Embodiment 1

[0031] An environmentally friendly diatom mud is characterized in that it is composed of the following components in parts by weight: 30 parts of modified diatomite, 0.5 parts of black phosphorus quantum dots, 8 parts of palygorskite powder, 6 parts of illite powder, surface 10 parts of modified Ti-Nd-O, 0.3 parts of hydroxypropyl methylcellulose, 3 parts of sodium polyacrylate superabsorbent resin, and 25 parts of water.

[0032] The preparation method of the surface modified Ti-Nd-O comprises the following steps:

[0033] ⅠAdd chemically pure titanium chloride and rubidium nitrate to ethanol, stir ultrasonically for 0.5h, then slowly add sodium acetate, and stir vigorously for 1h, then transfer the solution to a polyvinyl fluoride-lined hydrothermal reaction kettle, Reaction at 180°C for 15h. Take out the reaction kettle, wash the reaction system repeatedly with deionized water and absolute ethanol after cooling, and finally dry it in a vacuum oven at 70°C for 18 hours, the...

Embodiment 2

[0040] An environmentally friendly diatom mud is characterized in that it is composed of the following components in parts by weight: 35 parts of modified diatomite, 1 part of black phosphorus quantum dots, 9 parts of palygorskite powder, 6.5 parts of illite powder, surface 12 parts of modified Ti-Nd-O, 0.4 parts of polyvinyl alcohol, 4 parts of starch-grafted acrylate superabsorbent resin, and 27 parts of water.

[0041] The preparation method of the surface modified Ti-Nd-O comprises the following steps:

[0042] ⅠAdd chemically pure titanium nitrate and rubidium sulfate to ethanol, stir ultrasonically for 0.7h, then slowly add sodium acetate, and stir vigorously for 1.2h, transfer the solution to a polyvinyl fluoride-lined hydrothermal reaction kettle, Reaction at 190°C for 17h. Take out the reaction kettle, wash the reaction system repeatedly with deionized water and absolute ethanol after cooling, and finally dry it in a vacuum oven at 73°C for 20 hours, then burn it in ...

Embodiment 3

[0049] An environmentally friendly diatom mud is characterized in that it is composed of the following components in parts by weight: 40 parts of modified diatomite, 1.5 parts of black phosphorus quantum dots, 10 parts of palygorskite powder, 7 parts of illite powder, surface 15 parts of modified Ti-Nd-O, 0.45 parts of hydroxypropyl methylcellulose, 4.5 parts of cross-linked hydroxyethyl cellulose grafted acrylamide polymer superabsorbent resin, and 30 parts of water.

[0050] The preparation method of the surface modified Ti-Nd-O comprises the following steps:

[0051] Ⅰ Add chemically pure titanium sulfate and rubidium chloride to ethanol, stir ultrasonically for 0.7h, then slowly add sodium acetate, and stir vigorously for 1.5h, then transfer the solution to a polyvinyl fluoride-lined hydrothermal reaction kettle, Reaction at 200°C for 18h. Take out the reaction kettle, wash the reaction system repeatedly with deionized water and absolute ethanol after cooling, and finally...

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to an environment-friendly diatom mud and a preparation method thereof. Background technique [0002] In recent years, with the development of social economy and the improvement of people's living standards, the understanding of environmental issues has gradually deepened, the desire to improve the home environment has become more and more urgent, and the environmental protection of decorative materials has become more and more important. However, artificial boards such as plywood and decorative panels on the market, adhesives such as urea-formaldehyde resin, phenolic resin, and formaldehyde resin, and decorative materials such as various decorative impregnation materials, wall coatings, wallpapers, floors, and chemical fiber carpets are inseparable. Open formaldehyde, the formaldehyde contained in the decorative material itself, and the harmful gases such as formaldehy...
