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一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150r／min，聚合3h，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3h，可制备得到性能良好的压敏胶，其黏度为21．3mPa·S，剥离强度为0．692N／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.
