Description
Technical field
The present invention relates to a kind of lens, particularly to a kind of color-change resin lens and preparation method thereof.
Background technology
Resin lens passes through the case hardness that surface stiffened can reach similar to glass lens, and surface can resistance to be cleaned repeatedly, can improve lens surface impact resistance to a certain extent simultaneously；A piece of perfection adds the formation of stiff sheet, need the conditions such as clean room environment, supersonic wave cleaning machine, indoor positive pressure, with ensure eyeglass during stiffened not by environment and air pollution, otherwise in solution and air, any small particles can affect the quality of eyeglass.After a series of cleaning procedures, resin lens enters baking oven post-drying, enters back into hardening liquid stiffened, tests after drying, qualified after place into baking oven and fully solidify, ready for next step warehouse-in or plated film.During whole stiffened, the dustless cleaning of environment to be ensured, the absolute cleanliness of resin lens to be ensured, it is necessary to ensure that not bringing the various additives that impurity, eyeglass can not dissolve in impurity, i.e. eyeglass during stiffened into can not be dissolved by hardening liquid.
Nearly 2 years, resin color-changing lens was the most rather well received, owing to having the optical property of uniqueness, and had light weight, impact resistance and the good characteristics such as non-friable.Due to this eyeglass color changeable effect, the eyeglass after outdoor variable color can effectively filter harmful ultraviolet light and blue light, can recover again normal colour of lens in indoor, therefore, it is possible to preferably protect eyesight.
Research proves, common sunglasses can pass through ultraviolet light, the cornea of the fragile eyes of this ultraviolet light and crystalline, cataract, macular degeneration, angle myositis and corneal degeneration etc. can be caused, damage eyeground and cause yctalopia, additionally the cutaneum carcinoma more than 90% all occurs in head zone, and eyes skin over-exposure sunlight may cause cutaneum carcinoma；The blue light that common sunglasses can also not focus on through a part on human eye retina, this blue light is to be formed due to Particle Scatterings such as the cigarette in air, mist, snowflakes, it is exactly additionally from various LCD screens, mobile phone, computer, flat board and television set, absorbed after entering human eye, retina can be damaged for a long time.Color-changing lens not only indulges in luxuriousness to one's heart's desire while outdoors sunlight for people, brings health to eyes, the most also will wear light-sensitive glasses and incorporate a part for life.
But under normal circumstances, after resin color-changing lens makes shaping, having a large amount of abrasion in follow-up milling and abrasive disc, this had both wasted raw material and had used, had wasted a large amount of color-change powder, and this part waste material is also difficult to recycle, and causes secondary environmental pollution simultaneously.This causes to a certain extent, and production efficiency is the lowest, cost is high；And due to eyeglass cure profile and the impact of lens materials, the control more difficult to temperature, time and additive concentration of variable color technique, cause defective work to remain high always, current ameliorative way has:
1, gathering variable color: i.e. eyeglass introduces color-change powder in the course of the polymerization process, but color-change powder and polymer are at whipping process, if disperseing or emulsifying bad, can be filtered out by PP filter core in the filtration before raw material solidifies.The whole eyeglass of this technique is filled with the variable color factor, the color-changing lens worked it out, and uniform coloring is not so well, and the color change under shortwave wavelength is slow, and the variable color degree of depth is the most not so well, and under indoor conditions, resume speed is slow, and variable color is the most lasting.This technique is simple comparatively speaking, but the bad control of lens quality worked it out.
2, film laminar variable color: a layer that eyeglass teleblem is the thinnest is the variable color factor, the eyeglass in this case worked it out, the variable color degree of depth is good, and color change is very fast, variable color uniformity is also preferable, but technique mixes the more complex of formula relatively, and film layer variable color persistence is not so well.
Accordingly, it is now desired to develop a kind of stable film layer color-change resin lens and preparation method thereof.
Summary of the invention
The technical problem to be solved in the present invention is, for existing deficiency, it is provided that a kind of high-quality, antiultraviolet and the color-change resin lens of blue light.
