Abstract

Polyethylene glycol terephthalate (PET) is an important compound in polyester. PET has the advantages of high rigidity and strength, creep resistance and high size stability, is an important fiber and engineering plastic and has the defects of low crystallization rate, difficulty in contour machining, high molding temperature, long production period and poor impact property. The invention aims to provide a safe polyethylene glycol terephthalate (PET) material without influence on the mechanical properties of the materials. The montmorillonite toughened and modified polyethylene glycol terephthalate material comprises the following raw materials in parts by weight: 70-90 parts of polyethylene glycol terephthalate, 2-10 parts of organic montmorillonite, 2-10 parts of ethylene propylene terpolymer, 2-10 parts of glycidyl methacrylate, 2.0-3.0 parts of antioxidant, 2.0-3.0 parts of light absorber and 0.5-1.5 parts of diffusion oil.

Description
