Description

technical field

[0001] The invention relates to a raw material formula of purple-brown 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 provide...

Examples

Embodiment approach 1

[0008] Purple-brown electrostatic powder raw material formula, epoxy resin 16.8 kg, polyester resin 16.8 kg, barium sulfate 11.2 kg, leveling agent 2.2 kg, carbon black 0.096 kg, scarlet 0.45 kg.

[0009] Put the raw materials in the above ratio into a mixer for full mixing, then melt the mixed raw materials in a high-temperature extruder, extrude and cool them into flakes, then crush the raw flakes and sieve them into ultra-fine purple Brown electrostatic powder.
