Ceramic resin composite housing, preparation method thereof, and terminal

A preparation method of a ceramic resin composite housing, comprising:

• preparing a ceramic member with a preset shape by using organic fibers comprising between 0.1 and 5 percentage by weight as a pore-forming agent, wherein a surface that is of the ceramic member and on which injection molding is pre-performed comprises a plurality of long-strip-shaped holes that extend from the surface to the inside of the ceramic member, the long-strip-shaped holes are formed through loss on ignition of the organic fibers, the long-strip-shaped holes have an open hole structure, pore sizes of the long-strip-shaped holes range from 700 nm to 500 μm, and lengths of at least some of the long-strip-shaped holes are greater than 100 μm and less than or equal to 1000 μm;
• performing impregnation on the ceramic member by using an aqueous solution that comprises a nitrogen compound to enable the aqueous solution that comprises the nitrogen compound to enter the long-strip-shaped holes, and then performing drying to attach a layer of the nitrogen compound to inner walls of the long-strip-shaped holes;
• and
• performing injection molding on the dried ceramic member, enabling a resin liquid to enter the long-strip-shaped holes to have an exothermic reaction with the nitrogen compound, and performing fine structure processing on a resin part after the injection molding is completed, to obtain a ceramic resin composite housing.
