preparation example Construction

[0034] A preparation method of long-life industrial robot RV reducer grease, comprising the following steps in sequence:

[0035] (1) Mix the fatty acid with part of the base oil and heat it. When the temperature rises to 60-100°C, add dissolved lithium hydroxide and react for 30-90 minutes;

[0036] (2) Continue to heat up at a rate of 0.5-2.0°C. When the temperature rises to 125-175°C, add an antioxidant and react for 10-60 minutes under intermittent stirring.

[0037] (3) Continue to heat up to 180-210°C, react for 1-15min, after the reaction is completed, add the remaining base oil, cool down to 60-100°C, then add extreme pressure anti-wear agent, friction modifier, metal deactivator in sequence , Anti-rust agent, grinding to get grease.

Abstract

The invention provides long-life industrial robot RV reducer lubricating grease and a preparation method thereof. According to the long-life industrial robot RV reducer lubricating grease, synthetic oil is used as base oil, fatty acid lithium soap is used as a thickening agent, an antioxidant, an anti-wear reagent at extreme pressure, a friction modifier, a metal deactivating agent and an antirusting agent are added and the long-life industrial robot RV reducer lubricating grease is prepared through modulation by a special technology, and the thickening agent is a thickening agent generated from the reaction of fatty acid and lithium hydroxide; and the antirusting agent is one type or multiple types of sulfonate, hydroxyl and salts of the hydroxyl, organic amine, esters, organic phosphoricacid and salts of the organic phosphoric acid and a heterocyclic compound. The long-life industrial robot RV reducer lubricating grease has excellent mechanical stability and oxidation stability, excellent abrasion resistance, low-temperature resistance and protection performance. Lubricating requirements of an industrial robot RV reducer are met. According to the preparation method of the long-life industrial robot RV reducer lubricating grease, a certain amount of antioxidant addition agents are added before high-temperature refining to effectively prevent high-temperature oxidation, and the service life of the lubricating grease is prolonged; and petroleum calcium sulfonate is added, and the tribology performance is effectively improved.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a long-life industrial robot RV reducer lubricating grease and a preparation method thereof. Background technique [0002] In recent years, as labor costs continue to rise, the phenomenon of "machine substitution" in the industrial field is common, and the industrial robot market and industry have gradually developed accordingly. As the average salary of employees in urban units in China has soared from 18,200 yuan 10 years ago to 56,399 yuan, under the pressure of high-cost labor, the use of industrial robots to transform intelligent manufacturing has become a development trend, and it is also one of the major strategies of China's manufacturing industry. Industrial robots mainly refer to multi-joint manipulators or multi-degree-of-freedom robots for the industrial field, which are used for handling, welding, assembly, processing, painting, and clean production in the...
