Description
技术领域
本发明属于玻璃技术领域,具体涉及一种夹层隔热装饰玻璃。
背景技术
目前建筑物门窗基本上采用的是夹层玻璃或者中空玻璃来进行隔热,夹层玻璃是在两块玻璃之间夹进一层以聚乙烯醇缩丁醛为主要成分的PVB中间膜制成的。但是隔热效果难如人愿,特别是在阳光充足的地区。因此,现有夹层玻璃的隔热效果已经远远不能满足人们的需求,这就加大了人们对空调的使用,增加了居住能耗。
中空玻璃是由两层或多层平板玻璃构成。四周用高强高气密性复合粘结剂,将两片或多片玻璃与密封条、玻璃条粘接、密封。由于是中空结构,因此中空玻璃的强度往往较低,容易破碎,不够耐用。
现有技术的隔热玻璃已经不能满足人们的需求,人们需要一种隔热性能优良,同时强度高的隔热玻璃。
发明内容
针对上述的不足,本发明提供一种夹层隔热装饰玻璃,它具有隔热性能好,红外区光线透过率低,可见光区光线透过率高的优点,而且强度高。
为解决上述问题,本发明通过以下技术方案实现:
一种夹层隔热装饰玻璃,包括内玻璃层和外玻璃层,内玻璃层与外玻璃层之间设有一密闭的中空层,内玻璃层与中空层之间、中空层与外玻璃层之间均通过中间胶膜相互粘结热压复合为一体,所述外玻璃层包括相互依次粘结的内玻璃基片、中间夹层和外玻璃基片,所述中间夹层包括红外光膜、紫外光膜和设于红外光膜与紫外光膜之间的PVB膜,所述红外光膜设于内玻璃基片一侧、紫外光膜设于外玻璃基片一侧。
上述方案中,为进一步提高玻璃的隔热作用及防辐射能力,可在外玻璃基片的表面镀有一低辐射层。
上述方案中,进一步地,所述低辐射层可以为Ag膜层、AgTi膜层或纳米二氧化钛层中的任意一种,且在低辐射层的表面设有一保护层。
上述方案中,为进一步提高玻璃制品的隔热效果,可以在中空层与外玻璃层之间设有一金属夹层,所述金属夹层为穿孔金属板或金属编制网、其厚度为0.2-0.5mm。
上述方案中,所述中空层内充盈有干燥的惰性气体。
上述方案中,所述外玻璃层具体可以为中空玻璃,所述内玻璃层具体可为浮法玻璃或超白玻璃。
上述方案中,粘结热压为一体后的内玻璃层和外玻璃层的四周安装有一铝合金防护框。
与现有技术相比,本发明的有益效果为:
1、本发明夹层隔热装饰玻璃主要由内玻璃层、中空层、金属夹层和外玻璃层构成,并在中空层内充有干燥气体,由于气体的热传导率远远低于玻璃、并结合中空玻璃具有隔热隔音特性,提高了夹层隔热装饰玻璃的隔热效果;
2、本发明外玻璃层为多层结构,即在内玻璃基片和外玻璃基片之间一中间夹层,该中间夹层由红外光膜、PVB膜和紫外光膜构成,且在外玻璃基片的表面镀有低辐射层,进一步地提高了夹层隔热装饰玻璃的隔热效果。
附图说明
图1为本夹层隔热装饰玻璃的一种内部结构示意图。
图2为所述外玻璃层的一种内部结构示意图。
图中标号为:1、内玻璃层;2、外玻璃层;3、铝合金防护框;4、中空层;5、内玻璃基片;6、中间夹层;7、外玻璃基片;8、红外光膜;9、紫外光膜;10、PVB膜;11、低辐射层;12、金属夹层。
具体实施方式
下面结合具体实施例和附图对本发明进行进一步的解释说明,但不用以限制本发明。
如图1所示,一种夹层隔热装饰玻璃,包括内玻璃层1和外玻璃层2,内玻璃层1与外玻璃层2之间设有一密闭的中空层4,内玻璃层1与中空层4之间、中空层4与外玻璃层2之间均通过中间胶膜相互粘结热压复合为一体。本实施例中,在中空层4与外玻璃层2之间设有一金属夹层12,所述金属夹层12为穿孔金属板或金属编制网、其厚度为0.2-0.5mm。可通过改变穿孔的孔径大小或编制网的网径大小来改变金属夹层12的隔热效果以提高整个玻璃制品的隔热效果。
所述中间胶膜可以为SGP胶或PVB胶。
进一步地,粘结热压为一体后的内玻璃层1和外玻璃层2的四周安装有一铝合金防护框3。
本实施例中,所述中空层4内具体充盈有干燥的惰性气体。所述惰性气体具体可为氦气、氖气、氩气等。
本实施例中,所述外玻璃层2具体为中空玻璃,所述内玻璃层1为浮法玻璃或超白玻璃。为增强玻璃安装使用时的立体感及装饰效果,可在内玻璃层1内嵌入图案。
如图2所示,所述外玻璃层2包括相互依次粘结的内玻璃基片5、中间夹层6和外玻璃基片7。本实施例中,所述内、外玻璃基片(5、6)可均为透明平板玻璃。所述中间夹6包括红外光膜8、紫外光膜9和设于红外光膜8与紫外光膜9之间的PVB膜10。即红外光膜8和紫外光膜9是通过PVB膜来进行粘结热压一起。所述红外光膜8设于内玻璃基片5一侧、紫外光膜9设于外玻璃基片7一侧。为进一步吸收紫外线,提高室内的舒适度,可在外玻璃基片7的表面镀有一低辐射层11。
所述红外光膜8具体由现有能够吸收红外线的光膜材料制成,所述紫外光膜9具体由现有能够吸收紫外线的光膜材料制成。
本实施例中,所述低辐射层11具体为Ag膜层、AgTi膜层或纳米二氧化钛层中的任意一种,且在低辐射层11的表面设有一保护层。当所述低辐射层11为Ag膜层、AgTi膜层时,所述保护层为TiO2层或SnO2层,以防止Ag的氧化;当所述低辐射层11为纳米二氧化钛层时,所述保护层可以为透明贴膜或透明胶膜,以纳米二氧化钛的脱落。
以上仅为说明本发明的实施方式,并不用于限制本发明,对于本领域的技术人员来说,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
