Abstract

一种透明隔热装饰膜,它是在透明基膜上,例如聚酯薄膜、聚丙烯薄膜上以物理气相淀积一薄层半导体化合物二氧化锡,再以同样的方法淀积一薄层银合金或铝合金,形成介质金属D/M非对称结构的透反膜层,然后使用涂布的方法涂敷一层粘接剂和隔离层。
由它发展成的彩色透明隔热布是最佳的遮阳篷布。
由它发展成的彩色透明隔热塑片,是形成新型透明隔热的多色百叶窗帘的新型材料。

Description

透明隔热装饰膜,涉及薄膜光学领域。
目前,世界上生产单色和隔热膜很多,美国3M公司生产白色的透明隔热膜,其透光性和隔热效果均较佳,但是该产品的可见光反射率太高,全波段反射率大干60%。因为耀眼的反光会干扰正常的秩序,所以在有些场合被禁止使用。例如,耀眼的反光会影响交通安全,所以被禁止使用在汽车的帧膜上。
本发明旨在给出一种大面积的透明隔热膜,既保证较佳的透光性和隔热效果,又减少了全色反光率,抑制了耀眼的“镜面效应”,使之达到隔热、装璜、调光和节能的多功能效果。
实验表明,现有建筑物内的热源(热炉、空调、人体等)辐射出来的能量80%以上是波长大于3um的红外线热量,室内外的热对流、热传导可通过1—2层玻璃窗得到基本控制。而热辐射是现有建筑物窗户的主要热能损失形成,若在窗户通道上增加一层红外宽谱反射层,同时对可见光波段有较大的透光率,则可使作为光、热交换通道的建筑物窗户成为既透光又隔热的“透明墙”。
根据以上思路,本发明在透明基膜上,例如聚酯薄膜(PET)、聚丙烯薄膜(BOPP)等上用物理气相淀积(PVD)的方法淀积一薄层半导体化合物,如二氧化锡(SnO2),再以同样的方法淀积一层银合金或铝合金,形成介质金属D/M非对称结构的透反膜层,然后使用涂布的方法涂敷一层粘接剂,可供用户使用。
单色光学膜层的银合金或铝合金的薄层厚约50A~500A°,最佳为120A°。
本发明的透明隔热装饰膜与疏经纬纤维布粘接复合而成防水透光隔热布。
本发明与耐紫外老化的透明塑料厚膜粘接复合可制作透明隔热百叶窗的叶片材料。
本发明具有明显的隔热保温作用,可使空调室节能30%以上,温度下降2~3℃;具有优良的调光作用,透光率可达20%—50%。由于对紫外光的透射率接近为零。因此,具有较好的保护作用,并且还具有高品味的装饰效果。
实施例:在透明基膜(1)上,例如聚酯薄膜(PET)、聚丙烯薄膜(BOPP)等上以物理气相淀积(PVD)的方法淀积一薄层半导体化合物二氧化锡(SnO2),(2),以同样的方法再淀积一薄层银合金或铝合金(3),形成介质金属D/M非对称结构透反膜层,得到单色的光学膜层,然后以涂布的方法涂敷一层粘接剂(4)和隔离层(5)。
半导体化合物二氧化锡和银合金或铝合金,厚约50A°~500A°,最佳为120A°。
本发明的透明隔热装饰膜与疏经纬纤维布粘接复合(6),可制作隔热伞、遮阳蓬布、彩色防水透光隔热布(7)等。
本发明的透明隔热装饰膜与耐紫外老化的透明塑料厚膜粘接复合(6),可制成彩色透明隔热百叶窗的叶片材料(7)。
