A kind of mildew-proof and antibacterial weather-resistant water-based interior wall paint and preparation method thereof

Abstract

The invention discloses a mildewproof antibacterial weather-resistant aqueous interior wall coating material. The mildewproof antibacterial weather-resistant aqueous interior wall coating material isprepared from the following ingredients in parts by weight: 18-35 parts of acrylate monomer, 3-6 parts of Eucalyptus urophyllax powder, 1-3 parts of nano montmorillonite, 1-2 parts of emulsifier, 0.8-1 part of initiator, 1-5 parts of white carbon black, 1-2 parts of film forming assistant, 0.5-1.5 parts of antifoamer, 0.5-1 part of thickener, 0.5-1 part of leveling agent and 20-30 parts of deionized water. The invention further discloses a preparation method for the aqueous interior wall coating material. The interior wall coating material disclosed by the invention is good in coating performance and excellent in stability and has good mildewproof and antibacterial performance, coatings are good in mechanical properties, and the preparation is simple.

Description

Technical field:

[0001] The invention relates to the application of building materials, in particular to a mildewproof and antibacterial weather-resistant water-based interior wall paint. Background technique:

[0002] Harmful substances in interior wall coatings mainly include volatile organic compounds (VOC), heavy metals and suspended particles, which together constitute indoor pollution sources and damage human health. Therefore, it is extremely important to carry out research on interior wall coatings, improve the pollution of interior wall coatings to the indoor environment, create a good living and working environment for people, and protect the health of the crowd. In recent years, a large number of scholars have participated in the research of interior wall coatings, improved various performances of interior wall coatings on the basis of the original, and developed some new coatings at the same time.
