Description

technical field

[0001] A phthalic acid polyester plasticizer and a preparation method thereof relate to the technical field of polyester plasticizers. Specifically, it relates to a phthalate polyester plasticizer with good extraction resistance, good insulation performance, good thermal stability and substantially non-toxicity. Background technique

[0002] Plasticizers are the most widely used plastic additives, which play an important role in improving the mechanical properties of plastic and rubber products. At present, the plasticizer industry has formed one of the important fine chemical industries based on petrochemical industry and mainly based on phthalic acid monomer esters.

[0003] Since most of the currently used plasticizers are monomeric esters with relatively low molecular weight and poor compatibility with polymer materials, they are easily extracted by oils or organic solvents, which affects the application performance of products. This kind of problem is ...
