Embodiment 1

[0016] Example 1 Prepare a sample of nanometer thorium oxide and nanometer zinc oxide 5:3. 5 parts of nano-thorium oxide and 3 parts of nano-zinc oxide. 100 parts of castor oil, 20ml of acetic acid, 6 parts of ion exchange resin, 30ml of hydrogen peroxide, 5 parts of activated silica powder, 1 part of p-diphenylamine, 0.4 parts of DL171 coupling agent, sodium alkylbenzenesulfonate (LAS) surface active 0.3 parts of agent, 0.2 parts of polyisobutylene (PIB) viscosity index modifier.

[0017] Step 1. Add 100 parts of castor oil, 20ml of acetic acid, and 6 parts of cation exchange resin into a 1000mL three-neck flask, raise the temperature of the oil bath and start magnetic stirring (weigh 30ml of hydrogen peroxide in a separatory funnel). Raise the temperature to a constant temperature of 80°C, slowly add hydrogen peroxide dropwise during the heating process, control the dropping speed so that the addition is completed in about 3 hours, react for about 7 hours, stop the magnetic...

Abstract

The invention discloses a nano modified material contained plant oil based lubricating oil preparation method. According to the method, plant oil synthesized lubricating oil which contains modified materials such as nano thorium nitrate is prepared from castor oil, nano thorium oxide, nano zinc oxide, surfactant sodium alkyl sulfate, ion exchange resin and the like by modification means of acid treatment, coupling, magnetic stirring, microwave treatment and the like.

Description

technical field [0001] The invention relates to a preparation method of vegetable oil-based lubricating oil containing nano-modified materials, and belongs to the technical field of lubricating oil. Background technique [0002] At present, the vast majority of lubricating oils use mineral oil as the base oil. Mineral oil is extracted from petroleum, and its main component is a mixture of hydrocarbon molecules composed of two elements, carbon and hydrogen. Because of its low price and performance that can meet the lubrication needs of most machinery and equipment, it occupies a dominant position in the market. However, in some special occasions, such as hydraulic oil, chain saw oil, outboard two-stroke engine oil and open gear oil and other open systems or disposable circulation systems, due to transportation, leakage, splashing, natural replacement and other reasons, lubrication Oil will inevitably be discharged directly into the environment, especially in sensitive areas...
