Abstract

The invention provides gray green sunglasses glass suitable for lattice-method process production, which comprises a basic glass part and a colorant part, wherein the basic glass part comprises the following components: 66 to 75 weight percent of SiO2, 10 to 20 weight percent of Na2O, 5 to 15 weight percent of CaO, and 1 to 4 weight percent of Al2O3; and the colorant part comprises the following components: 0.2 to 1.0 weight percent of Fe2O3, 0.03 to 0.2 weight percent of CoO, 0.2 to 0.8 weight percent of Cr2O3, 0.08 to 0.8 weight percent of NiO, 0.2 to 2.0 weight percent of CeO2, and 0.5 to 4.0 weight percent of TiO2. The glass of the invention is gray green; the visible light transmittance T of the glass is 8 to 40 percent; the UVB transmittance of ultraviolet spectral regions is less than or equal to 5 percent and is less than or equal to 0.5T; and the UVA transmittance of the ultraviolet spectral regions is less than or equal to T. Therefore, the glass can meet the technical requirements of sunglasses glass. The Fe2O3 content of colorant in the glass is 0.2 to 1.0 weight percent, and is applicable to lattice-method process production.

Description

Be suitable for the gray green sunglasses glass that lattice-method process is produced
Technical field
The invention belongs to the colored glass field, it is low to be specifically related to a kind of ultraviolet transmittance, be suitable for that lattice-method process produces gray green sunglasses glass.
Background technology
Wearing sun glasses is that people protect eyes to avoid the main means that high light stimulates.Ultraviolet ray is well-known to the injury of human eyes, is in for a long time in the high light environment, causes eye illnesses such as acute keratitis, conjunctivitis, chronic cataract easily.Because the color of sun glasses is very dark, the pupil of wearing the back human eye can amplify, so require sun glasses ultraviolet ray projection ratio very low.Otherwise wear sun glasses and not only can not protect eyes, bring injury to human eye on the contrary.
The existing ultraviolet ray intercepting glass producer is for making the ultraviolet ray of glass strong absorption, and general iron content is (with Fe 2O 3Meter) up to 1.0%～3.0%, but the iron in the glass absorbs the ultraviolet while, equally also strong absorption infrared rays, and this just makes the diathermancy of glass very poor.Because the color of sunglasses glass is very dark, and transmission of visible light 8%～40% during thickness 1.5mm, and diathermancy is further reduced, bring the difficulty that is difficult to overcome for the fusing and the shaping of glass simultaneously.So sunglasses glass generally needs electrofusion or the auxiliary electrically heated dedicated melting kiln of band, can not produce on sophisticated lattice normal.In lattice-method process, the iron oxide content in the glass is generally less than 1.0%.Otherwise too high ferric oxide reduces the diathermancy of glass rapidly, fusing difficulty not only, and cause cooling end and working chamber's temperature too low, and the forward and backward lip tile position temperature difference is too big, and the buttress shakiness can not normally be shaped.
At present, colored glass more and more is subjected to people's favor, has shielding of ultraviolet and infrared function, and grey that transmission of visible light is low and green glass have been applied on building and the vehicle.All provided such as 93114463.9,03117080.3 etc. and to be suitable for dull and stereotyped production technique, the ultraviolet green glass of strong absorption is formed.But when these glass are converted into the glass of thickness 1.5mm, ultraviolet transmittance all greater than 40%, can not satisfy the requirement of sun glasses to ultraviolet cutoff.And the content of ferric oxide is not suitable for lattice-method process production up to 1.0%～1.6% in the glass.
Summary of the invention
The objective of the invention is to solve existing grey ultraviolet ray intercepting glass thickness and be not suitable for use in sunglasses glass greatly, if make the suitable thickness of sun glasses, glass transmission of visible light, ultraviolet transmittance are all too high, do not reach the requirement of sunglasses glass, or because the too high influence of iron level in the glass to glass melting and shaping, be not suitable for the technical problem of lattice-method process, provide a kind of low iron content, ultraviolet transmittance low, be suitable for the gray green sunglasses glass of lattice-method process.
The objective of the invention is to be achieved through the following technical solutions:
The gray green sunglasses glass that is suitable for lattice-method process production of the present invention comprises parent glass part and tinting material part, and parent glass partly comprises following component:

Described parent glass part also comprises the MgO of 0.01～5wt%.The parent glass part also comprises the K of 0.01～4wt% 2O.
Described tinting material also comprises the Se of 0.01～0.2wt%.
Described thickness of glass is 0.8mm～3mm.
Glass of the present invention is particularly suitable for lattice-method process production, also is suitable for other technologies such as float glass process, vertical drawing simultaneously.
Compare with prior art, beneficial effect of the present invention is as follows: (1) glass transmission of visible light of the present invention T is 8%～40%; UV spectrum district UVB transmittance≤5%, and≤0.5T, UV spectrum district UVA transmittance≤T can satisfy the technical requirements of sunglasses glass.(2) tinting material Fe among the present invention 2O 3Content be 0.2～1.0wt%, be applicable to lattice-method process production; (3) glass colour is a greyish-green, and the thickness of glass is 0.8mm～3mm, is applicable to make sun glasses or ultraviolet ray intercepting glass is made in other field.
