Abstract

The invention discloses a paper pulp which is used for sized diaphragm paper of an alkaline cell and has the function of separating a positive electrode and a negative electrode in the alkaline cell and a preparation technique for applying the pulp material to prepare the diaphragm paper. The paper pulp consists of pulp materials and auxiliary materials; the pulp materials consist of ultrafine vinylon fiber, ultrafine viscose fiber, water soluble vinylon fiber and cotton pulp; and the auxiliary materials consist of an antifoaming agent and a dispersing agent. The sized diaphragm paper of the alkaline cell prepared by the paper pulp can greatly reduce the defects of lumps, air bubble holes and the like, thus improving the tube-making performance and discharge performance of the diaphragm paper in producing the alkaline cell and stability of the diaphragm paper product; and the technique for applying the paper pulp to produce the diaphragm paper not only has high production efficiency, but also has little environmental pollution.

Description

technical field [0001] The present invention relates to a kind of battery component and processing method, specifically, the present invention relates to a kind of paper slurry of glued alkaline battery diaphragm paper which plays the role of blocking positive and negative electrodes in alkaline battery and the preparation of using the paper slurry Preparation process of separator paper. Background technique [0002] With the continuous development of science and technology and economy, more and more electrical appliances have entered people's life and work. As an important power supply for electrical The advantages of light weight and stable power supply voltage and current are becoming more and more widely used. With the increasing importance of batteries in people's lives, high-performance battery production has been paid more and more attention. [0003] Alkaline batteries are also known as alkaline zinc-manganese batteries and alkaline manganese batteries, and are the...
