Abstract

The invention discloses a self-cleaning nanometer composite environmental protection latex paint and preparing method, which comprises the following parts: 0.5-5% wetting disperser, 0.5-50% nanometer concentrated slurry, 0.5-10% hydrophobic agent, 0.5-10% anion powder, 0.5-8% filming adjuvant, 0.1-2% anti-settling agent, 0.8-10% antifreeze agent, 0.1-3% defoamer, 4-30% dye, 0-30% filler, 15-45% emulsion, 0.1-4% thickener, 0.1-3% levelling agent, 0-3% pH adjuster, 0-4% microbe eliminating agent and 0.5-45% water. The preparing method comprises the following steps: 1) placing water in the container with high-speed disperser; adding microbe eliminating agent, nanometer condensing slurry, hydrophobic agent, anion powder; blending evenly; adding dye and filler; dispersing until finesse reaches 20-60um; 2) adding emulsion, pH value adjuster, thickener and leveling agent continuously.

Description

technical field [0001] The invention relates to paint technology and environmental protection technology, in particular to a self-cleaning nano-composite environment-friendly latex paint and a preparation method thereof. Background technique [0002] Latex paint is a kind of water-based paint, which contains very low organic volatile matter, meets the requirements of environmental protection, and belongs to "green paint". It has been greatly developed since the latex paint was produced, and people continue to find ways to improve the performance of latex paint from different aspects. The emergence of nanomaterials has brought opportunities for the improvement of the performance of latex paints. For example, Chinese invention patent CN1277234A discloses a kind of architectural paint containing 0.5-1.5% silicon-based oxide. Improve the suspension, bonding strength, aging resistance and pollution resistance of the coating. Chinese invention patent CN1287145A reports a nano-p...
