Abstract

The invention discloses a method for modifying a water-based lubricating fluid with wood flour-soybean lecithin. The method comprises the following steps: putting wood flour into a high-speed mixer, adding KH550 for treatment, adding a potassium hydroxide solution, stirring, standing, washing with water to neutrality, drying, and pulverizing to obtain composite modified wood flour; heating soybeanlecithin, introducing nitrogen gas, stirring, adding lactic acid and hydrogen peroxide, and reacting at constant temperature to obtain hydroxylated modified soybean lecithin; adding dispersing agentlauryl sodium sulfate into deionized water, heating, stirring and dissolving, adding antirust agent triethanolamine, antifoaming agent dimethicone, the composite modified wood flour and the hydroxylated modified soybean lecithin under thermal insulation conditions, carrying out strong stirring, adjusting the pH value, adding ferrous carbonate, polyhydroxylation modified graphene oxide and surfacemodified carbon fibers, carrying out strong stirring for surface modification and dispersion, and carrying out ultrasonic oscillation in a water bath to obtain the water-based lubricating fluid.

Description

technical field [0001] The invention belongs to the field of lubricating fluids, and in particular relates to a method for modifying water-based lubricating fluids with wood flour-soybean lecithin. Background technique [0002] As a common failure mode of metal materials, wear and tear not only shortens the service life of metal parts, but also causes waste of resources and energy, and brings immeasurable national economic losses. Therefore, it is of great significance to improve the wear resistance of metal materials. [0003] Due to the increasingly serious environmental pollution problems, energy saving, emission reduction and clean production have become the challenges faced by the steel industry. [0004] important question. The oil-based lubricating fluid used in the production process of strip steel produces sludge that is difficult to handle, pollutes water resources, produces a large amount of soot and pollutes the air environment, and seriously endangers the heal...
