Description

一种防水防尘电缆
技术领域
本发明涉及电缆技术领域，具体涉及一种防水防尘电缆。
背景技术
在电缆的使用过程中，如果电缆外的绝缘层及其他的防火层在发生毁损或老化而致电缆中心的导体外漏，会造成安全隐患，在电缆中心的导体被水浸时，更可能会对使用人员或其他人员造成无法挽回的伤害，电缆的安全性极其重要，上述的问题应当在电缆的设计和生产使用中予以防范并解决。
目前，电缆主要通过聚乙烯防水层或阻水导体等来防止电缆长期使用过程中产生潮气、损坏电缆，但这些防水方式并不能完全地隔绝水汽对电缆的损坏。
发明内容
本发明为了克服现有技术中存在的上述缺陷，提供了一种防水防尘电缆，能多层防水，并具有自清洁功能。
为解决上述问题，本发明提出的一种防水防尘电缆，包括多条导体及包裹在导线外的绝缘层、填充结构、绕包层、屏蔽层和防护层，所述绝缘导线间加入填充结构后，依次包裹绕包层、屏蔽层和防护层；所述防水防尘电缆还包括防潮层和疏水层；所述防潮层设置在屏蔽层和防护层之间，所述疏水层设置在防护层的外层，所述疏水层材料配方按质量份数包括以下组分：
聚烯烃树脂55-70份、聚二甲基硅氧烷15-20份、纳米氧化硅 5-10份、纳米二氧化钛5-10份、蛭石5-8份、硅烷偶联剂3-5份、碳酸钙3-8份、氯化石蜡6-9份、邻苯二甲酸二辛酯1-2份、β-(3， 5-二叔丁基-4-羟基苯基)丙酸十八碳醇酯0.5-1份。
优选地，所述保护层材料按质量份数包括以下组分：聚烯烃树脂60份、聚二甲基硅氧烷18份、纳米氧化硅8份、纳米二氧化钛8 份、蛭石6份、硅烷偶联剂4份、碳酸钙5份、氯化石蜡7份、邻苯二甲酸二辛酯1.5份、β-(3，5-二叔丁基-4-羟基苯基)丙酸十八碳醇酯1份。
优选地，所述所述硅烷偶联剂为γ-氨丙基三乙氧基硅烷、γ-缩水甘油醚氧丙基三甲氧基硅烷或γ-甲基丙烯酰氧基丙基三甲氧基硅烷中的一种。
优选地，所述聚烯烃树脂包括聚氯乙烯、聚乙烯、聚丙烯、聚苯乙烯中的一种或多种。
优选地，所述防潮层采用填充热熔胶材料进行防水。
本法明提供一种防水防尘电缆的制备方法，包括以下步骤：
步骤一、按疏水层配方比例称取各组分原料，将称取的组分原料混合，以高速搅拌30-40min，得到混合料；
步骤二、将混合料进行筛选、挤出、造粒得到颗粒料；
步骤三、将颗粒料加入基础成型机中进行成型、定径、牵引、切割后，得到疏水层；
步骤四、将疏水层用于所述电缆防护层的外层，即得防水防尘电缆。
本发明中，纳米氧化硅，粒径为20-40nm，购于上海水田材料科技有限责任公司；纳米二氧化钛，粒径为15-30nm，锐钛矿型，购于上海尼原实业有限公司。
本发明与现有技术方案相比具有以下有益效果和优点：
1、以聚二甲基硅氧烷、纳米氧化硅、纳米二氧化钛构造荷叶仿生结构，通过硅烷偶联剂表面改性与聚烯烃树脂及其它组分制备电缆疏水层，使得电缆具有荷叶超疏水自清洁特性，使水不能进入电缆内部，仅在电缆外层形成水珠，同时灰尘会更好地贴附于水滴表面，随着水滴滚落，达到防水防尘的效果。
2、所述电缆设有防潮层，在疏水层防水防尘的同时，无法阻隔水蒸气的侵入，防潮层吸收水蒸气，使得电缆具有双层防水的效果。
