Problems solved by technology

At present, there are several types of composite microwires. One type is mainly glass-coated copper wire and glass-coated stainless steel wire prepared by melt spinning. Due to the small molten pool of glass, it is difficult to stabilize the process. Core wire and glass-coated wire The thickness of the cladding layer varies greatly in the direction of the length of the composite wire, which may cause instability in the performance of components
The other is bimetallic composite wires prepared by plastic processing methods, such as copper-clad aluminum, silver-clad aluminum, aluminum-clad steel, etc. Due to the limitations of the properties of the two metals and processing technology, the type and range of composite wires are subject to certain restrictions. limitations
There is also a class such as enameled wire, etc., but the composite wire produced by this type has poor high temperature resistance

Abstract

The invention discloses a stainless steel / glass / copper-clad composite wire and a preparation method thereof. The shape of a section of the composite wire can be a circle or a flat shape or a rectangle, the composite wire is made of stainless steel, glass and copper from inside to outside, and the outer-cladding layer, namely the copper, is prepared through chemical plating and electric plating methods. The preparation method of the composite wire comprises the process steps that (1) a stainless steel wire is subjected to deoiling and degreasing; (2) glass is prepared through a fusion pultrusion method to clad the stainless steel wire; (3) surface treatment is carried out on the glass-clad stainless steel wire; (4) the roughened glass-clad stainless steel wire is activated by hydrogen peroxide and a concentrated sulfuric acid solution; (5) chemical copper plating is carried out on the glass-clad stainless steel wire; and (6) the copper cladding layer is subjected to brushing electroplating.

Description

technical field [0001] The invention relates to multi-material clad composite wires, in particular to a stainless steel / glass / copper / clad composite wire and a preparation method thereof. Background technique [0002] With the development of information technology, higher requirements are put forward for the use occasions and performance of metal composite microwires, which should have higher sensitivity, faster response, high temperature resistance, corrosion resistance and other properties. All of these force the production of thinner and better performance composite microfilaments. At present, there are several types of composite microwires. One type is mainly glass-coated copper wire and glass-coated stainless steel wire prepared by melt spinning. Due to the small molten pool of glass, it is difficult to stabilize the process. Core wire and glass-coated wire The thickness of the cladding layer varies greatly in the length direction of the composite wire, which may cause ...
