preparation example Construction
[0035] A preparation method of nanomaterial lubricating oil, comprising the following steps:
[0036] Step 1: Surfactant with mass percentage of 2.0~10.0% and auxiliary agent with mass percentage of 4.0~10.0%
[0037] After the auxiliary additives are mixed, place them in an electric heating constant temperature water bath and stir for 5-8 minutes to obtain a mixed solution;
[0038] Step 2: Adding mass percent to the mixed solution is 1.0-3.0% of nano-graphite particles, the mass percent is
[0039] 0.5-2.0% of nano-molybdenum disulfide particles and 3.0-6.0% of nano-metal copper particles by mass percentage, and continue
[0040] Stir for 10-15 minutes;
[0041] Step 3: After adding the mixture obtained in Step 2 to the base oil, use an ultrasonic oscillator to vibrate, vibrate
[0042] The time is 10-25 minutes;
[0043] Step 4: Put the oscillated oil into a constant temperature magnetic stirrer and stir for 60-90 minutes;
[0044] Step 5: Repeat Step 3 and Step 4 for ...
Embodiment 1
[0048]Mix 4.5% surfactant with 6.0% mass percentage of auxiliary additives and put them into an electric heating constant temperature water bath with a water bath temperature of 70°C and stir for 8 minutes to obtain a mixed solution. Add 1.3% by mass to the mixed solution % of nano-graphite particles, 1.6% by mass percent of nano-molybdenum disulfide particles and 3.0% by mass percent of nano-metal copper particles, and continue to stir for 12min, then add the resulting mixture to the base oil and vibrate with an ultrasonic oscillator , oscillated for 18 minutes, then put the oscillated oil into a constant temperature magnetic stirrer with a working temperature of 75°C, stirred at a speed of 1300r / min for 80 minutes, repeated 3 times of oscillating and stirring the oil to obtain the finished lubricating oil.
Embodiment 2
[0050] Mix 3.0% surfactant with 7.0% mass percentage of auxiliary additives and put them into an electric heating constant temperature water bath with a water bath temperature of 70°C and stir for 8 minutes to obtain a mixed solution. Add 1.2 mass % to the mixed solution % of nano-graphite particles, 0.5% by mass percent of nano-molybdenum disulfide particles and 4.0% by mass percent of nano-metal copper particles, and continue to stir for 12 minutes, then add the resulting mixture to the base oil and vibrate with an ultrasonic oscillator , oscillated for 18 minutes, then put the oscillated oil into a constant temperature magnetic stirrer with a working temperature of 75°C, stirred at a speed of 1300r / min for 80 minutes, repeated 3 times of oscillating and stirring the oil to obtain the finished lubricating oil.
