Abstract
An oil gel capsule includes an oil gel including an oil and a gelator, and at least one surfactant bonded to the oil gel. A contact part for a vehicle includes an overlay layer formed on a surface of the contact part, the overlay layer comprising oil gel capsules, wherein the oil gel capsules including an oil gel including an oil and a gelator, and at least one surfactant bonded to the oil gel.
Claims17
An oil gel capsule comprising:
- an oil gel comprising an engine oil and a gelator;
- and
- a surfactant bonded to the oil gel;
- wherein the gelator is 12-hydroxyoctadecanoic acid;
- wherein a content of the 12-hydroxyoctadecanoic acid is 1 to 10 wt % based on a total weight of the engine oil;
- wherein the oil gel has a phase transition temperature of about 60° C. to about 70° C.;
- and
- wherein the oil gel capsule has a size of about 0.1 μm to 1 μm.
A contact part for a vehicle, the contact part comprising:
- an overlay layer formed on a surface of the contact part, the overlay layer comprising oil gel capsules, wherein the oil gel capsules comprise:
- an oil gel comprising an engine oil and a gelator;
- and
- at least one surfactant bonded to the oil gel;
- wherein the gelator is 12-hydroxyoctadecanoic acid;
- wherein a content of the 12-hydroxyoctadecanoic acid is 1 to 10 wt % based on a total weight of the engine oil;
- wherein the oil gel has a phase transition temperature of about 60° C. to about 70° C.;
- wherein the oil gel capsule has a size of about 0.1 μm to 1 μm;
- and
- wherein the overlay layer has a thickness of 10 μm to 30 μm.
A method for manufacturing a contact part for a vehicle, the method comprising:
- manufacturing oil gels by mixing an oil and a gelator;
- producing a plurality of oil gel capsules by mixing the oil gels and an aqueous surfactant solution to form an aqueous solution;
- recovering oil powder by drying the oil gel capsules and the aqueous solution;
- preparing a first organic solution comprising 2 to 10 wt % of the oil gel capsules by re-dispersing the oil powder in an organic solvent;
- preparing an overlay mixed solution by mixing the first organic solution and a second organic solution comprising 30 to 50 wt % of polyamideimide and an additive at a weight ratio of 1:0.5 to 1:2;
- coating a surface of the contact part with the overlay mixed solution;
- and
- drying the contact part to form an overlay layer from the overlay mixed solution;
- wherein the oil is an engine oil;
- wherein the gelator is 12-hydroxyoctadecanoic acid;
- wherein a content of the 12-hydroxyoctadecanoic acid is 1 to 10 wt % based on a total weight of the engine oil;
- wherein the oil gel has a phase transition temperature of about 60° C. to about 70° C.;
- wherein the oil gel capsule has a size of about 0.1 μm to 1 μm;
- and
- wherein the overlay layer has a thickness of 10 μm to 30 μm.
