陶瓷化填料对三元乙丙橡胶复合材料的影响

Effect of ceramic fillers on properties of ethylene-propylene-diene monomer rubber composites

以玻璃粉、云母粉和蒙脱土为陶瓷化填料,制备可陶瓷化三元乙丙橡胶复合材料。采用极限氧指数、垂直燃烧、电子万能试验机、扫描电子显微镜等测试手段,研究陶瓷化填料对复合材料及其烧结后陶瓷体结构和性能的影响。结果表明,陶瓷化填料能够一定程度上提升复合材料的阻燃性能和力学性能;同时,玻璃粉含量的提升以及烧结温度的升高均能有效提升陶瓷体的完整性和力学性能。

The ceramifiable EPDM composite was prepared using glass powder,mica powder and montmorillonite as ceramic filler.The effects of ceramic fillers on the structure and properties of composites and their sintered ceramics were investigated by means of limiting oxygen index,vertical combustion,electronic universal testing machine and scanning electron microscope.The results show that the ceramic filler can improve the flame retardant and mechanical properties of the composite to a certain extent.Moreover,the content of the glass powder and sintering temperature can effectively improve the integrity and mechanical properties of the ceramic.
