Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the deficiency that the conventional acrylic fiber is too soft, and the dispersibility is poor after being cut into ultra-short fibers, and cannot be used as an additive material for battery pole plates, and a kind of acrylonitrile fiber used for battery pole plates is provided. and its production method, the fiber is infiltrated with polydimethylsiloxane, thereby improving the wrinkle resistance of the fiber, making the fiber stronger, easy to cut into ultra-short fibers, and has good dispersibility, becoming Excellent Additive Materials for Making Battery Plates

Abstract

The invention discloses an AN-VDC (acrylonitrile-vinylidene chloride) copolymer fiber used for battery plates and a production method thereof. Polydimethyl siloxane is doped in the AN-VDC copolymer fiber; and in the production method, only one pass of oiling process is performed on fiber bundles after drafting, the fiber bundles are treated by polydimethyl siloxane emulsion and dried, and then the fiber bundles directly enter a cutting process. The invention also discloses a novel battery plate in which short cut fiber formed by cutting the AN-VDC copolymer fiber is added. According to the production method of the AN-VDC copolymer fiber disclosed by the invention, the traditional process flow is improved, and polydimethyl siloxane is doped into the produced AN-VDC copolymer fiber, so thatthe crease resistance, dispersibility and anti-sag property are improved, and the AN-VDC copolymer fiber can be cut into short cut fibers easily. Because the short cut fibers formed by cutting the AN-VDC copolymer fiber are used as an addition material to the battery plate disclosed by the invention, the battery plate has the advantages of high strength, shock resistance and long service life, and can be applied to various lead-acid batteries.

Description

Technical field: [0001] The invention relates to an acrylic fiber, in particular to an acrylic fiber used as an additive material for battery pole plates and a production method thereof. Background technique: [0002] The most widely used plate in domestic and foreign batteries is the paste plate, which is made of lead powder, sulfuric acid, water, additives and other materials mixed and stirred into a paste, and coated on the grid made of alloy. of. Since the bonding force between the lead paste itself is small and easy to fall off, ultra-short fibers are generally added to the lead paste to strengthen the bond, so as to increase the strength of the plate, prevent the active material on the plate from falling off, and prolong the life of the battery. service life. At present, the fibers added to battery plates at home and abroad are mainly polyester fibers and polypropylene fibers. However, due to the constraints of their own performance, these fibers have the disadvantag...
