METAL-RESIN COMPOSITE AND METHOD OF PREPARING THE SAME AND SHELL OF ELECTRONIC PRODUCT

The present disclosure provides a metal-resin composite and a method of preparing the same. The metal includes titanium or titanium alloy, the composite includes a metal substrate and a resin layer coated on at least a part of a surface of the metal substrate, recesses are distributed on the part of the surface of the metal substrate coated with the resin layer, a part of resin of the resin layer extends to fill in the recesses, and a concentration of an oxygen element on the surface of the metal substrate is greater than 1 wt %. The method includes dipping a metal substrate in an etching solution containing at least one alkali metal hydroxide so as to form recesses on the surface of the metal substrate, and injecting a resin onto the surface of the after-surface-treatment metal substrate to form a resin layer. The metal-resin composite of the present disclosure is suitable for a shell of an electronic product.
