Abstract

The invention provides a ceramic coating with a laser marking function. The ceramic coating comprises primer and finish, wherein the primer is prepared from the following raw materials in parts by weight: 30-50 parts of nano-silica sol resin, 1-4 parts of an aqueous solvent, 0.2-0.8 parts of an organic bentonite thickener, 20-40 parts of inorganic pigment / filler and 10-20 parts of large-particle-size silica sol resin; the finish is prepared from the following raw materials in parts by weight: 55-80 parts of nano-silica sol resin, 25-35 parts of an aqueous solvent, 1-5 parts of laser marking powder and 0-3 parts of pearl powder. Good appearance and adhesive force are provided for products with a characteristic identification pattern technology, the safety requirement of high-end customers for coating food is met, and high requirements for wear resistance, non-stick performance and the like are met.

Description

technical field [0001] The invention relates to the technical field of ceramic coatings, in particular to a ceramic coating with a laser marking function and a preparation method thereof. Background technique [0002] At present, there are two main types of non-stick coatings commonly used in the market. One is fluorine coatings based on polytetrafluoroethylene (PTFE), such as Teflon; Ceramic coatings prepared by sol-gel method. Fluorine coatings based on PTFE have good long-term non-stick properties, but because the PTFE film is too soft, the scratch resistance and hot hardness at high temperatures are insufficient. Compared with PTFE, ceramic coatings have the advantages of being more environmentally friendly, not easy to fall off, and not easy to decompose under high temperature. It has promoted the upgrading of cookware coatings, and has a bright future development prospect. [0003] Non-stick ceramic coating is a new type of water-based inorganic coating with environ...
