Abstract

The invention discloses an electronic detonator detonated solid polymer capacitor and a manufacturing method of the solid polymer capacitor. The manufacturing method comprises the following steps of (1) winding a core package; (2) carrying out formation repair treatment; (3) impregnating; (4) heating and polymerizing; (5) impregnating an additive, namely immersing the core package subjected to heating polymerization treatment into the additive for additive impregnation treatment, taking out the core package and then drying the core package, wherein the additive is prepared from the following components in percentage by weight of 30%-35% of butyrolactone, 20%-25% of sulfolane, 20%-25% of triethylamine phthalate and 15%-20% of PEG400 (Polyethylene Glycol 400); (6) packaging, namely filling the core package obtained in the step (5) into a shell and sealing the shell with a rubber plug; (7) pouring glue and curing; (8) aging. According to the solid polymer capacitor manufactured by the manufacturing method, the technical problem that a leakage current rises and even exceeds the standard range due to the fact that a conductive polymer layer in a product is damaged when the existing electronic detonator detonated solid polymer capacitor is in an external force operation or vibration environment, is solved.

Description

technical field [0001] The invention relates to the technical field of capacitor manufacturing, in particular to an electronic detonator detonating solid polymer capacitor and a manufacturing method thereof. Background technique [0002] Electronic detonators were first designed to use tantalum capacitors, but the price of tantalum capacitors is high, and the long delivery time cannot meet the requirements; and the low-cost liquid capacitors cannot meet the requirements due to their low temperature characteristics, so solid capacitors are developed and used. At present, the national demand for electronic detonators is 2.6 billion rounds per year, and 480 million solid capacitor electronic detonators will be used in 2019. Subsequent gradually switch to 100% use of solid capacitors. If all solid capacitors are used in the field of electronic detonators, the market size will be about 1.3 billion yuan per year. [0003] However, the cost of solid capacitors is lower than that ...
