Problems solved by technology

At present, the general-purpose high-temperature lubricating oils usually include composite aluminum-based lubricating oils and urea-based lubricating oils. Among them, the composite aluminum-based lubricating oils soften and lose at high temperatures, causing equipment lubrication failure; while urea-based lubricating oils harden at high temperatures (according to different The urea-based grease has different hardening temperat...

Embodiment 1

[0010] The invention is an improved stable lubricating oil, which is made of the following raw materials in parts by weight:

[0011] 30 parts of methyl acrylate, 0.8 parts of nitroglycerin, 4 parts of glyceryl trilinoleate, 5 parts of sorbitol, 7 parts of phosphate triester and 6 parts of trimethyldecane.

Embodiment 2

[0013] The invention is an improved stable lubricating oil, which is made of the following raw materials in parts by weight:

[0014] 25 parts of methyl acrylate, 0.5 parts of nitroglycerin, 2 parts of glyceryl trilinoleate, 2 parts of sorbitol, 3 parts of phosphate triester and 5 parts of trimethyldecane.

Embodiment 3

[0016] The invention is an improved stable lubricating oil, which is made of the following raw materials in parts by weight:

[0017] 35 parts of methyl acrylate, 1 part of nitroglycerin, 6 parts of glyceryl trilinoleate, 7 parts of sorbitol, 8 parts of phosphate triester and 10 parts of trimethyldecane.

[0018] The lubricating oil of the present invention has good high-temperature performance, the dropping point is greater than 235°C, the change of its consistency with temperature is not obvious, it can be used in a wide temperature range, it has the advantage of not hardening at high temperature, and at the same time it is low in cost. It also has good adhesion, and improves the extreme pressure performance and load bearing capacity; therefore, the lubricating oil of the present invention can be used for lubricating the moving parts of high-temperature and heavy-duty equipment.

Abstract

The invention discloses improved stable type lubricating oil. The improved stable type lubricating oil is prepared from the following raw materials in parts by weight: 25-35 parts of methyl acrylate, 0.5-1 part of nitroglycerin, 2-6 parts of trilinolein, 2-7 parts of sorbitol, 3-8 parts of phosphotriester and 5-10 parts of trimethyl decane. The lubricating oil disclosed by the invention has good high-temperature performance, a dropping point greater than 235 DEG C, and unobvious thickness changes with temperature changes, can satisfy use in a wide temperature range, and has the advantage of being not cured at a high temperature; meanwhile, the improved stable type lubricating oil is low in cost, has good adhesiveness in comparison with composite aluminum, and improves extreme pressure property and load resistance, and therefore, the lubricating oil disclosed by the invention can be used for lubricating operation parts of a high-temperature heavy-load device.

Description

technical field [0001] The invention relates to an improved stable lubricating oil, which belongs to the field of industrial chemical industry. Background technique [0002] Lubricating oil is usually divided into soap-based lubricating oil and non-soap-based lubricating oil, among which soap-based lubricating oil is the most commonly used lubricating oil, whether it is soap-based grease or non-soap-based grease, the characteristic of lubricating oil itself is that it changes with temperature, The consistency of lubricating oil changes greatly, especially high-temperature grease. Although it has a high dropping point, as the temperature rises, the lubricating oil becomes soft and loses or becomes hard and coked, and has lost its lubricating effect. At present, the general-purpose high-temperature lubricating oils usually include composite aluminum-based lubricating oils and urea-based lubricating oils. Among them, the composite aluminum-based lubricating oils soften and lose...
