Abstract

The invention discloses a storage battery case material and a preparation method thereof. The storage battery case material comprises an acrylonitrile-butadiene-styrene terpolymer, polyester resin, diisocyanate, an ethylene-vinyl acetate copolymer, polycarbonate diol, resorcinol bis-polycondensate, melamine cyanurate, chlorinated polyethylene, ethylene bis-stearamide, liquid paraffin, pentaerythritol tetraester, n-octadecyl propionate, diatomaceous earth, graphene oxide, ultrafine calcium carbonate, nanometer titanium dioxide, N-phenylmaleimide, ethyl orthosilicate, potassium persulfate, 2,4-dihydroxybenzophenone, benzoyl peroxide, nanometer silicon carbide, ramie fibers and 1,3-butanediol. Main materials and modifiers for preparing the case material are mixed, and the obtained mixture isheated, plasticized, extruded and formed to prepare the case material. The battery case material has excellent strength and excellent ultraviolet resistance.

Description

【Technical field】 [0001] The invention belongs to the technical field of battery shell material preparation, and in particular relates to a battery shell material and a preparation method thereof. 【Background technique】 [0002] After more than 150 years of development, lead-acid batteries have mature technology, low cost, and excellent performance. They are widely used in many economic fields such as transportation, communication, electric power, military, navigation, and aviation, and have become an indispensable and important chemical power source. As one of the three major parts of lead-acid batteries, the battery case is used to carry all the constituent materials such as plates, separators, and electrolytes. It is required to have good strength, UV resistance, acid and alkali resistance, high strength and good processability.
