Description

Technical Field

[0001] The invention relates to a high-fidelity water-resistant real stone paint coating and a preparation process thereof. Background Art

[0002] Real stone paint is a kind of paint with decorative effect similar to marble and granite. It is mainly made of natural stone powder of various colors and is applied to the imitation stone effect of building exterior walls, so it is also called liquid stone. It is a thick paste paint with strong decorative effect and imitation of natural stone, marble and granite. It has natural color and the texture of natural stone. Various grid designs can provide various three-dimensional pattern structures, which can visually highlight the elegance and solemn beauty of the entire building. It is the best substitute for dry hanging stone on the exterior wall. Real stone paint is fireproof, waterproof, acid and alkali resistant, and pollution resistant. It is non-toxic, odorless, has strong adhesion, and never fades. It can effectively prevent the harsh external environment from eroding the building and extend the life of the building. Because real stone paint has good adhesion and freeze-thaw resistance, it is suitable for use in cold areas.

[0003] Real stone paint is acid and alkali resistant, corrosion resistant, non-flammable, highly decorative, and weather resistant. However, the emulsion content in real stone paint is relatively high. The emulsion used in traditional real stone paint contains more emulsifiers. In addition, the real stone paint additives contain a large number of hydrophilic groups, which leads to a high water absorption rate of real stone paint. Real stone paint generally has a thicker coating. When it rains continuously, the absorbed water is not easy to discharge. The coating that has been soaked in water for a long time will turn white and soften, and the color will become lighter. Although the color will basically return to its original state after the weather clears up and the coating dries, the color will change significantly after repeated reciprocating. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a high-fidelity water-resistant real stone paint coating and a preparation process thereof.

[0005] A high-fidelity water-resistant real stone paint coating comprises: an anti-alkali sealing primer, a real stone paint middle layer and a finishing paint which are arranged in sequence.

[0006] Preferably, the alkali-resistant primer of the present invention comprises acrylic emulsion, water, and other additives in amounts of 60 parts, 35 parts, and 5 parts by weight, respectively.

[0007] Preferably, the middle layer of the real stone paint of the present invention includes silicone acrylic emulsion, natural colored stone sand, thickener, plasticizer, and other additives, with the mass parts being 30 parts, 65 parts, 3 parts, 1 part, and 1 part respectively.

[0008] Preferably, the finishing paint of the present invention comprises polyacrylate, butyl acetate, xylene, UV inhibitor, and other additives in amounts of 60 parts, 18 parts, 20 parts, 1 part, and 1 part, respectively.

[0009] Preferably, the polyacrylate of the present invention is prepared by mixing coating, ink, resin and adhesive.

[0010] A preparation process of a high-fidelity water-resistant real stone paint coating. Firstly, add acrylic emulsion, additives, etc. and stir evenly, then add water and stir evenly to prepare alkali-resistant sealing primer; First add silicone acrylic emulsion, thickener, plasticizer, and other additives and stir evenly, then slowly add natural colored sand and stir evenly to make the middle layer of real stone paint; Acrylate, butyl acetate, xylene, UV-resistant agent and other additives are mixed and stirred evenly to prepare a topcoat; The anti-alkali sealing primer, the real stone paint middle layer and the topcoat are mixed and stirred in the ratio of 1:1:1 to obtain the real stone paint coating.

[0011] The invention adopts a reasonable combination of two emulsions, so that the prepared real stone paint product has high paint film hardness, no water whitening phenomenon, no yellowing, high bonding strength and good weather resistance.

[0012] The present invention selects the best coarse and fine sand particle size ratio of natural colored sand through experiments, and adds a proper amount of natural rock flakes. The prepared real stone paint product has less sand loss during the spraying process, a dense coating, a natural stone texture, and an ideal simulation effect.

[0013] The product of the invention has a simple preparation method, excellent construction performance, good crack resistance, acid and alkali resistance, corrosion resistance and other properties, is non-toxic, tasteless, has no radioactive pollution, is harmless to the human body, and is safe and environmentally friendly.
