Abstract

The invention provides a hydrophobic coating for an external wall. The coating is prepared from the following components in parts by mass: 10-20 parts of a film forming emulsion, 8-15 parts of triplesuperphosphate, 5-10 parts of titanium dioxide, 1-3 parts of a film forming aid, 2-5 parts of a defoamer, 1-5 parts of a dispersing agent, 2-10 parts of a lotus leaf hydrophobic agent, 1-3 parts of awetting agent, 3-10 parts of a preservative, 0.3-1 part of a bactericide, 1-8 parts of a thickener, 3-8 parts of a light stabilizer, 40-60 parts of deionized water, 1-4 parts of kaolin, 5-15 parts ofnano far-infrared ceramic powder and 0.2-1 part of a PH regulator. The hydrophobic coating for the external wall has the advantages that hydrophobic performance is good, the external wall of a building is convenient to clean, the coating is prevented from being damaged, labor intensity is reduced, and the hydrophobic coating is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of exterior wall coatings, in particular to a hydrophobic coating for exterior walls. Background technique [0002] With the improvement of the construction level, the buildings are getting taller and taller, which brings a lot of inconvenience to the cleaning. On the other hand, the small and medium-sized advertisements in the city are full of the outer walls of the buildings. When cleaning, the outer coating of the walls is often damaged. How to clean them conveniently? It has become a thorny problem that the rubbish on the exterior wall of the building will not damage the coating. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydrophobic coating for exterior walls, so as to facilitate the removal of surface garbage. [0004] The present invention solves the above technical problems through the following technical solutions: [0005] A hy...
