Problems solved by technology

Moreover, most of the commercially available wall materials are in the form of paste and then applied on the wall. However, this method has a slow construction speed and is more restricted by the technical skills of the workers, and there are disadvantages that it is not easy to damage and repair during use.

Embodiment 1

[0166] Example 1 Preparation of diatom plate

[0167] Use a 3D powder printer to print a mold template with a certain geometric pattern, and then reverse it into a silicone mold;

[0168] Take 100g of calcined first-grade diatomite, 800g of calcined first-grade gypsum powder and 50g of negative ion powder, respectively, add them to a mixer, fully stir for 20 minutes, add 850g of water, and stir evenly to obtain board raw materials;

[0169] Spray the release agent on the silicone mold, and then fill the obtained sheet material into the silicone mold to smooth and compact, and then set it on the surface (ie the back of the sheet) with a glass fiber mesh cloth that has been cut according to the size of the sheet in advance. Smoothing and compaction to enhance the tensile and fracture resistance of the board;

[0170] Put it into a drying box for drying, then demould and air dry to obtain the diatom plate.

Embodiment 2

[0171] Example 2 Preparation of diatom plate

[0172] Use a 3D powder printer to print a mold template with a certain geometric pattern, and then reverse it into a steel mold;

[0173] Take 200g of calcined first-grade diatomaceous earth, 600g of calcined first-grade gypsum powder, 40g of anion stimulating substance, 75g of opal powder and 15g of hollow glass beads, add them to a mixer, stir well for 20min, add 850g of water, and stir evenly to obtain a plate raw material;

[0174] Spray the release agent on the steel mold, and then fill the obtained sheet material into the silicone mold to smooth and compact, and then set it on the surface (ie the back of the sheet) with the glass fiber mesh cloth that has been cut according to the sheet size in advance. Smoothing and compaction to enhance the tensile and fracture resistance of the board;

[0175] Put it into a drying box for drying, then demould and air-dry to obtain the diatom plate.

Abstract

The invention discloses a diatom board powder and a method for preparing a diatom board with the same. The diatom board powder is prepared from diatom powder and gypsum powder, wherein due to the diatom powder, the diatom board powder has high adsorption performance and can effectively adsorb formaldehyde, benzene and other hazardous substances in air, and meanwhile the diatom board powder can release negative ions. The diatom board powder is further prepared from a negative ion excitation material. The diatom board powder can be prepared into the diatom board in a given shape through the 3D printing technology or the computer sculpting technology, the diatom board is prepared from environment-friendly raw materials and will not release any hazardous substance, and besides, the diatom board can fully adsorb formaldehyde, benzene and other hazardous substances in a room and keep air in the room fresh; construction of the diatom board is easy, and damage repair is easy.

Description

Technical field [0001] The invention relates to the field of building materials, in particular to a diatom plate powder used for wall materials and the preparation of diatom plate powder by using the diatom plate powder. Background technique [0002] With the ever-expanding wall material market, the application of decorative wall materials has become more and more extensive, and people’s requirements for wall materials have become higher and higher. From the single point of view of beauty in the past, it has changed to the overall comfort and safety of the indoor environment. Comprehensive attention to environmental protection. [0003] At present, most of the indoor decoration wall materials sold on the market have organic chemical properties and generally contain volatile substances such as formaldehyde, benzene and ammonia that are harmful to human health. In addition, most of the commercially available wall materials are paste-like and then applied to the wall. However, this m...
