Embodiment 1

[0016] Add 0.3g of red phosphorus and 0.7g of graphene into a tungsten carbide tank under the protection of nitrogen, seal it and ball mill it at a speed of 300rpm for 16 hours. After the reaction tank is cooled, the red phosphorus / graphene composite (Gr-P) can be obtained . The obtained Gr-P was added to the polyether (PAG) base oil according to the concentrations of 0.1wt%, 0.5wt%, 1wt% and 1.5wt%, respectively, mechanically stirred for 30 min, and then ultrasonicated for 30 min. Dispersion systems with different contents of Gr-P and PAG were obtained.

Embodiment 2

[0018] Add 0.5 g of red phosphorus and 0.5 g of graphene into a tungsten carbide tank under the protection of nitrogen, seal it and ball mill it at 300 rpm for 16 h, and get the red phosphorus / graphene composite (Gr-P) after the reaction tank is cooled . The obtained Gr-P was added into the polyether (PAG) base oil according to the concentrations of 0.1wt%, 0.5wt%, 1wt% and 1.5wt%, respectively, mechanically stirred for 30 min, and then ultrasonicated for 30 min. Dispersion systems with different contents of Gr-P and PAG were obtained.

Embodiment 3

[0020] Add 0.7g red phosphorus and 0.3g graphene into a tungsten carbide tank under the protection of nitrogen, seal it and ball mill it at 300rpm for 16 hours, and get red phosphorus / graphene composite (Cr-P) after the reaction tank is cooled. . The obtained Gr-P was added into the polyether (PAG) base oil according to the concentrations of 0.1wt%, 0.5wt%, 1wt% and 1.5wt%, respectively, mechanically stirred for 30 min, and then ultrasonicated for 30 min. Dispersion systems with different contents of Gr-P and PAG were obtained.

[0021] Structural analysis: the products of Examples 1, 2, and 3 were dispersed in absolute ethanol, and their appearance was determined by JSM-6701F cold field emission scanning electron microscope and JEM-1200EX transmission electron microscope, as shown in the attached figure 1 shown. The results show that the compound formed by bonding red phosphorus and graphene by ball milling method is loose in appearance and thin in thickness, which is benef...

Abstract

The invention discloses a chemically bonded phosphorus / carbon composite and a preparation method and an application thereof. The chemically bonded phosphorus / carbon composite disclosed by the invention is characterized in that in the composite, phosphorus and carbon are bonded through phosphorus-oxygen-carbon covalent bonds, the raw materials include red phosphorus and carbon, and the mass ratio of the red phosphorus to the carbon is 3:7-7:3. The preparation method of the composite is as follows: adding the red phosphorus and the carbon materials in different mass ratios into a ball mill underthe protection of inert gas, sealing, and then performing ball milling for 10 hours at high rotation speed for preparation. The composite is applied as a high-temperature lubricating oil friction-reducing and anti-wear additive and can form a stable dispersion system in polyether (PAG), polyethylene glycol (PEG) and other synthetic lubricating oils and exhibit excellent friction-reducing and anti-wear performance in the temperature range of 50-200 DEG C.

Description

technical field [0001] The invention relates to a chemically bonded phosphorus / carbon compound and a preparation method thereof, as well as the application of the compound as a friction-reducing and anti-wear additive for high-temperature synthetic lubricating oil. Background technique [0002] Many different types of phosphorus-containing compounds have been studied and applied as lubricating oil additives, especially as potential anti-friction and anti-wear additives. Examples include neutral triaryl phosphates, metal-containing dithiophosphates, and phosphorus-containing ionic liquids. However, the traditional method of preparing phosphorus-containing additives is lengthy, polluting, and costly, and these shortcomings need to be further resolved. Contents of the invention [0003] The object of the present invention is to provide a novel solid additive for high-temperature lubricating oil—a chemically bonded phosphorus / carbon composite, which is prepared by ball millin...
