Embodiment 1

[0030] Prepare 350 base-layer lenses, after surface treatment by alkali etching, cleaning, drying, ion beam, and gluing, inspect and close the mold, and the thickness of the mold is 1.0 mm. Take 1.9Kg of chemical monomer benzyl methacrylate and 2,4-bis[4-(formylpolyethoxy)phenyl]propane in a ratio of 6:4, and add 98.77g of 2 in turn while stirring, 4-diphenyl-4-methyl-1-pentene, then add 30mg of graying dye, after stirring evenly, add 0.6g of tert-butyl peroxyneodecanoate and 0.6g of tert-butyl peroxy-2-ethyl For tert-butyl hexanoate, after stirring for 3 hours, vacuumize at -0.095Mpa for 15 minutes. Filter casting under pressure 0.05MPa, and cure with the following curing curve:

[0031] Start temperature at 35°C for 8 hours, rise to 40°C after 14 hours, rise to 50°C after 8 hours, rise to 85°C after 10 hours, then keep warm for 4 hours, drop to 50°C after 2 hours, and then furnace after 46 hours When the temperature is 50°C, take out the tape and put it in normal temperatu...

Embodiment 2

[0033] Prepare 200 base-layer lenses, after surface treatment, check the mold closing, the thickness of the mold closing is 1.2mm. Take 1.8Kg chemical monomers benzyl methacrylate and 2,4-bis[4-(formylpolyethoxy)phenyl]propane in a ratio of 6:4, and add 100g of 2,4 -diphenyl-4-methyl-1-pentene, then add 50mg of graying dye, after stirring well, add 0.4g of tert-butyl peroxyneodecanoate and 0.4g of 2-ethylhexyl peroxide Acetate tert-butyl ester, after stirring for 4 hours, vacuumize for 15 minutes under the vacuum degree of -0.090MPa. Filter casting under pressure 0.05MPa, and cure with the following curing curve:

[0034] Start temperature at 35°C for 10 hours, rise to 40°C after 12 hours, rise to 50°C after 10 hours, rise to 85°C after 6 hours, then keep warm for 4 hours, drop to 50°C after 2 hours, and then furnace after 44 hours When the temperature is 50°C, take out the adhesive tape and put it in normal temperature water, remove the mold, take out the lens and then clea...

Abstract

This invention relates to compound light induced various optical resin lens process method, which comprises the following steps: processing basic layer lens and surface process into one mask with glass mask; weighting chemical single part into linkage transfer agent and then adding color variable dye, additive and the rigger agent composed of tertbutyl peroxyisopropyl carbonate, tertbutyl peroxyisopropyl carbonate for shaking evenly with their weight proportion as 90-98:0.01-0.05:1-8: 0.6-1.0; Injecting the matched single part into the basic lens and mode to form mask for secondary solidifying.

Description

technical field [0001] The invention relates to a manufacturing process of an optical resin lens, in particular to a manufacturing method of a composite photochromic optical resin lens. Background technique [0002] Photochromic optical resin lenses are high-grade resin lenses newly developed at home and abroad in recent years. It is a special material for making spectacle lenses among polymer materials at present. It has the unique advantages of light texture, compact molecular structure, good optical performance, and high dispersion coefficient, especially the ability to effectively prevent ultraviolet rays from changing with the intensity and color of ultraviolet rays in sunlight. . The manufacture of photochromic optical resin lenses contains high technical content, and is a high-tech domestically and internationally. At present, the production of such lenses in China has just started. At present, most of the photochromic resin lenses are fully dye-added, and there are...
