白泥在汽车密封条中的应用
|
摘要
使用硅烷偶联剂Si69对白泥进行表面改性,将改性白泥做为补强填料应用于汽车橡胶密封条中,并与白炭黑和碳酸钙等填料的补强效果进行了对比。研究了Si69的最佳质量分数及改性白泥对混炼胶硫化特性以及硫化试样的硬度、拉伸强度、断裂伸长率、撕裂强度、压缩永久变形和老化性能的影响。结果表明,用质量分数2%的Si69改性后的白泥对橡胶的补强效果最好,在等质量分别替代白炭黑和轻质碳酸钙使用时,硫化胶的各项性能均有所上升;在硫化胶性能保持不变的情况下可以增加改性白泥的填充量。
White clay modified by coupling agent Si69 was used as the reinforced fillers for automobile rubber sealing strip. And its reinforcing properties were compared with those of the white clay modified with silica and calcium carbonate. The effects of white clay modified by different mass fractions of Si69 on vulcanization characteristics of mixed rubber and hardness,tensile strength,elongation at break,tearing strength,compression set and aging properties of vulcanized samples were investigated and the optimum mass fraction of coupling agent Si69 was decided. The results show that the white clay modified by coupling agent Si69 with mass fraction of 2% has the best reinforcing performances on the rubber. When Si69 respectively replace white carbon black or calcium carbonate with the same amount of addition,the performances of the vulcanized rubber improve. And the filling amount of white clay can be increased while the performance of the vulcanized rubber is not changed.
