Embodiment 1

[0022] Mix 4g of epoxy-functionalized nano-silica (particle size 7-25nm) and 60g of p-aminodiphenylamine, add 15mL of toluene as a solvent, heat up to 140°C, reflux for 6h, and filter at room temperature after the reaction The crude product was collected, rinsed with 20 g of absolute ethanol each time, washed three times, and dried in a blast drying oven at 90°C for 2 hours to obtain the product Nano-AO of the present invention.

[0023]

[0024] See attached Picture 1-1 And attached Figure 1-2 , referring to Table 1, by comparing the infrared spectrogram and thermogravimetric test results of the product of Example 1 and the epoxy-functionalized nano-silica, it can be judged that the product obtained in Example 1 is the target grafted product.

[0027] See attached figure 2 , the product obtained in Example 1 was observed with a scanning ...

Embodiment 2

[0029] The Nano-AO obtained in Example 1 was added to 46# hydraulic oil base oil at 0.1 wt.%, mechanically stirred for 10 minutes and then ultrasonicated for 10 minutes.

[0030] The effects of the additives obtained in Example 1 on the anti-oxidation and anti-wear properties of the base oil were evaluated. The evaluation results of anti-wear ability are shown in Table 2.

[0031] Table 2 Effect of Nano-AO on wear resistance of 46# hydraulic oil base oil

[0032]

[0033] The smaller the diameter of the wear scar, the better the anti-wear ability. It can be seen from Table 2 that the anti-wear ability of the base oil with 0.1wt.% additive is improved.

[0034] The oxidation resistance of the oil added with the additive obtained in Example 1 was investigated by using the temperature-programmed method of pressure differential scanning calorimetry (PDSC). The higher the initial oxidation temperature, the better the oxidation resistance. The temperature-programmed method uses...

Embodiment 3

[0036] The Nano-AO obtained in Example 1 was added to 150SN base oil (Type I) at 0.1 wt.%, mechanically stirred for 10 minutes and then ultrasonicated for 10 minutes.

Abstract

The invention provides an amine nano additive for lubricating oil and an application of the additive, and relates to the technical field of lubricating materials. The additive is obtained by performing a graft reaction on nano-silicon dioxide containing epoxy groups on the surface and p-aminodiphenylamine, can be applied to hydraulic base oil and significantly improve the anti-oxidation function of the oil, and has good dispersion stability and wear resistance in the lubricating oil.

Description

technical field [0001] The invention relates to the technical field of lubricating materials, in particular to an amine nano lubricating oil additive and its application. Background technique [0002] The application and research of nano-lubricating additives began to develop with the birth of nano-technology. Due to the characteristics of small size effect and surface effect of nanoparticles, the new lubricating material prepared based on nano ions combines the advantages of fluid lubrication and solid lubrication, and uses a method different from traditional additives to reduce friction and antiwear. Nanoparticles as solid additives can not only be used in dry friction occasions without oil lubrication, but also can be widely used in oil lubrication situations to form mixed lubrication of fluid + solid. The most researched nano-oil additives (CN108587729A, CN108517239A, CN104531272A) are some layered or scaly solid lubricants with good anti-wear and friction-reducing prop...
