Embodiment 1

[0068] Take kaolin 360g, bentonite 30g, potassium feldspar 110g, albite 70g, anorthite 80g, quartz 70g, pyrochlore 60g, fluorite 70g, talcum powder 10g, mullite 60g, waste porcelain powder 50g, Jiepai Mud 30g, sintering aid 55g and fluorescent powder 100g.

[0069] Put the above raw materials into the mixing bucket, use a mixer to mix the raw materials evenly, and stir for about five minutes. After mixing evenly, add 600g of water to the raw materials being stirred, and slowly add water while stirring, which can increase the mixing uniformity of the mud raw materials. After stirring, add 14g of plasticizer sodium humate, 8g of soluble starch, 6g of polyvinyl alcohol and 12g of carboxymethyl cellulose, and continue stirring for 3 minutes. After completion, the water content of the mud is about 26%. After the stirring is completed, add 7 g of decoagulant sodium silicate, 6 g of sodium carbonate and 12 g of tannic acid, and continue stirring until the water content is about 25%....

Put the above raw materials into the mixing bucket, use a mixer to mix the raw materials evenly, and stir for about five minutes. After mixing evenly, add 600g of water to the raw materials being stirred, and slowly add water while stirring, which can increase the mixing uniformity of the mud raw materials. After stirring, add 14g of plasticizer sodium humate, 8g of soluble starch, 6g of polyvinyl alcohol and 12g of carboxymethyl cellulose, and continue stirring for 5 minutes. The water content after completion is about 25%. After the stirring is completed, add 7 g of decoagulant sodium silicate, 6 g of sodium carbonate and 12 g of tannic acid, and continue stirring for 5 minutes. Finally, add 4.5g of floccula...

Embodiment 3

[0073] Embodiment 3: get kaolin 360g, bentonite 30g, potassium feldspar 110g, albite 70g, anorthite 80g, quartz 70g, pyrochlore 60g, fluorite 70g, talcum powder 10g, mullite 60g, waste porcelain powder 50g, Jiepai mud 30g, sintering aid 55g and fluorescent powder 150g. Put the above raw materials into the mixing bucket, use a mixer to mix the raw materials evenly, and stir for about five minutes. After mixing evenly, add 600g of water to the raw materials being stirred, and slowly add water while stirring, which can increase the mixing uniformity of the mud raw materials.

Abstract

The invention relates to the field of a ceramic material and especially relates to an illuminant ceramic mud composition for a mud extruding process. The illuminant ceramic mud composition comprises the following components in a weight ratio: kaoline, bentonite, potassium feldspar, albite, anorthite, quartz, pyrochlore, fluorite, talcum powder, mullite, waste ceramic powder, Jiepai mud, a plasticizer, a liquefaclent, a flocculant, a brightening agent, a high temperature protective agent, an anti-cracking agent, a wetting agent, a tackifier, a rare earth trichromatic phosphor, a sintering additive and water. The illuminant ceramic mud composition prepared according the formula and preparation method provided by the invention has magnificent fluorescence characteristic and light transmittance performance. The illuminant ceramic mud has higher liquidity than that of common mud, difficultly blocks a sprayer in a forming process and has higher plasticity than that of common mud, and meanwhile, a green body is difficult to deform in the forming process.

Description

technical field [0001] The invention relates to the field of ceramic materials, in particular to a luminescent ceramic mud material composition for mud extrusion and a preparation method thereof. Background technique [0002] Nowadays, individual ceramics cover a wide range. However, ceramics printed by rapid prototyping technology lack individuality, so their value is not high, and there are no ceramics with fluorescent and light-transmitting properties on the market. Contents of the invention [0003] The invention provides a luminous ceramic mud composition for mud extrusion method and a preparation method thereof, so as to solve the above-mentioned technical problems. [0004] In order to achieve the above object, the technical solution of the present invention is achieved in that: [0005] A luminescent ceramic mud composition for the mud extrusion method, by weight ratio, comprising: [0006] Kaolin 16.8-18.5% [0007] Bentonite 1.1-1.6% [0008] Potassium felds...
