Problems solved by technology

[0003] After being used for a period of time, the polished tiles currently on the market will be affected by external stress, and the surface will form uneven structures again, which will lead to poor antifouling effect, reduced gloss, and unsustainable antifouling effect; Under high temperature and low temperature conditions, the polishing liquid on the surface is easy to fall off, resulting in an unsustainable antifouling effect; in addition, the current commercially available polishing liquid has relatively harsh storage conditions, and it is prone to deterioration phenomena such as agglomeration and condensation under high or low temperature conditions, which in turn affects its polishing effect

Abstract

The invention relates to the field of ceramic materials, in particular to a ceramic polishing liquid with a core-shell structure. A ceramic polishing liquid with a core-shell structure. According to parts by weight, the raw materials of the polishing liquid include 30-50 parts of functional hybrid nanoparticles, 3-7 parts of water-based silicone glass resin, 5-18 parts of silica sol, 0.5 to 1.2 parts of emulsifier, 0.1 to 5 parts of additives, and 30 to 70 parts of water; the functional hybrid nanoparticle body is prepared by the specific method of the present invention, and the functional hybrid particle body is added to the polishing liquid to make The ceramic surface coated with polishing liquid maintains good flatness during use, and the polishing liquid will not fall off under high temperature and low temperature conditions, and the antifouling effect is durable; in addition, the invention improves the polishing effect by adding a specific emulsifier. Liquid stability at high and low temperatures.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a ceramic polishing liquid with a core-shell structure. Background technique [0002] Ceramic products, such as ceramic tiles, have uneven surfaces after being polished. If they are used directly, they will not only affect the appearance and touch, but also be easily contaminated with pollutants during use. Therefore, the surface of ceramic tiles is polished before leaving the factory. To meet the requirements for glossiness in practical use. [0003] After being used for a period of time, the polished tiles currently on the market will be affected by external stress, and the surface will form uneven structures again, which will lead to poor antifouling effect, reduced gloss, and unsustainable antifouling effect; Under high temperature and low temperature conditions, the polishing liquid on the surface is easy to fall off, resulting in an unsustainable antifouling effe...
