Problems solved by technology

At present, the inkjet printing ceramic inks that have been published for decorative ceramics have been disclosed to have photocatalytic properties, but their photocatalytic properties still need to be improved; in addition, the colorants of ceramic inks are mainly organic solvent-soluble Composed of metal salts, after the ceramic ink is printed and baked, some colorants undergo chemical changes under high temperature, which leads to darkening or even no coloring of the colorants, especially red and yellow

Description

【Technical field】 [0001] The invention belongs to the technical field of preparation of photocatalyst materials, and in particular relates to a preparation method of a modified molecular sieve specially used for ceramic ink. 【Background technique】 [0002] With the development of science and technology and the modernization of industry, people's living standards have been significantly improved, but at the same time, people have also been harmed by the accompanying environmental pollution. Pollution such as water pollution, air pollution and indoor harmful gases have caused serious harm to human health. Sewage treatment and air purification have therefore become important research contents for scientific researchers in various countries. How to effectively remove toxic substances such as surfactants, dyes, and heavy metal ions in industrial wastewater, as well as organic waste gas and toxic gases in the atmosphere, has become a hot topic in various research fields. As an a...
