Water-based anti-doodling coating

Abstract

A water-based anti-doodling coating belongs to the field of coating chemical industry and is a double-component coating composed of a component A and a component B. The component A comprises the following components in parts by weight: 5-10 parts of water-based hydroxyl polyacrylate dispersion, 40-55 parts of organosiloxane modified water-based hydroxyl polyacrylate resin, 15-20 parts of pigment, 1.5-2.0 parts of gas silicon, 0.05-0.15 part of wetting agent, 1.0-3.0 parts of coalescing agent, 0.1-0.3 part of defoaming agent. 0.5 to 1.0 part of a leveling agent, 1.0 to 1.5 parts of an anti-aging agent, 0.5 to 1.5 parts of a dispersant, 15.0 to 17.0 parts of deionized water, 0.5 to 2.0 parts of a coupling agent and 2.0 to 5.0 parts of a surfactant; and the component B comprises the following components in parts by weight: 60-80 parts of a hydrophilic modified aliphatic polyisocyanate curing agent and 40-20 parts of a solvent. The water-based anti-doodling coating provided by the invention is high in water resistance, smooth, stain-resistant and anti-doodling, and provides excellent touch feeling.

Description

technical field [0001] The invention belongs to the field of paint chemical industry, in particular to a water-based anti-graffiti paint and a preparation method thereof. Background technique [0002] With the development of the country's economy, people's living standards and quality have been greatly improved. However, small advertisements are pasted everywhere on public facilities such as poles, light poles, aluminum-plastic panels, stop signs, bus booths, billboards, etc. on both sides of roads in urban areas and communities, which not only affects the appearance of the city, but also costs a lot of money and material resources to remove every year. , the government and the public hate it, and it has also brought great trouble to the advertising business. At present, the oily and easy-to-clean paints on the market are difficult to clean the stains of marker pens and oil-based pens, and the paint film is easily damaged during cleaning. At present, some manufacturers at ...

AI Technical Summary

Problems solved by technology

[0009] In order to solve the problems of the existing oily fluorine-containing low surface energy anti-graffiti coatings with insufficient long-term effectiveness and environmental protection, the present invention develops a water-based anti-graffiti coating. The coating uses less solvent, less VOC volatilization, and has good weather resistance Excellent, can be applied to the surface protection of steel structures in public places such as bus stop signs, sidewalks, overpasses, etc., especially to prevent graffiti and stains, making it easy to remove marker pen ink, juice, chewing gum, stickers, etc.
