中文摘要:
      采用传统高分子成型设备，改造模压成型模具，制备胶粉弹性体，研究模压弹性体性能的影响因素。结果表明：模压成型压力是影响胶粉模压弹性体性能的重要因素，增大模压成型压力，模压弹性体交联程度增大，物理性能改善；胶粉活化改性使胶粉降解程度增大，不利于胶粉模压成型；以天然橡胶作为粘合剂的胶粉模压弹性体强伸性能明显提高，可以满足部分在静态或低速状态下使用的橡胶制品要求。
英文摘要:
      In this study，the molded elastomer was prepared with reclaimed rubber powder from waste tire using modified press molding molds and conventional press molding equipment.The factors influencing the properties of the molded elastomer were investigated.The experimental results showed that molding pressure was an important factor affecting the performance of molded elastomer.It was found that increase of compression molding pressure would increase the degree of crosslinking and improve the physical properties. Powder activation modification increased the degree of degradation and made it difficult for press molding. The addition of NR as a binder could improve the tensile properties significantly and the molded elastomer met requirements of some rubber products used in the static and low speed applications.
