Abstract

The invention discloses an anti-fouling and anti-doodling dope and a preparation method. The dope contains the following ingredients(based on weight portions): 15-20 portions of biradical fluoro-acrylate oligomer, 3-10 portions of biradical silicone acrylate oligomer, 10-40 portions of 6-radical polyurethane acrylate oligomer, 1-30 portions of biradical epoxy acrylate oligomer, 1-10 portions ofphotoinitiator, 10-25 portions of reactive diluted monomer, 0.5-5 portions of addition agent and 10-25 portions of organic solvent. Paint film made from the anti-fouling and anti-doodling dope is structurally compact, with surface tension reaching 27-33dyne / centimeter and effectively prevents various doodling materials, such as oil pen, waterborne pen, ink jet and pollutant from infiltrating to thedope or the substrate, thus reducing cleaning difficulties; meanwhile, the dope is good in dirt resistance and doodling resistance and long in service life. The dope can be prepared by mixing the ing redients of the dope to be even, so the preparation method is economic and simple.

Description

technical field [0001] The invention relates to a functional coating and a preparation method thereof, in particular to a coating with antifouling and anti-graffiti functions and a preparation method thereof. Background technique [0002] Graffiti and pollution exist all the time in modern life, such as graffiti on telephone booths, telephone poles, wall curtain panels, building exterior walls, etc. Dirt on boards, kitchen cabinet boards, and kitchen utensils (gas stoves, hoods, etc.) has increasingly become an annoyance in people's daily life. Due to the porosity of the substrate, graffiti and dirt easily penetrate into the substrate and are difficult to clean , has become a problem that people urgently need to solve. [0003] In the prior art, the paint film formed after the traditional paint is cured has problems such as insufficient hardness, poor temperature resistance, and easy cracking. When it is polluted by graffiti or dirt, it cannot achieve the effect of antifoul...
