High-efficiency environment-friendly antibacterial mould-proof inorganic composite nano paint and preparation method thereof

Abstract

The invention relates to a paint technology, an environment-friendly technology and an antibacterial mould-proof technology, in particular to high-efficiency environment-friendly antibacterial mould-proof inorganic composite nano paint and a preparation method thereof. The high-efficiency environment-friendly antibacterial mould-proof inorganic composite nano paint comprises the following components in percentage by weight: 0.5 to 5 percent of wetting dispersant, 0.01 to 20 percent of inorganic composite nano antibacterial agent concentrated pulp, 0.5 to 10 percent of hydrophobing agent, 0.5 to 10 percent of anionic powder, 0.5 to 8 percent of film-forming aid, 0.1 to 2 percent of anti-settling agent, 0.8 to 10 percent of antifreezing agent, 0.1 to 3 percent of defoaming agent, 4 to 30 percent of pigment, 0 to 30 percent of filler, 15 to 45 percent of emulsion, 0.1 to 4 percent of thickening agent, 0.1 to 3 percent of flatting agent, 0 to 3 percent of pH regulator and 0.5 to 45 percent of water. The high-efficiency environment-friendly antibacterial mould-proof inorganic composite nano paint is mainly prepared by adding the inorganic composite nano antibacterial agent into the basic materials, so that the paint has the coating characteristic of high performance, is low is cost, and has a function of purifying air, can eliminate harmful gas volatile organic compounds (VOC), formaldehyde and the like and also has a durable and high-efficiency antibacterial mould-proof function, so that the sterilizing rate within 6 hours reaches 100 percent and the mould-proof grade reaches the first grade. By the high-efficiency environment-friendly antibacterial mould-proof inorganic composite nano paint and the preparation method thereof, self-cleaning performance, hydrophobicity, scrubbing resistance, dirt resistance and weather resistance of the coating are improved; and the high-efficiency and durable antibacterial and mould-proof effect is achieved.

Description

technical field [0001] The invention relates to coating technology, environmental protection technology and antibacterial and anti-mildew technology, in particular to a high-efficiency environmental-friendly anti-bacterial and anti-mildew inorganic composite nano coating and a preparation method thereof. Background technique [0002] Latex paint is a kind of water-based paint, which contains very low organic volatile matter, meets the requirements of environmental protection, and belongs to "green paint". It has been greatly developed since the latex paint was produced, and people continue to find ways to improve the performance of latex paint from different aspects. The emergence of nano-materials has brought opportunities for the improvement of the performance of latex paints. For example, the Chinese invention patent CN1277234A discloses an architectural coating containing 0.5-1.5% silicon-based oxides, which improves the suspension, bonding strength, and aging resistance...

AI Technical Summary

Problems solved by technology

[0004] Inorganic composite nano-antibacterial coatings have the advantages of being safe and non-toxic to the human body, strong antibacterial and anti-mildew ability, wide antibacterial range, small odor, light appearance color, good thermal stability, washable, long storage period, cheap price, and extensive sources. Nanoparticles have a large specific surface area, are prone to agglomeration, and are difficult to effectively disperse in the solution. If they are not well dispersed, they will lose their due role in the coating. application key
