NOVELTY - A nickel-hydrogen battery pole ear insulating adhesive tape, comprises: rubber adhesive layer (1), protective layer (2), ink layer (3), undercoat layer (4), base layer (5) and release layer (6); where base layer is biaxially oriented polypropylene film, undercoat layer is provided on front face of base layer, ink layer is disposed on outer coating layer of undercoat layer, protective layer is set on outer surface of ink layer, release layer is single-component non-silicon release agent coating and is set on back of base layer, and rubber adhesive layer is set on protective layer surface.    USE - As nickel-hydrogen battery pole ear insulating adhesive tape (claimed).    ADVANTAGE - The nickel-hydrogen battery pole ear insulating adhesive tape is safe and environment-friendly. The biaxial oriented polypropylene film provides puncture strength. The biaxial oriented polypropylene film is then subjected to pre-processing and comprises non-adhesive film coated with adhesive. The strong alkali resistant pressure-sensitive rubber adhesive that is used to form adhesive tape, has multi-layer structure, where each layer is provided with respective function, such that rubber adhesive layer is directly contacted with nickel-hydrogen battery anode electrode ear part, has super strong adhesive effect, adheres firmly to pole ear that avoids short circuit, and prolongs service life of product. The strong alkali resistant ink coating is in accordance with environmental protection requirement i.e. Restriction of Hazardous Substances Directive (RoHS). The strong alkali resistant ink coating is protected by protective layer. The strong alkali resistant ink coating can be prepared according to type suitable for different product requirements. The undercoat layer increases adhesive force of base material layer formed of biaxial oriented polypropylene film. The tape can be applied to soft and hard surfaces of substrate to prevent piercing, has excellent adhesion performance, and quickly dries on substrate layer.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for producing the nickel-hydrogen battery pole ear insulation adhesive tape, involving: firstly carrying out corona treatment on back of biaxially oriented polypropylene film till corona value reaches to greater than or equal to 38 dynes/cm, then forming single-component non-silicon release agent at concentration of 0.5-2%, printing single-component non-silicon release agent on back face of biaxially oriented polypropylene film, processing back side of biaxially oriented polypropylene film, using copolymer coating of ethylene and vinyl acetate for undercoating layer and coating on biaxial oriented polypropylene film front face, printing strong alkali resistant ink coating on undercoating surface, printing on ink layer surface thin layer of transparent varnish as protective layer, then coating pressure-sensitive rubber having good dissolution on outer surface of protective layer, and at last drying, coiling, rewinding, and cutting into tape.
