Embodiment 1

[0057] A kind of selenium ion embedding method of oil phase graphene of the present invention, comprises the steps:

[0058] 1. Put 100g of natural flake graphite powder and 10g of selenium material into two different molybdenum boat vessels respectively, and put them into a vacuum reactor to evacuate to a pressure of negative two atmospheres to negative five atmospheres;

[0059] 2. Using a high-frequency heating method to heat the temperature in the vacuum reactor to 900 degrees Celsius-1100 degrees Celsius, so that the selenium ions in the selenium material are sublimated to the natural flake graphite powder to form selenium ion graphite powder;

[0060] 3. After the selenium ion graphite powder is cooled, add the selenium ion graphite powder into the base oil to peel off the oil-phase graphene to obtain the oil-phase graphene embedded with selenium ions.

[0061] Applying the product in this embodiment to the actual automobile lubrication process, in the emission detection...

Abstract

The invention discloses a selenium-ion inlaying method for oil-phase graphene. The selenium-ion inlaying method comprises the following steps: respectively placing natural flake graphite powder and aselenium material into two different molybdenum boat vessels, placing the vessels into a vacuum reaction kettle, and carrying out vacuumizing; heating the vacuum reaction kettle through a high-frequency heating method, allowing selenium ions in the selenium material to be sublimated onto the natural flake graphite powder so as to form a selenium-ion graphite powder; and after the selenium-ion graphite powder is cooled, adding the selenium-ion graphite powder into base oil for stripping of oil-phase graphene so as to obtain selenium-ion inlaid oil-phase graphene. According to a scheme of the invention, the selenium ions are sublimated onto the natural flake graphite powder as infiltration of a coating film; after completion of infiltration, an oil-phase graphene stripping process is performed, so selenium-ion inlaid graphene is obtained; and the selenium-ion inlaid graphene is added into engine oil, so a lubricating effect can be achieved, and the effects of cooling an engine and savingoil can be achieved.

Description

technical field [0001] The invention relates to the technical field of graphene, in particular to a selenium ion embedding method of oil-phase graphene. Background technique [0002] Selenium is one of the scattered non-metals. Crude selenium is a by-product in the copper smelting process. The growth of selenium production has been relatively slow, and the annual supply is limited. Selenium has a wide range of uses and can be used in many fields such as metallurgy, glass, ceramics, electronics, solar energy, feed, etc., and with the development of the world economy and the emergence of new application fields, the downstream demand for selenium is constantly increasing. The price of selenium is constantly rising. However, as the price of selenium continues to rise, its downstream consumption structure will continue to adjust to adapt to price changes. It is expected that the profit margin of traditional selenium products will remain at a moderate level, while the profit marg...
