Problems solved by technology
However, ordinary non-woven fabrics also have certain problems. For example, because the pores on the surface are blocked, lead paste (lead paste) as an active material is not easy to adhere, and the outer cover with a large denier and a small number of fiber structures causes the lead paste to ooze out. A certain amount of pressure is applied in each process, and there is a problem of not separating each other after the ripening process, but no solution has been proposed for this problem so far

Embodiment Construction
[0020] Hereinafter, the present invention will be described in detail according to preferred embodiments with reference to the accompanying drawings.
[0021] figure 1 As a schematic diagram of an ordinary lead-acid battery, it is an enlarged diagram showing the plate and its constituent materials; figure 2 It is a cross-sectional view of a multilayered spunbonded nonwoven fabric for a battery separation membrane active material holder of the present invention.
[0022] Such as figure 2 As shown, the spunbonded nonwoven fabric for the battery separation membrane active material support of the present invention is composed of a first fiber layer 31 and a second fiber layer 32 .
[0023] image 3 It is a flowchart showing the manufacturing process of the vehicle battery pole plate. As a general battery pole plate, the lead plate is processed in a mesh form, and lead oxide and lead powder are mixed with water, sulfuric acid and other additives to make a lead paste (paste) )...

The invention relates to a spunbond non-woven fabric for supporting and an active material of a battery and a manufacturing method thereof. The non-woven fabric is composed of multiple layers of fiber structures having different sizes. A nozzle used in the first fiber layer is within 200 micro meters and provided with 200 to 300 spinnerets having a diameter of 0.4 micro meters. The nozzle is used for manufacturing long fibers having 1 to 3 deniers. A nozzle used in the second fiber layer has the same size and diameter with the first fiber layer and the number of spinnerets is 30 to 180. The size of the polyester long fiber is 5-15 deniers. And the polyester long fiber is manufactured by laminating multiple layers of nets and through a method of heat healing and pricking. The adhesive force of the active substance on the second fiber layer composed of the large size fiber is improved. The first fiber layer composed of small size fiber prevents the leakage of the adhered active material, thereby retaining the adherence. The leakage of the active material and the mutual adherence are prevented, thereby improving the separating performance.
Description
technical field [0001] The present invention relates to a kind of spun-bonded non-woven fabric for battery active material support and its manufacturing method, more specifically relates to a kind of surface that is attached to the lead and lead oxide of the vehicle-mounted battery, improves the simplicity of the manufacturing process and is installed inside the battery A spun-bonded nonwoven fabric for a battery active material holder with a multilayer structure capable of preventing the outflow of active material lead paste generated by the reaction with dilute sulfuric acid, and greatly increasing battery life with excellent durability, and a manufacturing method thereof. Background technique [0002] Generally, various batteries (batteries) widely used in automobiles, ships, agricultural machinery or other industries are arranged in a large amount of dilute sulfuric acid and lead and lead oxide plates in the form of plates, which are formed by the interaction of dilute su...
