Description
Technical field
The present invention relates to a kind of silver paste more particularly to a kind of wear-resisting 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 when by improve in a manner of silver powder loading meet it is high hard
When degree demand, the resin of relatively small amount cannot abundant, effective coated silver, cause silver powder absorption in surface layer loosely to occur falling off existing
As.
Summary of the invention
Present invention seek to address that drawbacks described above, provides a kind of wear-resisting 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:
This wear-resisting type conductive silver paste includes the component of following mass parts: 20-40 parts of modified glass powder, 0.5-3 parts of nano-sized carbon, acetic acid are fine
