According to 10 seconds~5 minutes, i.e. cross-linkable solidifying.
Compared with prior art, the beneficial effects of the present invention are:
1) UV of the present invention, which solidifies cross-linking modified polyolefin optical glue film, may replace traditional OCA and LOCA optics
Glue, when this method is bonded for touch screen and liquid crystal display, simple process, energy conservation and environmental protection, bubble-free can do over again, greatly mention
Height fitting production efficiency, reduces fitting fraction defective and production cost；
2) UV of the present invention solidify cross-linking modified polyolefin optical glue film have fast high reaction speed, high mechanical properties,
The polar group that hydrolysis generates corrosion functional sheet will not occur, weather resistance and block-water performance have OCA and LOCA without comparable
Quasi- advantage.Also have excellent translucency, caking property, thermal stability, antidetonation anti-knock properties strong simultaneously, long service life can expire
Sufficient modern touch-screen is especially vehicle-mounted, outdoor display screen, large scale touch screen are to the higher performance requirement of optical film, is more advantageous to
Touch screen industry advances.
