The invention discloses a high filling easy-peel acidproof rubber belt which comprises a substrate, wherein the substrate comprises a PET (polyethylene terephthalate) layer and a CPP (chlorinated polypropylene) film layer; the PET layer is bonded with the CPP film layer through elastic glue; and the surface of a CPP film is coated with acidproof glue. The rubber belt is novel in structural design,has good elasticity, segment gap makeup ability and acid resistance, and is high in toughness, good in compression resistance effect, uneasy to tear and long in service life.
