Embodiment 1
[0044] A high-refractive polymer resin lens, the preparation method of which is:
[0045] (1) Dibutyl phthalate 15%, propylene alcohol 5%, isocyanate 30%, dibutyl tin dichloride 0.3%, photocuring initiator 0.5%, methyl styrene balance by weight percentage Add it into the dosing device, stir for 1 hour at a temperature of 30°C, lower the temperature to 20°C and then stir for 0.5 hour, and mix evenly to obtain a mixed liquid material;
[0046] (2) After the mixed liquid material is filtered, use nitrogen pressurization to inject the mixed liquid material into the mold, and seal the mold;
[0047] (3) The filled mold is cured once at 55°C for 4 hours, and the cured mold is opened to separate the mold and the formed lens;
[0048] (4) Trimming the formed lens to obtain a lens with precise diameter and high-gloss edge;
[0049] (5) The repaired lens is subjected to multi-groove ultrasonic cleaning, and the cleaned lens is subjected to secondary curing treatment in a curing furnac...
Embodiment 2
[0068] The polymer resin lens with a high refractive index described in Example 1 is different in that its preparation method is:
[0069] (1) Dibutyl phthalate 20%, propylene alcohol 15%, isocyanate 40%, dibutyltin dichloride 1.5‰, photocuring initiator 3‰, methyl styrene balance by weight percentage Add it into the dosing device, stir for 1 hour at a temperature of 35°C, lower the temperature to 25°C and then stir for 0.5 hour, and mix evenly to obtain a mixed liquid material;
[0070] (2) After the mixed liquid material is filtered, use nitrogen pressurization to inject the mixed liquid material into the mold, and seal the mold;
[0071] (3) The filled mold is cured once at 55°C for 4 hours, and the cured mold is opened to separate the mold and the formed lens;
[0072] (4) Trimming the formed lens to obtain a lens with precise diameter and high-gloss edge;
[0073] (5) The repaired lens is subjected to multi-groove ultrasonic cleaning, and the cleaned lens is subjected t...
Embodiment 3
[0076] The polymer resin lens with a high refractive index described in Example 1 is different in that its preparation method is:
[0077] (1) Dibutyl phthalate 25%, propylene alcohol 20%, isocyanate 50%, dibutyl tin dichloride 0.5%, photocuring initiator 1.0%, methyl styrene balance by weight percentage Add it into the dosing device, stir for 1 hour at a temperature of 40°C, lower the temperature to 30°C and then stir for 0.5 hour, and mix evenly to obtain a mixed liquid material;
[0078] (2) After the mixed liquid material is filtered, use nitrogen pressurization to inject the mixed liquid material into the mold, and seal the mold;
[0079] (3) The filled mold is cured once at 70°C for 3 hours, and the cured mold is opened to separate the mold and the formed lens;
[0080] (4) Trimming the formed lens to obtain a lens with precise diameter and high-gloss edge;
[0081] (5) The repaired lens is subjected to multi-groove ultrasonic cleaning, and the cleaned lens is subjecte...
