Abstract

The invention discloses anti-doodling fluorescent water paint for an interior wall and a preparation method of the water paint. The anti-doodling fluorescent water paint for the interior wall is prepared from components as follows: finished paint and a curing agent, wherein the finished paint comprises modified acrylic resin, an antibacterial agent, a mildew preventive, a wetting agent, a dispersant, a defoaming agent, deionized water, titanium dioxide, a thickener, a levelling agent, a pH regulator, a coalescing agent and fluorescent powder; the curing agent comprises modified aliphatic polyisocyanate and an organic solvent. The modified acrylic resin and modified aliphatic polyisocyanate are crosslinked in a specific proportion for film formation; by means of hydroxyl functional groups contained in modified acrylic resin, coating film surfaces are arranged in an oriented manner and crosslinked with surface functional groups of polymer structures in a coating, so that the water paintfor the interior wall has the characteristics of being anti-doodling, good in stain resistance, excellent in mildew-proof and antibacterial property, high in fluorescent sense, not prone to fading andenvironmentally friendly.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a fluorescent anti-graffiti interior wall coating and a preparation method thereof. Background technique [0002] At present, water-based paint for interior walls has been relatively stable and mature in terms of conventional performance and environmental protection. With the improvement of people's living standards, the technical requirements of this industry are getting higher and higher. Conventional interior wall paints can no longer meet people's requirements. The functional aspects of coatings are developed. [0003] Although there are many studies on anti-graffiti water paint, there are few studies on the application of fluorescent anti-graffiti water paint to home decoration. In recent years, with the refinement of the market, more and more users are interested in indoor wall surface There are special requirements for paint, which generally require good environmental performance....
