Embodiment 1

[0025] Take 88g of bright green pigment, 3g of brown-black pigment, and 9g of yellow-brown pigment, add them to 1000ml of water and mix them evenly to obtain a color paste. 200 g of porous silica gel particles were added to the prepared color paste while discrete, continued to be discrete for 30 min, and then precipitated for 2 h. After the slurry is water-layered, the precipitation material in the lower part is filtered, dehydrated, dried and ground into powder materials below 40 μm, and then the powder materials are coated on a base cloth and dried to obtain diatom mud natural composite wallpaper. Among them, the silica gel particles selected in this example are porous silica gel particles with a particle size of 50 μm. Since the adsorption of diatom mud is realized by nano-pore adsorption, and the mineral powder is bound to achieve the purpose of uniform dyeing. Powder below 325 mesh, but too fine powder can easily block the micropores of diatom mud, resulting in a decrease...

Embodiment 2

[0028] Take 70g of yellow-brown pigment, 12g of orange-red pigment, and 18g of orange, add them into 1000m1 water and mix them uniformly to obtain a color paste. 400 g of porous silica gel particles were added to the prepared color paste while discrete, and the particles were further dispersed for 40 min and then precipitated for 2.5 h. After the slurry is water-layered, the precipitation material in the lower part is filtered, dehydrated, dried and ground into powder materials below 40 μm, and these colors are applied on a base cloth and dried to obtain diatom mud natural composite wallpaper. Among them, the silica gel particles selected in this example are porous silica gel particles with a particle size of 65 μm. Since the adsorption of diatom mud is realized by nano-pore adsorption, and the mineral powder is bound to achieve the purpose of uniform dyeing. Powder below 325 mesh, but too fine powder can easily block the micropores of diatom mud, resulting in a decrease in ad...

Embodiment 3

[0031] Take 55g of blue pigment, 25g of red pigment and 20g of sapphire blue, add them to 1000m1 of water and mix them evenly to obtain a color paste. Take 800g of porous silica gel particles and add them to the prepared color paste while dispersing, continue to mix for 50 minutes, and then settle for 3 hours. After the slurry is water-layered, the precipitation material in the lower part is filtered, dehydrated, dried and ground into powder materials below 40 μm, and the powder materials are coated on a base cloth and dried to obtain the diatom mud natural composite wallpaper. The silica gel particles selected in this embodiment are porous silica gel particles with a particle size of 90 μm. Since the adsorption of diatom mud is achieved by nano-pore adsorption, and the mineral powder is bound to achieve the purpose of uniform dyeing, the color is bound to be processed into Powder below 325 mesh, but too fine powder can easily block the micropores of diatom mud, resulting in a...

Abstract

The invention discloses a preparation method of diatom-ooze composite pigment. The preparation method disclosed by the invention has the advantages that a proper proportion for the pigment is given, and has a guidance value for practical production, so that the searching time is omitted, the blended color is pure, and is suitable for aesthetic points of common people; in addition, proper pigment particle diameter and silica-gel particle diameter are selected, so that a prepared mixed diatom-ooze coating is uniform in color.

Description

technical field [0001] The invention relates to the technical field of diatom mud coating, in particular to a preparation method of a diatom mud composite pigment. Background technique [0002] Diatom mud is an emerging decoration material for indoor pollution removal in recent years. Its main function is to absorb harmful substances such as formaldehyde. There are more than 40 kinds reaching 100 kinds, so the color of diatom mud has always been a difficult problem for people in the industry. [0003] At present, there are two main ways to color diatom mud. Among them, one is the on-site color matching method, which is to prepare the toner in advance, that is, the red, yellow, blue, green, brown and black powders are first weighed on the spot, and when discrete, simply add white diatoms and mix them in to achieve color matching. Purpose, the disadvantage of this method is that the operation is complicated and the color is unstable. It is necessary to calculate the required...
