Description

technical field [0001] The application belongs to the field of coatings, and in particular relates to an acrylic resin powder coating for ceramics. Background technique [0002] China's ceramic industry has developed rapidly, and now it has become a veritable ceramic producer and consumer in the world. The output of daily-use ceramics produced in China accounts for about 70% of the world's output, the output of display art ceramics is 65% of the world's, and the output of architectural ceramics also accounts for half of the world's total output. The ceramic industry occupies a pivotal position in the world building materials industry. Ceramic coating is a kind of novel ceramic coating that can make organic matter and inorganic matter react, so that it has the advantages of both. The hardness of the new generation of ceramic coatings can reach more than 6H. High temperature resistance of 400 degrees, non-stick effect, various colors. And can be made into xylene ceramic co...
