Abstract

The utility model discloses a superhard polarizing lenses of PC forms by adding dura mater, extexine, polarizing film and endosexine, and the PC material is adopted to extexine and endosexine, and polarizing film inserts and puts between extexine and endosexine and fixed and form PC polarizing lenses through the bond line, and PC polarizing lenses's thickness is the 3 -5 millimeter, pass through the surface of viscose attached to the extexine with the dura mater on, be the 450 -500 nanometer with the thickness of dura mater. The utility model discloses simple structure has ultralight, ultra -thin, super impact resistance and anti ultraviolet's advantage. The experiment test, the utility model discloses a superhard polarizing lenses of PC has 99% polarisation effect, and the superficial hardness of lens can reach 8H pencil hardness, and the luminousness is 90%, and the refracting index is 1.575, it is lighter by 57% than glass, than resin lenses light by 40%, thin 30%.

Description

The superhard polarized lenses of PC

Technical field

The utility model relates to the technical field of polarized lenses, in particular to a kind of superhard polarized lenses of PC.

Background technology

Polarized lenses is exactly the eyeglass only allowing the light of a certain particular polarization in natural light to pass. It can be got rid of and the scattered beam in filtering light beam effectively, makes light can drop into ocular vision image at the light transmission shaft of the right path, makes visual field clear and natural. Existing polarized lenses is generally increase by one layer of light polarizing film in conventional lenses to reach polarization effect.

But, the defects such as it is thicker that existing polarized lenses exists eyeglass, heavier, and surface hardness is low, and shock resistance is poor. Therefore, the present inventor specially structure for polarized lenses study, develop a kind of novel polarized lenses, to solve the deficiency of existing polarized lenses, this case thus produces.

Practical novel content

The purpose of this utility model is to provide a kind of superhard polarized lenses of PC so that it is have super light, ultra-thin, the advantage of super shock resistance and antiultraviolet.

In order to reach above-mentioned purpose, solution of the present utility model is:

The superhard polarized lenses of PC, form by adding dura mater, extexine, light polarizing film and internal skin, extexine and internal skin adopt PC material, light polarizing film is interposed between extexine and internal skin and is fixed by bonding coat and form PC polarized lenses, adding dura mater (also known as the film that resistance to wears) is attached on the outside surface of extexine by viscose glue, and the thickness adding dura mater is 450��500 nanometers.

It is 3-5 millimeter that described extexine, light polarizing film and internal skin form the total thickness of PC polarized lenses.

Described light polarizing film is for carrying out strange polarisation science and technology limited-liability company AP30-100 model film.

The described dura mater that adds is Korea S's Triapex company AT20 serial model No. film.

The described coating density adding dura mater is 0.970-0.980g/ml, and viscosity is 10-20cp, and solids content is 31-33wt%, and pH value is 8.

After adopting such scheme, the utility model structure is simple, compared with existing polarized lenses, PC material is adopted to make polarized lenses, PC material makes eyeglass have the advantage of super light, ultra-thin, shock resistance and antiultraviolet, and, add and add dura mater, substantially increase the surface hardness of eyeglass, make the super shock resistance of eyeglass.

Experiment test, the superhard polarized lenses of PC of the present utility model has the polarization effect of 99%, and the surface hardness of eyeglass can reach 8H pencil hardness, and transmittance is 90%, and specific refractory power is 1.575; Lighter than glass by 57%, lighter than resin lens by 40%, thin 30%.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the partial enlargement figure of Fig. 1.

Label explanation

Add dura mater 1, extexine 2, light polarizing film 3, internal skin 4, bonding coat 5, viscose glue 6.

Embodiment

As shown in Figure 1, the superhard polarized lenses of PC that the utility model discloses, forms by adding dura mater 1, extexine 2, light polarizing film 3 and internal skin 4.

Extexine 2 and internal skin 4 adopt PC(polycarbonate) material makes. Light polarizing film 3 is the optional strange polarisation science and technology limited-liability company AP30-100 model film that is used for specifically. Light polarizing film 3 is interposed between extexine 2 and internal skin 3, and is fixed by bonding coat 5, and forms the PC polarized lenses of Sanming City formula structure. Wherein, extexine 2, light polarizing film 3 and internal skin 4 form the total thickness of PC polarized lenses is 3-5 millimeter.

Add dura mater 1(also known as the film that resistance to wears) it is attached to by viscose glue 6 on the outside surface of extexine 2, the thickness adding dura mater 1 is 450��500nm. Add dura mater and specifically can select Korea S's Triapex company AT20 serial model No. film. The coating density adding dura mater is 0.970-0.980g/ml, and viscosity is 10-20cp, and solids content is 31-33wt%, and pH value is 8.

The utility model structure is simple, adopts PC material to make polarized lenses, makes eyeglass have the advantage of super light, ultra-thin, shock resistance and antiultraviolet, lighter than glass by 57%, lighter than resin lens by 40%, thin 30%, transmittance is 90%, and specific refractory power is 1.575, the polarization effect of 99% can be met, can effectively completely cut off harmful ultraviolet, and, add and add dura mater 1, make lens surface hardness can reach 8H pencil hardness, make the super shock resistance of eyeglass.

These are only preferred implementation of the present utility model; not to the restriction of protection domain of the present utility model; all do not produce difference in essence with the technical solution of the utility model, to the deduction or replace of above-mentioned enforcement mode, all should be regarded as falling within protection domain of the present utility model.
