【摘要】 本文综述了国内外功能高分子材料的发展与趋势,尤其是建筑功能材料的发展及发展趋势,阐述了建筑功能材料给人类生活带来的污染以及人类对生态建筑和高质量生活环境的迫切需求,提出了利用天然矿物海鸥石制备负离子功能添加剂,以苯丙乳胶为载体,充分开发利用天然矿物没有放射性,能释放负离子的特点,对苯丙涂料进行改性研究,来增加人们生活环境中的负离子含量,进而提高人类生活环境的空气质量。本文采用纳米粒子添加剂对苯丙涂料进行改性,制备了纳米粒子生态健康涂料,利用XRD、SEM、TEM、抗菌实验对涂料成分、结构、性能进行分析,对涂料的常规性能进行检测分析。结果表明:在海鸥石(Health)中存在着变价Fe元素,这些变价的Fe原子会产生微电场,当空气中的水分子进入海鸥石(Health)的微孔时,水分子被电离,产生负离子;另外,海鸥石含有的TiO2具有光电催化作用,能把细菌和病毒等有机物彻底氧化为CO2和H2O;海鸥石内部具有20-60nm的孔隙结构;纳米助剂的最佳添加量为m(CaCO3): m(ZnO): m(Anion) = 2:2:3,生态健康涂料对金黄色葡萄球菌、大肠杆菌、白色念珠菌、枯草杆菌具有很好的抗菌作用,抗菌率均在90%以上,水洗50次后,抗菌率依然达到90%;当海鸥石负离子添加剂添加量为3%时,生态健康涂料的常规性能均符合国家标准,而且负离子释放量最大达到1700个/cm3,满足了人们对健康的基本需求。

【Abstract】 The paper has focused on the development of functional materials in domestic and abroad especially the development of building materials. The pollution brought by functional materials and the demands for high-qualified life are also illustrated. The benzedrine dope was modified with natural Heath functional additives. The modified dope was able to release anions and to improve ecotype environment for human beings.The benzedrine dope was modified with nano-particles to prepare ecotypic and healthy dope. The XRD, SEM, TEM and anti-bacteria testing were performed on Health-modified benzedrine dope to analyze the chemical properties, structure, properties and routine performances upon application. The results show that valence-variable Fe atoms locate in Health, producing micro-electric field. As water molecules pass through Health holes, they are dissociated into H+ and OH-. H+ ions with positive charge function with each other, and anions remained. TiO2 contained in Health break down organic substance into CO2 and H2O due to phonic-catalytic effects, fundamentally killing bacteria and virus. Some holes with size of 20-60 nm exist in Health. The optimum nano-additives content is m(CaCO3): m(ZnO): m(Anion) = 2:2:3. The modified benzedrine dope showed excellent anti-bacteria functions to golden staphylococcus, E. coli, Candida alb cans and B. subtitles, and the anti-bacteria ratio is more than 90% even after 50 times water bath. When 3% additives are added, the benzedrine dope achieves national standard and released 1700 anions/cm3, meeting demands for human health.
