The invention discloses rubber for binding of a titanium starting sheet and a method for using the rubber for binding and belongs to the technical field of electrolytic nickel and cathode copper produced through electrolytic cells. The rubber is used for solving the problems of complex binding process, short service life and low quality and grade of the electrolysis products of the binding rubber. The rubber comprises ethylene propylene terpolymer, chlorosulfonated polyethylene rubber, stearic acid, paraffin wax, diethylene glycol, silicon dioxide, carbon black, vaseline, magnesium oxide, dicumyl peroxide, zinc methacrylate and sulfur. A use method comprises the following steps: confirming pressing size, treating metal surface, pressing and molding and performing after-treatment. The rubber and the special adhesive disclosed by the invention have excellent corrosion resistance and anti-ageing property, are nonconductive, are capable of resisting against high temperature and alternate cooling and heating, are free from the conditions of brittleness and adhesive strength reduction and are high in bonding strength with the titanium starting sheet; the rubber, the special adhesive and the titanium starting sheet can be seamlessly spliced with each other; the edge or tip effect can be avoided; the rubber is combined with the four edges of the titanium starting sheet; the cutting process is avoided; the grade of the titanium starting sheet is increased; the service life is prolonged; and the labor intensity is reduced.
