Abstract

The invention relates to the field of materials, in particular to a high strength and wear resistant aromatic composite material, a preparation method and application thereof. The composite material includes: 65-85 parts of an aromatic polymer, 5-20 parts of ceramic filler and 10-30 parts of fiber. According to the invention, polyether ketone, polyether sulfone, polyether ether ketone and other aromatic polymers are adopted as the matrix resin to effectively improve the mechanical properties, thermal stability, corrosion resistance and the like of the product. The adding of the ceramic fillerinto the aromatic polymer matrix not only can improve the thermal conductivity coefficient of the product, but also can improve the product strength, and endows the product with the advantages of wearresistance, high hardness, flame retardance, aging resistance, environmental protection, etc. The high strength and wear resistant aromatic composite material provided by the invention has the characteristics of convenient shaping, simplicity and high efficiency, can achieve one-time shaping, and also can be used for secondary processing. The product has high degree of design freedom, is suitablefor large-scale production, and well solves the problems of low strength, poor hardness, no flame retardance, signal shielding and the like of the shells and shell components in existing electronic products, wearable equipment or household appliances.

Description

technical field [0001] The invention relates to the field of materials, in particular to the preparation of high-strength and wear-resistant aromatic composite materials. Background technique [0002] With the development of the manufacturing process of electronic products, more requirements are put forward for the materials for manufacturing electronic product casings. At present, the materials for making electronic product casings are required to have high strength, good dimensional stability, good appearance, good texture, high hardness, Wear-resistant, anti-aging, smooth signal transmission and other characteristics. In the prior art, metal, plastic or glass are generally selected as the housing material of electronic products. The electronic product shell made of metal material has the advantages of good texture and high strength, but it has defects such as high cost, difficult processing, and signal shielding, and it is not easy to color in the subsequent processing p...
