Description
技术领域
本发明涉及夹层玻璃。
背景技术
在1对玻璃板之间设有树脂等中间膜的夹层玻璃由于在破损时碎片不会飞散、安全性优良,被广泛用于车辆或建筑物的窗玻璃等。近年,使用在飞散防止等安全性以外、赋予了各种功能的夹层玻璃。尤其,迫切需求兼顾轻量性和刚性和隔音性的夹层玻璃。专利文献1提出了通过具有剪切储能模量以及损耗系数在特定的范围内的中间膜而在实现轻量的同时具有刚性和隔音性的夹层玻璃。
现有技术文献
专利文献
专利文献1:日本专利特开2017-65966号公报
发明内容
发明所要解决的技术问题
但是,如专利文献1的刚性优良的夹层玻璃,其中间膜中含有的增塑剂由于热量、光以及水的影响而容易渗透、中间膜的端部容易发生边缘发泡的问题。
本发明是鉴于上述课题而产生的,目的在于提供耐边缘发泡性和刚性优良的夹层玻璃。
解决技术问题所采用的技术方案
本发明人为了解决上述的课题而认真研究,结果发现,刚性优良的夹层玻璃用中间膜存在由于其中间膜中含有的增塑剂容易渗透而不易保持增塑剂的问题,从而完成了本发明。
即,本发明提供一种夹层玻璃,其是层叠有一对玻璃板、和设于该一对玻璃板之间的包括增塑剂的中间膜的夹层玻璃,其特征在于,上述中间膜的剪切储能模量G’为2~100MPa,上述中间膜的外周端在上述夹层玻璃的至少一部分中存在于比上述一对玻璃板的2块玻璃板的外周端更内侧的位置。
发明的效果
如果采用本发明,则可提供耐边缘发泡性和刚性优良的夹层玻璃。
附图说明
图1是表示本发明的夹层玻璃1的一例的端部的部分示意剖面图。
图2是表示本发明的夹层玻璃1的一例的端部的部分示意剖面图。
图3是表示本发明的夹层玻璃1的一例的示意主视图。
具体实施方式
以下,对本发明的实施方式进行说明,但本发明并不局限于以下的实施方式。本申请说明书中,在没有特别定义的范围内,“~”表示包括记载在其前后的作为下限值和上限值的数值。
图1是表示本发明的夹层玻璃1的一例的端部的部分剖面图。夹层玻璃1是层叠有由第一玻璃板2以及第二玻璃板3构成的一对玻璃板、和设于该一对玻璃板之间的中间膜4的夹层玻璃。中间膜4的外周端存在于比第一玻璃板2以及第二玻璃板3的外周端更内侧的位置,即接近夹层玻璃的面内中心部的一侧。第一玻璃板2以及第二玻璃板3的外周端大致相同,即第一玻璃板2以及第二玻璃板3的外周端相当于夹层玻璃1的外周端。
图2是示出本发明的夹层玻璃1的端部的其它例的部分剖面图。
此处,D表示中间膜4的外周端与一对玻璃板的2块玻璃板的外周端的距离,即第一玻璃板2的露出长度或第二玻璃板3的露出长度(以下,也称为露出长度D),在第一玻璃板2的露出长度与第二玻璃板3的露出长度不同的情况下,指较短一方的长度。
此外,E表示第一玻璃板2的外周端和第二玻璃板3的外周端的距离(以下,也称为板位移宽度E)。
在将夹层玻璃1用于车辆用的情况下,第一玻璃板2被配置在车内侧,第二玻璃板3被配置在车外侧。在将夹层玻璃1用于建筑用的情况下,第一玻璃板2被配置在室内侧,第二玻璃板3被配置在室外侧。
图3是表示本发明的夹层玻璃1的一例的主视图,虽然以车辆用侧窗玻璃为例示出,但本发明的夹层玻璃1的用途不限于车辆用侧窗玻璃。夹层玻璃1具有上边缘部5、下边缘部6以及二个侧边缘部7。夹层玻璃1的外周端由上边缘部5、下边缘部6以及二个侧边缘部7形成。表示中间膜4的外周端的虚线存在于夹层玻璃1的比整个外周端更内侧的位置。
(夹层玻璃)
本发明的夹层玻璃1是层叠有一对玻璃板、和设于一对玻璃板之间的中间膜4,中间膜4的剪切储能模量G’为2~100MPa的夹层玻璃。而且,中间膜4的外周端在夹层玻璃1的外周端的至少一部分中、存在于比一对玻璃板的2块玻璃板的外周端更内侧。
具有上述的构成的本发明的夹层玻璃1的耐边缘发泡性优良。其理由虽不明确,但推测如下。
与使用了剪切储能模量G’不足2MPa的中间膜的夹层玻璃相比,使用了剪切储能模量G’为2~100MPa的中间膜的夹层玻璃长期使用不易发生边缘发泡。边缘发泡因中间膜中含有的增塑剂由于紫外线、热量以及水的影响发生渗透而引起。因此,本发明的夹层玻璃1中,通过使中间膜4的外周端存在于比一对玻璃板的2块玻璃板的外周端更内侧的位置,可保护中间膜4的端部不被热量以及紫外线影响。通过该保护效果,中间膜4中含有的增塑剂不易渗透到端部中,因此本发明的夹层玻璃1的耐边缘发泡性优良。
图3中,表示中间膜4的外周端的虚线存在于夹层玻璃1的比整个外周端更内侧的位置。即,中间膜4的外周端在夹层玻璃1的整个外周中,存在于比构成一对玻璃板的2块玻璃板的外周端更内侧的位置。但是,也可以是在夹层玻璃1的整个外周的一部分中,中间膜4的外周端位于比构成一对玻璃板的2块玻璃板的外周端更内侧的位置。即,在夹层玻璃1的整个外周的至少一部分中,中间膜4的外周端存在于比构成一对玻璃板的2块玻璃板的外周端更内侧的夹层玻璃1由于在其部分中,中间膜4的端部被保护而不受热量以及紫外光的影响,因此具有优良的耐边缘发泡性。只要将本发明的构成用于夹层玻璃1中需要耐边缘发泡性的部分即可。
如前所述,图2所示的露出长度D是指夹层玻璃1的侧面或切断面中的、第一玻璃板2的露出长度和第二玻璃板3的露出长度中的较短一方的长度。第一玻璃板2的露出长度是指通过第一玻璃板2的最前端部、与板厚方向平行的直线和通过中间膜4的最前端部、和与上述的板厚方向平行的直线平行的直线的最短距离。第二玻璃板2的露出长度是指通过第二玻璃板3的最前端部、与板厚方向平行的直线和通过中间膜4的最前端部、和与上述的板厚方向平行的直线平行的直线的最短距离。
夹层玻璃1中,中间膜4的外周端位于比一对玻璃板的2块玻璃板的外周端更内侧的外周的比例优选为夹层玻璃1的整个外周中的20%以上。通过使上述外周的比例在20%以上,保护中间膜4的端部不受热量以及紫外线影响,因此具有优良的耐边缘发泡性。上述外周的比例更优选30%以上,进一步优选40%以上,特别优选50%以上。
中间膜4的外周端存在于比一对玻璃板的2块玻璃板的外周端更内侧0.2~1.0mm的位置,即露出长度D优选0.2~1.0mm,更优选0.3~0.8mm,进一步优选0.4~0.7mm。如果露出长度D在下限值以上,则容易保护中间膜4的端部不受热量以及紫外线影响,因此提高了夹层玻璃1的耐边缘发泡性,如果露出长度D在上限值以下,则中间膜4的端部变得不显眼,作为夹层玻璃的美观性提高。
在将夹层玻璃1作为例如车辆用窗玻璃安装在车辆上的情况下,优选一对玻璃板的至少一方的上边缘部的至少一部分从中间膜4的外周端露出。例如,在将图3示出的夹层玻璃1用于车辆用侧窗玻璃的情况下,夹层玻璃1的上边缘部5在升降时露出,与下边缘部以及侧边缘部相比,更容易受到热量和紫外线的影响。因此,夹层玻璃1的上边缘部5中,通过使一对玻璃板相对于中间膜4露出,可提高车辆用侧窗玻璃用途中的夹层玻璃1的耐边缘发泡性。而且,在夹层玻璃1的侧边部中,根据与上边缘部相同的理由,通过使一对玻璃板相对于中间膜4露出,可提高车辆用侧窗玻璃用途中的夹层玻璃1的耐边缘发泡性。
另外,本说明书中,“上边缘部”以及“下边缘部”是指将夹层玻璃安装在车辆上时作为上侧以及下侧的边缘,“侧边缘部”是指其它2个边缘。另外,“上边缘部”是指夹层玻璃的上边缘附近的区域,“下边缘部”是指夹层玻璃的下边缘附近的区域。
一对玻璃板优选一个玻璃板的外周端存在于比另一个玻璃板的外周端更内侧的位置,也就是一对玻璃板没有对准(板ずれがある)。如果一对玻璃板没有对准,则有效地保护中间膜4的端部不受热量以及紫外线影响,因此可进一步提高夹层玻璃1的耐边缘发泡性。例如,在将夹层玻璃1用于车辆用途或建筑用途的情况下,优选车内侧或室内侧的玻璃板的外周端存在于比车外侧或室外侧的玻璃板的外周端更内侧(即,接近夹层玻璃的面内中心部一侧)的位置。如果是这样的构成,则由于最有效地保护中间膜4的端部不受从车外或室外进入的热量以及紫外线影响,因此可提高夹层玻璃1的耐边缘发泡性。
如图2所示,板位移宽度E是指夹层玻璃1的侧面或切断面中的、通过第一玻璃板2的最前端部与板厚方向平行的直线和通过第二玻璃板3的最前端部与板厚方向平行的直线的最短距离。即,是指第一玻璃板2的露出长度和第二玻璃板3的露出长度之差。
一对玻璃板的板位移宽度E优选0.2~0.8mm,更优选0.3~0.7mm,进一步优选0.3~0.6mm。如果板位移宽度E在下限值以上,则更有效地保护中间膜4的端部不受热量以及紫外线影响,因此可提高夹层玻璃1的耐边缘发泡性。如果板位移宽度E在上限值以下,则中间膜4以及第二玻璃板2的端部变得不显眼,作为夹层玻璃的美观性提高。
夹层玻璃1根据JIS R 3106:1998测定的可见光透过率优选为70%以上。如果可见光透过率在70%以上,则可充分确保识别性,进而可使设置于玻璃板的各种传感器充分起作用。
夹层玻璃1根据JIS R 3106:1998测定的太阳光透过率Te优选5~60%,进一步优选35~55%。如果太阳光透过率Te在上述范围内,则可提高夹层玻璃1的遮热性。
夹层玻璃1优选还具有功能性薄膜或功能性膜。功能性薄膜或功能性膜设于第一玻璃板2和中间膜4之间、中间膜4的内部、第二玻璃板3和中间膜4之间等。作为功能性薄膜,可例举紫外线截止薄膜或红外线截止薄膜。作为功能性膜,可例举紫外线截止膜或红外线截止膜。作为红外线截止膜,可例举以将银作为主要成分的层***于电介质层之间的方式层叠而得的结构的多层膜。作为紫外线截止膜,可例举包含紫外线吸收剂的二氧化硅膜。
夹层玻璃1中,第一玻璃板2和第二玻璃板3之间的间隔优选从面内中心部起向着外周端变小。通过该构成,中间膜4的增塑剂不易由于紫外线、热量以及水而渗透,耐边缘发泡性提高。
(玻璃板)
作为一对玻璃板的第一玻璃板2以及第二玻璃板3可使用白色系钠钙玻璃、绿色系有色钠钙玻璃、紫外线遮蔽性有色钠钙玻璃、热线吸收性有色钠钙玻璃、化学强化的铝硅酸盐玻璃等。热线吸收性有色钠钙玻璃具有源于白色系玻璃的组成、增加了总氧化铁的含有比例、TiO2的含有比例、CeO2的含有比例的组成。换算为Fe2O3的全铁量优选0.5~1.0质量%。藉此,夹层玻璃1的遮热性优良、且可得到安全上必须的可见光透过率。此外,全铁量中所占的2价氧化铁的比例(也称为氧化还原电势比)优选20~30质量%,更优选22~27质量%,进一步优选24~25质量%。
第一玻璃板2以及第二玻璃板3的至少一个玻璃板根据ISO9845-1:1992测定的紫外线透过率Tuv优选65%以下,更优选60%以下。如果Tuv在上述上限值以下,则更有效地保护中间膜4的端部不受紫外线影响,因此可提高夹层玻璃1的耐边缘发泡性。另外,即使仅配置于车外侧的第二玻璃板3的Tuv在65%以下,也可得到同样的效果。
第一玻璃板2以及第二玻璃板3的至少一个玻璃板根据JIS R 3106:1998测定的太阳光透过率Te优选75%以下,更优选70%以下。如果Te在上述上限值以下,则有效地保护中间膜4的端部不受热量影响,因此可提高夹层玻璃1的耐边缘发泡性。另外,配置于车辆的车内侧的第一玻璃板2的Te在上述上限值以下也可得到相同的效果。
配置于车辆的车外侧的第二玻璃板3优选板厚在1.6mm以上,进一步优选2.0mm以上,特别优选2.2mm以上。如果第二玻璃板3的板厚在1.6mm以上,则可具备针对小石等飞来物的耐冲击性。此外,在第二玻璃板3具有吸收紫外线的组成的情况下,可有效地抑制中间膜4的边缘发泡。第二玻璃板3优选板厚在3.0mm以下,更优选2.5mm以下,进一步优选2.1mm以下。如果第二玻璃板3的板厚在上限值以下,则可将夹层玻璃1轻量化。
配置于车辆的车内侧的第一玻璃板2优选板厚为0.6~2.0mm,进一步优选1.2~1.6mm。如果在上述范围内,则可进一步确保作为人容易听到的声音的频率区域的2000~5000Hz中的隔音性。
第一玻璃板2和第二玻璃板3的板厚差优选0.7mm以下,更优选0.4mm以下。如果第一玻璃板2和第二玻璃板3的板厚差在0.7mm以下,则频率区域2500~5000Hz中的隔音性良好。
第一玻璃板2和第二玻璃板3的外周端的周缘部优选进行倒角加工。经倒角加工的面对紫外线进行散射,中间膜4的增塑剂不易渗透。倒角加工例如通过旋转磨石实施倒角加工。旋转磨石的外周面中,形成有在周向上延伸的环状的研削沟。研削沟的壁面含有氧化铝或碳化硅、金刚石等磨粒。磨粒的粒度(JIS-R6001)例如为#120以上#2000以下。用该磨粒的粒度的磨石进行了倒角加工的面适度地成为粗糙面,对紫外线进行散射,因而优选。经倒角加工的形状优选R倒角形状。
第一玻璃板2的板厚和第二玻璃板3的板厚合计的总板厚优选4.0mm以下,进一步优选3.6mm以下。如果一对玻璃板的总板厚在上述上限值以下,则可将夹层玻璃1轻量化。一对玻璃板的总板厚优选2.5mm以上,更优选3.0mm以上。如果一对玻璃板的总板厚在上述下限值以上,则夹层玻璃1的刚性提高。
在夹层玻璃1用于车辆的情况下,也可具有弯曲形状。在用于侧窗玻璃的情况下,从夹层玻璃1的外周端起100mm以内的上下方向的曲率半径优选50000mm以下,更优选40000mm以下,进一步优选30000mm以下。如果曲率半径在该范围内,则中间膜4的外周端不易识别,外观上优选。另外,上下方向是指将侧窗玻璃安装在车辆上的状态下的方向。
(中间膜)
中间膜4的剪切储能模量G’为2~100MPa。上述剪切储能模量G’是在温度20℃、频率1Hz以及形变0.05%的测定条件下、通过通常的动态粘弹性测定方法测定的值。
中间膜4优选在从其外周端起向着内侧5mm以内的区域中,中间膜4的主面的每单位面积的增塑剂量为0.05~0.22mg/mm2。如果中间膜4的端部中含有的增塑剂量在0.05mg/mm2以上,则可确保夹层玻璃1的隔音性,如果增塑剂量在0.22mg/mm2以下,则可更有效地抑制增塑剂的渗透,因此夹层玻璃1的耐边缘发泡性提高。
中间膜4的端部的至少一部分、例如端部的中央部优选具有从该端部的外侧凹陷的U字形状。如果中间膜4的端部的至少一部分具有凹陷的U字形状,则更有效地保护中间膜4的端部不受热量以及紫外线影响,因此可提高夹层玻璃1的耐边缘发泡性。
中间膜4优选具有3层以上的层叠结构。中间膜4包含依次层叠第一树脂层、第二树脂层以及第三树脂层而得的层叠结构,第一树脂层、第二树脂层以及第三树脂层含有增塑剂,优选第二树脂层中含有的增塑剂的量比第一树脂层中含有的增塑剂的量或第三树脂层中含有的增塑剂的量更多。第一树脂层、第二树脂层以及第三树脂层通过包含增塑剂,可提高耐贯穿性和密合性。优选第二树脂层中含有的增塑剂的量比第一树脂层或第三树脂层中含有的增塑剂的量多10phr以上,更优选多20phr以上。如果在上述下限值以上,则可提高夹层玻璃1的隔音性。
作为增塑剂,可例举有机酯增塑剂或有机磷酸增塑剂等,其中优选有机酯增塑剂。
上述有机酯增塑剂优选包括二-(2-丁氧基乙基)-己二酸酯(以下,也称为DBEA)、三乙二醇二-2-乙基己酸酯(以下,也称为3GO)、三乙二醇二-2-乙基丁酸酯(以下,也称为3GH)或三乙二醇二-2-乙基丙酸酯,其中,更优选包括3GO、3GH或三乙二醇二-2-乙基丙酸酯,进一步优选包括3GO或三乙二醇二-2-乙基丁酸酯,特别优选包括三乙二醇二-2-乙基己酸酯。

作为上述增塑剂,也可并用2种以上。
增塑剂在上述以外还可含有折射率高的增塑剂。通过添加折射率高的增塑剂,在中间膜4具有2层以上的层叠结构的情况下,可在维持隔音性的同时将层的折射率差最小化。作为优选的高折射率增塑剂的具体例,可例举二丙二醇二苯甲酸酯、三丙二醇二苯甲酸酯、聚丙二醇二苯甲酸酯、苯甲酸异癸酯、苯甲酸2-乙基己酯、二乙二醇二苯甲酸酯、丙二醇二苯甲酸酯、2,2,4-三甲基-1,3-戊二醇二苯甲酸酯、2,2,4-三甲基-1,3-戊二醇苯甲酸酯异丁酸酯、1,3-丁二醇二苯甲酸酯、二乙二醇二邻甲苯酸酯、三乙二醇二邻甲苯酸酯、二丙二醇二邻甲苯酸酯、1,2-辛基二苯甲酸酯、偏苯三酸三-2-乙基己酯、双酚A双(2-乙基己酸酯)、乙氧基化壬基酚、壬基酚四乙二醇、邻苯二甲酸二辛酯、邻苯二甲酸二异壬酯、对苯二甲酸二-2-乙基己酯、二丙二醇以及二乙二醇的苯甲酸酯或它们的混合物。
第二树脂层优选增塑剂的含量为50phr以上,进一步优选50~60phr。第一树脂层或第三树脂层优选增塑剂的含量为32phr以下,进一步优选24~30phr。第一树脂层、第二树脂层以及第三树脂层通过具有上述增塑剂量,可兼顾夹层玻璃1的弯曲刚性和隔音性和耐边缘发泡性。
