Abstract

The invention relates to the technical field of coatings, and provides a galling wall solid coating for old wall renovation. The galling wall solid coating for old wall renovation comprises a first component and a second component, and the first component comprises, by weight, 15-25 parts of an emulsion, 0.1-0.3 part of a water reducer, 0.5-0.8 part of cellulose, 3-6 parts of a hydrophobic agent, 1.5-5.5 parts of an auxiliary agent, and 65-75 parts of water; the second component comprises, by weight, 5-15 parts of quartz sand and 85-95 parts of cement; and the mass ratio of the first component to the second component is 1: (2-2.5). The coating provided by the invention is easy to construct, good in bonding strength, excellent in acid and alkali resistance and excellent in ultraviolet aging resistance, and can better improve the adhesive force between a reinforced old wall surface and a new coating.

Description

technical field [0001] The application belongs to the technical field of coatings, and in particular relates to a roughened wall solid coating for renovation of old walls and a preparation method thereof. Background technique [0002] With the continuous development of real estate, people's requirements for indoor and outdoor decoration are also getting higher and higher. After decades of real estate development, there are a large number of old houses whose walls need to be refurbished. If the old wall is refurbished, if the bonding between the old wall and the new wall is not properly handled, the hidden danger of the wall falling will easily occur. Therefore, the old wall renovation should pay attention to the treatment of the old wall, especially in the old tiles. On the smooth surface, an adhesive with excellent bonding strength is required to carry out the next renovation work. [0003] Renovation of old walls often requires interface treatment of the old walls, espec...
