preparation example Construction
[0016] The invention provides a preparation method of a diatomite-based interior wall functional material, which comprises the following steps in turn: specifically comprises the following steps: a) diatomite, sintering aid, dispersant, water, and binder are mixed in a certain proportion After weighing and mixing, add zirconia balls and grind in a high-efficiency fast grinder, filter and dry in an electric blast constant temperature drying oven, and then calcine through crushing and electro-hydraulic sample preparation to obtain a diatomite-based functional ceramic body; b) Add a certain amount of tourmaline, sintering aid, water, dispersant, and binder to diatomite, and after ultra-fine grinding, spray the slurry onto the surface of diatomite-based functional ceramics, and dry it Calcined at low temperature, the diatomite-based interior wall functional material with environmental functional properties can be obtained.
[0017] Further, the composition of the sintering aid is ...
Embodiment
[0024] The raw materials of the diatomite-based functional ceramic body are: 850g of diatomite, 60g of kaolin, 20g of quartz, 40g of feldspar, 15g of sodium silicate, 15g of polyvinyl alcohol, and 1,000g of water; Select 8kg of 3-5mm zirconia balls, grind to D98≤10μm, then filter, dry at 105°C for 2.5 hours, press to form with a tablet press at a pressure of 45MPa, and then calcined at 1050°C for 3h, that is A diatomite-based functional ceramic body was obtained.
[0025] The raw materials of the glaze are: 73g of diatomite, 12g of tourmaline, 9g of feldspar, 2g of kaolin, 4g of quartz stone, 1g of sodium silicate, 2g of polyvinyl alcohol and 120g of water. Put each raw material into the grinder and grind until D50=4.8 μm, after passing through an 80 mesh sieve, it becomes a slurry glaze. The prepared glaze is poured on the surface of the green body, dried at 60°C for 24 hours, and calcined at 900°C for 2.5 hours to obtain diatomite-based environmentally friendly interior wal...

Abstract
The invention discloses a preparation method of a diatomite-based interior wall functional material, which comprises the following steps in sequence: a) weighing diatomite, sintering aid, dispersant, water, and binder according to a certain ratio and then mixing , add zirconia balls and grind in a high-efficiency fast grinder, filter and dry in an electric blast constant temperature drying oven, and then calcined after crushing and electro-hydraulic sample preparation to obtain a diatomite-based functional ceramic body; b) silicon A certain amount of tourmaline, sintering aid, water, dispersant, and binder are added to diatomite, and after ultra-fine grinding, the slurry is sprayed onto the surface of diatomite-based functional ceramics, dried and calcined at low temperature, that is A diatomite-based interior wall functional material with environmental functional properties was obtained. The product obtained by the invention has large specific surface area, good adsorption performance, environmental friendliness and low cost, and has good market prospect.
Description
technical field [0001] The invention relates to a preparation method of magnesium hydroxide, in particular to a preparation method of a diatomite-based interior wall functional material. Background technique [0002] Diatomaceous earth is a non-metallic mineral that is deposited on the bottom of the water from the remains of diatoms that grow in oceans or lakes. It has a unique diatom shell structure, strong adsorption, large specific surface area, and high porosity. With excellent properties such as high temperature resistance and high temperature resistance, it is widely used in the fields of chemical industry and environmental protection in modern industry. In recent years, diatomaceous earth has attracted people's attention because of its wide source, low price, and a large number of micropores below the micron level. Utilizing the characteristics of the original pores in diatomite, adding additives and low-temperature calcination process to keep the original pores and ...
