Abstract

The invention discloses a polyether-ether-ketone modified composite material and belongs to the field of a high polymer material. The polyether-ether-ketone modified composite material comprises the following components in parts by weight: 100-120 parts of polyether-ether-ketone powder, 5-35 parts of silicon carbide powder, 5-25 parts of zirconium oxide powder and 0.1-3 parts of lubricating agent, wherein the fusing viscosity of the polyether-ether-ketone powder is at 100-650Pa.s. The invention discloses the polyether-ether-ketone modified composite material and a preparation method thereof. The polyether-ether-ketone modified composite material disclosed by the invention is modified by adding silicon carbide and zirconium oxide; the prepared polyether-ether-ketone modified composite material has the characteristics that the friction coefficient at least can be reduced by 0.06 and the tensile strength at least can be increased by 21MPa; and compared with a pure polyether-ether-ketone material, the polyether-ether-ketone modified composite material has the advantages that the service life and the use temperature are both promoted, the invalid time at least can be prolonged for 148h, the use temperature can be increased by 50 DEG C, the maximum use temperature can reach up to 310 DEG C, and the cost is reduced while the application field is widened.

Description

technical field [0001] The invention relates to the field of polymer materials, and more specifically, to a polyether ether ketone modified composite material and a manufacturing method thereof. Background technique [0002] Polyether ether ketone is a kind of fully aromatic semi-crystalline thermoplastic engineering plastics. Because the macromolecular chain contains rigid benzene rings, soft ether bonds and carboxyl groups that increase the intermolecular force, the structure is regular, so it has high heat resistance. Excellent comprehensive properties such as high strength, high modulus, high fracture toughness, etc., can be used for a long time at 250 °C. [0003] However, the material cost of pure polyetheretherketone is relatively high, the use temperature of the product is relatively low, the temperature resistance and wear resistance strength cannot meet the standard requirements of some products, and the application range is narrow.
