Description
Technical field
The present invention relates to a kind of silver paste more particularly to a kind of strong attached type conductive silver pastes.
Background technique
Electrocondution slurry is as a kind of functional print material because its good physical property obtains extensively in electronics and IT products
Application, as electronic product develops to lighter, thinner, functional more powerful and more environmentally friendly direction, to its performance it is also proposed that
Higher requirement.Wherein low temperature Halogen conductive silver paste is widely used in film because of its excellent electric conductivity, thermal conductivity and practicability
Switch, capacitance electrode, touch screen etc..Low-temperature conductive silver paste be using conductive silver powder as conductive filler, with polymeric resin,
Solvent, curing agent, auxiliary agent etc. are agitated, disperse and manufactured uniform sizing material.After conductive silver paste is coated on substrate, in low temperature ring
(generally below 160 DEG C) are dried under border, after solvent release, resin and curing agent step-reaction, solidification ultimately form densification
Conductive film layer.
In electronics industry, in order to meet high intensity, the high-mechanical property demand of product, after low-temperature conductive silver paste solidification
Conductive film layer generally has mechanical requirement (film hardness, film layer and substrate adhesive force etc.).Conductive silver powder is metal-powder, firmly
Spend relatively high, but the hardness of the high polymers such as resin is then general poor.And existing conductive silver paste does not have adhesive force.
Summary of the invention
Present invention seek to address that drawbacks described above, provides a kind of strong attached type conductive silver paste.
In order to overcome defect present in background technique, the technical solution adopted by the present invention to solve the technical problems is:
Component including following mass parts: flake silver powder 60-72%, nano-scale silver powder 1-10%, thermoplasticity polyimide resin 14-
19%, vanillic aldehyde 30%~50% and triterpenoid saponin 0.6-1%.
According to another embodiment of the invention, further comprise flake silver powder 72%, nano-scale silver powder 10%, heat it is plastic
Property polyimide resin 19%, vanillic aldehyde 50% and triterpenoid saponin 1%.
According to another embodiment of the invention, further comprise flake silver powder 60%, nano-scale silver powder 1%, heat it is plastic
Property polyimide resin 14%, vanillic aldehyde 30% and triterpenoid saponin 0.6%.
According to another embodiment of the invention, further comprise flake silver powder 68%, nano-scale silver powder 8%, heat it is plastic
Property polyimide resin 16%, vanillic aldehyde 35% and triterpenoid saponin 0.8%.
The beneficial effects of the present invention are: the present invention designs uniqueness, rationally, preparation is convenient for composition, with excellent electric conductivity
Can, and have very much adhesive force.
