Abstract

The invention relates to the technical field of water-based wood paints, and provides a water-based electrostatic finishing paint, which comprises the following components in percentage by weight: 35-45 percent of first water-based emulsion, 25-35 percent of second water-based emulsion, 4-5 percent of coalescing agent, 0.5-0.7 percent of rheological agent, 0.2-0.3 percent of thixotropic agent, 0.1-13 percent of other auxiliaries and 5-20 percent of deionized water based on 100 percent of total weight of the water-based electrostatic finishing paint. The obtained water-based electrostatic finishing paint is suitable for electrostatic spraying, does not have a sagging phenomenon, has the characteristics of high drying speed, good after-tack resistance and good stacking resistance, can be effectively used for electrostatic spraying, is uniform in coating and relatively good in painting effect in the use process, improves the production efficiency and reduces the production cost.

Description

technical field [0001] The application belongs to the technical field of water-based wood paint, in particular to a water-based electrostatic topcoat and a preparation method thereof. Background technique [0002] Water-based wood paint has the characteristics of low VOC and environmental protection. Electrostatic spraying also has the advantages of good construction environment and working conditions, high paint utilization rate, flow operation, and high production efficiency. Therefore, water-based electrostatic spraying is favored by many manufacturers. In order to make the water-based wood lacquer suitable for electrostatic spraying, it is usually necessary to dilute the water-based wood lacquer to Iwata No. 2 cup for 30-40 seconds. However, under this viscosity, the electrostatic spraying of general products is easy to hang, and the paint effect is not good, and it cannot protect and decorate. The effect limits the application of water-based wood paint. Contents of th...
