This invention discloses a waterproof and anti-sticking ink for sterilization monitoring indicator tapes, comprising a mesoporous nanomaterial, an oil-based binder, an oil-based diluent and a defoamer. During the production of the sterilization indicator tape, the color-changing ink is printed on medical-grade textured paper tape substrate and then waterproof and anti-sticking ink is coated thereon. The mesoporous nanomaterial in the waterproof and anti-sticking ink can provide the penetration of vapor and impermeability of condensed water. The oil-based binder can withstand high temperature vapor, and has excellent adhesion to a textured paper substrate, with the adhesion level being ISO-4B; and the oil-based binder can link the mesoporous material together to form a layer of dense mesh structure on the indicator tape, thereby enhancing the adhesion of the waterproof and anti-sticking ink on the tape surface and preventing the waterproof coating from being stuck away by a pressure-sensitive adhesive during the winding process.
