Abstract

The invention discloses a preparation method of a wear-resisting polyether-ether-ketone composite material filled and reinforced by calcium carbonate crystal whisker-vermiculite. The method comprisesthe steps of drying polyether-ether-ketone in a vacuum drying oven, loading the dried polyether-ether-ketone, silane-modified nanometer titania, surface-treatment calcium carbonate crystal whisker andsurface modification treatment carbon fiber, and organic intercalated vermiculite in a high-speed mixing machine, stirring and mixing at low speed, loading in a mold, pre-pressing, putting in a furnace, heating for melting, then placing into a press vulcanizer for mould pressing, air cooling, taking out, and annealing to obtain the composite material. Hexadecyl trimethyl ammonium bromide is adopted for carrying out organic intercalation treatment on lamellar vermiculite, so that the interlayer spacing of the vermiculite is increased; the vermiculite and the nanometer titania are compounded tomodify the polyether-ether-ketone, so that the oxidation of the polyether-ether-ketone is delayed, and the thermal and oxidative aging resistance of the polyether-ether-ketone is improved; the nanometer titania has a higher ultraviolet light shielding effect, so that the light aging resistance of the polyether-ether-ketone is improved.

Description

technical field [0001] The invention belongs to the field of mechanical parts materials, and in particular relates to a preparation method of calcium carbonate whisker-vermiculite filled and reinforced wear-resistant polyetheretherketone composite material. Background technique [0002] In industrial production or life, anti-friction and wear-resistant materials are indispensable. With the improvement of use requirements, resin [0003] Base wear-resistant materials are booming due to their unique advantages (light weight, self-lubricating, easy processing, etc.). Polyetheretherketone [0004] Resin has high mechanical strength, excellent chemical stability, wear resistance and easy processing. As a typical thermoplastic high-performance resin, it has been widely used in military and civilian fields. As a very good wear-resistant polymer material, polyetheretherketone can maintain good wear resistance under certain load, sliding speed and temperature range. However, on th...
