Description

A kind of spectacle lens made of resin and manufacture craft thereof
Technical field
The present invention relates to a kind of optical material, specifically a kind of glasses lens and manufacture craft thereof, especially a kind of spectacle lens made of resin and manufacture craft thereof.
Technical background
Current spectacle lens made of resin since have in light weight, transparency is high, shock resistance, easy-formation, can dye, characteristics such as anti-ultraviolet, in the glasses market competition, be in preferential status.Because get the rising of the colony of cataract illness in the last few years, the function and the effect of the antiultraviolet of eyeglass are more and more paid attention to.Domestic production and the maximum spectacle lens made of resin of sale, its prescription major ingredient comprises: CW-55 (glycol ether propenyl two carbonic ethers), CR-39 (glycol ether propenyl carbonic ether), UV-5411[2-(2 '-hydroxyl-uncle's 5-octyl phenyl) benzotriazole], mineral dye and IPP (di-isopropyl peroxycarbonates), its anti-ultraviolet property desired value is UV360-370nm.Existing production and selling also has a kind of eyeglass: CW-55 (glycol ether propenyl two carbonic ethers), CR-39 (glycol ether propenyl carbonic ether), UV-5411[2-(2 '-hydroxyl-uncle's 5-octyl phenyl) benzotriazole], mineral dye and IPP (di-isopropyl peroxycarbonates), actual cutoff wavelength also has 15% transmitance at 400nm.Because ultraviolet ray (UV) arrives in the light of earth surface, the distinguishable wavelength of light of human eye is 380nm-760nm, and wavelength region is ultraviolet ray at the light of 10nm-380nm.Ultraviolet ray is divided into UV-A again: the ultraviolet ray of wavelength 315-400nm according to the wavelength difference; UV-B: the ultraviolet ray of wavelength 280-315nm; UV-C: the ultraviolet ray of wavelength 100-280nm.Proof: UV-A is received the back by the crystalline of eyeball and easily produces cataract after deliberation; UV-B easily causes keratitis after being absorbed by cornea, and cornea is suffered damage; UV-C is absorbed by ozonosphere, almost can not the arrival point face, the people is influenced not quite.Existing spectacle lens made of resin is uvioresistant fully, and commonly thinks: the ultraviolet ray of wavelength 315-400nm is received the back by the crystalline of eyeball, and to produce cataract, especially wavelength be the ultraviolet ray of 370-400nm.World environments is polluted aggravation now, destruction to ozonosphere is increasingly sharpened, the ultraviolet ray amount that is radiated the face of land increases, in all trades and professions, all more or less relate to simultaneously some uviolizings, as the cash inspecting machine of banking industry, manufacturing electric welding cutting, breadboard ultraviolet sterilization is provided with or the like, health of the human eyes of serious threat all, the eyeglass that helps people's eye health is the target that people pursue.
Summary of the invention
Above-mentioned defective at prior art the invention provides a kind of spectacle lens made of resin, and it can intercept all following ultraviolet rays of 400nm fully, reduces the direct and consequential injury to glasses.Another object of the present invention provides the manufacture craft of aforementioned eyeglass.
In order to reach above purpose, the present invention realizes by following technical solution: a kind of spectacle lens made of resin, it mainly includes glycol ether propenyl two carbonic ether Brite-55, glycol ether propenyl carbonic ether RAV7AT, 2-(2 '-hydroxyl-uncle's 5-octyl phenyl) benzotriazole UV-5411, mineral dye B, mineral dye A, di-isopropyl peroxycarbonates IPP, diphenylethyllene dibenzoxazine UV-0, the weight percent of its each component is: Brite-55:50-95%, RAV 7AT:0-48%, UV-5411:0.1-0.2%, ultraviolet absorbers UV-41:0.1-0.2%, mineral dye B:0.3-0.4%, mineral dye A:0.3-0.4%, IPP:1-3.5%, the two benzothiazole UV-0:0.01-0.5%{Brite-55 of diphenylethyllene, UV-5411, mineral dye B (inorganic blue pigments), mineral dye A (inorganic red pigment) supplier is Korea S bucket mountain Co., Ltd.; RAV 7AT supplier is a U.S. big lake chemical industry company limited; Ultraviolet absorbers UV-41, the two benzothiazole UV-0 suppliers of diphenylethyllene are Korea S KOC company }.
The manufacture craft of a kind of spectacle lens made of resin of the present invention comprises that batching, filling curing, substrate are handled, secondary melts down, the eyeglass treatment process, and it is characterized in that: described filling is cured as segmentation control, and segmentation controlled temperature and time are shown in the table 1:
Table 1 segmentation controlled temperature and time
Temperature T (℃) 33≤T＜35 35≤T＜45 45≤T＜60 60≤T＜85 85 85＜T≤75
Time 2 hours 4 hours 8 hours 3 hours 2 hours 1 minute
Further improving of a kind of spectacle lens made of resin manufacture craft of the present invention is: it is 118-122 ℃ that described secondary melts down temperature.
The present invention adopts multiple UV light absorber to be used, and UV light absorber discharges by energy such as the heat energy that ultraviolet absorption is changed into other, reaches each wave band of ultraviolet ray and evenly and effectively absorbs.
Because the present invention has adopted above technical scheme; spectacle lens made of resin provided by the present invention; its ultraviolet resistance has reached the royal purple light that intercept all following ultraviolet rays of UV400nm and 400-420nm fully, the effectively protective spectacles royal purple light stimulus that is not subjected to ultraviolet infringement and dazzles the eyes.The present invention is particularly suitable for the geographic personnel of industrial welding place, bank, ultraviolet disinfecting action chamber, plateau and tropical and subtropical zone and uses.
