Abstract

The invention discloses aqueous anti-graffiti adhesion resistant paint and a preparation method thereof, and belongs to paint and a preparation method thereof. The paint consists of the following components by weight portion: 50 to 55 portions of emulsion, 2 to 4 portions of organic silicon emulsion, 14 to 16 portions of siloxane emulsion containing hydroxy functional group, 3 to 5 portions of hydrophobic organic silicon modified emulsion, 0.15 to 0.2 portion of smooth flow agent, 0.85 to 0.95 portion of film forming assistant, 0.1 to 0.2 portion of preservative, 0.1 to 0.2 portion of mildew preventive, 0.8 to 1 portion of ethylene glycol, 5 to 7 portions of hydrophobic agent, 0.1 to 0.2 portion of thickening agent, and 23 to 25 portions of deionized water. 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 zero formaldehyde, benzene and heavy metals, has low VOC, and is typical environment-friendly paint.

Description

technical field [0001] The invention belongs to coatings and a preparation method thereof, and relates to an 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 anti-graffiti and anti-sticking coatings are produced, and currently commercially available anti-sticking coatings mainly take acrylic acid emulsion as a film former, and are processed with various additives. The UV resistance is poor, the weather resistance is also poor, the water resistance, acid and alkali resistance, and solvent resistance are poor, and the hardness of the paint film is not ideal. poor. Contents of the invention [0003] The purpose of the present invention is to provide a kind of different from the...
