Description

大棚用保温被
技术领域
本发明属于大棚保温技术领域，涉及一种保温被，具体的说，涉及一种大棚用保温被。
背景技术
大棚种植技术是农业重要的技术领域，受季节影响较小，是保证农作物常年供应的重要手段。为保持大棚种植环境，大棚表面需要覆盖材料对其保温，目前保温覆盖物多以稻草毡和多层无纺布棉毡保温被为主。这两种保温覆盖物都存在很大的缺陷，稻草毡厚重，雨水侵湿后，吸水更重，保湿效果差，使用年限短，稻草毡的卷放需要卷帘机械功率大，造价高，易损伤大棚薄膜；无纺布棉毡保温被在雨雪天吸水潮湿后，保温性能降低；吸水冷冻结冰后，无法卷放，丧失使用功能。目前，大棚保温被正逐步取代稻草毡和无纺布棉毡的保温结构，现有的大棚保温被多在具有一定的防潮、保温效果，但在综合效果上仍存种很大的不足。但市场上的大棚保温被品种多样，结构也多样，多存在保温防潮效果不佳等不足。
发明内容
本发明的目的在于针对现有技术的不足，提供一种防潮、保温效果好的大棚用保温被。
本发明的技术方案是：一种大棚用保温被，由外到内依次为外防水层、外保温层、内保温层和导热层，外防水层采用PVC防水布，外保温层采用保温棉，内保温层采用聚乙烯泡沫，导热层采用铝箔。
优选的是：外保温层的厚度为10～20mm。
优选的是：内保温层的厚度为10～20mm。
本发明的有益效果是：本发明结构简单、容易实现，外防水层、外保温层、内保温层和导热层的结构可实现较好的保温效果，保温棉和聚乙烯泡沫均具有较好的保温性，铝箔层有较好的导热性，使大棚内可获得较好的环境温度。
附图说明
附图1为本发明的结构示意图
具体实施方式
以下结合附图对本发明做进一步详细的说明。
