Abstract

The invention provides a ceramic coating with a laser marking function. The coating is composed of a primer and a topcoat, and the raw materials and the parts by weight of the raw materials are as follows: primer: 30-50 parts of nano-silica sol resin, water-based 1-4 parts of solvent, 0.2-0.8 parts of organic bentonite thickener, 20-40 parts of inorganic pigments / fillers, 10-20 parts of large particle size silica sol resin; topcoat: 55-80 parts of nano-silica sol resin, water-based solvent 25-35 parts, laser marking powder 1-5 parts, pearl powder 0-3 parts. The present invention utilizes the distinctive identification pattern technology to provide the product with good appearance and adhesion, and meets the high requirements of high-end customers for coating food safety, as well as wear resistance and non-stick performance.

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...
