Internal wall antibacterial emulsion paint and preparation method thereof

Abstract

The invention relates to internal wall antibacterial emulsion paint and a preparation method thereof. The internal wall antibacterial emulsion paint is characterized in that the paint comprises the following components in portion by weight: 25 to 40 portions of pure acrylic emulsion, 5 to 10 portions of dispersant, 10 to 20 portions of titanium dioxide powder, 0.1 to 0.2 portion of wetting agent, 20 to 40 portions of filler, 0.3 to 0.5 portion of defoaming agent, 3 to 6 portions of antibacterial agent, 0.5 to 1.0 portion of thickening agent, 10 to 25 portions of film forming assistant, 10 to 20 portions of anti-freezing agent, 0.3 to 0.5 portion of flatting agent, 0.3 to 0.5 portion of mildew-proof agent, 2 to 5 portions of colloid nano SiO2 30R12, 0.1 to 0.3 portion of bactericide, and 30 to 45 portions of tap water. The preparation method comprises the following steps: adding the tap water, the dispersant, the wetting agent, the defoaming agent, the anti-freezing agent, the titanium dioxide powder and the filler into a stirring container in turn, and stirring the mixture evenly; grinding the mixture to have the fineness of less than 35mu m in a grinding device; and adding the pure acrylic emulsion, the film forming assistant, the antibacterial agent, the colloid nano SiO2, the flatting agent, the thickening agent, the bactericide and the mildew-proof agent into the mixture, stirring the mixture evenly, and packing the mixture after inspection. The internal wall antibacterial emulsion paint and the preparation method thereof have the advantages that the paint film property of the pure acrylic emulsion with low voc is fully utilized, and simultaneously the introduced antibacterial agent and the functional assistant can keep good physiochemical performance of the paint film and have good environment-friendly performance and antibacterial performance at the same time.

Description

technical field [0001] The invention belongs to coatings, in particular to a novel interior wall antibacterial latex paint and a preparation method thereof. Background technique [0002] At present, the use of latex paint to decorate the interior walls of buildings has become a fashionable and commonly used method. Ordinary interior wall latex paint has the advantages of strong adhesion, good decoration and strong hiding power. However, it does not have antibacterial function, and cannot meet the occasions with higher requirements for environmental protection and antibacterial, such as hospitals, food workshops, and children's rooms. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a kind of interior wall antibacterial latex paint, which can ensure that the paint film formed by the latex paint has good antibacterial properties, mildew resistance, adhesion, hiding power and water and alkali...
