Description

Technical Field

[0001] The present application relates to the field of coatings, and more specifically, to a highly wear-resistant interior wall coating and a preparation method thereof. Background Art

[0002] With the improvement of people's living standards, the requirements for interior wall coatings are not limited to the decorative effects of conventional latex paints with a single color. Art coatings have emerged as the times require. The luster, texture, and texture pursued by art coatings can endow the wall with rich and colorful decorative effects.

[0003] Moreover, when decorating and moving into a new home, people increasingly emphasize quick and healthy occupancy. Currently, the materials used in interior decoration still contain or are accompanied by some harmful substances more or less, especially pollution sources represented by formaldehyde. Therefore, people also have higher requirements for the functionality of coatings themselves, such as formaldehyde removal, scrub resistance, stain resistance, antibacterial, antiviral, and mildew resistance, low VOC, etc. In addition, currently, conventional colorful interior wall coatings hope to achieve the artistic effect of a matte flannel texture. However, without using a topcoat, although the wear resistance of the coating can meet the standard, it is still difficult to reach the level of using a topcoat. Using a topcoat will affect the texture, luster, and feel of the colorful interior wall coating. At the same time, the additional topcoat process will also increase the construction and usage costs.

[0004] Therefore, it has become an urgent task to provide a highly wear-resistant interior wall coating with high film hardness, scrub resistance, no need for a topcoat, excellent artistic decoration effect, green environmental protection, and a preparation method thereof for formaldehyde removal, antibacterial, and antiviral. Summary of the Invention

[0005] In view of the current consumers' advanced requirements for the artistic decoration effect of coatings and issues such as formaldehyde removal, antibacterial, antiviral, stain resistance, scrub resistance, and no need for a topcoat, the present application provides a highly wear-resistant interior wall coating and a preparation method thereof.

[0006] In the first aspect, the present application provides a highly wear-resistant interior wall coating, adopting the following technical solution:

[0007] A highly wear-resistant interior wall coating is made of materials including a granulation protective colloid, a color-matching base paint, and a continuous phase emulsion; the raw materials of the continuous phase emulsion include the following components in parts by weight:

[0008] 25 - 65 parts of water, 0.2 - 0.5 part of a mildew and bactericide, 0.5 - 1.5 parts of an antifreeze, 0.01 - 0.15 part of an antifoaming agent, 35 - 65 parts of a silicone-acrylic emulsion, 1 - 3 parts of a film-forming aid, 0.1 - 0.5 part of a pH regulator, 0 - 1 part of a thickener, 0 - 5 parts of a titanium sol, 0 - 5 parts of a zirconium sol; wherein, the particle size of the titanium sol is 15 - 25 nm, and the particle size of the zirconium sol is 20 - 35 nm.

[0009] By adopting the above technical solutions, the present application uses zirconia sol - titania sol as the key material, which can improve the thermal stability, abrasion resistance, rigidity, mechanical properties and other properties of the coating. At the same time, titania sol is the key material for removing formaldehyde, antibacterial and antiviral. As a photocatalyst material, titania sol enters the excited state under the excitation of light, making the adsorbed O2 and H2O on the surface generate highly reactive hydroxyl radicals and superoxide ion radicals. When free formaldehyde molecules and bacteria in the air come into contact with the surface, harmful substances will be decomposed into water and carbon dioxide, achieving the effect of removing formaldehyde, antibacterial and antiviral. However, during the research process, the researchers found that the addition of the composite sol is likely to cause deterioration of the paint film. Therefore, the present application uses titania sol and zirconia sol with specified content and particle size. After the continuous - phase emulsion formed by them is added to the coating, it can well improve the abrasion resistance, rigidity, mechanical properties and other properties of the coating, without the need for a topcoat, and also improves the problem of paint film deterioration. Moreover, the preparation process is simple and suitable for popularization and application.

[0011] Optionally, the preparation method of the zirconia sol includes the following steps: adding a mixed solution of absolute ethanol and deionized water to Zr0Cl2·8H20, then adding H202, stirring and reacting, dropping ammonia water into the solution and stirring, gradually forming a transparent sol, aging this sol at room temperature for 48 - 72 h to obtain a wet gel, drying it at 80 - 85 °C and then calcining it at 1020 - 1050 °C for 120 - 150 min, and configuring it into a 20% aqueous dispersion to obtain the zirconia sol.

[0012] Optionally, the granulation protective colloid includes the following components by weight: 3 - 10 parts of protective colloid powder, 75 - 97 parts of water, 0 - 1 part of thickener, and 0.2 - 0.5 part of mildew and bactericide.

[0014] Optionally, the base paint protective colloid comprises the following components by weight: 5-15 parts of protective colloid powder, 75-95 parts of water, and 0.2-0.5 part of mildew and bactericide.

[0015] Optionally, the mass ratio of the granulation protective colloid to the tinting base paint is 1:1.5-3.5.

[0016] Optionally, the total amount of the granulation protective colloid and the tinting base paint and the mass ratio of the continuous phase emulsion is 3-5:1.

[0017] In a second aspect, the present application provides a method for preparing a highly wear-resistant interior wall paint, adopting the following technical solution:

[0018] A method for preparing a highly wear-resistant interior wall paint, comprising the following steps:

[0019] Add the granulation protective colloid to a blender and stir, then add the tinting base paint to the blender. After the color dots are uniform, increase the rotation speed until the color dots reach the target size, thereby obtaining the dispersed phase;

[0020] Slowly add the continuous phase emulsion to the above-mentioned dispersed phase and stir evenly to obtain the highly wear-resistant formaldehyde-removing, antibacterial and antiviral multi-color interior wall art paint.

[0021] In summary, the present application has the following beneficial effects:

[0022] 1. The present application uses zirconia sol-titania sol as the key material, which can improve the thermal stability, wear resistance, rigidity, mechanical properties and other properties of the paint, and the titania sol can also help the paint achieve the effects of formaldehyde removal, antibacterial and antiviral.

[0023] 2. Regarding the problem that the introduction of titania sol and zirconia sol is likely to cause film deterioration, the present application stipulates the performance and dosage of titania sol and zirconia sol, directly studies the sol itself, and utilizes the optimization of the sol to finally obtain very excellent effects. It can not only improve the wear resistance, rigidity, mechanical properties and other properties of the paint well, but also improve the film deterioration problem. The present application bypasses the conventional idea in this field of improving the paint performance by adding other components and performing complex modifications, focuses on the sol itself, and not only the final paint has very excellent performance, but also the preparation process is simple and suitable for popularization and application.

[0097]

[0098] According to the test results in Table 3-5, the coating of this application has good formaldehyde removal, antibacterial and antiviral properties. Additionally, further analysis of the properties in Table 1 reveals that Examples 1-7 have excellent wear resistance, not only higher than the standard value, but also not much different from that of Comparative Example 2 using a topcoat, and among them, Example 4 has the most excellent performance. Through the performance analysis of Comparative Example 1, it can be known that the excellent wear resistance of this application is obtained by adding zirconium sol and titanium sol.

[0099] However, further analysis of the properties of Comparative Examples 3-5 shows that although the addition of zirconium sol and titanium sol can well improve the wear resistance of the coating, excessive addition will cause the paint film to crack, resulting in the cracking of the paint film. At the same time, Comparative Examples 6-8 also illustrate the necessity of the particle size limitation of silica sol and zirconium sol in this application. Since Comparative Examples 6-8 do not use the optimized sol of this application, the final paint films all showed cracking phenomena, which once again shows that when the particle size of titanium sol is 15-25 nm and the particle size of zirconium sol is 20-35 nm, titanium sol and zirconium sol can play a good role in improving the wear resistance of the coating system of this application and will not cause the deterioration of the paint film.

[0100] In summary, this application can well improve the wear resistance, rigidity, mechanical properties and other properties of the coating, does not require a topcoat, also improves the problem of paint film deterioration, and has a simple preparation process suitable for popularization and application.

[0101] This specific embodiment is only an interpretation of this application and does not limit this application. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of this application, it is protected by the patent law.
