Abstract

The invention discloses a toughness-enhanced carbon fiber reinforced polyformaldehyde composite material and a preparation method thereof. The composite material is characterized by being prepared from the following raw materials in parts by weight: 90-100 parts of polyformaldehyde, 10-30 parts of carbon fibers, 4-7 parts of light calcium carbonate, 2-4 parts of copolyamide, 0.4-0.5 part of fatty acid zinc, 0.3-0.5 part of an antioxidant 1010, 3-5 parts of thermoplastic elastomer G155D, 0.3-0.6 part of a silane coupling agent KH-550, 2-4 parts of oxidized graphene and 2-3 parts of nano silica. According to the invention, the added carbon fibers are dispersed evenly in polyformaldehyde after being preheated, so that the comprehensive properties of the material can be improved; the added thermoplastic elastomer is capable of increasing the elasticity of the polyformaldehyde and improving the fracture property; the added light calcium carbonate is capable of improving the toughness of the polyformaldehyde; as a result, the product competitiveness is greatly improved.

Description

technical field [0001] The invention relates to a toughness-enhanced carbon fiber-reinforced polyoxymethylene composite material and a preparation method thereof, belonging to the technical field of plastic production. Background technique [0002] As one of engineering plastics, polyoxymethylene is a high-density, highly crystalline linear polymer with high strength and modulus, good wear resistance, chemical corrosion resistance, creep resistance, fatigue resistance, and products Good dimensional stability and other characteristics, it is an ideal material to replace copper, zinc, aluminum and alloy products, and is widely used in automobile manufacturing, electrical and electronic, machinery, chemical and other fields. Most of the existing polyoxymethylene products in my country are general-purpose. In order to improve the use of products in the aerospace field, it must be transferred to high-end modified polyoxymethylene. Generally, it is modified in the form of composi...
