Technical Field

[0001] The present application relates to the technical field of surface treatment agents, and in particular, to a ceramic tile surface treatment agent composition and a preparation method thereof. Background Art

[0002] Using water-based paint to renovate ceramic tiles is an effective way to improve the appearance and life of ceramic tiles. However, since the ceramic tiles will have oil stains, soap scum, etc. on the surface after use, it is difficult for water-based paint to adhere to the ceramic tile surface well. In order to improve the adhesion of water-based paint to the ceramic tile surface, it is necessary to use a treatment agent to treat the ceramic tile surface. However, the existing treatment agents are either too alkaline, corroding the glaze of the ceramic tile, or it is difficult for the water-based paint to have a high adhesion after treatment. Summary of the invention

[0003] In order to solve the technical problem that the adhesion of water-based coatings after treatment with the above-mentioned treatment agent is still not high enough, the present application provides a ceramic tile surface treatment agent composition and a preparation method thereof.

[0004] This application adopts the following technical solutions:

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below.

[0027] Throughout the specification, unless otherwise specifically stated, the terms used herein should be understood as meanings commonly used in the art. Therefore, unless otherwise defined, all technical and scientific terms used herein have the same meanings as those generally understood by those skilled in the art to which the present invention belongs. In the event of a conflict, the present specification takes precedence.

[0028] On the one hand, the present application provides a ceramic tile surface treatment agent composition, which comprises the following raw material components, based on 100% by weight, 2-10% alkali, 0.5-3% complexing agent, 0.1-2% penetrant, 2-15% surfactant, 0.5-3% thickener, 0.3-4% grapefruit peel extract, and the balance is water;

[0029] The thickener has a structure as shown in the following formula (1):

[0030]

[0031] Wherein, R1 and R2 are independently selected from C1-C4 alkyl or hydrogen, R3 is selected from C6-C24 alkyl, R4 is selected from hydrogen or C1-C4 alkyl, n=6-20, a>0, b≥0.

[0032] The present application adopts the above-mentioned thickener having the structure shown in formula (1), which not only provides a thickening effect, but also enables the surface treatment agent composition to be more stably covered on the surface of the tile to be treated. The applicant has found that after the treated tiles are cleaned, the water-based paint has a higher adhesion on the tiles.

[0033] The thickener represented by formula (1) can be prepared by the following method: 1 CO(OCH2CH2) n OR 3 With monomer CH2=CR 2 COOR 4 Add a certain amount of molar ratio to the organic solvent and mix evenly, add an initiator to initiate polymerization at a certain temperature, and remove the organic solvent to obtain the thickener of the present application. 1 , R 2 , R 3 , R 4 and n have the same meanings as above.

[0034] In a preferred embodiment of the present application, the values ​​of a and b satisfy that the value of b / a does not exceed 20%. In a more preferred embodiment, the values ​​of a and b satisfy that the value of b / a does not exceed 15%. Further preferably, the value of b / a is not less than 5%. For example, the value of b / a can be 5%, 5.5%, 6%, 6.5%, 7%, 7.5%, 8%, 8.5%, 9%, 9.5%, 10%, 10.5%, 11%, 11.5%, 12%, 12.5%, 13%, 13.5%, 14%, 14.5%, 5%, etc., not limited to the above examples.

[0035] In a preferred embodiment of the present application, the alkali is selected from one or more of sodium carbonate, sodium silicate, sodium hydroxide, potassium carbonate and potassium hydroxide. In the present application, more preferably, when the alkali is selected from one or more of sodium carbonate, sodium silicate and potassium carbonate, the weight percentage of the alkali can be 5-10%, and when the alkali is selected from sodium hydroxide and / or potassium hydroxide, the weight percentage of the alkali can be 2-5%.

[0036] In a preferred embodiment of the present application, the complexing agent is selected from one or more of sodium gluconate, disodium EDTA, tetrasodium EDTA and diethylenetriamine pentacarboxylate. In the present application, the complexing agent is used to complex the metal ions in the oil stains containing metal ions on the surface of the tile to prevent the metal ions from being adsorbed on the cleaned tile surface.

[0037] In a preferred embodiment of the present application, the above-mentioned penetrant has a structure as shown in the following formula (2):

[0038]

[0039] Among them, m=2-5.

[0040] The penetrant represented by formula (2) can be obtained by a ring-opening reaction of tert-butyl alcohol and ethylene oxide.

[0041] The penetrant of the present application has the above structure, and it is found that the penetrant has better permeability than the penetrant JFC on the market. This may be because the three methyl groups in the tert-butyl structure of the penetrant of formula (1) face outwards, which has lower surface energy and can penetrate better.

[0042] In a preferred embodiment of the present application, the above-mentioned surfactant is selected from one or more of nonionic surfactants, anionic surfactants, amphoteric surfactants and cationic surfactants. For example, the nonionic surfactant can be AEO-9, AEO-15, peregal O, AEO-10, Tween 60, Tween 80, etc.; the anionic surfactant can be sodium dodecylbenzene sulfonate, sodium dodecyl sulfate, sodium dodecyl sulfonate, sodium dodecyl carboxylate, etc.; the amphoteric surfactant can be dodecylethoxysulfobetaine, dodecyldimethylhydroxypropylsulfobetaine, dodecyldimethylsulfopropylbetaine, etc.; the cationic surfactant can be octadecyltrimethylammonium chloride, dodecyltrimethylammonium chloride, octadecylbenzyldimethylammonium chloride, etc.

[0043] In a more preferred embodiment of the present application, the above-mentioned surfactant contains at least a nonionic surfactant. In the present application, the surfactant can be a combination of a nonionic surfactant and an anionic surfactant, the weight ratio of which is 1:0.1-10, or a combination of a nonionic surfactant and an amphoteric surfactant, the weight ratio of which is 1:0.1-10.

[0044] In a preferred embodiment of the present application, the weight content of the grapefruit peel extract is 0.5-2%. The main component of the grapefruit peel extract is naringin, which has a structure shown in the following formula (3).

[0045] The addition of grapefruit peel extract to the tile treatment composition of the present application has shown a better treatment effect, which may be related to the high polarity of phenolic hydroxyl groups and polyhydroxyl groups in naringin.

[0046] On the other hand, the present application proposes a method for preparing the tile surface treatment agent composition described in any of the above embodiments, comprising: adding alkali to water, mixing evenly, and then sequentially adding a complexing agent, a penetrant, a surfactant, a thickener and a grapefruit peel extract, and mixing evenly to obtain the composition.

The ceramic tile was cut into small tiles of 10cm×5cm and placed outdoors in a ventilated and shaded environment for 10 days.

[0084] Small tile test: Apply the tile treatment agent of this application on the small tiles and soak them for 1 hour, rinse with clean water and dry, then apply the water-based tile glass paint (Sanqing Company) on the clean small tile surface with a film thickness of 30±2μm, observe whether the film layer has obvious shrinkage holes and other poor wetting conditions, and use the hundred-grid method to test the adhesion of the film layer after 48 hours. If obvious shrinkage holes and other poor wetting conditions appear, it means that the oil stains at that location have not been removed cleanly. Test 20 small tiles with each tile surface treatment agent to determine the number of small tiles with no poor wetting, a small amount of poor wetting, and obvious poor wetting. Soak in clean water as a blank example. The results are shown in Table 1 below, where the adhesion level is 1-5, with level 5 being the best and level 1 being the worst.
