Green, environmentally-friendly, waterproof, antibacterial and mildew-resistant decoration coating and preparation method thereof

Abstract

The invention discloses a green, environmentally-friendly, waterproof, antibacterial and mildew-resistant decoration coating and a preparation method thereof. The decoration coating comprises, by weight, 30-40 parts of polyamine resin, 15-25 parts of butyl acrylate, 10-16 parts of polyvinyl alcohol, 4-8 parts of a modified nano-additive, 8-10 parts of ore powder, 2-4 parts of a mildew inhibitor, 1-3 parts of a botanical bactericide, 4-6 parts of hollow ceramic microbeads, 2-4 parts of reinforced fibers, 1-3 parts of titanium dioxide, 5-7 parts of a flame retardant additive, 6-9 parts of a processing enhancing additive and 18-24 parts of deionized water. The coating has the advantages of excellent hydrophobic and impermeable performances, good film forming performance, smooth and fine surface, certain sterilizing, bacterium-killing and mildew-resisting effects, realization of greenness and environmental protection due to the use of the botanical antibacterial and mildew-resistant additives, safe and reliable raw material components, no toxic or harmful volatile substances, low cost, simple process, high practical values and good application prospect.

Description

technical field [0001] The invention relates to the technical field of environment-friendly coatings, in particular to a green, environment-friendly, waterproof, bactericidal and mildew-resistant decorative coating and a preparation method thereof. Background technique [0002] In recent years, due to the increasing amount of coatings used and the wider range of applications, its importance has gradually been recognized, and related basic research on applications has also been developed, but it is still difficult to meet the higher needs of coatings development. With the development of science and technology Progress, coatings, a material that plays an important role in the development of the entire national economy and the improvement of people's lives, will inevitably have new and greater development in China, and relevant research will gradually increase.

AI Technical Summary

Problems solved by technology

[0003] With the rapid development of the paint industry, various environmentally friendly paints emerge in an endless stream, most of which are relatively expensive.

[0004] Environmentally friendly paint, especially the environmentally friendly paint on the wall, is usually prone to the following problems during use: mildew or oxidation is prone to occur on the wall, causing the paint to fall off, especially during the rainy season in the south, when the air is humid, it is more likely to appear The phenomenon of mildew on the wall and poor water resistance have brought a lot of inconvenience to consumers; most of the existing paint products contain certain harmful substances such as formaldehyde and volatile organic compounds, which usually emit unpleasant odors for a long time Odor, poor environmental performance

Although the products of the existing paint manufacturers can meet the limit standards for harmful substances stipulated in the national standards, they have not clearly stated that they do not contain certain harmful substances. The harmful substances in the existing paints not only cause harm to the human body, but also polluted environment

Existing environmentally friendly coatings, whether water-based or solvent-based, are mixed with anti-mildew agents in liquid paints. However, most of these agents mixed into paints are pesticides, and sometimes they are also used Organic mercury-based or arsenic-based compounds, so the paint is more or less toxic. Although the effect is good, the ubiquitous safety problems need to be solved

[0005] On the other hand, the level of research and development of environmental protection coatings by coating manufacturers is also constantly improving. However, the existing environmental protection coatings are not very perfect. For example, only the index of volatile matter is reduced to make it meet the standards

Although the development trend of the coatings industry is to achieve zero-VOC, odorless and healthy coatings, due to technical constraints and other factors, there are almost no truly zero-VOC environmentally friendly coatings on the market. Some harmful substances (such as formaldehyde, benzene, etc.) Heavy metals, etc.) will seriously affect people's living environment, and induce many chronic diseases, causing people's life and health to be threatened
