1、四川大学硕士学位论文无机纳米粉体材料改性的抗菌内墙乳胶漆研究材料学专业研究生李彦峰指导教师涂铭旌本文在内墙乳胶漆应用现状的基础上,提出了使用无机纳米粉体材料改性内墙乳胶漆抗菌性能的创新思路,比较系统地研究了纳米粉体材料的种类和添加量等因素对内墙乳胶漆抗菌性能的影响,成功开发了纳米改性抗菌内墙乳胶漆产品,并完成了内墙乳胶漆用纳米抗菌助剂的开发。的要求,同时抗菌效果可达到90.0%以上,当多孔纳米si02载银、铈材料征袜料中的添加量为2%(叭)时,改性涂料的抗菌率可达到99.9.76%。为使纳米材料在涂料中具
2、有更好的分散性,以便改性涂料的性能更为优越,本文研究了经过预分散的抗菌纳米复合浆料,这种浆料可以很方便地添加到普通水性涂料中.在添加量很少时(2训%)即可达到很好的抗菌效果,此时抗菌率达到99.97%。关键词:纳米材料抗菌乳胶漆改性四川大学硕士学位论文StudyorlTheAntibacterialPropertyofInorganicNanopowderMaterialsModifiedCoatingsMajor:MaterialPostgraduate:YanfengLiSupervisor:Ming
