Problems solved by technology

The analysis shows that the particle size distribution in this technical scheme is not uniform, the small one is 0.3 μm, and the big one is 100 μm. Although it is possible to prepare microcrystalline bamboo charcoal and purple sand composite pottery materials with certain properties, it is difficult to obtain high-quality pottery.
This technical plan restricts the use of purple sand raw materials defined by the national standard: special clay with fine texture and high iron content, and its usage is as high as 40-60%, because purple sand ore is increasingly scarce, thus limiting its application

Embodiment 1

[0032] Preparation of pottery pellets

[0033] The average particle size of the bamboo charcoal powder, porous non-metallic mineral powder and clay is 1-10 μm. The porous non-metallic mineral adopts zeolite, and the clay adopts kaolin. The ingredients are mixed according to the ratio of 40% bamboo charcoal, 30% porous minerals, 25% clay and 5% binder. Add water and starch to the granulator to form spherical granules with a particle size of 0.5mm to 5mm, then air-dry the granules naturally for 24 hours, and then dry them in a drying oven at a temperature of 90°C for 4 hours, anaerobic sintering, and sintering temperature Keep at 1250°C for 30 minutes, and cool naturally to obtain pottery pellet products. The performance indicators of the pottery pellets are shown in Table 1.

Embodiment 2

[0035] Preparation of honeycomb pottery

[0036] The average particle size of the bamboo charcoal powder, porous non-metallic mineral powder and clay is 1-10 μm. The porous non-metallic mineral adopts zeolite, and the clay adopts attapulgite. Mix ingredients according to the ratio of 35% bamboo charcoal, 45% porous minerals, 18% clay and 2% binder. The process of preparing microcrystalline bamboo charcoal composite honeycomb pottery is as follows: add water, dextrin smelt, and stale, put the mud into the molding mold and extrude it, let it dry naturally for 24 hours, then put it in a constant temperature drying box, and adjust the temperature to 90°C Dry for more than 4 hours; then put it into a sintering furnace for anaerobic sintering at a sintering temperature of 1200° C., keep for 30 minutes, and naturally cool to obtain a honeycomb ceramic product. The performance index of honeycomb pottery is shown in Table 2.

Embodiment 3

[0038] Preparation of pottery slabs

[0039] The average particle size of the bamboo charcoal powder is 20-40 μm, and the average particle size of the porous non-metallic mineral powder and clay is 40-70 μm. The porous non-metallic mineral adopts volcanic slag, and the clay adopts bentonite. The ingredients are mixed according to the ratio of 25% bamboo charcoal, 45% porous minerals, 28% clay and 2% binder. Add an appropriate amount of water and gum arabic to make granules with a particle size of 0.5-2 mm. Then fill the granulated material into the mold, press 120MPa pressure to form decorative ceramic plates with different appearances, put them into a drying oven at 90°C to dry, then engrave, and finally carry out anaerobic sintering. The sintering temperature was 1300° C. and kept for 45 minutes. Natural cooling to obtain flat pottery products. The performance indicators of the pottery slabs are shown in Table 3.

Abstract

The invention provides a microcrystal and bamboo charcoal composite pottery material, which is composed of the following components in percentage by weight: 20 to 50% of bamboo charcoal powder, 30 to 60% of porous non-metal mineral powder, 10 to 30% of clay, and 2 to 5% of binder. The porous non-metal ore is used to replace the purple sand, the raw material resources are greatly enlarged, and the cost is reduced. Moreover, the different porous non-metal ores have different chemical components and colors, thus the produced potteries are suitable for various occasions and environments, more specially, light color or even white potteries can be prepared from the provided composite pottery material. Compared to the potteries produced by the prior art, the potteries prepared from the provided microcrystal and bamboo charcoal composite pottery material have more pores and micro holes, a larger specific area, and a better water-absorbing and gas-absorbing performance. The invention also relates to a preparation method of the provided microcrystal and bamboo charcoal composite pottery material.

Description

technical field [0001] The invention relates to a novel pottery material, in particular to a novel ecological environment functional pottery material, more specifically to a microcrystalline bamboo charcoal composite pottery material and a preparation method thereof. Microcrystalline bamboo charcoal composite pottery material is a composite pottery material with high porosity, good adsorption performance, low bulk density, low firing shrinkage, high flexural strength, negative ion release and far-infrared radiation functions. Background technique [0002] Bamboo charcoal has a rich honeycomb microporous structure. This microporous structure makes bamboo charcoal have a large specific surface area and excellent adsorption function. It also has special effects such as electromagnetic shielding, radiating far-infrared rays, generating negative ions, and increasing water alkalinity. It is used for moisture absorption, deodorization, disinfection, sterilization, heat storage, hum...
