Problems solved by technology

However, the main problems of the existing above-mentioned processing methods are that the edges and corners are not clear, the surface gloss and chroma cannot be adjusted, and the stamping process is only suitable for metal materials with toughness, and there is nothing to do for brittle materials such as ceramic materials, especially Zirconia materials as fine ceramics are more difficult

Abstract

The invention discloses a surface chemical etching method of a ceramic material product. The method comprises the steps that a ceramic material is pretreated, so that the chroma, glossiness and roughness of the surface of the ceramic material meet requirements; the surface of the pretreated ceramic material product is coated with a corrosion-resistant protective film, and soaked and etched in an acid solution; the etched ceramic material product is cleaned; the protective film is removed; and drying is performed. The method can achieve high-quality and high-efficiency surface etching on various hard ceramic materials; the etching quality is far better than the traditional technology; concave and convex are not limited; the depth is controllable; the third dimension is strong; the glossiness, roughness and chroma of the surface are controllable; various art fonts and any patterns can be etched; panels in different chroma can be etched; the operation is simple; and the generality is high. The invention further discloses the ceramic material product adopting the etching method for surface processing.

Description

technical field [0001] The invention relates to a surface chemical etching method, in particular to a method for chemical etching on the surface of ceramic material products. Background technique [0002] At present, the traditional processing methods for the surface pattern of metal materials include stamping, injection molding or CNC processing, and the surface pattern of plastic is generally formed by injection molding process. The pattern formed by injection molding is not strong, the edges and corners are not clear, and lacks aesthetic feeling; the pattern formed by metal material by stamping also has the above defects. The reason for the above is that no matter whether injection molding or stamping is used, the root of the pattern is difficult to handle , and the surface of the material treated by the above method is difficult to control the surface roughness, gloss and surface chroma, and the appearance is single in color, lacking three-dimensionality and aesthetic fe...
