High-performance punching oil used for thick plate

Abstract

The invention discloses high-performance punching oil used for a thick plate, belongs to the field of metal processing operating fluid, and particularly relates to operating fluid for metal stamping processing. The high-performance punching oil comprises, by mass, 60%-80% of refined mineral oil, 5%-10% of a sulfur-containing extreme pressure agent, 5%-15% of a macromolecule polymerization ester extreme pressure agent, 0.5%-5% of an antiwear agent and 5%-10% of an antirust agent. One of sulfide aliphatic acid ester and over-based sulfosalt or a mixture of the sulfide aliphatic acid ester and the over-based sulfosalt is selected as the sulfur-containing extreme pressure agent. Polyheptadecylimidazoline-di-isooctyl borate is selected as the macromolecule polymerization ester extreme pressure agent. According to the high-performance punching oil, under the synergistic effect of the macromolecule polymerization ester extreme pressure agent and the sulfur-containing extreme pressure agent, excellent lubricating performance and anti-corrosion performance can be given to the punching oil, and the high-performance punching requirements for the thick plate are met. Moreover, the rusting problem of punched products and the ecological environment problem are solved without chlorinated paraffin.

Description

technical field [0001] The invention relates to a high-performance stamping oil used for thick plates, which belongs to the field of working fluids for metal processing, in particular to working fluids for metal stamping processing. Background technique [0002] The development of stamping technology began with the industrial production of automobiles. At the beginning of the 20th century, the industrialized production of Ford Motor in the United States greatly promoted the research and development of stamping technology. The 1960s was an important period for the development of stamping technology, and various new forming technologies appeared one after another. In 1923, the fine blanking technology was first proposed by the German F. Schiess. In 1924, F. Schiess established the world's first fine blanking factory in Lichtensteig, Switzerland. [0003] The fine blanking process is a part stamping technology that can be made in one process and immediately used for assembly,...

Problems solved by technology

[0006] Chinese patent CN201210508661.6 discloses a metal stamping oil and its preparation method, which consists of the following components: 80% to 85% mineral base oil, 4% to 6% alkylphenol polyoxyethylene ether phosphate, 6%~7% lauryl alcohol polyoxyethylene ether, 2%~3% sorbitan fatty acid ester and 3%~4% fatty amine have good lubricating properties, but the oil can be emulsified when it meets water, which will affect the product antirust effect; CN201310561374 discloses a stamping forming lubricant for automobile plate components, which consists of 6% to 8% antiwear agent, 6% to 8% oily agent, 0.5% to 1.0% antirust agent, and 0.001% to 0.005% antifoam agent, 0.5% to 1.0% antioxidant, 0.1% to 0.5% metal deactivator, and the balance is composed of base oil. Trimethyl phosphate and sulfurized isobutylene are used to compound to meet the lubrication requirements. This invention can only be used for thin plates. Stamping cannot meet the lubrication requirements of thick plate stamping; CN201510117670 discloses a high-performance environment-friendly medium and long-term anti-rust stamping oil, which consists of 5% to 10% synthetic lubricant, 10% to 25% antirust agent, 1% to 10% %Extreme pressure antiwear agent, 0.2%~1% metal deactivator, 1%~3% surfactant, 10%~30% refined mineral oil, 30%~60% refined solvent oil, using modified vegetable oil or polyol esters to achieve the lubricating effect, while the modified vegetable oils and polyol esters are unstable, and a reversible esterification reaction will occur at a certain temperature, and the acidic substances produced will corrode the surface of the material

None of the above patents involves the technical report on improving the lubricating performance of oil products by the synergistic effect of high-molecular polymer ester extreme-pressure agents, high-basic sulfonates and sulfur-based extreme-pressure additives

[0007] In addition, Japanese patent JP H10279979A discloses a rust-proof stamping oil without chlorine additives. This patent uses lubricating oil containing potassium borate lubricant as base oil, sulfurized fatty oil as extreme pressure agent, and metal sulfonate and its oxidized derivatives to enhance the antirust effect, however, the kinematic viscosity of the oil introduced in the patent is between 2 and 40mm 2 Within the / S range, the viscosity cannot meet the lubrication requirements when stamping medium and thick plates
