Description

A kind of optics safety glass
Technical field
The present invention relates to the optical glass field with high intensity, in particular it relates to which a kind of have high intensity, high refraction The optics safety glass of rate, low dispersion characteristics.
Background technology
Social now, the utilization of optical glass is more and more wider, is widely used in camera camera glass lens, laboratory apparatus Glass lens, flashlight safety glass eyeglass etc., it is existing in order to obtain the optics safety glass of high index of refraction, low dispersion characteristics Essentially by increasing substantial amounts of Ta in component in technology2O5, and Ta2O5Belong to expensive rare-earth oxide, substantial increase Ta2O5Production cost certainly will be increased, and existing optical glass enters to ensure to use safely toward the increased direction of intensity Row changes, that is, designs optics safety glass, but safety glass is in production easily in the feelings acted on without external mechanical power Itself ruptures under condition, namely occurs the self-destruction phenomenon of safety glass, and the main reason for producing self-destruction is due to exist in glass Small nickel sulfide stones, glass tempering rear portion nickel sulfide stones over time, the change of environment can occur crystalline state Change, cause volume to increase, inside glass trigger micro-crack, and then cause glass occur self-destruction phenomenon.
The content of the invention
The present invention is high-strength by selecting the proportioning between rational component combination and each component to have there is provided one kind Degree, high index of refraction, the optics safety glass of low dispersion characteristics, solve traditional optical glass and are easily revealed in toughening process The problem of and reduce the production cost of traditional optical glass.
To achieve these goals, the invention provides a kind of optics safety glass, by weight, the glass includes： 100-200 parts of SiO2, 7-22 parts CaO, 18-33 part MgO, 15-55 part Al2O3, 12-20 parts of Na2O, 20-70 parts B2O3, 2-17 parts of K2The MoO of O, 1-10 parts BaO, 0.5-1 part3, 1.5-2.5 parts CdO, 2-7 part La2O3、1-1.8 The Gd of part2O3, 2-3 parts of Y2O3, 1-1.5 parts of Yb2O3。B2O3It is glass network formation component, with raising glass fusible simultaneously Reduce the effect of glass transition temperature；SiO2To form the key component of glass, formed with the structural component of silicon-oxy tetrahedron Irregular contiguous network, a series of skeleton as glass, and make glass that there are premium properties, such as transparency, mechanical strength, Chemical stability and heat endurance etc., it is possible to increase viscosity when glass melting and shaping；La2O3It is to obtain optical characteristics Necessary component, the present invention in pass through Gd2O3With La2O3Coexist, the stability to form glass can be improved；To reach high refraction The effect of low dispersion, introduces Y2O3、Yb2O3, meltbility, the devitrification resistance of glass can be improved, while can also reduce on devitrification of glass Limit temperature；La2O3、Gd2O3、Y2O3And Yb2O3In, to improving glass refraction and maintaining the maximum component of stability, glass effect It is La2O3But if La is used only2O3, then sufficient stability, glass is difficult to ensure that, therefore the present invention takes La2O3、Gd2O3、 Y2O3And Yb2O3The form coexisted, can obtain the glass of the high-refractivity and low-dispersion with excellent stability, glass, simultaneously Glass not easy coloring；Introduce Al2O3The tendency towards devitrification of glass can be reduced, chemical stability and mechanical strength is improved, improves heat steady It is qualitative, the stability and chemical stability to form glass can be improved；MoO3The amount of nickel sulfide stones generation, MoO can be reduced3 Suppress the smog that glass is produced in process of production with CdO hybrid energy；CaO, MgO can reduce the high-temperature viscosity of glass metal, promote The fusing and clarification of glass metal, when temperature is reduced, can increase glass metal viscosity, be conducive to improving drawing velocity；Na2O、K2O is good Good cosolvent, reduces the year of glass metal, promotes the fusing and clarification of glass metal, moreover it is possible to which the crystallization for substantially reducing glass inclines To；BaO is as glass network modifier oxides, and it can increase refractive index, density, gloss and the chemical stability of glass.This hair It is bright to be not introduced into the Ta of costliness2O5In the case of, it is ensured that the high index of refraction of glass, low dispersion characteristics, production cost is reduced, And reduce the amount of nickel sulfide stones generation, it is suppressed that the generation of glass self-explosion phenomenon.
