Line transmitance is 28%, ultraviolet ray transmissivity 18%, sunshine gross energy transmitance TSET >=48%, since iron-holder is too high, glass
Nearly 300 degree of glass liquid upper and lower temperature difference, moulding process is difficult, can not carry out batch production.
United States Patent (USP) (US005362689A) discloses a kind of infrared and ultraviolet radiation absorbing glass, and constituent is：
The SiO of 68-72wt%2, the Al of 1.6-3.0wt%2O3, the MgO of the CaO of 8.5-11.0wt%, 2.0-4.2wt%, 12.0-16.0wt%
Na2The K of O, 0.5-3.0wt%2The SO of O, 0.08-0.30wt%3, total iron (Fe of 0.58-0.80wt%2O3), 0.10-0.60wt%
CeO2, the TiO of 0.10-0.40wt%2With the MnO of 5-350PPM, Fe in glass2+/Fe3+Value is in the range of 0.3-0.7 wt%；
The glass has the visible light transmittance not less than 67%, and infrared light transmission is less than 21%, and total solar energy transmitance is in 30%-
In the range of 47%, ultraviolet ray transmissivity is in the range of 7%-15%, dominant wavelength ranges 505-518nm, and excitation purity is no more than 5.5%.
This kind of glass visible light transmittance is relatively low.
As can be seen from the above patents that in most soda lime glass, by mixing iron powder Fe2O3It is inhaled to reach
Receive the effect of infrared ray；Iron is in glass generally with ferric ion (Fe3+) and ferrous ion iron（Fe2+) two kinds of forms deposit
；Fe2+In near-infrared, near infrared region there are one wider absorption band, can absorb the infrared ray for injuring human eye strongly,
Fe3+Then have the function of to absorb ultraviolet light.By adjust content between the two and containing ratio adjust the color of glass and
Light transmission.
To sum up, existing bulk doped antisolar glass is also difficult to meet simultaneously that intensity is high, visible light transmittance is high and strong
Absorb the requirement of infrared ray.
The content of the invention
It is an object of the invention to overcome above-mentioned difficulties, a kind of energy-saving safety glass of strong absorption near infrared ray is provided.
The present invention adopts the following technical scheme that complete above-mentioned purpose：
A kind of energy-saving safety glass of strong absorption near infrared ray, the energy-saving safety glass use boro-alumino-silicate glass system group
Point, include glass body and colorant；The glass body and the total weight of colorant are 100wt%；The glass body
Raw material forms and weight ratio in glass is：The SiO of 60.0-76.3wt%2, the B of 8.5-12.0wt%2O3、6.8-
The Na of 14.35wt%2O, the Al of 1.0-3.0wt%2O3, 0.25-2.25wt% CaO；The composition of the colorant and in glass
In weight ratio be：The Fe of 0.40-0.60wt%2O3With the SnO of 0.50-1.00wt%2；The wherein described Fe2O3 It is inhaled for infrared ray
Receive agent；The SnO2 For infrared absorbent and reducing agent；The energy-saving safety glass is heated to 1550 DEG C in high temperature furnace
Glass melting temperature after heat preservation 2.5 it is small when after natural cooling form；The energy-saving safety glass has under 6mm thickness to be not less than
73% visible light transmittance, the near infrared ray transmitance less than 30%；The glass thermal expansion softening point of the energy-saving safety glass
For 630 DEG C, the coefficient of expansion is 6.15 × 10-6/ DEG C；The glass surface hardness of the energy-saving safety glass is 605.3HV.
The raw material composition of the glass body and weight ratio in glass are：The SiO of 60.0-76.3wt%2,
The B of 10.0wt%2O3, 10.35wt% Na2O, the Al of 2.2wt%2O3, 1.25wt% CaO；The composition of the colorant and
Weight ratio in glass is：The Fe of 0.52wt%2O3With the SnO of 0.80wt%2；
The raw material composition of the glass body and weight ratio in glass are：The SiO of 60.0-76.3wt%2, 10.0wt%'s
B2O3, 10.35wt% Na2O, the Al of 2.2wt%2O3, 1.25wt% CaO；The composition of the colorant and weight in glass
Measuring ratio is：The Fe of 0.60wt%2O3With the SnO of 1.00wt%2。
The reasons why illustrating to be defined the composition of energy-saving safety glass below, all percentage is weight hundred below
Fraction.
SiO2It is for forming the necessary ingredient of glass skeleton, content more increases, on the one hand, chemical durability is got over
Height, electric property are better.On the other hand, have and put forward full-bodied tendency, so, it is difficult to obtain the glass of material property length if excessive
Glass.
B2O3It is for improving glass structure stability, reducing glass viscosity, reduction surface tension, raising wetability, reduction
The necessary composition of the coefficient of expansion, content more increase, and glass will show low viscosity, but are also present with reduction vitrifying
Learn stable tendency, the use of long-time natural environment will surface there is weathering.
Al2O3It is the neccessary composition for significantly improving chemical durability of glass, reduces devitrification of glass tendency, while it is to carry
The necessary composition of high glass hard (HRC65Yi Shang) and mechanical strength.
Na2O is glass network modifier oxides, can reduce the viscosity of glass, glass is made to be easy to melt, and is that glass is good
Cosolvent, but it can increase the coefficient of thermal expansion of glass simultaneously, and thermal stability, chemical stability and the machinery for reducing glass are strong
Degree so cannot introduce excessively, is usually no more than 18%, introducing is very few, and the fusing effect of glass is with regard to poor.
CaO is glass network modifier oxides, and main function in glass is stabilizer, that is, the chemistry for increasing glass is steady
Qualitative and mechanical strength, but when content is higher, the crystallization of glass is made to be inclined to increase, and easily makes glass embrittlement.
Iron oxide Fe2O3It is a kind of impurity contained in sandstone, its existence form has Fe2+And Fe3+Two kinds, Fe2+It can make
Glass is in dark green, Fe3+Making glass, the colorability of low price iron is about 10 times of high price iron colorability in yellow green.
Either high price iron or low price iron can all reduce the transparency of glass, thus in glass iron-holder increase can reduce transparency and
Glossiness influences the quality of glass.Fe2+And Fe3+There are strong absorption, but Fe to ultraviolet light2+Have to infrared ray strong
Strong absorption, Fe3+To infrared ray substantially without absorption.
Tin oxide SnO2It is white, faint yellow or light gray is cubic, six sides or orthorhombic system powder.1630 DEG C of fusing point, boiling
1800 DEG C of point.There is good permeability to visible ray, in aqueous solution with excellent chemical stability, and with specific
