Abstract
The invention discloses a kind of preparation method of light porous domestic ceramics, preparation process includes：(1) preparation of slurry：Feldspar, quartz, clay with water are mixed, add in water-reducing agent, after adjusting pH value, is uniformly mixed；(2) it foams：Foaming agent and foam stabilizer is taken to be added in slurry, is stirred, obtains the slurry that foam is evenly distributed；(3) it is molded：By in slurry injection gypsum mold obtained in step (2), after standing 15min~2h, extra slurry is poured out, then by after 0.5~1h of mold standing, taking-up obtains green body；(4) it is dry：Green body is placed in drying equipment and is dried, drying temperature is 60 100 DEG C；(5) it is sintered：Dried dry body is placed under high temperature and is sintered, firing temperature is 1100~1200 DEG C, obtains light porous domestic ceramics.Raw material sources of the present invention are extensive, and preparation process, equipment are simple, can former existing household porcelain production line, and easy to operate, production efficiency is high, pollution-free, under the premise of the guarantee porosity is higher, can effectively ensure the mechanical property of product.
Description
Technical field
The present invention relates to ceramic material fields, and in particular to a kind of preparation method of light porous domestic ceramics.
Background technology
The development and application of the lighting production technology of ceramics can not only reduce the usage amount of ceramic body raw material, and
And it can effectively reduce the consumption of various electric power and fuel in Production of Ceramics.It is dirty that the lighting production of ceramics has become reduction at present
It contaminates, economize the land resource and a kind of energy-saving effective way.Ceramic lighting production, the volume that can not only reduce ceramics are close
It spends, convenient for long-distance transport, can effectively save the energy consumption of transport.At present, light ceramics mostly using porous foam ceramic as
It is main, it is chiefly used in building heat insulation material or is used as scavenging material, rarely the lighting production technology of domestic ceramics.
The research of porous ceramics preparation method is as follows at present：
It is raw material that Wu, which is all just being waited using cheap quartz sand, dry-pressing formed using half, by adjusting skeletal grain grain size grade, addition
Surfactant sodium dodecyl base benzene sulfonic acid sodium salt or high-temperature foaming agent calcium carbonate prepare apparent porosity 35~55%, and average pore size is
8~60 μm, the controllable micrometer level porous ceramic filter material with narrow pore-size distribution (PSD) and some strength.The material
It is burnt at a certain temperature, average pore aperture is directly proportional to average aggregate size, and intensity is depended between particles of aggregates
Connecting neck portion intensity, and rise with the increase of consumption of binder and the raising of firing temperature.(Wu Jiezheng, Yi Shiyang, Ouyang
Development [J] the silicates notification of the controllable emblem meter level porous ceramics of a kind of jade, 1993 (3):4-9.)
The method that Sunderman etc. just invented foam process and prepared porous ceramics early in 1973, the method are with dioxygen
The substance that water etc. easily foams adds in ceramic slurry the foamed ceramic for the stomata for forming uniform diameter.There are two special for the technique
Point：First is that foamed system is introduced in slurry system, and hydrogen peroxide occurs reduction reaction and generates bubble.Second is in forming process
Middle foam can vanish, and green body can occupy the space left by bubble.It is small and to hold one's breath the more of hole that this technique can prepare aperture
Hole ceramic product.(Sundermann E,Viedt J.METHOD OF MANUFACTURING CERAMIC FOAM BODIES:
US,US3745201[P].1973.)
Sepulvede is equal to the solidifying process in situ proposed for 1998 with reference to foaming and organic monomer technique.It will foaming
System is added in ceramic slurry, after allowing it that chemical reaction generation gas occurs, then organic monomer is added in foamed slurry, finally
The feature that can occur to solidify in situ by organic monomer under certain condition prepares the green body of porous ceramics.Pass through the technique system
It is standby go out ceramic body there is higher intensity, can be processed on ceramics go back body and moulding.It can be made after being finally sintered
It is standby go out mechanical strength is higher, article shape is made by oneself, the porosity also higher porous ceramic articles.(Sepulveda P,Binner
J G P.Processing of cellular ceramics by foaming and in situ,polymerisation
of organic monomers[J].Journal of the European Ceramic Society,1999,19(12):
2059-2066.)
In above-mentioned several typical porous ceramics preparation methods, it is raw material that Wu, which is all just being waited using cheap quartz sand, is passed through
Adjustment skeletal grain grain size grade, addition surfactant sodium dodecyl base benzene sulfonic acid sodium salt or high-temperature foaming agent calcium carbonate prepare porous ceramics
Method, the factor for influencing aperture is excessive, in production application be difficult to control, it is difficult to steady production.The hairs such as Sunderman
Bright foam process prepares the obtained porous ceramics of method of porous ceramics, and voidage is less and difficult in injection forming
In demoulding, production process is difficult to control, and the qualification rate of finished product is relatively low.The combination foaming of the inventions such as Sepulvede and organic monomer
The solidifying process in situ of technique, can prepare that mechanical strength is higher, article shape is made by oneself, the porosity also higher porous ceramics system
Product, but the operating process of the production technology is complex.The cost of required raw material is higher, is unfavorable for industrial production popularization.
These methods are mostly to prepare functional ceramic material, are difficult to the large-scale production of ceramic ware for daily use.
