摘　　要：研究了乙烯基三乙氧基硅烷(A-151)对丙烯酸酯乳液共聚改性时A-151用量对乳液胶粘剂性能的影响。结果表明,当A-151用量少于单体量的7%时,丙烯酸酯乳液胶粘剂的剥离强度提高;随其含量的增加,黏度增大,剥离强度开始降低,乳液的吸水性降低,耐水性增强。当其含量为单体量的15%时,完全干燥后浸在水中胶膜不发白,可用于耐水涂层。Effect of vinyltrimethyloxysilane （A-151） amount on the performance of acrylate emulsion adhesives was studied during modifying of the adhesives by copolymerizing with A-151 .The resulats showed that when the A-151 amount was less than 7 wt% of monomers the peeling strength of adhesive was enhanced,but with increasing A-151 amount further the viscosity and water resistant were increased and the peeling strength and the water absorption of the emulsion were decreased.When the A-151 anaount was 15 wt% of monomers,the adhesive can he used as the water-resistant coating for it is not blanch white when it is immerged in water after it is absolutely dried.
