Abstract

The invention belongs to the technical field of modification of high molecular composite materials and in particular relates to a fiber-enhanced polypropylene material and a preparation method thereof. The polypropylene material takes high-crystallinity homopolymerized polypropylene as a basic component and polyketone resin is added to improve the wear resistance and mechanical properties of the material; compound fibers composed of chopped carbon fibers and aluminum fibers are added, and graphene is added to improve the mechanical strength and heat and electricity conductivity of the material; a compatibilizer is added to improve the binding force between raw materials, so that the mechanical properties of the material are improved; and an antioxidant is added to improve the anti-ageing performance of the material and a lubricant is used for reducing the friction generated in a material processing process. The material has the advantages of high strength and high modulus, heat conduction and electricity conduction, high temperature resistance, excellent size stability and the like, and can completely meet the functional requirements of automobiles, machines and chemical heat exchange parts on the material under a severe environment.

Description

technical field [0001] The invention belongs to the technical field of modification of polymer composite materials, and in particular relates to a fiber-reinforced polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a thermoplastic resin with excellent performance. It has many advantages such as high cost performance and convenient processing. It is widely used in automobiles, home appliances and other fields. There are deficiencies in heat conduction and other aspects, and they all need to be further improved according to their application environment. Carbon fiber has the characteristics of small specific gravity, high specific strength and specific modulus, and corrosion resistance. It is the most important reinforcement of advanced composite materials. Carbon fiber reinforced composite materials have the advantages of high strength, light weight, high temperature resistance, high heat resistance, etc. It is of gre...
