Abstract

The invention provides high-adhesion super-hydrophilic coating for a glass curtain wall. Amorphous nano silicon dioxide has super-hydrophilic and adhesive force increasing effects; silicate has relatively strong hydrophilic property and thickening capacity for an external phase of an emulsified body; ethanol is used as a solvent, isopropanol is used as a cosolvent, propylene glycol monomethyl ether is used as an auxiliary film-forming agent, and n-propanol can improve the compatibility of various materials, has the effects of dissolving and reducing surface tension, is convenient for leveling,and is beneficial to spreading and film-forming of the coating; a silane coupling agent can improve the adhesion and improve the dispersity of a filler; a titanium dioxide solution has photocatalyticperformance, so that a self-cleaning function of the coating is improved. All the raw materials are matched with one another; in the using process, the interface of the coating and a base material forms a silane-coating interpenetrating net-shaped structure, the cohesion and stability of water erosion resistance of the coating are enhanced, stress is transferred from a high-modulus base materialto a low-modulus coating base material, and therefore, the adhesive force of a coating layer to the base material is remarkably improved.

Description

technical field [0001] The invention belongs to the field of self-cleaning materials, and in particular relates to a high-adhesion superhydrophilic coating, its preparation method and application. Background technique [0002] Glass curtain wall is a kind of beautiful and novel building wall decoration method, and it is a remarkable feature in the era of modernist high-rise buildings. It usually has two kinds of single-layer glass and double-layer glass. Glass curtain wall refers to the building envelope or decoration structure whose supporting structure system has a certain displacement capacity relative to the main structure and does not share the effect of the main structure. At present, the environmental pollution of the city is intensifying, among which dust pollution and gas pollution are particularly serious. Seriously, the outer walls of buildings, especially high-rise buildings, are being corroded more and more seriously. Due to the surface oil, it is difficult to c...
