Antibacterial and mould-proof aqueous latex paint for inner wall of building and preparation method thereof

Abstract

The invention relates to the technical field of coatings and mainly relates to an antibacterial and mould-proof aqueous latex paint for an inner wall of a building and a preparation method thereof. The antibacterial and mould-proof aqueous latex paint for the inner wall of the building disclosed by the invention is composed of the following raw materials in parts by weight: 25-45 parts of acrylicemulsion, 0.2-1 part of aqueous wetting dispersant, 0.25-2.8 parts of hydroxyethyl cellulose, 0.1-1 part of multifunctional auxiliary agent, 0.06-0.9 part of organic silicon defoamer, 16-23 parts of titanium dioxide, 2-18 parts of nano-kaolin, 0.5-5 parts of mugwort extract, 0.1-2 parts of sabina oil, 0.1-2 parts of tannin, 0.1-1 part of coalescing agent and 20-40 parts of water. The aqueous latexpaint prepared by the invention has antibacterial and mould-proof capabilities; the contained antibacterial and anti-mildew agents are composed of multiple natural extracts so that the coating does not damage an environment and a human body during a usage process.

Description

technical field [0001] The invention relates to the technical field of coatings, and mainly relates to an antibacterial and mildew-proof water-based latex paint for building interior walls and a preparation method thereof. Background technique [0002] Water-based latex paint is a common paint used to decorate the walls of houses. Since water-based latex paint is a paint with water as the dispersion medium and rich in various functional additives, it is safer and more environmentally friendly than oil-based paint and water-based latex paint, and has been favored by people in recent years. However, water-based latex paint contains polymer emulsions, defoamers, thickeners and other organic substances that are conducive to the growth and reproduction of microorganisms, and the higher humidity of water-based latex paint is more likely to breed bacteria and mold. Therefore, in the production, storage and use of water-based latex paint, the problem of large-scale reproduction of ...

AI Technical Summary

Problems solved by technology

In the second way, the process of R&D, preparation and purification of raw materials with antibacterial and antifungal effects is very long and complicated

Organic antibacterial and antifungal agents have strong anti-discoloration ability, but they have disadvantages such as poor heat resistance, easy decomposition, and short effective time; inorganic antibacterial and antifungal agents mostly use the antibacterial and antifungal abilities of silver, copper, zinc and other metals to absorb these metal ions Loaded into inorganic porous materials as antibacterial and antifungal agents

This kind of inorganic antibacterial and antifungal agent has good antibacterial and antifungal effects, but the preparation cost is high and the loading process is relatively complicated, and the anti-discoloration ability is not good.
