Abstract

A Vinyon N cell fiber mixed with polythene dimethyl silicon, and its production and accumulator polar plate are disclosed. The process is carried out by stretching for fiber tow, applying oil, treating by polythene dimethyl silicon oil solvent, drying and cutting. Ultra-short fibers of Vinyon N cell fiber are added into accumulator polar plate. It has better strength and long usage life, and has excellent non-crease, anti-impact and ultra-short cutting performances, excellent dispersion and hardness. It can be used for various plumbous acid accumulators.

Description

Technical field: [0001] The invention relates to an acrylonitrile fiber, in particular to an acrylonitrile battery fiber which can be used as an additive material in battery pole plates and its production method and application. Background technique: [0002] The most widely used electrode plate in lead-acid batteries is the paste-type plate, which is made of lead powder, sulfuric acid, water, additives and other materials mixed and stirred into a paste, and coated on the grid made of alloy. made. Because the bonding force between the lead paste itself is small and easy to fall off, ultra-short fibers are usually added to the lead paste to strengthen the bond, thereby increasing the strength of the plate, preventing the active material on the plate from falling off, and prolonging the life of the plate. battery life. At present, the fibers added to battery plates at home and abroad are mainly polyester fibers, polypropylene fibers, etc. Although these fibers have certain a...
