Description

A kind of large-sized ultra-thin stoneware-quality tiles and preparation method thereof
Technical field:
The present invention relates to technical field of construction and decoration materials, particularly a kind of large-sized ultra-thin stoneware-quality tiles and preparation method thereof.
Background technology:
Generally along with the increase of product specification, the thickness of Ceramic Tiles also constantly increases.The raw material that the unit area Ceramic Tiles is consumed is also many more, has increased the weight of the carrying of building.Ultra-thin brick economizes in raw materials, and cuts down the consumption of energy, and has become the ceramic industry developing tendency in future.Standard GB/T 4100.4-1999 dry-pressing Ceramic Tiles the 4th part Shi matter brick water absorption rate need be controlled between 6%<E≤10%.Ultra-thin stoneware-quality tiles has guaranteed the intensity and the pliability of product owing to added relatively large fiber-like reinforcing agent, make product specification meet or exceed 900 * 1800mm, and moulding thickness only is 3~6mm.This large-sized ultra-thin stoneware-quality tiles high resilience and pliability preferably resolve the fragility problem of Imitation Rock Porcelain Tiles.Simultaneously it also has the unexistent characteristics such as big, thin, light of other common size ceramic product.After glaze is decorated, have imitative stone material or wallpaper decoration effect, can be used as the facing plate and replace wallpaper, hard board, stone material etc.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of big specification Shi matter brick of ultra-thin environmental protection is provided.This ultra-thin brick adhibit quality is good, the intensity height, and good straightness degree, high resilience and pliability, the abrasion resistance height, antifouling property is good, fire-proof high-temperature resistant, long service life and "dead" pollution.This product can alleviate the load-bearing of building, has fabulous ornamental again.
The present invention adopts following technical scheme to realize above-mentioned purpose:
A kind of large-sized ultra-thin stoneware-quality tiles and preparation method thereof adopts dry-pressing formed technology to introduce 5~30% fiber enhancers in base substrate, the main chemical compound of base substrate: SiO 255~68%, Al 2O 314~28%, Fe 2O 30.5~1.8%, TiO 20.2~1.5%, CaO 1~12%, MgO 0.3~1%, K 2O+Na 2O 2~5%.
Fiber enhancer of the present invention can be mineral fibers such as acicular wollastonite, basalt mineral fiber etc., also can be synthesize ceramic fiber such as alumina silicate fibre, alumina fibre, kyanite fiber and other manmade inorganic fibre etc.Can adopt the one or more combination in mineral fibers or the synthesize ceramic fiber in the prescription.3~6 microns of average fibre diameters, draw ratio 10~60, and have certain hydrophily, dispersiveness will be got well in mud.
A kind of large-sized ultra-thin stoneware-quality tiles, described preparation method's processing step comprises: selected raw material, and---------------------old---combined filament slurry in the pulp storage tank is shaped batching---drying---glazing printing ornament---roller kilns once-firing---pick---edging---classification---packing warehouse-in in spray-on process powder process in deironing in grinding slurrying to stack old, homogenizing.Described preparation method's processing step press forming stage is adopted dry method compression moulding, and molding thickness is 3~6mm, and product specification can meet or exceed 900 * 1800mm.Also can first biscuiting after the drying kiln drying is dry again the glazing printing ornament carry out glaze firing, i.e. twice firing.Require in the ball-milling technology blank ball milling to 10000-hole sieve is tailed over 0.8%~1.0%; Roller kilns once-firing temperature is 1140 ℃~1160 ℃.Twice firing biscuiting temperature is 1130 ℃~1150 ℃, 1080 ℃~1100 ℃ of temperature of glaze firing.Fibre stuff needs independentization slurry to carry out mechanical mixture with common slurry again.
Be that the base substrate of 1050mm * 2060mm * (3~6) mm has enough intensity simultaneously, reduce damaged in order to guarantee to enter specification before the calcining kiln.Needing to add the base substrate reinforcing agent cooperates the clay of more high adhesion stress to increase the intensity of green compact.The base substrate reinforcing agent can be the one or more combination of polyvinyl alcohol, sodium carboxymethylcellulose or oxidized starch.
The present invention adopts the beneficial effect that can reach after the technique scheme to be:
Introduce intensity and toughness that relatively large ceramic fibre improves finished bricks.Have the unexistent characteristics such as big, thin, light of other common size ceramic product.Mode by serigraphy or roller printing after the glazing obtains required pattern, clear-cut texture, and pattern is true to nature naturally, can be used as the substitute of wallpaper, hard board, stone material etc.
