Problems solved by technology

[0002] Due to the high surface energy of the hydrophilic surface, the hydrophilic coating is easily polluted by pollutants, which affects the continuous effectiveness of the hydrophilic property. At present, the main means to solve the above problems is to prepare environment-responsive polymers, but this kind of technical route It is usually necessary to prepare complex polymers or have high requirements for the treatment of substrates, making it difficult to apply on a large scale in industry

Abstract

The invention discloses a method for preparing a stain-proof hydrophilic coating from self-crosslinking hydrophilic particles. The method comprises the following steps of: copolymerizing N-methylol acrylamide (N-MAM), methoxypolyethylene glycol monomethyl acrylate (MPEG-MA) and acrylic acid (AA) to form hydrophilic crosslinking particles by 'self-crosslinking', compounding the hydrophilic crosslinking particles and water-soluble acrylic resin solution, and successfully preparing the stain-proof hydrophilic coating with aids of water and auxiliary agent. The stain-proof hydrophilic coating is particularly suitable to be used as an air-conditioning hydrophilic aluminum foil coating.

Description

technical field [0001] The invention relates to hydrophilic coatings, in particular to a method for preparing antifouling hydrophilic coatings from self-crosslinking hydrophilic particles. Background technique [0002] Due to the high surface energy of the hydrophilic surface, the hydrophilic coating is easily polluted by pollutants, which affects the continuous effectiveness of the hydrophilic property. At present, the main means to solve the above problems is to prepare environment-responsive polymers, but this kind of technical route Usually, it is necessary to prepare complex polymers or have high requirements on the treatment of substrates, making it difficult to apply on a large scale in industry. If a kind of anti-fouling hydrophilic coating can be prepared by a simple and easy method, the popularization and application of hydrophilic coating will be taken a big step forward. Contents of the invention [0003] The purpose of the present invention is to provide a me...
