Abstract

The invention discloses a formula and preparation method of easy-drying nitrolacquer for clarinet musical instruments. 1 / 16s nitrocellulose and an alkyd resin polymer are the main film-forming substances. Ethyl acetate, n-butyl acetate, isopropanol and propylene glycol methyl ether acetate are the main solvents for dissolving nitrocellulose. 2, 2-dimethylolbutanoic acid is the main additive to increase the drying rate of the paint film and can increase the drying rate of the paint during the film formation process.

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 a clarinet musical instrument nitro lacquer paint film and a manufacturing method thereof. Background technique [0002] Currently, nitro lacquers for clarinet instruments on the market generally have the problems of high viscosity and unsatisfactory drying effect of the paint film. After spraying, they need to stand for a long time to dry, which affects the construction time of nitro paints. At the same time, in the long drying process, it is also easily affected by the external environment and destroys the beauty of the clarinet instrument. Contents of the invention [0003] The invention solves the problem of slow drying of the nitro paint film of the existing clarinet musical instruments, and invents a formula for improving the drying rate of the paint film and a manufacturing method thereof. [0004] The technical sche...
