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 of gray white electrostatic powder. The formula comprises 20kg of epoxy resin, 20kg of polyester resin, 12kg of titanium dioxide, 4kg of zinc oxide, 8kg of silicon micropowder, 1.2kg of flatting agent, 0.005kg of carbon black and 0.07kg of pigment yellow. The formula ensures that a plastic powder spraying surface is stable in color and luster, smooth and bright as well as strong in adhesive force.
Description
technical field [0001] The invention relates to a raw material formula of off-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 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...
