Abstract

The invention relates to a hydrophobic moldproof low-VOC (volatile organic compound) environment-friendly latex paint which contains the following components in percentage by weight: 5-20% of water, 0.1-0.5% of dispersant, 0.2-0.8% of thickener, 0.05-0.3% of defoaming agent, 15-30% of pigment and filler, 30-50% of film-forming matter, 0.5-1.5% of other assistants, 0.1-1% of mold preventive and 1-6% of hydrophobing agent. The hydrophobic moldproof low-VOC environment-friendly latex paint provided by the invention has favorable moldproof and antibacterial effects and good stain resistance, scrub resistance and weather resistance, is high in hardness and adhesive force, non-toxic and harmless, has no after tack at a high temperature and can form a film at a low temperature, thus being a latex paint conforming to the characteristic of environment friendliness.

Description

technical field [0001] The invention relates to an environment-friendly latex paint, in particular to a hydrophobic, mildew-proof and low-VOC environment-friendly latex paint. Background technique [0002] At present, the consumption of latex paint in China is increasing year by year, but most latex paints have high VOC, which can not be underestimated for environmental pollution and has a great impact on human health. At the same time, the surface of the paint film of latex paint is easy to be uneven, easy to be polluted, and the effect of stain resistance and mildew resistance is not good. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a kind of environment-friendly latex paint with hydrophobicity, mildew resistance and low VOC. [0004] Technical solution: A hydrophobic, mildew-proof and low-VOC environmentally friendly latex paint, which contains the following ingredi...
