Aliphatic dibasic acid ester cold resistant plasticizer
Aliphatic dicarboxylic acid esters of cold resistant plasticizer because of its excellent low temperature performance, strong impact resistance, high plasticizing efficiency and good viscosity characteristics, rapid development in recent years, the demand increased year by year, but because of the aliphatic dibasic acid ester cold resistant plasticizer PVC and poor compatibility, can only be used as cold auxiliary plasticizer.
Aliphatic dibasic acid ester cold resistant plasticizer resistant performance is decided by its own structure, which belongs to the straight chain aliphatic dicarboxylic acid esters of methylene (-CH2-) as the main plasticizer, can keep the movement of polymer chains at low temperature, which has excellent cold resistance.
Adipic acid two (2- ethyl) hexyl ester (DOA). DOA as a good cold resistant plasticizer of PVC, products to give excellent soft, in plastisol, low initial viscosity, good viscosity stability, and have certain heat resistance and light resistance and water resistance and no toxicity. And DOP etc. the main plasticizer for hardy agricultural films, wire, sheet, artificial leather, outdoor water and frozen food packaging film. It is also used as a plasticizer for many synthetic rubber and plasticizers, such as nitrocellulose, ethyl cellulose and other resins.
Sebacic acid two octyl (D0S). The cold resistance of two octyl sebacate is excellent, but its heat resistance and weatherability are poor. The plasticizer is mainly used for cold resistant products, such as PVC agricultural film, low temperature resistant packaging, artificial leather, sheet and plate. In addition, it is widely used in wire and electric wire sheath, soft protective layer and cold resistant coating.
Two aliphatic dicarboxylate (aliphatic dicarboxylic acid ester) is composed of two yuan of aliphatic carboxylic acid and dihydric alcohol by esterification reaction and the product. It includes succinic acid ester, glutaric acid, hexandiacid ester, symplectic two ester, decyl two ester, twelve alkyl two ester, thirteen alkyl two ester and so on.
At present, this kind of plasticizer mainly adipate (adipic acid ester), nonyl ester (Azelaic two acid ester two (sebacic) and acid ester decyl ester), one of the most widely used, the largest output for two varieties of adipic acid (2- ethylhexyl) ester [di- (2-ethylhexyl) adipate, DEHA].
Unsaturated fatty acid ester two yuan (unsaturated aliphatic diacid ester) with maleic acid ester (maleic acid ester, maleic, acid, ester) (fumaric acid ester) fumarate and itaconate (itacon-ic acid ester). These esters contain double bonds, which can be copolymerized with vinyl monomers, but are used as internal plasticizers. They are traditionally classified as reactive plasticizers.
Plasticizer is usually a "solvent like" substance. When added to plastics, resins or elastomers, it can improve their workability and increase plasticity, flexibility, tensile or expansive substances. Adding plasticizer can reduce the melt viscosity, vitrification temperature and elastic modulus of plastic, but will not change the basic chemical properties of plasticized substances.
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).
Plasticizers can change the properties of polymers, which is generally considered to be:
(1) plasticizer isolates the distance between macromolecules of polymer, and weakens the attraction force between polymer molecules, which weakens the van Edward force between resin molecules.
(2) nonpolar plasticizers added to the nonpolar polymers cut off the polar parts of polymer molecules, resulting in no polar connection, and destroyed the dipole dipole interaction between polymers.
(3) the plasticizer is combined with a couple of resins instead of a chemical force (covalent bond).
Therefore, when mixed with resin and mixed without chemical reaction, it can change some properties of the resin after mixing, and it can be retained in plastic products for a long time, and the substances that change the properties of plastic products can be used as plasticizers. The substances that have these functions are mostly liquid organic compounds or low melting point solids. They have to be polar, compatible with resin, stay in resin for a long time, and have good performance, high efficiency and low price for the resin.
The technology and application of plasticization originated from the original inventions of human beings. In ancient times, water clay ceramic, gelatin in water system sweet snacks, soft leather with oil and gas for asphalt paving materials, cellulose nitrate plus tar roof materials, the various products in the water, oil, tar, which played a plasticizing effect, which is called the various products in the plasticizer. In the course of more than a century, with the development of plastics and rubber industries, more than 20000 plasticizers have been recorded in the literature in 1943. More than 150 kinds of industrial production.
