Abstract

The invention belongs to the technical field of aqueous coating material preparation, and particularly relates to a quick-drying type aqueous acrylic container marking paint and a preparation method thereof, wherein the quick-drying type aqueous acrylic container marking paint comprises, by weight, 18-22 parts of water, 0.05-0.15 part of a bactericide, 0.05-0.15 part of an anti-settling agent, 0.1-0.3 part of a pH value regulator, 0.2-0.4 part of an antifoaming agent, 0.2-0.4 part of a dispersing agent, 30-34 parts of an acrylic resin, 1.5-2 parts of a film forming aid, 35-45 parts of titaniumdioxide, and 0.3-0.5 part of a wetting leveling agent.

Description

technical field [0001] The invention belongs to the technical field of water-based paint preparation, in particular to a quick-drying water-based acrylic container box standard paint and a preparation method thereof. Background technique [0002] Water-based acrylic coatings are widely used in the fields of interior and exterior walls of buildings, steel structures, petrochemicals, construction machinery, containers, etc. But most of the construction has no baking conditions. Therefore, water-based acrylic paints generally dry naturally at room temperature. Then the drying speed of acrylic paint will directly affect the painting efficiency and construction progress. At the same time, when the temperature is lower and the humidity is higher, the slower the drying speed, the more the performance of the paint film will be affected, and the protective effect of the paint will be weakened. [0003] Container box standard paint is still used in the market at present. Solvent-ba...
