Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a water-based inorganic heat-insulating, waterproof and environmentally friendly coating for interior and exterior walls of buildings and a preparation method thereof. Background technique [0002] Buildings consume approximately 40% of the planet's total energy consumption, most of which is generated by heating and cooling facilities. Although there are many factors that affect the indoor temperature and the resulting air-conditioning and cooling energy consumption, such as climate, building structure, materials, etc., the roof and wall of the building carry more than 50% of the heat transfer between the building and the external environment, which is An important factor affecting the indoor ambient temperature. By blocking the heat transfer between the roof and the wall and the external environment, the temperature of the roof and the wall can be reduced, the he...
