Abstract

The invention discloses oil-based anti-graffiti adhesion resistant paint and a preparation method thereof, and belongs to paint and a preparation method thereof. Components A of the paint comprise hydroxy acrylic resin, fluorocarbon resin, modified polydimethyl siloxane resin, polyacrylate modified organic silicon resin, smooth flow agent, flatting agent, antifoaming agent, drier, dibutyl tin laurate, butyl acetate and dimethyl benzene; components B comprise hexamethylene diisocyanate, butyl acetate and ethylene glycol monoethyl ether acetate; and the mixture ratio of the components A to the components B is 3:1. The invention also discloses the preparation method thereof. The paint has the advantages of good anti-graffiti adhesion resistant function, super-strong scrubbing resistance, easy cleaning, and quick and convenient construction, has limited harmful substances, and achieves national requirement.

Description

technical field [0001] The invention belongs to coatings and a preparation method thereof, and relates to an oily anti-graffiti and anti-sticking coating and a preparation method thereof. Background technique [0002] All kinds of small and wild advertisements pasted and graffiti in cities have always been regarded as "urban psoriasis" and have become a chronic disease that is difficult to cure in cities across the country, interfering with the economic order of cities. Thereby just produce anti-graffiti anti-adhesion coating, the anti-graffiti anti-adhesion coating currently available in the market is mainly to be film former with acrylic resin, is equipped with various additives processing. UV resistance is poor, weather resistance is also poor, water resistance, acid and alkali resistance, solvent resistance are poor, and the hardness of the paint film is not ideal. Poor anti-sticking property. Contents of the invention [0003] The purpose of the present invention is...
