Abstract

The invention discloses improved rail lubricating grease prepared from the following raw materials in parts by weight: 3-9 parts of tetrahydropalmatine, 1-3 parts of potassium dihydrogen phosphate, 2-6 parts of isodehydrocostus lactone, 3-7 parts of oleanonic acid, 1.5-4 parts of oleic acid, 2.5-6 parts of dialkyl calcium benzene sulfonate, 2-4 parts of imidazoline, 4-6 parts of alkylphenol sulfide, 1-5 parts of sodium citrate, 1.5-6 parts of polyacrylate copolymerization emulsion, 1-4 parts of alkyl naphthalene, 6-10 parts of thickening agent and 2-6 parts of extreme-pressure additive. The improved rail lubricating grease disclosed by the invention can form a lubricating layer between a rail and an object to reduce the friction between the rail and the object and prolong the service life of the rail, and has a certain cooling effect at the same time.

Description

technical field [0001] The present invention relates to an improved track grease. Background technique [0002] Grease is usually divided into soap-based grease and non-soap-based grease, of which soap-based grease is the most commonly used grease, whether it is soap-based grease or non-soap-based grease, the grease itself is characterized by changes with temperature, The consistency of lubricating grease changes greatly, especially high-temperature grease. Although it has a high dropping point (dropping point greater than 300°C), as the temperature rises, the lubricating grease becomes soft and loses or becomes hard and coked, and has lost its lubricating effect. General lubricating grease is difficult to meet the lubrication requirements at high temperature, and it is easy to cause lubrication failure. Rails generally carry objects to move, and the friction between rails and objects is generally large. Timely lubrication and cooling are required to reduce the friction bet...
