Problems solved by technology

[0009] In view of the currently widely used method of adding organic colloids to diatom mud, there are problems such as strong residual solvent odor, easy to block diatomite pores, and reduced adsorption performance, and the biodegradation speed of such organic colloid polymers is accelerated. As a result, the durability of the coating is poor and the service life is shortened. The present invention proposes a construction method for improving the adsorption performance of diatom mud for architectural decoration, thereby effectively improving the adsorption performance of diatom mud wallpaper and having good durability

Abstract

The invention provides a construction method for improving adsorptive properties of architectural decoration diatom ooze. The construction method comprises the following steps: firstly, preparing microcapsules with urea as a core material and chitosan as a capsule material, mixing and dispersing with sodium nitrite and kieselguhr, mixing prepared supported kieselguhr and a filming agent, a dye andpacking so as to obtain a kieselguhr powder material, further mixing with water and citric acid, stirring so as to obtain an ointment coating, uniformly coating a wall surface by the ointment coating, repeatedly rolling the coating with a puncture roller before complete drying, thereby achieving the purpose of improving the adsorptive properties of the architectural decoration diatom ooze. By adopting the construction method, the diatom ooze is applied to the wall surface and is repeatedly rolled by using the puncture roller, so that the microcapsules with urea inside are broken by the mechanical force, then a gas is generated through reactions, the porosity is improved, an adsorption function is improved, pollutants in the air can be adsorbed and purified by diatom ooze wallpaper, and meanwhile a microcapsule protection gas generation agent can be prevented from easy effect failure.

Description

technical field [0001] The invention relates to the field of ecological wallpaper, in particular to the construction of diatom mud wallpaper, in particular to a construction method for improving the adsorption performance of building decoration diatom mud. Background technique [0002] Diatom mud is a kind of dry powder interior wall decoration coating material prepared with inorganic gelling substance as the main bonding material and diatom material as the main functional filler. It is easy to construct and is suitable for wall and roof decoration. It is in powder form and can be painted after adding a certain proportion of water. It has the functions of eliminating formaldehyde, purifying air, adjusting humidity, releasing negative oxygen ions, fire retardant, wall self-cleaning, sterilization and deodorization, etc. It is used to replace wallpaper and latex paint. It is suitable for interior wall decoration in villas, apartments, hotels, homes, hospitals, etc. Therefore,...
