Embodiment 1

[0026] 0.05 kg of nano-graphite, 0.7 kg of sodium dodecylbenzenesulfonate, 0.125 kg of sodium bicarbonate, 0.125 kg of potassium persulfate, 18 kg of methyl acrylate, 1.8 kg of OP-10, and 79.2 kg of water.

[0027] The preparation method of the nano-graphite water-based cutting fluid additive adopts the following steps:

[0028] (a) Ultrasonic dispersion pretreatment: Take nano-graphite, sodium dodecylbenzenesulfonate, sodium bicarbonate, OP-10 and water according to the above weight and carry out ultrasonic dispersion on an ultrasonic processor for 12 minutes;

[0029] (b) Preparation of nano-graphite water-based dispersion: uniformly mix the treatment solution obtained in step (a) with methyl acrylate and initiator potassium persulfate, and react at 65°C for 6 hours;

[0030] (c) Centrifugal purification: centrifuge the nano-graphite water-based dispersion obtained in step (b) at 2000r / min for 35 minutes in a centrifuge, and take the supernatant to obtain the nano-graphite di

Abstract

The invention relates to an additive and a preparation method thereof, in particular to a nanographite additive for water-based cutting fluid and a preparation method thereof. The nanographite additive for the water-based cutting fluid is characterized by comprising the following components in percentage by weight: 0.01-0.10% of nanographite, 0.15-1.20% of sodium dodecyl benzene sulfonate, 0.10-0.15% of sodium bicarbonate, 0.10-0.15% of potassium peroxydisulfate, 15-20% of methyl acrylate, 1.50-2.15% of OP-10, and the balance of water. The nanographite additive for the water-based cutting fluid and the preparation method thereof, provided by the invention, have the beneficial effects that stable diffusion of the nanographite in a water-based medium is realized, and by taking the nanographite as the additive for the water-based cutting fluid, the frictional wear behavior of mechanical parts can be obviously improved, and the lubricating performance of the water-based cutting fluid is enhanced.
