High-solid transparent paint and preparation method thereof

[0037] Example 1

[0038] A high-solid transparent paint, which includes the following weight percentages of raw materials: acrylic resin 50%, amino resin 25%, epoxy resin 5%, pigment 1%, polymer phosphate 2%, leveling agent 1%, n-butyl Alcohol 16%.

[0039] The preparation method of high-solid transparent paint includes the following steps:

[0040] (1) After mixing the pigments evenly, place them in a horizontal grinder for grinding. The grinding air pressure is 0.05MPa, the grinding temperature is 30°C, and the grinding time is 10 hours per 500Kg. At the same time, the cavity of the grinder is cooled by circulating water;

[0041] (2) Add acrylic resin, amino resin, epoxy resin, polymerized phosphate ester, leveling agent, thinner for tack adjustment, and the pigment ground in step (1) into the high shear dispersing machine in sequence. Adjust the speed of the shearing disperser to 1200r / min, stirring for 20min at room temperature, then adjust the speed of the high-shearing dispers
