Description

A kind of composite environment-friendly architectural pottery and preparation method thereof
Technical field
The present invention relates to a kind of composite environment-friendly architectural pottery and preparation method thereof, belongs to architectural pottery technical field.
Background technology
Now, in China or even the whole world because architectural engineering and household engineering decorative, finishing material noxious material it is exceeded and Radiation and cause endanger health of people report it is more and more, environmental pollution is also serious all the more.Domestic construction engineering and household Engineering decorative, the experts and scholars of finishing, the environmental issue to this field also faces the big problem for being badly in need of solving.It is multi-functional One of ceramic Main way to become the development of architectural pottery field of compound Green environmental-protection building.
Architectural pottery production technology traditional at present is with fire clay, feldspar, quartz as base substrate primary raw material, while adding Plus some chemical industry additives such as zirconium are increasing whiteness, the hardness porosity etc. of architectural pottery.Due to using chemical industry additive, category In non-renewable resource, in use can the harmful substance such as release formaldehyde, benzene, TVOC, natural environment and human body are made Into pollution and injury.
In recent years, China's building material market occurs in that various nontoxic, harmless environmental-friendly construction materials.It can only itself nothing The pernicious gases such as poison, harmless formaldehyde, ammonia, the benzene that can not be distributed to other materials are purged and environmental protection.
In consideration of it, be necessary to provide a kind of new composite environment-friendly architectural pottery, to solve the deficiencies in the prior art.
The content of the invention
An object of the present invention, is to provide a kind of composite environment-friendly architectural pottery.The composite environment-friendly building of the present invention Ceramics, with following function:1. purify air;2. odor function is eliminated:Remove the life such as smoke, peculiar smell of pet, toilet different Taste;3. there is high performance antibiotic property, and with anti-corrosion function;4. antistatic performance;5. adjusting air humidity, with uniqueness " aquatic respiration " function;6. fire protection flame retarding;7. abrasion resistance is high, and hardness is strong;8. it is radiationless.
The technical scheme that the present invention solves above-mentioned technical problem is as follows:A kind of composite environment-friendly architectural pottery, by weighing as follows The raw material of amount percentage is made:Oyster shell whiting 30-70%, kaolin 17-40%, ball clay 9-20% and potassium feldspar 4-10%.
The present invention adopts oyster shell whiting, kaolin and ball clay for main raw material(s), and three, can through 900-1000 DEG C of sintering To increase the whiteness and viscosity of architectural pottery product.Additionally, adding the potassium feldspar of 4-10%, the strong of architectural pottery is improved Degree, abrasion resistance.Simultaneously the present invention adopts natural oyster shell whiting for raw material, through high-temperature sterilization grinding, without any nuisance The pernicious gases such as matter, not emitting formaldehyde, ammonia, benzene, TVOC, and with adsorbing, decompose the function of these pernicious gases.

The second object of the present invention, the preparation method of the present invention is scientific and reasonable, it is easy to implement, high yield rate is significantly reduced Production cost, wide market is adapted to large-scale production.
The technical scheme that the present invention solves above-mentioned technical problem is as follows:A kind of preparation side of composite environment-friendly architectural pottery Method, comprises the steps:
(1) making of oyster shell whiting
1.1 clean in shell, and boiling water is boiled, drying, obtain the shell dried;
1.2 sieve the shell of step 1.1 gained drying, ball milling, obtain oyster shell whiting;
1.3 by step 1.2 gained oyster shell whiting, dries, the oyster shell whiting after being dried;
(2) making of composite environment-friendly architectural pottery
2.1 raw materials for taking following percetage by weight:By step 1.3 gained oyster shell whiting 30-70%, kaolin 17-40%, ball Clay 9-20%, potassium feldspar 4-10%, after being well mixed, ball milling obtains the ceramic raw material after ball milling;
2.2, by the ceramic raw material after step 2.1 gained ball milling, sieve, mist projection granulating, and room temperature is dried, and drying after forming connects Glazing after biscuiting, then glaze firing, obtain final product the composite environment-friendly architectural pottery.
The operation of preparation method of the present invention is simple, and low cost while improve the purity and productivity ratio of product, and was produced Harm is not constituted to natural environment in journey, seashore solid pollution is reduced, the waste material in production process is favorably improved acid ground In pH value, so as to maintain natural equilibrium.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Further, the time that boiling water described in step 1.1 is boiled is 10-20min.
It is using above-mentioned further beneficial effect:Shell can be carried out disinfection.
Further, the time of ball milling described in step 1.2 is 50-70min, and the mesh number sieved is 300-425 mesh.
It is using above-mentioned further beneficial effect:Crushed can shell so as to and other raw material fully melt Close.
Further, the temperature dried described in step 1.3 is 100-200 DEG C, and the time is 10-30min.
It is using above-mentioned further beneficial effect:The water content of gained oyster shell whiting can be reduced.
Further, the percetage by weight of raw material described in step 2.1 is:Step 1.3 gained oyster shell whiting 60%, kaolin 23%, ball clay 11%, potassium feldspar 6%, the time of the ball milling is 30-40min.
Further, the time of ball milling described in step 2.1 is 30-40min.
It is using above-mentioned further beneficial effect:Raw material can be sufficiently mixed.
Further, in the oyster shell whiting calcium weight content >=95%.
Further, the mesh number sieved described in step 2.2 is 300-425 mesh;The particle diameter of the mist projection granulating is 80-100 mesh, Moisture content is 6-7%;The room temperature is 18-25 DEG C, and the time of the drying is 10-15min;It is described be shaped to it is dry-pressing formed, One kind in injection forming, extrusion molding, hot die-casting molding;The temperature of the drying after forming is 100-150 DEG C, and the time is 30-50min;The temperature of the biscuiting is 900-1000 DEG C, and the time is 2h;The temperature of the glaze firing is 1050-1200 DEG C.
It is using above-mentioned further beneficial effect:The present invention uses the primary raw material that oyster shell whiting is architectural pottery, not only The whiteness of architectural pottery product, viscosity and hardness can be increased, and strengthen architectural pottery product absorption pernicious gas Function.The pernicious gas that traditional architecture ceramics are produced due to additive and the shortcoming for radiating not only are solved, while changing The problem of traditional architecture ceramics strength
Wherein, biscuiting described in step 2.2, refers to the sintering process of the ceramic green of non-glazing.The Main Function of biscuiting It is that the intensity for improving base substrate is beneficial to the process such as decoration, reduces loss.
The invention has the beneficial effects as follows:
(1) present invention replaces quartz in raw material with oyster shell whiting, is combined with kaolin and ball clay using oyster shell whiting Characteristic, not only can increase whiteness, viscosity and the hardness of architectural pottery product, because the content increase of calcium in product makes its hole Porosity increases, and strengthens the function that architectural pottery product adsorbs pernicious gas.On the other hand, the addition of a large amount of calcium enhances building The intensity of ceramic product, this is because calcium reduces dry contraction, prevents product from ftractureing.The present invention solves traditional architecture ceramics The pernicious gas produced due to additive and the shortcoming of radiation, while changing the problem of traditional architecture ceramics strength.
