[0002] The present application relates to the field of float glass, and in particular to provide solar dark green glass with lower infrared and ultraviolet transmittance. [Background technology]

[0003] Glass products are widely used in the fields of architecture, automobiles, daily use, medical care, chemicals, interior design, electronics, instruments, etc. With the advancement of production technology, the requirements for the performance and gloss of glass products are improved and met, and glasses of different colors are being applied to many automobiles with medium and high-end special performance.

[0004] Although the green glass used in conventional automobiles can achieve the purpose of reducing infrared and ultraviolet ray transmission to a certain extent, it is usually relatively thick, for example, thicker than 2.1 mm, and cannot meet the requirement of having lower infrared and ultraviolet ray transmittance after being thinned due to the need for lightweight automobiles. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions.

[0011] Furthermore, the solar deep green glass has a solar radiation transmittance of 50% or less and an infrared transmittance of 30% or less.

[0012] In addition, the visible light transmittance of solar deep green glass is over 70%.

[0013] Furthermore, the redox ratio of the solar deep green glass is 0.1 to 0.5.

[0014] Furthermore, when the content of TiO2 is 0.2% or more, the ratio of the content of TiO2 to the content of cerium oxide CeO2 is 20 or more.

[0015] Furthermore, when the content of TiO2 is 0.2% or more, the ratio of the content of TiO2 to the content of cerium oxide CeO2 is 20-28.

[0016] Furthermore, when the TiO2 content is less than 0.1%, the ratio of the CeO2 content to the TiO2 content is 5-40.

[0017] Furthermore, the ratio of the CuO content to the Cr2O3 content is 5-60.

[0018] Furthermore, the ratio of the BaO content to the SrO content is 5-40.

[0019] Furthermore, the ratio of the BaO content to the ZrO2 content is 2-8.

[0026] In order to more clearly describe the technical solutions in the embodiments of the present application, the following briefly introduces the drawings required for the embodiments of the present application. [Figure 1] FIG. 1 is a schematic diagram showing a vehicle according to an embodiment of the present application. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] In order to explain the technical contents, objectives and effects achieved by the present invention in detail, the present invention will be described below in conjunction with embodiments.

[0028] An "example" or "embodiment" referred to in this specification means that a particular feature, structure, or characteristic described in connection with the example or embodiment may be included in at least one example of the present application. The appearance of such words anywhere in the specification does not necessarily refer to the same example, nor is it an independent example or candidate example mutually exclusive with other examples. Those skilled in the art can understand, explicitly or implicitly, that the examples described herein can be combined with other examples.

[0029] The present invention provides a solar deep green glass comprising a glass base component and a glass coloring component.

[0030] The glass base components contain, by weight percentage, 63% to 73% SiO2, 10% to 18% Na2O, 4% to 14% CaO, 2% to 6% MgO, 0.1% to 2% A12O3, and 0.01% to 1% K2O.

[0031] The weight percentage of Na2O may be, but is not limited to, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%. In glass, Na2O can reduce the high-temperature viscosity of glass, reduce the structural change threshold of coloring components, and increase the thermal expansion coefficient of glass. If the content is too low, it will reduce the melting ability of glass raw materials, and if the content is too high, it will reduce the weather resistance of glass.

[0032] The weight percentage of K2O may be, but is not limited to, 0.01%, 0.05%, 0.1%, 0.15%, 0.2%, 0.25%, 0.3%, 0.35%, 0.4%, 0.45%, 0.5%, 0.55%, 0.6%, 0.65%, 0.7%, 0.75%, 0.8%, 0.85%, 0.9%, 0.95%, 1%. K2O and Na2O belong to alkali metal oxides, and the role of K2O is similar to that of Na2O. If the total content of Na2O and K2O is too low, it may reduce the melting ability of the glass raw material, and if the total content of Na2O and K2O is too high, it will reduce the chemical stability of the glass, reduce the weather resistance, and increase the production cost.

[0033] The weight percentage of CaO may be, but is not limited to, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%. CaO can improve the stability and devitrification resistance of glass and reduce the high-temperature viscosity of glass. If the CaO content is too high, the glass may devitrify and become less stable, and if the CaO content is too low, it may reduce the melting ability of the glass raw material.

[0034] The weight percentage of MgO may be, but is not limited to, 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, 5%, 5.5%, 6%. MgO can improve the chemical stability of glass and improve the melting ability of glass raw materials. If the content of MgO is too high, it can reduce the devitrification resistance of glass, and the glass can be devitrified and less stable, and if the content of MgO is too low, it can reduce the melting ability of glass raw materials.

[0035] The weight percentage of Al2O3 may be, but is not limited to, 0.1%, 0.3%, 0.5%, 0.7%, 0.9%, 1.1%, 1.3%, 1.5%, 1.7%, 1.9%, 2%. Al2O3 can improve the chemical stability of glass in glass. If the content of Al2O3 is too low, it will reduce the weather resistance of glass, and if the content of Al2O3 is too high, it will result in the glass raw material being difficult to melt.

[0036] SiO2 is the main component of glass, and has relatively stable chemical properties, so that glass has good weather resistance. In the present invention, the weight percentage of SiO2 can be, but is not limited to, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%. If the content of SiO2 in the present application is too low, it will reduce the weather resistance of glass, and as a result, the glass raw material will be difficult to melt.

[0037] The glass coloring components include, by weight percentage, 0.8% to 2.0% total iron (expressed as Fe2O3), 0.01% to 0.6% TiO2, 0.001% to 2.0% CeO2, 5 ppm to 150 ppm Cr2O3, 15 ppm to 60 ppm ZrO2, 2 ppm to 1000 ppm CuO, 5 ppm to 50 ppm SrO, 80 ppm to 200 ppm BaO, and 5 ppm to 120 ppm Co2O3.

[0038] The weight percentage of total iron (represented by Fe2O3) may be, but is not limited to, 0.8%, 0.9%, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2.0%. Total iron (represented by Fe2O3) is used as a primary colorant to color glass green and to adjust the transmittance, and divalent iron (Fe 2+ ) and ferric iron (Fe 3+ ) and other forms. 2+ ) can be considered an infrared absorbing component, and iron(III) (Fe 3+ ) can be an ultraviolet absorbing component. If the total iron (represented by Fe2O3) content is too low, it will reduce the infrared absorbing performance and the ultraviolet absorbing performance. If the total iron (represented by Fe2O3) content is too high, it will lead to a decrease in the visible light transmittance of the glass. The total iron (represented by Fe2O3) according to the present invention represents all iron oxides present in the glass, including both divalent iron (e.g., FeO) and trivalent iron (e.g., Fe2O3). This is a general indication method in this field, and does not mean that all the iron oxides in the glass are iron oxide (III) Fe2O3.

[0039] In the present invention, the ratio of the weight content of divalent iron represented by FeO to the weight content of total iron represented by Fe2O3 is defined as the redox ratio, and is used to adjust the ultraviolet transmittance and infrared transmittance. The redox ratio of the solar deep green glass is 0.1 to 0.5, specifically, 0.17, 0.19, 0.23, 0.24, 0.25, 0.31, 0.37, 0.46, 0.49, etc. can be mentioned. If the redox ratio is too low, it indicates that the content of divalent iron in the glass is too low, and as a result, the infrared absorption ability of the glass is weakened. If the redox ratio is too high, it indicates that the content of divalent iron in the glass is too high, and as a result, the glass raw material is difficult to melt, and the glass has a bluish tinge.

[0040] The weight percentage of titanium dioxide TiO2 may be, but is not limited to, 0.01%, 0.05%, 0.1%, 0.15%, 0.2%, 0.25%, 0.3%, 0.35%, 0.4%, 0.45%, 0.5%, 0.55%, 0.6%. Titanium dioxide TiO2 enables the glass to have the ability to block ultraviolet rays and can also be a yellow colorant. Optionally, the total content of total iron (represented by Fe2O3) and TiO2 is 1.0-2.0%, and the total content of total iron (represented by Fe2O3) and TiO2 may be, but is not limited to, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2.0%. If the total content of total iron (expressed as Fe2O3) and TiO2 is too low, the beneficial effect on the glass becomes less obvious, and if the total content of total iron (expressed as Fe2O3) and TiO2 is too high, it reduces the devitrification resistance of the glass.

[0041] The weight percentage of cerium oxide CeO2 may be, but is not limited to, 0.001%, 0.005%, 0.01%, 0.015%, 0.02%, 0.03%, 0.04%, 0.05%, 0.06%, 0.1%, 0.15%, 0.2%, 0.25%, 0.3%, 0.35%, 0.4%, 0.45%, 0.5%, 1.0%, 1.5%, 2.0%. Cerium oxide CeO2 enables the glass to have the ability to block ultraviolet rays, and can also be used as a yellow colorant. If the content of CeO2 is too low, the beneficial effect on the glass will not be obvious, and if the content of CeO2 is too high, it will greatly increase the production cost of the glass, reduce the production efficiency, and make the glass yellowish. Alternatively, the total content of titanium oxide TiO2 and cerium oxide CeO2 is 0.2% to 2.1%. In the present application, the total content of titanium oxide TiO2 and cerium oxide CeO2 may be, but is not limited to, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, and 2.0%. If the total content of titanium oxide TiO2 and cerium oxide CeO2 is too high, it will reduce the devitrification resistance of the glass, and if the total content of titanium oxide TiO2 and cerium oxide CeO2 is too low, the beneficial effect on the glass will not be obvious.

[0042] Alternatively, when the titanium oxide TiO2 content is 0.2% or more, from the viewpoints of convenience of production and economy, the ratio of the titanium oxide TiO2 content to the cerium oxide CeO2 content is 20 or more, for example, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 40, etc., and more preferably 20 to 28. When the titanium oxide TiO2 content is 0.2% or more, the titanium oxide TiO2 content is greater than the cerium oxide CeO2 content. In this case, if the ratio of the titanium oxide TiO2 content to the cerium oxide CeO2 content is less than 20, the ultraviolet ray blocking performance of the glass is reduced.

[0043] Alternatively, when the content of titanium oxide TiO2 is less than 0.1%, the ratio of the content of cerium oxide CeO2 to the content of titanium oxide TiO2 is 5 to 40, for example, 5, 6, 7, 8, 10, 15, 20, 25, 30, 35, 40, etc., from the viewpoint of convenience of production and economic efficiency. When the content of titanium oxide TiO2 is less than 0.1%, the content of titanium oxide TiO2 is smaller than the content of cerium oxide CeO2. In this case, when the ratio of the content of cerium oxide CeO2 to the content of titanium oxide TiO2 is less than 5, the ultraviolet ray blocking performance of the glass cannot meet the design requirements, and when the ratio of the content of cerium oxide CeO2 to the content of titanium oxide TiO2 exceeds 40, the glass is easily devitrified and is easily turned into ceramics.

[0044] The weight percentage of chromium oxide Cr2O3 may be, but is not limited to, 5 ppm, 10 ppm, 20 ppm, 30 ppm, 40 ppm, 50 ppm, 60 ppm, 70 ppm, 80 ppm, 90 ppm, 100 ppm, 110 ppm, 120 ppm, 130 ppm, 140 ppm, 150 ppm. Chromium oxide Cr2O3 allows the glass to have the ability to block ultraviolet rays and can be a yellow-green colorant, an emerald colorant.

[0045] The weight percentage of copper oxide CuO may be, but is not limited to, 2 ppm, 10 ppm, 20 ppm, 30 ppm, 40 ppm, 50 ppm, 60 ppm, 70 ppm, 80 ppm, 90 ppm, 100 ppm, 200 ppm, 300 ppm, 400 ppm, 500 ppm, 600 ppm, 700 ppm, 800 ppm, 900 ppm, 1000 ppm. Copper oxide CuO can be a blue-green colorant. Optionally, the content of CuO in copper oxide is 100 ppm to 800 ppm. Considering the convenience of production and economic efficiency, the ratio of the copper oxide CuO content to the chromium oxide Cr2O3 content is selectably 5 to 60, for example, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, etc.

[0046] The weight percentage of cobalt oxide Co2O3 may be, but is not limited to, 5ppm, 10ppm, 20ppm, 30ppm, 40ppm, 50ppm, 60ppm, 70ppm, 80ppm, 90ppm, 100ppm, 110ppm, 120ppm. Cobalt oxide Co2O3 is used as a light blue colorant for glass, and can be used to adjust the color of glass, and it also has a certain degree of infrared absorption function. If the content of Co2O3 is too low, the beneficial effect on glass will not be obvious, and if the content of Co2O3 is too high, the result will be weak devitrification resistance of glass. Optionally, the content of cobalt oxide Co2O3 is 8ppm-110ppm.

[0047] The weight percentage of zirconium oxide ZrO2 may be, but is not limited to, 15 ppm, 20 ppm, 25 ppm, 30 ppm, 35 ppm, 40 ppm, 45 ppm, 50 ppm, 55 ppm, 60 ppm. The weight percentage of barium oxide BaO may be, but is not limited to, 80 ppm, 90 ppm, 100 ppm, 110 ppm, 120 ppm, 130 ppm, 140 ppm, 150 ppm, 160 ppm, 170 ppm, 180 ppm, 190 ppm, 200 ppm. The weight percentage of strontium oxide SrO may be, but is not limited to, 5 ppm, 10 ppm, 15 ppm, 20 ppm, 25 ppm, 30 ppm, 35 ppm, 40 ppm, 45 ppm, 50 ppm. Appropriate amounts of zirconium oxide ZrO2, barium oxide BaO, and strontium oxide SrO can improve the chemical stability of glass and improve the hardness of glass. If the content of zirconium oxide ZrO2, barium oxide BaO, and strontium oxide SrO used is too high, the ability of fixing the coloring components of the glass is reduced. If the content of zirconium oxide ZrO2, barium oxide BaO, and strontium oxide SrO used is too low, the beneficial effect on the glass becomes unclear. Considering the convenience and economical aspects of production, the ratio of the content of barium oxide BaO to the content of strontium oxide SrO is preferably 5 to 40, and examples thereof include 5.4, 6, 7, 8, 8.2, 8.3, 8.7, 9, 9.1, 9.6, 9.9, 10, 11, 12, 13, and 14.9. Alternatively, the ratio of the content of barium oxide BaO to the content of zirconium oxide ZrO2 is between 2 and 8, such as 2, 2.9, 3, 3.4, 3.5, 3.8, 3.9, 4.0, 4.2, 5, 6, 7, 8. Alternatively, the content of zirconium oxide ZrO2 is between 30 ppm and 40 ppm.

[0048] Considering the convenience of production and the economical point of view, the solar deep green glass of the present invention does not contain nickel oxide NiO. Nickel oxide NiO usually reduces the visible light transmittance of the glass, but does not reduce the infrared transmittance and the ultraviolet transmittance, and is prone to browning the glass, and reacts with molten tin in the float bath, so that the desired color tone of the glass may not be obtained.

[0049] In the present invention, the ratio of glass coloring components is strictly controlled to obtain solar deep green glass having a thickness of 1.6 mm to 2.1 mm. The thickness of the solar deep green glass may be, but is not limited to, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, or 2.1 mm. The solar deep green glass has a solar transmittance of 65% or less, an infrared transmittance of 45% or less, and an ultraviolet transmittance of 35% or less. In some embodiments, the solar deep green glass has a solar transmittance of 50% or less, and an infrared transmittance of 30% or less. The solar transmittance may be, but is not limited to, 41%, 43%, 45%, 47%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, or 65%. The infrared transmittance may be, but is not limited to, 21%, 23%, 25%, 27%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%. The ultraviolet transmittance may be, but is not limited to, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%. In some embodiments, the visible light transmittance of the solar deep green glass is 70% or more. The visible light transmittance may be, but is not limited to, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%. The present invention can reduce the thickness of glass and reduce the solar transmittance, infrared transmittance, and ultraviolet transmittance of glass.

[0050] As shown in Fig. 1, the present invention further provides a vehicle 100. The vehicle 100 includes a vehicle body 110 and a vehicle window 120. The vehicle window 120 is installed in the vehicle body 110 and includes a solar vitreous glass 121 according to an embodiment of the present invention.

[0051] By mounting the solar deep green glass 121 of the present invention on the vehicle 100 of the present invention, the glass can be made thinner, meeting the needs for weight reduction of automobiles, and the car window 120 can also meet the requirements for lower infrared transmittance and ultraviolet transmittance. In the application of the glass of the car window 120, the solar deep green glass 121 of the present invention can be used as the side glass, rear glass, panoramic sunroof, etc. of an automobile, thereby achieving the purpose of protecting privacy in the interior space of the car, reducing the incidence of infrared and ultraviolet rays, etc., and making the interior of the car more comfortable. The vehicle 100 of the present invention may be, but is not limited to, a passenger car, a multi-purpose vehicle (MPV), a sport / suburban utility vehicle (SUV), an off-road vehicle (ORV), a pickup truck, a wagon, a bus, a truck, etc.

[0052] In the present application, the solar deep green glass may be used as a monolithic glass, or may be manufactured into laminated glass, hollow glass, or vacuum glass. EXAMPLES

[0053] In the present invention, glass raw materials are prepared by mixing basic component raw materials such as silica sand, soda, dolomite, and limestone, coloring component raw materials such as iron powder and titanium oxide powder, a reducing agent, a clarifier, and the like. The glass raw materials are transported into a melting furnace. The melting furnace is heated to 1400°C to 1600°C (for example, about 1500°C) to melt the glass raw materials to obtain a molten glass liquid, which is formed into a glass plate having a predetermined thickness by a glass plate forming method such as the float method. The glass plate is annealed and cooled, and then cut to obtain the glass plates of Examples 1 to 11, and the components are analyzed. The component analysis results of each Example are shown in Tables 1 and 2. [Table 1] [Table 2]

[0054] The glass plates of Examples 1 to 11 were tested in the following manner, and the results are recorded in Table 3.

[0055] In the present invention, using the A standard illumination of the International Commission on Illumination (CIE), the visible light transmittance (Lta) is measured at 10 nm intervals in the range of 380 to 780 nm, the ultraviolet light transmittance (Tuv) is measured at 5 nm intervals in the wavelength range of 300 to 380 nm, and the infrared light transmittance (Tnir) is measured at 50 nm intervals in the range of 780 to 2500 nm. The total solar transmittance (Te) is a calculated value. This calculated value is calculated based on the light transmittance values ​​measured at 50 nm intervals in the wavelength range of 300 to 2500 nm, and Lta, Tuv, Tnir and Te are calculated based on the ISO 9050 standard, and the color index L * , a * , b * is calculated according to the 1976 CIE D65 illuminant standard. [Table 3]

[0057] As can be seen from the above table, the color characteristics of solar dark green glass are as follows. Calculated according to the 1976 CIE standard illuminant D65, L * The range is between 87.51 and 92.82, and * The range of b is between -9.62 and -3.93. * The range is between 0 and 3.19, and L * 、a * and b * is the color index of solar dark green glass. CIE LAB color space (L * a * b * According to the color space defined by the CIE in 1976, color can be expressed by three values: * represents the perceived lightness, and a * represents red and green, two distinct colors in human vision, and b * represents two distinct colors in human vision: blue and yellow. Specifically, L * represents the brightness from black to white, corresponding to 0 to 100, and a * and b * represents a chromaticity without any specific numerical limit. * corresponds to green, and positive a * corresponds to red, and negative b * corresponds to blue, positive b * corresponds to yellow.

[0058] The above is merely an embodiment of the present invention, and does not limit the technical scope of the present invention.
