技术领域
本发明涉及电子材料领域，具体是指一种电缆护套管的配方及其制备方法。
背景技术
随着城市化进程的逐步加快，城市规划越来越趋于现代化。在城市建设过程中，电缆入地成为了最低的建设要求。同时，在城市改造过程中，也需要将架设在空中的各种电缆入地。电缆入地目前往往会采用非开挖技术进行施工，这种施工方法具有不影响交通、对地层结构破坏小，周期短等优点，同时适用于，采用非开挖施工方法，对于电缆的要求高，具有表现为：电缆需要具有强度高、刚性韧性好等，另外，由于电缆本身的特点，还需要具有具有高阻燃性的特点，以防电路短路等造成火灾，引起安全事故。对于野外的电缆，也同样具有上述要求。电缆要达到上述要求，对其护套管也就具有同样的要求，因为护套管位于电缆的最外层。目前常见的电缆护套管，大都是主要采用聚乙烯、聚丙烯、聚氯乙烯等高分子材料，并加入了一定的添加剂，以改善其相关性能。但是，目前的这些电缆护套管，在强度、刚性任性以及阻燃性方面，仍然不理想，或者仅仅在某一方面的性能上面有一定的改进，存在很大的进一步改进的空间。
