Problems solved by technology

[0003] However, traditional latex paint does not have antibacterial effect. In hospitals, children's rooms are prone to bacteria adsorption on the wall, and people who accidentally touch the wall will easily be contaminated with bacteria, which will cause harm to the body.

Abstract

The invention discloses an antibacterial emulsion paint, which is mainly prepared from the following raw materials in parts by weight: 20 to 25 parts of a basic material, 1.5 to 2 parts of a coalescing agent, 0.6 to 0.8 part of a dispersant, 0.4 to 0.5 part of a defoaming agent, 0.1 to 0.5 part of a leveling agent, 1 to 1.5 parts of organic bentonite, 10 to 15 parts of a filler, 0.2 to 0.5 part ofan antibacterial agent, 10 to 15 parts of a pigment, 22 to 30 parts of water and 0.4 to 0.6 part of hydroxyethyl cellulose. The emulsion paint disclosed by the invention has the characteristics of noscaling, high glossiness, high weather resistance, nontoxicity, high leveling property and easiness in construction, is anti-scouring, nontoxic and harmless and smells refreshing. The emulsion paintdisclosed by the invention is stably combined with the wall body and is relatively high in construction performance and relatively good in antibacterial and bacteria-inhibiting effect; furthermore, asterilization material is harmless to a human body and cannot cause environmental pollution.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an antibacterial latex paint. Background technique [0002] Latex paint is a common name for latex paint. It was born in the middle and late seventies of the 20th century. It is a large class of synthetic resin emulsion paint represented by acrylate copolymer emulsion. Latex paint is a water-dispersible paint, which is based on synthetic resin emulsion, and the filler is refined by adding various additives after grinding and dispersing. Latex paint has many advantages that are different from traditional wall paints, such as easy to paint, fast drying, water-resistant paint film, and good scrub resistance. In my country, it is customary for people to use synthetic resin emulsion as the base material, use water as the dispersion medium, add pigments, fillers (also known as body pigments) and additives, and the paint made through a certain process is called latex paint, ...
