RESIN COMPOSITION FOR URETHANE OPTICAL LENS HAVING EXCELLENT THERMAL RESISTANCE AND REACTIVITY
摘要
The present invention relates to a resin composition for a plastic optical lens, and more specifically to a resin composition for a urethane optical lens having high thermal resistance and high reactivity. The resin composition for an optical lens of the present invention uses an optical resin prepolymer which is obtained from a preceding side reaction of a mercapto compound and a -SH/-NCO of isophorone diisocyanate or dicyclohexylmethanediisocyanate in appropriate mole ratios. The use of isophorone diisocyanate or dicyclohexylmethanediisocyanate results in enhancement of the thermal resistance of the optical lens, and the use of optical resin prepolymer at 20~70 weight % of the total weight of the resin composition for the optical lens, elutes the adhesive from adhesive tape due to lowered reactivity which results in a higher temperature reaction thereby resolving the problems of whitening phenomenon and foaming which occur on the edge of the lens due to a leak of the liquid composition when the reaction temperature increases.
