摘要

为了研究环氧增韧剂液态聚硫橡胶(PSR)对环氧树脂介电性能的影响

采用直接共混法制备了PSR/环氧树脂复合材料试样(PSR的质量分数分别为0%、5%、10%、15%和20%)

通过扫描电子显微镜和差示扫描量热法对试样的微观形貌和玻璃化转变温度进行分析

测试了试样的直流击穿场强、频域介电谱和表面电位衰减特性。测试结果表明:PSR的添加会导致环氧树脂玻璃化转变温度降低; 添加PSR能够有效提升环氧树脂的直流击穿场强; 环氧树脂介电常数和介质损耗随着PSR质量分数的增大先增大后减小; PSR会使环氧树脂的表面电位衰减速度减慢。通过等温表面电位衰减模型提取陷阱参数发现

添加PSR后

深、浅陷阱中心的深度增大

深陷阱电荷的密度随着PSR浓度的增大先减小后增大

除了PSR质量分数为20%外

其余含量PSR的添加均会导致浅陷阱电荷密度减小。基于电荷输运过程以及空间电荷击穿理论

认为陷阱深度的增大使陷阱捕获效应增强

导致碰撞电离和空间电荷的累积受到抑制

从而提高了直流击穿场强。

Abstract

PSR/epoxy composite samples(0%

10%

15% and 20% in mass fraction

respectively)are prepared by direct blending method to study the effects of epoxy toughener - liquid polysulfide rubber - on the dielectric properties of epoxy resin. The micro-morphology and glass transition temperature of the samples are analy-ed by SEM and DSC. The DC breakdown field strength

frequency domain dielectric spectrum and surface potential decay characteristics of the samples are tested. Results show that the glass transition temperature of epoxy resin decreases with addition of PSR

but the DC breakdown field strength of epoxy resin is effectively improved; the dielectric constant and dielectric loss first increase and then decrease with the increase of PSR concentration; and adding PSR slows down the surface potential decay rate of epoxy resin. It is found through extracting the trap parameters from isothermal surface potential decay model that with the addition of PSR

the depth of deep and shall
