Water-based inorganic diatom ooze wall material and preparation method thereof

Abstract

The invention relates to a water-based inorganic diatom ooze wall material and a preparation method thereof. The water-based inorganic diatom ooze wall material is prepared from the following raw materials in parts by weight: 1-100 parts of diatom shale of 100-1000 meshes, 1-10 parts of graphene oxide, 0.1-5 parts of a dispersing agent special for graphene, 5-500 parts of silica sol having the solid content of 1-50%, 0.1-5 parts of a silica sol anti-cracking agent, 1-50 parts of a catalyst level nanocomposite, 0.1-5 parts of bentonite and 0.05-5 parts of cellulose. According to the water-basedinorganic diatom ooze wall material disclosed by the invention, the silica sol with mesh breathability is adopted as a binding material, the bentonite serves as a thickening agent, and the inorganicmaterial is added into the silica sol in the manner of soaking and dehydrating, so that the cracking property of the water-based diatom ooze is greatly reduced. The graphene is added to serve as a transmitting material, so that the mold resistance, weather resistance and light utilization rate of the wall material are greatly improved. Due to the addition of the catalyst level nano-photocatalyst,the addition amount of chemical organic matters is less than 1% of the overall amount. The water-based inorganic diatom ooze wall material has self-cleaning and breathable functions.

Description

technical field [0001] The invention relates to the technical field of building and household materials, in particular to a water-based inorganic diatom mud wall material and a preparation method thereof. Background technique [0002] In the field of construction and home furnishing, the construction of the wall is particularly important after the home rough is completed, 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. However, some of the current decoration materials contain organic chemical glue or adhesiv...

Problems solved by technology

And its binder is vinyl acetate or acrylic emulsion. The water-based wall material with these emulsions as the main binder has film-forming properties, and the pores of adsorption materials such as diatomaceous earth are blocked, so its functionality is blocked. It is greatly reduced, and the wall material will cause delamination and peeling off due to the aging of the coating after long-term exposure. Some moisture cannot be removed from the wall for a long time, which will lead to drumming and mildew.
