The raw materials for making ceramic flooring tile are (by weight portion) 1000 portions of feldspar, 600-1500 portions of quartz, 1600-2500 portions of clay and 8-32 portions of diluting agent.Said invention adopts solid slip casting method to form, and after forming its drying temp. is 50-70 deg.C., and its product possesses high hardness and bending strength and good spalling resistance.

Description

A kind of Ceramic Tiles and preparation method thereof

The invention belongs to a kind of Ceramic Tiles and preparation method thereof.

The existing Ceramic Tiles that is used for floor file face is the plane, and its function is to pave the way or decorative ground.

The present invention aims to provide a kind of not only can be used for and paves the way or decorative ground, and human body is had health-care effect and long-lived Ceramic Tiles and preparation method thereof.

The technical scheme that realizes above-mentioned purpose is: this Ceramic Tiles comprises plate body (1), it is characterized in that, is provided with the prominent mound (2) of some cobble shapes on the plate body upper surface.

The further scheme of Ceramic Tiles of the present invention is: the chemical constituent of this adobe following (weight)

SiO ₂?65～72％????Al ₂O ₃?20～26％Fe ₂O ₃?0.5～1.2％?K ₂O?1.5～3.2％

Embodiment 1

The process of this routine Ceramic Tiles is:

1, blank batching: the composition of raw materials of blank and weight proportion are:

9 parts of 500 parts of water glass of 500 parts of quartz of 1000 parts of feldspars of black mud

1000 parts in water;

The clay that this routine used black mud is a high-ductility, outward appearance is black;

2, ball milling: above-mentioned batching is added ball mill, and being processed into fineness is 1.2～6.0% (250

Mesh sieve) mud, its moisture content is controlled at 28～30%, concentration 66～72Be;

3, mud pit is old: pulp is old to mud pit behind the ball milling, old about 50 hours;

4, moulding: adopt the solid casting method of forming, mud is poured into gypsum mold in the formed body

Interior moulding, the demoulding;

5, drying: the wet base after the demoulding placed carry out drying in the drying shed, because product structure is multiple

Assorted, type is thicker, and the temperature schedule in the drying room is controlled at 60 ± 10 ℃;

6, soak glaze: dried blank is soaked glaze;

6, burn till: the combustion gas shuttle kiln of packing into is fired, and firing period is about 10 hours, firing temperature

1200℃；

7, branch is grade packaged.

The above-mentioned process for preparation that soaks the used glaze of glaze is: because this product firing temperature is higher, so full raw material of raw material in the glaze, batching was gone into 1.5 tons of ball mill ball millings 16 hours, fineness requirement is (325 mesh sieve) below 0.1%, moisture content 33 ± 2%, about concentration 60Be, be diluted to 55Be ± 2Be during glazing, soak glaze, glazing weight 150 to 300 gram/pieces.Embodiment 2 adds 300 parts of kaolin and 100 parts of living talcums again on the basis of embodiment 1 batching.Adding kaolin can improve the intensity of brick, adds living talcum and can reduce firing temperature.Embodiment 3～embodiment 6

Produce base substrate with the foregoing description 3,4, at demould time, firing temperature, glacing flatness, geometry regularity and other comprehensive product index aspect of burning the back product all slightly are better than other embodiment, and embodiment 4 is a most preferred embodiment.

Explanation to several primary raw materials:

Feldspar of the foregoing description and quartz are to derive from porcelain sand, and porcelain sand is a kind of feldspathic ceramic raw material that each ceramics factory generally adopts in the southern porcelain district, mainly by feldspar, the quartzy composition, with fashion small amount of Fe are arranged ₂O ₃, magnesite, nepheline, mica etc., this example is that the deal that required feldspar and quartzy deal are converted into porcelain sand is fed intake in actual production.

Black mud, white clay all belong to the clay category, are a kind of clay minerals that generally adopts in the southern porcelain district, and black mud is the clay that outward appearance is black, and white clay is the clay that outward appearance is white in color.Two kinds of clay mineral impurity contents are fewer, and degree of fire resistance is higher, and pure whiter after the burning, mullite crystal is grown the more, and its quality better.Owing to have certain difference on the microstructure of mineral, the plasticity of shades of colour (as also having red soil) clay is distinguishing, wherein with black mud and white clay for well, and the plasticity of black mud is stronger than white clay.

Give birth to talcum: this example is introduced living talcum can reduce firing temperature, quickens the generation of mullite crystal, can improve the mechanical strength and the heat stability of goods simultaneously.
