Abstract

The invention relates to an additive for etching magnesium or magnesium alloy, which comprises the following chemical substances of 10-60 percent of carboxylic ester or carboxylic acid or mixture of the carboxylic ester and the carboxylic acid, 5-40 percent of alkane, 2-25 percent of surfactant, 0.01-2 percent of defoaming agent, 0.01-2 percent of tackifier and the balance of distilled water. By using the additive to prepare an etching solution, the etching solution has long service life, the process is stable, the etched plate face is smooth and complete, subsequent processing is not required, during etching large-surface concave texture layout, the difference between an edge and a center region is small, gradient is easy to be etched at an edge part and is an obtuse-angle slop, moreover, the etching speed is high, and the etching depth is deep.

Description

technical field [0001] The invention relates to an additive formula for chemical etching of magnesium or magnesium alloy materials and a preparation method thereof. Background technique [0002] In the early 1990s, British Yili Kechuang Company put magnesium alloy etching plates on the market. Compared with copper and zinc alloy templates, magnesium alloy etching templates have small specific gravity, fast heat dissipation, high surface hardness, easy demoulding, and neat slopes. Good continuity, smooth edges, convenient plate bonding, hot stamping speed, high printing durability, etc. At the same time, unlike copper and zinc heavy metal ions, magnesium ions do not pollute the environment. The magnesium alloy etching template not only effectively improves the stamping speed and quality, but also saves labor costs, and its superiority is quickly recognized by the industry. At present, America and Europe are engaged in plastic drop, leather embossing, high frequency mold, the...
