摘　　要：研究了基体橡胶、基体树脂、增黏剂、填料和软化剂对非硫化丁基橡胶防水密封材料持粘性和剥离强度的影响。结果表明,三元乙丙橡胶可以提高非硫化丁基橡胶防水密封材料的内聚强度、降低粘合力;高分子量聚异丁烯的掺入可以增加非硫化丁基橡胶防水密封材料的内聚强度和粘结强度;萜烯树脂作为增黏树脂对材料粘结强度的提升效果显著;较高掺量的轻质碳酸钙仍可保证材料具有良好的内聚强度和粘结强度。此外,适量的炭黑和石蜡油的掺入能有效提升体系的综合性能。The influence of matrix rubber,matrix resin,thickening agent,filler and softening agent on holding power and peeling strength of unvulcanized butyl rubber waterproofing sealing material was studied.The results indicate that EPDM can improve its cohesive strength and reduce adhesive power;adding polyisobutylene having high molecular weight can improve its cohesive strength and adhesive power;terpine resin as thickening agent has significant effect of increasing its adhesive power; more addition of light calcium carbonate still can make it have good cohesive strength and adhesive power.In addition,adding appropriate carbon black and paraffin oil can efficiently improve comprehensive performance of the system.
