Abstract
A housing includes a plastic substrate and a layer formed on the plastic substrate. The layer contains polysiloxane and epoxy resin. The layer is very thin, but evenly forms on the surface of the plastic substrate. The layer has a high hardness and can effectively protect the plastic substrate from abrasion.
Claims7
A method for making a housing, comprising:
- forming a sol solution by mixing silane coupling agent, organic solvent, and deionized water, the mass ratio of the silane coupling agent, organic solvent, and deionized water being (8-15):(80-90):(2-5), the silane coupling agent having an end group of amino, the silane coupling agent being γ-aminopropyl triethoxysilane;
- forming a coating solution by mixing the sol solution and epoxy resin, the mass ratio of the sol solution to the epoxy resin being (75-85):(15-25);
- providing a plastic substrate;
- and
- coating the surface of the plastic substrate with the coating solution and drying the coating solution to form a layer.
