SYNTHETIC LUBRICANT COOLANT WITH CARBON NANOTUBES Russian patent published in 2011 - IPC C10M173/02 C10M125/02 C10M125/10 C10M125/20 C10M133/08 C10M155/02 B82B3/00 

FIELD: chemistry.

SUBSTANCE: lubricant coolant contains the following in wt %: triethanolamine 0.8-1.6, calcined soda 0.25-0.35, sodium nitrite 0.25-0.5, antifoaming additive 0.1-0.08, modifier 0.01-1.0, water - the rest. The modifier is a dispersion aqueous solution of carbon nanotubes in concentration of 170-300 mln/ml, obtained using ultrasound. The degree of dispersion of the solution is preferably 3.5-5.0 mcm. The diametre of the nanotubes is preferably 40-60 nm and the length is not greater than 2 mcm. The antifoaming additive used can be polysiloxane liquid.

EFFECT: improved tribological properties, especially sealing load criterion and high durability of the cutting tool.
