Antibacterial latex paint and preparation method thereof

Abstract

The invention provides antibacterial latex paint. The latex paint is prepared from the following components, by weight: 100 parts of water, 8-13 parts of hydroxyethyl cellulose, 80-120 parts of modified acrylic emulsion, 25-40 parts of aluminum oxide modified nano titanium dioxide, 5-8 parts of a ZnOw nano antibacterial agent, 25-40 parts of nano silicon dioxide, 1-5 parts of a dispersing agent, 0.1-0.3 part of a defoaming agent and 0.5-3 parts of a coalescing agent. The antibacterial latex paint has the beneficial effects that (1), through the modification of the composite functional nano filler, the agglomeration of the nano antibacterial agent is effectively inhibited, and the antibacterial effect is improved; (2), due to the organic-fluorine-silicon-modified acrylic emulsion, the filmforming efficiency and quality are improved, and the stain resistance and weather resistance are improved; (3), an organic antibacterial agent is not used, so that the method is more environment-friendly; and (4), the emulsion paint prepared by the invention is simple to construct, smooth in paint surface, good in weather resistance and wide in application field.

Description

technical field [0001] The invention belongs to the technical field of latex paint, and in particular relates to an antibacterial latex paint and a preparation method thereof. Background technique [0002] Keeping the environment clean and pollution-free is a practical way to prevent bacteria and viruses from multiplying and preventing them from infecting humans. Using antibacterial materials is the simplest and most effective way to achieve a clean and pollution-free environment. [0003] Latex paint is a water-dispersible paint. It is based on synthetic resin emulsion, and the filler is refined by adding various additives after grinding and dispersing. Latex paint has many advantages that are different from traditional wall paints, such as easy to paint, fast drying, water-resistant paint film, and good scrub resistance. Latex paint is composed of emulsion, pigments, fillers, additives, fungicides and water. Some inferior architectural coatings, although they are called ...

AI Technical Summary

Problems solved by technology

Some inferior architectural coatings, although they are called latex paints, do not use the above-mentioned emulsions at all, but use chemical raw materials such as polyvinyl alcohol, polyvinyl formal, and even starch as binders. It is polyvinyl formal, which often contains a large amount of free formaldehyde due to the unqualified synthesis process, which will cause damage

In addition, during the storage process or after drying into a film, latex paint is polluted by microorganisms that exist everywhere, coupled with suitable temperature and humidity, it is easy to spoil the paint in the paint bucket, demulsification produces stench, and the paint film breeds. mold, blackened
