Description

一种耐加热的多层管
技术领域
本发明涉及一种多层管，特别是涉及一种耐加热的多层管。
背景技术
多层管多数由不同的材质构成不同的内层，从而具有不同的性能。塑料管在使用期间，塑料管的耐热性能对塑料管的使用时间有不可或缺的决定作用。在一些需要传送高温加热试剂或水的过程中，如果塑料管的耐热性能较差，则在长时间接触高温后，塑料管会发生形变和扭曲等现象，这些都制约着复合塑料管的使用和推广，如何将不同的塑料材质进行复合从而具备良好的耐热性，是一个较为复杂的问题。
发明内容
要解决的技术问题：常规的多层管材耐加热性能差的问题。
技术方案：本发明公开了一种耐加热的多层管，耐加热的多层管共三层，最外层为厚度2.2mm～2.5mm的聚苯乙烯树脂层、中间层为厚度1.3mm～1.7mm的呋喃树脂层、最内层为厚度2.6mm～3.0mm的聚砜树脂层。多层管中聚苯乙烯树脂层的厚度优选为2.2mm。多层管中呋喃树脂层的厚度优选为1.3mm。多层管中聚砜树脂层厚度优选为2.6mm。多层管中最内层的直径优选为10cm～15cm。多层管是通过每层塑材在加热情况下用模具熔合、冷却后得到的多层结构。  
有益效果：制备的多层管具有优良的耐加热特性，得到的多层管在温度为200至250℃下加热200h后，多层管没有发生变形或扭曲的现象，具有良好的耐热性能。
附图说明
图1为多层管的剖面示意图，1为聚苯乙烯树脂层、2为呋喃树脂层、3为聚砜树脂层。
具体实施方式
