Abstract
The utility model relates to the field of optics, and in particular relates to a color change polarized light lens. The color change polarized light lens is formed by adhering a polarized light membrane and a color change membrane to a polyamide glass with a curvature, wherein the polarized light membrane and the color change membrane are directly compounded; and the adhesion is realized by coating a layer of glue on the polarized light membrane and carrying out intramembrane injection molding. The color change membrane is a TAC (Triallyl Cyanurate) color change sheet. The polarized light membrane is a composite membrane which is formed by overlapping a TAC layer, a PVA (Poly Vinyl Alcoho) polarized light layer and a TAC layer. By utilizing the color change polarized light lens, a color change polarized light polyamide (nylon) lens which can be applied practically without the stripping is realized.
Description
Technical field
The utility model relates to optical field, more specifically relates to optical mirror slip.
Background technology
Polarized lenses is exactly only to allow the eyeglass that the light of a certain particular polarization passes in the natural light.Polarized lenses has filter action, puts on it and sees that thing can be dimmed.Impinge upon the dazzling light of the equality direction on the water surface, land or the snowfield in order to filter the sun.Color-changing lens also has person to be " sensitization eyeglass ".The chemical substance that specifically adds silver halide on the eyeglass allows the colourless eyeglass of otherwise transparent, meets strong illumination, will become colored lens, does protection, is suitable for the indoor and outdoor and uses simultaneously.In order to make eyeglass have better protection effect and the scope of application, a kind of variable color polarized lenses with polaroid effect and variable color sheet effect is applied to the Sunglasses lenses sun clips field.
Existing variable color polarized lenses has multiple implementation.To have optical mirror slip, a polarizing film and one deck light modulation variable color liquid resin pigment of curvature and form by one such as the polarization optical lens of patent publication No. 1808213; And for example the tempered glass variable color polarizing combined lens made of the 201892755U of patent publication No. is to be composited by two-layer tempered glass sheet and one deck light polarizing film, having one deck in the two-layer tempered glass sheet at least is variable color tempered glass sheet, and light polarizing film is between two-layer tempered glass sheet and form.The manufacturing of these 2 kinds of variable color polarized lenses is comparatively complicated.Therefore, prior art also proposes directly to utilize the double-deck diaphragm of light polarizing film and color-changing membrane to realize that by jetting formation process in the film of PC liquation double-deck diaphragm fits in the PC(polycarbonate) a kind of variable color polarized lenses of realizing of the complex optics of sheet.Consult shown in Figure 1, the variable color diaphragm of this variable color polarized lenses is to adopt TAC (Triafol T) variable color sheet 1 ', polarisation diaphragm 2 ' is compound film sheet, is made of stacked TAC layer 21 ', PVA (polyvinyl alcohol (PVA)) polarizing layer 22 ', TAC layer, 23 ', PC layer 24 '.Like this, the variable color diaphragm 1 ' of TAC can with the PC layer 24 ' of the TAC layer 21 ' good combination of polarisation diaphragm top layer, polarisation diaphragm 2 ' bottom then can with PC eyeglass 3 ' good combination.Variable color polarisation PC eyeglass is because poor, the poor toughness of physical stress, acid corrosion-resistant not, and therefore using has certain limitation.In addition, the method only is suitable for making the PC eyeglass, if for the manufacture of the better TR(polyamide of characteristic, be commonly called as nylon) eyeglass, problem that will demoulding obviously can't practical application.
The utility model content
The purpose of this utility model proposes a kind of variable color polarisation nylon eyeglass of can demoulding, can really use.
The technical solution of the utility model is:
The variable color polarized lenses is one to have fit on polyamide (nylon) eyeglass of curvature a polarisation diaphragm and a variable color diaphragm.
Further, described polarisation diaphragm and variable color diaphragm direct combination scribble one deck glue and realize applying by ejection formation in the film on the polarisation diaphragm.Perhaps described polarisation diaphragm and variable color diaphragm direct combination scribble on the described polarisation diaphragm and realize fitting by ejection formation in the film again after pasting one deck polyamide diaphragm behind one deck glue.
Further, described variable color diaphragm is TAC variable color sheet.
Further, described polarisation diaphragm is the compound film sheet that is made of stacked TAC layer, PVA polarizing layer, TAC layer.
Further, described polyamide eyeglass is the TR90 eyeglass.
The utility model adopts as above technical scheme, can realize a kind of real feasible variable color polarisation nylon eyeglass.It is also better that this variable color polarisation nylon eyeglass has characteristic, the toughness of preferably proof stress, acid corrosion-resistant, and this eyeglass stripping phenomenon can not occur.
Description of drawings
Fig. 1 is the structural representation of existing variable color polarisation PC eyeglass.
Fig. 2 is the structural representation of the variable color polarized lenses of embodiment 1.
Fig. 3 is the structural representation of the variable color polarized lenses of embodiment 2.
Embodiment
Now with embodiment the utility model is further specified by reference to the accompanying drawings.
Consult shown in Figure 2ly, the variable color polarized lenses of embodiment 1 is one to have fit on polyamide (nylon) eyeglass 4 of curvature a polarisation diaphragm 2 and a variable color diaphragm 1.Concrete, be by injection machine with polyamide liquation ejection formation in film realize polarisation diaphragm 2 and variable color diaphragm 1 directly fit with polyamide eyeglass 4 on lens structure.Described polarisation diaphragm 2 and variable color diaphragm 1 direct combination scribble first one deck glue 3 on the polarisation diaphragm 2, realize more reliably fitting by ejection formation in the film again.Wherein, described variable color diaphragm 1 is TAC (Triafol T) variable color sheet.Described polarisation diaphragm 2 is the compound film sheets that are made of stacked TAC layer 21, PVA (polyvinyl alcohol (PVA)) polarizing layer 22, TAC layer 23.Preferably, described nylon eyeglass 4 is to adopt the TR90 eyeglass, and EMS company produces.
Consult shown in Figure 3ly, the variable color polarized lenses of embodiment 2 is consistent with the realization principle of embodiment 1, after difference is to paste first one deck polyamide diaphragm 41, carries out penetrating in the film processing and forming again.Concrete, top layer is variable color diaphragm 1, variable color diaphragm 1 adopts TAC (Triafol T) variable color sheet, variable color diaphragm 1 and polarisation diaphragm 2 and variable color diaphragm 1 direct combination, polarisation diaphragm 2 is the compound film sheets that are made of stacked TAC layer 21, PVA (polyvinyl alcohol (PVA)) polarizing layer 22, TAC layer 23, apply one deck glue 3 at TAC layer 23, then by glue 3 bonding one deck polyamide diaphragms 41, again with the polyamide liquation in film ejection formation and realize polarisation diaphragm 2 and variable color diaphragm 1 directly fit with polyamide eyeglass 4 on lens structure.Because the polyamide eyeglass 4 of polyamide diaphragm 41 and ejection formation is same material, can merge can one, the lens structure of final realization and embodiment 1 and indifference.
In above-described embodiment, because variable color diaphragm 1 is the TAC material, the top layer TAC layer 21 of polarisation diaphragm 2 also is the TAC material, so polarisation diaphragm 2 and variable color diaphragm 1 can be directly well compound.The bottom TAC layer 23 of polarisation diaphragm 2 can fit on the surface of (realizing by ejection formation in the film) polyamide eyeglass 4 well by glue 3, thereby avoids stripping phenomenon.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
