Abstract

一种覆膜保温套管,由聚乙烯材料多层高温复合制成保温套管后,采用辊筒热辊压法在保温套管外层覆合一层格状保护膜,制造工艺简单,保温管的抗拉强度和耐温差性能大大提高。

Description

覆膜保温套管
本实用新型涉及一种保温套管。
目前管道保温所采用的方法通常是用岩棉或玻璃棉粘合成有开口的套管套在管道上,再进行紧固;或者是用聚胺脂等原料用发泡的方法对管道保温。前者的缺点是防水性和保温性差,对人体有危害;后者的缺点是施工复杂,有时会造成人体中毒。最近市场上还出现了一种聚乙烯板材多层复合的管式保温套,保温效果大大提高,但抗温差性和抗拉强度还不够理想。
本实用新型的目的是提供一种覆膜保温套管。
本实用新型的目的是这样实现的:聚乙烯保温材料多层复合达到所需厚度后,用辊筒热辊压的方法在保温材料外层覆合一层保护膜,其花纹为格状。
本实用新型在覆合一层保护膜后,大大提高了保温套管的抗拉强度和抵抗温度变化的性能,而且覆膜工艺简单、成本低。
下面结合附图详细说明本实用新型的结构和工作状况。
图1是本实用新型保护膜示意图。
本实用新型在聚乙烯保温材料借助热源多层复合达到所需厚度后,采用辊筒热辊压的方法在保温材料的外层覆合一层保护膜,通常是聚乙烯膜、BOPP膜或铝膜,保护膜花纹为格式,易于覆合、工艺简单、成本低。
