Stable machinery lubricating oil

Abstract

Disclosed stable machinery lubricating oil is prepared from the following raw materials in parts by weight: 25-35 parts of sulfurized calcium alkyl phenolate, 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 42-type chlorinated paraffin. The lubricating oil provided by the invention has good high temperature properties with a dropping point more than 235 DEG C, the changed of the denseness of the lubricating oil is not obvious along with the change of temperature, and the lubricating oil is capable of satisfying the usage in a wide temperature scope and has the advantage of being not hardened at high temperature; the lubricating oil is low in cost, has good adhesion property compared with a composite aluminium phase, is improved in extreme pressure properties and load resistance, and therefore the lubricating oil is applicable to lubrication of high-temperature heavy-load apparatus running parts.

Description

technical field [0001] The invention relates to a stable mechanical 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 los...

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 temperatures, generally hardening occurs at 120-150°C), and as the temperature increases, the hardening phenomenon becomes more obvious, often causing the moving parts to be stuck during high-temperature operation. Even cause the moving parts to sinter together, resulting in the shutdown of the equipment

General lubricating oil is difficult to meet the lubrication requirements of heavy-duty equipment, and it is easy to cause lubrication failure
