Abstract

The invention discloses a method for preparing anti-aging, anti-corrosion and anti-fouling lubricating oil. The method includes dissolving polyaspartic acid into a buffer solution, adding sodium stearate organic modified hydrotalcite, performing ultrasonic dispersion, then performing magnetic stirring, centrifuging and washing, dispersing in a cerium nitrate aqueous solution, performing ultrasonicdispersion, performing magnetic stirring, centrifuging and washing to obtain cerium ion-sodium stearate compound modified hydrotalcite; adding copper chloride dehydrate and polyethylene glycol into deionized water for dissolving, dropwise adding a sodium hydroxide solution and a glucose solution, then adding modified nano-zinc oxide, stirring for reaction, dropwise adding a sodium chloride solution, stirring for reaction at constant temperature, filtering, washing, drying in vacuum and grinding to obtain antifouling microcapsules; mixing nano cerium dioxide and nano serpentine, adding a compound surfactant, carrying out ultrasonic dispersion to obtain a lubricating additive, adding the lubricating additive into lubricating oil base oil, and uniformly mixing with the cerium ion-sodium stearate compound modified hydrotalcite and the antifouling microcapsules to obtain the anti-aging, anti-corrosion and anti-fouling lubricating oil.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and in particular relates to a method for preparing anti-aging, anti-corrosion and anti-fouling lubricating oil. Background technique [0002] Lubricants are made from a blend of base oils and additives, about 95 percent of which are mineral oils derived from petroleum. Mineral lubricants have poor biodegradability, and if they are lost in the environment, they will directly pollute the soil. 1kg of petroleum-based lubricants can pollute 1,000,000L of water. At the same time, due to the decreasing and non-renewable nature of mineral oil, it is imperative to develop environmentally friendly lubricants. Vegetable oil-based lubricants, called "bio-lubricants", are biodegradable, renewable, and non-toxic, and, in addition, have various performance advantages, such as good lubricity, high viscosity index, high flash point, etc. However, vegetable oil base oils have poor oxidation stability. This is due...
