Problems solved by technology

[0003] Based on the importance of energy saving and environmental protection of building wall coatings, people are also actively exploring the development and application of new energy-saving and environmental protection coatings; It still contains organic components; while the diatom mud coating that has emerged in recent years has better energy-saving and environmental protection effects, but its strength is not good, it is not resistant to water and dirt, and the price is too high
[0004] Traditional organic coatings are not heat-resistant. Under strong ultraviolet radiation in tropical island areas, many internal polymer chain breaks and

Abstract

The invention provides a multifunctional three-dimensional hydrophobic coating for buildings. The multifunctional three-dimensional hydrophobic coating comprises cement; magnesium oxide; magnesium sulfate; water; an additive; an anti-cracking agent; an auxiliary agent; a filler; and a foaming agent. Multi-component inorganic materials such as the magnesium oxysulfate cement and the mineral powder are adopted, special auxiliary materials are added, through a series of technological methods, the building coating integrating multiple functions of heat insulation, sound insulation, flame retardance, electromagnetic radiation absorption and the like and having three-dimensional hydrophobicity is successfully researched and developed, and the building coating can be applied to indoor and outdoor decoration of modern green buildings. And particularly, advanced building material support is provided for the building industry in tropical island areas. The invention further provides the multifunctional three-dimensional hydrophobic coating for the building.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, in particular to an architectural multifunctional three-dimensional hydrophobic coating and a coating.
