Abstract

本发明公开一种阻燃材料，所述阻燃材料包含一种聚合物和至少两种高纯度细沉淀Al(OH)3阻燃填料，其特征在于，一种填料在分离时具有另一种填料至少130％的比表面积；例如，第一Al(OH)3填料在分离时具有4至8m2/g的比表面积(理想地在6至8m2/g之间)，第二Al(OH)3填料在分离时具有8至14m2/g的比表面积(理想地在10至12m2/g之间)。

Description

阻燃材料和具有包含该阻燃材料的线缆外皮的线缆
本发明涉及阻燃材料和包含阻燃材料的线缆外皮。
已知高纯度细沉淀氢氧化铝Al(OH)3作为线缆外皮的阻燃填料的应用。另外，此类填料可以购得，包括作为Martinal
Figure BPA00001403385500011
OL-111/LE、OL-107/LE、OL-104/LE、OL-104/A和OL-107/A从AlbemarleCorporation

购得的那些填料。在以上这些填料中，OL-104/A和OL-107/A经过乙烯基硅烷处理。
根据本发明，提供了一种阻燃材料，所述阻燃材料包含一种聚合物和至少两种高纯度细沉淀Al(OH)3阻燃填料，其特征在于，一种填料在分离时具有另一种填料至少130％的比表面积；例如，第一Al(OH)3填料在分离时具有4至8m2/g的比表面积(理想地在6至8m2/g之间)而第二Al(OH)3填料在分离时具有8至14m2/g的比表面积(理想地在10至12m2/g之间)。
不希望受任何理论约束，相信填料比表面积越高，与聚合物链的物理相互作用的机会越大(反之亦然)，这导致积极的分散和优良的物理性质。然而，对于非常高的比表面积-为优良的阻燃性所需，与聚合物链的物理相互作用变得太强，这降低弹性和冷弯曲性能。发明人认识到，通过使用包含具有不同比表面积的填料的组合的材料，可产生不可预期的协同作用，从而保持优良的阻燃性水平(例如，符合ULVW-1燃烧性试验)，同时还保持优良的物理性能(例如，强度大于10Mpa，伸长接近200％，等级领先的冷弯曲性能(class leading coldbending performance))。
第二Al(OH)3填料在分离时可具有第一Al(OH)3填料至少150％的比表面积。另外，第一Al(OH)3填料可经受乙烯基-硅烷处理，并且，其中第二Al(OH)3填料不经受如此处理。这些措施似乎增强前述协同作用。
第一填料与第二填料之比优选在1∶1.27和1∶1.67之间，更优选在1∶1.37和1∶1.57之间，理想地为1∶1.47。
材料中第一填料和第二填料的组合含量优选在50％和70％之间，更优选在55％和65％之间，理想地为60％。
第一Al(OH)3填料优选为上述Martinal 107A。
第二Al(OH)3填料优选为上述Martinal 111LE。
现在仅以例示的方式参考附图来描述本发明的实施方案。
根据本发明，提供了一种线缆，所述线缆包括具有阻燃材料的线缆外皮，所述阻燃材料包含30％低密度聚乙烯共聚物、24％经乙烯基-硅烷处理的Martinal OL-107A和36％未处理的Martinal OL-111/LE。诸如抗氧化剂和着色剂的常规添加剂组成其余部分。
上述材料可通过如下方法制备：将粒状聚合物加热到120至140℃之间，随后，使用混合机(常用混合设备)使经塑炼的聚合物与第一Martinal OL-107A混合，然后与Martinal OL-111/LE混合。
