Description

改进型承压式复合排水管及其制备方法
技术领域
本发明属于管材技术领域，特别是涉及一种改进型承压式复合排水管及其制备方法。
背景技术
现有技术的排水管一般是采用高密度聚乙烯材料在热熔状态下缠绕成型，自然风冷后，冷态脱模制备而成。由于其具有寿命长、质量稳定、密闭性好等优势。随着我国经济的高速发展，我国埋地管道的设计要求中口径不断增大，随着内径增大，这就需要更大的埋地深度，这就对管材提出了更高的环刚度和抗变形能力的要求，避免使用过程中出现压溃等现象。
另一方面，现有的排水管一般不能排水承压，不适用于山区排水，突遇暴雨天气排水量增大时，普通排水管容易开裂。
而且，在管体内壁粘接缝处容易累积污垢，不仅不方便清理，而且容易造成渗漏，影响排水管使用寿命。管道内需要定期进行清理工作，管道内漆黑一片，不利于清理工作的进行。
因此，如何解决上述现有技术存在的缺陷成为了该领域技术人员努力的方向。
发明内容
本发明的目的就是提供一种改进型承压式复合排水管，能完全解决上述现有技术的不足之处。
本发明的目的通过下述技术方案来实现：
一种改进型承压式复合排水管，包括管体，管体表面有螺旋形加强筋，所述管体包括内层和外层，在内层与外层之间有空隙，空隙中设有连接内层与外层的连接筋，该连接筋为沿空隙周向均匀设置，且沿管体长度方向呈螺旋状布置，所述管体内壁设有一层与管体颜色不同的塑胶层，管体左右两端的口径一致，相邻管体之间通过热熔直接对接连接，所述加强筋内为空腔，空腔内设置有波纹管。
作为优选，所述管体底部设有渗水孔。
作为优选，所述相邻管体连接处套接热缩套或电热熔带。

作为优选，所述管体的内层和外层内混合有聚丙烯材料。
一种上述改进型承压式复合排水管的制备方法，其特征在于：
按照以下重量份配料：聚烯烃50-60份，玄武岩纤维10-15份，聚丙烯5-10份，改性聚烯烃弹性体5-8份，改性滑石粉20-30份，将原料混合均匀后通过双螺杆挤出机熔融造粒，得到改性聚烯烃复合材料，挤出机料筒各段温度分别为：180℃，190℃，200℃，210℃，220℃，口模温度为：215℃；
其中，
玄武岩纤维的处理方法如下：在去离子水中加入0.1%非离子型表面活性剂配制成水乳液，将KH-550硅烷偶联剂溶于水中，配成0.5%-2.0%的溶液；将玄武岩纤维浸渍于上述溶液中2.5小时，取出后再100-120℃的温度下烘干30分钟；
改性聚烯烃弹性体制备方法如下：按照以下重量份备料，乙烯辛烯共聚物100份、苯乙烯3-6份、甲基丙烯酸缩水甘油酯3-6份和过氧化二异丙苯0.2-0.4份，按照上述配比称料混合后采用双螺杆挤出机，以反应挤出工艺制备改性聚烯烃弹性体，挤出机料筒各段温度分别为：160℃，170℃，180℃，190℃，190℃。
进一步，管体与塑胶层各自由一台挤出机挤出成型，一台挤出成型管体，另一台挤出成型塑胶层。
与现有技术相比，本发明的有益效果在于：
1.管体的内层与外层之间设有连接筋有效解决了现有技术中克拉管环刚度较差，容易变形的问题，且具有优秀的柔韧性，加强筋内设波纹管进一步提高克拉管的环刚度和抗变形能力；
2.管体内壁设置有塑胶层，塑胶层光滑平整，不仅有利于污水的通过，不易结垢，而且掩盖了管体上的粘接缝，从而避免了从粘接缝处的渗漏，整体提高了管体的密封性能；
3.塑胶层采用桔色或黄色，在光线的照射下，管内视线良好，有利于清理工作的进行；
4．管体底部设有渗水孔，可以将水渗入土壤，有效提高地下水位；
5.相邻管体通过热熔直接对接连接，不仅工艺简单，大幅度提高了工作效率，而且能承受一定的水压。

具体实施方式
下面结合具体实施例和附图对本发明作进一步的说明。
实施例一
如图1和图2所示，一种改进型承压式复合排水管，包括管体1，管体1表面有螺旋形加强筋2，所述管体1包括内层101和外层102，在内层101与外层102之间有空隙103，空隙103中设有连接内层101与外层102的瓦楞状连接筋104，该连接筋104为沿空隙103周向均匀设置，且沿管体1长度方向呈螺旋状布置。所述加强筋2内为空腔，空腔内设置有波纹管3，该波纹管3可以为塑料波纹管，也可以使金属波纹管。
所述管体1内壁设有一层与管体颜色不同的塑胶层4，该塑胶层4内壁光滑平整，不仅有利于污水的通过，不易累积污垢，而且掩盖了带状板材之间的粘接缝，从而避免了从粘接缝处的渗漏，提高了管体的密封性能。
所述管体1左右两端的口径一致，相邻管体1之间通过热熔直接对接连接，采用此连接方式，简化了工艺简单，大幅度提高了工作效率。而传统的管体连接方式是，将管体一端的内径加工成与另一端的外径相匹配，相邻管体通过端部插接的方式进行连接，不仅工艺复杂，而且耗时长。
一种上述改进型承压式复合排水管的制备方法，其特征在于：
按照以下重量份配料：聚烯烃50-60份，玄武岩纤维10-15份，聚丙烯5-10份，改性聚烯烃弹性体5-8份，改性滑石粉20-30份，将原料混合均匀后通过双螺杆挤出机熔融造粒，得到改性聚烯烃复合材料，挤出机料筒各段温度分别为：180℃，190℃，200℃，210℃，220℃，口模温度为：215℃。
其中，
玄武岩纤维的处理方法如下：在去离子水中加入0.1%非离子型表面活性剂配制成水乳液，将KH-550硅烷偶联剂溶于水中，配成0.5%-2.0%的溶液；将玄武岩纤维浸渍于上述溶液中2.5小时，取出后再100-120℃的温度下烘干30分钟。
改性聚烯烃弹性体制备方法如下：按照以下重量份备料，乙烯辛烯共聚物100份、苯乙烯3-6份、甲基丙烯酸缩水甘油酯3-6份和过氧化二异丙苯0.2-0.4份，按照上述配比称料混合后采用双螺杆挤出机，以反应挤出工艺制备改性聚烯烃弹性体，挤出机料筒各段温度分别为：160℃，170℃，180℃，190℃，190℃。
管体1与塑胶层4各自由一台挤出机挤出成型，一台挤出成型管体1，另一台挤出成型塑胶层4，在模具内复合双层结构，带状形式连续挤出，冷却定型，经缠绕成型为排水管。塑胶层4采用HDPE材料。
实施例二
如图1所示，本实施例与实施例一的不同之处在于，所述管体1底部设有渗水孔5，可以将水渗入土壤，有效的提高地下水位，而且该渗水孔5由管体1内壁向管体1外壁倾斜设置，可以避免管外泥沙进入到管体1内。
实施例三
本实施例与实施例一的不同之处在于，所述相邻管体连接处套接热缩套或电热熔带。这种连接方式，可以进一步增强连接处的强度，避免泄露。
实施例四
本实施例与实施例一的不同之处在于，所述管体1两端的内外径与法兰匹配，所述相邻管体1之间通过法兰连接。所述相邻管体1之间还可以通过法兰连接阀门。而传统排水管的内外径与法兰不匹配，因此，传统排水管上无法安装阀门。
实施例五
本实施例与实施例一的不同之处在于，所述塑胶层4的颜色为桔色或黄色，在进行井下管道清理作业时，不仅容易分辨管体位置，而且在光线的照射下，管内视线良好，有利于清理工作的进行。
实施例六
如图1所示，本实施例与实施例一的不同之处在于，所述管体1的内层101和外层102内混合有聚丙烯材料，有利于降低管体1重量轻，提高管体1弹性，相较于聚乙烯更耐磨，使用寿命更长。
实施例七
如图3所示，本实施例与实施例一的不同之处在于，所述管体1上还螺旋缠绕有辅助增强筋6，辅助增强筋6与螺旋形加强筋2平行设置。该辅助增强筋6截面为半圆形，其内设置空腔，且辅助增强筋6的截面尺寸小于螺旋形加强筋2的截面尺寸。辅助增强筋6的设置有利于进一步增强排水管的环刚度，减少产品输送时的断裂现象。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
