Problems solved by technology

[0003] However, PEKK pure resin's hardness, wear resistance, strength and other performance indicators are insufficient compared to metal indicators. In traditional methods, the mineral fillers used in modification are mostly long fibers such as glass fibers and carbon fibers or chopped strands. Fiber-reinforced modification, compared with adding long-fiber materials, adding whiskers can overcome the disadvantages of continuous long fibers that are difficult to distribute evenly in complex molds, prone to poor glue areas, poor surface finish, and severe mold wear during processing. Moreover, due to the addition of whiskers, the moisture and heat resistance of the composite material is significantly improved, and the mechanical properties and strength retention of the material can also be significantly improved.

[0045] Since the grades of the selected polyetherketoneketone resin base materials are CC6651-1 and CC5601-1, the relevant processing temperatures are respectively 25°C and 40°C lower than those in Examples 1 to 3. In addition, according to the above-mentioned Example 1 ~3 The same method, after the integrated pulverization and mixing treatment, then hot press molding. The strength, wear resistance and hardness of each sample were measured, and the results are shown in Table 1.

Abstract

The invention belongs to the technical field of composites and in particular relates to a whisker reinforced poly(ether ketone ketone) composite and a preparation method thereof. The whisker reinforced poly(ether ketone ketone) composite is prepared from the following raw materials in parts by weight: 100 parts of poly(ether ketone ketone) resin, 5-30 parts of fusible fluoroplastic, 10-50 parts ofinorganic whiskers, 0.1-5 parts of a coupling agent and 0.1-3 parts of a crosslinking agent. The obtained poly(ether ketone ketone) composite maintains inherent excellent high temperature resistance,fire resistance, chemical resistance and moist heat resistance of poly(ether ketone ketone) resin, and shear strength and impact strength of a workpiece also can be greatly improved, so that wear resistance of the workpiece can be more excellent; and meanwhile, material cost also can be greatly reduced, and more extensive application requirements are met.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a whisker-reinforced polyetherketoneketone composite material and a preparation method thereof. Background technique [0002] Polyether ketone ketone (hereinafter also referred to as "PEKK") resin is a semi-crystalline, high temperature resistant thermoplastic resin with excellent mechanical properties, chemical corrosion resistance, radiation resistance and flame retardancy, etc., especially suitable for high-performance compounding Material base resin and super engineering plastics. PEKK resin is widely used in new energy vehicles, smart home equipment, modern logistics warehousing, aerospace, etc. , high-end food processing equipment, medical equipment and other industries. [0003] However, PEKK pure resin’s performance indicators such as hardness, wear resistance, and strength are insufficient compared with metal indicators. In traditional methods, ...
