Abstract

The invention provides a bronze-gold-tooth colored zipper and a manufacturing method thereof. The manufacturing method comprises the following steps of: soaking a to-be-colored zipper in a bronze aqueous solution for 1-3 minutes, soaking the to-be-colored zipper in a white copper aqueous solution for 3-60 seconds after cleaning the to-be-colored zipper, and performing passivating treatment after cleaning the to-be-colored zipper again, thereby obtaining the bronze-gold-tooth colored zipper. The bronze aqueous solution consists of the following components in mass fraction: 0.8-1% of selenium dioxide, 4-5% of sodium persulfate, 3-4% of copper nitrate, 2-3% of sulfuric acid, 2-3% of nitric acid, 6-7.5% of phosphoric acid, 0.6-0.8% of sodium carbonate and the balance of water; and the white copper aqueous solution consists of the following components in mass fraction: 2-4% of stannous chloride, 5-12% of thiourea, 1-2% of hydrochloric acid, 0.4-1% of a fatty alcohol-polyoxyethylene ether emulsifier, 0.5-14% of auxiliaries and the balance of water. The method provides unique perception for the bronze-gold-tooth colored zipper, improves the zipper level, compensates the defect part between light gold color and bronze color, and meets various needs of a client.

Description

technical field [0001] The invention belongs to the technical field of surface coloring of metal materials, in particular to a bronze-gold-colored zipper and a manufacturing method thereof. Background technique [0002] Zippers can be divided into nylon, plastic steel and metal zippers according to the color of the chain teeth. With the diversification of clothing, as an important part of clothing, the tooth color of the zipper is also combined with the current fashion trend, becoming more and more colorful. There are more and more kinds of tooth colors mainly made of metal product zippers, and the production cost (coloring) of zippers is becoming more and more diverse. With the diversified needs of customers' tooth colors, a color between light gold and bronze The tooth color is favored by customers. [0003] Light gold and bronze zippers are more common in the market; however, the teeth of light gold zippers are brighter, and the production cost is higher; while the teet...
