Description

一种PVC阻燃电缆护套料
技术领域
本发明涉及一种电缆护套料，尤其是一种PVC阻燃电缆护套料，属于电缆技术领域。
背景技术
电力电缆使用时一般都会在外层增加阻燃护套料，以防止电缆在积聚大量热量而发生火灾，而正是物料燃烧时产生的烟，这些烟不但产生大量的有毒物质，而且可以导致人窒息，这才是因火灾而死亡的主要因素，因此研究具有良好阻燃性能的电缆保护套是防止电力电缆火灾的重要课题。
发明内容
本发明的目的是针对上述现有技术的不足，提供一种PVC阻燃电缆护套料。本发明具有阻燃性能高，存贮存时间长，强度高，抗撕裂性能好，耐盐雾性好，外观光滑，不易焦烧，易加工的优点。
本发明的目的是通过以下技术方案实现的：一种PVC阻燃电缆护套料，其特征是，包括以下各组份按重量份制备而成：PVC树脂90-100份、氧化铝5-10份、氢氧化镁4-5份、硬脂酸1-2份、氧化锌4-5份、氧化镁3-5份、促进剂1-2份、润滑剂0.5-2份、半补强碳黑3-5份、癸二酸二辛酯20-25份、改性海泡石2-3份、助剂2-6份。
所述助剂是由下述重量份的原料组成的：天然橡胶30-40份、轻质碳酸钙5-8份、乙萘酚1-2份、八钼酸铵2-4份、松焦油2-3份、聚乙烯醇缩丁醛酯2-3份、二硬脂酸乙二酯1-2份、均苯四酸二酐1-2份、钨酸钠0.3-0.5份、硅烷偶联剂kh560 1-2份。
所述促进剂为促进剂M、促进剂TMTD、促进剂CZ。
所述润滑剂为硬脂酸钙、聚乙烯蜡。
一种PVC阻燃电缆护套料，其特征是，包括以下各组份按重量份制备而成：PVC树脂95-99份、氧化铝7-8份、氢氧化镁4-5份、硬脂酸1-2份、氧化锌4-5份、氧化镁3-5份、促进剂1-2份、润滑剂0.8-1.5份、半补强碳黑3-5份、癸二酸二辛酯22-24份、改性海泡石2-3份、助剂2-4份。
PVC树脂是一个极性非结晶性高聚物，分子之间有较强的作用力，是一个坚硬而脆的材料；抗冲击强度较低。氧化铝难溶于水的白色固体，无臭、无味、质极硬，易吸潮而不潮解（灼烧过的不吸湿）。
氢氧化镁是塑料、橡胶制品优良的阻燃剂。在环保方面作为烟道气脱硫剂，可代替烧碱和石灰作为含酸废水的中和剂。亦用作油品添加剂，起到防腐和脱硫作用。另外，还可用于电子行业、医药、砂糖的精制，作保温材料以及制造其他镁盐产品。
癸二酸二辛酯为耐寒性增塑剂，具有增塑效率高、挥发性低、既有优良的耐寒性，又有较好的耐热性、耐光性和电绝缘性。
天然橡胶一般为片状固体，相对密度0.94，折射率1.522，弹性膜量2～4MPa，130～140℃时软化，150～160℃粘软，200℃时开始降解。常温下有较高弹性，略有塑性，低温时结晶硬化。有较好的耐碱性，但不耐强酸。不溶于水、低级酮和醇类，在非极性溶剂如三氯甲烷、四氯化碳等中能溶胀。
本发明护套柔软性好，且具有优良的物理机械性能和阻燃性能，经久耐用，为耐紫外辐射电源线护套的开发奠定了原料基础，且符合UL和欧盟ROHS要求，环保完全，解决了阻燃性能、物理机械性能、环保性能等难以全面达到要求的技术难题，具有巨大的社会效益和经济效益。
