Problems solved by technology

[0003] But at present, because this material is mostly used in military industry, the modification technology of polyether ether ketone in China is very limited, and the start is very fast, and there are still many imperfections. Basically, there is no feasible and easy-to-operate method. Modification technology
Due to its molecular structure, the PEEK material itself has an ultra-high temperature resistance grade and a high molecular weight, but due to its high temperature resistance, its fluidity is poor, making processing more difficult, and the processing temperature is very high, generally at 360- Between 400 degrees

Abstract

The invention discloses a modification-enhanced polyether ether ketone material and a preparation method thereof. The modification-enhanced polyether ether ketone material is prepared from the following components in parts by weight: 50-60 parts of polyether ether ketone, 8-15 parts of polyphenylene sulfide, 30-35 parts of filling enhancer, 0.2-0.6 part of antioxidant, 0.2-0.8 part of lubricant and 0.3-0.6 part of nucleating agent. The invention has the characteristics that: the defect of poor fluidity of polyether ether ketone is overcome by adding polyphenylene sulfide, and the processing temperature and difficulty of the polyether ether ketone are greatly reduced; because the polyether ether ketone is expensive, the production cost is greatly lowered by introducing polyphenylene sulfide; and the preparation process disclosed by the invention is simple, low in cost and high in benefit and can obtain good economic benefit.

Description

[technical field] [0001] The invention relates to the field of polymer materials, in particular to a modified and reinforced polyether ether ketone material and a preparation method thereof. [Background technique] [0002] Polyetheretherketone (PEEK) is a new type of ultra-high temperature-resistant and high-performance polyetheretherketone material successfully developed and mass-produced by Victrex Company of the United Kingdom. The trade name is VICTREX. It has the advantages of high heat resistance, high strength and excellent electrical performance. Polyetheretherketone (PEEK for short) is a new type of polyether ether ketone (PEEK) which is produced by the condensation reaction of 4,4'-difluorobenzophenone and hydroquinone in the presence of alkali metal carbonate, using diphenyl sulfone as a solvent. Semi-crystalline aromatic engineering thermoplastics. It is a high-temperature resistant thermoplastic with a high glass transition temperature (143°C) and melting poin...
