摘要:

以苯乙烯(St)、丙烯酸异辛酯(2-EHA)为主要单体采用预乳化半连续种子乳液聚合工艺合成了苯丙乳液。用激光粒度仪测试了乳胶粒粒径大小及粒度分布, 用差示扫描量热法(DSC)测试了共聚物的玻璃化转变温度, 用流变仪测量了乳液的流变性能, 研究了单体配比、交联剂用量以及乳化剂用量对乳胶粒粒径、乳液的稳定性、流变性、粘结性能的影响。结果表明: 合成的苯丙乳液为假塑型流体; 乳液的粘度随着2-EHA/St配比、交联剂用量和乳化剂用量的增加而升高; 乳液的稳定性随着乳化剂用量的增大而提高, 随着交联剂用量的增大而降低; 乳液胶膜的粘结性随着交联剂用量以及2-EHA/St配比的增大而增强; 乳胶粒的粒径随着乳化剂用量的增加而变小, 随着交联剂用量的增加而变大。

Abstract：

The styrene-acrylic emulsion was synthesized by pre-emulsified semi-continuous seeded emulsion polymerization, with styrene (St) and 2-ethylhexyl acrylate (2-EHA) as main monomers. The particle size distributions were characterized by laser particle size analyzer, the glass transition temperatures were measured by DSC, and the rheological behaviors were analyzed by rheometer. The effects of monomer-proportion, the amount of cross-linking agent and emulsifiers on particle sizes, emulsion stabilities, rheological behaviors and bonding properties were investigated. The results show that styrene-acrylic emulsion is a pseudoplastic fluid, and the viscosity enhanced with the increase of the ratio of 2-EHA/St, the amount of cross-linking agent or emulsifiers. The emulsions stabilize with the increment of emulsifiers, while destabilize with the increment of cross-linking agent. The shear bond strength enhances with the increment of cross-linking agent or the ratio of 2-EHA/St. The particle size of emulsions decreases with the increment of emulsifiers, while increases with the increment of cross-linking agent.

Key words： organic polymer materials styrene-acrylic emulsion polymerization rheology particle size distribution glass transition temperature
