Embodiment 1

[0017] Example 1: A lubricating ultra-fine nano-scale iron powder is prepared by the following method. The temperature is controlled at -5°C, and then the iron powder particles are cut at high speed, and the number of high-frequency cutting is set at 5500 per minute. Production of nano-iron powder in the case of the first time, and then high-frequency grinding of the cut iron powder particles at 4000 rpm, sorting out the iron powder particles with a shape of D50=35nm-60nm that are spherical, and using polishing technology The surface of iron powder particles should be polished. In the process of cutting and processing, high-frequency cutting machines, electronic splitters, purification furnaces, nitrogen generators, cyclone classifiers, polishing machines, high-frequency grinding machines and other equipment are used.

Embodiment 2

[0018] Example 2: A lubricating ultrafine nano-scale iron powder is prepared by the following method. The temperature is controlled at -10°C, and then the iron powder particles are cut at high speed, and the number of high-frequency cutting is set at 6000 per minute. Production of nano-iron powder in the case of the second time, and then high-frequency grinding of the cut iron powder particles at 4500 rpm, sorting out the iron powder particles with a shape of D50=35nm-60nm as a global shape, and polishing technology The surface of iron powder particles should be polished.

Embodiment 3

[0019] Example 3: A lubricating ultra-fine nano-scale iron powder is prepared by the following method. The temperature is controlled at -20°C, and then the iron powder particles are cut at high speed, and the number of high-frequency cutting is set at 5700 per minute. Production of nano-iron powder in the case of the second time, and then high-frequency grinding of the cut iron powder particles at 5500 rpm, sorting out the iron powder particles with a shape of D50=35nm-60nm that are spherical, and using polishing technology The surface of iron powder particles should be polished.

Abstract

The invention relates to a method for producing ultra-lubricant nanometer iron powder, wherein it comprises under -10 to -20Deg. C, high-speed cutting the iron powder, while the cutting times is 5700-5900n / min, to product nanometer iron powder, then high-frequency grinding the iron particles at 4500-5500n / min, selecting the iron power in ball shape and 35nm-60nm size, furnishing the surface. The inventive iron powder has high mechanical strength and stable suspension property, etc.

Description

technical field [0001] The invention relates to a production process of superfine nano-scale iron powder, in particular to a super-lubricant nano-scale iron powder. Background technique [0002] "Super lubricant" is also known as "anti-wear agent" in the market. Mainly used in internal combustion engines and mechanical friction equipment, its function is to increase the lubrication function, reduce mechanical wear and prolong mechanical life. At present, the "super lubricants" on the market are basically foreign products. Compared with ordinary lubricants, nano-level bronze powder is added to the "super lubricants". In use, the bronze powder is evenly distributed in the lubricant, so that the machine is evenly spread on the surface of the machine during mutual friction, and the smooth physical properties of the bronze powder are used to form a nano-thick protective layer on the surface of the machine, thereby reducing mechanical friction and prolonging the life of the machi...
