Description

无卤低烟防火电缆料组合物及其制备方法
技术领域
本发明涉及一种无卤低烟防火电缆料组合物及其制备方法，属于电缆制造材料技术领域。
背景技术
随着社会的进步和科学技术的飞速发展，PVC内在的弱点(燃烧时释放的大量烟雾，严重的腐蚀性气体和有毒气体)益发明显，低烟无卤作为一种不含有毒元素的材料得到广泛的应用。在地铁、高层建筑、商场、剧院、发电站、化学工厂、城市广场及其他公用事业等对电缆阻燃特性要求高的场合，都需要采用低烟无卤阻燃电缆。但是在现有技术中，低烟无卤电缆料普遍存在阻燃性较差、力学性能不强、抑烟效果较差等问题。
发明内容
针对现有技术中的缺陷，本发明的目的是提供一种无卤低烟防火电缆料组合物及其制备方法。
本发明是通过以下技术方案实现的：
第一方面，本发明提供了一种无卤低烟防火电缆料组合物，其包括按重量份数计的如下组分：
若EVA树脂用量高于40份，会压缩添加剂份数，导致添加剂添加不足，产品性能不能达标；若EVA树脂用量低于25份，会导致塑化性能不足。
阻燃剂用量高于48份，会导致与改性阻燃剂协同效果变差无法达到预期性能；若低于30份，会导致产品阻燃性能不达标。
作为优选方案，所述阻燃剂包括氢氧化铝和氢氧化镁中的一种或两种。
作为优选方案，所述改性阻燃剂包括粒径在0.2～0.5um之间氢氧化铝，粒径大小决定氢氧化铝的性能，粒径越小性能越好，小粒径氢氧化铝在加工时增加了与EVA的接触面，加工出来的成品性能增加。
改性阻燃剂阻燃性能较普通阻燃剂更好，与普通阻燃剂搭配使用主要是为了在达到性能要求的基础上并综合考虑到成本控制。
作为优选方案，所述助剂包括有机硅类润滑剂、偶联剂、硼酸锌中的至少一种。
助剂若低于0.5份，会导致产品机械性能差，难以加工，份数在3份以内基本能达到加工要求。
第二方面，本发明还提供了一种如前述的无卤低烟防火电缆料料组合物的制备方法，其包括如下步骤：
将EVA树脂、阻燃剂和助剂混合均匀后，进行挤出造粒，挤出过程中，控制8个控温区的温度分别为：1-2区温度为100～120℃，3-4区温度为120～140℃，5-6区温度为130～150℃，7-8区温度为140～160℃。
与现有技术相比，本发明具有如下的有益效果：
本发明制备的电缆料的断裂伸长率为180～230％、拉伸强度为11～13MPa、氧指数为34～36。
具体实施方式
下面结合具体实施例对本发明进行详细说明。以下实施例将有助于本领域的技术人员进一步理解本发明，但不以任何形式限制本发明。应当指出的是，对本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进。这些都属于本发明的保护范围。
