Phosphorylation modified compound high-toughness storage battery shell body

Abstract

The invention discloses a phosphorylation modified compound high-toughness storage battery shell body. The phosphorylation modified compound high-toughness storage battery shell body is prepared fromthe following components: polyphenyl ether, wollastonite powder, tricresyl phosphate, polyvinyl chloride, polystyrene, sodium hypophosphite monohydrate, paraformaldehyde, 35 to 37 percent hydrochloricacid, dichloropentate, aluminum chloride hexahydrate, an oxidation inhibitor, triethylamine, sodium butyl naphthalene sulfonate, aluminum dihydrogen phosphate, butyltin mercaptide, N,N-diisopropylethanolamine, polyimide, phytosterol and an inhibitor. The prepared storage battery shell body has high heat resistance, toughness, weather resistance, high temperature resistance, acid and alkali resistance, and oil and halogenated hydrocarbon corrosion resistance; a preparation technology is environmentally friendly, utilized equipment is simple, convenient to operate, and preparation cost is low;the prepared storage battery shell body is applied to storage battery electrolyte equipment, and has very high practical value.

Description

Technical field: [0001] The invention relates to the field of battery casings, in particular to a phosphorylated modified 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 strip...

AI Technical Summary

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.
