The invention discloses a water-based anti-doodling paint and a preparation method thereof. The water-based anti-doodling paint is used for solving the problems of not environmental protection, no doodling and no erasing of the anti-doodling paint. The water-based anti-doodling paint is prepared from the following components in percentage by weight: 0.5-1.5% of dispersant, 0.1-0.3% of defoamer, 0.05-0.15% of wetting agent, 1-3% of coalescing agent, 20-35% of EVA emulsion, 9-29% of fluorosilicon resin, 1-12% of fluorine-containing nanosilicon dioxide dispersion liquid, 0.5-2% of coupling agent and 23-33.5% of pigment filler. The water-based anti-doodling paint is environment-friendly and erasable.

The invention relates to a waterborne two-component adhesion and doodling prevention coating, which is prepared by mixing a component A and a component B according to the proportion of NCO / OH=1.5-2, wherein the component A is prepared from the following components in part by weight: 60 to 80 parts of waterborne polyurethane, 0.3 to 0.6 part of dispersing agent, 0.4 to 0.8 part of defoaming agent, 0.1 to 0.5 part of wetting agent, 1 to 5 parts of modified hydroxyl polydimethylsiloxane resin, 3 to 7 parts of waterborne wax emulsion, 0.6 to 1 part of polyurethane thickening and flatting agent and 5 to 35 parts of water; the modified hydroxyl polydimethylsiloxane resin comprises 22.5+ / -0.5 percent of NCO in percentage by weight; and the component B is hydrophilic aliphatic polyisocyanate of hexamethylene diisocyanate. The coating has equivalent permanence doodling prevention performance with an oily polyurethane doodling prevention coating and an oily fluorocarbon doodling prevention coating, and also has the characteristics of wear resistance, washing resistance, weather fastness and environmental protection.

The invention relates to preparation of fluorine-containing organosilicone modified anti-graffiti paint, in particular to preparation of organosilicone polyester modified cyclopropyl resin. The resin,namely cationic resin, can be used in both aqueous paint and electrophoretic paint, plays an anti-graffiti self-cleaning role in the electrophoretic paint, and is prepared from a fluorine-silicon modified emulsion and high-performance color paste in a ratio of 6:1. The preparation has the advantages that paint products have high storage stability; the paint has high salt spray resistance, high weather resistance and high functionality after electrophoretic coating, and is applicable to painting of kitchens and places with high self-cleaning requirements; the paint is water-based two-componentanti-graffiti electrophoretic paint, and is convenient to apply, environmentally friendly and safe to use; the surfaces of boards are smooth and bright, the functionality is high, and the stability of tank liquor is also high; coatings have high mechanical property, acid-alkali resistance, weather resistance and salt-pray resistance.

The invention relates to an industrial coating, in particular to an anti-doodling coating for an outdoor facility and a preparation method of the anti-doodling coating. The anti-doodling coating mainly aims at solving the technical problems that a doodling coating in the prior art contains a bonding agent, has higher attaching power on a general surface, and is relatively difficult to remove by using a physical or chemical method after setting in case of vicious doodling, and the surface is prone to being damaged. The anti-doodling coating disclosed by the invention is an oxidative dry type single-component waterborne coating, and comprises the following components by part by mass: 30-65 parts of fluorinated polyacrylate-modified soybean oil polyurethane resin, 1-10 parts of additive, 15-30 parts of pigment and filler and 10-25 parts of water.
