Preparation method of anti-rust emulsion oil for ultra-fine copper wire drawing and strategy for improving anti-rust and cleaning performance
I. Introduction
When high-speed wire drawing, the friction is intensified, the temperature of the drawing oil is overheated, which may accelerate the qualitative change, resulting in the formation of sludge, copper soap and other oxidation byproducts. The main function of copper wire drawing oil is to reduce the friction between copper wire and wire drawing die and guide wheel, and provide lubrication protection; Improve the brightness of copper wire surface, prevent wire rust; The metal dust in the die hole can be removed by means of spray or immersion. Reduce the temperature of metal wire and die hole to prevent oxidation discoloration. In the process of ultrafine copper wire drawing, the application of emulsified oil plays a crucial role. It not only provides the necessary lubrication and cooling for the copper wire, but also has excellent anti-rust properties to ensure the quality and production efficiency of the copper wire. In this paper, the preparation method of anti-rust emulsion oil for ultra-fine copper wire drawing is introduced in detail, and how to improve its anti-rust and cleaning properties is discussed.
2. Preparation method of ultra-fine copper wire drawing anti-rust emulsion oil
The preparation of ultra-fine copper wire drawing anti-rust emulsion oil is a fine and complicated process, which mainly involves the selection of raw materials, the determination of the ratio and the control of the preparation technology.
1. Raw material selection: Select high-quality
Base Oil, emulsifier, rust inhibitor, oil agent and other raw materials to ensure the basic performance of emulsified oil.
2. Ratio determination: According to the production demand and raw material characteristics, determine the ratio of each raw material. In general, the base oil accounts for a large proportion, and the amount of additives such as emulsifiers and anti-rust agents is adjusted according to specific needs.
3. Preparation process: The selected raw materials are added to the reactor in a certain order for heating, stirring and other treatment. During the preparation process, parameters such as temperature and stirring speed should be strictly controlled to ensure the quality and stability of the emulsified oil.
[Preparation method] Add No. 5 white mineral oil, vegetable oil, Archean oil, 65%~40% sodium petroleum sulfonate, 0P-10, and benzotriazole of the active substance into a high shear emulsifier with a rotating speed of 1800~2000r/min and stir evenly, then add water, and continue to stir for about 40min until the original liquid becomes turbidized and transparent. After the stock solution is diluted by 1: (15~ 20), the anti-rust emulsion oil for drawing of ultra-fine copper wire can be directly used.
[Raw material matching] The mass ratio of each component of this product is: No. 5 white mineral oil 45~50, vegetable oil 6~10, Archean oil 6~10, the active substance 65%~40% sodium petroleum sulfonate 10~14,OP ~ 108~12, benzotriazole 0.2 ~ 0.6, water 12~ 16.
Third, strategies to improve the anti-rust and cleaning performance of emulsified oil
In order to further improve the anti-rust and cleaning performance of emulsified oil, we can consider and optimize from the following aspects:
1. Preferred raw materials: The selection of excellent anti-rust agents and cleaning agents as additives to improve the anti-rust and cleaning performance of emulsified oil. For example, rust prevention agents such as benzotriazole, which has a strong anti-rust function, and cleaning agents such as surfactants, which have high cleaning capacity, can be selected.
2. Optimize the ratio: Adjust the ratio of each raw material according to the actual demand. Appropriately increasing the amount of anti-rust and cleaning agent can improve the anti-rust and cleaning properties of emulsified oil. However, it should be noted that too many additives may affect the stability and cost of emulsified oil.
3. Improve the preparation process: improve the dispersion and stability of the emulsion oil by improving the preparation process. For example, the use of equipment such as high-shear emulsifiers can make the raw material more fully mixed and dispersed, thereby improving the performance of the emulsified oil.
4. Adding additives: Adding some additives to the emulsified oil, such as antioxidants, preservatives, etc., can extend the service life and stability of the emulsified oil. These auxiliaries can improve the anti-rust and cleaning properties of emulsified oil to a certain extent.
5. Research and development of new emulsified oil: With the continuous progress of science and technology, the research and development of new emulsified oil is also continuing. Through the development of new emulsified oils, its rust prevention and cleaning properties can be further improved to meet higher production needs.
6. Conclusion
Anti-rust emulsion oil is an indispensable auxiliary material in the process of copper wire drawing. The emulsified oil with excellent properties can be prepared by optimizing the selection of raw materials, the determination of ratio and the control of preparation technology. At the same time, by adopting a series of strategies to improve the anti-rust and cleaning performance, the performance level of emulsified oil can be further improved, providing a more reliable guarantee for copper wire drawing production.
