High-wear-resistance ceramic material as well as preparation method and application thereof

ZENG LIXIA

The invention belongs to the technical field of ceramic materials, and discloses a high-wear-resistance ceramic material and a preparation method and application thereof.The preparation method comprises the steps that fly ash is pretreated to remove heavy metal elements, then the fly ash and modified nano-zinc oxide are subjected to ball milling till the particle size is 20 micrometers or below, ceramic powder and an adhesive are added and mixed to be uniform, heat treatment is conducted after compression molding, and the high-wear-resistance ceramic material is obtained; obtaining a porous ceramic material precursor; soaking the porous ceramic material precursor in an alcoholic solution, and grafting a modifier on the surface of the porous ceramic material precursor under the action of a silane coupling agent to obtain a porous ceramic material; heating polyvinyl chloride resin to be soft, adding a curing agent, and uniformly mixing to obtain immersion liquid; and immersing the porous ceramic material into the immersion liquid to enable the porous ceramic material to be immersed into pores of the porous ceramic material, and naturally cooling to obtain the high-wear-resistance ceramic material. According to the preparation method, the preparation raw materials are easy to obtain and low in cost, operation is easy, safety is high, and the prepared ceramic material is good in wear resistance.
