Abstract
The present invention provides a glass component which can be used for effectively blocking ultraviolet rays and has high visible light transmissivity. On the basis of common float glass, the following components which are proportioned by weight are added: 0.7% to 1.2% of iron (Fe2O3), 0.8% to 1.5% of cerium (CeO2), 0% to 0.6% of titanium (TiO2), and 2 ppm to 15 ppm of cobalt (Co3O4). The thickness of the melted glass is 4mm, the visual light transmissivity is larger than 70%, and the ultraviolet ray transmissivity is smaller than 10%.
Description
Technical field
The present invention relates to a kind ofly have high visible light transmissivity and the very low sheet glass of ultraviolet ray transmissivity, this kind glass can be widely used in automobile wind shield glass and other need reduce the field of ultraviolet ray transmissivity.
Technical background
The development with Domestic Automotive Industry of improving constantly along with people's living standard, increasing family has the private savings automobile, the most of transparent glass that adopts of the windshield that present automobile is used, has a higher ultraviolet ray transmissivity and transparent glass is general when having than high visible light transmissivity, too many uviolizing is in automobile, can cause driver and crew's skin on the one hand and burn, can quicken the aging of automobile interior trim material on the other hand, therefore, adopting the windshield glass with low ultraviolet ray transmissivity is the direction of vehicle glass development from now on.
The shine ZL03117080.3 patent of magnificent Pilkington glass limited-liability company application of Chinese Shanghai, related to a kind of " absorbing ultraviolet and infrared green glass by force " by name, the visible light transmissivity of this kind 4mm glass is 70～75%, and ultraviolet ray transmissivity is 15～20%.
Summary of the invention
In order further to reduce the ultraviolet ray transmissivity of sheet glass, the invention provides the sheet glass of a kind of high visible light transmissivity and low ultraviolet ray transmissivity; This glass is in following common sheet glass:
Silicon oxide sio
2: 65～80%
Sodium oxide Na
2O:10～15%
Calcium oxide CaO:5～15%
Magnesium oxide MgO:2～8%
Aluminium oxide Al
2O
3: 0～3%
Potassium oxide K
2O:0～3%
Add following several components of calculating according to weight percent again:
Ferric oxide Fe
2O
3: 0.7～1.2% (wherein with Fe
2O
3The FeO of expression accounts for 10～30% of total iron);
Cerium oxide CeO
2: 0.8～1.5%
Titanium oxide TiO
2: 0～0.6%
Cobalt oxide Co
3O
4: 2～15ppm
Melt the glass that according to above-mentioned composition and have 70～78% visible light transmissivity LTA and 5～10% ultraviolet ray transmissivity TUV during for 4mm at nominal thickness, color presents light green, is expressed as with CIE-LAB: a
*=-7 ± 10, b
*=4 ± 10, L
*=85 ± 10.
Perhaps add:
Component is total iron Fe of 0.8～1.2% by weight percentage
2O
3, wherein with Fe
2O
3The FeO of expression accounts for 10～30% of total iron, and 1.0～1.5% cerium CeO
2, 0.2～0.5% titanium TiO
2Cobalt Co with 4～10ppm
3O
4
Melting the visible light transmissivity (LTA) of glass when nominal thickness is 4mm that according to above-mentioned composition and have 70～75% visible light transmissivity and 6～9% ultraviolet ray transmissivity (TUV), present light green, is not a with the CIE-LAB table
*=-7 ± 4, b
*=4 ± 4, L
*=86 ± 5.
Advantage of the present invention is, under the prerequisite that guarantees the driver safety sight line, greatly reduce solar ultraviolet to the radiation in the car, avoided sunlight middle-ultraviolet lamp burning and reduced the aging speed of upholstery material to driver and crew, and with respect to transparent glass, glass provided by the present invention can also reduce ultrared radiation greatly, helps the reduction of automobile energy consumption.
Embodiment
According to component preparation admixtion provided by the invention, add in the glass melter and melt, and elimination bubble and inclusion wherein, be cooled to then about 1000～1200 degree, allow glass flow on the metallic tin of molten state again and carry out moulding, be drawn into required thickness and width with stretcher, final glass enters in the annealing furnace and eliminates stress.
In the process of visible light transmissivity, ultraviolet ray transmissivity and the color of measuring glass, adopt method and the data calculated that is provided among the ISO9050 " mensuration of building glass visible transmission ratio, the direct transmittance of sunlight, total solar energy transmittance, the when relevant window glass parameter of ultraviolet (uv) transmission ".
The present invention adds ferric oxide (Fe on the basis of ordinary plate glass composition
2O
3), cerium oxide (CeO
2), titanium oxide (TiO
2) and cobalt oxide (Co
3O
4) wait and realize above-mentioned functions.Ferric oxide in the glass has two kinds of forms usually, and a kind of is Fe
2O
3(or be expressed as Fe
3+), a kind of FeO of being (or is expressed as Fe
2+), Fe
2O
3Have the ultraviolet ability of absorption, it also can become glass coloring " yellow-green colour ", FeO to have the ultrared ability of absorption, and it can become glass coloring " blue-greenish colour ".Except that specifying, the iron in the glass is with ferric oxide (Fe among the present invention
2O
3) amount represent, but be not iron in glass only with Fe
2O
3Form exist.
Cerium oxide and titanium oxide all have the function of shielding of ultraviolet, a spot of cerium oxide can also increase the visible light transmissivity of glass simultaneously, if and the content of cerium oxide surpasses 1.5% in the glass, glass can deepening occur and influence its transmitance, especially when the long exposure in sunshine, the prolongation that the visible light transmissivity of glass can be in time and reducing.Should avoid in glass, adding more titanium oxide and cerium oxide simultaneously, otherwise glass can be by yellowly as far as possible.
Cobalt oxide is smaller to the influence of ultraviolet and infrared transmittivity in glass, and it mainly is to make glass present blueness, plays the purpose of adjusting glass colour.
