Description

TECHNICAL FIELD

[0001] The present application relates to the field of paint technology, in particular to a real stone paint and a preparation method and application thereof. BACKGROUND

[0002] At present, the domestic mainstream stone-imitating paint includes real stone paint, water-in-water, water-in-sand and sand-in-sand products. The real stone paint is a kind of paint which is similar to marble and is prepared by using natural sand with different colors and particle sizes and a base material. The real stone paint has a good imitation effect. Although water-in-water, water-in-sand, sand-in-sand and other stone-imitating paints have been derived in recent years, the real stone paint is still the first choice of most real estate companies due to its high cost performance and convenient construction.

[0003] The consumption of conventional real stone paint is 3-5 kg / m 2 , the coating film is thick, the drying rate is slow, the color difference between the wet film and the dry film is large, the color adjusting period of the product is long, the efficiency is slow, the delivery of the production end is affected. The high consumption of construction makes the construction efficiency low, and the color difference is prone to occur when the site temperature is different. In addition, the hiding power of the real stone paint is poor, and the mottling phenomenon is prone to occur when the construction is improper, thereby affecting the delivery of the construction site. In addition, in order to achieve a better decorative effect, 10-40 mesh coarse particle size natural sand is often used as decorative sand in the formula. Due to the high construction air pressure of the real stone paint, the decorative sand is prone to rebound and drop during spraying. Not only does it affect the construction experience of workers, waste materials, affect the environment, increase costs, but also makes the coating film have poor flatness and high porosity, so that the coating film is prone to dust and dirt, thereby affecting the weather resistance of the product.

[0030] The basic principle of the present application is as follows:

[0031] 1) Using natural sand as aggregate can improve the durability and weather resistance of the coating; in addition, the natural sand with secondary distribution is screened and classified, so that the size and texture of the sand particles are more uniform, which can ensure the uniform distribution of the texture and color of the real stone paint coating, thereby improving the hiding power of the coating.

[0032] 2) The synthesized iron oxide pigment has high purity, uniform and neat particle size, wide color spectrum, multiple colors, low cost, non-toxicity, excellent dispersibility, coloring property, light resistance and weather resistance, which can improve the toning property and hiding power of the coating; the stone powder has good weather resistance, high whiteness, good thermal stability, non-toxicity, non-odor and good dispersibility, which can improve the toning property and hiding power of the coating.

[0104]

[0105] Table 2 shows the performance test results of the stone paint prepared in Examples 1-3.

[0106] Table 3. Performance test results of the stone-like paints prepared in Comparative Examples 1–7

[0107]

[0108]

[0109] Table 3 shows the performance test results of the stone-like paints prepared in Comparative Examples 1 to 7. As can be seen from Table 3, in Comparative Example 1, only BENAQUA 4000 bentonite was used for thickening, resulting in only low shear viscosity. This led to excessively high thixotropy and a too-fast drying rate, thus affecting the paint's workability, storage stability, drying time, initial crack resistance, and sand shedding rate. In Comparative Example 2, only cellulose ether Prime was used... Thickening agent 3500 possesses a certain medium-low shear viscosity, but its strong water retention and binder migration properties result in a slow drying rate, thus affecting the paint's workability, drying time, temperature-sensitive color difference, and sand shedding rate. In Comparative Example 3, only polyurethane thickener BLJ-18S was used, exhibiting extremely high high shear viscosity without medium-low shear viscosity. Simultaneously, its poor water retention and strong binder migration properties lead to a fast drying rate, affecting the paint's workability, storage stability, drying time, early crack resistance, temperature-sensitive color difference, and sand shedding rate. In Comparative Example 4, Clariant's wetting agent LCN-407, with a high hydrophilic-lipophilic balance (HLB) value, was used. Its strong hydrophilicity and poor compatibility with the binder negatively impact the paint's workability, storage stability, water resistance, and temperature-sensitive color difference. In Comparative Example 5, no... Using ultrafine calcite powder and iron oxide pigments as toners lowers the pigment volume concentration (PVC) of the coating, reduces film density, decreases hiding power, and enhances texture, thus affecting the coating's workability, drying time, stain resistance, hiding power, temperature-sensitive color difference, and sand shedding rate. In Comparative Example 6, without the addition of 40-80 mesh natural sand, the pigment volume concentration of the coating is higher, improving film smoothness but deteriorating texture, thus affecting the coating's workability, storage stability, drying time, resistance to artificial weathering, initial crack resistance, and flexibility. In Comparative Example 7, the absence of thin rock flakes requires a higher consumption rate to achieve the desired embellishment effect, thus affecting the coating's workability, drying time, stain resistance, initial crack resistance, hiding power, resistance to artificial weathering, temperature-sensitive color difference, and sand shedding rate.

[0110] The true stone paint provided by the present application uses bentonite as a main thickening agent, is matched with a high molecular weight cellulose ether and a polyurethane thickening agent, and has excellent storage stability and spraying performance, can reduce the migration of a base, and can accelerate the drying rate of a coating film, thereby reducing the color difference between a dry coating film and a wet coating film and the temperature change color difference; the true stone paint uses calcite powder and iron oxide pigments to assist color matching, adds a large proportion of 120-180 mesh and 80-120 mesh natural sand as aggregate, increases the hiding power of the coating, reduces the consumption of the coating from 3-5 kg / m 2 to 1.5-1.8 kg / m 2 , has high efficiency in construction, and has a dense coating film, can avoid the problems of a bare surface and a coating film caused by improper spraying, and improves the delivery rate of a product construction site; the true stone paint uses 0.5-1.5 mm thin rock pieces to replace 10-40 mesh natural sand to provide a decoration effect of the true stone paint, effectively reduces the construction sand dropping, reduces the loss of the coating, is environmentally friendly and pollution-free, the thin rock pieces have good adhesion, the coating film has high flatness, and the overall weather resistance of the coating film is improved.
