Problems solved by technology

This method is prone to safety accidents such as combustion and explosion during the production process, and the metal powder coating produced is unevenly dispersed, and the amount of addition is large, which requires high spraying equipment, affects the spraying effect, and is likely to cause inconsistent effects.
Also because the metal substance has not been processed, during the extrusion process, due to the shear force of the screw, the original arrangement structure of the metal substance is destroyed, and the original metal performance effect is lost, so that the original effect of the metal powder coating cannot be achieved.

Abstract

The metal powder paint consists of resin, wax coated metal powder, dispersant, curing agent, leveling agent, stuffing and small amount of pigment. The production process includes heating wax to 300-320 deg.c, adding fine metal powder slowly into the molten wax under high speed ultrasonic stirring, letting stand for 3-5 hr, filtering to separate, cooling and crushing to obtain coated metal mater; mixing the metal matter with the other components inside a mixing tank, extruding the mixture into sheet, crushing in a crusher, and sieving to obtain product of required grain size. The present invention has the advantages of inhibiting burning and explosion caused by friction of metal matter to raise the safety; dispersing the metal matter on the coated surface to produce metal effect, and simple production process.

Description

(1) Technical field [0001] The invention relates to a metal powder coating and a production method. (2) Background technology [0002] At present, in order to obtain metal powder coatings with metallic luster and special texture effects, they are generally obtained by adding metal, that is, adding metal substances in the post-sequence of powder coatings. This method is prone to safety accidents such as combustion and explosion during the production process, and the metal powder coating produced is unevenly dispersed, and the amount of addition is large, which requires high spraying equipment, affects the spraying effect, and is likely to cause inconsistent effects. . Also because the metal substance has not been processed, during the extrusion process, due to the shear force of the screw, the original arrangement structure of the metal substance is destroyed, and the original metal performance effect is lost, so that the original effect of the metal powder coating cannot be...
