Abstract

The invention discloses a water-based nano-coating for thermal insulation of building walls, and relates to the technical field of nano-coatings. The water-based nano-coating prepared by the invention consists of a surface coating, an intermediate coating and a primer coating, and is suitable for using water as a diluting solvent. Improve the safety of use; and the surface coating formed by the surface coating has the functions of solar heat reflection, waterproof, and self-cleaning; Anti-corrosion function, so as to meet the requirements of the building wall for the use of coatings, ensure the quality of the coating, and prolong the service life of the coating.

Description

[0001] Technical field: [0002] The invention relates to the technical field of nano-coatings, in particular to a water-based nano-coating for thermal insulation of building walls. [0003] Background technique: [0004] In the existing technology, traditional thermal insulation materials such as rock wool felt, inorganic thermal insulation mortar, polystyrene foam board, foamed polyurethane, etc. are widely used, but the use of these thermal insulation materials must reach a certain thickness to have good thermal insulation performance , and the construction is time-consuming and laborious, and the construction quality determines its thermal insulation. However, the organic polymer foam material is used as the thermal insulation layer, which has poor flame resistance and has certain fire hazards. [0005] In recent years, both at home and abroad are committed to developing new thermal insulation materials to replace traditional thermal insulation materials. Among them, the ...
