实施本发明的方式
下面对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明的保护范围。
实施例一
本发明实施例提供一种中空玻璃用间隔密封条，该间隔密封条可用在中空玻璃的边沿处，对中空玻璃进行密封，起到“暖边”的效果，如图1所示，该间隔密封条包括：隔离层7、粘结层1、支撑层5、隔热层4和吸附层3；
其中，隔离层7为凹槽形，所述隔离层7的两侧竖边外分别设置粘结层；
隔离层7内从下至上依次设置隔热层4和支撑层5；
吸附层3覆盖隔离层7的凹槽形的开口；
吸附层3与支撑层之间非接触处为中空层。
进一步的，上述间隔密封条中，支撑层5可采用波浪形结构，通过设置支撑层5，提高了该间隔密封条的抗压强度，同时使得该间隔密封条具有可折弯的定型性，降低水汽透过率。作为支撑层5的波浪形塑料条的波谷与吸附层3之间填充空气作为中空层，通过中空层降低了该间隔密封条的导热系数。支撑层5具体可采用每米125个波峰的波浪形塑料条（PET或PP条），波浪形铝条、尼龙材料制作波浪形结构（如波浪形尼龙条）等。
进一步的，如图2所示，上述间隔密封条还包括：增强层一2、增强层二21和增强层三22，其中，所述增强层一2粘接在支撑层4的波峰与吸附层3之间；所述增强层二21填满并粘接在所述支撑层的波谷与所述隔热层之间；增强层三22填满并粘接在隔热层4与隔离层7之间。通过增强层将隔离层7，支撑层5和隔热层4粘结为整体，实际中，增强层一2、增强层二21和增强层三22均可采用热塑性的密封胶形成的增强层，密封胶具体可采用导热系数小于0.2w/(m2.k)的高粘结，高硬度的丁基密封胶。
进一步的，上述间隔密封条中，隔离层可采用由铝塑薄膜构成的凹槽形结构。铝塑薄膜具体可采用PET/镀铝CPP、PET/AL/PE、PET/AL/CPP、PET/AL/NY/PE中的任一种，可采用水汽透过率小于0.02g/m2.24h的铝塑薄膜。
进一步的，上述间隔密封条中，粘结层可采用由丁基密封胶条形成的粘结层。可采用水汽透过率小于0.23g/m2.24h的高粘结，高强度丁基密封胶条形成的粘结层。通过粘结层可使该间隔密封条与玻璃粘结在一起，同时因为该粘结层具有极低的水汽透过率，可阻止水汽在粘接处渗入中空玻璃内。
进一步的，上述间隔密封条中，隔热层4可采用耐热塑料条。具体可采用导热系数小于0.19w/(m2.k)的低导热耐老化塑料条，通过设置隔热层4降低了整个间隔密封条的K值，便于间隔密封条成型同时也提高了间隔密封条的抗压强度。
进一步的，上述间隔密封条中，吸附层采用由气体吸附材料制成的波浪形结构。将吸附层覆盖在隔离层7的开口处，可起到吸附湿气，降低隔离层内露点，提高间隔密封条的抗紫外性能。该吸附层具有快速的水汽吸附速度，可提高使用中的施工速度。吸附层具体可采用波浪形设计，即其与空气的接触面采用波浪形，提高接触面积。该吸附层具体可采用填有气体吸附及抗紫外功能纳米填料的密封胶。
本实施例的间隔密封条：由于吸附层覆盖隔离层的开口，具有更优异的密封性能的同时，隔湿以及隔热性更好，其水汽渗透指数能小于0.1，导热系数低能小于0.1W/m.℃，并且由于密封好，可提高隔声性能1db。
实施例二
本实施例提供一种中空玻璃，如图3所示，该中空玻璃包括：
相对间隔设置的至少两片玻璃30、31，两片玻璃30、31的边沿处设有作为密封结构的间隔密封条32，所述密封密封条32采用上述实施例一给出的间隔密封条，间隔密封条两侧的粘接层与两片玻璃密封粘接，间隔密封条的吸附层一侧朝向两片玻璃形成的中空空间内，间隔密封条的隔离层外侧设有固定密封胶层33。
实施例三
本实施例提供一种窗户，如图4所示，该窗户包括：
窗框40和设置在窗框上的中空玻璃，所述中空玻璃采用上述实施例二给出的中空玻璃。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明披露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书的保护范围为准。
