| 摘要:本研究以蔗髓为原料，采用过氧乙酸预处理、微纳化分级、阳离子化改性等综合处理技术，制备了阳离子型蔗髓生物质微粒子（CPBP），重点讨论了CPBP回用为蔗渣浆造纸助剂后对浆料性能和纸张强度的影响规律。结果表明，使用质量分数10%过氧乙酸预处理可提高蔗髓微粒子（PBP）游离羟基含量，为阳离子化改性创造条件。在反应温度45 ℃、反应时间4 h，醚化剂3-氯-2-羟丙基三甲基氯化铵（CHPTAC）/PBP质量比1∶4条件下，制得的CPBP其Zeta电位为34.65 mV，电荷密度达4.12 mmol/g。蔗渣浆添加2.5份CPBP后，纸张抗张指数和撕裂指数分别提升37.0%和28.3%；向加填10份CaCO3蔗渣浆体系中加入2.5份CPBP，纸张抗张指数和撕裂指数相对于未添加CPBP分别提升34.4%和21.7%，滤水时间缩短了32.2%，并显著改善了CaCO3的留着效果。 |
| Abstract:In this study， using bagasse pith as the raw material， cationic sugarcane pith biomass microparticles (CPBP) were prepared by sequentially applying peracetic acid pretreatment， micro-nanization， and cationization modification. The study reused of sugarcane bagasse pulp as a papermaking additive， and the influence patterns of resuing CPBP as a additive for sugarcane sagasse pulp papermaking on the properties of the stock and the strength of the paper sheets. Using a 10% peracetic acid concentration for pretreatment increased the free hydroxyl content of the micro-particles (PBP)， which created conditions for cationic modification. Under the reaction temperature of 45 ℃ and reaction time of 4 h， with the etherifying agent 3-chloro-2-hydroxypropyl trimethyl ammonium chloride (CHPTAC) / PBP mass ratio of 1∶4， CPBP were obtained， with a Zeta potential of 34.65 mV and a charge density of 4.12 mmol/g. After adding 2.5 parts of CPBP to sugarcane bagasse pulp， the tensile index and tear index of the paper increased by 37.0% and 28.3%， respectively. When 2.5 parts of CPBP were added to the system filled with 10 parts of CaCO3， the tensile strength index and tear index of the paper increased by 34.4% and 21.7%， respectively， compared with those without CPBP， the drainage time was reduced by 32.2%， and the retention efficiency of CaCO₃ was significantly improved. |
