2017-12-19 10:54:27
Polyol ester plasticizer mainly include dipentaerythritol ester and ethylene glycol cheese.
Polyol ester plasticizer dipentaerythritol ester has low volatility, good extraction resistance, difficult thermal decomposition and oxidation and good electrical insulation property. It is excellent heat resistant plasticized Liu, suitable for high temperature wire insulation formulations, but expensive. The cold resistance of polyol ester plasticizer is very good, but its color and lustre are deep and volatile.
(1) pentaerythritol ester (PCB). Dipentaerythritol esters can be divided into ether and ester groups. These two kinds of four quaternary pentaerythritol esters are light yellow viscous oily liquid. They can be dissolved in organic solvents and insoluble in water.
(2) ethylene glycol 59 (0259). A light yellow transparent liquid.
Dipentaerythritol (referred to as double cropping) with long carbon chain, high molecular weight, stable ether bond, with oxygen atoms as the center to form a typical star structure, a plurality of hydroxyl esterification, nitration, halogenation molecules, form functional complexes with unique properties, are widely used in the polymer industry printing, paint industry, textile industry and aerospace industry etc..
The application of polymer in the field of polymer. A plurality of hydroxyl groups in the molecules and two different unsaturated acids of all or part of the esterification reaction, to generate various types of double cropping of unsaturated ester monomer, constitute the basis for application in polymer, can be directly added to polymers, additives used to form, improve the performance of the polymer, can be copolymerized with other monomers, generating new polymers, use of new derivative.
Polymerized as a new polymer as a monomer. Two or three or four double pentaerythritol ester acrylic ester as crosslinking agent and other unsaturated compounds of graft copolymerization, preparation of porous polymer is excellent container of blood or biological products, can effectively improve the blood or biological product shelf life, known as "polymer compatibility with blood. The polymerized dipentaerythritol ester acrylate can be coated with tussah magnetic material to prepare magnetic recording materials.
Containing double bond dipentaerythritol ester carboxylic acid in the light absorbing material or light polymerization agent, can absorb ultraviolet light or electron beam polymerization, to create light polymerization layer or polymeric mold; dipentaerythritol ester and glycolide and lactide under the action of catalyst, the poly ester is a new type of biological degradable material polymerization can be used for food and pharmaceutical packaging, is expected to solve the problem of "white pollution".

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.
With vitamin E and a small amount of other components, such as acid crosslinking agent, it can also be made into a safe and safe polymer material with good thermal stability. Double pentaerythritol ester and epoxy ethane or propylene oxide reaction, the average molecular mass of the polyhydroxy etherate 100-25000, tensile strength and impact toughness is high, is a good bonding material, is used in engineering plastics, increase the impact toughness and strength.
Double pentaerythritol ester acrylate with ethylene oxide, propylene oxide modified polymer films prepared for coated alkali metal such as lithium electrode, electrode as a protective film; double pentaerythritol ester methyl acrylate and the average molecular weight of 400-1000 methyl ethyl malonate ester two mixed with light initiator polymerization, high temperature resistant 150-200? The adhesive used for bonding semiconductor and electronic components, change the current high temperature, easy to fall off the defects of electronic components.
As a heat stabilizer for PVC and PET. PVC is an amorphous polymer with a glass transition temperature of 80? Plasticizing temperature 150-170?? the molecular structure is unstable. It starts to degrade at 100 degrees Celsius, and accelerate the degradation at 150 degrees Celsius. If we do not inhibit the production of hydrogen chloride, the degradation will intensify. Some heat stabilizers and some auxiliary agents are often added to the finished product to improve the stability of PVC. Polyhydroxy in dipentaerythritol ester can chelate metal chlorides, inhibit the catalytic effect of metal compounds on the thermal degradation of PVC, and hydroxyl also has the function of replacing allyl chloride and capturing HCl.
Single and double pentaerythritol esters are one of the auxiliary heat stabilizers. They are nontoxic formulations with calcium or zinc stabilizers. They are mainly used in PVC and other chlorine containing polymers. By esterifying the partial hydroxyl group in the bis - pentaerythritol ester, the phase solubility of PVC is adjusted to increase the transparency of PVC.
So, the derivatives of dipentaerythritol ester particles or double pentaerythritol ester is often added abroad in PVC to improve the stability of PVC, and reduce PVC film color; unsaturated acid ester copolymer of vinyl chloride monomer and dipentaerythritol ester C5-C22, PVC resin fluidity was improved, with better low temperature, high speed machining performance; phosphorus thermal stabilizer of dipentaerythritol ester carboxylic acid ester is used instead of two yuan, added to the PET mixing, to avoid the PET decomposition of acetaldehyde and other harmful substances in the heat processing, improve the safety of the human body, used for manufacturing equipment in close contact with the human body, such as children's toys etc..
