Problems solved by technology

For example, the invention patent with application number 00125490.1 uses styrene-acrylic emulsion as the base material, adds additives and fillers of ordinary paints, and then adds nano-antibacterial powder and nano-silicon-based oxides to prepare interior wall coatings. The prepared coatings have better performance than Ordinary coatings have been improved, but the process mentioned in this patent cannot guarantee the full dispersion of nano-components, and does not give full play to the due effect of nano-components

Abstract

The invention discloses an interior wall paint which comprises the following components in percentage by mass: 2-8% of nano silicon oxide antimicrobial agent, 30-40% of styrene-acrylate copolymer emulsion, 1-5% of crystalline anion additive, 15-20% of titanium white pigment, 15-20% of filler, 1-2% of thickener, 1-2% of wetting agent, 0.3-1% of defoaming agent and the balance of deionized water. All the performance indexes of the interior wall paint are greatly superior to national standards for high-class products, the contents of harmful substances are far lower than the limits in national standards, and therefore, the interior wall paint has the advantages of high performance, multiple functions and environmental protection.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an antibacterial interior wall coating. Background technique [0002] Interior wall coatings are an important part of building decoration materials. There are many manufacturers and many brands of products, but most of them still have problems such as strong coating cloth, weak adhesion, easy peeling off of the coating, poor scrub resistance and staining. Poor pollution, harmful substances greatly exceed the national limit and other deficiencies. To provide the performance and quality of interior wall coatings, many people have done exploratory work, and some people use the method of adding nanometer components to improve the quality of interior wall coatings. For example, the invention patent with application number 00125490.1 uses styrene-acrylic emulsion as the base material, adds additives and fillers of ordinary paints, and then adds nano-antibacterial powder and nano-silicon-based ...
