Abstract

The invention discloses a method for preparing polyetheretherketone-diatomaceous earth composite materials, and belongs to the technical field of high-polymer materials. The method includes mixing alloy powder with a low melting point, crystal whiskers, starch, glycerin and water with one another, carrying out ball milling on the alloy powder, the crystal whiskers, the starch, the glycerin and thewater and carrying out sieving to obtain mixed slurry; stirring and mixing diatomaceous earth and acid with each other, and carrying out filtering, washing and drying to obtain primarily treated diatomaceous earth; mixing and stirring the primarily treated diatomaceous earth and dopamine solution with each other and carrying out filtering and drying to obtain secondarily treated diatomaceous earth; mixing the secondarily treated diatomaceous earth and the mixed slurry with each other, carrying out ball milling on the secondarily treated diatomaceous earth and the mixed slurry and carrying outreduced-pressure concentration and drying to obtain modified diatomaceous earth; carrying out banburying on polyetheretherketone powder at first, then adding the modified diatomaceous earth, plasticizers and vulcanizing agents into the polyetheretherketone powder, mixing the modified diatomaceous earth, the plasticizers, the vulcanizing agents and the polyetheretherketone powder with one anotherand carrying out extrusion molding to obtain the polyetheretherketone-diatomaceous earth composite materials. The method has the advantage that the polyetheretherketone-diatomaceous earth composite materials prepared by the aid of the method are excellent in mechanical property.

Description

technical field [0001] The invention discloses a preparation method of a polyether ether ketone-diatomite composite material, belonging to the technical field of polymer materials. Background technique [0002] Diatomaceous earth is a biogenic siliceous sedimentary rock, mainly composed of the remains of ancient diatoms, and its chemical composition is SiO 2 Mainly, available SiO 2 •nH 2 O said that its mineral composition is opal and its variants, and sedimentary diatomaceous earth sometimes contains sediments such as clay and fine sand, and sometimes only sedimentary diatom shells. Diatomite has the characteristics of large porosity, strong adsorption, stable chemical properties, light weight, high melting point, heat insulation, low refractive index, good wear resistance and electrical insulation, so it is widely used in light industry, chemical industry and Building materials and other aspects of daily life. The structure of diatomaceous earth has disc shape, needle ...
