Problems solved by technology

[0003] In the automotive industry, there are many kinds of automotive rubber and plastic accessories, such as wipers, sealing accessories, shock-absorbing air spring coils, toothed cutting belts, etc., and the application of plasticizers in many places is indispensable. Long-term consumable products, and many places are in a high-temperature operating state during use, which has high requirements for accessories, in terms of strength, tensile resistance, high temperature resistance, and wear resistance. There are further high-standard requirements for plasticizers used in rubber and plastic parts. At present, research on plasticizers specifically for rubber and plastic parts in automobiles has not been reported.

Abstract

The invention discloses a method for preparing a plasticizer used in rubber and plastic parts of automobiles. Aiming at the defects of the existing plasticizers, citric acid, phthalic anhydride, dibasic acid esters, epoxy plasticizers, multi-component Alcohols, hydrogen peroxide, dioctyl terephthalate, anti-wear agents, lubricants, tackifiers and other raw materials, the plasticizer prepared by the present invention used in rubber and plastic parts of automobiles not only has low cost, It has the advantages of high temperature resistance, good plasticizing performance and stable performance, and after being applied to automobile rubber and plastic parts, the finished product has good tensile performance, good abrasion resistance, good flame retardancy, and has certain hardness and flexibility. The advantages of the invention break through the defects of traditional plasticizers used in the automobile industry, and have strong practical value. In addition, the preparation method is simple and easy to operate, and the degree of industrialization is high.

Description

technical field [0001] The invention relates to a preparation of a plasticizer, in particular to a preparation method of a plasticizer used in automobile rubber and plastic parts.
