Abstract

The invention relates to a formula and preparation method of leveling-modified polyurethane paint for aluminum products. Through reduction of a solvent evaporation rate in paint volatilization, Bernadette vortexes are reduced in paint curing, the leveling effects of the polyurethane paint for aluminum products is greatly improved, orange peel phenomenon is reduced and the beauty of the product isguaranteed.

Description

technical field [0001] The invention relates to the field of chemical paint manufacturing, in particular to a formula for improving the leveling performance of aluminum ware polyurethane paint and a manufacturing method thereof. Background technique [0002] The aluminum polyurethane paints on the market now generally have the problems of high viscosity and unsatisfactory leveling effect, which can easily lead to problems such as "orange peel" and Bernard swirl protrusion that affect the final effect of aluminum product coatings and affect the appearance of aluminum products. . Contents of the invention [0003] The invention solves the problem of poor leveling of the existing aluminum ware polyurethane coating, and invents a formula improved by using a leveling agent and a manufacturing method thereof. [0004] The technical scheme of the present invention is, a kind of formula that solves the poor leveling of polyurethane paint on aluminum ware and its manufacture metho...
