Definitions
- the present invention relates to a dark green-gray low-permeable glass composition, and more particularly, using Fe 2 O 3 , CoO, Se and Cr 2 O 3 in a specific content range as a coloring component (CoO + Cr By limiting the relative content of 2 O 3 ) vs Se and CoO vs Cr 2 O 3 to a certain range, it effectively controls visible light transmittance (LT A ) to satisfy the privacy barrier performance, and provides solar transmittance (T e ) and ultraviolet light Lower transmittance (T uv ) reduces cooling loads in vehicles, buildings, etc., protects interior materials and people from UV rays, meets the optimal color coordinate range of transmissive colors, reduces eye strain and provides psychological stability.
- a green gray low permeation glass composition By limiting the relative content of 2 O 3 ) vs Se and CoO vs Cr 2 O 3 to a certain range, it effectively controls visible light transmittance (LT A ) to satisfy the privacy barrier performance, and provides solar transmittance (T e
- the use of the colored glass is not particularly limited, but may be applied to privacy glass or sun roof and architectural glass of automobile safety glass.
- Colored glass has lower visible light transmittance (LT A ) than ordinary soda-lime glass, which reduces the visibility inside the vehicle, and reduces the heat absorption into the vehicle due to its low solar energy transmittance (T e ).
- LT A visible light transmittance
- T e low solar energy transmittance
- T uv due to the low UV transmittance it is possible to prevent damage to the fabric, discoloration or decomposition of the internal materials by ultraviolet light.
- color improvement, UV protection, and solar energy absorption function can be realized by incorporation of various elements, and representative elements include iron (Fe), cobalt (Co), and selenium (Se).
- chromium (Cr), manganese (Mn), titanium (Ti), cerium (Ce), nickel (Ni), copper (Cu), and the like may further be used.
- Each of the elements has a unique coloring effect, and the property of absorbing ultraviolet rays and solar energy, which is due to the phenomenon that each element absorbs a specific wavelength. Therefore, it is possible to design a glass having a desired color and transmittance by the combination of the ratios of the elements added.
- Such low-permeable glass compositions can be broadly divided into the case where Fe, Co, and Se are made of a basic coloring element and the case of adding other elements.
- U.S. Patent No. 4,873,206 discloses a glass composition comprising 0.6-1.0 wt% total Fe 2 O 3 , 0.005-0.02 wt% Se and 0.01-0.02 wt% CoO, and free of Ni and Cr.
- the composition has a privacy barrier function, which is an important function of the low-permeability glass composition applied to the sunroof or rear-view privacy glass with a visible light transmittance (LT A ) of 25 to 30% based on a glass thickness of 4 mm. It is not suitable to impart, and there is also a limit to forming a colored glass composition of dark greenish gray color.
- the present invention is to solve the problems of the prior art as described above, by effectively controlling the visible light transmittance (LT A ) of the glass to satisfy the privacy blocking performance, solar energy transmittance (T e ) and ultraviolet transmittance (T uv Low green light transmission that reduces cooling loads in vehicles and buildings, protects interior materials and people from ultraviolet rays, and satisfies the optimal color coordinate range of transmissive colors to reduce eye fatigue and provide psychological stability. It is a technical problem to provide a glass composition and the glass formed therefrom.
- the dark green gray low-permeability glass composition according to the preferred embodiment of the present invention has a visible light transmittance (LT A ) of 15% or less, a solar energy transmittance (T e ) of 16% or less, and 5% or less based on a glass thickness of 4 mm.
- the dark green-gray low-permeable glass composition according to one preferred embodiment of the present invention has L * of 35 to 50, a * of -5 to 0, and b in a color coordinate (light source D65, 10-degree field of view) of transmission color. * Has a range of 0 to 6.
- the deep green gray low-permeable glass composition of the present invention is excellent in absorbing visible light, solar energy and ultraviolet rays, and thus can effectively perform privacy protection, cooling load reduction, and UV blocking functions in vehicles and buildings. Satisfaction can reduce eye strain and provide psychological stability.
- the mother glass a mother glass composed of components and contents conventionally used in the art may be adopted without particular limitation.
- the mother glass may be used comprising the components and contents (based on a total of 100% by weight of the mother glass) of Table 1 below.
- SiO 2 serves to form a network structure, which is a basic structure of glass, and if the content is less than 65% by weight, problems may occur in the durability of the glass, and if the content exceeds 75% by weight, high temperature viscosity May increase excessively and the meltability may decrease.
- Al 2 O 3 is a component that increases the high temperature viscosity of the glass and improves the durability of the glass when a small amount is added. If the content is less than 0.3% by weight, the chemical resistance and water resistance may be lowered, and the content is more than 3% by weight. The melt load may increase with increasing high temperature viscosity.
- Na 2 O and K 2 O are flux components that promote the melting of glass raw materials. If the combined content of the two components is less than 10% by weight, the melt quality may decrease due to an increase in cosmetic melt, and the sum of the two components If the content exceeds 18% by weight, the chemical resistance may be lowered.
- CaO and MgO help to melt the raw materials and reinforce the weather resistance of the glass structure. If the content of CaO is less than 5% by weight, durability may be degraded. If the content of CaO is more than 15% by weight, it may adversely affect product quality due to an increase in crystallization tendency. In addition, when the content of MgO is less than 1% by weight, the above-described melting aid and weathering reinforcement effects may be insignificant, and when the content of MgO is more than 7% by weight, crystal defects may occur due to an increase in crystallization tendency.
- the mother glass in the actual production of the mother glass can be used additionally (Na 2 SO 4 ) to improve the melt quality, such as bubble removal.
- Na 2 SO 4 Na 2 SO 4
- Iron (Fe) may be included as an impurity in the main and secondary raw materials of glass, and may be present in the glass at a level of 0.1 to 0.2% by weight without additional input in normal commercial production. Most colored glass uses iron oxide (Fe 2 O 3 ) as a raw material to add iron to control the desired transmittance and color. Iron oxide (Fe 2 O 3 ) introduced during the melting of the glass may be present as Fe 3 + and Fe 2+ . Fe 3+ ions have a weak absorption in the visible light region of 410 ⁇ 440nm and a strong absorption edge in the vicinity of the ultraviolet light around 380nm, due to this property, the more Fe 3+ is present, the glass becomes pale yellow.
- Fe 2+ ions are known to absorb infrared rays because there is a strong absorption band around 1050nm, the more the Fe 2+ content, the color of the glass changes to blue.
- the proportion of Fe 2+ and Fe 3+ in the total Fe 2 O 3 is fluid depending on the glass manufacturing process.
- the glass composition of the present invention comprises a total of Fe 2 O 3 1.2 ⁇ 2 parts by weight based on 100 parts by weight of the base glass.
- the total Fe 2 O 3 content may be, for example, 1.2, 1.3, 1.4, 1.5, or 1.6 parts by weight or more, for example, 2, 1.9, 1.8, or 1.7 parts by weight or less.
- the increase in visible light transmittance (LT A ) results in one of the most important performances of the low-permeability glass composition, which is the privacy protection and solar energy blocking. Its function is lowered, and the color purity is increased when it exceeds 2 parts by weight, and the visible light transmittance (LT A ) is extremely reduced, which lowers the visibility, making it unsuitable for use as a window of a vehicle and a building, and increasing the content of Fe 2+ which absorbs radiation infrared rays. May inevitably occur and cause an increase in the melt load, such as lowering of the lower temperature in the melting furnace.
- the total Fe 2 O 3 content is more preferably 1.2 to 1.8 parts by weight, and 1.3 to 1.5 parts by weight based on 100 parts by weight of the mother glass. Even more preferred.
- the FeO content is less than 10% of the total Fe 2 O 3 content, the solar energy transmittance (T e ) increases, and there is a possibility that se coloring is halved because selenium is more likely to exist in the SeO 2 form than the Fe-Se form.
- the FeO content exceeds 30% of the total Fe 2 O 3 content, there is a problem that Se volatility increases, so that an appropriate amount of Se may not remain in the glass, and thermal conductivity in the melting process due to the increase in Fe 2+ may occur.
- the FeO content is more preferably 15-30% of the total Fe 2 O 3 content, and even more preferably 20-30%.
