Description

一种隔热功能好的反光膜
技术领域
本发明涉及反光膜领域，具体的说，是一种隔热功能好的反光膜。
背景技术
膜是具有选择性分离功能的材料，利用膜的选择性分离可实现固体、液体、气体、光线等的分离，这种分离过程为物理过程，不包含相的变化或者添加助剂。目前，膜技术在日常生活中也日益显示出它的重要作用和光明前景，其中以光学膜和水膜的作用尤为显著，光学膜常适用于建筑、汽车、摄影、电子元器件等领域，光学膜主要包含高透膜、高反膜、减反射膜、反光膜、遮光膜等等。
目前市场上的反光膜，其面层主要采用丙烯酸酯树脂，聚酯树脂，聚乙醇缩丁醛树脂，聚氯乙烯树脂，聚对本二甲酸乙二醇酯树脂和聚氨酯树脂等，这些树脂由于表面极性等原因，容易粘附灰尘，影响了反光膜的透明性，从而影响反光膜的最主要性能逆反射系数，降低了反光膜的主要功能，并且现有的反光膜逆反射性能较差、性能不稳定、不隔热、不隔离紫外线、厚度大、使用寿命短，不利于大规模的推广和使用。
发明内容
本发明的目的在于提供一种结构简单、防污能力强的隔热功能好的反光膜。
本发明通过下述技术方案实现：一种隔热功能好的反光膜，包括由下往上依次设置的压敏胶层、紫外线滤层、热熔胶层、反光层、隔热层和防粘污层。
所述的隔热层为由聚对苯二甲酸乙二酯、聚对苯二甲酸丁二酯、聚芳香酯和聚酯无纺布纤维制成的隔热层。
所述的反光层内设有若干个玻璃微珠，玻璃微珠与热熔胶层固定连接。
所述的玻璃微珠与热熔胶层之间设有反光膜。
所述的玻璃微珠为高折射率玻璃微珠。
所述的防粘污层采用硅油、石蜡或聚四氟乙烯树脂中的一种或多种制成。
所述的防粘污层设有防粘污层保护膜。
所述的压敏胶层外侧设有压敏胶层保护膜。
本发明与现有技术相比，具有以下优点及有益效果：
（1）本发明通过设置隔热层能够通过本发明起到隔热的作用，避免膜外侧的高低温影响膜内侧的温度，通过设置防粘污层能够提高反光膜的防污能力，防止灰尘、油污等污渍对反光膜的使用带来负面影响；
（2）本发明通过选用硅油、石蜡或聚四氟乙烯树脂制成防粘污层，能够使反光膜的表面张力小于25mN/m，使反光膜不容易粘附灰尘，即使粘上灰尘后也容易清洗，并且具有良好的透明性，不影响原有反光膜的颜色和性能；
（3）本发明通过选用由聚对苯二甲酸乙二酯、聚对苯二甲酸丁二酯、聚芳香酯和聚酯无纺布纤维制成的隔热层能够使得隔热率大于或等于80%，其具有隔热效果好等优点，并且有利于防止高温对玻璃微珠的粘黏造成影响。
