Problems solved by technology

There are two types of these anti-graffiti coatings. First, the active ingredients of anti-graffiti are only physically mixed with other ingredients in the paint film. The function is reduced or even disappeared, and the shortcomings of dust adhesion due to the free distribution of active ingredients on the surface of the paint film
Second, the active ingredients of the anti-graffiti and other ingredients have undergone chemical cross-linking in the paint film, such as silox

Example Embodiment

[0034] Example 1

[0035] First prepare the anti-sticking and anti-graffiti coating component A of the present invention:

[0036] Take each component according to the weight shown in Example 1 in Table 1. The preparation method is as follows:

[0037] Step 1: Add 65.0kg of JF-2X fluororesin and 15.0kg of butyl acetate solvent into the paint mixing container, stir at low to medium speed for 3 minutes, and add 0.4kg of Deqian 5300 defoamer and 0.3 of TEGO450 leveling agent under stirring. kg, after adding, continue to stir at medium speed for more than 3 minutes.

[0038] Step 2: Add 3.0 kg of TEGO5000 modified hydroxyl-containing polydimethylsiloxane resin from Tego Company to the mixture obtained in step one under strong stirring, and continue to vigorously stir for more than 15 minutes after the addition.

[0039] Step 3: Add 25.0kg of PMA solvent under low to medium speed stirring, and continue stirring for more than 3 minutes at low to medium speed after adding. After passing the ...

Example Embodiment

[0043] Example 2

[0044] According to the weight of each component in Example 2, the method described in Example 1 was repeated to prepare component A and component B of the anti-sticking and anti-graffiti coating. According to the weight ratio, component A: component B=90.5:15.0 (OH:NCO=1:1.06), mix it evenly and let it stand for more than 5 minutes for brushing. The surface dry time does not exceed 1 hour, and the hard-drying time is 24 hours. The performance test results are shown in the corresponding data of Example 2 in Table 2. If spraying is used for the construction method, an additional 15% PMA or polyurethane paint thinner is required, and the performance test results are the same.

Example Embodiment

[0045] Example 3

[0046] According to the weight of each component in Example 3, the method described in Example 1 was repeated to prepare component A and component B of the anti-sticking and anti-graffiti coating. According to the weight ratio, component A: component B=74.3:17.0 (OH:NCO=1:1.1), mix evenly and let it stand for more than 5 minutes for brushing. The surface dry time does not exceed 1 hour, and the actual drying time is 24 hours. The performance test results are shown in the corresponding data of Example 3 in Table 2. If spraying is used in the construction method, an additional 20% PMA or polyurethane paint thinner is required, and the performance test results are the same.

Abstract

The invention relates to an anti-paste and anti-graffiti fluorocarbon coating which is prepared by mixing a component A and a component B in a proportion of OH/NCO=1:(1.0-1.1), wherein the component A comprises the following components in percentage by weight: 50-65 percent of FEVE fluororesin, 1-3 percent of modified polydimethylsiloxane resin containing hydroxide radicals, 8-15 percent of butyl acetate, 15-25 percent of propylene glycol methyl ether acetate, 0.2-0.4 percent of defoaming agent and 0.1-0.3 percent of flatting agent; and the component B is prepared by mixing 80 parts of IPDI isocyanate curing agent or GDI multifunctional isocyanate curing agent by weight and 20 parts of anhydrous butyl acetate by weight. The coating has high film crosslinking density and hardness, low surface tension, extremely strong permeability resistance and excellent anti-paste and anti-graffiti performance, and intractable oil pen graffiti can also be easily and completely wiped out. The coating also has excellent wear-resistant, scouring resistant and weather resistant properties and is suitable for long-term outdoor use. The coating can be painted and can also be sprayed after being diluted by adding 10-20 percent of PMA or polyurethane coating diluent.

Description

technical field [0001] The invention relates to a coating, in particular to a composition of an anti-sticking and anti-graffiti coating and a method for using the same. Background technique [0002] All kinds of buildings and structures, especially public places, have been plagued by various small advertisements and graffiti for a long time, affecting the appearance of the city. In order to solve this problem, people have adopted various methods and invented various coatings to be coated on the surfaces of these buildings or structures, hoping to achieve the purpose of anti-sticking and anti-graffiti, and achieved certain effects. Most of these coatings are made by compounding organosiloxane or mineral oil and other materials by using the non-stick properties of organic silicon or mineral oil, such as water-based anti-graffiti coatings with water-based fluorosilicone emulsion as film-formers, acrylic siloxane Anti-graffiti coatings, mineral oil anti-graffiti coatings, silic...
