Plutonium, Technetium And Other Rare Metal Separation Solvent Or Extractant.
2. This Product Is Widely Used In Chemical Fiber Fabrics, Cellulose Acetate As A Flame Retardant, In Addition To Self-Extinguishing, But Also Improve Water Resistance, Cold Resistance And Antistatic Properties. The General Amount Of 5 To 10 Copies. This Product Is An Excellent Flame Retardant For Synthetic Materials, And Has A Good Role In The Promotion, Widely Used In Cellulose Acetate, Nitrocellulose Varnish, Ethyl Cellulose, Polyvinyl Chloride, Polyvinyl Acetate, Polyurethane, Phenolic Resin , In Addition To Self-Extinguishing Products, But Also Improve The Physical Properties Of Products, Products Feel Soft, Also Known As Oil Additives And Rare Elements Of The Extractant, And Flame Retardant Rubber Conveyor Belt Is The Main Flame Retardant Materials , The General Amount Of Added 5% To 10%.
3. Used As Additive Type Halogenated Phosphate Flame Retardant And Plasticizer. Molecules In Both Phosphorus And Chlorine, Flame Retardant Effect Is Remarkable, Not Volatile And Hydrolysis, Good Stability To Ultraviolet Light. Applicable To Phenolic Resin, Polyvinyl Chloride, Polyvinyl Acetate, Polyurethane And So On. Also Used As Nitrocellulose Coating Flame Retardant, PVC Flame Retardant Plasticizer, Metal Extractant, Gasoline Additives And Polyimide Processing Aids And So On. Can Improve Water Resistance, Weatherability, Cold Resistance, Antistatic Property. Reference Dosage 5% To 20%.
As an additive of composite materials, flame retardant must have certain properties. From the general trend of development in the world, the performance requirements of flame retardant products are more and more strict in the world. At present, the main development trend of flame retardants is as follows: 1. Non halogenated; 2, ultra-fine flame retardant; 3, surface treatment of flame retardant; 4, study the synergistic effect of flame retardant system; 5, smoke inhibitor development prospect is broad. In view of this, continuous development of efficient, environmentally friendly, non-toxic composite flame retardant new varieties is the main direction of the future development of flame retardant industry.
With the electrical, household appliances, chemical, oil, rubber, plastics, automotive, shipbuilding, synthetic fiber, paint, paint, paper and other industries and the development of fire, increasingly stringent environmental regulations, brominated flame retardants prices in Western Europe and North America market halogen especially brominated flame retardant consumption growth slow, inorganic products of ammonium polyphosphate such as non-toxic and popular.
In addition, the demand for phosphorus based flame retardants is increasing year by year at home and abroad. At present, the annual demand for various types of flame retardants is about 700 thousand tons. The proportion of phosphorus flame retardants increased from 20% in 2007 to 28% in 2012, with a growth rate of 15%, much higher than the overall growth rate of flame retardants.
Ammonium polyphosphate (APP) is a kind of important inorganic additive type halogen-free flame retardant, the phosphorus, nitrogen content, good thermal stability, are nearly neutral and can mix with other flame retardants, and low price, low toxicity, safe use, widely used in various fields.
But due to the chemical structure of ammonium polyphosphate itself, strong hygroscopicity, under high temperature and high humidity conditions will be ion segregation, reduce the flame retardant efficiency, and joined in the organic material of ammonium polyphosphate will cause the mechanical strength of the material itself is reduced, affecting its normal use.
