Keyword:  抗菌EVA发泡材料载银磷酸锆偶联剂表面改性抗菌性能;
Abstract: 以乙烯-乙酸乙烯酯共聚物(EVA)为原料, 载银磷酸锆为抗菌剂,制备抗菌EVA发泡材料.采用硅烷、硼酸酯、铝酸酯3种偶联剂,分别对载银磷酸锆粉体表面改性.结果表明:采用硼酸酯改性的载银磷酸锆粉体,疏水性和分散性效果最好;含质量分数为1% 的载银磷酸锆(经2.5% 硼酸酯处理)的EVA发泡材料,其泡孔孔径增大,相对密度115 kg/m3, 拉伸强度2.02 MPa, 撕裂强度4.60 kN/m, 断裂伸长率 248%, 对大肠杆菌和金黄色葡萄球菌的抗菌率分别达到99.9% 和97.8%,物理力学性能和抗菌性能优良.
