Abstract

The invention belongs to the field of a polymer material, and concretely discloses a preparation method of an aluminum silicate crystal whisker enhanced polyether-ether-ketone modified material. According to the method, silicon-containing M-phenyl polyether-ether-ketone is used as a coupling agent; the coupling agent is used for performing surface modification on aluminum silicate crystal whiskers; the modified aluminum silicate crystal whiskers and polyether-ether-ketone are processed through the processes of solution dispersion, drying, fusion extrusion blending and injection molding shaping; finally, the aluminum silicate crystal whisker enhanced polyether-ether-ketone modified material is obtained. Compared with a polyether-ether-ketone un-enhanced material, the aluminum silicate crystal whisker enhanced polyether-ether-ketone modified material has the advantages that the stretching and bending performance are greatly improved; the indexes such as the wear-resistant performance, the fireproof performance, the dimension stability and the linear expansion coefficient are greatly improved; the material cost is at least reduced to 75 to 80 percent of the original cost.
