氯化聚氯乙烯导热管的研制

本文研究了适用于单螺杆挤出的氯化聚氯乙烯(CPVC)导热管的配方和工艺条件。实验结果表明:几种稳定剂并用作为CPVC的稳定体系,效果较好;ACR对CPVC复合物的胶凝化有明显的促进作用,能有效地改善CPVC的加工性能;石墨粉能显著地提高CPVC的导热性能,但会因此降低冲击性能。因此使用石墨粉时必须添加抗冲改性剂以改善冲击性能,同时兼顾其他力学性能和使用要求。

The Development of Thermal Conductivity CPVC Pipe

In this paper, the formulation and processing technology for CPVC thermal conductivity pipe produced by single screw extruder were investigated. It was revealed that the use of several stabilizers had a good result :the gelation and processing characteristic of CPVC could be improved obviously by the use of ACR, and the thermal conductivity by powdered graphite filler with a little decrease of the impact strength of CPVC. So it is necessary to use impact modifier to improve the impact resistance,mechanical and other property essential to application.
