电铲用高耐磨电缆及其应用
技术领域
本发明涉及一种电缆，具体涉及一种电铲用高耐磨电缆及其应用。
背景技术
电铲又称绳铲、钢缆铲，即机械式电动挖掘机是利用齿轮、链条、钢索滑轮组等传动件传递动力的单斗挖掘机，在矿山出矿过程中广泛应用。
电铲在运转过程中，电缆往往被来回拖拽造成磨损严重，大大缩短了电缆的使用寿命，并且，存在漏电的安全隐患。
发明内容
针对现有技术的不足，本发明的目的是提供一种电铲用高耐磨电缆，解决电铲运转过程中造成的磨损严重的问题，延长电缆的使用寿命，防止漏电安全事故的发生；本发明同时提供其应用。
本发明所述的电铲用高耐磨电缆，包括导体芯和保护层，保护层由如下重量份数的原料制成：
其中：
所述的改性聚氨酯为有机硅改性聚氨酯。
所述的聚醚二元醇的分子量为1000-2000。
所述的催化剂为二月桂酸二丁基锡、2,4,6-三(二甲胺基甲基)苯酚和五甲基二亚乙基三胺，三者之间的质量比为0.5-1.5：1-2.5：0.5-2。
所述的水玻璃为波美度为20-60度的硅酸钾水溶液。
所述的抗氧剂为抗氧剂1010。
所述的保护层采用如下方法制备：
首先，将改性聚氨酯、三元乙丙橡胶、环氧树脂和聚醚二元醇装入混合釜中搅拌，搅拌转速为1000-2000r/min，然后将其他原料加入，室温下搅拌30分钟。
所述电缆在制备时，将制备好的保护层材料在20-30分钟内涂覆在导体芯上，涂层厚度为5毫米。
使用时，与回头轮配合使用，能够进一步减少磨损，延长其使用寿命。
与现有技术相比，本发明的有益效果如下：
(1)本发明加入水玻璃和高岭土，利用钾水玻璃在高岭土微球上的原位晶化来提高电缆保护层的强度，增强电缆的耐磨性，同样的运转强度下，其使用寿命较普通电缆长2倍多。
