Problems solved by technology

[0005] In view of the defects and deficiencies of the prior art, the object of the present invention is to provide a method for preparing a black phosphorene / graphene oxide composite water-based lubricating additive for titanium alloy cutting and a composite water-based lubricating additive, which cannot be used for a single lubricant. Aiming at the limitations of synergistic lubrication, a composite lubricant is proposed, which aims to solve the problems of poor multifunctionality, oxidation resistance and lubrication failure in traditional titanium alloy machining fluids, improve the tribological properties of metal cutting fluids, and achieve high efficiency of titanium alloys. lubricating

Embodiment 1

[0038] This embodiment proposes a preparation method of black phosphorene / graphene oxide composite water-based lubricating additive, comprising the following steps:

[0039] (1) Preparation of black phosphorene nanosheets: 2 g of red phosphorus powder and stainless steel balls with a diameter of 10-20 mm were added to a ball mill jar according to a ball-to-material ratio of 50:1 and vacuum-sealed. Phosphorus powder. 0.5 g of black phosphorus powder was added to 200 ml of N-methylpyrrolidone solution for 8 hours of ultrasonic treatment in an ice-water bath, and then the resulting solution was centrifuged at 3000 rpm for 20 minutes, and the supernatant was taken out. Subsequently, the supernatant was centrifuged at 11,000 rpm for 30 minutes to obtain a precipitate, which was repeatedly washed with absolute ethanol and dried in vacuum to obtain black phosphorene nanosheets.

Abstract

The invention provides a preparation method of a black phosphorene / graphene oxide composite water-based lubricating additive, and the method comprises the following steps: preparing black phosphorenenanosheets by using a high-energy ball milling and liquid phase stripping method, and ultrasonically dispersing the black phosphorene nanosheets into an aqueous solution through hydroxylation treatment to obtain a black phosphorene water-based dispersion liquid; and uniformly mixing the black phosphorene water-based dispersion liquid with a graphene oxide dispersion liquid through an intermolecular self-assembly effect and introducing sodium dodecyl benzene sulfonate, polyethylene glycol and the like at the same time at high temperature and high pressure for functional synthesis to finally prepare the black phosphorene / graphene oxide composite water-based lubricating additive. The water-based lubricating additive prepared by the invention can replace a traditional oil lubricating additive,can effectively reduce the friction coefficient of a lubricant and improve the wear resistance of metals, is energy-saving and environment-friendly, and can be applied to the field of titanium alloycutting processing.

Description

technical field [0001] The invention belongs to the field of lubricating additives, in particular to a method for preparing black phosphorene / graphene oxide composite water-based lubricating additives. Background technique [0002] Titanium alloy has a series of problems such as low thermal conductivity, high high temperature chemical activity and small elastic modulus, and high processing cost. Lubrication is the main method to solve titanium alloy processing. However, with the increasingly serious global environmental pollution, traditional mineral-based lubricating oil can no longer meet the green production requirements of energy saving and environmental protection. Therefore, it is urgent to develop a water-based composite lubrication with excellent performance. agent. [0003] In modern industry, compared with oil-based cutting fluid, the water content in water-based cutting fluid is as high as 95%, and the content of functional additives is controlled within 5%.
