Conductive copper powder based oil paste for improved long term stability and manufacturing method thereof

摘要

The present invention relates to a copper powder-based oil-based paste with improved long-term stability and a manufacturing method. In order to prevent oxidation of copper powder and provide thermal stability and long-term stability, the present invention treats the surface of copper powder with a vinylimidazole polymer, and mixes the treated copper powder composite with an oil-based binder containing a solvent and an additive, By manufacturing a copper powder-based oil-based paste, a copper-based oil-based paste that replaces the existing conductive metal paste and can be applied to the fields of electronic circuit devices, semiconductor devices, flexible electrical and electronic devices and wearable electrical and electronic devices and a method for manufacturing the same .
