Problems solved by technology

It is difficult to prepare the nano-pore structure on the surface of ceramics. Currently, the gluing technology of heterogeneous materials is widely used, but this technology has disadvantages such as overflowing glue and poor bonding, and the products formed by gluing have relatively no autonomy in structure and other related problems.

Abstract

The invention discloses a ceramic surface treatment method, a ceramic product and a ceramic plastic composite body. The method comprises the following steps of soaking ceramic to be treated into a fluoride acid solution so as to perform primary surface etching; soaking the ceramic subjected to primary surface etching into a first inorganic acid solution so as to perform secondary surface etching; further obtaining the ceramic with nanometer level holes on the surface. By using the mode, the ceramic with the nanometer hole structures can be prepared; after the plastic injection molding forming, the bonding force of the product is high; the combination is very tight.

Description

technical field [0001] The invention relates to a ceramic surface treatment method, a ceramic product and a ceramic plastic composite body. Background technique [0002] The plastic-ceramic integrated composite molding technology is to make the plastic melt enter the nano-hole structure on the ceramic surface under a certain pressure after forming nano-holes on the ceramic surface, thereby forming a microscopic mechanical interlock. It is difficult to prepare the nano-pore structure on the surface of ceramics. Currently, the gluing technology of heterogeneous materials is widely used, but this technology has disadvantages such as overflowing glue and poor bonding, and the products formed by gluing have relatively no autonomy in structure and other related problems. . Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a surface treatment method for ceramics, ceramic products and ceramic-plastic composites, which ca...
