Description

Technical Field

[0001] This invention relates to the technical field of stamping oils, and specifically to a fast-drying, long-lasting rust-preventive stamping oil. Background Technology

[0002] With the rapid development of the machining industry, the demand for high-precision stamping parts is increasing day by day. In order to improve the processing accuracy of stamping parts and extend the service life of molds, the stamping oil used must have excellent lubricity and rust prevention.

[0003] Currently, there are many types of stamping oils available on the market for metal sheet stamping. These typically increase lubrication and rust prevention by adding large amounts of lubricants and rust inhibitors. However, existing oils that balance lubrication and rust prevention evaporate slowly, and prolonged residue can affect molds and subsequent processing. Oils with better volatility, on the other hand, cannot simultaneously provide both lubrication and rust prevention, resulting in slight performance deficiencies. Furthermore, existing oils have limitations in use; they cannot be used simultaneously for stamping steel and aluminum sheets due to their strong corrosiveness. Therefore, developing a fast-drying stamping oil with excellent rust prevention properties that can be used on multiple metals is a major research direction. Summary of the Invention

[0004] This invention first provides a fast-drying, long-lasting rust-preventive stamping oil. The stamping oil is made from a light alkane solvent with good volatility, a rust inhibitor prepared by multi-component compounding, as well as lubricating additives and extreme pressure agents. The preparation method is simple. The stamping oil prepared has excellent lubricity and excellent rust prevention. The oil residue after use is small and it is non-corrosive to copper and aluminum plates.

[0005] The present invention solves the technical problem by adopting the following technical solution:

[0006] This invention provides a fast-drying, long-lasting rust-preventive stamping oil, comprising, by percentage: 75%–95% alkane solvent base oil, 1%–15% lubricating additives, 3.1%–16% rust inhibitors, and 0.1%–1% extreme pressure agents; and the kinematic viscosity of the stamping oil at 40°C is 0.5–3.5 mm. 2 / s, flash point is between 40 and 90℃.

[0007] Preferably, the alkane solvent base oil is a mixture of light alkanes obtained from petroleum products.

[0008] Preferably, the carbon chain length of the alkane solvent base oil is 11-13, and the kinematic viscosity of the alkane solvent base oil at 40°C is 1-2 mm. 2 / s, flash point is between 40 and 70℃.

[0009] Preferably, the lubricating additive is selected from one or more of trimethylolpropane oleate, pentaerythritol oleate, and trimellitate.

[0010] Preferably, the method for preparing the rust inhibitor is as follows:

[0011] S11. At room temperature, mix 1.6-2.5 parts of barium dinonylnaphthalenesulfonate, 2.2-3.2 parts of barium alkylbenzenesulfonate and 4.8-6.2 parts of butyl oxyacetate, and then stir and disperse at a speed of 120-220 rpm for 10-20 min.

[0012] S12, add 0.8-1.2 parts of dodecenylsuccinic acid and 0.2-0.6 parts of N-oleoylsarcosine, and disperse by stirring at 32-36℃ for 10-20 minutes while maintaining a constant rotation speed;

[0013] S13. After cooling to room temperature, add 0.9 to 1.3 parts of N-acetylbenzotriazole, and stir for 20 to 30 minutes while maintaining the same speed to obtain the rust inhibitor.

[0014] Preferably, the extreme pressure agent is selected from one or more of triphenyl phosphite, triethyl phosphite, trilaurate phosphite, tricresyl phosphate, oleic acid ester, and butoxyethyl phosphate.

[0015] Preferably, the method for preparing the stamping oil includes the following steps:

[0016] S21. Under normal pressure, set the stirring temperature to 10-30℃ and the stirring speed to 80-100 rpm. Slowly add the alkane solvent base oil and lubricating additive to the stirrer, start stirring, and stir for 15-25 minutes.

[0017] S22. Slowly add the rust inhibitor and extreme pressure agent to the stirrer in sequence, adjust the speed to 180-220 rpm, and stir for 30-40 minutes.

[0018] S23. Reduce the speed to 50-70 rpm, stir for 1-3 hours, and then let stand for 10-20 minutes to obtain the stamping oil.

[0019] The beneficial effects of this invention are:

[0020] This invention discloses a fast-drying, long-lasting rust-preventive stamping oil. It utilizes a light alkane solvent with good volatility, low odor, and low flash point, a multi-component compound rust inhibitor, lubricating additives, and extreme pressure agents. The preparation process is simple and easy to implement. The combination of barium dinonylnaphthalenesulfonate, barium alkylbenzenesulfonate, and butyl oxyacetate in the rust inhibitor effectively improves the oil's adsorption capacity on metal surfaces. The use of dodecenylsuccinic acid and N-oleoylsarcosine enhances the mutual penetration and uniform dispersion of the components. Finally, N-acetylbenzotriazole is added to help prevent or slow down metal corrosion. The compounded use of these components forms a denser and more stable protective film on the metal surface, providing longer-lasting rust protection for the sheet metal. Under the preparation process, composition, and parameter conditions of this application, the prepared stamping oil ensures excellent lubricity while exhibiting excellent rust prevention. It leaves minimal oil residue after use and is non-corrosive to copper and aluminum sheets, meeting process requirements while optimizing production. Detailed Implementation
