Title:
水系潤滑剤及びその製造方法
Document Type and Number:
Japanese Patent JP6813230
Kind Code:
B2
Abstract:
A water-based lubricant and a preparation method therefor. Said method comprises: carrying out an epoxide ring-opening reaction of rubber seed oil and epichlorohydrin, and carrying out a ring-closing reaction under the action of sodium hydroxide and calcium oxide, so as to obtain a rubber seed oil-based epoxy; carrying out a ring-opening reaction of the rubber seed oil-based epoxy obtained in the first step with an alcohol amine compound in an inert organic solvent, so as to obtain a rubber seed oil-based polyolamine; carrying out an esterification reaction of an alcohol or alcohol ether and the rubber seed oil-based polyolamine with a phosphoryl chloride compound in an inert organic solvent, so as to obtain a rubber seed oil-based extreme pressure alcohol or a rubber seed oil-based extreme pressure ether; and dissolving the rubber seed oil-based extreme pressure alcohol or the rubber seed oil-based extreme pressure ether in an aqueous solution of a cellulose derivative, and obtaining, using the interaction of hydrogen bonds, a stable, green and environmentally friendly water-based lubricant. Said water-based lubricant has multiple effects of lubricity, environmental protection and extreme pressure wear resistance.
