Abstract
Description
Technical Field
[0001] This invention belongs to the field of lubricant technology, specifically a water-based lubricant for steel material stretching and stamping. Background Technology
[0002] To improve the efficiency of metal processing, enhance product quality, reduce tool wear, lower frictional resistance, and save energy, it is essential to select appropriate lubricants. Except for special cases where a small amount of solid lubricant is used, liquid lubricants are generally employed. Based on their form, metalworking lubricants are divided into two main categories: oil-based and water-based. Water-based lubricants are made from mineral oils, synthetic hydrocarbons, and animal and vegetable oils, and are truly soluble in water.
[0003] Existing products used for stamping and drawing copper tubes are emulsified products with a high oil content. These products are difficult to clean after stamping and drawing and are prone to deterioration during use, affecting product performance and lifespan. Furthermore, they are not suitable for use with ferrous materials. Summary of the Invention
[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a water-based lubricant for steel material stretching and stamping. This technical solution involves designing a low-oil-content semi-synthetic microemulsion product, a water-based lubricant for copper and iron material stretching and stamping, which achieves a high-oil-content stretching and stamping effect through additive formulation. Because of its low oil content and microemulsion state, it is easy to clean after stretching and stamping. Its diluted solution is less prone to deterioration during use, ensuring its service life. The undiluted solution can be used for stretching and stamping iron materials, exhibiting excellent rust prevention and easy cleaning; rinsing with water is sufficient.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a water-based lubricant for steel material stretching and stamping, the water-based lubricant comprising the following components in parts by weight: 10-30% base oil; 5-20% extreme pressure chlorine and phosphorus additives; 5-20% surfactant; 5-15% rust inhibitor; 30-50% deionized water; and 1-3% other additives.
[0006] Preferably, the water-based lubricant comprises the following components in parts by weight: 20-30% base oil; 5-10% extreme pressure chlorine and phosphorus additives; 10-15% surfactant; 10-15% rust inhibitor compound; 40-50% deionized water; and 2-3% other additives.
[0007] Furthermore, the base oil is one or more of polyethylene glycol, phosphate ester, silicone oil, and vegetable oil.
[0008] Furthermore, the extreme pressure chlorine and phosphorus additives are one or more of chlorinated paraffin, carbon tetrachloride, sulfurized phosphate, and zinc dialkyl dithiophosphate.
[0009] Furthermore, the surfactant is one or more selected from sulfurized castor oil, sodium dodecyl sulfate, benzyl ammonium chloride, polysorbate, polyoxyethylene fatty alcohol ether, and benzalkonium chloride.
[0010] Furthermore, the rust-inhibiting composite agent is formulated from organic zinc chelates, amide activators, and rust and corrosion inhibitors.
[0011] Furthermore, the other additives are one or more of antioxidants, dispersants, anti-wear agents, and emulsifiers.
[0012] This invention also provides a method for preparing a water-based lubricant for steel material stretching and stamping, the method comprising the following steps:
[0013] (1) Add the base oil to the mixing tank;
[0014] (2) Start stirring and heat to 45±5℃, then add extreme pressure additives and surfactants in sequence and stir at constant temperature for 1 hour before stopping heating;
[0015] (3) Add deionized water and rust inhibitor additive in sequence and stir for 45 minutes until transparent;
[0016] (4) Add other additives in sequence and stir for 30 minutes.
[0017] The beneficial effects of the present invention using the above structure are as follows: (1) The lubricating oil provided by the present invention is applicable to both non-ferrous and ferrous metals, easy to clean, does not easily become smelly or deteriorate, has a long service life, and effectively reduces the cost of product use; (2) The present invention designs a semi-synthetic microemulsion product with low oil content, which is a water-based lubricant for stamping and stretching of copper and iron materials. Through the compounding of additives, it achieves a high oil content stamping and stretching effect; (3) The present invention has low oil content, microemulsion state, and is easy to clean after stamping and stretching. Its diluted solution does not easily deteriorate during use, ensuring its service life. At the same time, its original solution can be used for stamping and stretching of iron materials, has excellent rust prevention and is easy to clean, and can be rinsed with water.
