DETAILED DESCRIPTION OF THE INVENTION

[0018] Referring to FIGS. 1 to 3, an intermediary pre-applied before sealant in accordance with a first preferred embodiment of the invention is formed a coating layer 12 after applying. The coating layer 12 comprises a first surface 22 and a second surface 24 being corresponding to the first surface 22.

[0019] In practice, an emulsion formed by the intermediary disclosed in the invention is applied to an inner surface 42 of a tire 14 such as a tire with tubeless technology. The first surface 22 has a first adhesive force 221 for attaching to the inner surface 42 of the tire 14. Preferably the coating layer 12 possesses a thin and uniform layer possessing smoothness.

[0020] At least 1˜2 hours after the coating layer 12 is formed, a conventional sealant is injected into the tire 14 in an appropriate amount, and then the tire 14 is rolled so that a part of the sealant 16 is coated on the second surface 24 of the coating layer 12 and a suitable liquid sealant still remains inside the tire 14. The second surface 24 and the attached sealant 16 have a second adhesive force 241.

[0021] When the tire 14 is punctured and there is a hole, the liquid sealant is pressed out of the hole by the high pressure gas inside the tire 14, and then the liquid sealant solidifies in the hole to have the effect of repair the tire 14.

[0022] When the tire 14 has not been punctured for a period of time, all the original sealant 16 is attached to the second surface 24 of the coating layer 12. At this time, the original sealant 16 should be removed, and then a new sealant is needed to injected again and a suitable liquid sealant still remains inside the tire 14 to maintain the effect of repairing the tire 14.

[0023] When the sealant 16 is released and the second adhesive force 241 is greater than the first adhesive force 221, the sealant 16 and the coating layer 12 are released from the inner surface 42 of the tire 14 together. When the sealant 16 is released and the first adhesive force 221 is greater than the second adhesive force 241, the sealant 16 is separated from the coating layer 12.

[0024] With the intermediary disclosed in the invention, we can easily release the sealant 16 without leaving the sealant 16 inside the tire 14.

[0025] The intermediary disclosed in the invention at least comprises a paraffin wax, a lanolin, a vegetable oil and an emulsifier being formed an emulsion. Wherein, preferably, the paraffin wax can have the property of repelling anionic products. The vegetable oil can include a palm oil such as a carnauba oil and/or other vegetable oil such as a sunflower oil, an olive oil, a canola oil, a coconut oil and etc. The emulsifier can be a cleaning agent/detergent. Preferably the emulsifier can be a solvent-free cleaning agent/detergent.

[0026] When the intermediary disclosed in the invention is made into an emulsion, an appropriate amount of water, such as distilled water, can be added to achieve the effects of emulsifying and adjusting the consistency. Preferably its weight percent component is 20˜40% paraffin wax, 5˜15% lanolin, 2˜8% palm oil, 30˜50% other vegetable oil, 2˜8% detergent and 5˜15% water. Its pH value is 7˜9.

[0027] The intermediary disclosed in the invention allows the liquid sealant to slide easily without hindering the efficacy of the sealant, also aids in tire hydration, and let the rubber be soft and longer. The intermediary can be sponged onto the inside of the tire to create friction with the tire to create a thin and even layer that helps to adhere to the tire and allows the sealant to work best. The intermediary disclosed in the invention can work at temperatures between −10° C. and 30° C., but the intermediary can also work at 50° C. without any physical change.
