Compound lubricating grease and preparation method of compound lubricating grease

Abstract

The invention relates to lubricating grease, in particular to a compound lubricating grease and a preparation method of the compound lubricating grease. The compound lubricating grease is prepared by castor oil, pentaerythritol ester, stearic acid, Songhua stone powder, nanometer titanium powder, vaseline, benzoic acid, an antioxidant, an anti-wear agent and an antirust agent in determined proportions. The preparation method comprises steps as follows: adding the castor oil and the pentaerythritol ester into a reaction kettle for heating, adding the stearic acid, the Songhua stone powder, thenanometer titanium powder, the vaseline and the benzoic acid, melting and stirring uniformly; refining under a heating and low-speed stirring condition; then cooling, adding antioxidant T501, anti-wear agent T305 and antirust agent T705 in turns under the stirring condition, stirring uniformly; stopping heating, continuing to stir at low temperature, naturally cooling and then packaging separately. The compound lubricating grease has the characteristics of being degradable and beneficial to environmental protection, being low in cost and better in use performance.

Description

[0001] technical field [0002] The invention relates to a lubricating grease, that is, a composite lubricating grease and a preparation method thereof. Commodity name: Batu brand 2012 type open gear grease. Background technique [0003] In the prior art, lubricating grease involves many fields and has a wide range of applications. The main disadvantages of similar products are: 1. Most of them use mineral oil as base oil. Mineral oil is a non-renewable fossil energy, the resource is on the verge of exhaustion and seriously pollutes the environment. 2. The applicable temperature range is small. At present, the applicable temperature of similar products is generally in the range of -20°C to 120°C, and they cannot be used in many cases. 3. Strong smell. During use, it will cause headaches, nausea, and blurred vision of the operator, which is harmful to health. 4. The price is high. The rising price of fossil energy has increased the production cost and use cost of enterpr...
