Abstract

The invention discloses a leveling modified polyurethane wood lacquer formula and a manufacturing method thereof. The formula and the manufacturing method thereof disclosed by the invention have the technical effects that the solvent evaporation rate during paint volatilization can be relieved, so that production of benard cells during paint curing can be reduced. Therefore, the leveling propertyof the polyurethane wood lacquer is greatly improved, 'orange peel' is reduced, and attractive and elegant appearance of the product is ensured.

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 wood polyurethane paint and a manufacturing method thereof. Background technique [0002] The wood polyurethane paints currently on the market generally have problems of high viscosity and unsatisfactory leveling effect, which can easily lead to problems such as "orange peel" and protruding Bernard swirls that affect the final effect of wood product coatings and affect the appearance of wood. Contents of the invention [0003] The invention solves the problem of poor leveling of the existing wood 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 wood polyurethane coating and its manufacture method, comprise A and B two kinds of components: [...
