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.

Abstract

The invention relates to a raw material formula for black-green electrostatic powder. The raw material formula comprises 10.8 kg of epoxy resin, 10.8 kg of polyester resin, 5.4 kg of barium sulfate, 1.2 kg of flatting agent, 0.06 kg of carbon black, 0.125 kg of iron red, 0.720 kg of ferrite yellow and 0.02 kg of medium chrome yellow. The raw material formula for black-brown 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 black-brown electrostatic powder raw material formula in electrostatic powder series products used for metal surface spray treatment. Background technique [0002] Originally used for metal surface rust prevention and decoration treatment, paint spraying was mostly used. At present, it has been used to spray metal surface with electrostatic powder. However, the raw materials and formulas used to make electrostatic powder are extremely difficult to grasp, because the composition of electrostatic powder raw materials Inappropriate, 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. Summary of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a black-brown electrostatic powder raw materia...
