Abstract

The invention relates to a high-performance uniform-shrinkage-rate PET composite material and a preparation method thereof. The PET composite material consists of the following components in parts by weigh as follows: 80-100 parts of PET, 6-10 parts of basalt fibers, 10-16 parts of mica powder, 0.1-0.5 part of an antioxidant and 0.1-0.3 part of a lubricant. According to the invention, the prepared PET composite material has excellent mechanical properties and uniform lateral and longitudinal shrinkage rates, ameliorates the problems that the impact property of PET composite materials is low and the shrinkage rate of the PET composite materials is not uniform. positive nitrogen ions N<+> are introduced to the surfaces of the basalt glass fibers through plasma processing, so that the active sites of the surfaces are increased, and the surface polarity is improved, and accordingly the attractive force and adhesive ability of the glass fiber surfaces are increased and the compatibility of the glass fibers and PET matrix is improved.

Description

Technical field [0001] The invention belongs to the technical field of polymer materials, and particularly refers to a high-performance PET composite material with uniform shrinkage rate and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) is a common macromolecular polyester resin. It has good optical properties and weather resistance, but at the same time it also has a small notch impact strength and aspect ratio shrinkage.
