阻燃隔热保温膜
技术领域
本发明涉及一种阻燃隔热保温膜，具体涉及一种阻燃、隔热、保温效果优异的薄膜产品，可用于输热管、建筑物屋顶及墙壁领域以及其他有阻燃隔热保温需求的领域，特别适合对于阻燃隔热保温效果要求较高的领域。
背景技术
隔热保温膜类产品有着特殊的用途，比如用在输热管以及一些建筑物的屋顶和墙壁等，能够起到隔热保温节能降耗等作用。不同的用途和场合对于隔热保温膜类产品的要求也有所不同，有些还需要有阻燃功能。但是现有技术中具有阻燃功能的隔热保温膜产品不多，市面上几乎都是易燃隔热产品。一些具有阻燃功能的阻燃隔热保温膜产品效果也并不佳，这些阻燃隔热保温膜产品一般都有侧重点，有些产品更侧重于隔热保温效果效果，而阻燃性能并不是很好，有些产品则是更侧重于阻燃，而隔热保温效果并不是很好，有些产品为了达到更好的效果采用了复杂的层结构，并且导致产品极厚，对于一些要求阻燃、隔热和保温性能都要优异并且还需要产品轻薄的领域来说，现有技术的阻燃隔热保温膜产品都无法完美胜任。因此，亟待开发一种阻燃、隔热、保温性能都十分出色并且结构简单的膜产品来适应高要求的用途领域。
发明内容
为了解决上述问题，本发明提供了一种阻燃隔热保温膜，该阻燃隔热保温膜的反射层的高反射性能以及气囊层的高保温性能使得该阻燃隔热保温膜具有优异的隔热保温效果，而且阻燃等级达到UL94-0，又且该阻燃隔热保温膜抗拉强度高、更经济化。
本发明为了解决其技术问题所采用的技术方案是：
一种阻燃隔热保温膜，由第一反射层、阻燃多层气囊层和第二反射层依次叠合构成，其中，所述第一反射层和所述第二反射层皆为由位于内侧的高反射率铝箔和位于外侧的高透光率塑料膜通过粘着剂层粘接构成的复合层，所述高反射率铝箔是指在可见光波长0.38-0.765m范围内反射率为75％-85％并且在红外线波长0.76-505m范围内反射率为80％-98％的铝箔，所述高透光率塑料膜是指透光率为95％以上的塑料膜，所述阻燃多层气囊层由至少两层阻燃气囊层构成。
本发明为了解决其技术问题所采用的进一步技术方案是：
进一步地说，所述第一反射层的总厚度和所述第二反射层的总厚度皆为14-70μm，其中，所述高反射率铝箔的厚度为5-20μm、所述高透光率塑料膜的厚度为8-30μm，所述粘着剂层的厚度为1-20μm。优选的是，所述第一反射层的总厚度和所述第二反射层的总厚度皆为22-43μm，其中，所述高反射率铝箔的厚度为7-15μm、所述高透光率塑料膜的厚度为12-18μm，所述粘着剂层的厚度为3-10μm。
进一步地说，所述阻燃多层气囊层的气囊为圆饼状且大小规格d×h为5㎜×1㎜-40㎜×15㎜，其中，d为气囊的直径，h为气囊的厚度。可以是，所述阻燃多层气囊层中的气囊的大小规格相同；也可以是，所述阻燃多层气囊层中位于同一层的气囊大小规格相同且位于不同层的气囊大小规格不同。
当所述阻燃多层气囊层中的气囊的大小规格相同时，所述气囊的大小规格优选的是d×h为10㎜×4㎜。
当所述阻燃多层气囊层中位于同一层的气囊大小规格相同且位于不同层的气囊大小规格不同时，优选的是，所述阻燃多层气囊层由两层阻燃气囊层构成，且一层阻燃气囊层中的气囊的大小规格d×h为10㎜×4㎜，另一层阻燃气囊层中的气囊的大小规格d×h为20㎜×7㎜。
进一步地说，所述高透光率塑料膜为PP膜、PET膜、PE膜和PEN膜中的一种，所述粘着剂层的材料采用阻燃型或非阻燃型的聚氨脂类、丙烯酸类、环氧类和酚醛类中的至少一种，所述阻燃多层气囊层侧材料采用改性阻燃聚乙烯系。
优选的是，所述粘着剂层的材料采用聚氨脂类和丙烯酸类中的至少一种。
本发明的有益效果是：本发明的阻燃隔热保温膜由第一反射层、阻燃多层气囊层和第二反射层依次叠合构成，其中，第一反射层和第二反射层皆为由位于内侧的高反射率铝箔和位于外侧的高透光率塑料膜通过粘着剂层粘接构成的复合层，阻燃多层气囊层由至少两层阻燃气囊层构成，由于反射层是由高反射率铝箔和高透光率塑料膜通过粘着剂层粘接构成，较之现有技术采用普通铝箔(在可见光波长0.38-0.765m范围内反射率可达55％-65％，在红外线波长0.76-505m范围内反射率可达60％-85％)形成的反射层以及在此基础上再以淋膜方式形成塑料表层(透光率为75-85％)的反射层，本发明的反射层具有高反射率、高阻热、优异导热系数及高抗拉强度；本发明采用阻燃多层气囊层替代传统单层易燃隔热材料，使产品阻燃等级达到UL94-0，而且也提升了隔热保温性能；特别当不同气囊层采用不同气囊大小配比时，在达到优异隔热效果的同时能够比现有技术单一大小气囊结构更经济。
