Description

Technical Field

[0001] The invention relates to a preparation method of a degreasing agent for removing oil stains from rivet-type electric contacts and application thereof, belonging to the field of parts. Background Art

[0002] Rivet-type electrical contact materials are widely used in various relays, circuit breakers, contactors, thermostats, etc. They are important core components that affect the working reliability of switch electrical contact systems. Existing rivet-type electrical contacts have oil stains on their surfaces after being manufactured. Conventional degreasing solutions have limited cleaning capabilities for the surfaces of rivet-type electrical contacts. In some cases, oil stains remain due to incomplete cleaning, resulting in unqualified finished products.

[0003] A Chinese invention patent with application number CN 118389211 A discloses a new degreasing agent. The additives in the process configuration of this new degreasing agent are mostly strong alkaline degreasing agents, which cause serious surface corrosion to rivet electrical contacts. According to the present invention, the preparation process is simple, and the amount of additives is small, which greatly reduces the cost and operability. In addition, the appearance of the rivet-type electrical contacts obtained after cleaning has room for further improvement in actual application, so it has very important practical significance. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide a method for preparing a degreasing agent for removing oil stains from rivet-type electrical contacts and its application.

[0005] A method for preparing a degreasing agent for removing oil stains from rivet-type electrical contacts comprises the following steps: adding diethanolamine, benzotriazole, emulsifier, triethanolamine soap, sodium dodecylbenzene sulfonate, a solubilizing agent, and the rest being water into a container, and stirring for 30 minutes to obtain the degreasing agent; the degreasing agent comprises the following components in the following mass ratios: 1%-5% of diethanolamine; 0.5%-1% of benzotriazole; 5%-10% of emulsifier; 1%-5% of triethanolamine soap; 2%-4% of sodium dodecylbenzene sulfonate; 0.5%-1% of solubilizing agent; and the rest being water.

[0006] The diethanolamine, benzotriazole, emulsifier, triethanolamine soap, sodium dodecylbenzene sulfonate and other components contained in the formula work synergistically to efficiently dissolve and emulsify oil stains, especially for stubborn oil stains. By properly controlling the proportion of each component, especially the addition of the emulsifier, the degreaser maintains good stability and continuous degreasing effect during long-term use, and is not easy to decompose or deteriorate. The addition of the solubilizing penetrant allows the degreaser to penetrate deeper into the oil stains, enhances the dissolution and removal ability of the oil stains, and also has a good removal effect on the oil stains deeply embedded or solidified inside the electrical contacts. The reasonable combination of the components in the formula enables the degreaser to adapt to various types of oil stains, including oil, grease, grease-like stains and certain types of organic stains, improving the versatility and practicality of the degreaser. Through the economical formula design, it is ensured that the degreaser has a relatively low cost while effectively removing oil stains, and has a high cost-effectiveness.

[0007] The present invention also provides an application of a degreasing agent for removing oil stains from rivet-type electrical contacts. The degreasing agent is added to a container, stirred for 30 minutes, poured into a cleaning tank and heated to 40°C-60°C, and then the rivet-type electrical contacts are immersed in the cleaning tank, and ultrasonic waves are turned on for degreasing treatment. After the treatment is completed, the following steps are continued:

[0008] (1) Annealing process: the degreased rivet-type electrical contacts are loaded into a material boat and pushed into an annealing furnace for annealing;

[0009] (2) Grinding process: After the rivet-type electrical contact is annealed and cooled, it is placed in a grinding barrel and ground with grinding media;

[0010] (3) Polishing process: adding the processed rivet-type electrical contact into a centrifugal polishing machine for polishing;

[0011] (4) Cleaning process: transferring the treated rivet-type electrical contacts to a cleaning tank for cleaning and dehydration;

[0012] (5) Drying process: The dehydrated rivet-type electrical contacts are transferred to a drying tray and pushed into a drying furnace for drying.

[0013] The beneficial effects of the present invention are as follows: 1. The degreasing agent of the present invention has strong penetrating power and can quickly penetrate oil stains and peel off oil films.

[0014] 3. The degreasing agent of the present invention not only has strong cleaning power, but also has strong alkali resistance.

[0015] 4. The degreasing agent of the present invention has an outstanding emulsifying function.

[0016] 5. Compared with the prior art, the degreasing agent of the present invention has a simpler preparation process and is convenient for production. BRIEF DESCRIPTION OF THE DRAWINGS
