摘要
利用三种不同的乳化剂体系合成丙烯酸酯乳液压敏胶粘剂 ,研究了乳化剂体系对产物分子量、分子量分布以及对压敏胶各项性能的影响。结果表明 ,用阴离子乳化剂 制得的乳液具有较高的平均分子量 ,持粘性好 ,但乳液的稳定性较差。而用复合乳化剂 制备的乳液的平均分子量较低 ,持粘性差 ,但乳液的稳定性好。用复合乳化剂
Acrylic pressure sensitive adhesive (PSA) emulsions are obtained by using three differrent emulsifier systems.The effects of emulsifier systems on average molecular weight,molecular weight distribution and properties of PSA emulsions are studied.The results indicate that emulsions using anionic emulsifier I has high average molecular weight,excellent cohesion and bad stability.Emulsions using complex emulsifier Ⅲ has low molecular weight,bad cohesion and excellent stability,emulsions using complex emulsifier Ⅱ has good balanced properties.
