Embodiment 1

[0030] The first step, attapulgite powder pretreatment

[0031] Dry-mill the attapulgite powder with a ball mill and pass it through a 60-mesh sieve to remove some granular impurities to obtain attapulgite mineral nanofiber powder. The fiber rod length is about 0.5-1.5 μm, and the radial width is about 15- 25nm.

[0032] The second step, the preparation of green body mud

[0033] Weigh each mineral raw material by weight percentage: Tangshan Zimujie 3%, Henan Qinyang clay 14%, washed kaolin 14%, Guangdong ball clay 10%, Zhangcun clay 13%, Qinhuangdao porcelain stone 10%, Liaoning Faku porcelain clay 9%, 5% of Chengde paddock clay, 15% of feldspar, 3% of talc, and 4% of waste porcelain powder to form the body material. The ratio of the body material and grinding balls is 1:2 by weight. The diameters are 15.50mm and 10.50mm respectively, the ratio of large and small balls is 2:1, then add 0.5% water glass of the mass of the green body material and 0.25% of the alkali surface o...

Embodiment 2

[0040]During the second step in Example 1, the step of adding attapulgite mineral nanofiber powder (other material composition and quality remain unchanged) and the step of continuing ball milling and mixing are cancelled, and other operations are carried out in sequence, and finally in the fourth step, the obtained A sanitary ceramic green body added with attapulgite nanofiber powder.

[0041] The mechanical properties of the obtained ceramic body are: the bending strength reaches 55MPa, and the fracture toughness reaches 21.20MPa m 1 / 2 , The water absorption rate is 0.22%. Among them, the bending strength of the sanitary ceramic body is tested according to the national standard GB / T 6569-2006 / ISO14704: 2000; the fracture toughness of the sanitary ceramic body is tested according to the international standard ISO 23146-2012; the water absorption of the sanitary ceramic body is tested according to the national standard Standard GB / T 3810.3-2016 / ISO 10545-3:1995 to test.

Embodiment 3

[0044] The first step, attapulgite powder pretreatment

[0045] Dry-mill the attapulgite powder with a ball mill and pass it through a 50-mesh sieve to remove some granular impurities to obtain attapulgite mineral nanofiber powder. The fiber rod length is about 0.5-1.5 μm, and the radial width is about 15- 25nm.

[0046] The second step, the preparation of green body mud

[0047] Weigh each mineral raw material by weight percentage: Tangshan Zimujie 2%, Henan Qinyang clay 13%, washed kaolin 13%, Guangdong ball clay 12%, Zhangcun clay 13%, Qinhuangdao porcelain stone 11%, Liaoning Faku porcelain clay 7%, Chengde Weichang clay 6%, feldspar 15%, talc 5%, and waste porcelain powder 3% to form the green body material. The weight ratio of the green body material and grinding balls is 1:2, and the size of the grinding balls The diameters are 15.50mm and 10.50mm respectively, the ratio of large and small balls is 2:1, then add 0.5% water glass of the mass of the green body material ...

Abstract

The invention discloses an attapulgite strengthened and toughened sanitary ceramic green body and a preparing method thereof. The sanitary ceramic green body is prepared from a green body material andattapulgite mineral nanofibers, wherein the attapulgite mineral nanofibers account for 1-4% of the mass of the green body material. The green body material is prepared from 1-6% of knar clay, 8-16% of Qinyang clay, 9-16% of kaolin, 9-16% of ball clay, 9-16% of Zhangcun clay, 9-16% of porcelain stone, 4-11% of porcelain clay, 4-11% of clay, 14-21% of feldspar, 1-6% of talcum and 1-6% of waste porcelain powder. The developed strengthened and toughened sanitary ceramic green body containing the natural nanofibers has the advantages of being simple in process, low in cost, capable of bringing small environmental loads and the like.

Description

technical field [0001] The technical solution of the invention relates to a ceramic molded product characterized by composition, specifically an attapulgite toughened sanitary ceramic body and a preparation method thereof. Background technique [0002] For hundreds of millions of consumers, sanitary ceramics are the representative of their warm homes. With the gradual improvement of people's living standards, sanitary ceramics have gradually entered the homes of ordinary people, but sanitary ceramics are a kind of complex shape, large size and weight. Ceramic products, which means that the sanitary ceramics industry consumes huge energy and resources. In order to prevent cracking and damage during handling, the green body will be thickened, which will lead to the characteristics of large volume and high weight of sanitary ceramics. , the energy consumption will also increase, and the production cost will also increase. Today, when resources and energy are facing depletion, ...
