Definitions
- the present invention relates to a dark green glass having a low visible light transmittance, a low ultraviolet transmittance and a low solar transmittance, and suitable for a rear window glass, a sunroof, etc. of a passenger car.
- green glass having high visible light transmittance, low solar radiation transmittance and low ultraviolet transmittance has been used for windshields. It is preferable that the rear window glass and the like also exhibit a green color tone.
- Nickel is not preferred because it sometimes results in the formation of nickel sulfide in the glass. Nickel sulfide can hardly be visually confirmed and does not harm the glass under normal conditions.However, if nickel sulfide is present in the glass after the quenching and tempering treatment, it undergoes crystal transition at room temperature and expands in volume. May generate enough stress to break glass.
- JP-A-2-64038 (corresponding U.S. Pat. No. 4,873,206) No. 759,43 (corresponding European Patent Publication No. 482,533) describes a nickel-free glass having a visible light transmittance of less than 40%.
- Japanese Patent Application Laid-Open No. 2-64038 has a problem that the solar radiation transmittance increases because the ability to block infrared rays is not so large.
- the solar radiation transmittance is low, the iron content is large, so there are significant production problems such as the time required for changing the substrate.
- Japanese Patent Application Laid-Open No. 6-247740 describes a glass in which the Ni0 component is replaced with a chromium component to reduce the visible light transmittance. However, this has a relatively long dominant wavelength and low stimulus purity by adding selenium over 15 PPm and aims to obtain a neutral (gray) color instead of a green color. Further, U.S. Pat.No. 5,411,922 describes a glass having a low visible light transmittance containing iron, cono-poly, and titanium as well as selenium of at least 10 Ppm as an essential component. It has been.
- Se is a volatile and expensive substance at all, and more than 90% of the Se injected into the kiln is mixed with combustion exhaust gas and discharged outside the furnace. It is captured by the absorption liquid in the desulfurization absorption tower. Most of the Se in the solution is recovered and used as a raw material.However, in order to treat the remaining Se ions in the solution after the recovery sufficiently, a lot of capital investment and running is required. Cost is required. In Japan, regulations on the concentration of Se in industrial wastewater will be enforced from 1997.
- Examples 11 to 13 of U.S. Pat.No. 5,411,922 describe the effect of titanium addition on specific glasses containing iron, cobalt, and selenium as essential components. . According to this, as the content of titanium is increased from 0 to 0.63% by weight, the dominant wavelength is changed from 484.6 nm to 541.4 nm, and the excitation purity is 9.3. % To 1.8%, making it easier to obtain neutral (gray) colors.
- European Patent Publication No. 653388 discloses a gray glass to which Ni 0 and Z of 50 ppm or more or Se or 9 ppm or more are added.
- the object of the present invention is to solve the above-mentioned problems of the prior art, to contain only a small amount or no Se, and to reduce the visible light transmittance and the solar transmittance, the total iron content and the chromium content are reduced.
- the goal is to obtain a glass that exhibits a low green color.
- it is intended to obtain a glass which is easy to melt, is manufactured by a normal float glass manufacturing method, and exhibits a deep green color with significantly reduced ultraviolet transmittance.
- the present invention is relative to the base component 1 00 parts by weight of a soda lime glass, as a coloring component, total iron in terms of F e 2 0 3:. 0.
- the glass of the present invention typically has a visible light transmittance ( A light source) is 55% or less and the solar transmittance is 50% or less. When the thickness is 5 mm, the transmittance of light having a wavelength of 370 nm is 25% or less.
- BEST MODE FOR CARRYING OUT THE INVENTION The glass of the present invention is obtained by adding a predetermined amount of a coloring component to 100 parts by weight of a base component composed of soda-lime glass. This coloring component is described below.
- F e 2 0 3 becomes too large visible light transmittance and the content of total iron as calculated is less than 5 parts by weight 0.5, when 2 more than 0 parts by weight, heat is radiant heat of the flame is shut off at the time of melting It is difficult to reach the inside of the molten glass, making it difficult to melt. In addition, the specific gravity of the molten glass increases, and it takes a long time to change the base material, which poses significant production problems.
- the total iron is 1 5-50% of the total iron content of bivalent iron as calculated as F e 2 0 3 is converted to the F e 2 0 3.
- the solar radiation transmittance becomes too large. If it is more than 50%, the radiant heat of the flame is interrupted during melting, making it difficult for the heat to reach the inside of the molten glass, making it difficult to melt.
- the formation of ferric sulfide facilitates the generation of amber color.
- a preferable content of total iron is from 0.5 to 1.5 parts by weight with respect to the base component 1 00 parts by weight
- the content of the preferred F e 0 is the mother component 100 wt It is 0.15 to 0.40 parts by weight, especially 0.20 to 0.40 parts by weight based on parts.
- Titanium together with the cobalt and iron contained as coloring components, colors the glass dark green.
- the invention by the addition of T i 0 2 in excess of 1.0 parts by weight relative to the base component 1 00 parts by weight, may reduce the need amount of S e.
- green can be developed without including Se.
- Titanium is a component that simultaneously absorbs ultraviolet light. In particular, it plays an important role in reducing the transmittance of light with a wavelength of 370 nm.
- All titanium in terms of T i 0 2 is 1.0 parts by weight or less relative to the base component 1 00 parts by weight If it is below, it becomes difficult to obtain dark green glass as the transmittance of light with a wavelength of 370 nm increases, and if it exceeds 3.0 parts by weight, reaction with molten tin in a float bath Cannot be ignored.
- the total titanium is at least 1.1 parts by weight based on 100 parts by weight of the mother component.
- the glass of the present invention but not necessarily, the total cerium vanadium 0.5 parts by weight up to a total of vanadium in terms of V 2 0 5, but not necessarily, obtained by converting the cerium C e 0 2
- the transmittance of light with a wavelength of 370 nm can be further reduced.
- Cobalt is an essential component added to obtain low visible light transmittance. If the content of Co 0 is less than 0.003 parts by weight with respect to 100 parts by weight of the base component, the visible light transmittance becomes too large, and if it exceeds 0.02 parts by weight, the color tone of the glass becomes bluish.
- the addition of Se is not essential, but may be added to adjust the light transmittance in the visible and ultraviolet regions.
- the content exceeds 0.0008 parts by weight with respect to 100 parts by weight of the mother component, the main wavelength becomes long.
- the addition amount is smaller. In that sense, it is preferably substantially not contained. That is, it is preferable not to exceed the amount inevitably mixed as an impurity.
- the stimulus purity of the glass can be reduced to match that, and the color can be adjusted slightly closer to gray.
- Se is added in an amount of 0.0002 parts by weight or more, preferably 0.0003 parts by weight or more, based on 100 parts by weight of the mother component.
- the change in the stimulus purity due to the addition of Se is steep, and when the amount of Se added is large, the stimulus purity increases, and conversely, a dark green color cannot be obtained. There is.
- the Fe 0 amount is set to 0.28 parts by weight or more, particularly 0.30 parts by weight or more based on 100 parts by weight of the base component.
- the amount of Se added is 0.0008 parts by weight or less, preferably 0.0006 parts by weight or less based on 100 parts by weight of the mother component.
- the addition of chromium is not essential, even if it is added especially to reduce the solar transmittance, Good.
- the total chromium converted to C r 2 0 3 is more than 0.05 parts by weight with respect to the base component 1 0 Q part by weight, there is a possibility of foreign matter caused by the generation of Kuromai bets. In order to reduce such a risk, it is preferable that the amount of addition be smaller.
- Nickel (NiO) is preferably not substantially contained in the present invention. Since the rear window glass and sunroof of an automobile, which is the main use of the present invention, are usually reinforced, if nickel is contained in the glass, there is a possibility that the glass may be naturally destroyed. Therefore, do not exceed the amount that is inevitably mixed as an impurity.
- substantially none of Se, chromium, and nickel is contained.
- nickel is not substantially contained, but 0.002 to 0.0008 parts by weight of Se is contained with respect to 100 parts by weight of the mother component. It becomes a glass exhibiting a reddish color.
