Description

一种碳纳米管基聚合物共混彩色电缆料及其制备方法
技术领域
本发明涉及电缆材料领域，特别是一种碳纳米管基聚合物共混彩色电缆料及其制备方法。
背景技术
现有彩色软聚氯乙烯电缆料的通常做法是添加常规物质外，还需要添加各种色粉或色母粒做成彩色产品。多数情况下PVC产品会因为塑化不良、受潮等原因需进行二次加工，而彩色产品二次造粒过程会因少量聚氯乙烯分解而使新制得的彩色电缆料产生变色现象，使得变色的电缆料因颜色与原来不一致而不能再次使用，因此彩色PVC电缆料不能进行二次加工为原产品，使得需要额外使用新料制造彩色软聚氯乙烯电缆料，成本高。
本发明希望通过多聚氯乙烯电缆料进行改性，通过增强电缆料的稳定性，减少返工或者二次加工的次数，降低生产成本。碳纳米管是目前可制备出的具有最高比强度的材料。若将以其他工程材料为基体与碳纳米管制成复合材料，可使复合材料表现出良好的强度、弹性、抗疲劳性及各向同性，给复合材料的性能带来极大的改善。本发明将碳纳米管制成碳纳米管基聚合物、HDPE等聚合物与聚氯乙烯共混，制成改性聚氯乙烯电缆料，配合助剂的添加，增强了材料的热稳定性，耐磨性，延长了使用寿命，降低了生产成本。

本发明所述一种碳纳米管基聚合物共混彩色电缆料，由以下具体步骤制成：
(1)将4-联苯基丙烯酸酯、偶氮二异丁酸二甲酯、硅烷偶联剂A-172混合，放在80℃-90℃的水浴中边搅拌边加热，直到具有一定粘性时停止加热，冷却至室温，加入碳纳米管、氢氧化镁，搅拌均匀，然后控制温度在55℃-65℃，保持3-4小时，然后继续升温至90℃-100℃，保温100-120分钟得到碳纳米管聚合物母料A；
(2)将聚氯乙烯树脂、HDPE加热至熔融，然后加入除助剂之外的其余剩余成分混合均匀，搅拌10-15分钟，送入双螺杆挤出机上挤出造粒，得到B料；
(3)将A料、B料、助剂加入到高混机中，温度控制位120℃-130℃混合5-7分钟，然后通过双螺杆挤出机造粒，冷却干燥即得本发明电缆料。
