Description
Technical field
The present invention relates to rubber composite manufacture field, particularly a kind of capacitor special (purpose) rubber sealing ring andPreparation method.
Background technology
Capacitor, conventionally referred to as electric capacity, is one of a large amount of electronic components that use in electronic equipment, extensive useIn circuit every aspects such as straight-through friendship, coupling, bypass, filtering, resonant tank, power conversion, controls. ElectricityContainer is made up of housing, capacitor core, end cap and binding post, and steeping medium is housed in capacitor casing, soaksStain medium is generally vegetable oil or mineral oil, and the sealing position of capacitor is equipped with sealing gasket or sealing ring, due toThe working environment of capacitor varies, and some capacitors need to be worked under rugged environment, capacitor sealingPad needs high temperature resistant, cold-resistant, acid and alkali-resistance, salt spray resistance etc. to have different requirements.
Summary of the invention
