Abstract

The invention discloses a formula and preparation method of easy-drying polyurethane paint for Guqin musical instruments. Hydroxy polyacrylic resin, an isocyanate adduct, polyketone resin, 1, 6-hexamethylene diisocyanate and a matt trimer curing agent are the main film-forming substances of the paint and react with each other to form a film through crosslinking. Ethyl acetate, n-butyl acetate andcyclohexanone are the main solvents for dissolving the resin. 1 / 16s nitrocellulose is used to adjust the viscosity of the paint and is easy to construct. Matting-free wax slurry improves the feeling,fineness and scratch resistance. High-efficiency matting powder is used to adjust the luminosity of the paint and reduce light pollution. Dibutyltin dilaurate is a main additive to improve the dryingrate of the paint film and can improve the drying rate of the paint during the film formation process. The components are reasonably combined and a solvent evaporation rate is reasonable so that the excellent film forming properties are obtained. The easy-drying polyurethane paint has good polyurethane paint.

Description

technical field [0001] The invention relates to the field of chemical paint manufacturing, in particular to a formula for improving the drying rate of polyurethane paint film of guqin musical instruments and a manufacturing method thereof. Background technique [0002] The polyurethane paints for guqin musical instruments on the market generally have the problems of high viscosity and unsatisfactory drying effect of the paint film. After spraying, they need to be left for a long time to dry, which affects the construction time of polyurethane coatings. At the same time, in the long drying process, it is also easily affected by the external environment and destroys the beauty of the Guqin musical instrument. Contents of the invention [0003] The invention solves the problem of slow drying of the polyurethane paint film of the existing guqin musical instrument, and invents a formula for improving the drying rate of the paint film and a manufacturing method thereof.
