Embodiment 1

[0027] A weather-resistant self-healing coating, the mass percentage of each component of the coating is: styrene-acrylic emulsion (polyacrylic emulsion) 11%, color filler (light calcium carbonate 20% and heavy calcium carbonate 32.5%), preservative (Methyl benzimidazole carbamate) 0.15%, defoamer (xylene solution containing 5% (volume fraction) of silicone oil) 1.5%, film-forming aid (dodecyl alcohol ester) 0.55%, thiourea dioxide microcapsules 4%, vat dye microcapsules 3%, and the balance is water.

[0028] The vat dye is indigo.

[0029] The preparation method of described weather resistance self-repairing paint, comprises the steps:

[0030] Add styrene-acrylic emulsion, color fillers, preservatives, defoamers, film-forming aids, thiourea dioxide microcapsules, and vat dye microcapsules to water in sequence, and then stir and disperse to obtain the weather-resistant self-healing coating.

Embodiment 2

[0032] A weather-resistant self-healing coating, the mass percentage of each component of the weather-resistant self-healing coating is: styrene-acrylic emulsion (polyacrylic emulsion) 15%, color filler (light calcium carbonate 20% and heavy calcium carbonate 32.5% ), preservative (benzimidazole methyl carbamate) 0.15%, defoamer (xylene solution containing 5% (volume fraction) of silicone oil) 1.5%, film-forming aid (dodecyl alcohol ester) 0.55%, 4% thiourea oxide monomer, 3% vat dye monomer, and the balance is water.

[0033] Described vat dye is the same as embodiment case 1.

[0034] The preparation method of described weather resistance self-repairing paint, comprises the steps:

[0035] First add thiourea dioxide solid monomer into water, then add polyacrylic acid emulsion, color filler, preservative, and film-forming aid in sequence to form an emulsion coating on the surface of thiourea dioxide, and finally add vat dye monomer, and then stir to disperse. The weather-re...

Abstract

The invention belongs to the technical field of coatings, and in particular relates to a weather-resistant self-repairing coating and its preparation method and application. The weather-resistant self-repairing coating of the present invention is mainly composed of coating formula compounded with thiourea dioxide and vat dyes. The mass percentage of each component is: polyacrylic acid emulsion 5%-30%, color filler 20%-50%, anti-corrosion 0.1%~0.5% of antifoaming agent, 0.1%~0.5% of defoaming agent, 0.5%~1.0% of film-forming aid, 3-5% of thiourea dioxide monomer or thiourea dioxide microcapsule, vat dye monomer or vat dye microcapsule 2 ‑5%, the balance being water. After the weather-resistant self-repairing paint of the present invention is coated on the alkaline wall, it reacts with the alkaline substance in the wall, so as to repair the color of the wall and achieve the effect of deepening the color.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a weather-resistant self-repairing coating and its preparation method and application. Background technique [0002] After the paint is used for a period of time, it will inevitably fade and become lighter after being exposed to wind, sun and rain. The common practice in the prior art is to increase the service life by increasing the fastness of pigments and fillers, but the effect is not good, for example figure 1 As shown, the walls painted at the same time, because the second floor is protected by the eaves, the rain erosion is less, and the color is preserved more, while the first floor is not protected by the eaves, the rain erosion is more, and there are air-conditioning winds, etc., which intensify the color of degradation. [0003] The Chinese patent whose publication number is CN108715728A discloses a kind of highly wear-resistant and self-repairing scratc...
