Description

一种静音排水管
技术领域
本发明涉及一种排水管，尤其涉及一种静音排水管。
背景技术
目前聚氯乙烯排水管因其具有价格便宜、使用方便、使用寿命长的特点而被广泛，尤其是在家庭排水设施中更是得到广泛的应用，但早先的聚氯乙烯排水管都是单壁结构，在使用时，因排水会产生很大的噪音，从而对室内环境产生影响，现有也有多层式静音排水管排水管，其从内而外分成内聚氯乙烯层、吸音芯层和外聚氯乙烯层；但其现有的隔音效果并不理想。
发明内容
   针对上述缺点，本发明的目的在于提供一种具有良好隔音效果的静音排水管。
本发明的技术内容为：一种静音排水管，其从内而外分成内聚氯乙烯层、吸音芯层和外聚氯乙烯层；其特征在于吸音芯层包括如下重量百分比的组分：
聚氯乙烯                        50～60
热塑性橡胶(TPE)                  20～30
乙烯-醋酸乙烯共聚物(EVA)            10～20
二甲酸二辛酯                          3～5
石蜡                               1～5 
稀土稳定剂                            1～3 
其中热塑性橡胶(TPE)的细度为80～100目，EVA的细度为100～150目，VAE中的醋酸乙烯含量为50～70重量％。
在上述静音排水管中，内聚氯乙烯层和外聚氯乙烯层为常规的生产聚氯乙烯管的技术。
本发明通过常规的双机共挤的技术制备。
本发明与现有技术相比所具有的优点是：本发明吸音芯层中的弹性体热塑性橡胶(TPE)与乙烯-醋酸乙烯共聚物(EVA)能起到很好的隔音与吸音效果，故本发明具有良好的隔音效果。
附图说明
   图1为本发明的结构示意图。
具体实施方式
如图1所示，一种静音排水管，其从内而外分成内聚氯乙烯层1、吸音芯层2和外聚氯乙烯层3；其特征在于吸音芯层包括如下重量百分比的组分：
聚氯乙烯                        50
热塑性橡胶(TPE)                 25
乙烯-醋酸乙烯共聚物(EVA)          15
二甲酸二辛酯                        3
石蜡                             1 
稀土稳定剂                         1 
其中热塑性橡胶(TPE)的细度为85目，EVA的细度为120目，VAE中的醋酸乙烯含量为60重量％；稀土稳定剂为广东东莞炜林纳功能材料有限公司生产的X-1稀土稳定剂。
