Description

technical field [0001] The invention relates to the technical field of architectural decoration functional coatings, in particular to an inorganic silicate coating for urban greenways and a preparation method thereof. Background technique [0002] The concept of "sponge city" was first proposed in the "2012 Low-Carbon City and Regional Development Science and Technology Forum", which is to take measures such as infiltration, stagnation, storage, purification, use, and drainage, and give priority to the limited rainwater when upgrading the urban drainage system. In the future, priority should be given to the use of natural power to drain water, and to build a sponge city with natural accumulation, natural penetration, and natural purification. Urban greenway is a green open space that can be entered by pedestrians and cyclists, has good natural landscape, and is mainly for leisure functions, which can fully reflect the humanistic atmosphere of the city. How to incorporate ur...
