Abstract

The invention provides a composite reinforced PET material. The composite reinforced PET material is prepared from the following raw materials by weight percent: 60 to 65 percent of PET resin slices, 1.2 to 1.8 percent of inorganic particles, 10 to 14 percent of composite flame retardant and 22 to 26 percent of glass fibers. The PET material is reasonable in raw material consumption, simple in preparation process and excellent in mechanical performance, heat performance, flame retardant performance and machining performance, the application value in the production of the PET sheet material is high, and the market prospect is wide.

Description

technical field [0001] The invention relates to a PET material, in particular to a composite enhanced PET material, which belongs to the technical field of plastic materials. Background technique [0002] PET resin chip PET is an important engineering plastic, which has excellent physical and mechanical properties in a wide temperature range, and can still maintain excellent electrical insulation properties under high temperature and high frequency. The PET sheet produced by it is widely used In electronics, food, medicine, office supplies, toys and other industries. However, PET itself has problems such as poor gas barrier properties, slow molding crystallization speed, high water absorption, poor impact performance, and poor flame retardancy, so the scope of use is limited, so it is necessary to modify the PET material to obtain conformity PET material for various application requirements. [0003] At present, in the modification of PET materials, methods such as filling...
