Abstract

本实用新型涉及一种聚丙烯管材，包括聚丙烯内层管，聚丙烯外层管、聚丙烯中间层和保护层，所述聚丙烯内层管与聚丙烯外层管之间设有聚丙烯中间层，其中聚丙烯内层管和聚丙烯外层管为纯普通聚丙烯材料，聚丙烯中间层为增强聚丙烯复合材料。本实用新型有益效果为：采用增强聚丙烯复合材料，可以显著地提高聚丙烯管道的刚性，环刚度为同规格的普通聚丙烯管道的两倍以上。

Description

一种聚丙烯管材
技术领域
本实用新型涉及一种聚丙烯管材。
背景技术
聚丙烯管道广泛应用于非压力管道系列，如供水、燃气、排污及通信电缆的保护套等领域，由于普通的聚丙烯材料弹性模量一般只有800MPa左右，在应用于非压力管道系统当管道深埋时，由于其上的土层的重量增加，其刚性就显得不足；当管道所处的施工环境恶劣时，经常会发生管道表面刮伤的现象，导致管道发生应力开裂、破损。
实用新型内容
本实用新型的目的是提供一种聚丙烯管材，以克服当管道深埋时，由于其上的土层的重量增加，其刚性就显得不足；当管道所处的施工环境恶劣时，经常会发生管道表面刮伤的现象，导致管道发生应力开裂、破损的不足。
本实用新型的目的是通过以下技术方案来实现：
一种聚丙烯管材，包括聚丙烯内层管，聚丙烯外层管、聚丙烯中间层和保护层，所述聚丙烯内层管与聚丙烯外层管之间设有聚丙烯中间层，其中聚丙烯内层管和聚丙烯外层管为纯普通的聚丙烯材料，聚丙烯中间层为增强聚丙烯复合材料。
本实用新型的有益效果为：采用增强聚丙烯复合材料，可以显著地提高聚丙烯管道的刚性，环刚度为同规格的普通聚丙烯管道的两倍以上。
附图说明
下面根据附图对本实用新型作进一步详细说明。
图1是本实用新型实施例所述的一种聚丙烯管材的横截面结构示意图；
图2是本实用新型实施例所述的一种聚丙烯管材的立体结构示意图。
图中：
1、聚丙烯内层管；2、聚丙烯外层管；3、聚丙烯中间层。
具体实施方式
如图1-2所示，本实用新型实施例所述的一种聚丙烯管材，包括聚丙烯内层管1，聚丙烯外层管2和聚丙烯中间层3，所述聚丙烯内层管1与聚丙烯外层管2之间设有聚丙烯中间层3，其中聚丙烯内层管1和聚丙烯外层管2为纯普通聚丙烯材料，聚丙烯中间层3为增强聚丙烯复合材料。
