Description

Technical Field

[0001] The invention relates to the technical field of coatings, and in particular to an airless spraying textured water-in-water art coating with high-efficiency mildew resistance and a preparation method thereof. Background Art

[0002] In the field of architectural decoration, decorative materials that pursue naturalness and beauty have always been favored. Water-in-water paint, as a paint that can simulate the texture of natural stone, has been widely used in the market in recent years. However, the construction process of traditional water-in-water paint is relatively complicated. It is usually necessary to spray water-in-water paint again on the basis of the pre-sprayed sand-containing texture paint to achieve the desired imitation stone effect. This multi-layer construction process not only increases the construction difficulty and time cost, but may also cause potential quality problems at the joints between layers.

[0003] On the other hand, although water-in-sand paint simplifies the construction process to a certain extent, it can directly form a stone-like texture because it contains sand particles, without the need for additional spraying of sand-containing texture paint. However, water-in-sand paint also has significant defects in practical applications. Due to its sand-containing characteristics, the "sand leakage" phenomenon is prone to occur during the construction process, that is, sand particles fall off from the paint, affecting the integrity and aesthetics of the coating. In addition, water-in-sand paint is also prone to stratification, which further reduces the stability and durability of the coating. At the same time, the high construction consumption also increases the material cost, limiting its wider application.

[0004] More importantly, most water-in-water and water-in-sand coatings on the market rely on special air spray tools for construction. This spraying method not only has relatively low construction efficiency, but may also affect the final effect of the coating due to uneven spraying. In the modern construction industry that pursues high efficiency, energy saving and environmental protection, this construction method obviously can no longer meet market demand.

[0005] Therefore, there is an urgent need to develop a new type of water-in-water artistic paint to meet the market demand for new, efficient and environmentally friendly building decoration materials. Summary of the invention

[0039] The above technical solution provided by the embodiment of the present invention has at least the following advantages compared with the prior art:

[0040] The embodiment of the present invention provides an airless spray textured water-in-water art paint with high efficiency and mildew resistance. The paint has the following characteristics: first, it should have a certain texture and can directly form a stone-like effect without the need for additional sand-containing textured paint; second, the construction process should be efficient and simple to reduce the construction difficulty and time cost; at the same time, the paint should have high efficiency and mildew resistance to ensure that the coating remains beautiful and healthy and environmentally friendly during long-term use; finally, in order to further improve the construction efficiency, the paint should be suitable for airless spray tools to achieve a fast and uniform spraying effect. Specifically:

[0041] 1) The present invention obtains a water-in-water artistic paint with a stone-like texture;

[0042] 2) The artistic coating provided by the present invention has the characteristics of high efficiency, convenient construction and low consumption;

[0043] 3) The artistic coating provided by the present invention has a long-term and efficient anti-mildew function;

[0044] 4) The artistic paint provided by the present invention can obtain various effects by using different spraying tools and air pressure, "one product with multiple effects":

[0045] How to obtain the water-in-water effect of stone imitation in the present invention, and at the same time have the characteristics of high efficiency, simplicity and low consumption in construction:

[0046] To obtain a good water-in-water imitation stone effect, it is necessary to spray out an obvious uneven surface structure to obtain texture. Therefore, it is necessary to reduce the deformation of the color dots during the entire spraying process, enhance the ability to resist deformation, and reduce the volume change of the paint film drying shrinkage to obtain an uneven surface structure and better texture. The following two points are mainly used to design color dots with better toughness. The first point is to use hydrophobic modified hydroxyethyl cellulose and hydroxyethyl cellulose. Choosing a suitable combination of lithium magnesium silicate and cellulose can obtain color dots with stronger toughness and increase its dosage, so that the reaction "gel" is more complete. The hydrophobic modified hydroxyethyl cellulose and lithium magnesium silicate form a "gel" and also associate with the emulsion, making the formed three-dimensional network structure more firm and complete, and enhancing the ability to resist pressure. The second point is to use wood fiber + high-content powder. Wood fiber is similar to the role of "rebar". High-content powder makes the color dots stronger, thus resisting the high pressure of airless spraying, so that the color dots have good integrity and low deformation during the spraying process. In addition, wood fiber plays a skeleton role in the film-forming process. At the same time, more powder synergistically fills the strength (similar to the role of "coarse aggregate") and increases the volume solid content, so that the volume change of the color dots after shrinkage during the drying process of the paint film is reduced, making the texture strong and meeting the demand for better texture with low consumption.

[0047] How the present invention achieves long-term and efficient mildew-proof function:

[0048] By designing a base paint with a high mildewproofing agent content, the particle size is controlled to be very small during granulation, so that it can be evenly present in the paint film as a minimal white color point of the base paint, and the paint film can play the role of a mildewproofing agent warehouse. A certain stacking density is required to release the mildewproofing agent in time to exert the mildewproofing function. Specifically, the emulsion content is high, the mildewproofing agent content is relatively high, and a "microcapsule" structure is formed after drying. The degree of encapsulation of the mildewproofing agent by the emulsion and powder can be used to control the ease and duration of the mildewproofing agent release, thereby achieving the effect of sustained release of the mildewproofing agent and obtaining long-term and efficient mildewproofing function.

[0049] How to achieve various effects with different spraying tools, "one product with multiple effects"

[0050] When using airless spraying, the principle is to extrude the material so that the material coming out of the nozzle is all water-in-water paint, so the substrate can be fully covered. When the discharge pressure is low, the color dots can resist the extrusion damage caused by the pressure through their own strength and toughness. At the same time, the force of contact with the substrate is small, which can well maintain its own uniform three-dimensional "rounded" shape, with small deformation, and obtain a better texture. Moreover, the color dots are about the same size as the paint can, maintaining consistent and clear color dots. When the air pressure is increased, the color dots that appear will be broken due to the high pressure and will be smaller when they come out of the nozzle. In addition, the force of contact with the substrate will also be greater, which will cause a slightly larger deformation, weaken the three-dimensional sense, and weaken the texture presented. When the product is diluted with water for construction, because the viscosity is reduced, the same unit discharge mass can be obtained at a lower air pressure, but the toughness of the color dots in the product remains unchanged, and the force of contact with the substrate is reduced, so the color dots are deformed less, and a more obvious three-dimensional sense or texture can be obtained. Therefore, customers can obtain various effects by changing the construction process, with a large operating space, and achieve "one product with multiple effects". BRIEF DESCRIPTION OF THE DRAWINGS

[0108] Test Case

[0109] This example tests the performance of the artistic coatings provided in the embodiments and comparative examples.

[0110] Test method:

[0111] 1) Viscosity: After the product is produced, observe the temperature and test the viscosity in time.

[0112] 2) Color penetration: spray a certain amount of water-in-water paint on a certain area of ​​blue substrate and observe whether the color of the substrate is clear.

[0113] 3) Storage stability: For heat storage stability, place it in a 50℃ oven for 30 days, observe the viscosity change, construction status and paint film condition before and after heat storage, and pass if there is no abnormality. For freeze-thaw stability, place it in a -7℃ constant temperature box, take it out after 18 hours and place it at room temperature, and place it in a -7℃ constant temperature and humidity box after 6 hours. After three cycles, stir it to make it flowable, observe the construction status and paint film condition before and after freeze-thaw, and pass if there is no abnormality.

[0114] 4) Color dot toughness, adjust the product viscosity to be consistent, use air spray, control the spray gun distance and air pressure, spray the same quality of water-in-water paint, and observe the color dot size and texture comparison after drying

Observe the board's performance in the first month, the second month, the third month, the fourth month, the fifth month, and the sixth month to see if there is mold growth.

[0116] The test results are shown in Table 7 below.

[0117] Table 7

[0118]

[0119] Compared with Example 1:

[0120] Example 2: The amount of wood fiber is higher, the physical cross-linking is more sufficient, and the pressure resistance is higher, so the deformation is smaller and the texture is stronger;

[0121] Comparative Example 1: The amount of protective glue used is insufficient, and the degree of "gelation" formed with cellulose is insufficient, resulting in a low density of the three-dimensional network structure, which makes the color point toughness poor;

[0122] Comparative Example 2: Wood fiber can form a macroscopic rigid three-dimensional network structure in the color dots, and obtain good resistance to pressure deformation. In Comparative Example 2, no wood fiber is added, resulting in poor toughness of the color dots;

[0123] Comparative Example 3: The emulsion content in the mildew-proof base paint is too high, and the mildew-proof agent is too densely wrapped, resulting in untimely release of the mildew-proof agent, resulting in the presence of spot mold;

[0124] Comparative Example 4: Only hydroxyethyl cellulose was used. The product had insufficient high shear resistance under high pressure, which made the colored dots easily broken. Although the overall antifungal agent content was consistent with that in Example 1, the antifungal performance was not as durable as that in Example 1 because the antifungal agent in Comparative Example 4 was more easily consumed and lost.

[0125] In addition, the effect diagram of an airless spray textured water-in-water art paint with high mildew resistance provided in Example 1 of the present invention is as follows: Figure 1 As shown, the effect of no color bleeding after 30 days of storage at room temperature is as follows Figure 2 As shown, the effect of no color bleeding after 30 days storage at 50℃ is as follows Figure 3 As shown, the state of the opened can after storage at 50℃ for 30 days is as follows Figure 4 shown.

[0126] The foregoing is merely a specific embodiment of the present invention, which enables those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features claimed herein.
