Blue-light copper-gold powder for metal spraying and preparation method thereof

Abstract

The invention discloses a blue-light copper-gold powder for metal spraying and a preparation method thereof. The method comprises the following components of, by mass, 70-74% of copper, 22-28% of zincand 1-2% of polyethylene glycol solution; and after the procedures of smelting, ball milling, grading and polishing, colored alloy pigment with different particle sizes scaly-shaped structures is obtained, wherein the particle sizes range from 2 micro to 40 micro, and the appearance of the colored alloy pigment is blue light. According to the method, the addition of an adhesive or other compositions is reduced, the blue-light copper-gold powder is made into a scaly shape which is in a micron-grade and in a blue-light color, the use performance is more facilitated, meanwhile, the risk of oxidation is also reduced.

Description

technical field [0001] The invention relates to a leafing type metallic pigment, in particular to a bronze copper-gold powder for metal spraying and a preparation method thereof. Background technique [0002] At present, the use of floating metal pigments is more and more extensive, which is suitable for gold paint, paint, flying gold, hot stamping, spraying, color masterbatch, handicrafts, screen printing gold, gold paint spraying, fabric printing gold, etc. , most of the existing metallic pigments add more binders or various functional compositions, although they can play a corresponding role, but at the same time there will be other subsidiary disadvantages, such as easy to be oxidized or poor performance Wait. Contents of the invention [0003] In order to solve the problems in the above-mentioned background technology, the object of the present invention is to provide a kind of bronze copper gold powder for metal spraying and its preparation method, reduce the additi...
