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.

preparation example Construction

[0037] The present invention provides a kind of preparation technology of diatom gypsum wall material, and described preparation technology comprises the following steps:

[0038] Step 1, using the first raw material and water to prepare diatom-based gypsum boards;

[0039] Step 2, mixing the second raw material with water, optionally adding natural plant binding material, preferably stirring evenly, to prepare the binding agent;

[0040] Step 3. Apply the adhesive prepared in step 2 to one side of the diatom gypsum board prepared in step 1 or to the wall to be pasted, and then paste the board to the wall to form a diatom gypsum wall material .

[0041] According to a preferred embodiment of the present invention, in step 1 and step 2, both the first raw material and the second raw material contain the following components in a weight ratio: 10-60 parts by weight of diatom powder, 10-80 parts by weight of gypsum powder.

[0042] In a further preferred embodiment, in step 1 ...

Embodiment approach

[0087] According to a preferred embodiment of the present invention, the particle size of the hollow glass microspheres is 20-200 μm.

[0088] In a further preferred embodiment, the particle size of the hollow glass microspheres is 50-100 μm.

[0089] In a further preferred embodiment, the particle size of the hollow glass microspheres is 60-80 μm.

[0090] Among them, the particle size of the hollow glass microspheres should not be too large, otherwise it will affect the appearance of the wall. Too small particle size will cause unnecessary waste of cost.

[0091] According to a preferred embodiment of the present invention, the particle size of the opal powder is 100-10000 mesh, preferably 200-5000 mesh, more preferably 500-2000 mesh.

[0092] According to a preferred embodiment of the present invention, the pore diameter of the opal powder is 5-50 nm, preferably 10-40 nm, more preferably 15-35 nm.

[0093] Among them, the pore size of opal powder is very small, even smal...

Embodiment 1

[0151] Use a 3D powder printer to print out a mold template with a certain geometric pattern, and then reverse it into a silica gel mold; take 100g of calcined first-grade diatomite, 800g of calcined first-grade gypsum powder and 50g of negative ion powder, add them to the mixer, and fully stir for 20min. Add 850g of water and stir evenly to obtain the plate material; spray the mold release agent on the silica gel mold, then fill the obtained plate material into the silica gel mold, flatten and compact it, and then use the glass fiber mesh cloth that has been cut in advance according to the size of the plate Set the surface (that is, the back side of the board), compact and flatten it again; put it into a drying oven for drying, then demold and air-dry to obtain the diatom-based gypsum board.

[0152] Take 100g of calcined first-grade diatomite, 800g of calcined first-grade gypsum powder, 20g of gum arabic powder and 50g of negative ion powder respectively, add them to a blende...

Abstract

The invention discloses a preparation process of a diatoms gypsum wall material, wherein the preparation process comprises the following steps: 1, adopting a first raw material and water as raw materials, and preparing a diatoms gypsum board; 2, mixing a second raw material with water, and optionally, adding a natural plant adhesive material, to prepare an adhesive; and 3, coating one face of the diatoms gypsum board prepared in the step 1 with the adhesive prepared in the step 2 or coating a to-be-pasted wall body with the adhesive, then pasting the board onto the wall body, and thus forming the diatoms gypsum wall material. The diatoms gypsum wall material prepared by the invention is an environment-friendly type raw material, cannot release any harmful substances, also can fully absorb indoor formaldehyde, benzene and other harmful substances, and maintains indoor air fresh; and moreover, the diatoms gypsum wall material is easy to construct, and the damage is easy to repair.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a preparation process of diatom-based gypsum wall materials. Background technique [0002] With the increasing expansion of the wall material market, the application of decorative wall materials is becoming more and more extensive, and people's requirements for wall materials are also getting 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. Full attention to environmental protection. [0003] Most of the wall materials for interior decoration currently on the market have organic chemical properties, and generally contain volatile substances such as formaldehyde, benzene and ammonia that are harmful to human health. And most of the commercially available wall materials adopt paste and then smear on the wall, but the construction speed of this method is slow, and it is more restrict...
