Embodiment 1

[0025] Firstly, the technology reported by Liu Zhijie, Zhao Bin and others was used in the document "Chemical Bulletin" No. 10, 1996, pages 55-58, to prepare 100 grams of polymer aqueous dispersion containing 1 gram of nano-spherical copper powder; the content of polymer protective agent PVP It is 16g / L, and the reaction time is 15 minutes.

Embodiment 2

[0027] Referring to Example 1, 100 grams of aqueous dispersion of 1 gram of nano-copper was prepared, and mixed with 6 grams of phosphobisoctyl zinc salt and 100 grams of xylene as a solvent at 65° C. while stirring. The reaction time is 20 minutes, the oil-water phase of the reaction product is separated, and the oil phase is subjected to vacuum distillation to obtain the oil-soluble light-colored nano-copper preparation.

[0028] The particle size of the prepared preparation was tested by a laser particle size analyzer, and the average particle size of the particles was less than 10nm.

[0029] Particle size distribution see figure 1 , see electron microscope photo figure 2 .

Embodiment 3

[0031] With reference to Example 1, prepare 100 grams of aqueous dispersion of 1 gram of nano-copper, mix it with 7 grams of aqueous zinc stearate and 100 grams of solvent undecane under the condition of stirring at 70 ° C, and the reaction time is 30 minutes. The product oil-water phase is separated, and the oil phase is subjected to vacuum distillation. The said oil-soluble light-colored nano-copper preparation can be obtained.

Abstract

The invention discloses an oil-soluble light-colored nano copper preparation as well as a preparation method and application thereof. The preparation method comprises the following steps: (1) mixing water dispersion liquid of nano copper with organic zinc salt and a solvent to obtain light-colored nano copper liquid; (2) performing oil-water separation on a product in the step (1), collecting an oil phase, performing reduced pressure distillation, and separating the organic solvent to obtain the oil-soluble light-colored nano copper preparation. The oil-soluble light-colored nano copper preparation is added into lubricating oil, so that the extreme-pressure wear resistance of the lubricating oil can be further improved, a noise reduction effect is achieved, and the light-colored transparent requirements of the lubricating oil in appearance can be met.

Description

technical field [0001] The invention relates to a copper powder preparation and its preparation method and application. Background technique [0002] Due to the unique physical and chemical properties that many traditional materials do not have, nanopowders have been widely valued and become one of the hot research topics at home and abroad. The application of nanomaterials in lubricating oil is a very promising multidisciplinary research field. According to the literature [Trenie Iznos, 20 (3), 333-338 (Russian) 1999], it is reported that Russian scientists added nano-copper powder to lubricating oil and found that the lubricating performance was significantly improved, the mechanical wear was reduced by 3-3.5 times and the friction The load was doubled and the tribological properties of the lubricating oil were good. However, elemental nano-copper is easily oxidized in air. Literature "Chemistry Bulletin" No. 10, 1996, pages 55-58, Liu Zhijie, Zhao Bin and others report...
