Abstract

The invention discloses a moisture-absorbing easy-to-scrub coating layer and a preparation method thereof, and belongs to the technical field of coating layer materials. The preparation method comprises the steps: stirring nano bismuth oxide subjected to hydrogen plasma treatment and 3-aminopropyltrimethoxysilane in water to prepare modified nano bismuth oxide, adding the modified nano bismuth oxide and carboxymethyl cellulose into polyethylene glycol, uniformly mixing, uniformly smearing, heating to prepare a bottom coating layer, and carrying out stirring reaction of 4,4-dihydroxydiphenylamine and 3,5-dichlorobenzoic acid in a sodium hydroxide solution to prepare a diphenylamine-benzoic acid copolymer; uniformly mixing the diphenylamine-benzoic acid copolymer and polyethylene glycol, and carrying out film scraping to prepare a surface coating layer; putting the surface coating layer into a 1,4-dichlorobutane alkaline solution to prepare a modified surface coating layer; and adhering the modified surface coating layer to the bottom coating layer, and heating, to obtain the moisture-absorbing easy-to-scrub coating layer. The moisture-absorbing easy-to-scrub coating prepared by the preparation method has excellent moisture absorption, and dirt on the surface is easy to scrub.

Description

technical field [0001] The invention relates to the technical field of coating materials, in particular to a hygroscopic and easy-to-clean coating and a preparation method thereof. Background technique [0002] With the improvement of living standards, people's requirements for quality of life are getting higher and higher. At the same time, our living environment is also changing. The El Niño phenomenon leads to global warming, the expansion of urban areas, and the large increase in residential population make the heat island effect worse. Most notably, clean air and water, humidity and other inconspicuous factors that have been taken for granted in the past are becoming more and more important in the impact on our health and need to be treated more carefully. People's attention tends to focus on the things they are chasing in front of them, and they are accustomed to what they already have, and they don't think about it until they lose it. [0003] Long-term humid weather...
