The negative ion concentration is just the same as the concentration in a city - park . so it ' s just as if we built a small park indoors . it ' s very significative for improving people ' s living condition 在模拟普通房间内涂刷所研制的稀土激活内墙涂料，测得房间内负离子数在800 - 1000个/ cm ~ 3之间，已经接近都市公园里的负离子数，相当于在居室内人造了一个小型公园，这对改善人们的居住环境具有划时代的意义。
Ftir , thermal conductivity device and smart digital rounding temperature testing device are used to test the infrared absorption spectrum , thermal conductivity and temperature changes of the title coatings , it is concluded that when hudrotalcite and magnesium sulfate is mixed by 4 to 10 , the heat insulation property is the best , and the temperature changes of nizi increased by 5 approximately compared with those without hydrotalcite and magnesium sulfate compound system , but the heat conduction coefficient is hardly increased because of the different mechanism of heat insulation of the fillers , which further prove that heat insulation with fillers is based on infrared barrier 本文使用傅里叶变换红外光谱仪、导热系数仪和智能数字式巡回检测温度测试仪分别测试了添加具有红外阻隔能力填料的内墙涂料的红外吸收光谱、导热系数和温度变化情况，通过测试结果得出结论：水滑石和硫酸镁在质量比为4 : 10的时候，红外阻隔性能最优，其温差变化较没有添加水滑石硫酸镁复合体系时提高5左右，而对内墙涂料的导热系数几乎没有影响,这是由于填料对涂料的保温机理不同所致，同时也进一步验证了填料是通过红外阻隔来达到保温效果的。
The coatings are tested comply with the requirements of national standards gb / t 9756 - 2001 , the synthesis performance exceed the index of first - rank production , in the same time the average antibacterial rate of these inorganic materials can reach 90 percent . when the weight amount of the inorganic antibacterial powder of ag + and ce2 + reaches 2 percent , the antibacterial rate of the coating is 99 . 976 percent 通过检测发现，样品性能完全符合并超过合成树脂乳液内墙涂料标准中对一等品的要求，同时抗菌效果可达到90 . 0以上，当多孔纳米sio _ 2载银、铈材料在涂料中的添加量为2 ( wt )时，改性涂料的抗菌率可达到99 . 976 。
Developing advanced environmental - friendly building materials by combing functional materials with building materials has become a recent tendency in the development of the building materials . the infrared radiation inner wall coating exhibiting ecological characteristics such as antibacterial function and health protection function is a novel kind of the inner wall coating , in which the ceramic powders with fine infrared radiation properties are the key materials 功能材料与建筑材料相结合以制备新型环境友好型建筑材料是目前建筑材料的发展趋势之一，研制和开发具有抑菌、保健等生态功能的红外辐射内墙涂料是近年来国际上内墙涂料新的发展动态，高性能的红外辐射材料是发展环境友好型红外辐射内墙涂料的关键材料。
