摘　　要：采用生物活性剂对无机粉体进行表面处理,利用碱性无机材料的吸水性能制备出含少量淀粉和碱性无机材料的光钙型可环境消纳聚乙烯制品,通过力学性能、ASTM生物降解性能和卫生性能等分析,结果表明,该制品达到了HJBZ12-2000标准中规定的包装制品的标准要求和生物降解率的技术要求。Inorganic powder modified by bio-active agent and starch were blended for preparing photo-calcium type environmental-friendly plastic materials containing a few starch and alkaline inorganic material. The mechanical performance, bio-degradability and sanitary capabilities of products were studied. The results showed that the products which were prepared in the experiment could meet the criteria of wrapper and bio-degradability, which was stipulated by HJBZ12-2000 about packaging products and bio-degradable ratio.
