Problems solved by technology

Although the above-mentioned anti-graffiti and anti-adhesive coatings have significantly improved the anti-graffiti effect and anti-aging performance of the paint film during application, after repeated graffiti and physical wear, the surface energy will increase and the anti-sticking performance will decrease.

preparation example Construction

[0041] The preparation method of the A component comprises the following steps:

[0042] Add the modified hydroxy acrylic resin and FEVE low surface energy fluororesin into the mixing tank, stir with the agitator at a speed of 600-700 rpm, then add polyorganosiloxane, and continue stirring at 800-850 rpm for at least 10 Minutes, then add solvent, functional additives and silicone modified acrylate, continue to stir at 500-600 rpm for at least 10 minutes, adjust the viscosity with the remaining part of the solvent, filter and pack after passing the inspection;

[0043] The preparation method of the B component comprises the following steps:

[0044] First add the solvent into the mixing tank, then add the curing agent, stir at 500-600 rpm under an inert atmosphere, and then filter and pack.

[0045] When using, fully mix A and B components according to a certain weight ratio and stir evenly, adjust to a suitable viscosity and then apply to obtain a cured paint film.

Abstract

The invention relates to the field of coatings, in particular to an anti-doodling, anti-fouling, anti-sticking and high weather-resistant coating and a preparation method thereof. The anti-doodling, anti-fouling, anti-sticking and high weather-resistant coating comprises an A component and a B component, wherein the A component comprises the following components in parts by weight: 20-50 parts of modified hydroxy acrylic resin, 10-40 parts of FEVE fluorocarbon resin, 1-5 parts of organopolysiloxane and 2-10 parts of organosilicone modified acrylate; and the B component comprises the following components in parts by weight: 70-80 parts of curing agent and 20-30 parts of solvent. The anti-doodling, anti-fouling, anti-sticking and high weather-resistant coating has very excellent hydrophobic and oleophobic properties and anti-doodling and anti-sticking functions, reduces water percolation, and can prolong the service life of a paint film; and mould growth is not easy.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an anti-graffiti, anti-fouling, anti-sticking and high weather resistance coating and a preparation method thereof. Background technique [0002] With the development of modern industrial economy, in urban life, whether it is public transportation, such as subways, trains, light rail, buses, or public facilities, such as bus stop signs, bus shelters, telephone poles, and walls, it can be seen everywhere All kinds of graffiti and random small advertisements have seriously affected the appearance of the city, and it will take a lot of manpower and material resources to remove these graffiti. Through the research, it is found that the surface with low surface energy can effectively prevent graffiti adhesion and pollution. The use of high-performance anti-graffiti paint is a direct and effective means to deal with graffiti, especially the long-lasting anti-graffiti paint, whose surface is har...
