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 discloses a formula of a purple brown electrostatic powder raw material. The formula comprises 16.8kg of epoxy resin, 16.8kg of polyester resin, 11.2kg of barium sulfate, 2.2kg of a leveling agent, 0.096kg of carbon black and 0.45kg of bright red. The formula of the purple brown electrostatic powder raw material can ensure that the spray-mold surface color of molding powder is stable, and the surface is clean, smooth and bright and is strong in adhesive force.
Description
technical field [0001] The invention relates to a raw material formula of purple-brown 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 provide...
