A kind of dark brown resin lens and manufacture method thereof with visible ray discoloration
[technical field]
The present invention relates to dark brown resin lens technical field, specifically, is a kind of dark brown resin lens and manufacture method thereof with visible ray discoloration.
[background technology]
The common resin lens with discoloration, have in ultraviolet situation can variable color outdoor, but in indoor or car, have visible ray but under the less condition of ultraviolet ray, substantially can not variable color.In a large amount of computers and the use procedure of display screen, blue light can cause certain injury to people's eyes, and spectacles industry has been designed the various eyeglasses with anti-blue light effect according to client's demand.Arrive winter, often has dense fog to occur, if increase the contrast of vision, is again the requirements at the higher level that glasses are proposed.The present invention seeks to a pair of glasses and solve three kinds of above problems, a kind of dark brown resin lens manufacture method with visible ray discoloration is provided.Adopt novel composition of raw materials, increase multiple UV absorbing agent in Raw materials for lenses, eyeglass can absorb a large amount of 450nm with interior light, a large amount of blue lights of filtering.In composition of raw materials, increase weld, can improve wearer's visual contrast and sharpness.Even the also recognition object preferably of wearer in serious or foggy situation in air pollution.Add visible ray toner, under the sufficient condition of visible ray, this eyeglass can part variable color, and the transmitance of eyeglass can be reduced in 50%; Under strong sunlight, the variable color completely of this eyeglass, its transmitance can be reduced to 25%, has good filter effect.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art, a kind of dark brown resin lens and manufacture method thereof with visible ray discoloration is provided.
The object of the invention is to be achieved through the following technical solutions:
A dark brown resin lens with visible ray discoloration, the mass percent of its feed composition is:
Described UV agent, be 2 '-(the 2 '-hydroxyl-3 '-tert-butyl group-5 '-aminomethyl phenyl)-5-chlorobenzotriazole or and 2-(2 '-hydroxyl-5 '-tertiary octyl phenyl) benzotriazole and ESCALOL 567 and 2,2 '-dimethyl-4-methylamino benzophenone, the ratio of four kinds of UV agent is 1: 2: 2: 3, and consumption is 0.02~0.5 ‰.
Described weld comprises metal complex class dyestuff benzidine yellow or condensation azophosphine, and consumption is 0.01~0.04 ‰.
Described visible ray toner is the polymethacrylate with spiropyran groups, and consumption is 0.05~0.8 ‰.
A manufacture method with the dark brown resin lens of visible ray discoloration, its concrete steps are:
After filtering with the filter disc of 0.5 μ m according to above-mentioned formula gained potpourri, be poured in preprepared glass mold, put into baking oven, according to program curing below, carry out Raolical polymerizable;
While reaching 70 ℃, remove mould, gained resin lens can be obtained after edging, cleaning and strengthening to the dark brown resin lens with visible ray discoloration.
According to the dark brown resin lens with visible ray discoloration of production program gained, original transmitance is greater than 80%, and the in the situation that of only having visible ray in car, transmitance is down to below 50%, and transmittance can be down to below 25% after ultraviolet ray or solar light irradiation, there is good filter effect.In eyeglass formula, increase multiple UV absorbing agent, eyeglass can absorb 450nm in a large number with interior light, a large amount of blue lights of filtering.In composition of raw materials, increase weld, can improve visual contrast and sharpness, the recognition object preferably in serious or foggy situation in air pollution.
Compared with prior art, good effect of the present invention is:
In lens materials, increase multiple UV absorbing agent, eyeglass can absorb a large amount of 450nm with interior light, a large amount of blue lights of filtering.Wear this eyeglass and will reduce the injury of blue light to glasses.In Raw materials for lenses, increase weld, can improve wearer's visual contrast and sharpness.The better recognition object of wearer in serious or foggy situation in air pollution.Add visible ray toner, under the sufficient condition of visible ray, this eyeglass can part variable color, and eyeglass transmitance can be reduced in 50%; Under sunburst, the variable color completely of this eyeglass, its transmitance is reduced to 25%, has good filter effect.
