Abstract

Hydroxyethyl methacrylate (HEMA) is a crucial functional monomer in acrylate adhesives. A series of waterborne acrylate adhesives with varying HEMA contents were synthesized and evaluated based on their viscosity, particle size, and peel strength. The particle size of the emulsion remained consistent around 200 nm across different HEMA contents, suggesting minimal impact from HEMA. The emulsion with 0.5 wt% HEMA exhibited a viscosity of 42.44 mPa s, indicating excellent fluidity. Rheological tests showed that HEMA increased the cohesive energy of the adhesive, with 0.5 wt% HEMA demonstrating optimum chain flexibility and elasticity in the latex film. On a biaxial oriented polypropylene (BOPP) substrate, the adhesive with 0.5 wt% HEMA achieved the highest adhesive strength of 2.96 N/25 mm, attributed to its superior wetting ability and chain flexibility, meeting the requirements for BOPP film adhesion.

甲基丙烯酸羟乙酯对水性丙烯酸酯胶粘剂性能的影响

甲基丙烯酸羟乙酯（HEMA）是丙烯酸酯粘合剂中的一种重要功能单体。我们合成了一系列 HEMA 含量不同的水性丙烯酸酯粘合剂，并根据粘度、粒度和剥离强度对其进行了评估。在不同的 HEMA 含量下，乳液的粒度始终保持在 200 nm 左右，这表明 HEMA 的影响极小。HEMA 含量为 0.5 wt% 的乳液粘度为 42.44 mPa s，表明流动性极佳。流变测试表明，HEMA 增加了粘合剂的内聚能，0.5 wt% 的 HEMA 在胶乳薄膜中表现出最佳的链柔性和弹性。在双向拉伸聚丙烯（BOPP）基材上，0.5 wt% HEMA 粘合剂的粘合强度最高，达到 2.96 N/25 mm，这归功于其出色的润湿能力和链柔韧性，符合 BOPP 薄膜粘合的要求。
