Epoxy plasticizer is a kind of plasticizer produced by epoxidation of vegetable oil or unsaturated fatty acid. The main epoxidized linseed oil and unsaturated fatty acids epoxidized soybean oil, epoxidized butyl ester, such as epoxy, epoxy octyl oleate, oleic acid decyl ester epoxy. Most epoxy plasticizers have thermal stability and are often combined with other stabilizers to play a stabilizing effect. The epoxidation of plant oil has good anti - Extraction and anti - mobility. It is mainly used as PVc plasticizer and stabilizer, often not the main plasticizer. Nontoxic epoxidation of soybean oil and flaxseed oil can be used as a plasticizer for contact food.
The epoxy plasticizer (epoxy plasticizer) is a substance that has an epoxy gene in the molecular structure of organic compounds.
In the industrial processing of PVC resin, it not only has the plasticizing effect of PVC, plasticizer and epoxy group in the molecule can also absorb hydrogen chloride released by PVC molecular heat and light degradation, the PVC chain of active chlorine atom is stable, thereby preventing the continuous catalytic decomposition of PVC, to stabilize the role of prolonging service life of PVC products.
The addition of 2~3 epoxy plasticizers in PVC resin can play a stable role in the stability of light and heat. Adding 5 phr can significantly improve the cold resistance in plastic film mulching film. When used with polyester plasticizer, it is most suitable for making filling for freezing equipment and motor vehicles. Epoxy resin (such as bisphenol A two glycidyl ether) has the function of antiscaling, besides the heat stability.
Vegetable oils containing a large number of unsaturated bonds, such as soybean oil and flaxseed oil, and other natural products, such as Dole oil, are important raw materials for epoxy plasticizers. The double bonds in these oils are oxidized by epoxidation, and the epoxy oil can be used as plasticizers.
The toxicity of epoxy plasticizers is very low, and many countries have allowed it to be used as packaging materials for food and medicine. Therefore, the epoxy plasticizer occupies an important position in modern plastics.
Epoxy plasticizer compounds can be divided into the following types because of their different structure and epoxy position.
(a) including bisphenol A two glycidyl ether.
(b) polyallyl glycidyl ether (polyallyl glycidyl ether). These two types of epoxy groups are located at the end of the fatty carbon chain, and these plasticizers are the best of the epoxy plasticizers.
(c) for epoxidation of olefin, an epoxy group at the end group and one inside the structure, the epoxy plasticizer is less efficient.
(d) there are epoxidation of plant oils, and their efficiency is worse than (a), (b), (c).
(E), (f), (g) are all kinds of compounds containing alkyl or ester based epoxy groups on cyclohexane ring, and this kind of epoxy plasticizer is most inefficient.
The epoxy plasticizer contains a small amount of residual unoxidized unsaturated structure, because the compatibility with PVC is poor. Because of the high price, the function of the stabilizer is mainly used in the process of plastic processing, which can only be used as an auxiliary plasticizer. The general dosage is only 5%~25% of the total plasticizer, and 2~10phr is used in the soft products.
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).
The thermal stability and light stability of the epoxy plasticizer are very good. It can not only prevent the products from coloring in processing, but also make the products have good weatherability.
Durability (resistance to volatilization, solvent extraction, resistance to migration)
The difference of the volatile molecular weight of the epoxy plasticizer varies greatly. The properties of water extraction, oil resistance and volatilization loss of epoxy plasticizer are better.
The performance of the epoxy plasticizer is not very good, and it has a great influence on other acids, except for the erosion of hydrochloric acid.
Most of the epoxy plasticizer molecules contain linear structure, so they have good cold resistance as aliphatic two ester (DOS) and aliphatic ester. There is a significant difference in the poor cold resistance of the compounds with benzene rings in the molecular structure. 5 copies can be added in the plastic film significantly improve the weatherability of plastic sheeting.
The toxicity of epoxy plasticizers is low, and the epoxidized soybean has been allowed to be used in plastic products in contact with food.
Epoxidized soybean oil (ESO) is a widely used PVC auxiliary plasticizer and stabilizer, good heat and light stability, good compatibility, low temperature flexibility, low volatile, anti extractable, and has good electrical insulation properties, commonly used in the PVC film, sheet and artificial leather. (2) epoxy fatty acid butyl ester is an auxiliary plasticizer and stabilizer for PVC. It has good heat resistance and weatherability, and has good compatibility with PVC. Because of fatty acid composition, butyl epoxy ester has epoxy stearic acid butyl ester, epoxy soybean oleic acid butyl ester, epoxy bran butyl oleate, epoxidized oleic acid butyl ester and other varieties.
