Problems solved by technology

[0005] When the lead-acid battery is in use for a long time, the exterior is easy to be cracked, damaged, and easy to enter water, which makes the battery unable to continue to be used well, which is a kind of damage to the battery itself, and it is easy to cause various problems such as short circuit, which is very serious. Danger, the shell is very important, and the cover on the shell is also very important, but the quality of many shells and covers is not particularly good, and the life span is very short

Abstract

The invention provides a waterproof cover on a shell of a lead storage battery and relates to the technical field of battery processing and production. The waterproof cover 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, 2 to 7 parts of sodium alkylbenzene sulfonate, 1 to 4 parts of hydroxyethyl methacrylate, 9 to 14 parts of o-toluenyl glycidyl ether, 1 to 4 parts of dioctyl phthalate, 2 to 7 parts of diatomite, 2 to 9 parts of chlorinated paraffin, 3 to 10 parts of dibasic lead phosphite, 9 to 16 parts of auxiliary agent, 12 to 20 parts of anti-ageing agent and 35 to 42 parts of water. The waterproof cover provided by the invention has theadvantages of reasonable method, convenience for operation, wear resistance, corrosion resistance and water resistance.

Description

technical field [0001] The invention relates to the technical field of battery processing and production, in particular to a waterproof cover on the shell of a lead storage battery. Background technique [0002] In addition to lithium batteries, commonly used rechargeable batteries, lead-acid batteries are also a very important battery system. The advantage of lead-acid batteries is that the electromotive force is relatively stable during discharge, but the disadvantage is that the specific energy (electric energy stored per unit weight) is small and it is highly corrosive to the environment. Lead-acid batteries have stable working voltage, wide range of operating temperature and operating current, can charge and discharge hundreds of cycles, good storage performance (especially suitable for dry charging storage), and low cost, so they are widely used. [0003] Lead battery (Lead–acid battery): Its volume and weight have not been effectively improved, so it is most commonly...
