Description
Technical field
Present invention relates particularly to preparation method and the product of a kind of variable color wear-resisting automatically cleaning concave lens.
Background technology
The most domestic material as lens mainly has a three major types: spar, optical glass and optical resin.Compared with optical glass, optical resin lens has the advantages such as light weight, shock resistance and easy machine-shaping, and once release, instead of optical glass soon becomes the main product of lens.
American invention in 1964 photo chromic glass.The color-changing lens of high-quality should be transparent, and without emulsifying color and luster, the time of partly recovering lost eyesight is short, recovers lost eyesight fast.The original transmitance of color-changing lens without primary colours is up to about 90%.The original transmitance of color-changing lens having primary colours can as little as 60~70%.Transmitance after general sun mirror-type color-changing lens light color is reduced to 20~30%.The color-changing lens variable color of comfortable type is shallower, the transmitance 40~about 50% after light color.
Antistatic coating is the main application market of nano ATO (Antimony Tin Oxide) powder.ATO nanometer ultramicron powder body, with the transparent conductivity of the non-resistive in semiconductor applications, there is the most excellent antistatic property, and can effectively intercept infrared and ultraviolet radiation, and nano ATO particle is the most weak to the absorbance of visible ray so that it is have the good transparency.Can be applicable to various anti-static plastic, coating, fiber, transparent heat insulating dope, display antiradiation coating, solaode, automotive windshield etc..And various resin plays transparent, conduction, antistatic radiation, every ultraviolet and infrared effect.
Within 1971, first Aisenberg and Chabot report, obtains a kind of physical and chemical performance hard carbon film approximating or similar to diamond under room temperature condition, their named diamond like carbon (DLC) film.Diamond like carbon (DLC) has graphite-structure sp2 key and diamond lattic structure sp3 key, so
DLC has the good characteristic that some are similar to diamond thin, and such as high rigidity and highly thermally conductive property, wide optics passes through scope (refractive index is generally 1.5-2.6) and good electric property (resistivity is up to 1000 cm), biocompatibility etc..There is the performance being different from diamond thin, such as film-forming temperature low (can as little as room temperature) simultaneously, the features such as surface smoothness is high, good friction and wear behavior (coefficient of friction as little as less than 0.2).Diamond-film-like has high rigidity and high elastic modulus, and DLC film hardness prepared by different deposition process is widely different, and DLC film has the wearability of excellence, low-friction coefficient, is the surface abrasion Modified Membrane of a kind of excellence.
Having had the research much about self-cleaning glass at present, they technology used are the most all the films containing titanium dioxide at glass surface plating last layer, and when solar irradiation is above, organic dirt above will be degraded, and then reaches light-catalysed purpose.But this technology is difficult to use on glasses, because eyeglass is resin, being organic high molecular polymer, and titanium dioxide is as a kind of widely used photocatalyst, it but has the biggest shortcoming: its photocatalytic degradation does not have selectivity.If being applied on glasses, then it is likely to decompose the structural component of eyeglass.So finding a kind of photocatalyst with suitable selective and to be applied to the plated film film layer of eyeglass the most necessary.
