Problems solved by technology

The inactive diluent currently used does not participate in the reaction, but it is highly volatile, has a strong odor, is easy to sensitize, has large toxic and side effects, and has a corrosive effect on the metallized film, which affects the service life of the capacitor.
Some active diluents can be used, but they are prone to allergies, are volatile, or have poor dilution effects
The performance of the prepared epoxy resin material used for fixing the sealing core package is relatively poor, which brings great trouble to the user

Abstract

The invention provides a material for fixedly sealing the core packet of a capacitor and a preparation method thereof, and relates to the technical field of capacitor production. The material for fixedly sealing the core packet is prepared from, by weight, 45-55 parts of epoxy resin, 9-11 parts of alkyl glycidyl ether, 90-110 parts of an auxiliary material, 12-16 parts of a flame retardant, 4-8 parts of a toughening agent and 3-5 parts of a curing agent. The defects of the prior art are overcome, the dilution effect of the epoxy resin can be effectively improved, and the obtained material forfixedly sealing the core packet is odorless, not prone to volatilization or sensibilization and free of toxic or side effects at room temperature, can participate in reaction of the curing agent, doesnot corrode metallized films, and is good in curing effect, excellent in performance and long in service life.

Description

technical field [0001] The invention relates to the technical field of capacitor production, in particular to a material for fixing and sealing a core package of a capacitor and a preparation method thereof. Background technique [0002] A capacitor is composed of a layer of insulating dielectric sandwiched between two metal electrodes. When a voltage is applied between two metal electrodes, charges are stored on the electrodes, so capacitors are energy storage elements. Any two conductors that are insulated from each other and in close proximity form a capacitor. A parallel plate capacitor consists of the plates of the capacitor and the dielectric. Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control, etc. in circuits. [0003] CBB61 and CBB60 capacitors generally use epoxy resin as the material used to fix the sealed core package. Du...
