Abstract

The invention discloses anti-oxidant lubricating grease, belonging to the technical field of lubricants. The technical scheme of the invention is that the anti-oxidant lubricating grease is prepared from the following raw materials in parts by weight: 10-30 parts of an oligomer of trimethyl dihydroquinazolone, 2-10 parts of isodehydrocostus lactone, 1-6 parts of tetrahydropalmatine, 2-7 parts of sodium dipenta acid, 2-7 parts of bissalicylidene propane diamine, 3-9 parts of p-Hydroxybenzaldehyde, 1-3 parts of methyl citrate, 2-7 parts of chlorinated paraffin, 2-10 parts of diphosphorothioate, 1-3 parts of monoglvceride citrate, 2-5 parts of alkyl succinimide, 1-3 parts of viburnum themoidigenic acid, 1-5 parts of boron nitride, 1-3 parts of oleanonic acid, 2-8 parts of lupeol palmitate and 2-5 parts of polyisobutene. Compared with the prior art, the anti-oxidant lubricating grease disclosed by the invention is simple to prepare, economical and practical and low in cost, can effectively prevent instruments from being damaged, and is high in anti-oxidant performance, long in service cycle, free from any damages to mechanical equipment, and meanwhile has good frictional characteristic, wear resistance and anti-corrosion performance.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to an anti-oxidation grease. Background technique [0002] The current use of grease is due to its specific semi-solid state. Grease is easier to seal into bearings than lubricating oil, and grease can also act as a seal to resist pollution in humid and dusty environments, so the use of grease requires The amount is large. The use of lubricating grease is very wide because of its wide range, so various kinds of grease additives are required to be used in lubricating grease, so as to meet people's requirements for the use of lubricating grease, so the amount of lubricating grease additives is less than that of lubricating oil additives. Big. However, the anti-oxidation function of the existing lubricating grease is not ideal, and the mechanical equipment cannot be fully protected while anti-oxidation. Contents of the invention [0003] The object of the present invention is t...
