摘要:

通过高温热解聚合物方法将碳纳米涂层沉积到滑石粉的表面,并将其与炭黑协同填充到聚氯乙烯/丙烯腈-丁二烯-苯乙烯共聚物(PVC/ABS)复合材料中,研究了滑石粉与炭黑含量对复合材料电学性能、力学性能、热稳定性与阻燃性能的影响。结果表明,添加3份滑石粉时,炭黑的逾渗值仅为3份,在此添加量下复合材料的拉伸强度提高了14.4 %,原因为滑石粉与炭黑在基体内构成了网络结构,滑石粉作为节点在基体内随机位置、随机方向分布,而炭黑可作为连接各个节点的通道。

Abstract:

A carbon nano coating was deposited on the surface of talc powder using a high-temperature pyrolysis polymer method and then was incorporated into PVC/ABS composite with carbon black. The effects of contents of talc powder and carbon black on the electrical properties, mechanical performance, thermal stability, and flame retardancy of the composites were investigated. The experimental results indicated that when 3 parts of talc powder was added into the composites, the percolation value of carbon black was only 3 parts. The tensile strength increased by 14.4 % for the composite with this addition amount. This can be explained by the fact that talc powder and carbon black can form a network structure in the matrix, in which talc powder is distributed in random positions and directions as nodes and carbon black acts as a channel to connect the nodes with each other.
