example 1

[0022] Weigh 10g of molybdenum disulfide passed through a 200-mesh sieve, 3.0g of sodium cholate, add 2.0L of deionized water, and disperse in a 40°C constant temperature water bath for 6 hours with a 400W ultrasonic wave to obtain a molybdenum disulfide dispersion. Transfer the dispersion into a centrifuge, centrifuge at 3000r / min for 20min, collect the supernatant, and then centrifuge the supernatant at 12000r / min for 30min to obtain molybdenum disulfide with a two-dimensional layered structure. Molybdenum disulfide was added to 500mL deionized water, cleaned with 300W ultrasonic wave for 20 minutes, and then centrifuged at 12000r / min for 30 minutes to obtain a precipitate. Repeat the ultrasonic cleaning of the precipitate twice to obtain pretreated two-dimensional layered structure molybdenum disulfide. Measure 30mL of silane coupling agent KH-550, 150mL of absolute ethanol, add 0.6L of deionized water, and keep stirring and hydrolyzing at 300r / min for 8 hours in a constant ...

[0024] Weigh 11 molybdenum disulfide and 3.3 sodium cholate that have passed through a 200-mesh sieve, add 2.2 parts to deionized water, and disperse with 400W ultrasonic wave for 7 hours under a constant temperature water bath at 45°C to obtain a molybdenum disulfide dispersion. Dilute the molybdenum disulfide dispersion Transfer to a centrifuge, centrifuge at 3500r / min for 25min, collect the supernatant, and then centrifuge the supernatant at 12250r / min for 35min to obtain molybdenum disulfide with a two-dimensional layered structure. Molybdenum was added to 550mL deionized water, ultrasonically cleaned with 300W ultrasonic wave for 25min, and then centrifuged at 12250r / min for 35min to obtain a precipitate, and the precipitate was repeatedly ultrasonically cleaned twice to obtain pretreated two-dimensional layered molybdenum disulfide. Add 45mL of silane coupling agent KH-550 and 225mL of absolute ethanol to 0.9L of deionized water, and keep stirring and hydrolyzing at 350r / ...

[0026]Weigh 12g of molybdenum disulfide passed through a 200-mesh sieve, 3.6g of sodium cholate, add 2.4L of deionized water, and disperse with 400W ultrasonic wave for 8 hours under a constant temperature water bath at 50°C to obtain a molybdenum disulfide dispersion. Transfer the dispersion into a centrifuge, centrifuge at 4000r / min for 30min, collect the supernatant, and then centrifuge the supernatant at 12500r / min for 40min to obtain molybdenum disulfide with a two-dimensional layered structure. Molybdenum disulfide was added to 600mL deionized water, cleaned with 300W ultrasonic wave for 30 minutes, and then centrifuged at 12500r / min for 40 minutes to obtain a precipitate. Repeated ultrasonic cleaning of the precipitate three times to obtain pretreated two-dimensional layered structure molybdenum disulfide. Measure 60mL of silane coupling agent KH-550, 300mL of absolute ethanol, add 1.2L of deionized water, and keep stirring and hydrolyzing at 400r / min for 10h in a consta...

Abstract

The invention discloses an epoxy resin-based composite wear-resistant coating material and a preparation method thereof, and belongs to the technical field of a composite material. The preparation method comprises the following steps: stripping a molybdenum disulfide crystal in a surfactant aqueous solution according to an ultrasonic auxiliary stripping method to prepare two-dimensional layered structure molybdenum disulfide; modifying with silane hydrolysate; preparing polyurethane prepolymer by taking diisocyanate and polyether glycolas raw materials; finally, compounding epoxy resin, the polyurethane prepolymer, silicon carbide, the molybdenum disulfide and the like to prepare the epoxy resin-based composite wear-resistant coating material. The prepared two-dimensional layered structure molybdenum disulfide is used for forming a low-shear-stress film on the friction surface, so that the friction coefficient is reduced, and filling and repairing effects on the friction surface are achieved; under the synergism of the wear-resistant filler, the wear resistance of the epoxy resin is improved. The epoxy resin-based composite wear-resistant coating material prepared by the method has high tensile strength and high shear strength, has high adhesion property with a base layer, and can meet the requirements of the domestic market.

Description

technical field [0001] The invention discloses an epoxy resin-based composite wear-resistant coating material and a preparation method thereof, belonging to the technical field of composite materials. Background technique [0002] In chemical industry, water conservancy, electric power and other industrial production, the abrasive particles produced by liquid and gas entraining solid particles have serious erosion and wear on equipment. In order to solve the problem of equipment wear and prolong the service life of equipment, at present, it is mainly through the use of expensive wear-resistant alloy pumps, or lining ceramics, rubber, polyurethane, ultra-high molecular polyethylene, composite wear-resistant coating materials, etc., but wear-resistant alloy pumps Wear is still very serious under many conditions of use, and the wear resistance of lining ceramics, rubber, polyurethane, ultra-high molecular polyethylene, etc. is not satisfactory. [0003] Composite wear-resistan...
