Abstract

The invention discloses a kind of environment-friendly black Ceramic Tiles, and it includes base-material and colouring matter, and the colouring matter is black simple substance silica flour.The present invention forms the ceramic adobe of black, adobe will not cause environmental pollution without toxic heavy-metal elements, preparation process by introducing black simple substance silica flour in ceramic body after sintering.The more traditional ceramic special black pigment of black simple substance silica flour used herein, raw material is easy to get, cheap, is advantageous to large-scale industrial production.The invention also discloses the preparation method of the black ceramic brick, 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 black adobe.

Description

A kind of environment-friendly black Ceramic Tiles and preparation method thereof
Technical field
The present invention relates to architectural pottery field, more particularly to a kind of black ceramic brick.
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 black system ceramics brick product have dignity, allusion quotation Refined, noble decorating feature, is well received by consumers.At present, black ceramic brick mainly using the special cobalt-chromium-iron of ceramics, The black pigments such as cobalt-chromium-iron-manganese, cobalt-chromium-iron-nickel are color development raw material, but the price of cobalt is very high always, result in black ceramic Brick cost is higher.In order to reduce the preparation cost of black pigment, Chinese invention patent CN103274761A discloses a kind of Cu- Mn-Fe-Cr is without cobalt black color ceramic pigment and preparation method thereof.Meanwhile also have and use the waste material containing coherent element to be prepared for raw material Black pigment, as Chinese invention patent CN106046857A discloses a kind of side that black ceramic colorant is prepared using cobalt manganese waste material Method and black ceramic colorant and Chinese invention patent CN106046857A disclose one kind and prepare black ceramic using chromium system waste material The method and black ceramic colorant of colorant.But all contain substantial amounts of heavy metal element in the compositing formula of these black pigments, such as Chromium, manganese etc., its production process can form pollution of the heavy metal ion to water and soil to a certain degree.Therefore, ceramics of environment-friendly type at present Black pigment is always one of problem of industry primary study.Chinese invention patent CN102241529A discloses a kind of parcel charcoal The preparation method of black pottery porcelain color, this method use carbon black to be wrapped up for color development source by zirconium silicate presoma carbon black, suppression The black high-temperature oxydation of charcoal processing.But the heat-resisting quantity of the parcel carbon black black pigment is poor, when temperature be higher than 1000 DEG C, its black tone Drastically weaken.Therefore, there is presently no a kind of environment-protecting and non-poisonous black pigment can be applied to high temperature black Ceramic Tiles field.
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 environment-friendly black Ceramic Tiles, it is high Temperature maintains good hair color effect after burning till, while provides the preparation method of the black ceramic brick, and its environmental protection is dirty without environment Dye.
The technical solution used in the present invention is：A kind of environment-friendly black Ceramic Tiles, it includes base-material and colouring matter, described Colouring matter is black simple substance silica flour.
Specifically, the black simple substance silica flour in the present invention can use commercially available black simple substance silica flour or solar photovoltaic silicon plate The remaining silica flour waste material of cutting processing.
As the further improvement of such scheme, the granularity of the colouring matter is 200~2000 mesh.
As the further improvement of such scheme, according to the weight percentage of raw materials the colouring matter account for gross weight 1~ 10%.
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 environment-friendly black 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 black 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.
As the further improvement of such scheme, the marking ink described in step 7) selected by ink jet process is selected from white The colour system such as ink or golden yellow chromatic ink.
The beneficial effects of the invention are as follows：
(1) present invention forms the ceramic adobe of black, brick by introducing black simple substance silica flour in ceramic body after sintering Base will not cause environmental pollution without toxic heavy-metal elements, preparation process.Black simple substance silica flour used herein is more traditional The special black pigment of ceramics, raw material is easy to get, cheap, is advantageous to large-scale industrial production.
(2) non-charity white ground-coat enamel in preparation process of the present invention, ink-jet decoration, is avoided because making directly in black adobe There is the problem of white line in the trimming chamfer process caused by white ground-coat enamel.
