Abstract

The invention relates to the technical field of engineering plastics, in particular to a preparation method of a carbon fiber reinforced terpolymer alloy. 20 to 50 parts of a styrene-acrylonitrile-butadiene terpolymer; 5 to 15 parts of a styrene-acrylonitrile binary copolymer; and 10-30 parts of carbon fiber. The invention has the beneficial effects that the carbon fiber reinforced resin has high specific strength, light weight, strong uniformity and insensitivity to the environment, can achieve the tone consistent with that of wood, is an excellent substitute material for wood, and has a good application prospect in numerous thermoplastic resins. The carbon fiber reinforced polycarbonate / acrylonitrile-styrene-butadiene terpolymer alloy has the advantages of low shrinkage rate, low loss modulus, excellent tone quality and the like, can be used for preparing a carbon fiber reinforced material with higher mechanical strength, optimizes the ABS type and the carbon fiber type, and can be used for preparing the carbon fiber reinforced material with higher mechanical strength. The content of a rubber phase in ABS and the grade of carbon fibers have very high influence on the mechanical strength, the fluidity and the warping degree of the product.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a method for preparing a carbon fiber reinforced terpolymer alloy. Background technique [0002] Engineering plastics can be used as engineering materials and plastics that replace metal manufacturing machine parts, etc. Engineering plastics have excellent comprehensive performance, high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can be used in harsh chemical and physical environments for a long time, and can replace metals as engineering structural materials. , but the price is more expensive and the output is smaller. [0003] CN201611012163 patent proposes a method for preparing carbon fiber reinforced PC / ABS material, which can better improve the bonding force between carbon fiber and matrix resin, but the strength and modulus of the prepared material are low. [0004] CN107474510 A patent proposes ...
