Problems solved by technology

This type of polyarylether nitrile resin has higher mechanical strength and heat resistance, but its processing fluidity becomes poorer, and it is more difficult to add glass fiber fillers, so it is necessary to plasticize it
Although commonly used plasticizers can improve the fluidity of polyarylether nitrile, they often reduce the overall performance of polyarylether nitrile due to poor compatibility and heat resistance.

Abstract

The invention belongs to the field of high polymer materials, particularly relating to a poly (arylene ether nitrile) composite material and a preparation method thereof. The invention aims to solve the first technical problem of providing the poly (arylene ether nitrile) composite material with high performance and wear resistance. The poly (arylene ether nitrile) composite material of the invention comprises the following components in parts by weight: 40-70 parts of poly (arylene ether nitrile), 10-40 parts of filling, 3-10 parts of phthalocyanine prepolymer and 0-7 parts of anti-wear additive. The phthalocyanine prepolymer of the invention has the effect of plastification and improve the interface action between a resin system and fibers and between the resin system and the anti-wear additive, and the mechanical strength, abrasive resistance and abrasive resistance of the composite material.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and in particular relates to a polyarylether nitrile composite material and a preparation method thereof. Background technique [0002] Polyarylene ether nitriles (PEN) is a kind of polyarylene ether with nitrile groups on the side chain, which has high heat resistance, flame retardancy, mechanical strength, radiation protection and good creep resistance, etc. Excellent characteristics. It has a wide range of uses in electronic packaging materials, precision machinery, bearings and auto parts. [0003] In order to further improve the mechanical strength, wear resistance and heat resistance of polyarylether nitrile, it is very effective to increase its molecular weight and adjust its molecular structure. The research group of Professor Liu Xiaobo from the University of Electronic Science and Technology of China has developed a series of high-performance, high-viscosity polyarylether nitri...
