Abstract

The invention discloses a copper-zinc alloy plasticizing process for increasing the binding force of copper-zinc alloy with epoxy resin. The process comprises the following steps: 1) cleaning and oil removal: removing dirt and grease on the surface of the copper-zinc alloy; 2) micro-etching: conducting micro-etching on the surface of the copper-zinc alloy by a chemical method, so as to increase the reaction area of copper-zinc alloy with plasticizer; and 3) plasticization: depositing a layer of an azole copper zinc mixture generated from reaction of epoxy chloropropane, pentyl benzimidazole with copper zinc on the copper-zinc alloy surface subjected to micro-etching, the mixture layer has strong bonding force with epoxy resin. The copper-zinc alloy treated by the invention can be directly laminated with epoxy resin; and compared with the traditional sand blasting process, the method saves power consumption, reduces a lot of manual work, improves production efficiency, and avoids the dust and noise pollution.

Description

technical field [0001] The invention relates to a method for plasticizing a copper-zinc alloy. Background technique [0002] With the increasing development of the electrical cable industry, the market has higher requirements for product functionality, appearance requirements, anti-corrosion capabilities, and environmental protection. Therefore, the process of die-casting epoxy resin on the copper-zinc alloy cable is also proposed Higher electrical performance, environmental protection, binding force and other requirements. At present, the common practice is to sandblast the copper-zinc alloy to increase the roughness of the copper-zinc alloy surface to improve the bonding force between the copper-zinc alloy rod and the epoxy resin, and this process will cause a lot of dust and noise pollution . Contents of the invention [0003] The invention provides a bonding layer that can deposit a layer of copper-zinc and organic matter on the copper-zinc alloy by means of chemica...
