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.

Abstract

The invention relates to a high-gloss black electrostatic powder material formula which comprises 26 kilograms of epoxy resin, 26 kilograms of polyester resin, 10 kilograms of barium sulfate, 2 kilograms of calcium carbonate, 2.8 kilograms of leveling agent and 0.5 kilogram of carbon black. The high-gloss black electrostatic powder material formula can ensure stable color of a plastic powder coated surface, smoothness and brightness of the surface and high adhesive force.

Description

technical field [0001] The invention relates to a raw material formula of a high-gloss black electrostatic powder in a series of electrostatic powder products used for plastic spraying treatment on metal surfaces. Background technique [0002] Originally used for anti-rust and decorative treatment of metal surfaces, paint spraying is mostly used. Now it has entered the process of spraying metal surfaces with electrostatic powder, but the raw materials and formulas used to manufacture electrostatic powder are extremely difficult to grasp, because the raw materials of electrostatic powder 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 high...
