Embodiment 1～4

[0021] According to the parts by weight in Table 1, weigh the required amounts of antioxidants, extreme pressure agents, and rust inhibitors respectively, add them to 100 parts of base oil, heat and stir at 45-65°C until completely uniform, and obtain a combination thing. The types and amounts of each component in the composition are shown in Table 1 (base oil is omitted), and the properties of the oil (antirust test results) are shown in Table 2.

[0022] Among them, the liquid phase corrosion test is evaluated by GB / T11143 "Test Method for Antirust Performance of Mineral Oil Added Inhibitors in the Existence of Water", and the test conditions are distilled water for 24 hours. The damp heat test is evaluated by GB / T2361 "Damp Heat Test Method for Antirust Grease", the test condition is No. 45 steel sheet, 49±1°C, grade A.

Abstract

The invention relates to use of trimethylolpropane oleate, a trimethylolpropane oleate containing the composition and use of the trimethylolpropane oleate containing the composition. By adding the trimethylolpropane oleate into lubricating oil, not only can excellent antifriction and abrasion resistance be obtained, but also the rust resistance of an oil product can be improved.

Description

technical field [0001] The invention relates to a use of trimethylolpropane oleate, a composition containing the substance and the use. Background technique [0002] Trimethylolpropane oleate has the characteristics of good lubricating performance, high viscosity index, good flame resistance, and a biodegradation rate of over 90%. It is an ester-type fire-resistant hydraulic fluid, as well as hydraulic oil and chain saw oil that require environmental protection. It is an ideal base oil for motor oils used in boats and yachts; at the same time, as an oily additive, it is widely used in industrial lubricants such as spindle oils and spindle oils, as well as metalworking fluids such as rolling oils, drawing oils, and cutting oils. For example, the document CN103614192A discloses a sulfur-containing phosphorus automotive gear lubricating oil, which is characterized in that trimethylolpropane oleate 9134 is used as base oil, polypentasulfide TDPS532, dihydrocarbyl pentasulfide RC...
