Description
技术领域
本发明属于电缆制造技术领域,具体涉及一种双层抗氧化PVC电缆。
背景技术
电缆的使用广泛,电缆在生产过程中,通常会在导电芯的外层包覆一层绝缘层,该绝缘层起到保护内部导电芯和绝缘的作用。但由于电缆在使用过程中,绝缘层会长期暴露在空气中以及其他的氧化环境中,绝缘层易老化,降低了电缆的使用寿命。在现有技术中,通常是在绝缘层中加入某些抗氧化剂,以延缓老化,但仅在绝缘层中添加抗氧化剂,电缆的抗氧化性扔较差,不能很好的满足使用要求。
发明内容
本发明的目的在于:解决上述现有技术中的不足,提供一种双层抗氧化电缆。
为了实现上述目的,本发明采用的技术方案为:一种双层抗氧化PVC电缆,包括内层的绝缘层和外层的抗氧化层,所述的绝缘层由以下原料制得,按重量份数计为:PVC树脂粉40-60份,轻钙15-25份,重钙10-20份,DOP油15-25份,氯化石蜡油5-10份,环氧大豆油1-3份,安定剂2-3份,硬脂酸0.5-1份,聚乙烯蜡0.3-1份,颜料0.2-0.5份;所述的抗氧化层由以下原料制得,按重量份数计为:PVC树脂粉40-60份,DOP油20-30份,环氧大豆油1-3份,安定剂1-2份,抗氧化剂0.05-0.2份。
进一步的,所述的绝缘层的原料还包括阻燃剂,所述阻燃剂按重量分数计为0.5-1.5份,该阻燃剂为三氧化二锑。
制备该双层抗氧化PVC电缆的方法,包括以下步骤,将绝缘层的原料加入PVC造粒机中,搅拌,挤出,冷却,切粒,得到绝缘层胶粒;将抗氧化层的原料加入PVC造粒机中,搅拌,挤出,冷却,切粒,得到抗氧化层胶粒;将上述制得的绝缘层胶粒投入到挤出机的主料斗中,绝缘层胶粒从主料斗进入到料筒中,在主料筒中依次经过加料段、熔融段、均匀化段和输送段,熔融后流向机头第一流道,将上述制得的抗氧化胶粒投入到挤出机的辅料斗中,抗氧化层胶粒在辅料筒中熔融后,流向机头的第二流道,在机头处挤出双层PVC电缆,第一流道的熔融物挤出后为内层,第二流道的熔融物挤出后为外层。
进一步的,所述的加料段的温度为121-148℃,所述的熔融段的温度为143-153℃,所述的均匀化段的温度为165-170℃,所述的输送段的温度为160-200℃,所述的挤出机的主料斗和副料斗的温度为70℃。
进一步的,所述的挤出机包括挤出机头、第一流道、第二流道、主料筒、主料斗、辅料筒和辅料斗,所述的主料斗连接在所述的主料筒一端,所述的挤出机头连接在所述的主料筒的另一端,所述的第一流道设置在所述的挤出机头内,所述的辅料斗与所述的辅料筒的连接,所述第二流道设置在所述的辅料筒的另一端,该第二流道设置在所述的挤出机头外壁。
由于采用了上述技术方案,本发明的有益效果是:本发明采用双层PVC,在绝缘层外包覆一层抗氧化的PVC层,使抗氧化的PVC单独作为一层,提高了电缆的抗氧化性;在制备本发明的电缆时采用一台挤出机,绝缘层和抗氧化层的熔融料提前在机头内混合,在高温和压力的作用下,绝缘层和抗氧化层紧密融合,同时在导电芯上挤出两层紧密结合的PVC层,与现有技术中的采用两台挤出机相比,节约了生产成本和运营成本。
