Abstract

The invention provides novel lubricating grease for a railway switch machine and a preparation method. The novel lubricating grease comprises components in parts by mass as follows: 50-60 parts of refined third vacuum side mineral oil, 10-12 parts of 150BS base oil, 10-12 parts of 12-hydroxystearic acid, 2-3 parts of sebacic acid, 2-3 parts of lithium hydroxide monohydrate, 0.5-1 part of calcium hydroxide, 0.5-1 part of diphenylamine, 5-7 parts of ethylene propylene rubber, 2-3 parts of a T202 anti-oxidant, anti-corrosion and anti-wear agent, 6-8 parts of lead naphthenate, 4-6 parts of vulcanized cottonseed oil, 0.05 parts of propionic acid octadecyl ester and 0.1 parts of 2,6-di-tert-butylphenol. The prepared lubricating grease has excellent low-temperature performance, has high-temperature oxidation resistance and seawater corrosion resistance and has an applicable range being subzero 60 DEG C-180 DEG C, thereby being completely capable of meeting the requirements of whole-territorycoverage, all weather operation and all section safety.

Description

technical field [0001] The invention belongs to the field of lubricating grease for switch machines, and in particular relates to a novel lubricating grease for railway turnout switch machines and a preparation method thereof. Background technique [0002] The turnout is the key equipment that determines the train's running route, and the equipment that operates the turnout is the switch machine. The switch machine is installed on the side of the switch point rail or between the rails. The action and display circuit of the switch machine is called the switch control circuit. , it is an important part of the signal circuit. The switch machine is an important signal basic equipment, which is used to realize the switching and locking of the turnout. It is the equipment directly related to the driving safety, and plays a very important role in ensuring the driving safety and improving the transportation efficiency. At present, most of the lubricating greases used for switch mac...
