PVC waterproof material plasticizer
Polymer PVC waterproof material plasticizer is a kind of low viscosity and good mobility resistance, and is used in high soft and soft PVC products. A low viscosity ester drunk phthalate plasticizer, adding the PVC waterproof material of plasticizer PVC waterproof material and pipe products more suitable for use in alkaline environment and grease; PVC waterproof material of plasticizer for polylactide molded products have good flexibility and resistance to flow, and with a high degree of safety and good biodegradability.
Two cyclohexane carboxylic acid ester plasticizer is a kind of aliphatic compounds, used in food packaging, medical equipment and toys are safe; non-toxic, biodegradable plasticizer Benzoflex2888, mainly based on the consideration of the development of non-toxic plasticizer and the requirements of environmental protection, health products for children with high requirements of injection molding products, and leading plasticizer phthalate isononylphtalate two formic acid (DINP) compared with the characteristics of products, non-toxic elastic plasticized biodegradable.
Plasticizer (2,2,4- three -1,3- two isobutyl methyl pentanediol), is suitable for a variety of resin with special plasticizer, not containing benzene derivatives, used in toys, pharmaceutical and food packaging plastic products, compared with DOP, can improve the color and PVC plastic sheet of polyethylene film stiffness and stain resistance.
Foreign major plasticizer production enterprises in recent years has also developed a series of trimellitic acid ester plasticizer and bio chemical plasticizer, trimellitic acid ester plasticizer is mainly used for wire and cable materials heat-resistant additives, also used in civil and military high-tech plastic lubricating products, bio chemical plasticizer is mainly composed of vegetable oil derivatives, such as epoxy soybean oil, linseed oil and epoxy resin acid salt, can be found in the soft PVC as the plasticizer, the biggest feature is non-toxic and environmentally friendly.
In high performance soft PVC using metallocene based polyolefin elastomer (POE) and PVC resin suspension grade alloy instead of liquid plasticizer, PVC/POE alloy materials in extreme cold and hot conditions, soft PVC product performance is much better than the traditional, the material can not be used for liquid plasticizer leaching in the high-end market, such as medicinal film and auto parts etc..
In recent years, Chinese plasticizers have made great achievements in scientific research and industrialization, mainly in the following aspects:
Jinling Petrochemical Research Institute, using phthalic anhydride and 2- propyl -1- heptanol as raw materials, has synthesized a new plasticizer, o-phenyl two formic acid two (2- propyl heptane) ester (DPHP), all properties are close to or surpass those of commonly used plasticizers. In addition, the hospital also with phthalic anhydride, ethylene glycol monobutyl ether as raw material, in the presence of four butyl titanate catalyst, esterification reaction for the synthesis of antistatic plasticizer phthalate - two formic acid two (2- ethoxy ethyl) ester (DBEP), compared with DOP, DBEP can effectively reduce the viscosity of PVC paste, improve the stability of PVC paste viscosity, tensile strength and elongation at break increased, but also can significantly improve the antistatic properties of products.
In addition to the above results, a new non-toxic plasticizer, acetic acid citric acid three butyl ester (ATBC), has been successfully tested in the hospital, and the technical index has reached the standard of similar products abroad. DCHP is a kind of moisture-proof plasticizer. It can shrink the surface of plastic with the use of other plasticizers, and it can prevent moisture and prevent volatilization of plasticizers. Two
The basic information of two octyl terephthalate (plasticizer DOTP)
Chinese Name: two octyl terephthalate
Synonyms: two Chinese terephthalate (2- ethylhexyl) ester; dioctyl terephthalate two; terephthalic acid two 1,4- benzene carboxylic acid isooctyl ester; two bis (2- ethylhexyl) ester; terephthalic acid two (2- ethylhexyl) ester; dioctyl terephthalate (DOTP); two double 2= ethylhexyl terephthalate; bis (2- ethylhexyl) terephthalic acid, plasticizer DOTP
English Name: Dioctyl terephthalate
English synonyms are: Di- (2-Ethylhexyl) Terephthalate; Di (2Ethylhexyl) Terephthalate; Kodaflexdotp; Terephthalicacid, Bis (2-Ethylhexyl) Ester; Bis;; ";"
CAS: 6422-86-2
Molecular formula: C24H38O4
Molecular weight: 390.56
EINECS: 229-176
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.
Due to the extremely low toxicity, the United States, Japan, Italy and Germany are licensed for food packaging materials, powder as plasticizer, with the performance and use of the ordinary liquid plasticizer can not be replaced, the demand is estimated to reach more than 2kt/a, the current domestic capacity of about 300t/a, most rely on imports.
Hu Yingxi and others in the Department of chemical engineering of Beijing Institute of Petrochemical Technology studied the synthesis of o-benzoic acid two cyclohexyl ester by transesterification under the condition of solvent-free, using methyl ester and cyclohexanol as raw materials and organotin as catalyst. The cold resistant plasticizer sebacic acid two hexyl ester is commonly used as plasticizer for agricultural film, electric wire, sheet, artificial leather, outdoor water pipe, frozen food and medical packaging plastic due to its low volatility, colorless, non-toxic and low viscosity.
The traditional synthesis method of the ester is the esterification reaction of sebacic acid and hexanol with sulfuric acid as the catalyst. Zi Junfeng and others of the Department of chemistry of Xuchang University have synthesized two hexyl sebacate with silicon tungsten heteropoly acid as the catalyst, sebacic acid and hexanol as raw materials.
Wang Shuqing et al. Of Nantong University School of chemistry and chemical engineering, using the condition experiment method, used nonarboxylic acid and hexanol as raw materials to directly synthesize the cold resistant plasticizer azelaic acid two hexyl ester.
A mixture of four isopropyl titanate and four butyl titanate was used as the catalyst in the Chemical Engineering Department of Changzhou Institute of Engineering Technology to catalyze the esterification of 810 phthalic acid two formate. The Institute of chemistry and chemical engineering, Xiangtan University, uses organic phosphoric acid as a condensation catalyst to synthesize special plasticizer, isooctyl Nitrobenzoic Acid. The process is simple and the product is easy to separate. It fills the gap in the domestic and has a good industrial prospect.
