Abstract

本实用新型是由钢质金属管道[1],防腐底漆[2],改性沥青底胶[3],聚乙烯基膜[4]组成防腐管道。这种防腐管道外防腐胶带厚度均匀,底胶层厚,与钢管表面及基膜背面粘接强度较高。

Description

沥青基聚乙烯胶带防腐管
本实用新型涉及一种埋地钢质金属管道外冷缠改性沥青底胶聚乙烯防腐胶粘带防腐管。
埋地钢质金属管道外防腐层目前有热石油沥青缠玻璃丝布防腐结构、环氧煤沥青缠玻璃丝布防腐结构、涂刷煤焦油瓷漆、冷缠丁基橡胶聚乙烯胶带和冷缠压敏胶聚乙烯胶带,前三种防腐层存在着钢质金属管道外防腐作业时污染环境,防腐层厚薄不均,防腐年限较短,后两种防腐层见附图1,虽属环保型,但存在着底胶[3]层较薄,与钢管[1]表面、基膜[4]背面粘接剥离强度较低。
本实用新型的目的是提供一种钢质金属管道外冷缠底胶层较厚,防腐胶带厚度均匀,与钢管表面粘接强度较高的改性沥青底胶聚乙烯防腐胶带而成的防腐管。
本实用新型的实现:钢质金属管道外表面除锈后,涂刷一层防腐底漆,底漆干燥后冷缠绕改性沥青底胶聚乙烯防腐胶粘带。
本实用新型的具体结构由以下的实例及其附图给出。
图1是根据本实用新型提出的沥青基聚乙烯胶带防腐管,它包括钢质金属管道[1]、底漆[2]、底胶[3]、基膜[4]。

Claims (2)

1、沥青基聚乙烯胶带防腐管,该管道有钢质金属管道[1],防腐底漆[2],改性沥青底胶[3],聚乙烯基膜[4],其特征是形状是直管状,厚度均匀一致,外表面聚乙烯基膜[4]之间有搭接。
2、根据权力要求1所述的沥青基聚乙烯胶带防腐管,其特征是改性沥青底胶[3]是黑褐色粘稠状固体。
