摘要：运用热压成型法制备高填充含量下的EVA/MgO复合胶膜。探讨MgO含量对复合胶膜导热绝缘性能、黏结性能和交联度的影响,偶联剂量对胶膜粘结性能的影响以及温度对胶膜交联度的影响。用TGA测定胶膜热失重曲线,并采用扫描电镜(SEM)观察了胶膜中MgO的分散情况。结果表明:功能复合后的导热性能得到较大提高,绝缘性能未发生明显下降;胶膜黏结性能与交联度在10%体积含量填充下达到最大,且其热稳定有所提高。
The EVA/MgO composite film with high content of MgO was prepared by hot pressing molding methods. The effect of MgO content on the thermal conductivity, insulating property, adhesive property and crosslinking degree of the composite film was discussed. And the effect of coupling agent content on adhesive property of film, the temperature on the crosslinking degree film was also studied. The thermo-gravimetric curve of film was determined by TGA, and the dispersion of MgO in the film was observed by SEM. The results showed that the thermal conductivity of composite film got improved and its insulation performance didn＇ t distinctly drop. The adhesive properties and degree of crosslinking got the peak at 10 % content, and the thermal stability was improved.
