Abstract

The invention discloses high-weather-resistance high-stain-resistance white paint for outdoor woodware and a preparation method of the paint. The high-weather-resistance high-stain-resistance white paint for the outdoor woodware comprises the following components in percentage by weight: 28-32% of water-based pure acrylic emulsion, 28-32% of water-based self-crosslinking acrylic emulsion, 22-27% of titanium dioxide pulp, 0.2-0.3% of a defoaming agent A, 2-3% of a film forming additive, 1.5-2% of wax emulsion, 0.3-0.5% of a light stabilizer, 0.5-1% of nanometer zinc oxide pulp, 0.1-0.15% of a first in-tank preservative, 0.2-0.4% of mildew-proof algaecide, 0.2-0.3% of a substrate wetting agent, 0.2-0.7% of a first thickening agent and 3.85-16.3% of deionized water or purified water. The high-weather-resistance high-stain-resistance white paint for the outdoor woodware is resistant to weather, stain and water, low in smell and VOC and excellent in environmental protection and safety comprehensive performances; the preparation method is simple in process and low in cost.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a preparation method of a highly weather-resistant and stain-resistant outdoor wood finish white finish. Background technique [0002] Compared with indoor water-based wood coatings, outdoor water-based wood coatings have to face harsh environments such as sun and rain, acid rain and dust, and large temperature changes. Outdoor wood itself is easily affected by external light, high temperature, humidity and The erosion of microorganisms leads to wood deformation, cracking and aging. Therefore, outdoor water-based wood coatings must meet the most basic performance requirements such as outdoor weather resistance, water resistance, flexibility and elasticity, mildew and algae resistance, stain resistance and air permeability. [0003] At present, the pure acrylic emulsion that is suitable for outdoor use needs to have a lower glass transition temperature Tg, resulting in a softer surface of...
