摘要
根据生物降解性塑料完全转化为水和二氧化碳必经过程:吸水、水解和微生物浸蚀的降解机理,采用吸水性、碱液水解测试和土埋法,研究了淀粉、滑石粉、碳酸钙填充聚己二酸/对苯二甲酸丁二酯(PBAT)复合材料的降解特性。结果表明:淀粉填充PBAT体系有最强的吸水性。淀粉含量越多,碱液浓度越高,水解速度和生物降解速度越快。
According to the necessary process that the biodegradable plastics completely turn into water and CO2, the degradation behavior of the poly（butylenes-adipate-co-terephthalate）（PBAT） filled by starch, talcum powder and CaCO3 was investigated by water absorption test, alkaline hydrolysis test and soil burial test. The result show that： the water absorption of PBAT filling with starch is the best. The more content of the starch and higher concentration of the alkaline are used, the faster hydrolysis rate and the biodegradation of the composite are.
