Abstract
The invention relates to a preparation method of a dacron non-woven racking pipe for a lead-acid storage battery, belonging to the technical field of a high molecular material. The preparation method comprises the following steps of: sewing two layers of dacron fiber substrates with the same specification at equal intervals along a length direction, so as to obtain a dacron basic fabric of the non-woven racking pipe; immersing the sewed dacron basic fabric into cured glue liquid and completely immersing; wiping redundant mucilage and drying; after drying the dacron basic fabric, pulling on a core mould; curing and sizing at a high temperature; and after the curing, taking out the core mould to obtain the finished racking pipe. With the adoption of the preparation method disclosed by the invention, the production process is simplified and the production cost is reduced; the prepared racking pipe has the properties of higher porosity and acid absorption amount, so that the resistance is very small and the capacity of the battery is easy to improve; the specially-prepared non-woven substrate is provided with a pore structure which is more tiny and roundabout so that grains of active substances can be kept for a longer time and the service life of the battery is obviously prolonged; and the prepared racking pipe has a good anti-deformation capability.
Description
Technical field
The preparation method who the present invention relates to a kind of dacron non-woven racking pipe for lead-acid storage battery, belongs to technical field of polymer materials.
Background technology
In tube type lead-acid accumulator, comb, as the important composition parts of battery, even plays conclusive effect in some cases to the performance of battery, and the raising of each comb quality, is all accompanied by significantly improving of performances of the lead-acid battery.
Comb holds material as tubular type battery positive electrode active material, has experienced single tube by various materials to the up-to-date non-woven gauntlets of weaving formula comb.Compared with terylene calandria, non-woven gauntlets has less aperture, higher porosity and the better advantage such as electrolyte retention, lower resistance, battery performance is increased significantly, it is the perfect match material of tubular type lead-acid battery, colloid battery, flooded batteries, representing the last word of tube type lead-acid accumulator technology, but existing non-woven gauntlets manufacture craft exists complex process, high in cost of production shortcoming.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: a kind of above-mentioned defect that solved is provided, simplify production technology, reduced production cost, improved the storage battery preparation method of dacron non-woven racking pipe of the combination property of comb.
The technical solution adopted for the present invention to solve the technical problems is: the preparation method of described dacron non-woven racking pipe for lead-acid storage battery, is characterized in that comprising the following steps:
A, the polyster fibre base material of two-layer same size is equidistantly united by a seam along length direction, stitch pitch is 12mm～14mm, obtains non-woven gauntlets terylene base cloth;
B, the terylene base cloth sewed up is immersed and solidified in glue, after soaking into, unnecessary rubber cement is extracted, and dried, bake out temperature is 75 DEG C～85 DEG C;
After c, terylene base cloth drying, put on core, solidifying and setting under 160 DEG C～180 DEG C high temperature, be 4～6 minutes curing time, after having solidified, takes out core, comb gets product.
Curing glue in described b step consist of acrylate, activating agent, deionized water, the mass ratio of each component is acrylate: activating agent: deionized water=100: 5: 0～100.
The acrylate of selecting is the acrylate emulsion type adhesive weaving emulsion of Dongling District, Shenyang City east peaking plant produced.
Described activating agent consist of LAS (sodium n-alkylbenzenesulfonate), AES (sodium sulfate of polyethenoxy ether of fatty alcohol), AEO-9 (AEO), the mass ratio of each component is LAS: AES: AEO-9=3: 1: 1.
The diameter of the core in described c step is 8.4mm.
D.C. resistance≤0.0035 Ω dm2/ the sheet of the comb making, volume porosity >=65%.
The beneficial effect that the present invention has is:
The present invention has simplified production technology, and has reduced production cost; The comb making has higher porosity and inhales sour flow characteristic, makes resistance very little, contributes to improve the capacity of battery; Adopt the non-woven substrate of special preparation, there is trickleer and roundabout pore structure, active material particle can be retained more muchly, significant prolongation battery life; There is good non-deformability, be enough to resist active force suffered in active material stowing operation and in battery charging and discharging cyclic process; Be applicable to squeeze cream formula (wet type), be applicable to again powder filling formula (dry type) manufacturing process, non-woven gauntlets can ensure wet type active material uniformity and be deposited in pipe, and under powder filling formula (dry type) process conditions, non-woven gauntlets can keep the lead powder that particle diameter is thinner better.
