Problems solved by technology

In the implementation process of this coloring process, the process of depositing pure copper needs to be completed under boiling conditions, which has high energy consumption and cost, and the color of the obtained color film layer is relatively light and the bonding force is not high. At the same time, its color fastness to washing The degree and corrosion resistance are not good, so it is not conducive to large-scale application

Abstract

The invention provides a coloration process of a brass zipper. The coloration process comprises the following steps of a) chemical deoiling treatment; b) chemical polishing treatment; c) activation treatment; d) chemical coloration treatment; and e) post treatment. The invention discloses the coloration process of the brass zipper; the coloration process is simple, feasible, low in energy consumption and low in cost; through optimizing the constitution of a coloration solution and a process condition, not only is the higher bonding force of a colored film ensured, but also the better color fastness to washing and the corrosion resistance of the colored film are ensured; and the coloration process has higher popularization and application value.

Description

technical field [0001] The invention relates to a coloring process, in particular to a brass zipper coloring process, and belongs to the technical field of zippers. Background technique [0002] Zipper is an important livelihood product, widely used in clothing, bags, shoes and other daily necessities. Among them, brass zippers have the unique texture and nobleness of metal, and are often used in various high-end products to improve the decoration and competitiveness of the products. In order to improve the service life of the brass zipper and increase the aesthetics, it is usually necessary to carry out necessary surface coloring treatment on the brass zipper. Brass is a kind of copper metal. Among the current copper metal coloring formulas, the commonly used coloring formulas mainly include copper-ammonia salt system and sulfide system. [0003] At present, the surface coloring process of brass zippers is usually divided into two steps: first deposit a layer of pure copp...
