Abstract

The invention discloses a formula and preparation method of leveling-modified nitrolacquer for a Guqin instrument. The nitrolacquer comprises, by weight, 10 to 15% of ethyl acetate, 10 to 15% of n-butyl acetate, 5 to 10% of isopropanol, 3 to 5% of propylene glycol methyl ether acetate, 20 to 25% of 1 / 16s nitrocellulose, 1 to 5% of high-efficiency matting powder, 20 to 30% of 70% alkyd resin polymer, 1 to 5% of matting-free wax slurry and 0.1 to 1% of polyether modified polydimethylsiloxane.

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 nitro paint for guqin musical instruments and a manufacturing method thereof. Background technique [0002] Nitro-based lacquers for guqin instruments 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 guqin musical instrument coatings and affect the quality of guqin musical instruments. beautiful. Contents of the invention [0003] The invention solves the problem of poor leveling of the existing guqin musical instrument nitro paint, 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 and its manufacture method that solves the poor leveling o...
