摘要
以提取竹纤维素为交联剂,采用半连续乳液聚合法合成制备竹纤维素-丙烯酸酯乳液型压敏胶。结果表明:聚合体系温度85℃,搅拌速率为150 r/min,聚合3 h,当软硬单体的体积比4∶1,硬单体中甲基丙烯酸与醋酸乙烯酯体积比为1∶4,引发剂用量为总量的0.30%,竹纤维素添加量为总质量的0.6%,反应时间为3 h,可制备得到性能良好的压敏胶,其黏度为21.3 mPa.s,剥离强度为0.692 N/mm,可为新型竹纤维素基质压敏胶研究提供有益参考。
Using bamboo cellulose as raw materials, bamboo cellulose-acrylate emulsion pressure-sensitive adhesive was synthe- tized by semi-continuous emulsion polymerization method. The results showed that： when the polymerization system temperature 85 ℃, stirring rate 150 r/min, the hard and soft monomer ratio 4： 1, hard monomers methacrylic acid： vinyl acetate 1：4, initiator dosage 0.30 %, adding 0.6 % of the total mass fraction of bamboo cellulose and reaction time of 3 h were used, good performance pressure-sensitive adhesive with viscosity of 21.3 mPa. s, the peel strength of 0.692 N/mm could be obtained, The results provide a useful reference for the new bamboo cellulose matrix pressure-sensitive adhesive.
