The invention discloses a wear-resistant shell of a storage battery, and relates to the technical field of the processing and production of batteries. The wear-resistant shell is characterized by being prepared from the following materials in parts by weight: 40 to 50 parts of polypropylene, 10 to 15 parts of modified nano calcium carbonate, 4 to 12 parts of mica powder, 1 to 6 parts of poly-4-methyl-1-pentene, 2 to 7 parts of dimethyl phosphate, 9 to 14 parts of polyisobutene, 1 to 4 parts of sodium alkyl benzene sulfonate, 2 to 7 parts of azobisformamide, 2 to 9 parts of calcium lignosulphonate, 9 to 16 parts of adjuvant, 12 to 20 parts of anti-aging agent and 35 to 42 parts of water. A method provided by the invention is reasonable and is convenient to operate, and the wear-resistant shell is high in hardness and is wear-resistant.
