Technical Field

[0001] The invention relates to the technical field of ceramic products, in particular to a ceramic product and a flocking process for its outer surface. Background Art

[0002] Ceramics is a product made of inorganic non-metallic materials, usually made from natural minerals such as clay, porcelain stone, and pottery clay, through a process of batching, molding, drying, and roasting. It has high temperature stability, corrosion resistance, and good insulation properties. Ceramic products range from simple daily necessities such as bowls and pots to exquisite works of art, as well as decorative and practical items used in the fields of architecture, home furnishing, and crafts. Ceramic products are a kind of industrial products widely used in modern life. For example, cups, plates, bowls for daily dining, wall tiles, floor tiles for construction, etc. Although these products have certain anti-slip and heat-proof functions. However, in actual use, especially when the objects are loaded with high-temperature materials or in very cold seasons, people will still feel hot, slippery or frozen hands (feet). It is easy to generate noise when placed. If flocking can be performed on the surface of ceramic products, it can not only increase the technical added value of ceramic products, but also overcome the above-mentioned shortcomings of existing ceramic products.
