Description

一种隔热保温农用薄膜
技术领域
本发明涉及塑料薄膜技术领域,特别涉及一种隔热保温农用薄膜。
背景技术
随着经济的发展以及农村产业结构的调整,中国农村产业对塑料薄膜的市场需求不断上升。为了适应农业生产各个方面的需要,农用塑料薄膜有各种不同的品种和规格。塑料薄膜在农村种植业中被广泛应用在塑料大棚领域,利用塑料大棚进行蔬菜、花卉等的设施栽培,对缓解蔬菜淡季的供求矛盾起到了特殊的重要作用,具有显著的社会效益和现实的巨大的经济效益。
但现有棚膜在使用过程中存在一些问题,如白天射入大棚内地面的红外辐射能量在夜间经棚膜散失,大幅度降低棚温,尤其是聚烯烃流滴棚膜在夜间的散热比普通膜还要快;另一方面,大量红外线进入棚中,尤其是在中午,使得棚温过高而灼烧农作物。
发明内容
为解决上述存在的问题,本发明的目的在于提供一种隔热保温农用薄膜。所述隔热保温农用薄膜,表面光滑平整,且在不明显降低透明度的前提下,大幅度提高薄膜的红外阻隔率,从而达到隔热保温的效果,省去大棚内供暖措施,节省了能源,具有广泛的应用价值。
为达到上述目的,本发明的技术方案是:
