Description

Technical Field

[0001] The invention relates to the technical field of coatings, in particular to a light-weight real stone paint. Background Art

[0002] Real stone paint is a thick paint. Buildings decorated with real stone paint have the effect of natural sand and stone. The decorative feeling is vivid, lifelike, solemn and elegant, which can give people the effect of returning to nature. Therefore, it is widely loved by people and is increasingly used in the exterior wall decoration of various buildings.

[0003] However, the main source of real stone paint is the large amount of natural colored sand. The large differences between batches lead to large color differences in real stone paint, and low-quality and low-content emulsions are used to reduce costs. The decorative effect is single color, rough surface, easy to get dust and dirt. It is easy to produce flowery, color difference, rain marks, and poor stain resistance. During construction, the square meter usage is large, sand falling is serious, and materials are wasted. During production, the batches of colored sand vary greatly, and production and color matching are difficult.

[0004] The colorful imitation stone paint has poor initial water whiteness, difficult to control the color point state, low production efficiency, many color point sizes and types, long color adjustment cycle, high control requirements for spraying equipment during construction, and difficulty in high-rise residential construction.

[0005] Specifically, the main raw material of traditional real stone paint relies on natural colored sand, and in recent years, natural colored sand resources have become increasingly depleted, and blind mining has led to a series of problems such as serious air pollution and climate deterioration. In addition, natural colored sand itself has a large specific gravity, which makes the real stone paint heavy and increases the difficulty of construction, resulting in a large amount of real stone paint in construction, which not only wastes resources but also poses certain safety hazards, and can no longer meet China's national conditions for energy conservation and environmental protection. For this reason, a lightweight real stone paint is proposed.

[0006] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field. Summary of the invention

[0007] The present invention aims to solve at least one of the technical problems in the prior art. To this end, an object of the present invention is to provide a light real stone paint.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A lightweight real stone paint is prepared from the following raw materials in parts by weight: 0.1-0.2 parts of hydroxyethyl cellulose, 0.1-0.2 parts of modified bentonite, 0.1-0.2 parts of dispersant, 0.1-0.2 parts of defoamer, 0.1-0.2 parts of pH regulator, 1-1.5 parts of propylene glycol, 0.5-0.8 parts of alcohol ester dodecahydrate, 12-16 parts of pure acrylic emulsion, 0.2-0.3 parts of bactericide, 0.1-0.2 parts of thickener, 2-3 parts of flexible ultra-thin fine rock slices, 5-10 parts of hollow glass microspheres, and 60-65 parts of natural colored sand.

[0010] As a further optimization scheme of the present invention, the chemical formula of the modified bentonite is Al2H2Na2O13Si4.

[0011] As a further optimization scheme of the present invention, the defoamer is selected from one or two of mineral oil defoamers, polymer defoamers or silicone defoamers.

[0012] As a further optimized solution of the present invention, the pH regulator is one of 10% sodium hydroxide aqueous solution, 2-amino-2-methyl-1-propanol, ammonia water or 10% potassium hydroxide aqueous solution.

[0013] The bactericide is one or more of isothiazolinones, formaldehyde-releasing agents and benzimidazoles.

[0014] As a further optimization scheme of the present invention, the pure acrylic emulsion is an acrylic polymer.

[0015] As a further optimized solution of the present invention, the thickener is polyurethane with a solid content of 50-60%.

[0016] As a further optimization scheme of the present invention, the flexible ultra-thin fine rock slices are water-based ultra-fine colored rock slices, and the particle size of the water-based ultra-fine colored rock slices is 0.5-0.9 mm and the thickness is 0.05-0.10 mm.

[0017] As a further optimization scheme of the present invention, the mesh number of the hollow glass micro powder is 80-120 meshes, and the mesh number of the natural colored sand is 40-120 meshes.

[0018] As a further optimization scheme of the present invention, a method for preparing a lightweight real stone paint comprises the following steps:

[0019] Step 1: At a stirring speed of 400-600r / min, add water, hydroxyethyl cellulose and modified bentonite in sequence, stir and disperse for 10 minutes, then slowly add dispersant, defoamer and pH adjuster in sequence, increase the speed to 600-800r / min, and stir and disperse for 5 minutes;

[0020] Step 2: Reduce the speed to 400-600r / min, slowly add pure acrylic emulsion, stir and disperse for 6-8 minutes, then slowly add alcohol ester 12, propylene glycol and fungicide at the same speed, stir and disperse for 5 minutes;

[0021] Step 3: Slowly add the polyurethane thickener at a speed of 800-1000r / min, stir and disperse for 5-10 minutes, increase the speed to 1500r / min, add flexible ultra-thin fine rock flakes, hollow glass beads, and natural colored sand, stir and disperse for 15 minutes, and you can get the lightweight real stone paint.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The lightweight real stone paint prepared by the present invention weighs only 1 / 3 of the traditional real stone paint, forming an extremely lightweight decoration system, which does not increase the load of the building body, effectively reduces the load of the building exterior wall, and thus eliminates the risk of falling off. Compared with traditional real stone paint, through the support of small color dots, its texture is more intense, with a richer and more natural imitation stone effect.

[0024] The lightweight real stone paint of the present invention can be constructed using a real stone paint spray gun, which greatly improves the construction efficiency, makes the construction process more convenient and quick, and adapts to various climate environments, has stable quality, and can effectively extend the service life of building finishes. The paint film is more dense, the surface is smooth, and the self-cleaning property is good. Compared with traditional real stone paint, it has better anti-fouling performance. For the repair and rework of the building body, the present invention can effectively improve the color difference problem of the decorative surface and maintain the overall beauty. At the same time, the unit area consumption is small, but the coating area is 2-3 times that of traditional real stone paint, which reduces secondary handling and saves costs. At the same construction site, the lightweight real stone paint material of the present invention can save 50-60% of the freight, which has significant economic advantages.

In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.
