Problems solved by technology

[0008] At present, diatom mud, which is widely used for interior decoration, has problems such as low strength, easy to drop powder, and easy to crack. However, the traditional technology of adding organic colloidal substances to improve performance is easy to block the pores of diatom mud and reduce the adsorption performance. And then affect the durability and service life of diatom mud coating

Abstract

The invention relates to the field of a decoration material, and discloses durable diatom ooze decoration wall material powder and a preparation method thereof. Diatomite and a powdery foaming agent are added into a powder modifier to be mixed; water-soluble emulsion containing graphene is sprayed and deposited on the surface of diatomite loaded with the foaming agent; surface modified diatomite is obtained and is used for preparing diatom ooze wall material powder. Compared with traditional diatom ooze, the prepared diatom ooze wall material powder has the advantages that a graphene-containing diaphragm is coated at the surface for separation; the protection effect is achieved on pores of the diatomite; meanwhile, the foaming agent is loaded in the pores and foams to generate gas during the construction; the problem of pore blockage is effectively solved; the adsorption effect is improved; meanwhile, the graphene is uniformly dispersed, so that powder falling and cracking cannot easily occur; the durability is obviously improved; the service life is prolonged.

Description

technical field [0001] The invention relates to the field of decorative materials, and discloses a durable diatom mud decorative wall material powder and a preparation method thereof. Background technique [0002] In recent years, more and more attention has been paid to the impact of interior decoration materials on air quality. At present, various decoration materials, such as paints and paints, contain a large amount of harmful substances (formaldehyde, benzene, ammonia, volatile organic compounds, etc.) that will cause indoor air pollution. air pollution. Therefore, green environment-friendly decorative materials are favored by people, and the development of diatom mud has received extensive attention. [0003] Diatom mud wall material is a kind of natural and environmentally friendly wall decoration paint, which is easy to construct and is suitable for wall and roof decoration. It is in powder form and can be used for painting after adding a certain proportion of water...
