Abstract

The invention relates to a metal chromium waterborne mirror-like silver pigment and a manufacturing method thereof. The pigment contains the following components in percentage by weight: 10%-30% of metal chromium slice particles, 70%-88% of a dispersing agent and 0-2% of an aid. The manufacturing method comprises the following steps: (1) coating a plastic film base material with a resin layer witha thickness of 1-1.2 microns; (2) depositing metal chromium on the surface of the resin layer by virtue of a continuous winding type magnetron sputtering method, so as to form a nano-chromium film; and (3) crushing a mixed solution containing a solvent, resin and a fine chromium slice, filtering, adding the aid, adjusting the sold content, so as to obtain the metal chromium waterborne mirror-likesilver pigment containing the metal chromium slice particles, the dispersing agent and the aid. According to the pigment, chromium is taken as metal chromium mirror-like silver of the material, the same mirror surface effect is preserved, and meanwhile, the problems that existing mirror surface aluminum cannot resist water and corrosion are solved, so that the application field of the mirror-likesilver pigment is extended from a waterborne system to a UV system, and the pigment is accordant with the environment-friendly demands.

Description

technical field [0001] The invention relates to the technical fields of ink and paint, in particular to a metallic chromium water-based mirror silver pigment and a manufacturing method thereof. Background technique [0002] Mirror silver is a high-grade metal pigment made of aluminum with nano-thick aluminum flake particles dispersed in organic solvents. After printing or spraying the mirror ink / paint prepared with it on the printing surface, the nano-aluminum flakes are arranged parallel to each other. , thus forming a light reflection effect like a silver mirror, hence the name "mirror silver". [0003] Because aluminum will undergo a hydrogen release reaction when it meets water, the existing mirror silver is only used in oily ink / coating systems and cannot be used in water-based systems; in addition, aluminum is not resistant to acids and alkalis, even in oily systems, mirror silver is not suitable for the preparation Resins and solvents used in inks / coatings are also v...
