Embodiment Construction

[0018] 1. Wire drawing process section: first set the running speed of the wire drawing furnace at 2 to 3 m / s, and the rotational speed of the drum at 24 to 30 m / s; meanwhile, mix the polyacrylate solution with a solid content of 50% and water at 1 : The ratio of 1.2 is made into solution 40kg;

[0019] Fiberglass consists of 5 # The medium-alkali glass balls are melted and drawn to form glass fibers, and the diameter of the fibers is between 10-15mm; the final fiber weight is about 55-60kg.

[0020] While forming fibers, the polyacrylate solution is evenly sprayed on the glass fibers. After the amount of fibers is reached, a concentrated felt is formed. At this time, the concentrated felt is cut along the axial direction of the roller and spread on a platform. superior.

[0021] 2. Drafting process section: stretch the concentrated felt on the platform horizontally along the cutting direction, and the width of the felt after drafting reaches 1.8-2.3 meters wide.

Abstract

The invention relates to a baffle plate felt of a lead storage battery, characterized in that it is made by continuous glass fiber and adhesive through large roller process, where the continuous glass fiber content is 85-90 (mass)% and the adhesive content is 10-15 (mass)%. The steps are as follows: (1) making basic glass balls in a glass fiber state through a fusing-wiredrawing device, and at the same of forming fiber by wiredrawing, uniformly spraying polyacrylate solution on the glass fiber; and after forming a condensed felt, slicing off the condensed felt along the axis of the roller and spreading it on a platform; (2) transversely drawing the condensed felt on the platform in the cutting direction; (3) at the same time of drawing, drying the drawn felt between 180 deg.C and 200 deg.C; (4) after all the felt is dried, rolling the felt and cutting it into parts. The baffle felt can make the baffle posses the characters of flat surface, strong absorbing ability, good acid resistance, uniform thickness, fewer potassium permanganate reducing matter, etc.

Description

technical field [0001] The invention relates to a base material of a lead-acid battery separator, in particular to a novel lead-acid battery separator felt. Background technique [0002] The base material of the traditional lead-acid battery separator is ultrafine microfiber, which has poor mechanical strength. In addition, the separator will cause the active material to fall off due to vibration during use, so the shock resistance is also poor, which affects the lead-acid battery. lifespan. [0003] At present, there is a kind of lead-acid battery composite separator, which is made of fixed-length glass fiber as the base material and PVC or rubber. Its mechanical and shock resistance performance is improved compared with ultra-fine fiber separator. The service life of the plate-assembled lead-acid battery is 15%-20% higher than that of the ultrafine microfiber separator plate-assembled lead-acid battery. Contents of the invention [0004] The technical problem to be sol...
