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.

The invention discloses a formula of a pearl white electrostatic powder raw material. The formula comprises 15.2kg of epoxy resin, 15.2kg of polyester resin, 7.2kg of titanium dioxide, 7.7kg of barium sulfate, 1.4kg of zinc oxide, 1.9kg of a leveling agent, 0.0072kg of Hansa yellow and 0.0029kg of pigment yellow. The formula of the pearl 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 pearl white 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 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 provides a pearl white e...
