Abstract

The invention belongs to the field of ceramic tile surface anti-fouling easy-cleaning materials, and particularly discloses an anti-fouling nanometer easy-cleaning liquid and a preparation method thereof, and an anti-fouling nanometer easy-cleaning ceramic preparation method, the anti-fouling nanometer easy-cleaning liquid comprises, by weight, 40-80 parts of micromolecule organosiloxane, 10-40 parts of hydroxyl silicone oil, 5-40 parts of ethanol silica sol, 0.1-5 parts of a catalyst, 5-30 parts of isocyanate silane, and 10-40 parts of a mercapto silane coupling agent. The invention further discloses a preparation method of the organic silicon nano easy-cleaning liquid and a method for preparing anti-fouling nano easy-cleaning ceramic from the organic silicon nano easy-cleaning liquid. The anti-fouling nano easy-to-clean liquid is simple in preparation process, safe, non-toxic, green, environment-friendly, durable and efficient in anti-fouling and easy-to-clean effect and long in service life, and caters to the pursuit of people for clean and comfortable living space.

Description

technical field [0001] The invention belongs to the field of anti-fouling and easy-cleaning materials for ceramic tile surfaces, in particular to an anti-pollution nanometer easy-cleaning liquid and a preparation method thereof, and a preparation method of an anti-fouling nanometer easy-cleaning ceramic. Background technique [0002] In daily life, many consumers are troubled by the difficulty of removing dirt on tiles. This is the same as accidentally staining a piece of oil on brightly colored clothes. are very concerned. In terms of anti-fouling performance, the national standard only divides glazed tiles into 5 levels, but there is no clear requirement for unglazed tiles. Although the water absorption rate of qualified porcelain polished tiles on the market is relatively close, the antifouling ability is quite different. The antifouling ability of the product is not only related to the closed porosity, but also related to other properties of the polished tiles, such as ...
