Description
Technical field
The present invention relates to the phosphate antisolar glass of a kind of anti-ultraviolet radiation, this kind of glass be widely used in optical glass and
Special glass, belongs to optical glass preparation field, can be widely applied to sunglasses, window and solaode, more has
Effect ground stops ultraviolet, adds radiation resistance.
Background technology
Phosphate glass is with P2O5Glass for main component.It is with (PO4)3 -Tetrahedron is interconnected into network mutually, has
The physical property of some uniquenesses is such as: high thermal coefficient of expansion, low glass transformation temperature and softening temperature.But it
Poor chemical stability, therefore limit their application.But, Recent study finds that phosphate glass not only may be used
There to be high thermal coefficient of expansion, and can there is good optical property, such as INFRARED ABSORPTION, ultraviolet passing.Phosphate
Glass has good development prospect using its preferable infrared absorption characteristic as antisolar glass, can be widely applied to the sun
Mirror, window etc..
At present, existing patent discloses the characteristic that phosphate glass absorption is infrared.Such as, Chinese patent
(2006101211232.8) disclosing a kind of alumina phosphate glass containing copper (II) oxide, its constituent is with weight
Amount percentages comprises: the P of 65-80%2O5, the B of 0-＜ 5.5%2O3, the Al of 4-20%2O3, the La of 0-2.1%2O3,
The Y of 0-2.1%2O3, the SiO of 0-3%2, the Li of ＞ 2-12.5%2The Na of O, 0-6%2The K of O, 0-4%2O, 0-2.5's
Rb2The Cs of O, 0-2.5%2The BaO of the SrO of the CaO of the MgO of O, 0-7.9%, 0-5%, 0-5%, 0-10%, 0-8%
The ZrO of ZnO, 0-5%2, the V of CuO and 0-0.5% of 5-15%2O5, the Sb of 0-0.3%2O3, the CeO of 0-3.0%2,
The MnO of 0-3.0%2, the Cr of 0-0.5%2O3.This kind of glass has low-down transmittance and steep near infrared region
Absorption edge, has highly uniform high-transmittance simultaneously in visual field.
So far rarely has the open phosphate glass anti-ultraviolet radiation function of patent.In existing technology, generally at silicate
Glass adds CeO2Improve its ultraviolet absorption characteristic, but silicate glass can only absorb a part of CeO2, and phosphorus
The cerium of silicate glass absorption more than silicate glass 16 times, and phosphate glass can be kept to absorb ultraviolet and just maintain
The ability of Chang Yanse.Add CeO2Phosphate glass can be widely applied to sunglasses, window and solaode, more has
Effect ground stops ultraviolet, adds radiation resistance.Therefore, exploitation has purple extraradial phosphate glass and has important
Meaning.
Summary of the invention
It is an object of the invention to provide the phosphate glass of a kind of anti-ultraviolet radiation, this kind of glass not only absorbs heat, and
Ultraviolet permeability is relatively low, is widely used in optical glass and special glass.
The present invention is with phosphate glass as host glass, by adding CeO2, Fe2O3, CuO glass colorant is to reach
To absorbing ultraviolet and the effect of heat absorption.
The each composition by weight percent of glass of the present invention is:
Wherein, the total amount ＜ 12wt%, K of CaO+MgO+BaO2O+Li2O+Na2The total amount ＜ 15wt% of O,
CeO2+Fe2O3The total amount ＜ 5wt% of+CuO.
This kind of glass has the ultraviolet ray transmissivity less than 12%, total solar energy transmitance less than 38% and being higher than
The visible light transmissivity of 75%.
P2O5It it is the composition most important raw material of phosphate glass.Pure P2O5It also is able to melting and forms glass, but it is chemical
It is poor to stablize, it usually needs adds alkali metal oxide and improves the chemical stability of phosphate glass.
Al2O3Improving very important effect of playing the part of in the middle of phosphate glass structure.Al can be with phosphate glass kind
Oxygen with double bond forms aluminum-oxygen tetrahedron, and this structure can effectively improve and strengthen the stability of phosphate glass.
The chemical stability of glass is along with Al2O3Addition gradually step up, work as Al2O3When reaching 15wt%, Al3+To glass web
Stable and the reinforcement of network structure is close to the limit.So, Al2O3Content between 5-20wt%.
Phosphate glass is usually added into K2O、Li2O and Na2O alkaline earth oxide, alkali metal oxide is not only
Can improve the stability of phosphate glass, the most also there is quickening glass melting and high temperature is fluxed to wait and acted on.In the present invention
K2O+Li2O+Na2The total amount ＜ 15wt% of O.
Bivalent metal oxide is added, such as: CaO, MgO and BaO in phosphate glass.Bivalent metal ion
Extra-network ion can be formed, but addition exceedes in certain limit, as network outer body, free oxygen can be brought, make
The network structure of glass becomes loose, and chemical stability is deteriorated, so, the total amount of CaO+MgO+BaO in the present invention
＜ 12wt%.
CeO2It is good ultraviolet absorber, silicate glass is usually added into CeO2Improve its uv absorption
Characteristic, but silicate glass can only absorb a part of CeO2If absorbing excess, glass is by yellowing.And phosphorus
Silicate glass, before variable color, can absorb more CeO2, preventing ultraviolet effect is more preferable.
Total ferrum can not only improve the stability of phosphate glass, Fe simultaneously2O3The ultraviolet absorption ability of glass can be improved,
FeO can improve the heat absorption capacity of glass.But in order to avoid glass seriously colours, incorporation is unsuitable too much, the present invention
Total iron content is between 0.1-1wt%.
