Micromolecular water dispersible water-based anti-graffiti coating and preparation process thereof

Abstract

The invention discloses a micromolecular water dispersible water-based anti-graffiti coating and a preparation process thereof. The water-based anti-graffiti coating includes the following raw materials by mass: 50-70% of water-based fluorine-containing acrylic emulsion, 0.3-0.6% of dispersant, 0.3-0.8% of wetting leveling agent, 10-20% of pigment filler, 0-8% of color paste, 0.2-0.6% of antifoaming agent, 0.1-0.2% of pH regulator, 0.4-0.8% of thickener and the balance micromolecular water. The micromolecular technology is adopted to prepare the micromolecular water-based anti-graffiti coating, the transportation and using safety of the water-based coating in the cold winter in the north is greatly improved, and the surface effect is more smooth and saturated. In addition, the synergisticaction of the water-based fluorine-containing acrylic emulsion and a fluorine auxiliary agent is utilized, and the prepared micromolecular water-based anti-graffiti coating has the advantages of water-based environmental protection, good drying performance, difficulty in sagging, good frost resistance and good anti-graffiti performance.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and relates to a water-based anti-graffiti paint and a preparation process thereof, in particular to a micro-molecular water-dispersed water-based anti-graffiti paint and a preparation process thereof. Background technique [0002] It is not uncommon to see graffiti on the walls of tourist attractions. In addition, various small commercial advertisements are posted everywhere, which hinders the perception of the city and affects the appearance of the city. The most direct way to solve the problem is to apply anti-graffiti paint. In recent years, the oil-to-water wave has swept almost all industrial paint fields, and water-based anti-graffiti coatings have already entered the market. Like other types of water-based industrial paints, in the cold winter in the north, general water-based anti-graffiti coatings use ordinary As a solvent, water is easy to freeze and damage, and when used out...

AI Technical Summary

Problems solved by technology

Although this water-based anti-graffiti coating is water-based and environmentally friendly, with low VOC content, it is easy to wear due to surface migration, so that the aging effect is not long, and it uses anatase titanium dioxide, which is not suitable for long-term outdoor weather resistance requirements.
