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 for black-green electrostatic powder. The raw material formula comprises 21 kg of epoxy resin, 21 kg of polyester resin, 3.6 kg of titanium dioxide, 14.4 kg of barium sulfate, 3 kg of flatting agent, 1.4 kg of phthalocyanine blue, 0.54 kg of hansa yellow and 0.06 kg of carbon black. The raw material formula for black-green electrostatic powder has the advantages that a molding powder sprayed surface can be guaranteed of stable color and luster and is clean, smooth and bright, and the adhesive power is high.
Description
technical field [0001] The invention relates to a raw material formula of black and green 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 prov...
