FAST COMPOUNDING PREPARATION METHOD FOR LONG STRIPED SILVER-GRAPHITE ELECTRICAL CONTACT MATERIAL AND SOLDER TAPE

The present invention provides a preparation method of a rapid bonding of a long silver-graphite electrical contact material and a solder strip material, including the following steps: first step, making a silver-graphite spindle into a silver-graphite electrical contact sheet material by an extrusion process; second step, performing a sintering to composite a solder strip material with the silver-graphite electrical contact sheet material to obtain a composite blank; and third step, performing a rolling and a heat treatment on the composite blank for one or more times to complete the composite of the long silver-graphite electrical contact material and the solder strip material. According to the present invention, a highly efficient and rapid composite of the long silver-graphite electric contact sheet material and the solder strip material is realized, products with good interface bonding quality and high dimensional accuracy are produced, and continuity and short process can be realized, which facilitates the realization of soldering automation. The method of the present invention is a novel method for preparing a silver-based electrical contact material and solder composite material.
