Problems solved by technology

Now people have higher and higher requirements for decoration, and the wall materials used are more and more expensive, but most of the current decoration wall materials contain organic chemical glue or other adhesives, which contain harmful pollutants to the human body, seriously threatening People's health, because of decoration pollution, frequent occurrence of physical discomfort such as dizziness and nausea, which seriously threatens the life safety of residents
In order to meet people's needs, some wall materials that can absorb and purify harmful substances in the air have appeared on the market, but in order to be bonded to the wall, binders such as lime cement and latex powder are often added. Combined with porous materials such as diatomaceous earth, it will block the few breathing holes, reduce the respiration of diatom mud wall materials, and reduce the ability to absorb formaldehyde and water vapor

Abstract

The invention discloses a preparation method of diatom mud wall materials with hygroscopic property, respiratory property and antibacterial property. The method comprises the following steps: firstly soaking diatom mud wall material powders in an acidic or alkaline wall material corrosion liquid for corrosion, and soaking in a sodium chloride solution; then adding zinc oxide nanoparticles; and finally oven-drying to obtain the final product of diatom mud wall material. The diatom mud wall material powder is endowed with pores of 2-5 nanometers by means of chemical reactions. The method provided by the invention can improve the hygroscopic property, respiratory gaps and antibacterial property of diatom mud wall materials.

Description

technical field [0001] The invention relates to the technical field of building and household materials, in particular to a preparation method of a diatom mud wall material with strong hygroscopicity, breathability and antibacterial properties. Background technique [0002] As we all know, the construction of the wall is particularly important after the completion of the rough home furnishing in the field of construction and home furnishing, so that there is a choice of wall materials. "Wall material", as the name implies, refers to the material related to the wall painting construction and the ordinary mortar surface. Nowadays, people not only have to face possible pollution in public places, but also have to face pollution from private individuals and even the human body itself. Therefore, in an era when various cancer symptoms are increasing, the "green revolution" has become an inevitable choice to ensure ecological balance and ecological stability. Now people have hig...
