摘要: 综述了聚丁二酸丁二醇酯(PBS)及其共混物的制备及应用进展。目前国内外PBS的合成工艺主要有直接酯化法、酯交换法和扩链法。PBS的耐热性好、力学性能优良,是可完全生物降解的脂肪族聚酯,能从根本上解决塑料白色污染的重要材料之一。PBS与脆性可降解聚酯共混可以提高其韧性和生物降解性;通过与其他可再生资源如热塑性淀粉、木薯淀粉、开心果壳粉共混可以提高刚性和熔点,改善力学性能的同时降低成本;与少量无机填料如碳酸钙、二氧化硅等共混不仅可以降低PBS的价格还可以改善PBS的性能。PBS目前主要应用于包装材料、农林业用品、日用杂品、纺织业及医用制品中。PBS作为薄膜应用时其力学性能及气体阻隔性能是两项重要的指标,所以重点总结了对PBS复合膜的力学和阻隔性能的改善研究进展。最后对PBS未来的研究和发展方向进行了展望,指出PBS生产技术应该向综合性能高、成本低和绿色环保方向发展。

Abstract: The paper reviewed the research progress in the preparation and applications of poly(butylene succinate)(PBS) and its blends. The current main synthesis technologies of PBS at home and abroad include direct esterification, transesterification, and chain extension. PBS is a type of completely biodegradable aliphatic polyester with good heat resistance and excellent mechanical properties, and it is capable of fundamentally solving the plastic white pollution as one of the most important biodegradable materials. The PBS blends with other brittle degradable polyesters can improve its toughness and biodegradability. Through blending with other renewable resources, The PBS blends can obtain an increase in rigidity, melting point, and mechanical properties, but a decrease in the cost. Through blending with a small quantity of inorganic fillers such as calcium carbonate and silica, PBS obtained not only a decrease in price but also an improvement in performance. In the present, PBS is mainly used in packaging materials, agricultural and forestry supplies, household goods, textiles, and medical products. The mechanical and gas barrier properties of PBS are two important indicators for its thin films. This review focused on the research progress in improving the mechanical properties and gas barrier properties of PBS composite films. Finally, the future research and development direction of PBS was prospected. The future direction in the PBS production technology will be to develop PBS products with high comprehensive performance, low cost, and green environment protection.
