Description

Technical Field

[0001] The invention belongs to the technical field of real stone paint, and in particular relates to a sand-wall-shaped real stone paint, a coloring method and application thereof. Background Art

[0002] At present, the color scheme of real stone paint on the market is mainly based on colored sand / white sand as the main color, and color paste is used to correct or adjust the color. The method of using colored sand will consume a large amount of natural colored sand, and the batch stability of natural colored sand is not high, and it is a non-renewable resource. Large-scale mining is not conducive to environmental protection. Without the use of topcoat varnish, the weather resistance and stain resistance of real stone paint cannot achieve satisfactory results. In addition, the production technology of real stone paint is highly mature, and the market has entered the stage of price competition. The low-price strategy cannot bring long-term competitive advantages to real stone paint. Only by focusing on the product itself and improving performance can the bottleneck of the real stone paint market be broken.

[0003] Therefore, the market urgently needs a method to improve the performance of real stone paint to help it get rid of low-price competition and break the vicious cycle. In order to improve the batch stability of existing real stone paint, reduce the use of natural colored sand, and improve the stain resistance and weather resistance of real stone paint. Summary of the invention

[0004] The invention aims to solve the problems existing in the prior art and provide a sand-walled real stone paint, a coloring method and its application. The present invention innovatively introduces water-based multi-color paint technology into the real stone paint formula system, thereby improving the performance of the real stone paint product. Among them, the most significant performance improvement includes the weather resistance and stain resistance of the real stone paint, which are also one of the key indicators that best reflect the product level after the real stone paint is completed.

[0005] The coloring method of the sand-walled real stone paint of the present invention has a simple process and is easy to operate, and effectively improves the shortcomings of existing real stone paint products in terms of weather resistance and stain resistance, as well as the batch stability problem caused by the large-scale use of natural colored sand. In addition, the coloring method has a wide range of applications, which can meet the small-scale coloring needs of retail stores and is also suitable for large-scale production in factories.

[0006] The first invention object of the present invention is:

[0007] A method for coloring a sand-walled real stone paint is provided, wherein the sand-walled real stone paint comprises the following raw material components in parts by weight:

[0030] A2. Place the sealed container in a shaking mixer;

[0031] A3. Set the shaking time to 5 to 10 minutes. After the shaking is over, the mixed soft spot coloring package is obtained;

[0032] The stirring and mixing method adopts a stepless speed mixer;

[0033] It includes the following mixing steps:

[0034] B1. Put colorful soft dots and appropriate amount of real stone paint into the container;

[0035] B2. Mix with a disperser and stir with a ribbon; the mixing speed is 50 to 200 rpm and the mixing time is 10 to 20 minutes (the larger the container capacity, the higher the mixing speed and the longer the mixing time required);

[0036] B3. After the stirring and mixing is completed, the mixed soft point coloring bag is obtained.

[0037] The color mixing method of the sand-walled real stone paint coating of the present invention is further optimized as follows:

[0038] The soft spot coloring package, the colorful hard spots and the remaining real stone paint described in step S2 are mixed by a stirring mixing method, the purpose of which is to provide the real stone paint with a coloring effect similar to that of coarse-grained colored sand.

[0039] The color mixing method of the sand-walled real stone paint coating of the present invention is further optimized as follows:

[0048] Provide an application of the aforementioned sand-walled real stone paint:

[0049] The sand-wall-like real stone paint is applied to the exterior wall of a building.

[0050] The sand-wall-like real stone paint is applied by spraying, such as by using a real stone paint spray gun.

[0051] The sand-walled real stone paint coating and the coloring method thereof of the present invention, its production process and production equipment can be compatible with water-based multi-color paint and traditional real stone paint, without the need for additional new equipment support. The sand-walled real stone paint coating of the present invention can be constructed by spraying, which is simple to operate and has a smooth construction process. The coloring method of the sand-walled real stone paint coating of the present invention can reduce the use of natural colored sand, improve batch stability, and significantly improve the weather resistance and stain resistance of the real stone paint. The method of the present invention is easy to produce and flexible to store, and is suitable for both retail and factory mass production. Compared with directly using color paste to color, the effect of this method is more transparent and the color is more realistic.

[0052] The invention discloses a sand-walled real stone paint, a coloring method and an application thereof, and specifically relates to the improvement of the performance of the real stone paint for building exterior walls in terms of color creation and coloring, stain resistance, surface stone imitation effect, etc. The water-based multi-color paint technology is creatively introduced into the real stone paint, thereby improving the performance of the real stone paint.

[0053] Because water-based multi-color paint uses modified cellulose and protective glue system, the stain resistance and weather resistance of the paint after film formation are better than those of real stone paint. This method adopts the method of preparing water-based multi-color paint into a semi-finished product of coloring points, and introducing water-based multi-color paint into the real stone paint formula system by the method of coloring real stone paint. Under normal circumstances, water-based multi-color paint can be toned using color paste and white sand, which can hardly use natural colored sand and can improve the stability of product effects. The water-based multi-color paint is prepared into colored color points, used as a toning raw material, and mixed with real stone paint, which can effectively replace natural colored sand and improve the batch stability of the color effect of real stone paint. In addition, after a certain proportion of colored color points are mixed, the stain resistance and weather resistance of real stone paint are significantly improved.

[0054] Water-based multi-color paint uses modified cellulose and protective glue system, and its pollution resistance and weather resistance after film formation are better than real stone paint. Usually, water-based multi-color paint can be toned by color paste and white sand, which almost does not require the use of natural colored sand and can also improve the stability of product effects.

[0055] In the technical solution of the present invention, a water-based multi-color paint is first prepared into a semi-finished color point, and then introduced into the real stone paint formula system by the method of coloring the real stone paint. First, the water-based multi-color paint is prepared into a color point, which is mixed with the real stone paint as a coloring raw material, which can effectively replace the natural colored sand; at the same time, it can also improve the batch stability of the color effect of the real stone paint. In addition, when a certain proportion of the color point is mixed, the pollution resistance and weather resistance of the real stone paint will be significantly improved.
