Problems solved by technology

[0004] However, nano-titanium dioxide has a large specific surface area, high surface energy, and a hydrophilic and oleophobic surface. It is very easy to agglomerate in the polymer. The agglomeration will greatly reduce the performance of titanium dioxide, reduce the photocatalytic activity of the titanium dioxide film, and then affect the self-cleaning ability.
The publication number is CN105111401A, which discloses a nano-titanium dioxide self-cleaning coating, but the dispersion of nano-titanium dioxide in this coating is not uniform enough, and it is easy to agglomerate, which affects the self-cleaning effect of the product

Abstract

The invention belongs to the technical field of construction, and particularly relates to a fireproofing self-cleaning wall and a method for preparing the self-cleaning coating layer of the self-cleaning wall. The fireproofing self-cleaning wall comprises a first building block layer, a sound insulation layer, a second building block layer, a fireproofing layer and a self-cleaning layer. The sound insulation layer includes a sound insulation body and a plurality of strip-shaped sound insulation boards; the inner cavity of the sound insulation body is divided into a plurality of accommodating cavities through a plurality of strip shaped sound insulation boards; arc-shaped sound insulation boards are arranged on the accommodating cavities in a longitudinal symmetry mode; two ends of the arc-shaped sound insulation boards are respectively connected with the tops of the strip shaped sound insulation boards adjacent to the arc shaped sound insulation boards. An arc-shaped accommodating cavity is arranged between the arc-shaped sound insulation boards and the top walls of sound insulation body, and a vacuum bag is arranged in the arc-shaped accommodating cavity. The self-cleaning coating layer is nano titanium dioxide self-cleaning coating layer. The fireproofing self-cleaning wall has the advantages of being high in fire resistance, good in sound insulation effect, and excellent in self cleaning ability.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a method for preparing a fireproof self-cleaning wall and a self-cleaning coating for the self-cleaning wall. Background technique [0002] With the rapid development of my country's construction industry, building walls are favored by architects because of their advantages such as windproof, rainproof, heat preservation, heat insulation, noise prevention, air penetration resistance and decoration. But the way it's cleaned hasn't changed in any way. Manual cleaning is neither convenient nor safe. In addition, long-term use of cleaning agents not only wastes resources, but also pollutes the environment, which is not in line with the current environmental protection and conservation policies advocated by the state. Therefore, research on the preparation of self-cleaning building walls has become a hot topic. [0003] Studies have shown that titanium dioxide has fun...
