一种杀菌型空气净化材料，由以下成分以重量份制备而成：白云石粉1份、大豆11S球蛋白1份、稻草碱木质素1份、乌拉草纤维0.5份、柚皮生物炭1份、碳分子筛1份、黄原酸壳聚糖1份、硅藻精土0.5份、荨麻叶乙醇提取物0.5份、纳米二氧化钛0.2份、粉煤灰0.1份、丙烯酸乳液2份、盐酸2份、去离子水100份。
上述杀菌型空气净化材料的制备方法为：
(1)将白云石粉、碳分子筛和硅藻精土混合研磨12h，得混合粉体；
(2)加入柚皮生物炭、纳米二氧化钛、粉煤灰、盐酸和一半去离子水，保鲜膜封口，用磁力搅拌机在转速90r/min，温度70℃下保温7h；
(3)过滤干燥，放入研磨机中研磨2h，过200目筛，去除大颗粒；
(4)加入稻草碱木质素、大豆11S球蛋白、荨麻叶乙醇提取物、乌拉草纤维、黄原酸壳聚糖、丙烯酸乳液和剩余去离子水，保鲜膜封口，用磁力搅拌机在转速110r/min下搅拌1h；
(5)过滤干燥即得。
表1杀菌型空气净化材料的各项性能指标
注：甲醛吸附试验和苯吸附试验中本发明材料的用量为1g，容积空间为5L
本发明材料的各项性能指标见下表，我们可以看到本发明材料对于甲醛和苯都具有很好的吸附效果，甲醛和苯的初始含量分别为0.409μg/L和1.31mg/L，经本材料吸附后，其含量最低分别仅为0.0110μg/L和0.0233μg/L，能够有效地吸附空气中的甲醛和苯，同时，本材料还具有很好的抗菌效果，对于大肠杆菌的抑制率可达到100％，可有效抑制细菌的繁殖，从而改善由其导致的吸附效果下降。
