Description
Technical field
The present invention relates to a kind of ceramic exterior wall bricks, ceramic exterior wall brick and its preparation side more particularly to a kind of blasting treatment
Method；Belong to building ceramics field.
Background technique
As our people's living standard is continuously improved, requirement of the majority of consumers to building decoration materials is also increasingly
It is high.Especially in exterior walls of buildings field, the decoration that common silica brick metope or cement wall surface have been unable to meet consumer is aesthetic
Demand.Under the overall situation that architectural ceramic industry is grown rapidly, consumer is increasingly keen to pseudo-classic wall face.Since Antique Imitation Tiles have
Mottled decorative pattern, the trace being seemingly etched give people a kind of aesthetic feeling of time warping, are especially suitable for the building of some pseudo-classic styles
Object decoration of exterior wall, so consumer demand amount is very big, but visible Antique Imitation Tiles are the biggest problems are that effect modelled after an antique in the market
Fruit is not true to nature, and raw material uses lithotome, and price is more expensive.
Chinese invention patent application CN109081677A provides a kind of using high contents of calcium and magnesium skarn type iron tailings as the imitative of raw material
Ancient adobe body is realized while reducing production cost, product quality and performances are effectively ensured and saves high-quality ceramic raw material resource
And environmental protection, there is certain antique effect, but have the disadvantage that the thermal stability of product is bad.Reason is to directly adopt
High contents of calcium and magnesium skarn type iron tailings is as raw material, after magnetic separation, gravity treatment are handled, however it remains iron-bearing mineral and density compared with
Low mineral cause impurity in brick more, and defect is inevitable.
Chinese invention patent application CN109081670A provides a kind of Antique Imitation Tiles prepared using shale, by following raw material systems
It is standby to form: shale, gangue, stalk, sludge, bunt gypsum, white cement etc..Good antique effect is reached, and has been using useless
Object by the way of, significantly reduce energy consumption and Costco Wholesale, but due to inserting too many impurity, generate brick more
Internal flaw, affect the mechanical properties.
Chinese invention patent application CN108892466A provides a kind of iron tailings slag Antique Imitation Tiles and preparation method thereof, adopts
Antique Imitation Tiles are prepared with iron tailings slag, there is good frost resistance, and brick body color is cinerous, color is true to nature, and preparation is simple
It is easy, it is at low cost.But due to being non-burning brick, the problem of it is small that there are density, and building requirements are not achieved in intensity.
Summary of the invention
In order to overcome the deficiencies of the prior art, it is outer using the ceramics modelled after an antique of blasting treatment that the purpose of the present invention is to provide a kind of
Antique effect true to nature is presented in wall brick, gained ceramic exterior wall brick, and mechanical property meets exterior wall tile national standard.
Another object of the present invention is to provide a kind of simple and easy, process stabilizings, the pottery modelled after an antique that can produce in enormous quantities
The preparation method of porcelain exterior wall tile.
First by bottom blank and coral colorant or bottom blank and cobalt blue, zirconium silicate, manganese red, base are black is uniformly mixed as face
Expect basestocks.It is first that metal-imitation glaze powder cloth is good using secondary material distributing, then by fabric basestocks and bottom blank successively cloth in imitative metal
The top of powdered frit is turned using back-hand craft by after brick compression moulding through roll-over table.Dry kiln is sent into obtained adobe
It is dry, it can assign adobe certain dry tenacity, and blasting craft is facilitated to improve yields.Sand-blasting machine blasting treatment is used again,
Since the sand of high speed ejection is to the percussion of workpiece surface, precoat part powder, which is battered down, to fall off, and part powder is impacted
Hole out shows the effect that ancient brick is etched peeling.The surface of brick body, adobe large area quilt are sprayed on the color water debugged again
Then processed brick is burnt by the covering of color water by certain calcining system.Silver color can be presented in metal-imitation glaze powder after firing, and has
Obvious gloss.The hole of precoat, the silvering of metal-imitation glaze powder, color water color are like nature itself, and very true to nature imitate is formed
Ancient effect.The breakdown strength and the modulus of rupture of the ceramic exterior wall brick are much higher than ceramic exterior wall brick national standard, can mention for consumer
Not only there is antique effect true to nature, and the ceramic exterior wall brick of excellent mechanical for a kind of, can be widely used in all kinds of buildings
On beyond the region of objective existence wall.
