摘　　要：为解决盾尾密封油脂在生产制备过程中增黏剂的选取和用量问题,分别选取松香树脂、萜烯树脂、古马隆树脂以及聚异丁烯四种增黏剂进行试验研究。试验结合盾尾密封油脂的产品特性和使用要求,通过比较其泵送性、表观粘度、抗水压密封性、粘附性和锥入度等指标,最终筛选出综合效果最佳的聚异丁烯增黏剂,确定其最佳用量为8%~10%。有助于工程实践中更好的提高盾尾密封油脂的使用性能。In order to solve the problem of the selection and dosage of tackifiers in the production process of shield tail sealing grease,four tackifiers,rosin resin,terpene resin,coumarone resin and polyisobutylene were selected for experimental research.The test combined the product characteristics and application requirements of the shield tail sealing grease,and compared its pumpability,apparent viscosity,water pressure resistance,sealability,adhesion,and penetration,and finally screened out the polyisobutylene with the best overall effect.As for the tackifier,the optimal dosage is 8%~10%.It helps to better improve the performance of shield tail sealing grease in engineering practice.
