Application of multifunctional building materials in urban high-rise buildings and its environmental adaptability analysis

In this paper, rare earth elements Ce and La are selected to modify TiO 2 hollow microspheres to prepare Ce-La/TiO 2 hollow microspheres, followed by the fusion of decanoic acid-palmitic acid composite phase change materials with Ce-La/TiO 2 hollow microspheres using vacuum adsorption method to prepare decanoic acid-palmitic acid@Ce-La/TiO 2 multifunctional materials for construction. Four application cases of multifunctional building materials are presented, and the environmental adaptability of the materials is also described and defined in detail, and finally, the applications of multifunctional building materials and their adaptability are analyzed. Multifunctional building materials in a variety of regional environments, have maintained excellent moisturizing effect, the degree of corrosion of traditional building materials is more serious than the degree of corrosion of multifunctional building materials, the difference between the two is about 0.13. Laying decanoic acid-palmitic acid@Ce-La/TiO 2 material on the traditional building materials can effectively improve their corrosion prevention performance.
