Description
Technical field
The present invention relates to binder material field, be specifically related to a kind of ageing-resistant binding agent of bi-component and preparation method thereof.
Background technology
Conventional bonding agent can simply be divided into single component adhesive and double-component bonding agent, and industry is also commonly called as one-component one
Liquid type and double-component two-liquid type bonding agent.One-component one liquid type bonding agent is dependent on effect and the contact surface generation thing of Van der Waals force
Reason effect and bonding force is provided；Double-component two-liquid type bonding agent is that the chemical reaction between group provides bonding force.As can be seen here,
The adhesive bond intensity of double-component two-liquid type is higher；Further, the tack of double-component two-liquid type bonding agent is also than one-component one
The tack of liquid type bonding agent is good.
Along with microelectronic fast development, electronic devices and components are more and more less, and the use of integrated electronic modules gets more and more, heat
The continuous application of sensitive materials, needs the highest adhesion strength when not requiring nothing more than assembling, also require to need less than 60 DEG C when assembling
The binding agent of solidification temperature.In electron trade, conventional binding agent is dual-component binder and UV solidification binding agent, due to
UV solidification binding agent easily infiltrates into electronic devices and components inside and causes unexposed UV solidification binding agent cannot be irradiated to UV light, and
Cause adhesion strength inadequate, affect service life.Dual-component binder at 60 DEG C of fast setting, and can reach certain bonding
Intensity, but surface drying time is long, affects production efficiency and yield, and its resistance to ag(e)ing, water resistance are the best, and impact uses
Life-span.
