Problems solved by technology

However, the high viscosity of the lubricant composition and the restricted size of the pores in the bearing limit its application
In addition, there are limitations in mentioning lubricant compositions as a method of prolonging the life of composites as there is no disclosure of lubricant compositions as covering materials for bearings

Embodiment 1

[0072] An NMP solution (first organic solution) including 10 wt% of oil gel capsules was prepared by adding 10 g of oil powder to 90 g of NMP solvent. After preparing the first organic solution, the oil gel capsules were uniformly redispersed in the NMP solvent using a blender. After preparing an NMP solution (second organic solution) including 50 wt% of polyamideimide and additives (including lubricant), by mixing 50 g of the first organic solution and 50 g of the second organic solution, a covering mixed solution was prepared . After the surface of the bearing alloy is coated with the covering mixed solution and dried at 150°C-200°C for 30 minutes, a covering layer with a thickness of about 10 μm is prepared by drying the surface of the bearing alloy at 210°C-240°C for 15 minutes (Example 1 by Figure 16 and 17 Indicated by sample 1 in ).

Embodiment 2

[0074] A coating having a thickness of about 20 μm was prepared by coating the surface of the bearing alloy twice with the covering mixed solution in Example 1 (Example 2 by Figure 16 and 17 Indicated by sample 2 in ).

Embodiment 3

[0076] A coating with a thickness of about 30 μm was prepared by coating the surface of the bearing alloy three times with the covering mixed solution in Example 1 (Example 3 by Figure 16 and 17 Indicated by sample 3 in).

Abstract

The present invention relates to a method for manufacturing oil gel capsules and a method for manufacturing a contact part for a vehicle, including the oil gel capsules. The present disclosure relates to manufacturing the oil gel capsules and adding the oil gel capsules to an overlay layer of the contact part for the vehicle. The present disclosure may provide a method for manufacturing the oil gel capsules and the method for manufacturing the contact part for the vehicle, including the oil gel capsules. The oil gels in the oil gel capsules manufactured by the present disclosure may respond to the temperature environment of the contact part for the vehicle, and an aggregation phenomenon of gelators or an aggregation phenomenon of surfactants may not occur even after an oil is released. Therefore, as oil gel capsules are added to an overlay layer, the present disclosure may improve low friction characteristics and seizure resistance characteristics of a contact part for a vehicle without any side effects caused by the above-described aggregation phenomenon.

Description

[0001] Cross References to Related Applications [0002] Pursuant to 35 U.S.C §119, this application claims priority to Korean Patent Application No. 10-2019-0168354 filed on December 16, 2019 at the Korean Intellectual Property Office, which is hereby incorporated by reference in its entirety . technical field [0003] The present disclosure relates to a material for a coating formed on the surface of a vehicle contacting component such as a bearing alloy. Background technique [0004] A bearing is one of the mechanical elements that constrains relative motion to a desired motion and reduces friction between moving parts. Since bearings are equipped with hard chains or balls and are thus prone to fatigue fracture, alloy-based bearings (hereinafter referred to as bearing alloys) that are excellent in wear resistance, corrosion resistance, and thermal conductivity and have a vibration-absorbing function are generally used. [0005] However, bearing alloys also inevitably su...
