Abstract

The invention relates to the technical field of capacitors, in particular to an explosion-proof rubber sealant cover for supercapacitors. The explosion-proof rubber sealant cover is characterized by comprising the following raw materials by weight part: 32-38 of high benzene rubber, 22-32 of polyacrylic rubber, 6-12 of titanium dioxide, 3-5 of zinc stearate, 3-5 of lecithin, 5-10 of graphene oxide, 5-10 of aluminum oxide, 3-5 of tea polyphenols, 5-10 of zinc dimethyldithiocarbamate, 3-5 of talcum powder, 2-4 of sulfur and 3-5 of montmorillonite. The preparation method of the explosion-proof rubber sealant cover provided by the invention is simple, and compared with the prior art, has the advantages of reduced energy consumption, green and environmental protection. The prepared product has a reasonable formula, good mechanical properties, fatigue performance, aging resistance, lower heat generation, and good comprehensive performance, and can effectively prevent burst of capacitors by installing on the shells of the supercapacitors.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to an explosion-proof rubber sealant cover for super capacitors. Background technique [0002] As a new environment-friendly energy storage system between traditional capacitors and lithium-ion batteries, supercapacitors have many excellent characteristics unmatched by other energy storage devices, and their capacity can reach hundreds or even thousands of farads. provide green solutions to problems such as depletion and environmental degradation. [0003] Since supercapacitors are generally composed of electrode materials, electrolytes, current collectors, and diaphragms, etc., if the capacitor fails, it will burst, and the electrolyte will leak out to pollute the machine and equipment, and there is a danger of fire. It has always been an important field of scientific research to find a kind of explosion-proof rubber and its products with better mechanical properties, fatigue p...
