Abstract

The invention provides a preparation method of a water-based laser alumite paint with good temperature resistance. The paint comprises: 20-40% of a waterborne acrylic emulsion, 15-30% of a waterbornepolyurethane emulsion, 10-30% of a waterborne polyester emulsion, 10-30% of deionized water, 10-30% of ethanol, 0.01-0.1% of a defoamer, 0.1-1% of a wetting leveling agent and 0.05-0.1% of a mold pressing additive. The water-based alumite color layer paint disclosed by the invention is water-based, environment-friendly, low in cost, good in temperature resistance and good in mould pressing effect.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based anodized aluminum coating with good laser temperature resistance and a preparation method thereof. Background technique [0002] Anodized aluminum laser products are rich in color and have a strong metallic luster, and are widely used in the packaging industry. Currently, anodized aluminum laser products are mainly oil-based, because water-based laser products are easy to crack, stick to the plate, and have low temperature resistance, which is difficult to meet the needs of hot stamping. Contents of the invention [0003] Aiming at the molding performance of the water-based color coating, the temperature resistance is difficult to meet the performance requirements of the bronzing industry. The water-based color coating of the present invention has good film pressure and temperature resistance, and is a single component without high temperature curing and reduces ...
