Embodiment

[0084] Hereinafter, although an Example demonstrates this invention, this invention is not limited to an Example.

[0085] (Preparation of metal adsorption components)

preparation example 1

[0086] OL-Ca

[0087] Into a 500 ml flask, 50 g (acid value: 0.163 mol) and 50 mL of methanol were added ("Phoslex A18D" manufactured by SC Organic Chemical Co., Ltd., molecular weight: 467 (average), acid value: 183 mgKOH / g) and methanol, and stirred at room temperature. , to make a homogeneous solution. 6.04 g (0.0815 mol) of calcium hydroxide was added thereto. The suspension was stirred for 24 hours while maintaining room temperature, and after confirming the disappearance of the calcium hydroxide precipitate, it was filtered, and methanol and generated water were distilled off under reduced pressure using a rotary evaporator. Next, after adding 50 mL of toluene, similarly distilled off under reduced pressure, the generated water was distilled off by azeotropy to obtain the target product as a clear viscous substance.

Abstract

Provided is a corrosion inhibitor that, when used on a connection section of a covered electrical cable with a terminal, said covered electrical cable having a covering material that includes a plasticizer, maintains anticorrosive performance even if exposed to high temperatures. Also provided is a covered electrical cable with a terminal, the anticorrosive property of said covered electrical cable having been improved using said corrosion inhibitor. A corrosion inhibitor including a base oil (A) that has a viscosity of 30 mPa.s or greater at 100 DEG C, and a metal adsorption component (B) that includes a phosphorus compound, wherein the mass composition ratio of (A) to (B) is within the range of (A):(B)=50:50 to 98:2. A covered electrical cable 1 with a terminal, wherein a film 7 comprising the corrosion inhibitor of the present invention covers a part 6 where a terminal metal fitting 5 and an electrical cable conductor 3 are electrically connected.

Description

technical field [0001] The present invention relates to corrosion inhibitors and coated electric wires with terminals. Background technique [0002] In order to prevent corrosion at the connecting portion between the core wire (wire conductor) of the covered electric wire with a terminal and the terminal fitting, the connecting portion is sometimes coated with an anti-corrosion agent to perform anti-corrosion treatment. Such anti-corrosion treatment is effective, for example, at portions where the core wire is an aluminum-based material and the terminal fitting is a copper-based material, where there are dissimilar metal contact portions at the connecting portion and corrosion is particularly prone to occur. [0003] Conventionally, grease has been used for metal equipment and metal parts for the purpose of lubrication, corrosion prevention, and the like. However, since grease has a high viscosity at room temperature, it is difficult to apply it thinly and uniformly. There...
