Problems solved by technology
[0002] Originally used for metal surface rust prevention and decoration treatment, paint spraying is mostly used. Now it has entered the use of electrostatic powder for metal surface spraying treatment, but the raw materials and formulas used to manufacture electrostatic powder are extremely difficult to grasp, because the electrostatic powder raw material composition It is very easy to cause unstable color, poor leveling, and insufficient adhesion after electrostatic powder spraying on the metal surface. Therefore, adjusting the formula of each electrostatic powder is a practical problem faced by people.

The invention relates to a raw material formula of matt gray electrostatic powder. The raw material formula comprises 30kg of epoxy resin, 2.5kg of matting agent, 7kg of barium sulfate, 3kg of titanium dioxide, 2kg of leveling agent, 1.5kg of hydrogenated castor oil, 0.07kg of carbon black, 0.03kg of iron oxide red and 0.045kg of medium chrome yellow. The raw material formula of the matt gray electrostatic powder can ensure that the molding powder spraying surface has stable color and luster, the surface is smooth and bright, and the adhesion is strong.
Description
technical field [0001] The invention relates to a raw material formula of matt gray electrostatic powder in a series of electrostatic powder products used for plastic spraying treatment on metal surfaces. Background technique [0002] Originally used for metal surface rust prevention and decoration treatment, paint spraying is mostly used. Now it has entered the use of electrostatic powder for metal surface spraying treatment, but the raw materials and formulas used to manufacture electrostatic powder are extremely difficult to grasp, because the electrostatic powder raw material composition If it is not suitable, it is very easy to cause unstable color, poor leveling, and insufficient adhesion after electrostatic powder spraying on the metal surface. Therefore, adjusting the formula of each electrostatic powder is a practical problem faced by people. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a...
