Embodiment 1

[0029] The first step, sepiolite pretreatment

[0030] The sepiolite raw ore is processed through ore dressing, washed with water, dried naturally, crushed into 10mm particles by a tooth crusher, and then processed by jet mill to obtain sepiolite mineral nanofibers with an average particle size of 7 μm;

[0031] The second step, the production of blanks and blanks

[0032] 30% bone meal, 15% Laiyang soil, 20% albite feldspar, 5% Datong soil, 8% Fangzi soil and 20% Longyan soil are used as raw materials in proportion by weight to form a billet, and the billet is prepared by weight ratio: Ball: water = 1: 2: 1 is put into the ball mill and added to the water ball mill, and after the raw material ball milling of the ratio is 60 μm, add 2% of the sepiolite mineral nanofiber obtained by the first step of sepiolite pretreatment, after adding Continue ball milling and mixing for 2 hours, then sieve through sieves with mesh size of 120 mesh, 180 mesh and 200 mesh for three times, rem...

Embodiment 2

[0036] The first step, sepiolite pretreatment

[0037] The sepiolite raw ore is processed through ore dressing, washed with water, dried naturally, crushed into 15mm particles by a tooth crusher, and then processed by jet mill to obtain sepiolite mineral nanofibers with an average particle size of 7 μm;

[0038] The second step, the production of blanks and blanks

[0039] Raw materials are prepared by proportioning 35% of bone meal, 12% of Laiyang soil, 17% of albite, 6% of Datong soil, 10% of Fangzi soil and 15% of Longyan soil to form a billet according to the weight percentage, and put the billet into a ball mill and add water for ball milling. After ball milling the proportioned raw materials to a particle size of 70 μm, add 5% of sepiolite mineral nanofibers obtained from the first step of sepiolite pretreatment, continue ball milling and mixing for 2.5 hours after adding, and then use sieves with mesh sizes of 120 mesh , 180 mesh and 200 mesh sieves were sieved three t...

Embodiment 3

[0043] The first step, sepiolite pretreatment

[0044] The sepiolite raw ore is processed through ore dressing, washed with water, dried naturally, crushed into 20mm particles by a tooth crusher, and then processed by a jet mill to obtain sepiolite mineral nanofibers with an average particle size of 7 μm;

[0045] The second step, the production of blanks and blanks

[0046] Raw materials are prepared by proportioning 40% of bone powder, 9% of Laiyang soil, 15% of albite, 8% of Datong soil, 5% of Fangzi soil and 15% of Longyan soil by weight to form a billet, and the billet is put into a ball mill and added with water for ball milling. After ball milling the proportioned raw materials to a particle size of 80 μm, add 8% of sepiolite mineral nanofibers obtained from the first step of sepiolite pretreatment. After adding, continue ball milling and mixing for 3 hours, and then use sieves with mesh sizes of 120 mesh , 180 mesh and 200 mesh sieves were sieved three times, iron rem...

Abstract

The invention provides bone china and a preparation method thereof and relates to chain forming products characterized by components. The bone china is sepiolite mineral nanofiber toughened bone china and comprises the following components in percentage by weight: bone powder 30-40%; Laiyang soil 9-15%; albite 15-20%; Datong soil 5-8%; Fangzi soil 5-10%; Longyan soil 15-20%; and sepiolite mineral nanofiber 2-8%. The preparation method comprises the following steps: treating sepiolite by a jet mill to obtain the sepiolite mineral nanofiber which is used as raw materials of blank materials by required weight percent; and preparing the raw material into the blank materials by adding water for ball-milling, sieving, deironing and aging and rotting; carrying out blank forming, drying and fettling on the blank materials to obtain a blank body; and then porcelainizing to prepare the sepiolite mineral nanofiber toughened bone china. The bone china has higher toughness, simple preparation process and low preparation cost.

Description

technical field [0001] The technical proposal of the invention relates to a ceramic molded product characterized by its composition, specifically a bone china and its preparation method. Background technique [0002] Bone china has been used by nobles in various countries for a long time because of its unique shape, concise and lively texture, and white and delicate texture. It is currently recognized as a high-grade porcelain in the world. It is a kind of soft porcelain made mainly of calcined bone powder, with some mineral raw materials such as clay, feldspar and quartz added, and fired by high-temperature plain firing and low-temperature glaze firing for secondary firing. CN200810218702.1 discloses a bone china and its production process; CN200810147461.6 discloses a lead-free bone china and its preparation method, the bone china is made of bovine bone carbon, pig bone carbon, Datong sandstone, Composed of quartz, feldspar, kaolin, cooked kaolin and bentonite; CN 9811659...
