Storage lubricating grease and method for preparing same

Abstract

The invention relates to storage lubricating grease and a method for preparing the same. The storage lubricating grease consist of the following ingredients in part by weight: 1,800 to 2,100 parts of polyalphaolefin, 30 to 40 parts of calcium hydroxide, 50 to 65 parts of 75# ceresine wax, 40 to 60 parts of boric acid, 60 to 80 parts of butyl alcohol / n-butyl alcohol, 70 to 80 parts of 12-hydroxy stearic acid, 40 to 60 parts of purified dimer acid, 40 to 60 parts of glacial acetic acid, 2,000 to 2,500 parts of cleaning agent, 700 to 900 parts of 0.25 percent oil orange and high-viscosity lube base oil, 2,030 parts of diphenylamine and 10 to 20 parts of anti-rusting agent. The preparation method comprises the following steps of: 1, charging; 2, saponifying; 3, performing supplement saponificatio; 4, cooling to reduce temperature; and 5, dewaxing to obtain the finished product of the storage lubricating grease. The storage lubricating grease of the invention can effectively resist corrosion of chemicals, oil, water and gas and avoid affecting rubber and plastics and is applicable to the environment polluted by chemicals, oil or water at extremely high temperature. The deformed steel bars are not rusted under the protection of the storage lubricating grease.

Description

technical field [0001] The invention belongs to the field of lubricating oil, in particular to a storage lubricating grease and a preparation method thereof. Background technique [0002] In my country's infrastructure construction, the demand for threaded steel is increasing, such as: natural gas transportation, crude oil transportation, etc., but in construction, due to the relatively long construction period, threaded steel needs to be stored for a long time. During the storage process, due to storage conditions ( Such as site, natural environment, etc.) cannot meet the requirements, and the corrosion loss of threaded steel is relatively serious. At present, the anti-rust protection products for threaded steel are ordinary anti-rust oils, but for long-term or ultra-long-term storage, ordinary anti-rust oils can no longer meet the requirements of long-term storage and sealing, and new products need to be developed to meet the growing needs.
