Styrene-acrylic antibacterial interior wall coating and preparation method thereof

Abstract

The invention provides a styrene-acrylic antibacterial interior wall coating and a preparation method thereof. The styrene-acrylic antibacterial interior wall coating is prepared from the raw materials of: in parts by weight, 20-40 parts of styrene-acrylic emulsion, 6-10 parts of nano titanium dioxide slurry, 4-6 parts of antibacterial nano titanium dioxide, 1-3 parts of ultrafine aluminum carbonate, 8-16 parts of calcined kaolin, 10-20 parts of titanium dioxide, 10-20 parts of ground calcium carbonate, 4-6 parts of talc powder, 1-2 parts of a dispersant, 0.2-0.5 part of a defoaming agent, 0.1-0.3 part of a wetting agent, 1.0-2.5 parts of a film forming assistant, 0.5-0.9 part of a thickener, 1-2 parts of an antifreezing agent, 0.1-0.2 part of a pH regulator and 12-20 parts of deionized water. The styrene-acrylic antibacterial interior wall coating not only has good low temperature stability, water resistance, alkali resistance, scrub resistance, weather resistance, dirt resistance andaging resistance, but also has bacteria resistance and bacteria inhibition, high decorativeness, breathing humidity regulation, environmental protection and other advantages.

Description

technical field [0001] The invention relates to an interior wall paint, in particular to a styrene-acrylic antibacterial interior wall paint and a preparation method thereof. Background technique [0002] Interior wall paint is latex paint for general decoration. Latex paint is an emulsion paint, which can be divided into two categories: polyvinyl acetate emulsion and acrylic emulsion according to different substrates. Latex paint uses water as the diluent. It is a paint that is easy to construct, safe, washable, and has good air permeability. It can be formulated according to different color schemes to produce different colors. At present, building decoration materials, especially the decoration materials for the interior walls of houses, mainly play the role of beautifying indoors and outdoors, making people feel comfortable and warm, and making houses stronger. The materials used are generally kaolin, silica lime powder, talcum powder, mica powder, titanium White powder...

AI Technical Summary

Problems solved by technology

Although building decoration materials can make the interior walls beautiful and tidy, thus making the living and living environment more comfortable, many existing building decoration materials tend to breed mold and insect eggs on the surface of the wall during use, especially in humid areas such as coastal areas. Mold can reproduce in large numbers under suitable conditions of 20-38°C and a relative humidity of about 85%, eroding the surface of buildings and destroying substrates. At the same time, the surface of building interior wall coatings is also the main breeding ground for fungi, bacteria, and insect eggs due to the large exposed area. Location

On the one hand, these molds, bacteria, fungi, and insect eggs destroy the beauty and flushability of the paint surface, and on the other hand, they seriously affect people's health
