Description
Technical field
The present invention relates to domestic ceramics technical field, and in particular to a kind of high daily bone china of whiteness and preparation method thereof.
Background technology
China industry is high energy-consuming industry, along with the high speed development of china industry, and the problem of it consumes energy serious is also increasingly
It is prominent.According to statistics, in ceramic industry, China's energy consumption is 3.1 times of world average level, is OECD (economic cooperation and development
Tissue) 4.3 times of countries and regions, it is even more 9 times of Japan.Need to consume substantial amounts of kaolin etc. every year during ceramic making
Raw material, the resource such as kaolin faces the situation very severe of exhaustion.The concern protected with Environmental, it is reasonable to resource
The attention utilized, china industry structural adjustment becomes very urgent.At the same time, with the development of the society, people's daily life
The increasingly raising of level, domestic ceramics is the necessity of life staying idle at home again, consumer have to appearance such as whiteness of household china etc. compared with
High requirement, while also focusing on the internal performance of household china, the requirement of such as rupture strength and heat endurance.
Therefore need to sum up superior technique scheme to reduce the consumption of rare raw material, reduce energy consumption, reduce cost,
Whiteness, rupture strength and the heat endurance of daily porcelain products are improved simultaneously, are improved product quality and cost performance, are met consumer
To the demand of daily porcelain products.
Bone china is the porcelain being made using bone ash as main flux, and its whiteness is high, and translucence is good, is high-grade porcelain
And decoration porcelain.But the production of current China bone china is not still universal, and the quality of production is unsatisfactory, the bone china for production
Slurry thixotropy is poor, intensity is relatively low, the problems such as easily cracking, the integrated quality of strong influence ceramics.
The content of the invention
For above-mentioned problem, the present invention proposes a kind of daily bone china of high whiteness and preparation method thereof, passes through
The step such as mixing, heating, precalcining, broken, ball milling, sintering is made, with good thermoplasticity and heat endurance, processability
Good, obtained product appearance flat smooth, mechanical strength and translucency are obviously improved, and whiteness is up to 82%, and yield rate is reachable
More than 95%, effectively increase the integrated quality of household china.
In order to realize above-mentioned purpose, the present invention uses following technical scheme：
A kind of daily bone china of high whiteness, including following percentage composition component are made：Kaolin 21-24%, feldspar 7-
11%th, quartz 10-15%, sepiolite fibre 1.3-2.6%, shepardite 0.3-1.2%, diatomite 2-5%, sodium alginate
0.48-0.65%, dispersant 0.15-0.25%, bone ash powder surplus.
It is preferred that, in addition to crop starch 0.1-2%, the crop starch is selected from rice starch, farina, corn
One or more compositions in starch, wheaten starch.
It is preferred that, amylose accounts for 20-40wt% in the crop starch.
It is preferred that, the dispersant is mass ratio 2:3 talcum powder and precipitated calcium carbonate.
It is preferred that, the high daily bone china of whiteness, preparation process is as follows：
1) raw material is weighed in mass ratio, water filling is mixed thoroughly to scattered paste shape into diatomite, appropriate temperature is injected into sodium alginate
Water is stirred to dissolving, standby；
2) sodium alginate soln after dissolving is added in scattered paste shape diatomite under agitation, 60 DEG C of insulated and stirreds
Sepiolite fibre, is then added thereto by 20-30min again, is warming up to 92 ± 2 DEG C, is incubated 1.6-2h, is freeze-dried to obtain solid powder
Material, it is standby；
3) by bone ash powder under the conditions of 100 DEG C freeze-day with constant temperature 1h, after taking-up carry out segmentation precalcining processing, obtain aggregate, it is standby
With；
4) feldspar, quartz, shepardite are first crushed into 1-3h in kibbler roll, a magnetic separation is carried out after taking-up, then
It is blended with solid powder, aggregate and other surplus stocks, is placed in after ball milling 6-7h in ball mill, taking-up and carries out secondary magnetic separation,
Batch mixing is obtained, it is standby；
5) batch mixing is injected in mould and forms base substrate, sent into after drying in tunnel cave and sinter 40- under the conditions of 1200 ± 5 DEG C
60min.
It is preferred that, step 1) in warm water temperature be 38-40 DEG C.
It is preferred that, step 3) in segmentation precalcining processing be specially first 1080 ± 10 DEG C DEG C calcine 1-2h, then heat up
To 1220 ± 10 DEG C of calcining 1-3h, 1300 ± 10 DEG C of calcining 1-2h are finally warming up to.
It is preferred that, step 4) in crush after material particular diameter be 2-3mm, material particular diameter is 0.025-0.038mm after ball milling.
Due to using above-mentioned technical scheme, the beneficial effects of the invention are as follows：The present invention by mixing, heating, precalcining,
The steps such as broken, ball milling, sintering are made, and are cooperated using rational recipe ingredient and processing step, effectively increase each group
The lifting collocation of performance between point, with good thermoplasticity and heat endurance, processability is good, the obtained smooth light of product appearance
Sliding, mechanical strength and translucency are obviously improved, and whiteness is up to 82%, and yield rate effectively increases household china up to more than 95%
Integrated quality.
The daily bone china of the present invention coordinates kaolin and diatomite, sepiolite fibre, sodium alginate, starch using bone ash powder
Deng raw material, first by diatomite, sepiolite fibre, sodium alginate three's hybrid reaction, with diatomite as porous carrier, coordinate sea
Afrodite fiber improves catalytic intensification activity, and the catalytic mixing effect between each component is effectively improved in later stage mechanical milling process,
The difficulty that component surface is activated in mechanical milling process is reduced, coordinates the sodium alginate of addition, dispersant to promote rheological characteristic, enters one
Step improves component grinding efficiency.In addition, crop starch is while certain cementability is provided, amylose therein has one
Fixed like fibrous property, is favorably improved the fit structure intensity between raw material, and amylopectin has larger spatial configuration, tool
There is good moisture sorption effect, for adjusting viscosity thixotropic effect, it is ensured that good flow leveling, promote component hybrid reaction.
Compared to all raw material dinectly bruning sintering during traditional porcelain making, the present invention is using the segmentation precalcining of bone ash powder
Processing, then be sintered with other raw materials, the firing uniformity of bone ash powder is not only ensure that, while sintering temperature can be reduced effectively
And sintering time, comprehensive precalcining and last sintering operation reduce 5- compared to sintering operation cost in traditional handicraft
10%, energy consumption is effectively reduced, and the production cycle is shorter, obtained properties of product are moderately good, after testing, and performance is as follows：
