preparation example Construction

[0041] The preparation method of the anti-sticking anti-graffiti water-based fluorocarbon coating with super weather resistance of the present invention, the steps are as follows:

[0042] Step 1, taking each raw material by composition and parts by weight;

[0043] Step 2, uniformly mixing the adhesion enhancer and ethanol at a mass ratio of 1:4 to obtain the adhesion enhancer dispersion;

[0044] Step 3, uniformly mixing the compound anti-graffiti agent with the remaining ethanol to obtain a compound anti-graffiti agent dispersion;

[0045] Step 4. First mix the compound fluorocarbon emulsion, ethylene glycol and deionized water evenly, then add water-based film-forming aids and continue to mix evenly, then add bactericide, defoamer, compound anti-graffiti agent dispersion in turn, and mix Evenly, then add adhesion enhancer dispersion, mix evenly, finally add leveling agent, mix evenly, filter, seal, and get anti-sticking anti-graffiti water-based fluorocarbon coating with ...

Embodiment 1

[0048] The anti-sticking and anti-graffiti water-based fluorocarbon coating with super weather resistance consists of 200 parts by weight of compounded fluorocarbon emulsion, 20 parts by weight of Eastman water-based coalescent, 30 parts by weight of deionized water, 15 parts by weight of Ethylene glycol, 20 parts by weight of ethanol, 1.0 parts by weight of water-based silicone defoamer RC115, 2.5 parts by weight of leveling agent dimethyl polysiloxane, 2.5 parts by weight of adhesion enhancer water-based ultra-high molecular weight poly Dimethylsiloxane, the bactericide Aoqi CMC of 1 weight part and the composite antigraffiti agent of 15 weight parts are formed;

Abstract

The invention relates to anti-adhesion anti-scrawling water-based fluorocarbon coating with super weatherability as well as a preparation method thereof, and belongs to the technical field of coating.The technical problems in the prior art that the anti-adhesion anti-scrawling coating causes pollution to the environment and is liable to pulverization at a low temperature. The fluorocarbon coatingconsists of 100 to 200 weight parts of a compound fluorocarbon emulsion, 5 to 20 weight parts of a water-based film-forming cosolvent, 15 to 30 weight parts of deionized water, 5 to 15 weight parts of glycol, 5 to 15 weight parts of ethanol, 0.5 to 2.0 weight parts of a water-based organic silicon defoaming agent, 0.5 to 2.5 weight parts of a leveling agent, 1 to 5 weight parts of an adhesive force enhancer, 0.5 to 2 weight parts of a bactericide and 5 to 15 weight parts of a compound anti-scrawling agent. The fluorocarbon coating does not contain toxic and / and harmful substances, has excellent fouling resistance, weather resistance and wear resistance, and is particularly suitable for long-time use in the hostile outdoor environment.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an anti-sticking and anti-graffiti water-based fluorocarbon coating with super weather resistance and a preparation method thereof. Background technique [0002] Graffitiers have many methods of scribbling and pasting. The tools include marker pens, brushes, brushes, etc., and the materials include paint, ink, glue, paste, and stickers. In the city, whether it is the utility poles, light boxes, station signs, guardrails on the street, or the walls, stairs, security doors, and newspaper boxes in the corridors, you can see small advertisements graffitied everywhere. This uncivilized phenomenon not only seriously affects the appearance of the city, but also causes various illegal acts to breed and spread. However, due to the size of the city, especially the behavior of scribbling and scribbling usually occurs at night, it is beyond the reach of managers and it is diffi...
