Abstract

本发明一种阻燃型复合管材，具有无规共聚聚丙烯管体，在无规共聚聚丙烯管体外表面设置有一层阻燃层；所述阻燃层厚度为5-8mm；本发明将PP-R（无规共聚聚丙烯）管材做成两层复合结构，表层使用阻燃层材料制作，里层使用PP-R（无规共聚聚丙烯）层，由于表层使用阻燃层，其管材的氧指数达24%-25%；本发明加工简单，阻燃性强，造价低，符合国家安全使用标准。

Description

一种阻燃型复合管材
技术领域
本发明涉及给水管材，尤其是一种阻燃型复合管材。
背景技术
目前管材的类型、规格相当繁多，一般有金属管材、非金属管材及复合管材，根据使用要求，选择所需管材。现在家庭装修的给、排水管90%以上都使用PP-R（无规共聚聚丙烯）管材，但PP-R又是一种易燃烧性材料，其氧指数仅为17%-18%，燃烧后成炭率很低，燃烧时像蜡烛一样产生熔滴，而且这些熔滴又扩散继续燃烧，这对民用建筑的防火消防是一重大的安全隐患。
发明内容
本发明的目的就是对以上缺点进行改进，提供氧指数较高不易燃烧，使用寿命长，造价低的一种阻燃型复合管材。
本发明的具体方案是：一种阻燃型复合管材，具有无规共聚聚丙烯管体，其特征在于：在无规共聚聚丙烯管体外表面设置有一层阻燃层。
所述一种阻燃型复合管材，其特征在于：所述阻燃层厚度为5-8mm。
本发明将PP-R（无规共聚聚丙烯）管材做成两层复合结构，表层使用阻燃层材料制作，里层使用PP-R（无规共聚聚丙烯）层，由于表层使用阻燃层，其管材的氧指数达24%-25%。本发明加工简单，阻燃性强，造价低，符合国家安全使用标准。
附图说明
图1是本发明的主视图；
图2是图1的A—A剖视图。 
图中，1-无规共聚聚丙烯管体，2-阻燃层。
具体实施方式
参见1-2，本发明一种阻燃型复合管材，具有无规共聚聚丙烯层管体1，在无规共聚聚丙烯管体1外表面复合有一层阻燃层2；所述阻燃层2厚度为5-8mm。

Claims (2)

1.一种阻燃型复合管材，具有无规共聚聚丙烯管体，其特征在于：在无规共聚聚丙烯管体外表面复合有一层阻燃层。
2.根据权利要求1所述一种阻燃型复合管材，其特征在于：所述阻燃层厚度为5-8mm。
