Abstract
The invention relates to a battery separator felt with low reduzate and ion contents and a preparation method thereof. The battery separator felt is characterized by being prepared from 70-90 percent by mass of segmented installation glass fiber and 10-30 percent by mass of caking agent by fiber forming, gum impregnation, drying and rolling work procedures. The battery separator felt with low reduzate and ion contents has the advantages of uniform thickness, no hole, no stain and the like; the content of the reduzate is low; the contents of chloride ions and ferric ions are low; the acid resistance is favorable and the strength of products is higher; and the products produced with the preparation method of the battery separator felt with low reduzate and ion contents are stable and can stably operate.
Description
Technical field
The present invention relates to a kind of low reduzate, low ion concentration battery separator felt and preparation method thereof, belong to storage battery base material field.
Background technology
Along with the continuous development of society, and the raising of people's living standard, people are also more and more higher for the requirement of material life.Wherein the development of new material is particularly outstanding, and application research and development and market development that glass fiber product is new also should actively operate.Separator felt is mainly used in storage battery and makes the field at present, and demonstrate tangible porous, low resistance, high temperature resistant and oxidation resistant performance, little as viscosity, suspension good, shrinkage is low etc., thereby can effectively prevent coming off of active material that accumulator plate causes owing to automobile bumpiness, can prolong the 15%-20% in useful life of storage battery.
Because there is reducing substances in the glass fibre, and the content of the original is difficult to control, thereby has influence on the performance and the quality of storage battery but in use.
Summary of the invention
According to the deficiency of above technology, the technical problem to be solved in the present invention is: a kind of battery separator felt and preparation method thereof is provided, and its reduzate and ion concentration are low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of low reduzate, low ion concentration battery separator felt, it is characterized in that it is made by fiberizing, impregnation, oven dry, winding process by section glaze fiber and binding agent, wherein the glass fibre mass fraction is 70～90%, and the adhesive mass fraction is 10～30%.
Described binding agent is a modified polyacrylate.
The solid content of described modified polyacrylate is 40～50%.
The preparation method of described low reduzate, low ion concentration battery separator felt is characterized in that comprising the steps:
(1) filament is sheared: according to equipment requirements glass fibre is sheared by size;
(2) adhesive preparation: single according to binder making technology, add pure water, coupling agent, high-speed osmotic agent, polyacrylic resin, defoamer item by item, the coupling agent that is added, tell that bleeding agent, defoamer all are commonly used in the industry, are known technology;
(3) fiberizing: use tackifier in the water, and install flow straightener additional on former top;
(4) impregnation: binding agent utilizes adhesive applicator, is poured into uniformly on the felt face, and control suction negative pressure is-30～-40bar;
(5) oven dry: bake out temperature is controlled at 100～250 ℃, and oven dry back polyacrylate state of cure is hanged down reduzate, low ion concentration battery separator felt surfacing 95～99%, and is not stratified;
(6) rolling: after oven dry finishes, will hang down reduzate, low ion concentration battery separator felt rolling.
Described tackifier are hydroxyethylcellulose, and consumption is 0.1～0.2%.
Described flow straightener bottom is lower than liquid level.
The invention has the beneficial effects as follows: thickness is even; No hole, no spot etc.; The content of reduzate is low; The content of chloride ion, iron ion is low; Acid resistance is good, the product strength height.The product that the preparation method of this low reduzate, low ion concentration battery separator felt produces is stable, operates steadily.
