Embodiment Construction
[0011] 15 kg of ethyl acetate, 15 kg of n-butyl acetate, 5 kg of isopropanol, 5 kg of propylene glycol methyl ether acetate, 20 kg of 1 / 16 second nitrocellulose, 2 kg of high-efficiency matting powder, 70% alkyd resin polymer 30 kg, 5 kg of matt wax paste, 0.1 kg of foam-breaking polymer solution (without silicone). Add ethyl acetate, n-butyl acetate, isopropanol, propylene glycol methyl ether acetate, and 1 / 16 second nitrocellulose in sequence, and continue stirring for 30 minutes. After the nitrocellulose is completely dissolved, add 70% alkyd resin polymer, Continue to stir for 30 minutes, and finally add high-efficiency matting powder, matting wax slurry, and foam-breaking polymer solution (without silicone), and stir for 5 minutes.

The technical effect of the invention is that paint bubbles can rapidly burst by changing the surface tension of the paint bubbles because a formula and a preparation method are adopted, so that the purpose of defoaming can be achieved. The rapidity can be guaranteed in a paint construction process and construction will not be delayed because of waiting for defoaming. Meanwhile, the bad influenceof organosilicon can be eliminated in paint.
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 clarinet nitro paint without organic silicon and a manufacturing method thereof. Background technique [0002] Now the clarinet nitro paint on the market generally has the problem of high viscosity and unsatisfactory defoaming effect. After stirring, a large number of bubbles are prone to appear, and it needs to be left for a long time to defoam, which affects the construction time of the nitro paint, and is also easy Affects the aesthetics of the clarinet. 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 the unsightly appearance of the clarinet. Contents of the invention [0003] The invention solves the problem that the...
