Problems solved by technology

This method has a short service life. Generally, enterprises with continuous production will spray more than 2 times a month, so that the whole workshop will have an unpleasant smell, making workers unable to work, or working in a harsh environment. Now there are many common The use of anti-static sheets such as PP, ABS, PE, PC, etc., but ordinary anti-static materials cannot meet the high temperature of 200 ° C in the electronics manufacturing industry, especially the current equipment and tooling in the electronics manufacturing industry, not only require anti-static, but also Requires high temperature resistance
Such ordinary anti-static materials cannot be satisfied, and a new type of material is needed, which has the characteristics of high temperature resistance, high purity, wear resistance, chemical stability, etc.

Abstract

The invention relates to an antistatic polyether-ether-ketone composite material and a preparation method thereof, and belongs to the fields of high polymer materials and the preparation thereof. The composite material of the invention is prepared by selecting polyether-ether-ketone, PAN carbon fiber, acetylene carbon black, and a coupling agent as raw materials, and the composite material is molded by adopting the method of compression molding. According to the invention, the preparation method is simple, the parameters are easy to control, the consistency is good, the stability is high, and no special device is needed. The composite material can be applied to vacuum suction cups and wafer trays used in semiconductor manufacturing industry, electronic components used in hostile environments such as high temperature and high pressure in oil field industry, and sealing-connecting electronic components used in electronic and electrical industries, and the like.

Description

technical field [0001] The invention belongs to the field of polymer materials and their preparation, and in particular relates to a composite material with polyether ether ketone as a main raw material and a preparation method thereof. Background technique [0002] PEEK has many excellent properties such as high temperature resistance, abrasion resistance, chemical corrosion resistance, hydrolysis resistance, insulation, excellent strength and toughness, stability, fire resistance and non-toxic properties. [0003] The semiconductor manufacturing industry has high requirements on the antistatic properties of materials. Static electricity is prone to be generated during the packaging and transportation of electronic products. If the static electricity is not guided away, it will cause great harm to electronic products. At present, antistatic methods are mostly realized by spraying antistatic agents on some workpieces. This method has a short service life. Generally, contin...
