Lightweight, high strength, high reliability and durability have become the development goals of current materials. Titanium alloys are widely used in high-end fields such as aerospace, marine engineering, petrochemicals and weapons and equipment due to their excellent properties such as high strength, good corrosion resistance, high temperature resistance and fatigue resistance. The dimensional accuracy and performance of these workpieces will directly affect the safety and stability of the equipment. In order to obtain these workpieces, R&D personnel have put forward higher requirements for processing technology.

[0003] Titanium alloy is a hard-to-deform alloy. It is difficult to form. It has a large resistance to dislocation movement, poor plasticity, and a large resistance during the forming process, so the forming dimensional accuracy is not high. Stamping oil plays a vital role in the forming process. It not only plays a role in lubrication and anti-wear, but also plays a role in heat dissipation and cooling. At present, there are few stamping oils for titanium alloys on the market.

[0022] The present invention provides a titanium alloy stamping oil composition and a preparation method thereof. In order to make the purpose, technical scheme and effect of the present invention clearer and more specific, the present invention is further described in detail by the following examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] The first aspect of the present invention provides a titanium alloy stamping oil composition, and its preparation raw materials include, by weight: 50 to 80 parts of base oil, 5 to 10 parts of oiliness agent, 5 to 15 parts of extreme pressure anti-wear agent, 0.5 to 1 part of metal corrosion inhibitor, and 0.5 to 2 parts of rust inhibitor; the base oil includes vegetable oil and mineral oil; the mass ratio of the vegetable oil to the mineral oil is (1 to 2):1.

[0024] The titanium alloy stamping oil composition of the present invention has high lubricity, good heat dissipation and extreme pressure and wear resistance, can meet the processing requirements of difficult-to-process titanium alloys, make the workpieces less likely to stick, effectively protect the molds, and extend the service life of the molds. And the surface quality and precision of the processed workpieces can be high. In addition, the titanium alloy stamping oil composition of the present invention is safe and environmentally friendly, and has no harm to the human body.

[0025] The base oil has the highest content in the formula and also determines the cooling and lubricating properties of the stamping oil. The present invention uses vegetable oil and mineral oil to form the base oil, which not only improves environmental safety, but also improves the lubricating properties of the titanium alloy stamping oil composition.

[0026] The mineral oil is selected from narrow distillation range desulfurized mineral oil, and the finished product has high brightness and good heat dissipation performance. Narrow distillation dearomatized mineral oil is non-toxic and odorless. The risk of contact by on-site workers is low and will not threaten their health. Specifically, the mineral oil can be at least one of 200N, 250N, and 300SN.

[0031] Extreme pressure anti-wear agents form an oil film with stronger load-bearing capacity under harsh processing conditions to block the contact between workpieces, thereby reducing surface roughness. For difficult-to-process titanium alloys, the lubricity of extreme pressure anti-wear agents is particularly critical. The extreme pressure anti-wear agent used in the present invention can give the titanium alloy stamping oil composition good extreme pressure anti-wear performance, and can provide extreme pressure lubrication under harsh processing conditions. In this embodiment, the present invention uses a phosphorus extreme pressure anti-wear agent and a sulfur extreme pressure anti-wear agent for compounding, so that the titanium alloy stamping oil composition can achieve the best lubrication effect.

[0032] Preferably, the phosphorus-based extreme pressure anti-wear agent is at least one of triphenylthiophosphate, acidic phosphate ammonium salt, trilauryl phosphate, dioleyl phosphite, and tetradecyl phosphate.

[0033] Preferably, the sulfur-based extreme pressure anti-wear agent is at least one of sulfurized olefins, sulfurized lard, sulfurized fatty acid methyl ester, and sulfurized polyester.

[0034] Preferably, the rust inhibitor includes at least one of sodium quinic acid, organic polycarboxylic acid, zinc cyclohexane, oleoyl sarcosine, barium petroleum sulfonate, and isomeric nonylphenoxyacetic acid.

[0035] A second aspect of the present invention provides a method for preparing a stamping oil, which is used to prepare the titanium alloy stamping oil composition as described above, comprising the following steps:

[0078] Comparative Example 4

[0079] A titanium alloy stamping oil composition, which differs from Example 1 in that the base oil is a mixture of palm oil and 250N in a mass ratio of 3:1.

[0080] The various properties of the titanium alloy stamping oil compositions of the above embodiments and comparative examples were tested.

[0081] Among them, the lubrication performance test is carried out in accordance with "GB / T 12583-1998 Lubricant Extreme Pressure Performance Determination Method".

[0082] The friction and wear performance test was carried out in accordance with "NB / SH / T 0847-2010 Determination of Friction and Wear Performance of Extreme Pressure Lubricating Oil - SRV Testing Machine Method".

[0083] The wear volume and surface roughness were measured by white light interferometry.

[0084] The test method of lubrication performance is as follows: use the RCP oscillating friction and wear tester, open the special control software of the oscillating friction and wear tester, adjust the frequency to 0.67Hz, the load to 2kg, the cycle time to 6s, and perform 4 cycles of testing; set the preset temperatures of 25℃, 35℃, 45℃ and 55℃, and after heating to the preset temperatures, drip the oil sample on the surface of the stainless steel ball to start the test; measure the friction coefficient between the stainless steel ball and the titanium alloy plate, and record the data on the computer.

[0085] The corresponding test results are as follows:

[0086] Table 1

[0087]

[0088]

[0089] Table 2

[0090]

[0091] Combining Table 1, Table 2 and Figure 1 It can be seen that the titanium alloy stamping oil compositions provided in Examples 1-5 all have excellent lubrication and heat dissipation properties. The titanium alloy stamping oil compositions have low friction coefficients, small wear volumes, and low surface roughness in the tests. Figure 1 It can be seen from the test results that the friction coefficient of the titanium alloy stamping oil composition provided by the present invention is small and meets the use requirements.

[0092] Further comparison of Examples 1-3, Example 4 and Example 5 revealed that when the mass ratio of the phosphorus-based extreme pressure anti-wear agent and the sulfur-based extreme pressure anti-wear agent was greater than or less than the range claimed for protection by the present invention, the various test performances of the titanium alloy stamping oil composition were significantly reduced, reflecting that a specific ratio of phosphorus-based extreme pressure anti-wear agents and sulfur-based extreme pressure anti-wear agents can effectively improve the performance of the titanium alloy stamping oil composition.

[0093] Compared with Examples 1-5, the titanium alloy stamping oil composition of Comparative Example 1 has a base oil in which the mass ratio of vegetable oil to mineral oil is less than the range claimed for protection by the present invention. From the test results, its lubricity, wear scar size and wear volume are significantly reduced compared with Examples 1-5, indicating that the use of vegetable oil and mineral oil in a specific ratio range can effectively improve the performance of the titanium alloy stamping oil composition.

[0094] Comparative Examples 2 and 3 are other types of stamping oils available on the market. From the test results, their test results in terms of lubricity, wear volume, surface roughness, etc. are not as good as those of Examples 1-5.

[0095] Compared with Examples 1-5, the titanium alloy stamping oil composition of Comparative Example 4 has a mass ratio of vegetable oil to mineral oil that is greater than the range claimed for protection by the present invention. From the test results, its lubricity data is slightly worse than those of Examples 1-3 and 5, and is equivalent to Example 4, but the wear marks are larger, which has a relatively greater impact on the processing accuracy of the titanium alloy.

[0096] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the claims attached to the present invention.
