Abstract

The invention discloses an anti-sticking coating and a preparation method thereof. The anti-sticking coating comprises a component A and a component B, wherein the component A comprises the following components in parts by weight: 18-35 parts of hydroxy acrylic acid dispersion, 10-20 parts of urethane acrylate, 3-15 parts of water-based fluorocarbon resin emulsion, 5-10 parts of chitosan, 1-5 parts of nanoscale titanium dioxide, 6-20 parts of quartz powder, 5-13 parts of calcium carbonate, 2-10 parts of mica powder, 0.1-0.6 part of dispersing agent, 0.3-2 parts of leveling agent, 0.2-2 parts of diluent, 0.2-1.2 parts of a defoaming agent, and 1-5 parts of a solvent; the component B is a curing agent; wherein the weight ratio of the component A to the component B is (3-10): 1. The anti-sticking coating disclosed by the invention is high in sticking resistance, excellent in physical and chemical properties, excellent in self-cleaning capability and wide in application range; the preparation method of the anti-sticking coating is stable in reaction process, good in product stability and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-sticking 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 scribbled graffiti and random small advertisements have seriously affected the appearance of the city, and it takes a lot of manpower and material resources to remove these graffiti, thus producing anti-sticking paint. The current commercially available anti-sticking coatings have poor coating durability after use, and under the influence of the sun and rain, the anti-sticking coatings often lose their effect in a short period of time, which in turn leads to a series of problems such as repairs.
