preparation example Construction

[0059] The present invention also provides a kind of preparation method of metal slide fastener, comprises the following steps:

[0060] A) degreasing the teeth of the metal zipper;

[0061] B) cleaning and coloring the degreased teeth to obtain colored teeth;

[0062] C) cleaning and dehydrating the colored teeth;

[0063] D) oiling the dehydrated teeth to obtain a metal zipper;

[0064] The coloring agent used in the coloring is the metal zipper coloring agent mentioned above.

[0065] In some embodiments of the present invention, the metal zipper is a brass zipper.

[0066] The present invention first degreases the teeth of the metal zipper to remove the oil stains on the teeth of the metal zipper. The degreasing agent used for the degreasing is preferably an alkaline degreasing agent. In some embodiments of the present invention, the degreaser is a commercially available alkaline degreaser HP-201A.

[0067]Before the degreasing, it is preferable to polish the teeth o...

Abstract

The invention provides a metal zipper coloring agent. The metal zipper coloring agent comprises a material a of 20 to 100 g/L, a material b of 10 to 120 g/L, sodium sulfate solid of 0 to 100 g/L and the balance of water, wherein the material a is selected from one of sodium chlorite solid, sodium persulfate solid and potassium persulfate solid; and the material b is selected from sodium hydroxidesolid or potassium hydroxide solid. The metal zipper coloring agent is prepared from the components with specific proportion; by the metal zipper coloring agent, the metal zipper takes on olive color,the color is the color that the existing metal zipper does not take on, the coloring quality is excellent, and the color is not liable to lose; meanwhile, the durability of the zipper is excellent.

Description

technical field [0001] The invention belongs to the technical field of zipper production, and in particular relates to a metal zipper colorant, a metal zipper and a preparation method thereof. Background technique [0002] Metal zippers are one of the three major zipper product categories. Because of its high strength and strong metal texture, it has been favored by the market, and it is the main choice for jackets and luggage zippers. However, due to the limitations of the processing technology of metal zippers, the material currently used is mainly copper zippers. However, the surface coloring process of copper has many limitations due to the particularity of the zipper itself. Therefore, there are not many types of processes that can really be used for the surface coloring of metal zippers. As a result, metal zippers have been black, white, gold, and ancient for many years. Mainly silver, bronze and rose. Compared with resin and nylon zippers and metal zippers, the col...
