Abstract

The invention belongs to the field of high polymer materials and discloses a polyester-reinforced high polymer composite material and a preparation method thereof. The polyester-reinforced high polymer composite material comprises the following components in parts by weight: 44-67 parts of polyester resin, 7-14 parts of benzene sulfonyl chloride, 5-11 parts of triisopropyl aluminate, 27-39 parts of polyethersulfone resins, 4-8 parts of di-iso-decyl phthalate and 3-7 parts of carbodiimide. The preparation method comprises the following steps: heating the various components, mechanically mixing to be uniform, performing twin-screw extrusion, preserving the temperature after extrusion, and cooling to room temperature, thereby obtaining the polyester-reinforced high polymer composite material.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a polymer composite material and a preparation method thereof, in particular to a polyester-reinforced polymer composite material and a preparation method thereof. Background technique [0002] Polymer materials are materials based on polymer compounds. Polymer materials are divided into rubber, fiber, plastic, polymer adhesives, polymer coatings and polymer-based composite materials according to their characteristics. [0003] Polymer materials are organic compounds, except for carbon atoms, other elements are mainly hydrogen, oxygen, nitrogen and so on. Stable structures can be formed between carbon atoms and between carbon atoms and between carbon atoms and atoms of other elements. Some organic structures (also known as functional groups) can be replaced in the polymer to change the properties of the polymer. Polymer materials include three major synthetic materials, namely pl...
