Abstract

The invention relates to a producing method for a silver oxide welding material. The method comprises the steps of (1) cleaning the surface of a stainless steel band; (2) feeding silver oxide powder in a spraying machine, and fixing the spraying machine on a movable device to be moved at the uniform velocity; (3) coating a layer of glue on the upper surface of the stainless steel band; (4) starting the spraying machine to spray the upper surface of the stainless steel band to form a coating, repeating spraying for 2 to 4 times, and performing natural cooling; (5) performing same treating on the lower surface of the stainless steel band to obtain the silver oxide welding material eventually. According to the method, the silver oxide welding material is produced through a glue mode, so that the method is simple, the operation is facilitated, the obtained welding material is flat in surface, and as for the performance, silver has good electrical conductivity and mobility, so that the wetting power between the welding material and a substrate during welding is high, and the joint toughness is good. Besides, the welding material can be used as a base material, and welding materials of different specifications after binding pressing are obtained.

Description

technical field [0001] The invention relates to a preparation method of silver oxide welding material. Background technique [0002] Silver has good electrical and thermal conductivity. As a welding material, the welding point is flat, and the contact resistance is low and stable. Conventional welding materials are prepared by smelting. Due to the mixing of different materials, the cold rolling process will also cause uneven distribution of components. The price of silver is expensive, because it is necessary to adopt a preparation method that efficiently utilizes silver materials to improve the quality and performance of welding materials. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a preparation method of silver oxide soldering material. [0004] In order to solve the problems of the prior art, the technical solution adopted by the present invention is: a preparation method of silver oxide soldering material, c...
