Polymerized plasticizer
Using the plasticizing agent and plasticizing paste process and paste PVC resin, we can get ideal rigid products, such as toys and shoes heel, and think that some industrial products with high stiffness must be high. Polymerized plasticizers are especially suitable for finishing the surface of steel, wood, fabric or PVC floor tiles, so as to enhance pollution resistance, wear resistance, solvent resistance, water resistance and prevent expansion due to water absorption and solvent.
Polymeric plasticizers are widely used in oil and gas pipes, cables, waterproofing materials, artificial leather, shoe material, high temperature resistant wire coating layer, water seal, all kinds of equipment (including refrigeration equipment, motor vehicles) of the gasket, molding; senior interior decoration; electrical tape; oil resistant special products such as gasoline.
Reoplex high molecular weight, usually 1000~8000, they are volatile in the process of low in manufactured goods in the plasticizer is not easy to be water, oil and solvent extraction, and the migration of small, high temperature resistant, can maintain the good quality of manufactured goods and the service life is long, the haplotype increased plasticizer has many advantages. Therefore, it is called a durable plasticizer (permanent plasticizer).
The polymer plasticizer has better compatibility with the resin, less volatile and mobility, more resistant to extraction, less toxicity and better heat resistance. However, due to the complex structure of polymerized plasticizers, the same compounds have the same composition, but the molecular weight difference is very large, and the viscosity range is large. In addition, the synthetic methods of polymerized plasticizers involve the patented technology of producers. Therefore, manufacturers often report their product names with commodity brands, but seldom disclose the specific structure and chemical composition of their products.
The relative molecular mass of the polymeric plasticizer is usually controlled between 500~8000. The relative molecular mass of 10000~50000 will become a crystalline solid and can not be used as a plasticizer.
But there are many substances in the 500~8000 between the relative molecular weight, such as unsaturated natural glycerides of epoxidation, pentaerythritol and two pentaerythritol four esters and six alcohols.
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.
Packing method:
200KG/ net galvanized steel drum (a small pallet loaded 16 tons), 1000KG/IB (a small barrel loaded 18 tons or 23 tons of ISOTANK).
Polymeric plasticizer for diacids and diols condensation polyester ends with a yuan of alcohol or acid blocking modification. It is a hot spot in the research and development of plasticizers in recent years. Mainly due to PVC product performance of some special applications more demanding, haplotype of traditional varieties of plasticizer cannot meet the heat resistance, weatherability and durability requirements, increase the molecular weight is the key to solve these technical problems, is also in line with the overall trend of development of varieties of plastic additives.
Practice has proved that polymerized plasticizer has many advantages, such as large molecular weight, volatile resistance, extraction and migration performance, heat stability and wide viscosity range. In recent years, many varieties have made significant progress in improving processability and cold tolerance. The polymer plasticizers of 2- butanediol, such as 1 in Japan, have the advantages of low viscosity and good compatibility.
Usually used for the preparation of polymeric plasticizer acid types include glutaric acid, adipic acid, azelaic acid, sebacic acid and phthalic acid two, which is more adipic acid, azelaic acid and sebacic acid important. Recent studies have shown that the glutaric acid type plasticizers are particularly prominent in the resistance to migration and weatherability.
The aggregate plasticizer output in the US and Japan accounts for 12% to 13% of the total plasticizer output. However, at present, there are only a few products in China, and the product quality and production scale are quite different from those in other countries. With the increasing variety and grade of plastic products, the demand for polymerized plasticizers will continue to increase. Research and development of polymeric plasticizers will have broad prospects.
Polymerized plasticizers are excellent heat-resistant and durable plasticizers due to their large molecular weight, low volatility, small migration, oil resistance and soaping water extraction. The disadvantage is that the plasticizing efficiency is slightly poor, the viscosity is large, and the processability and low temperature are not good. Widely used in oil resistance, high temperature resistant special products, such as: oil resistance, high temperature, high humidity and non migrating cable materials, high temperature resistant wire cladding layer, insulating material, contact for coating, rubber, polystyrene, ABS and organic solvent close products, such as: electric wire, Refreigerator seal pipe and equipment. Oil resistant rubber boots and gloves for flooring, in anti pollution products. In contact with food, it can be used for packaging film, soft drink hose, bottle cap gasket and so on. As the impact modifier used in the hard PVC formula, it can improve the brittleness and toughening effect of PVC resin.
