Problems solved by technology

However, if the oil component is applied too thinly, it will be difficult to maintain a stable oil film on the metal surface for a long time
Especially under high temperature conditions, evaporation or molecular weight reduction due to oxidation of oil components may occur, making it more difficult to maintain a stable oil film on metal surfaces

Abstract

The present invention provides a surface protective agent composition, an electrical connection structure using the composition, and a method for manufacturing an electrical connection structure. The surface protective agent composition inhibits the corrosion of adjacent metal parts of different types due to corrosion currents therebetween. of corrosion. In the surface protective agent composition and the electrical connection structure having a surface protective layer containing the surface protective agent composition, the surface protective agent composition is obtained by mixing (b) into (a) lubricating oil base oil. A specified amount of at least one compound selected from a specific phosphorus compound and its metal salt or amine salt, and (c) a specified amount of an amide compound; when component (b) does not contain a metal salt of a phosphorus compound, (b) is also added d) Specified amounts of specific metal salicylates and / or (hyper)basic salts thereof.

Description

technical field [0001] The present invention relates to a surface protective agent composition, an electrical connection structure using the composition, and a method for producing the electrical connection structure. More specifically, the present invention relates to a surface protective agent composition excellent in corrosion inhibition ability to metal parts, An electrical connection structure using the composition and a manufacturing method of the electrical connection structure. Background technique [0002] At the place where two metal parts such as the terminal and the electric wire or the fitting part between the terminals are electrically connected, there is a material constituting the terminal and the electric wire, a material constituting one of the terminal and the opposing terminal, or a metal plate constituting the terminal and The case where the material of the plated layer formed on the surface of the metal plate is made of different metals. [0003] When ...
