Technical Field

The invention belongs to the field of surface treatment of rivet electrical contacts, and particularly relates to a cleaning agent for removing stains on the surface of a rivet electrical contact and application thereof.

Background

Rivet electrical contacts used in electrical products are currently mostly produced by automated processing, in which all riveting material is fed by a stainless steel vibrating disk. The inventor finds that flaky black stains are attached to the surface of the rivet electrical contact after the rivet electrical contact vibrates on the vibration disc for a long time, contact resistance is affected, and the fact that a stain film exists on the surface of the rivet electrical contact through investigation and the stain film is gathered after the rivet electrical contact rubs with the vibration disc for a long time to form the flaky black stains is confirmed. Therefore, it is necessary to develop a cleaning agent for removing the stain film on the surface of the electrical contact for corresponding improvement.

Disclosure of Invention

The invention aims to overcome the defects and shortcomings of the prior art, and provides a cleaning agent for removing stains on the surface of a rivet electrical contact and application thereof.

In order to achieve the purpose, the first aspect of the invention provides a cleaning agent for removing stains on the surface of a rivet electrical contact, which comprises the following components.

The second purpose of the invention is to provide an application of the cleaning agent in improving the contact resistance of the rivet electrical contact, wherein the rivet electrical contact is soaked in the cleaning agent, is cleaned by ultrasonic heating for at least 5min, is taken out, and is rinsed by hot water, dehydrated and dried.

The ultrasonic cleaning parameters are further set as follows: cleaning with 40Hz ultrasonic wave for 10 min.

Compared with the prior art, the invention has the following advantages: the rivet electrical contact is soaked in a cleaning agent formed by mixing caustic soda, sulfonic acid, phosphoric acid, oxalic acid and pure water, and the synergistic effect of the caustic soda, the sulfonic acid, the phosphoric acid and the oxalic acid is utilized to weaken and separate the adhesive force of stains on the surface of the rivet electrical contact, so that the aim of removing stain films is fulfilled, the surface cleaning performance of the electrical contact is improved, and the generation of the stains after vibration is reduced.
