Formula and preparation method of mixed type flashing silver powder

Abstract

The invention provides a formula and preparation method of mixed type flashing silver powder. The formula is prepared from the following components in percentage: 45 percent to 48 percent of epoxy resin, 45 percent to 48 percent of polyester resin, 0.5 percent to 1.0 percent of titanium white, 2 percent to 5 percent of precipitated barium sulfate, 1 percent to 1.2 percent of an efficient leveling agent, 0.8 percent to 1.1 percent of a luster enhancing agent, 0.5 percent to 0.8 percent of a degassing smoothing agent and 0.5 percent to 0.8 percent of a silver powder orientation agent; a pigment is added into the flashing silver powder. By adopting the formula and the preparation method, a coating applicable to a metal surface is prepared and has strong flashing effect; the product is applicable to metal article coatings with high standards and high requirements, replaces paint with the similar effect, does not contain volatile matters and is efficient and safe to use.

Description

technical field [0001] The invention relates to the field of powder coating manufacture, in particular to a formula of mixed flash silver powder and a preparation method thereof. Background technique [0002] At present, when coating the metal surface, paint is usually used as the coating raw material to protect the metal surface from oxidation and have a beautiful appearance. However, due to the volatile substances of the paint, the paint will volatilize after spraying, resulting in a greatly reduced spraying effect. And it is easy to spray randomly when in use, causing pollution. Therefore, it is particularly important to solve the problems that paint spraying is easy to volatilize and cause pollution. Contents of the invention [0003] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a formula and a preparation method of a mixed flash silver powder, which is suitable for coating on metal surfaces thro...
