摘要

以邻苯二甲酸氢钾为添加剂

通过差示扫描量热分析

广角X-射线衍射分析

扫描电镜和电子万能实验机研究了其不同含量对聚氯乙烯(PVC)的晶体结构、微观形态和力学性能的影响.研究结果表明:当邻苯二甲酸氢钾的含量为3 w.t.%时

PVC的结晶度和晶粒尺寸增大

材料微观上形成了“三维网络”结构

使其宏观机械性能较纯PVC增大;但随着邻苯二甲酸氢钾含量的继续增大

PVC的结晶度和晶粒尺寸降低

微观上无网络结构生成而是形成了多孔的结构

并且孔径和孔的平面密度随着邻苯二甲酸氢钾的增多而增大

导致孔穴间基体厚度降低

不利于应力传递

使材料的力学性能显著降低.

Abstract

The influences of the content of potassium hydrogen phthalate on crystal structure

micromorphology and mechanical properties of polyvinyl chloride(PVC)are studied by differential scanning calorimetry

wide angle X-ray diffraction

scanning electron microscope and electron versatile tester.The analysis results indicate that compared with pure PVC

the crystallinity and crystallite size are increased when the content of potassium hydrogen phthalate is 3w.t.%

and a three dimension network is formed when PVC mechanical properties is increased.But with the further increasement of potassium hydrogen phthalate loading

the crystallinity and crystallite size are decreased and a hole like micromorphology is formed

and the hole diameter and its density on a plane are increased

so the thickness of PVC matrix among the holes is decreased and the transfer of stress is hampered

leading to the decline of PVC mechanical properties.
