Description
Technical field
The present invention relates to the tetrafluoroethylene field, relate in particular to a kind of component of polyether-ether-ketone modified Teflon sheet material.
Background technology
Tetrafluoroethylene (Polytetrafluoroethene is abbreviated as PTFE) generally is called " non-sticky metallic coating " or " easy clean pot material ", is a kind of synthetic macromolecular material that has used fluorine to replace all hydrogen atoms in polyethylene.This material has the characteristics of antiacid alkali resistant, anti-various organic solvents, is dissolved in hardly all solvents.Simultaneously, tetrafluoroethylene has resistant to elevated temperatures characteristics, and its frictional coefficient is extremely low, so after can making lubrication, also become the desirable coating of easy clean pot and water pipe internal layer.But there is anti-wriggling property poor (cold flow properties) in polytetrafluoroethylene (PTFE), is difficult for processing, and there are the defectives such as space in the low molecule of hardness.In order to keep fully the good characteristic of PTFE, improve its intrinsic defective, generally by adding organism or inorganics, it is carried out improved treatment, reach the purpose of optimizing its performance.
polyether-ether-ketone (polyetheretherketone, be abbreviated as PEEK) resin is a kind of special engineering plastics of excellent performance, compare with other special engineering plastics and have many significant advantages, high temperature resistant, mechanical property is excellent, self lubricity is good, the chemicals-resistant corrosion, fire-retardant, anti-separability, polyether-ether-ketone (PEEK) resin is desirable electrical insulator, at high temperature, under the abominable working conditions such as high pressure and high humidity, still can keep good electrical insulation capability, therefore electronic information field becomes the second largest Application Areas of polyether-ether-ketone (PEEK) resin gradually, make the pipeline of carrying ultrapure water, valve and pump, in semi-conductor industry, be commonly used to make the wafer carrying device, electronic isolation diaphragm and various connecting device.As a kind of hemicrystalline engineering plastics, PEEK is insoluble to the outer nearly all solvent of the vitriol oil, thereby is commonly used to make compressor valve plate, piston ring, sealing member and various chemical pump body, valve part.
In view of this, how designing a kind of component of polyether-ether-ketone modified Teflon sheet material, with when guaranteeing that tetrafluoroethylene sheet material possesses better high thermal resistance, erosion resistance, also have better creep resistance, is the problem that the insider needs solution badly.
