Embodiment 1

[0016] Embodiment 1: A kind of anti-graffiti coating suitable for outdoor facilities of this example, its component and mass parts are: soybean oil polyurethane dispersion (solid content 30%) 42 parts, methacrylic acid-2,2,2 - 23.8 parts of trifluoroethyl ester, 28 parts of pigment and filler, 6 parts of auxiliary agent, and 0.2 part of initiator.

[0017] Its preparation method is:

[0018] a. Add soybean oil, hydrogen peroxide and formic acid into the reactor by weight ratio, keep the temperature of the system at 40°C for 24 hours, and obtain liquid A after removing moisture; add liquid A, measured isopropanol, methanol and fluoroboric acid into In the reactor, keep the temperature of the system at 50°C for 2 hours to remove moisture to obtain liquid B; add liquid B, isophorone diisocyanate, and 2,2-dimethylolpropionic acid into the reactor, under nitrogen protection Under the condition of mechanical stirring, react at 78°C for 2 hours, then add triethylamine and distilled...

Embodiment 2

[0020] Embodiment 2: A kind of anti-graffiti coating suitable for outdoor facilities of this example, its component and mass parts are: 45 parts of soybean oil polyurethane dispersion liquid (solid content 30%), 12 parts of hexafluorobutyl methacrylate , 13.8 parts of dodecafluorobutyl methacrylate, 22 parts of pigments and fillers, 7 parts of additives, and 0.2 parts of initiator.

[0021] Its preparation method is:

[0022] a. Add soybean oil, hydrogen peroxide and formic acid into the reactor according to the weight ratio, keep the system temperature at 50°C and react for 23 hours, and obtain liquid A after removing moisture; add liquid A, measured isopropanol, methanol and fluoroboric acid into In the reactor, keep the system temperature at 55°C for 2 hours to remove moisture to obtain liquid B; add liquid B, isophorone diisocyanate, and 2,2-dimethylolpropionic acid into the reactor, under nitrogen protection Under the condition of mechanical stirring, react at 78°C for ...

Abstract

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.

Description

technical field [0001] The invention relates to an industrial coating, in particular to an anti-graffiti coating suitable for outdoor facilities and a preparation method thereof. Background technique [0002] In recent years, graffiti, as a street culture, has gradually become known to people. However, malicious graffiti has also become a major source of influence on the cleanliness of urban civilization. Graffiti paints are generally composed of water-based, oil-based inks or dyes, which often contain adhesives, which have high adhesion on general surfaces, so it is often difficult to remove them by physical or chemical methods after malicious graffiti is fixed, and There is a risk of damage to the surface. It is obviously a more effective and convenient method to apply anti-graffiti paint to the surface in advance, and it can also have certain anti-corrosion and protection functions. Anti-graffiti paint belongs to a kind of isolation protective paint. The main differen...
