However, graphene sheets do not contain other active functional groups, and there is a strong van der Waals force between the sheets, so it is easy to superimpose, making it difficult to exert its excellent performance.
[0004] Most commercially available lubricating oils have the defects of poor thermal insulation performance and poor wear resistance. The present invention provides a method for modifying lubricating oil for heat insulation and wear resistance. The lubricating oil prepared according to the method provided by the present invention has excellent thermal insulation properties. Thermal insulation performance and wear resistance

Abstract
The invention discloses a thermal insulation and wear resistance modification method of lubricating oil. The thermal insulation and wear resistance modification method of the lubricating oil comprisesthe following steps: placing aluminium silicate fibers subjected to pretreatment into a mould, conducting pressing to eliminate air, adding silicon dioxide sol for mixing, standing to form gel, displacing water and alcohol with a n-hexane solution, then adding a trimethylchlorosilane aqueous solution, and conducting hydrophobic treatment to obtain an aluminium silicate fiber-silicon dioxide gel compounded thermal-insulation component; adjusting a pH value of ethanol water by means of acetic acid, adding a silane coupling agent, conducting magnetic stirring and prehydrolysis, then adding potassium hexatitanate whiskers for even mixing, after ultrasonic dispersion is conducted, standing, and conducting vacuumizing and drying to obtain a wear-resistant component, namely, surface-modified potassium hexatitanate whiskers; and adding organosilane-modified graphite oxide into liquid paraffin, then adding the aluminium silicate fiber-silicon dioxide gel compounded thermal-insulation componentand the wear-resistant component, namely the surface-modified potassium hexatitanate whiskers, and conducting even ultrasonic dispersion to produce the lubricating oil subjected to thermal insulationand wear resistance modification.
Description
technical field [0001] The invention belongs to the field of lubricating oil, and in particular relates to a heat-insulating and wear-resistant modification method of 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, which is due to th...
