After 30 minutes), the resin was peeled off and the resulting rubber inner tube layer had a thickness of 1.6 mm and the intermediate braided reinforcing layer had a thickness of 0.6 mm.
, the thickness of the rubber outer tube layer is 1.2 mm, and the inner diameter is 9.5 mm.
A wire braid reinforced rubber hose with an outer diameter of 16.3 mm was obtained. The obtained rubber hose was treated by immersing it in six types of ethyl acetate solutions each having a TCICA concentration of 0.1, 0.5, 1, 3, and 5.7% by weight for 6 seconds.
I got a kind of rubber hose. Next, using an etching stamp on each of these six types of rubber hoses, urethane-based ink (manufactured by Seiko Advance, 5G410-210

A coated rubber hose with good adhesion between the coating film and the vulcanized rubber can be obtained. In particular, when printing is applied to the surface of a rubber hose as a coating, the printing will not disappear due to contact with the rubber hose during transportation, storage, or use. In addition, since the printing remains clear, there is no misreading of the display during use, and it is convenient when replacing rubber hoses.
