生物基施胶剂制备及在纸张中应用研究进展

Research Progress on Synthesis of Bio-based Sizing Agents and Its Application in Paper Packaging Material

目的综述国内外生物基施胶剂的最新研究进展,为高品质生物基施胶剂的工业化开发提供思路和理论依据。方法在理解施胶机理的基础上,对现有生物基施胶剂(松香施胶剂、植物油基施胶剂和多糖施胶剂)的结构和性能“构效关系”进行归纳、总结和分析。结果通过对生物基原料进行可控物理和化学改性,在不破坏纸张强度的基础上赋予纸张优良的防水、耐油、水蒸气阻隔等特性。结论生物基施胶剂具有原料来源广泛、结构可调、无毒和可生物降解等突出优点,在未来纸包装材料中具有广阔的应用前景。

The work aims to review the latest research progress of bio-based sizing agents at home and abroad and provide ideas and theoretical basis for the industrial development of high quality bio-based sizing agents.Based on the understanding of the sizing mechanism,the"structure-function relationship"of existing bio-based sizing agents(rosin sizing agents,plant oil sizing agents and polysaccharide sizing agents)was summarized and analyzed.By controlling the physical and chemical modification of the bio-based raw materials,the functional bio-based sizing agents with excellent water resistance,oil resistance,together with water vapor barrier were obtained without destroying the strength of the paper.Bio-based sizing agent with advantages of wide raw material sources,adjustable structure,non-toxicity and biodegradability have broad application prospects in the future paper packaging materials.
