Characteristic, has a very strong adsorption capacity, good dispersive property, can improve compound glass microfibre shock resistance, it is antifatigue,
Dimensional stability and gas barrier property.In addition, montmorillonite has fluxing action, and the temperature that the system that can reduce is founded, energy-conservation
Consumption reduction.Tekite sand is the amorphous silica produced by electric smelting method（Electric smelting temperature reaches 1800-2000
℃）, the energy consumption in production process can be directly reduced in system using tekite sand.
Preferably, step（1）In, glass melting temperature is 800 ~ 1000 DEG C.
Preferably, step（2）In, the number of the porous bushing is no less than one.
During high speed wire drawing of the present invention, kiln can be connected up to a hundred porous bushings by a plurality of path and be produced simultaneously.This
Kind process efficient high yield, it is easy to extensive full-automatic production.
Preferably, step（1）In, the weight is：10 ~ 25 parts of pyrophyllite, 20 ~ 30 parts of nano aluminum nitride,
25 ~ 35 parts of 25 ~ 30 parts of montmorillonite, 5 ~ 10 parts of elastomer and tekite sand.
Elastic fiber material is introduced in the formula system of compound glass microfibre, this specialty fibers are a kind of good
Polymer, its shape and structure will not change under the environmental condition of acid and heat, the compound glass strengthened using the elastomer
Puncture-resistant intensity of the AGM dividing plates made from microfibre under dry, hygrometric state is big, and tensile strength is high, and resilience is good.
Preferably, the elastomer is selected from high resiliency PEF fiber, spider silk, in polyurethane fiber and silk
It is one or more of.
High resiliency PEF fiber, referred to as high resiliency or high-modulus polyethylene fibres are molecular weight 100~500
The ten thousand spun fiber of polyethylene institute, for current specific strength and specific modulus highest fiber in the world, belongs to hydrophilic acidproof synthesis
Fiber, resistance to strong acid corrosion.Spider silk is the most tough fiber of nature, its fracture strength 1.3GPa, elongation 40%, is described as
" biological steel ", the present invention, as elastomer, greatly reduce chemical reagent using by biological material spider silk and silk
Use, building-up process is more green.The present invention adds high resiliency PEF in the formula system of compound glass microfibre
Fiber, spider silk, polyurethane fiber or silk, using the tensile strength of AGM dividing plates made from compound glass microfibre of the present invention
Greatly improved with elasticity, the production efficiency of battery can be improved, reduce the percent defective of battery assembling process, improve battery
Performance, increase the service life.
Therefore, the present invention has the advantages that：Technique process is simple, energy-saving, stable molding, efficient high yield,
