Abstract

An organosilicon-free easy-to-defoam guitar musical instrument nitro paint formula is prepared from 15kg of ethyl acetate, 15kg of n-butyl acetate, 5kg of isopropanol, 5kg of propylene glycol methyl ether acetate, 20kg of 1 / 16-second nitrocotton, 2kg of high-efficiency matting powder, 30kg of 70 pecent of an alkyd resin polymer, 5kg of non-matting wax slurry and 0.1kg of a bubble-breaking polymer solution (containing no organosilicon). A preparation method comprises the following steps: sequentially adding the ethyl acetate, the n-butyl acetate, the isopropanol, the propylene glycol methyl ether acetate and the 1 / 16-second nitrocotton, and continuously stirring for 30 minutes; then adding the 70 percent of alkyd resin polymer after completely dissolving the 1 / 16-second nitrocotton, and continuously stirring for 30 minutes; finally adding the high-efficiency matting powder, the non-matting wax slurry and the bubble-breaking polymer solution (containing no organosilicon), and stirring for 5 minutes.

Description

technical field [0001] The invention relates to the field of chemical paint manufacturing, in particular to a formula for improving the defoaming performance of nitro paint for guitar musical instruments without organic silicon and a manufacturing method thereof. Background technique [0002] The nitro lacquer for guitar instruments on the market generally has the problem of high viscosity and unsatisfactory defoaming effect. After stirring, a large number of air bubbles are prone to appear, and it needs to stand for a long time to defoam, which affects the construction time of nitro paint and also It is easy to affect the appearance of the guitar instrument. At the same time, nitro paints that are easy to defoam generally contain organosilicon compounds, which not only easily pollute the environment, but also affect the leveling performance of the coating when it is formed into a film, resulting in unsightly appearance of guitar instruments.
