Abstract

The invention discloses a kind of grey Ceramic Tiles, and it includes base-material and colouring matter, and the colouring matter is silicon aluminium alloy powder.The present invention in ceramic body by introducing silicon aluminium alloy powder, the ceramic adobe of grey is formed after sintering, its gray tone can be adjusted by changing sial ratio gradual change in silico-aluminum, the more traditional ceramic special grey colorant of the simple and convenient of hue adjustment silicon aluminium alloy powders used herein, raw material is easy to get, cheap.The invention also discloses the preparation method of the grey Ceramic Tiles, non-charity white ground-coat enamel in its preparation process, ink-jet decoration, is avoided because there is the problem of white line in trimming chamfer process caused by using white ground-coat enamel directly in grey adobe.

Description

A kind of grey Ceramic Tiles and preparation method thereof
Technical field
The present invention relates to architectural pottery field, more particularly to a kind of grey Ceramic Tiles.
Background technology
With the transformation of interior decoration style, there occurs significant change for the overall colour system of Ceramic Tiles.It was seen everywhere in the past Yellow class style, be gradually hacked, in vain, ash concision style substituted, wherein grey colour system Ceramic Tiles product have it is pure and fresh, graceful Decorating feature, be well received by consumers.At present, grey colour system Ceramic Tiles mainly use the special antimony tin ash colorant of ceramics as color development Raw material.The production process of antimony tin ash colorant is：Metallic tin is first made tin ash, then by tin ash and silica flour, lightweight Calcium carbonate, colouring agent etc. through dispensing, mixing, grinding, calcining, profit mill, washing, dry and obtain.In process of production, unavoidably Generation oxynitrides gas and containing sour waste gas, although taking measures to be administered, but still environment can be polluted.Though have Other grey colour system colorants, such as iron cobalt zirconium ash, nickel cobalt zirconium ash, the grey colour system colorant of manganese zirconium ash, but these grey colorant preparation temperatures Below 1100 DEG C, its high temperature colour stability is poor.Therefore, the grey colour system colorant selection of high-temperature stable is limited, certain journey The development of grey colour system Ceramic Tiles is limited on degree.
The content of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art, there is provided a kind of grey Ceramic Tiles, its high temperature are burnt till Good hair color effect is maintained afterwards, while provides the preparation method of the grey Ceramic Tiles, its environmentally friendly non-environmental-pollution.
The technical solution used in the present invention is：A kind of grey Ceramic Tiles, it includes base-material and colouring matter, the colouring matter For silicon aluminium alloy powder.Specifically, the Surface Creation layer of silicon dioxide diaphragm under the high temperature conditions of the silica flour in alloy, is prevented The further oxidation of silica flour, the black core of silica flour is formd, simultaneously because aluminium powder is active stronger, it is easier to carry out with the oxygen in base substrate Reaction so that aluminium parcel is oxidized around the black core of silica flour, the black tone of remaining silica flour is reduced, shows gray tone.
As the further improvement of such scheme, the mass ratio of silicon and aluminium in the colouring matter is (1~10)：10.Tool Body, by changing sial ratio in silico-aluminum, achievable Ceramic Tiles colour generation is adjusted the present invention by light gray to dark-grey gradual change, So as to form light gray to dark-grey ceramic adobe.
As the further improvement of such scheme, the coloring material granularity is 325~1000 mesh.
As the further improvement of such scheme, according to the weight percentage of raw materials the colouring matter account for gross weight 0.3~ 8%.
As the further improvement of such scheme, the chemical composition of the base-material includes according to the weight percentage of raw materials：60 ~70% SiO2, 16~25% Al2O3, 0.5~0.9% Fe2O3, 0.1~0.5% TiO2, 0.5~5% CaO, 0.5~2% MgO, 0.5~3.5% K2O, 1~5% Na2O and 5~10% burning is lost.
A kind of preparation method of grey Ceramic Tiles as described above, it is comprised the technical steps that：
1) dispensing：Base-material and colouring matter are weighed according to the weight percentage of raw materials, and addition accounts for raw material gross weight 0.2~0.6% Additive, obtain compound；
2) ball milling：Compound and water are added into ball milling in ball mill, solid content 60~70%, ball milling fineness is 250 mesh sieves Remaining less than 0.3%, obtain slurry；
3) mist projection granulating：Slurry is prepared into the base powder that moisture content is 5~8% by mist projection granulating；
4) it is old：Base powder is placed in closed bin old 5~10 days；
5) it is molded：Base powder after will be old is once compressing, obtains adobe；
6) dry：Adobe is entered into dry kiln to dry, 110~180 DEG C of drying temperature, 55~75min of drying time；
7) base is thrown：By throwing the dust that base machine is flat to the throwing of dried adobe surface, exhausting sucks residual；
8) glaze decorating：The direct inkjet printing pattern in adobe surface after putting down will be thrown, then glaze is thrown in charity, obtains semi-finished product；
9) burn till：Semi-finished product are placed in into calcining kiln to burn till, firing temperature be 1180~1230 DEG C, firing period be 50~ 70min；
10) post-production：Semi-finished product burn till after through techniques such as edging, polishing, waxings, obtain environment-friendly type grey Ceramic Tiles into Product.
As the further improvement of such scheme, additive described in step 1) is selected from carboxymethyl cellulose, tripolyphosphate At least one of sodium.
The beneficial effects of the invention are as follows：
(1) present invention forms the ceramic adobe of grey, its ash by introducing silicon aluminium alloy powder in ceramic body after sintering Tone can be adjusted by changing sial ratio gradual change in silico-aluminum, and the simple and convenient of hue adjustment sial used herein closes The more traditional ceramic special grey colorant of bronze, raw material is easy to get, cheap.
(2) non-charity white ground-coat enamel in preparation process of the present invention, ink-jet decoration, is avoided because making directly in grey adobe There is the problem of white line in the trimming chamfer process caused by white ground-coat enamel.
