| 摘 要： | 采用预乳化法制备了丙烯酸酯压敏胶乳液,探讨了不同乳化剂体系对压敏胶物理性能的影响。FTIR测试表明,反应型乳化剂参与了反应;TEM测试显示,反应型乳化剂体系所得乳液粒径小,分布均匀。实验结果表明:当w(复合乳化剂)=3%,m(ANPEO10)∶m(DNS-458)∶m(DNS-501)=1.5∶1.1∶0.4时,所得乳液的固体分质量分数为48.03%,单体转化率达到97.66%,乳液黏度为38.8 s,平均粒径为238 nm,压敏胶的初粘力能吸住8号钢球,持黏性大于24 h,180°剥离强度达到0.304 N/mm。贴在不锈钢表面的保护膜经80℃烘烤24 h后,不锈钢表面无残胶和雾影。

| Abstract: | The pressure-sensitive adhesive(PSA) of acrylic emulsion were synthesized by pre-emulsion polymerization,and the effects of different kinds of emulsifier systems on the physical properties of PSA were discussed.The emulsion and their films were characterized by FTIR and TEM.The results show that reactive emulsifier is effectively involved in the copolymerization,and the synthesized polymer emulsion has smaller particle sizes and good distribution.When w(compound emulsifiers)=3%(based on total monomers),and ... |
