Embodiment 19

[0069] According to the design ratio, it is melted in an induction furnace with a melting temperature of 500-600°C and a refining temperature of 600-750°C. It is refined with a commercially available refining agent. After the refining is completed, a φ50 casting rod is continuously cast horizontally.

[0070] The chemical composition analysis results of the cast rod are as follows (% by weight): Cu 2.425 Al 2.072 Mg 0.100 Bi0.0001 Ni0.13%, Si 0.056%. The balance is Zn.

[0071] The cast rod is sawed and cut to the designed length, kept at 300°C for 2 hours, and then extruded into a billet of φ8.0. The extruded billet is stretched through multiple passes, stretched to a flattened round billet, and undergoes 2 times of annealing and rapid cooling in the middle. It is then flattened to a flat wire stock, with an annealing in between. The flat wire blank is rolled and drawn to make a flat wire with a specification of 0.9×3.95. The produced flat wire is discharged on the rice di...

Abstract

The invention discloses a zinc-alloy zipper tooth belt produced by a row microphone method, in particular to zinc alloy for a zipper tooth belt and a preparation method of the zipper tooth belt. The alloy comprises the following components by weight percent: 0.5-5% of Cu, 10-4.5% of Al, 0.01-0.2% of Mg and the balance of X, Y, Zn and unavoidable impurities, wherein the sum of the percentages of the components is 100%; the X is selected from at least one of 0.0001-0.5% of Bi, 0.01-0.19% of Ti, 0.001-0.3% of RE, 0.001-1% of Ni and 0.001-1% of Si; and Y is selected from at least one of Mn, Co, Nb, Zr, Cr, Ca, P, Sb, Te and Se. By adopting the deformed zinc alloy and the alloy producing method disclosed in the invention, the production of the zipper line can be met, and the zipper tooth belt can be produced smoothly by the row microphone method; and the produced zipper can be processed into different colors.

Description

technical field [0001] The invention relates to a zinc alloy and an application thereof, in particular to a zinc alloy for a zipper tape and a method for preparing the zipper tape. Background technique [0002] The invention and application of zippers have a long history. At present, there are many varieties and styles of zippers, which are widely used in daily life such as clothing, shoes and hats, bags, tents, toys, etc., bringing great convenience to people. . A simple zipper involves cloth tape, chain teeth, upper and lower buckles, sliders and accessories, and each item involves different materials. Chain tooth materials are the most used materials, mainly metal, plastic and nylon, and the metal materials used are mainly copper alloys. Commonly used copper alloys are brass such as H65, H68, H85, H90 and BZn12-24 zinc white copper, and the market demand is very large. Copper alloys account for about 70% of the cost of zippers, and cost and resource issues are graduall...
