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 to spray metal surface. 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 relates to a raw material formula for red-white electrostatic powder. The raw material formula comprises 18.6 kg of epoxy resin, 18.6 kg of polyester resin, 10.8 kg of titanium dioxide, 9.6 kg of barium sulfate, 2.4 kg of flatting agent, 0.09 kg of ultramarine and 0.0027 kg of permanent violet. The raw material formula for red-white electrostatic powder has the advantages that a molding powder sprayed surface can be guaranteed of stable color and luster and is clean, smooth and bright, and the adhesive power is high.
Description
technical field [0001] The invention relates to a raw material formula of red-headed 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 to spray metal surface. 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 raw material formula of red-headed white electrostatic powder. The raw material formula of red-headed white electrostatic powder can ensure that the surface color of the plasti...
