Description

Multifunctional anti-explosion splits the safety glass lens

Technical field

The utility model relates to a kind of lens, specifically is that a kind of multifunctional anti-explosion splits the safety glass lens.

Background technology

All in the market glass eye eyeglasses all have following multinomial shortcoming and can't generally adopt for the glasses processing industry:

1, can't be dyeed.

2, the spectacle glass of general white light material can't be resisted harmful ultraviolet light, also can only reach 380nm and can resist the special glass that is harmful to ultraviolet light wave, is not enough to satisfy the 400nm of market demand.Though new product (the Corning company production code member 8010) ability of blocking of the up-to-date release of Corning Incorporated (Corning) can reach 400nm recently, but because of the material instability, anti-oxidant and antiacid inspection performance is not good, and costs an arm and a leg, and can't be extensive use of for the glasses processing industry.

3, the weight ratio resin sheet is heavy.Cross resin sheet though optical property is superior far away, but comparatively uncomfortable.

4, must behind chemical method or high annealing method stiffened, just can pass through the resistance to fracture standard of states such as Europe, the United States, Australia, day after cutting moulding.These two kinds of stiffened methods all need professional technique and equipment, employed chemical agent has the danger of blast and the temperature of stiffened is spent between 800 degree up to Celsius 600, general glasses processing industry and optician's shop are stiffeneds voluntarily, and this also hinders the popularity rate of glass eye eyeglass.

5, just handle through stiffened at last and reach the standard of resistance to fracture, when external force collision surpasses resistance to fracture power, still can break and cause glass to scatter and injure eyeball or skin of face.

Summary of the invention

The purpose of this utility model is improved at every major defect more than the present glass eye eyeglass exactly, provide a kind of multifunctional anti-explosion to split the safety glass lens, to reach safe, the attractive in appearance and easy processing characteristics that has plastic lens concurrently, possess the optical property of the intrinsic brilliance of glass mirror simultaneously.

The technical solution of the utility model is: a kind of multifunctional anti-explosion splits the safety glass lens; Comprise anter, rear panel and resistance to fracture film, the both sides of resistance to fracture film are bonding with described anter and rear panel respectively by transparent glue, and the surface of described anter and rear panel has the chemical ion infiltration to add hard formation.

Described anter and rear panel are made by ordinary optical glass, and described stiffened pervious course is the potassium ion pervious course, and its thickness is not less than 20 microns; In described transparent glue, be added with ultraviolet light absorber.

Described ultraviolet light absorber is an aziminobenzene class medicament.

Described transparent glue is soft powerful optical grade glue, comprises epoxide resin type or polyurethane type glue.

Described resistance to fracture film is made by the multi-polyester film.

The utlity model has following several characteristics:

1, can dye: main color is from the multi-polyester film, gives fixation in the dyestuff again and can dye various needed colors as long as mylar is soaked in.During if fits, can present the full-color of film with flint glass, when fitting with coloured glass, the color that then can modify coloured glass.

2, uvioresistant: when not having anti-uv-ray or deficiency, ultraviolet light absorber can be dissolved in the glue to supply desired uvioresistant characteristic as if the glass itself that uses.

3, cut and do not need to do stiffened after the moulding again and handle: the glass eye eyeglass of applying usefulness is handled through the pyrochemistry stiffened in advance, less potassium ion (K+) is filled up space between the bigger sodion of glass (Na+) structure itself with the powerful glass internal layer that infiltrates of high temperature heat, and the material that makes skin glass is consolidation thereby improve its resistanee to rupture more.

4, thinner lighter: common eyeglass has only the two sides, so have only these two faces to provide to do the stiffened opposing to break.Because the bulge resistance deficiency so the thickness of glass mirror itself must enough thickly just can reach international resistanee to rupture standard, generally needs the above thickness of 2mm.But the attaching type eyeglass is formed by two, and one has four faces can do top layer stiffened processing.After two applyings, the impact resistance collapse strength multiplies each other, so the resistance to fracture dynamics is more than the twice of general eyeglass, must not rely on the structural strength of glass itself to supply required resistanee to rupture.Because of eyeglass according to need thickness grind, every the thinnest can be thinned to 0.6mm, still can reach the national standard of states' requirement glass eye eyeglass resistance to fractures such as Europe, the United States, Australia, day.

5, antiknock is split: when causing eyeglass to break even external force collision surpasses resistanee to rupture, eyeglass of the present invention can explosion yet.Because the glass fragment that breaks can be adsorbed by the soft glue water layer and be fixed on the multi-polyester film of inner face interlayer, be unlikely hurting eyeball or facial cortex.
