Abstract

The invention provides a coating construction method for an anti-bacteria self-cleaning wall. The method includes the following steps of processing a base layer, applying base paint, puttying, carrying out construction at a bottom layer, carrying out construction at a middle layer and constructing a face layer. Paint of the face layer comprises 40-50 parts of acrylic resin emulsion, 5-7 parts of titanium dioxide, 5-7 parts of lithopone, 7-10 parts of talcum powder, 2-4 parts of nanosilicon dioxide, 2-4 parts of nanometer titania, 1-2 parts of nano-zinc oxide, 0.1-1 part of stearic acid zinc salt, 0.1-0.3 part of citric acid, 0.05-0.15 part of rhenium oxide and 30-70 parts of water. The wall constructed in the method has certain sterilizing, anti-bacteria and self-cleaning functions, effectively reduces breeding of bacteria, viruses and the like on the wall, reduces spreading probability of pathogenic bacteria, has certain anti-fouling and self-cleaning functions and is long in cleaning cycle.

Description

technical field [0001] The invention relates to the technical field of coating construction, in particular to an antibacterial and self-cleaning wall surface coating construction method. Background technique [0002] During the use of the wall, it will inevitably absorb bacteria, dust and other dirt in the air, which not only causes surface pollution and even covers the original color, affecting its use effect, but more importantly, the bacteria on the wall The breeding of etc., especially public health places such as hospitals, is very easy to spread diseases, causing the infection of regional diseases. If the wall is cleaned, high-altitude operations are required when the wall is too high, which brings certain safety hazards to the staff. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an antibacterial self-cleaning wall coating construction method for the above deficiencies in the prior art. The wall surface ...
