技术领域
本发明涉及电线电缆领域,具体指一种电缆用阻水型发泡填充条及其制备方法。
背景技术
在电缆生产过程中,为保证电缆的圆整性,同时避免芯线之间的相互磨擦,需要在芯线之间添加填充材料,现有的阻水型电缆一般采用阻水纱进行填充,电缆外观圆整度不好,并且造价高;采用普通的填充条填充,填充条容易进水,无法达到阻水效果,影响阻水型电缆的正常使用。因此,阻水型发泡填充条的生产制造对于阻水型电缆显得尤为重要。上述不足仍有值得改进的地方。
发明内容
本发明所要解决的技术问题是针对现有技术的不足,提供一种电缆用阻水型发泡填充条,使电缆产品的外圆圆整度和平整度好,造价低,同时使电缆具有良好的阻水效果。
为了解决上述现有技术中存在的缺陷,本发明还提供一种电缆用阻水型发泡填充条及其制备方法,使其生产的电缆填充条具有良好的阻水性能、导热性能,减小填充料对电缆传输能力的影响,能够有效防止水沿填充空隙处入侵,防止电缆水树的产生,延长了电缆护套的使用寿命。
为了实现上述目的,本发明的所述的一种电缆用阻水型发泡填充条,它主要由下述组分及重量份的物料制成:
交联聚乙烯:50~70份;
乙烯醋酸乙烯:40~50份;
高吸水树脂:10~20份;
增塑剂:15~30份;
炭墨:2~4 份;
发泡剂:1~2 份。
所述的交联聚乙烯的料度为200目~300目。
所述的增塑剂为石蜡和白油以重量比为0.5~5:1的混合物。
以上所述的一种电缆阻水型发泡填充条的制备方法,其工艺步骤如下:
A、将交联聚乙烯、烯醋酸乙烯、高吸水树脂、增塑剂、炭墨、发泡剂按配比加入混合机中混合10~15 分钟,投入塑料挤塑机经模具挤出填充条。
B、将步聚A 中所得到的填充条经挤出机在120~200℃挤出并发泡成型;
C、再将步骤B中所成型的填充条经50℃左右的水冷却即可。
有益效果:本发明所述的一种电缆用阻水型发泡填充条及其制备方法,根据目前阻水型电缆的要求设计阻水型填充条,通过加入发泡剂产生发泡孔,使高吸水树脂在遇水的情况下,能够有溶胀的空间,使填充条具有纵向和径向阻水的效果,有效防止电缆水树的产生,保证电缆的安全运行。
