Polystyrene composite high-toughness storage battery shell body

Abstract

The invention discloses a polystyrene composite high-toughness storage battery shell body and relates to the technical field of storage battery shell bodies. The polystyrene composite high-toughness storage battery shell body is prepared from the following components: polyadipic acid ethylene glycol, N,N-diethyl aniline, sepiolite powder, potassium zirconium carbonate, dioctyl sebacate, polyvinylchloride, polystyrene, sodium hypophosphite hydrate, an anti-impact modifier ACM, paraformaldehyde, chlorinated spirocyclic phosphate, aluminum chloride hexahydrate, triethylamine, tripropylene glycolmonomethyl ether, ammonium octamolybdate and carbon nanotubes. The polystyrene composite high-toughness storage battery shell body disclosed by the invention has the advantages of high efficiency andimpact resistance, high heat resistance, high toughness, fatigue resistance, weather resistance, resistance to corrosion caused by alkali and acid, oil and halogenated hydrocarbon, and strong hydrolysis resistance; a preparation technology is environmentally friendly and utilized equipment is simple, convenient to operate and low in preparation cost, so that the polystyrene composite high-toughness storage battery shell body has very high practical value.

Description

technical field [0001] The invention relates to the technical field of battery casings, in particular to a polystyrene composite high-toughness battery casing. Background technique [0002] The battery is mainly composed of positive plate group, negative plate group, separator, shell and electrolyte. [0003] Among them, the shell is used to hold the electrolyte and support the plate, and there are usually four kinds of glass shells, lead-lined wooden shells, hard rubber shells and plastic shells. The casing is used to contain the electrolyte and the plate group, and should be acid-resistant, heat-resistant, and shock-resistant. The shell is mostly made of hard rubber or polypropylene plastic, which is an integral structure, and there are raised ribs at the bottom to place the plate group. The inside of the shell is divided into 3 or 6 cells that are not connected to each other by the partition wall, and the cells are connected in series with lead mass connection strips. ...

Problems solved by technology

[0004] There are a large number of batteries in daily life to promote a large demand for battery cases, but sometimes there will be collisions, falls, and drops during the production, handling, and use of the case; this will cause the battery case to rupture to a certain extent , if the battery case cover is in the injection molding process, the temperature of a certain process is not well controlled or the internal stress of the plastic case is not completely eliminated, which will also increase the possibility of weak cracks in the case, often after a period of use Micro-cracks appear, causing micro-leakage of electrolyte

If the glue is used improperly when the glue joint of the battery pole is sealed, or due to external force shock or temperature shock, the seal glue joint of the battery will also fail.
