Special plate lug insulation adhesive tape for nickel-metal hydride battery, as well as production method of special plate lug insulation adhesive tape

Abstract

The invention relates to a special plate lug insulation adhesive tape for a nickel-metal hydride battery, as well as a production method of the special plate lug insulation adhesive tape. The adhesive tape comprises a rubber gluing layer, a protective layer, an ink layer, a bottom coating layer, a basic layer and a release layer which are distributed sequentially, wherein the basic layer adopts a biaxially oriented polypropylene film; the bottom coating layer is arranged on the front of the basic layer; the ink layer is arranged on the outer surface of the bottom coating layer; the protective layer is arranged on the outer surface of the ink layer; the release layer is a one-component non-silicone release agent coating layer and is arranged on the back of the basic layer; and the rubber gluing layer is arranged on the outer surface of the protective layer. According to the safe and environment-friendly special plate lug insulation adhesive tape for the nickel-metal hydride battery, the biaxially oriented polypropylene film with powerful puncture strength is adopted, then a gluing surface and a non-gluing surface of the film are preprocessed, the film is coated with a rubber pressure-sensitive adhesive having high viscousness and strong alkali resistance, and the adhesive tape is formed; and the adhesive tape has six layers of structures, and each layer of structures has a respective function.

Description

technical field [0001] The invention relates to an insulating and protective adhesive tape, in particular to a strong alkali-resistant nickel-hydrogen battery special tab insulating tape which is mainly used at the positive tab of a nickel-hydrogen battery and plays the role of insulation protection, and a production method thereof. Background technique [0002] At present, there is no special enterprise in the world that produces special-purpose tab insulation adhesive tape for Ni-MH batteries. The tapes used by general Ni-MH battery manufacturers are not specially developed and designed for the insulation protection of Ni-MH battery tabs, but Ordinary packaging and sealing tape produced abroad (Japan, the United States and other countries). At present, the products that domestic manufacturers can provide are produced by a few small companies imitating foreign packaging tapes. The quality and performance indicators are far from meeting the requirements. The raw materials ar...

Problems solved by technology

At present, the products that domestic manufacturers can provide are produced by a few small companies imitating foreign packaging tapes. The quality and performance indicators are far from meeting the requirements. The raw materials are generally not environmentally friendly, with poor viscosity, reduced peeling force, and low temperature resistance. , Easy degumming of the adhesive, the base material does not meet the expected characteristics, etc., the performance is difficult to meet the use requirements, and it does not meet the environmental protection and safety, and it is even more difficult to adjust the product variety and performance to meet the needs of the market.
