Problems solved by technology

[0005] Technical problems to be solved: In order to deal with the poor thermal stability of PVC products with the traditional calcium / zinc heat stabilizers on the market, traditional phthalate plasticizers have persistent physiological toxicity, epoxy fatty acid methyl esters The plasticizer has the current situation of high mobility and high volatility. The present invention uses methyl laurate as a raw material to provide a tung oil source epoxy plasticizer product with a heat stabilizer function and its preparation method and application. The product has low volatility and low mobility. It can effectively improve the thermal stability of PVC products while imparting good plasticizing properties to PVC products. It can replace or partially replace dioctyl phthalate (DOP ), dioctyl terephthalate (DOTP), epoxy fatty acid methyl ester and other plasticizers

Abstract

The invention provides a tung oil source epoxy plasticizer product having the function of a heat stabilizer, a preparation method thereof and an application thereof. According to the technical scheme of the invention, dienophile is uniformly mixed up and then methyl eleostearate is added. The dienophile and the methyl eleostearate are subjected to Diels-Alder addition reaction, and then fractions are collected in the vacuum condition so as to obtain tung oil source polybasic acid esters including tung oil source dibasic acid dimethyl ester, tung oil source ternary acid trimethyl ester and the like. With the existence of hydrogen peroxide, formic acid, phosphoric acid and the like, one part of unsaturated double bonds in the structures of the tung oil source polybasic acid esters is subjected to epoxidation, so that the tung oil source epoxy plasticizer product can be obtained. According to the technical scheme of the invention, methyl eleostearate is adopted as a raw material, and the obtained tung oil source epoxy plasticizer product is low in volatility, small in mobility and good in compatibility with polyvinyl chloride resin and the like. Meanwhile, polyvinyl chloride products are enabled to be good in plastification effect, and the heat stability of PVC products is effectively improved at the same time. The tung oil source epoxy plasticizer product can be used to replace or partially replace plasticizer products including dioctyl phthalate, dioctyl terephthalate, epoxidized fatty acid methyl ester and the like.

Description

technical field [0001] The invention belongs to the field of plastic additives, and in particular relates to a tung oil-sourced epoxy plasticizer product with the function of a heat stabilizer and its preparation method and application. Background technique [0002] Polyvinyl chloride (PVC) resin is a thermoplastic linear polymer produced by free radical polymerization of vinyl chloride monomer, and is one of the five general-purpose resins in the world. Compared with other general-purpose resin products, PVC products have the advantages of being more energy-saving and low-carbon. All countries are optimistic about the development potential of the PVC industry and its benefits to the ecological environment. At present, the PVC industry is developing rapidly all over the world with broad prospects. At present, the production capacity, output and consumption of my country's PVC industry rank first in the world, but from the perspective of per capita consumption, there is stil...
