Description

具有未回火片材的轻质抗飓风窗和层压件
相关申请的交叉引用
本申请根据35U.S.C.§119，要求2018年11月29日提交的第62/772,727号美国临时申请的优先权权益，其内容通过引用全文纳入本文。
技术领域
本公开一般涉及抗飓风层压窗格件，其具有两片玻璃和聚合物夹层，其中一片玻璃未经过回火，这意味着其未经过热或化学强化，而是基本上处于“生产时”的强度状态，本发明还涉及使用一个或多个这样的层压窗格件的窗，以获得抗冲击和抗压力循环的综合性能，例如在抗飓风窗中，或者用于其他目的，例如用于提高抗侵入性。
背景技术
所谓的抗飓风窗通常采用增强的框架和间隔件组件，以及内层压窗格件(pane)，该内层压窗格件包括两片玻璃和具有高弹性模量(或在足够快的变形下具有高弹性模量)的聚合物夹层。图3(现有技术)示出了这种窗200的示例，该窗旨在用作抗飓风窗(或用于这种窗的IGU 200)。
如图3所示，窗200包括外窗格件10和内层压窗格件12。外窗格件10通常为单个玻璃片材50的形式，该片材50的表面对应于窗200的外表面或第一表面S1和第二表面S2(内部)。层压窗格件12包括第一片20的玻璃和第二片70的玻璃，并且在第一片20和第二片70之间粘附有聚合物夹层40。聚合物夹层具有高弹性模量(或在足够快的变形下具有高弹性模量)，例如，当在30℃以每分钟10mm的伸长率测量时，弹性模量在300至1000MPa或400至600MPa的范围内。第一片20的面向内的表面和第二片70的面向外的表面对应于窗200的第三表面S3(内部)和向内表面或第四表面S4(面向住宅内)。还采用了增强的间隔件60和增强的框架(未示出)。
在飓风期间，如果风力驱动的抛射物以足够的力撞击表面S1，则片材50、第一片20和第二片70都可能因冲击而破裂，但如果窗200按预期作用，则聚合物夹层40即使在片材50、第一片20和第二片材70破裂之后，仍保持完好无损并且保持密封在窗框内，从而防止风和风夹带的水穿过窗200而进入住宅内。为了使聚合物夹层40能够承受这种冲击，层压窗格件12的第一片20和第二片70被热强化，这意味着它们被热回火以产生通常在约24至52MPa(3,500至7,500psi)范围内的表面压缩。(片材50通常也被热强化。)
如果第一片20和第二片70没有被热强化，则它们在受到冲击时往往破裂成大的、锋利的碎片，这些碎片会撕裂，刺穿或以其他方式损坏夹层40，从而导致其无法维持期望的密封。期望提供一种具有较低制造工艺成本的抗飓风窗，例如通过避免不必要的热强化来实现，同时该抗飓风窗仍保留或甚至改善其他窗性能。
发明内容
根据本公开的一些方面，提供了一种轻质的抗飓风层压窗格件，其包括厚度在2至24mm范围内的第一片的热强化玻璃，厚度在0.3至1mm范围内的第二片的未回火玻璃，以及在第一片和第二片之间且粘附于第一片和第二片的聚合物夹层。使用薄的第二片使得第二片能够以未回火的形式使用，从而减轻重量(通过薄化)并节省工艺成本(因为无需进行回火)。
根据一些方面，第一片是钠钙硅酸盐玻璃片。
根据一些方面，第二片是钠钙硅酸盐玻璃片。
根据本公开的另一些方面，第二片是硼铝硅酸盐玻璃片，或碱土金属硼铝硅酸盐玻璃片，或无碱硼铝硅酸盐玻璃片。
根据一些方面，第二片的厚度在0.85至0.4mm或0.8至0.45mm的范围内。
作为另一个方面，还公开了一种包括根据上述任何一个方面的层压窗格件的窗。
根据本公开的一些方面，一种形成抗飓风层压窗格件的方法包括：将厚度在2至24mm范围内的第一片的玻璃进行热强化，并使用聚合物夹层，将第一片的玻璃层压于厚度在0.3至1mm范围内的第二片的未回火玻璃。
根据一些方面，抗飓风窗包括厚度在2至24mm范围内的外窗格件，以及内层压窗格件，该内层压窗格件包括厚度在2至24mm范围内的第一片的热强化玻璃，厚度在0.3至1mm范围内的第二片的未回火玻璃，以及在第一片和第二片之间且粘附于第一片和第二片的聚合物夹层。
根据一些方面，抗飓风窗的层压窗格件面的第一片面向外窗格件。
根据一些方面，抗飓风窗的层压窗格件面的第二片面向外窗格件。
在以下的具体实施方式中给出了本公开的其他特征和优点，其中的部分特征和优点对本领域的技术人员而言根据所作描述即容易理解，或者通过实施包括以下具体实施方式、权利要求书以及附图在内的本文所述方法而被认识。
应理解，前面的一般性描述和以下的具体实施方式都显示了本公开的各个实施方式，并旨在提供用于理解权利要求的性质和特性的总体评述或框架。包括的附图提供了对本公开的进一步的理解，附图结合于本说明书中并构成说明书的一部分。附图例示了本公开的各个实施方式，并与说明书一起用来解释本公开的原理和操作。
附图说明
结合以下附图阅读时，可以进一步理解以下具体实施方式，其中：
图1是根据本公开的一些方面的窗或IGU的截面图；
图2是根据本公开的一些方面的窗或IGU的另一截面图；
图3(现有技术)是现有技术的抗飓风窗的截面正视图。
具体实施方式
现在将参考图1-2讨论本公开的各个方面，图1-2示出了层压窗格件的各方面，以及采用这种窗格件的窗及其组件、特征或特性。以下总体说明旨在提供所要求保护的装置的总体评述，并将参考非限制性描述的方面在整个公开文本中对各个方面进行更具体的论述，这些方面通常在本公开的上下文中可彼此互换。
参考图1，本文公开了一种轻质的抗飓风层压窗格件12和采用这种窗格件的窗100。窗格件12包括厚度在2至24mm范围内的第一片20的热强化玻璃，厚度在0.3至1mm范围内的第二片30的未回火玻璃，以及在第一片20和第二片30之间且粘附于第一片20和第二片30的聚合物夹层40。根据包括冲击然后进行压力循环的测试，使用薄的第二片20使得第二片能够以未回火的形式成功使用，从而减轻重量(通过薄化)并节省工艺成本(因为无需进行回火)，同时仍提供抗飓风性能。
第一片20可以是钠钙硅酸盐玻璃片。
第二片30也可以是钠钙硅酸盐玻璃片。或者，第二片30可以是硼铝硅酸盐玻璃片，或碱土金属硼铝硅酸盐玻璃片，或无碱硼铝硅酸盐玻璃片。第二片的厚度可以在0.85至0.4mm或0.8至0.45mm的范围内。
一种形成抗飓风窗的改进方法包括：将厚度在2至24mm范围内的第一片20的玻璃进行热强化，并使用聚合物夹层40，将第一片20的玻璃层压于厚度在0.3至1mm范围内的第二片30的未回火玻璃。
如图1所示，层压窗格件40的第一片20可以面向抗飓风窗100的外窗格件10。如图2所示，层压窗格件40的第二片30可以面向外窗格件10。
应理解，各个公开的实施方式可以涉及与特定实施方式一起描述的特定特征、要素或步骤。还应理解，虽然以涉及一个特定实施方式的形式进行描述，但是特定特征、要素或步骤可以与各个未例示的组合或排列方式中的替代性实施方式互换或组合。
还应理解的是，本文所用术语“该”、“一个”或“一种”表示“至少一个(一种)”，而不应局限为“仅一个(一种)”，除非有明确相反的说明。因此，例如，提到的“一个部件”包括具有一个此类“部件”或者两个或更多个此类“部件”的实例，上下文有另外的明确表示除外。类似地，“多个”或“阵列”旨在表示两个或更多个，因此“部件阵列”或“多个部件”表示两个或更多个此类部件。
本文中，范围可以表示为从“约”一个具体值开始和/或至“约”另一个具体值终止。当表述这种范围时，实例包括自某一具体值始和/或至另一具体值止。类似地，当使用先行词“约”表示数值为近似值时，应理解，具体数值构成了另一个方面。还应理解，每个范围的端点在与另一个端点有关及独立于另一个端点时都是重要的。
本文表示的所有数值应理解为包括“约”，无论是否如此陈述，除非另有明确指明。然而，还应当理解的是，所述的每个数值也可以考虑是精确值，无论其是否以“约”该数值表示。因此，“小于100nm的尺寸”和“小于约100nm的尺寸”都包括“小于约100nm的尺寸”和“小于100nm的尺寸”的实施方式。
除非另有表述，否则都不旨在将本文所述的任何方法理解为需要使其步骤以具体顺序进行。因此，当方法权利要求实际上没有陈述为其步骤遵循一定的顺序或者其没有在权利要求书或说明书中以任意其他方式具体表示步骤限于具体的顺序，都不旨在暗示该任意特定顺序。
虽然使用过渡语“包含”可以公开特定实施方式的各个特征、要素或步骤，但是应理解的是，这暗示了包括可采用过渡语由“......构成”或“基本上由……构成”描述在内的替代性实施方式。因此，例如，包含A+B+C的装置的隐含的替代性实施方式包括其中装置由A+B+C组成的实施方式以及其中装置基本上由A+B+C组成的实施方式。
对本领域的技术人员而言，显而易见的是，可以对本公开进行各种修改和变动而不偏离本公开的范围和精神。因为本领域的技术人员可以想到融合了本公开的精神和实质的所公开的实施方式的各种改进的组合、子项组合和变化，因此，应认为本公开包括所附权利要求书范围内的全部内容及其等同内容。
