摘　　要：以糠醛基单体甲基丙烯酸四氢糠基酯(THFMA)、歧化松香改性单体(DRM)为硬单体,及油脂基单体甲基丙烯酸月桂酯(LMA)为软单体,通过溶液聚合法分别合成了THFMA-LMA、DRM-LMA系列生物基压敏胶(PSA),详细探讨了硬单体与软单体组成比例、单体分子结构等对PSA性能的影响。研究结果表明:随着PSA中硬单体THFMA质量分数由10%增加到50%时,持黏力从0.48 h提高到72 h;且当THFMA质量分数为30%时,PSA的综合性能最佳,THFMA30-LMA的初黏力为2.28 N,180°剥离强度为143.6 N/m,持黏力达到21.25 h。另外与THFMA相比,以DRM作为硬单体在增强PSA力学性能的同时,还提高了PSA的热稳定性。In this work,furfural-based monomer tetrahydrofurfuryl methacrylate(THFMA),disproportionated rosin-based monomer(DRM),and oil-based monomer lauryl methacrylate(LMA)were used as raw materials to prepare a series of bio-based pressure-sensitive adhesives(PSA)based on THFMA/DRM/LMA by solution polymerization method.The effects of hard monomer and soft monomer composition ratio and the monomer molecular structure on the performance of PSA were investigated in detail.The results showed that the adhesion increased from 0.48 to 72 h with the increase of hard monomer THFMA in PSA from 10%to 50%.When the content of THFMA was 30%,the comprehensive performance of PSA was the best.The tack of THFMA30-LMA was 2.28 N,the 180°peel strength was 143.6 N/m,and the shear resistance reached 21.25 h.In addition,compared with THFMA,using DRM as hard monomer could enhance the mechanical properties of PSA and improve the thermal stability of PSA.
