LASER TRANSMISSION BONDING METHOD OF TRANSPARENT PLASTIC

摘要

A laser transmission bonding method of a transparent plastic is provided to improve the bonding strength by bonding only a bonding portion with laser. A laser transmission bonding method of a transparent plastic includes the steps of: preparing an upper transparent plastic and a lower transparent plastic which are to be bonded to each other(S1); coating an absorption body coating liquid on a bonding portion of one of the transparent plastics(S2); and bonding the upper and lower transparent plastics by illuminating laser beam to the bonding portion of the transparent plastic and melting the coated portion with an absorption body.
