摘　　要：探讨了基质沥青、增塑剂、橡胶改性剂、增黏剂、填料、搅拌时间和搅拌速度对自粘聚合物改性沥青防水卷材配方性能的影响,指出基质沥青应选用低温柔性好、粘结性高、相容性好、蜡含量低的品种,增塑剂、橡胶改性剂、增黏剂、填料等对自粘卷材的性能有一定的改善作用,但都不宜过量,试验中应严格控制搅拌时间和搅拌速度。This article discusses factors influencing the performance of self-adhered polymer modified asphalt waterproofing membrane,such as asphalt,plasticizer,rubber modifier,tackifier,filler,mixture time and mixing speed.It points out that the asphalt with excellent low temperature flexibility,bond strength,compatibility and low wax content should be chosen.The plasticizer,rubber modifier,tackifier and filler can improve the performance of the membrane to some degree,but their dosages should not be excessive.The mixture time and mixing speed should be strictly controlled as well.
