The present invention provides the preparation methods of on-deformable Nixing pottery plate, including prepare blank, blank forming, body drying and fire green body, and the blank for preparing is by 40~60 parts by weight of eastern mud, 60~40 parts by weight of western mud, 4~8 parts by weight of ZnO, Li₂CO₃0.02~0.04 parts by weight mix, and blank is made according to a conventional method.The present invention adds ZnO and Li in Nixing pottery blank₂CO₃The intensity of mullite network structure in green body can be greatly improved, the appearance of crackle can be effectively reduced, improves firing rate.

Description

The preparation method of on-deformable Nixing pottery plate

Technical field

The present invention relates to the manufacture crafts of Nixing pottery, and in particular to the preparation method of on-deformable Nixing pottery plate.

Background technology

Qiezhou Nixing pottery ranks four big name of China with Jiangsu's purple sand ceramics, Yunnan Jian Shui potteries, Sichuan Rongchang County pottery and makes pottery, and enjoys great prestige At home and abroad.It is raw material that Nixing pottery, which is by the distinctive eastern mud in Qinzhou Prefecture and western mud, by weathering, ball milling, press filtration, vacuum pugging, old Blank is made after corruption, is then made through techniques such as molding, drying, firings.Nixing pottery plate is a kind of decoration being suspended on wall Product, since Nixing pottery plate ornament is large-scale ornaments, the more general Nixing pottery utensil of size it is bigger than normal (length >=0.8m, wide >=0.6m, Thickness >=5cm), firing difficulty is higher, easily cracks and deforms, firing rate is only 40~50%.

Invention content

Technical problem to be solved by the invention is to provide a kind of preparation method of on-deformable Nixing pottery plate, this method The firing rate of Nixing pottery plate can be greatly improved.

Technical solution provided by the invention is a kind of preparation method of on-deformable Nixing pottery plate, including prepare blank, Blank forming, body drying and firing green body, the blank for preparing is by 40~60 parts by weight of eastern mud, 60~40 weight of western mud Part, 4~8 parts by weight of ZnO, Li₂CO₃0.02~0.04 parts by weight mix, and blank is made according to a conventional method.

Li is added in Nixing pottery blank₂CO₃, in sintering procedure, CO₃ ²⁺It can promote around mullite lattice Lacking oxygen Al, Si atom cause lattice more loose further away from Lacking oxygen, help ZnO to enter and form solid solution in mullite crystal, Strengthen the intensity of mullite network structure.The entrance of ZnO is simultaneously dispersed in mullite crystal, plays pinning, entanglement dislocation Effect, it is suppressed that the sliding of dislocation limits fracture, improves Nixing pottery blank strength.

Preferably, the parts by weight of each raw material are：60 parts of eastern mud, 40 parts of western mud, 4~8 parts of ZnO, Li₂CO₃0.02~ 0.04 part.

It is further preferred that the parts by weight of each raw material are：60 parts of eastern mud, 40 parts of western mud, 6 parts of ZnO, Li₂CO₃0.03 part.

The firing green body is by dry base substrate kiln-firing, and elder generation will with the heating rate for increasing 80~130 DEG C per hour Temperature rises to 550~650 DEG C, then temperature is raised to 1110~1160 DEG C with the heating rate for increasing 140~180 DEG C per hour, And at such a temperature, it persistently fires 0.5~1 hour, kiln discharge after cooling completes the firing of green body.

Preferably, by dry base substrate kiln-firing, first to increase 80~100 DEG C of heating rate per hour by temperature liter Temperature is raised to 1140 DEG C to 600 DEG C, then with the heating rate for increasing 160~180 DEG C per hour, and at such a temperature, continued It fires 0.5~1 hour, kiln discharge after cooling completes the firing of green body.

Compared with prior art, the present invention adds ZnO and Li in Nixing pottery blank₂CO₃It can greatly improve in green body not come The intensity of stone network structure can effectively reduce the appearance of crackle and deformation, improve firing rate.

Specific implementation mode
