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.
