Description
Technical field
The present invention relates to a kind of uvioresistant optical mirror slip formula and its manufacture crafts.
Technical background
With the development of science and technology, the progress that the technology of preparing of optical mirror slip is also advanced by leaps and bounds, from initial
Crystal natural lens arrive artificial synthesized glass lens, then various resin optical material eyeglasses by now, prepare the original of spectacle lens
Expect more extensive.At the same time, the function of spectacle lens is also more enriched and is promoted, and is corrected defects of vision from initial, to such as
Modern anti-blue light, UV resistance, antifatigue etc..
Nowadays the optical resin material used mainly has heat cured two carbonic ester of allyl diglycol (trade name CR-
39), unsaturated polyester (UP), polyurethanes, it is thermoplastic to have methyl methacrylate (PMMA), polycarbonate (PC).From development
Status and trend see that the polyurethane of CR-39, refractive index 1.56,1.60,1.67 that heat cured refractive index is 1.50 are especially heavy
It wants.
Above-mentioned CR-39 monomer is in a liquid state, polymerizing curable under conditions of heating and initiator.The refractive index of Cheng Jinghou is
1.499, density 1.32, Abbe number is 58~59, has stronger shock resistance, light transmittance high, can be dyed, stiffened and plated film
