For ranges of values, between the endpoints of each of the ranges and the individual points, and between the individual points may be combined with each other to give one or more new ranges of values, and these ranges of values should be considered as specifically disclosed herein.
In a first aspect, the present invention provides a composition for glass comprising 55 to 60% by weight, calculated as oxide, of SiO, based on the weight of the composition215-22 wt% of Al2O36-10 wt% of B2O37-12 wt% of Na2O, 0-3 wt% of K2O, 3.5-5.5 wt% of CeO20-2 wt% of TiO20-2 wt% of RO, 0-0.3 wt% of ZnO, 0.001-0.02 wt% of Fe2O3；
Wherein RO is an alkaline earth metal oxide.
In the present invention, the iron content was measured using a thermoelectric iCAP 6300MFC type inductively coupled plasma emission spectrometer (ICP) without specific description.
In some embodiments of the present invention, preferably, RO is selected from at least one of MgO, CaO, SrO, and BaO.
In the composition for glass provided by the invention, SiO2The glass is a glass forming body, if the content is too low, the thermal stability is not enhanced, the expansion coefficient is too high, and the glass is easy to devitrify; increase SiO2The content contributes to weight reduction of the glass, a reduction in thermal expansion coefficient, an increase in strain point, and an increase in chemical resistance, but the high-temperature viscosity increases, which is disadvantageous in melting. Thus, SiO is calculated as the oxide based on the weight of the composition2In an amount of 55 to 60 wt%, e.g., 55 wt%, 56 wt%, 57 wt%, 58 wt%, 59 wt%, 60wt%, and any value in the range of any two numerical compositions, preferably 57 to 59 wt%.
In the composition for glass provided by the invention, Al2O3The addition of the (B) can accelerate the process and depth of ion exchange, is a component beneficial to chemical strengthening, and helps to improve the flexibility of the flexible packaging cover plate. Al (Al)2O3The addition of the glass can promote the integrity of glass network connection, so that the heat resistance stability and the mechanical stability of the glass are greatly improved. Thus, Al2O3The content is more than 15 wt%, preferably more than 16 wt%, and further preferably more than 17 wt%. On the other hand, Al2O3Strong ability to compete for free oxygen, and large amount of introduced Al2O3Can reduce the openness degree of the glass structure, lead the glass to tend to be rigid, increase the brittleness of the glass, simultaneously lead the glass to be easy to devitrify, have overlarge high-temperature surface tension and high-temperature viscosity, increase the difficulty of the glass production process and the like, and simultaneously find Al in the research content range2O3The transmittance of the glass in a visible light area can be obviously reduced and the color of the glass can be deepened when the content is increased. To better make Al2O3Exerting its effect, Al2O3Is less than 22 wt%, preferably less than 21 wt%, and more preferably less than 19 wt%. Thus, Al is calculated as the oxide based on the weight of the composition2O3Is 15 to 22 wt%, for example, 15 wt%, 16 wt%, 17 wt%, 18 wt%, 19 wt%, 20 wt%, 21 wt%, 22 wt%, and any value in the range of any two numerical values, preferably 17 to 19 wt%.
In the composition for glass provided by the present invention, B2O3The addition of B can reduce the brittleness of the glass, improve the fracture toughness and the heat-resistant stability of the glass and simultaneously2O3Is also a good cosolvent, can greatly reduce the melting temperature of the glass, and is also beneficial to the vitrification process. Having [ BO ] in glass4]Tetrahedron and [ BO3]Two structures of triangle, B under high temperature melting condition2O3Difficult to form [ BO4]The viscosity at high temperature can be reduced, and tetrahedron formation is preferentially performed at low temperature depending on the amount of free oxygenOr a triangular body. In alkali aluminosilicate glasses, [ BO4]The tetrahedron may be reacted with [ SiO ]4]Tetrahedra form a unified continuous three-dimensional network, and [ BO3]The triangular bodies are connected by a rotatable boron ring, and slide is generated after stress, so that plastic rheology is caused, and the triangular bodies have lower brittleness and higher fracture toughness. However, too much B2O3The low-temperature viscosity of the glass is reduced, which is not beneficial to the adjustment of the subsequent chemical toughening process. Thus, based on the weight of the composition, calculated as the oxide, B2O3Is 6 to 10 wt%, e.g., 6 wt%, 7 wt%, 8 wt%, 9 wt%, 10 wt%, and any value in the range of any two numerical values, preferably 8 to 9 wt%.
In the composition for glass provided by the present invention, Na+And K+Are ion-exchanged components, and an appropriate increase in the content thereof is effective in lowering the high-temperature viscosity of the glass, thereby improving the meltability and formability and improving devitrification. However, too high a content thereof increases the thermal expansion of the glass and lowers the chemical durability of the glass, and too high a content thereof tends to deteriorate the devitrification property, and in the case of chemical tempering, Na in the glass+K in the melt+Replacement of Na in glass+The toughening effect can be obviously improved by properly increasing the content.
In some embodiments of the present invention, preferably, Na is present as an oxide, based on the weight of the composition2The content of O is 7 to 12% by weight, for example, 7% by weight, 8% by weight, 9% by weight, 10% by weight, 11% by weight, 12% by weight, and any value in the range of any two numerical values, preferably 9 to 11% by weight.
In some embodiments of the invention, it is preferred that K is calculated as the oxide based on the weight of the composition2The content of O is 0 to 3% by weight, for example, 0% by weight, 0.5% by weight, 1% by weight, 1.5% by weight, 2% by weight, 2.5% by weight, 3% by weight, and any value in the range of any two numerical values, preferably 0 to 2% by weight.
In the composition for glass provided by the invention, CeO is introduced2The radiation resistance stability of the glass is improved. Glass under high energy rayUnder irradiation, color centers are generated and generate new absorption bands in a visible light wave band, so that the glass is colored, the transmittance of the glass is reduced, and the service efficiency of the solar cell is influenced. In order to improve the radiation resistance of the glass, a certain amount of a valence-change oxide is usually added to the base glass to prevent the generation of color centers. CeO (CeO)2The effect on improving the radiation resistance of glass can be given by the equation Ce4++e＝Ce3+Is represented by (C) CeO2The local nuclear unbalance generated by electrons and vacancies can be compensated, so that the formation of color centers in the glass is inhibited, the irradiation damage of the glass is reduced, and the irradiation resistance of the glass is effectively improved. Thus, CeO is calculated as the oxide based on the weight of the composition2Is 3.5 to 5.5 wt%, e.g., 3.5 wt%, 4 wt%, 4.5 wt%, 5 wt%, 5.5 wt%, and any value in the range of any two values, preferably 4.5 to 5 wt%.
In the composition for glass provided by the invention, TiO2The irradiation resistance of the glass can be improved, and the high-temperature viscosity and the crystallization upper limit temperature of the glass can be reduced; the product has effects of improving strength and increasing flexibility below softening point, but excessive TiO2The content may cause the density to rise too fast. Thus, TiO is calculated as the oxide based on the weight of the composition2Is 0 to 2 wt%, e.g., 0 wt%, 0.01 wt%, 0.1 wt%, 0.5 wt%, 1 wt%, 1.5 wt%, 2 wt%, and any value in the range of any two values, preferably 0.01 to 1 wt%.
In some embodiments of the invention, it is preferred that RO is present in an amount of 0 to 2 wt%, e.g., 0 wt%, 0.1 wt%, 0.2 wt%, 0.3 wt%, 0.4 wt%, 0.5 wt%, 1 wt%, 1.5 wt%, 2 wt%, and any value in the range of any two values, preferably 0 to 0.5 wt%, more preferably 0 wt%, calculated as oxides, based on the weight of the composition.
In the composition for glass, ZnO can reduce the high-temperature viscosity (such as 1500 ℃) of glass, and is favorable for eliminating bubbles; at the same time, the glass has the functions of improving the strength and the hardness, increasing the chemical resistance of the glass, reducing the thermal expansion coefficient of the glass and improving the irradiation resistance below the softening point. In an aluminosilicate glass system, a proper amount of ZnO is added, which is beneficial to inhibiting crystallization and can reduce crystallization temperature. Too much ZnO content will cause the strain point of the glass to be greatly reduced. Thus, the ZnO content is 0 to 0.3 wt%, e.g., 0 wt%, 0.1 wt%, 0.15 wt%, 0.2 wt%, 0.25 wt%, 0.3 wt%, and any value in the range of any two values, preferably 0.1 to 0.2 wt%, calculated as oxide, based on the weight of the composition.
