2017-12-18 12:10:42
Phosphate plasticizer has good phase solubility with PVC and other resins, it is also transparent, but has toxicity. Phosphate plasticizers are both plasticizers and flame retardants.
Aromatic phosphate ester plasticizer has poor performance at low temperature, while aliphatic phosphate plasticizer has low temperature performance, but its thermal stability is poor, and its durability is not as good as aromatic phosphate. The main varieties are trimethylamine phosphate and three benzyl phosphate.
(1) Trimethyl phosphate (TCP)
(2) three benzyl phosphate (TPP). The white needle like crystals of the aromatic scent of the microstrip are slightly soluble in ethanol, ether, benzene, chloroform and acetone.
(3) phosphoric acid two - octyl (DPOP). Light yellow transparent oil like liquid.
(4) toluene phosphoric acid two benzyl ester (CDPP). A clear and odorless oily liquid.
Trimethyl phosphate, molecular formula: C21H21O4P, colorless or yellowish transparent oil like liquid. It dissolves in water and dissolves in most organic solvents, such as ethanol and benzene. By catalytic synthesis method or indirect method of phosphorus heteropoly acid salt (cold) preparation, is an important chemical raw materials in modern industry, mainly used for plastic plasticizer and paint plasticizer.
Trimethylamine phosphate industrial products are mixtures of three isomers, which should usually be removed to the most toxic adjacent isomers as much as possible. Trimethyl phosphate is a refractory material for thermal stability. It is difficult to hydrolyze in acid solution. 6- nitro -1- methyl phenol was formed by nitrification of the adjacent isomers in acetic acid with nitric acid. With potassium carbonate heating generation o-cresol, 4,5- two methyl xanthones and creosote with smelling liquid. The ortho isomers are heated together with potassium cyanide to obtain o - tolyl cyanide and free o - cresol. Para isomers are heated together with potassium cyanide to produce p-toluyl cyanide and p-cresol.
Trimethyl phosphate is a flame retardant plasticizer. It is compatible with many cellulose resins, vinyl resins, polystyrene and synthetic rubber, especially with PVC compatibility, and can be used as an assistant medium with poor compatibility, so as to improve compatibility with resins. This product has good compatibility, flame retardancy, mildew resistance, wear resistance, pollution resistance, weatherability, radiation resistance and electrical properties. This product is used for paint, which can increase the flexibility of the film. This product is used for synthetic rubber and viscose fiber as plasticizer.
Three benzyl phosphate (flame retardant TPP) is a compound containing phosphorus, which can be used as a halogen-free environment-friendly flame retardant to dissolve in organic solvents. A white crystalline powder, odorless, slight deliquescence; vapor pressure 220 DEG 0.01kPa/20 DEG C; flash point; melting point of 47-53 deg.c; boiling point of 370 DEG C; solubility: insoluble in water, slightly soluble in ethanol, soluble in benzene, chloroform, acetone, soluble in ether; relative density (water =1) relative to:1.21; steam density (air =1) 9.42; stability; risk label: flammable, toxic, harmful to the environment.
Three phosphoric acid phenyl ester is mainly used as flame retardant engineering plastics laminate and phenolic resin plasticizer; used as a synthetic rubber softener, manufacturing Trimethyl phosphate as a raw material; used for nitrocellulose and cellulose acetate, flame retardant plasticizer, fire resistance, solvent paint, synthetic resin, nitrocellulose paper sizing agent and roof the camphor substitute made of celluloid.

Use of two octyl terephthalate (plasticizer DOTP)
1.DOTP has good electrical and thermal properties. It can be used to replace DOP in the sheath of PVC plastic wire and can also be used in the production of artificial leather membrane. In addition, with excellent compatibility, terephthalic acid ester is two PVC acrylonitrile derivatives plastic plasticizer, plasticizer, plasticizer, polyvinyl butyral nitrile rubber plasticizer, plasticizer for cellulose nitrate. The improvement of the product and plays the role of hardness and deformation, can be used as softener in NBR, chloroprene rubber, EPDM rubber and other products three. Especially for cable material, it has good plasticizing effect and low volatility. It is widely used in various products that require heat resistance and high insulation. It is an ideal plasticizer for producing 70 PVC cable material and other volatile resistant products.
2.DOTP is used for the PVC products in the car, which can solve the fog problem of the glass window. DOTP is also used for high quality lubricants or lubricant additives furniture and interior decoration paint, and precision instruments, nitro varnish additives, paper softener, biaxially oriented polyester amide membrane film, plastic bags and other crafts, plasma storage.
3. because the linear molecular structure of DOTP is similar to DOS and DOA, its cold resistance is also better.
The volume resistivity of 4.DOTP is 10-20 times higher than that of DOP, and its mobility is excellent.
5., because DOTP does not contain o-phthalate two formate, it is not an environmental friendly plasticizer in the range of 16 16 kinds of plasticizers containing o-phthalic acid in the European Union and other countries.
Phosphoric acid two benzene isooctyl ester (C20H27O4P) is colorless transparent oil like liquid, mainly used as flame retardant plasticizer, almost compatible with all industrial resins and rubber, and has better compatibility with PVC. Low volatility, Naisai and good weather resistance, and the adjacent benzene two formic acid ester plasticizer with the use of the product can be improved toughness and weatherability; for PVC film, can improve the tensile strength, improve the resistance to abrasion resistance.
Phosphoric acid two phenyl isooctyl ester is a flame retardant plasticizer, almost compatible with all industrial resins and rubber, and has better compatibility with polyvinyl chloride. Low volatility, Naisai and good weather resistance, and the adjacent benzene two formic acid ester plasticizer with the use of the product can be improved toughness and weatherability; for PVC film, can improve the tensile strength, improve the resistance to abrasion resistance. It can also be used as a flame-retardant plasticizer for synthetic rubber.
Phosphate type plasticizers, including two phenyl isooctyl phosphate, are characterized by flame retardancy and strong antibacterial properties. The highest yield of trimethyl benzoic acid (TCP), phosphoric acid toluene two benzyl ester (CDP) and phosphoric acid three benzyl phosphate. The toxicity of phosphates is generally stronger, and two benzisyl phosphate is the only phosphate that is allowed to be used in food packaging materials.
Toluene phosphate two phenyl ester (flame retardant CDP) is mainly applied to PVC, VC copolymer, polyvinyl acetal, nitrocellulose, cellulose acetate, butyl acetate cellulose, natural and synthetic rubber and other flame retardants, plasticizers, gasoline and lube oil additives.
Toluene phosphate two phenyl ester is a colorless or yellowish transparent liquid with a slightly phenolic flavor. It is stable and non-volatile, and has good flame retardance, plasticization, oil resistance, aging resistance, electrical insulation and processability. It is soluble in organic solvents and slightly soluble in water.
Toluene phosphate two phenyl ester is suitable for polyvinyl chloride, vinyl chloride copolymer, polyvinyl alcohol acetal, nitrocellulose, ethyl cellulose, cellulose acetate butyrate and so on.
