Description
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
