Abstract

The invention discloses a preparation method of a self-cleaning building coating. The preparation method comprises the following steps: preparing raw materials according to a weight ratio to prepare afirst mixture, a second mixture and a third mixture; mixing the first mixture and 55-60 wt% of the third mixture to prepare an emulsion, stirring the emulsion for 10-15 minutes at 35-38 DEG C to prepare an emulsion, adding the rest of the third mixture, and uniformly stirring the emulsion at room temperature; and cooling the emulsion to room temperature, adjusting the pH value of the emulsion to7-7.5 by using a pH regulator, adding the second mixture, and fully and uniformly stirring the mixture to obtain the self-cleaning building coating. Compared with the prior art, the self-cleaning building coating prepared through the preparation method of the self-cleaning building coating is environmentally friendly and good in self-cleaning performance.

Description

【Technical field】 [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of self-cleaning architectural paint. 【Background technique】 [0002] As one of the most commonly used building materials, paint is a general term for a class of liquid or solid materials that can form a solid coating film with protection, decoration or special properties (such as insulation, anti-corrosion, signs, etc.) when applied to the surface of an object. Including paint, water-based paint, wood paint, powder coating, wood wax oil, essential for house decoration. [0003] At present, more and more exterior walls are also painted with paint to prevent the tiles from falling after being pasted for a long time, causing personal injury. However, most of the paints currently used in mass production on the market are solvent-based, containing a large amount of volatile organic solvents, which not only pollute the environment and was...
