Problems solved by technology

But these partitions are not perfect, there are various shortcomings
The rubber separator has high resistance, is brittle and easy to break, and has high cost, and the material used is natural, which has great limitations; the PVC separator has small porosity and high resistance, which has a great influence on the low-temperature starting performance; PP separator The pore size of the plate is large, and the high temperature resistance is poor, which is easy to cause short circuit of the battery; the oxidation resistance and high temperature resistance of the PE separator are poor; the strength of the glass fiber separator is poor, and the pore size is large, which is easy to cause damage and penetration short circuit

Embodiment 1

[0031] Example 1: Weigh raw materials: 20 kg of glass fiber with a diameter of 0.8-15 μm, 80 kg of diatomite with an average particle size of 5-30 μm, 20 kg of polyester fiber with a diameter of 5-15 μm, 0.2 kg of retaining agent, and 10 kg of wet-formed latex and 1 kg of PPE; put the above raw materials into the pulper, add water to adjust the slurry concentration to 1.5%, disintegrate into a slurry with evenly dispersed fibers, and pump it into the pulp storage tank; pass the crushed slurry through Slag remover, papermaking pulp tank and pulp pump are transported to the paper machine production line, among which, the function of the slag remover is to remove glass slag and heavy impurities in the slurry; dilute the slurry to a concentration of 0.03%, and transport it to the paper machine Production line; the slurry is formed, dried and coiled in the paper machine production line, and then copied into a separator base paper; the base paper is added to the coating latex after i...

Embodiment 2

[0032] Embodiment 2: Weigh raw materials: 40 kg of glass fiber with a diameter of 0.8-15 μm, 60 kg of diatomite with an average particle diameter of 5-30 μm, 10 kg of polyester fiber with a diameter of 5-15 μm, 2 kg of retaining agent, 6 kg of wet-formed latex kg and 0.6 kg of PPE; put the above raw materials into the pulper, add water to adjust the slurry concentration to 1.0%, disintegrate into a slurry with evenly dispersed fibers, and pump it into the pulp storage tank; It is transported to the paper machine production line through the slag remover, papermaking pulp tank and pulp pump. The function of the slag remover is to remove the glass slag and heavy impurities in the slurry; dilute the slurry to a concentration of 0.015%, and transport it to the paper machine machine production line; the slurry is formed, dried and coiled in the paper machine production line, and then copied into a separator base paper; the base paper is dipped into the coating latex in the separator ...

Embodiment 3

[0033] Example 3: Weigh raw materials: 60 kg of glass fibers with a diameter of 0.8 to 15 μm, 40 kg of diatomite with an average particle diameter of 5 to 30 μm, 5 kg of polyester fibers with a diameter of 5 to 15 μm, 1.0 kg of retaining agent, and 3 kg of wet-molded latex and PPE 0.1 kg; put the above-mentioned raw materials into the pulper, add water to adjust the slurry concentration to 0.2%, disintegrate into a slurry with uniform dispersion of fibers, and pump it into the slurry storage tank; pass the crushed slurry through Slag cleaner, papermaking pulp tank and pulping pump are sent to the paper machine production line, among which, the function of the slag remover is to remove glass slag and heavy impurities in the slurry; dilute the slurry to a concentration of 0.01%, and send it to the paper machine Production line; the slurry is formed, dried and coiled in the paper machine production line, and then copied into a separator base paper; the base paper is added to the c...

Abstract

The invention relates to a lead-acid battery DE partition and the preparation method, belongs to the accumulator cell technology area, used for sovling the existing flaw of the existing each partition. Its technical plan is that, it is composed by the following weight unit's matter: the glass fiber 20-60, the diatomaceous earth 40-80, the polyester fiber 5-20, wet forming rubber latex 3-10, PPE 0.1-1, maintenance agents 0.2-2; the above raw material after ingredient, pulp purification and transportation, base working, partition processing and so on working procedure produce the product. This invention partition has the merit of litter resistance, thermostable, the corrosion resistance, overcame the flaw of rubber partition easy to break, the rare raw material, also overcome the flaw of PE, the rubber partition poor performance of anticorrosive and heat resistance and the poor absorptivity.

Description

technical field [0001] The invention relates to a battery material and a preparation method, in particular a separator for a lead-acid battery and a power vehicle battery and a preparation method, and belongs to the technical field of batteries. Background technique [0002] The separator is an important component of the battery. It is placed between the positive and negative plates of the battery. The quality of the separator directly affects the discharge capacity and cycle life of the battery. The separator has the following functions in the battery, one is to prevent the positive and negative plates from contacting each other and cause the internal short circuit of the battery; the other is to have a certain strength to prevent the plate from being deformed, bent and the active material from falling off; the third is that the internal storage of the separator is necessary A large amount of electrolyte is required to ensure high conductivity and battery response; the sepa...
