Embodiment 1

[0028] A kind of preparation method of modified nano-additive, concrete steps are as follows:

[0029] 1) Preparation of silane coupling agent hydrolysis base fluid

[0030] Take 20ml of deionized water, add dropwise 0.2g of silane coupling agent (A-151) into the deionized water for hydrolysis, and react for 15min to obtain the hydrolysis base solution.

[0031] 2) Preparation of hexagonal boron nitride-vinyltriethoxysilane

[0032] Take 2g of hexagonal boron nitride in the silane coupling agent hydrolysis base solution, stir in a constant temperature magnetic stirrer for 20 minutes, ultrasonically treat in an ultrasonic cleaner for 20 minutes, pour into a petri dish, and carry out in a vacuum dryer at 100°C drying, using a planetary ball mill for 30 minutes, washing, filtering, and drying at 60°C to obtain hexagonal boron nitride-vinyltriethoxysilane nano additives.

Embodiment 2

[0034] Example 1 Application of modified nano additives in lubricating oil, put modified hexagonal boron nitride into a beaker filled with paraffin wax and deionized water layered up and down. Put unmodified hexagonal boron nitride into a beaker filled with paraffin wax and deionized water layered up and down, as a control.

[0035] Such as figure 1 and 2 As shown, the upper layer of the solution contained in the beaker is paraffin, and the lower layer is deionized water. figure 1 It can be seen that unmodified hexagonal boron nitride is distributed in deionized water, exhibiting hydrophilicity, by figure 2 It can be seen that the modified hexagonal boron nitride is distributed in paraffin wax, showing lipophilic and hydrophobic properties.

Embodiment 3

[0037] The application of embodiment 1 modified nano additives in lubricating oil, add 0.1g hexagonal boron nitride-vinyltriethoxysilane nano additives in 9.9g castor oil, stir 20min in constant temperature magnetic stirrer, and in 60 Ultrasonic treatment at ℃ for 1 h, and standing for 24 h to obtain 1 wt% nanofluid.

Abstract

The invention discloses a modified nano-additive and an application thereof in lubricating oil. A preparation method of the modified nano-additive comprises the following steps: 1) dropwise adding a silane coupling agent A-151 to deionized water, and performing a hydrolysis reaction for 15-20 min to obtain a silane coupling hydrolysis base solution; 2) adding hexagonal boron nitride to the silanecoupling agent hydrolysis base solution, performing magnetic stirring at a constant temperature for 15-30 min, then performing ultrasonic treatment for 15-30 min, performing vacuum drying in a vacuumdryer, performing ball milling for 30 min, washing and filtering the obtained material, and dry the filtered material at 60 DEG C to obtain the hexagonal boron nitride-vinyltriethoxysilane-based nano-additive. The modified nanometer hexagonal boron nitride is lipophilic and hydrophobic, can be stably dispersed in the lubricating oil, can significantly regulate the viscosity of the lubricating oilafter being added to castor oil, and can regulate the corresponding viscosity according to working conditions in order to show excellent friction and wear resistance.

Description

technical field [0001] The invention relates to a modified nanometer additive and its application in lubricating oil. Background technique [0002] In today's industrialization process, the operation of various machinery is bound to be accompanied by the friction and wear of mechanical parts, resulting in a decrease in mechanical life and energy loss. Therefore, how to improve the life of components and reduce energy consumption has become a hot topic. As an effective way to solve friction and wear, lubrication has a long research history. However, with the rapid development of machinery and industrial equipment, traditional oil bodies have been difficult to meet today's lubrication needs. The application of nano-additives in lubrication systems is a new field of development, and many researchers have conducted research on nano-additives. Nano-hexagonal boron nitride belongs to two-dimensional structure nanoparticles and has excellent lubricating properties, so many resear...
