Description

Our Ref.: AA-778 (F95-4) GLASS HAVING LOW SOLAR RADIATION AND ULTRAVIOLET RAY
TRANSMITTANCE
The present invention relates to glass having low transmittance of solar radiation and ultraviolet ray.
As glass for vehicles having reduced solar radiation transmittance (see JIS 83106) and ultraviolet ray transmittance (see ISO 9050), US Patent 4,792,536 discloses soda lime-silica type glass wherein the weight of Fe0 calculated as Fe203 is made at least 45~ of the weight of the total iron calculated as Fe203. This glass has a bluish color.
With this glass, Glauber's salt used as a refining agent does not provide a refining function, since the weight of Fe0 calculated as Fe203 is at least 45$ of the weight of the total iron calculated as Fe203.
Accordingly, molten glass is required to be maintained under reduced pressure for fining, which makes the melting step of glass cumbersome.
Further, soda lime-silica type glass containing at least 0.51 wt$ of Fe203, is known. This glass has a I
greenish color.
As such glass, for example. the following glass is disclosed in US Patent 5,077,133. Namely, it has a thickness of 3 mm and contains from 0.68 to 0.92 wt% of total iron, from 0.5 to 1.2 wt% of Ce02 and from 0.02 to 0.85 wt% of Ti02, wherein the amount of bivalent iron in the total iron is from 23 to 29 wt%. Another one has a thickness of 4 mm and contains from 0.61 to 0.86 wt% of total iron, from 0.3 to 0.75 wt% of.Ce02 and from 0.02 to 0~45 wt% of Ti02, wherein the amount of bivalent iron in Japanese Unexamined Patent Publication No. 6-56466 (i.e., 56466/1994, Asahi Glass Company, Ltd., published March 1, 1994) discloses glass having low solar radiation and ultraviolet ray transmittance, which consists essentially of a soda lime-silica type matrix glass containing from 0.53 to 0.70 wt% of total iron calculated as Fe203, from 0.2 to 0.4 wt% of Ti02 and from 0.4 to 0.8 wt% of total cerium calculated as Ce02, wherein the weight of Fe0 calculated as Fe203 is from 30 to 40% of the weight of the total iron calculated as Fe203.
In recent years, there has been an increasing demand for glass having the ultraviolet ray absorption further improved, particularly for automotive use. The present invention is to satisfy such a demand.
It is an object of the present invention to provide glass having a visible light transmittance of at least 70% and low solar radiation transmittance and having 21613~~
substantially reduced ultraviolet ray transmittance, particularly transmittance at a wavelength of 370 nm.
The present invention provides glass having low solar radiation and ultraviolet ray transmittance, which consists essentially of a soda lime-silica type glass containing from 0.52 to 0.67 wt$ of total iron calculated as Fe203, from 0.2 to 0.6 wt~ of Ti02 and from 0.9 to 2.0 wt~ of total cerium calculated as Ce02, wherein the weight of Fe0 calculated as Fe203 is from 28 to 38~ of the weight of the total iron calculated as Fe203.
If the content of the total iron calculated as Fe203 is small, the solar radiation transmittance and the ultraviolet ray transmittance tend to be too high, and if it is large, the visible light transmittance tends to be too small. The content of the total iron is preferably at most 0.64 wt$, more preferably at most 0.63 wt$. If the amount of bivalent iron in this total iron is small, the solar radiation transmittance tends to be too high, and if it is large, the melting step of glass tends to be cumbersome, and the glass tends to have a bluish color.
If the Ce02 content is too large, the costs for the raw material will be high, and it will require a long time to change the composition at the time of producing glass, whereby the productivity will be low. Further, the glass tends to have a yellowish color.
If the Ti02 content is too small, the ultraviolet ray transmittance tends to be too high, and if it is large, the visible light transmittance tends to be too small, and the glass tends to have a yellowish color.
To keep the ultraviolet ray transmittance at a low level, in the second embodiment of the present invention, Ce02 + Ti02 is preferably from 1.2 to 2.3 wt~.
Co0 is not an essential component. However, by incorporating it in a very small amount, the color of glass which tends to be yellowish by Ce02 and Ti02, can be adjusted to a green color. It is preferably contained in an amount of at least 0.0002 wt~.
If its content is too large, the visible light transmittance will be too small.
Among various components, the contents of the total iron and Ce02 are preferably adjusted as follows depending upon the thickness of the glass. Namely, when the thickness is from 1.7 to 4.3 mm, the content of the total iron calculated as Fe203 is preferably from 0.59 to 0.64 wt~, and at the same time, the content of Ce02 is preferably from 1.2 to 2.0 wt~. Further, when the thickness is from 1.7 to 4.4 mm, the content of the total iron calculated as Fe203 is particularly from 0.60 to 0.64 wt~, the content of Ti02 is particularly from 0.3 to 0.5 wt$, the content of the total cerium calculated as Ce02 is particularly from 1.4 to 1.7 wt~, and the weight of Fe0 calculated as Fe203 is from 30 to 35~ of the weight of the total iron calculated as Fe203. Likewise, when the thickness is from 4.4 to 5.5 mm, the content of the total iron calculated as Fe203 is preferably from 0.52 to 0.63 wt~, and at the same time, the content of Ce02 is preferably from 0.9 to 1.2 wt$. Further, when the thickness is from 4.4 to 7.0 mm, the content of the total iron calculated as Fe203 is particularly from 0.57 to 0.62 wt~, the content of Ti02 is particularly from 0.2 to 0.4 wt~, the content of the total cerium calculated as Ce02 is particularly from 0.9 to 1.4 wt~, and the weight of Fe0 calculated as Fe203 is from 30 to 35~ of the weight of the total iron calculated as Fez03.
The soda lime-silica type glass can be commonly used for vehicles or architectural use. Thus, one of preferred glass compositions of the present invention is as follows:
Si02 68 - 74 wtg A1203 0.5 - 3 wt~
Mg0 , 3 - 6 wtg Ca0 6 - 10 wt~
Na20 + K20 10 - 16 wt~
So3 0.05 - 1 wt~
Total iron calculated as Fe203 0.52 - 0.67 wt~
Fe203 0.35 - 0.50 wt~
Fe0 0.16 - 0.24 wt~
Ti02 0.2 - 0.6 wt~
Total cerium calculated as Ce02 0.9 - 2 wt~
If the Si02 content is small, the weathering resistance tends to be low, and if it is large, devitrification is likely to result. If the A1203 content is small, the water resistance tends to be low, and if it is large, the meltability tends to be low.
Na20 and K20 are components which serve to promote melting of raw materials. If their total amount is small, such an effect tends to be small, and if it is large, the weathering resistance tends to be poor.
Ca0 and Mg0 are components which serve to promote meltability of the raw materials and improve the weathering resistance. If their content is small, such effects tend to be small, and if it is large, devitrification is likely to occur.
If the content of the S03 is small, the refining effect tends to be low.
Also in the present invention, the specific gravity of the glass is adjusted preferably to a level of from 2.49 to 2.53, more preferably from 2.51 to 2.52, in conformity with usual soda lime-silica type glass, with a view to improving the efficiency for the change of the composition.
The specific gravity can be adjusted in the same manner as in the first embodiment by controlling the composition of the matrix glass. Specifically, the weight ratio of Si02/(Mg0 + CaO) is adjusted to a level of from 5.0 to 7.0, preferably from 5.4 to 6.6, more preferably from 6.0 to 6.6. most preferably from 6.2 to 6.6.

~~~~J~~
_ 7 _ The glass of the present invention has a dominant wavelength of from 500 to 540 nm, particularly from 515 to 535 nm, for transmittance, and is usually employed in a thickness of from 1.7 to 7 mm. It is characterized by a solar radiation transmittance of from 45 to 52~, a visible light transmittance (by light source A) of at least 70$, an ultraviolet ray transmittance of not higher than 15~, particularly not higher than 10~, a transmittance of light having a wavelength of 370 nm of not higher than 30$, and an excitation purity of from 2 to 3~.
The glass of the present invention having low solar radiation and ultraviolet ray transmittance can be used as single sheet glass, laminated glass or double glazing unit panes. In the case of laminated glass or double glazing unit, glass sheets of the present invention may be used for the,both sides of the laminated glass or the double glazing unit. Otherwise, the glass of the present invention may be used in combination with other kinds of glass to form the laminated glass or the double glazing unit.
The glass of the present invention having low solar radiation and ultraviolet ray transmittance can be prepared, for example, as follows. Namely, various raw materials are mixed so that the desired glass composition would be obtained. With respect to the raw materials useful for this purpose, iron powder or red iron oxide _8_ may, for example, be used as the Fe0 and Fe203 source;
cerium oxide, cerium carbonate or cerium hydroxide may, for example, be used as the cerium source; and titanium oxide may, for example, be used as the titanium source.
As the raw materials for the matrix glass, those commonly used may be employed. Further, it is preferred to add a reducing agent such as carbon to these raw materials, so that iron in the molten glass is prevented from being oxidized to Fe203, and Fe0 will be contained in a predetermined amount.
The glass batch thus adjusted is continuously supplied to a melting furnace, and heated and melted at a temperature of about 1,500°C by e.g. heavy oil for vitrification. Then, this molten glass is refined and formed into a sheet glass having a predetermined thickness by e.g. a float process. Then, this sheet glass is cut into a predetermined shape to obtain the glass of the present invention having low solar radiation and ultraviolet ray transmittance. Further, the cut glass may be subjected to toughening, laminating or composing into double glazing unit.
Now, the present invention will be described in further detail with reference to Examples. However, it should be understood that the present invention is by no means restricted to such specific Examples.
EXAMPLES 1 to 9 Soda lime-silica glass having the total iron ~1~~37~

calculated as Fe203, Ce02, Ti02 and Co0 incorporated in the amounts identified in the upper section of Table 1 as optical property-improving components to a matrix composition comprising 71 parts (parts by weight, the same applies hereinafter) of Si02, 1.7 parts of A1203, 12.3 parts of Na20, 0.5 part of K20, 8 parts of CaO, 3.5 parts of Mg0 and 0.6 part of S03, was prepared. The ratio of bivalent iron (in Table 1, referred simply as FeII) to the total iron was also identified in the same section.
In the preparation of the glass, the preliminarily formulated glass batch was put into a platinum pot of 300 cubic centimeters, and heated and melted in an electric furnace for vitrification. Then, the molten glass was cast on a stainless steel plate, and both sides of the formed sheet were polished to obtain a sheet glass having a thickness of 3.5 mm (5.0 mm in Examples 6, 7 and 9).
With respect to these sheets, the solar radiation transmittance Te, the visible light transmittance (by light source A) Tva, the ultraviolet ray transmittance TUB, the transmittance of wavelength at 370 nm T3~o, the dominant wavelength DW and the excitation purity PE were obtained, and the results are shown in the lower section of Table 1. Also with respect to the glass of Comparative Example (Example 8), such properties were obtained in the same manner, and they are shown also in Table 1.

The solar radiation transmittance and the visible light transmittance were determined by JIS 83106, the ultraviolet ray transmittance was determined by ISO 9050, and the dominant wavelength and the excitation purity were determined by JIS 28722.
As is evident from Table 1, the glass of the present invention has a green color and has high visible light transmittance, low solar radiation transmittance and particularly low ultraviolet ray transmittance.
