摘　　要：用炔醇聚醚有机硅(HBBP)与聚醚三硅氧烷(PTS)进行复配,探究HBBP聚合度(P2-4、P3-4、P5-4和P6-4)对PTS表面活性剂水溶液平衡表面张力、动态表面张力、低能表面润湿性及泡沫性能的影响。结果表明,加入HBBP对PTS水溶液表面活性及润湿性的影响较小,但对PTS这类低表面张力体系具有较好的泡沫控制效果,而且随着硅氧烷链段的增长,消泡效果越显著。Alkynol polyether silicone(HBBP)was compounded with polyether trisiloxane(PTS).The ef⁃fects of HBBP with different polymerization degrees(P2-4,P3-4,P5-4 and P6-4)on equilibrium surface ten⁃sion,dynamic surface tension,wettability and foam properties of PTS surfactants in aqueous solutions was in⁃vestigated.The results showed that the addition of HBBP has little effect on the surface activity and wettabili⁃ty of PTS aqueous solution,but it had a better foam control effect on low surface tension systems such as PTS.With the increase of siloxane chain length,the defoaming effect of HBBP was more significant.
