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 If it is not suitable, it is very easy to cause unstable color, poor leveling, and insufficient adhesion after the plastic powder is sprayed 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 formula of an original white electrostatic powder raw material. The formula comprises 20kg of epoxy resin, 20kg of polyester resin, 14kg of titanium dioxide, 3kg of zinc oxide, 5kg of barium sulfate, 3kg of a leveling agent and 0.02kg of ultramarine. The formula of the original white 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 the original white 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 the plastic powder is sprayed on the metal surface. Therefore, it is a practical problem for people to adjust the formula of each electrostatic powder. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention pro...
