Problems solved by technology

[0002] In recent years, with the advancement of science and technology, the continuous upgrading of mechanical equipment, environmental protection, energy saving and other issues have attracted much attention, and higher requirements have been put forward for lubricating oils such as gear oil and engine oil. Currently, graphite is used as an additive in the market. The lubricating oil has not undergone desulfurization and desilicate treatment, the residual sulfur in the use process will eventually cause environmental pollution, and the residual silicate will affect the lubrication effect and make the oil quality unstable

Embodiment 1

[0013] Mix 40Kg of expanded graphite and 60Kg of flake graphite to make a material, put the prepared material into a pressure vessel and pressurize it to 5Kg, and after standing still for 30 minutes, align the valve of the pressure vessel with the discharger and open for gas expansion; The puffed mixed material is crushed to a fineness of 3 microns, and then the crushed mixed material is passed through 10 magnetic fields with a magnetic flux of 19,000 gauss, and the frequency of the magnetic field is adjusted to 50 triple harmonics, and the mixed material can be recovered to obtain solid lubrication agent, the solid lubricant and lubricating oil are combined to obtain a new type of lubricating oil. After being applied to automobiles, the fuel saving rate is measured by using the safety routine method. After being applied to the drilling machine, the safety ratio is measured by using the safety method. The fuel saving rate is up to 17%, and the service life of the engine oil is ...

Embodiment 2

[0015] Mix 80Kg of expanded graphite and 20Kg of flake graphite to make a material, put the prepared material into a pressure vessel and pressurize it to 15Kg, and after standing still for 60 minutes, align the valve of the pressure vessel with the discharger and open for gas expansion; The puffed mixed material is crushed to a fineness of 100 microns, and then the crushed mixed material is passed through 20 magnetic fields with a magnetic flux of 14,000 gauss, and the frequency of the magnetic field is adjusted to 150 triple harmonics, and the mixed material can be recovered to obtain solid lubrication Agent, the solid lubricant and lubricating oil are used together. According to the test of the Energy Utilization Monitoring Center of the Ministry of Communications, the automobile torque contrast coefficient Km=1.04, the power contrast coefficient Kp=1.03, and the automobile acceleration performance is improved by 13.6%.

Embodiment 3

[0017] Mix 60Kg of expanded graphite and 40Kg of flake graphite to make a material, put the prepared material into a pressure vessel and pressurize it to 10Kg, and after standing still for 450 minutes, align the valve of the pressure vessel with the discharger and open for gas expansion; The puffed mixed material is crushed to a fineness of 50 microns, and then the crushed mixed material is passed through 15 magnetic fields with a magnetic flux of 16,000 gauss, and the frequency of the magnetic field is adjusted to 100 triple harmonics, and the mixed material can be recovered to obtain solid lubrication Agent, this solid lubricant is matched with lubricating oil, the novel lubricating oil that obtains, and this novel lubricating oil is applied to automobile tail gas carbon monoxide and carbon oxide emission measurement, and the measured result shows that after using the solid lubricant of the present invention, automobile Compared with similar products, the emissions of carbon ...

Abstract

The present invention relates to preparation process of antifriction and anti-fouling solid lubricant, and is especially preparation process of lubricant with graphite as main material and suitable for use in metallurgy, mine, mechanical industry, chemical industry, vehicle, ship, etc. The preparation process includes the following steps: 1. mixing expandable graphite in 40-80 wt% and scale graphite in 20-60 wt%, pressurizing the mixture in some container for 30-60 min and opening the valve to the container for puffing; 2. crushing the puffed mixture to fineness of 3-100 microns; and 3. making the crushed mixture pass through 10-20 magnetic fields of 14-19 kilogauss to obtain the solid lubricant.

Description

technical field [0001] The invention relates to a preparation method of a wear-reducing and antifouling solid lubricant. In particular, a preparation method of a lubricant using graphite as a raw material is suitable for lubricating systems such as metallurgy, mining, machinery, chemical industry, vehicles, and ships.
