Problems solved by technology
[0003] However, the four-needle zinc oxide whiskers on the surface of this anti-static tile are easy to be rubbed off, and in severe cases, the anti-static function will be lost.
This kind of anti-static tiles cannot meet the requirements of being used in various occasions with frequent personnel activities

Embodiment Construction
[0019] The antistatic ceramic tile of the present invention has a flaky ceramic bottom plate and tetraacicular zinc oxide whiskers; a layer of tetraacicular zinc oxide whiskers within the mesh size of a sieve of 80-150 meshes is sintered on the upper surface of the ceramic bottom plate . The commonly used anti-static tiles with a total thickness of 10 mm have a ceramic bottom plate with a thickness of 8 mm and a four-needle zinc oxide whisker layer with a thickness of 2 mm.
[0020] The production steps to manufacture this anti-static tile are:
[0021] Step 1, cloth, evenly put granular ceramic powder for ceramic tiles at the bottom of the mold cavity of the press as the base material for the green body; sift the four-needle zinc oxide whiskers sieved with an 80-150 mesh sieve and evenly put them into the press The upper surface of the green body bottom material in the mold cavity forms the green body fabric.
[0022] Step 2, pressing the green body, applying a pressure of ...

The invention provides an anti-static tile and a production method thereof, and relates to a building decoration material and a production method thereof. The method includes the steps: firstly, for distribution, uniformly placing granular ceramic powder for the tile into the bottom of a mould cavity of a press to serve as a green body backing material, and uniformly putting tetrapod-like zinc oxide whiskers, sieved by a 80-150 mesh sieve, onto the top of the green body backing material in the mould cavity of the press so as to form a green body face material; secondly, for green body pressing, applying 210-280 MPa of pressure into the mould cavity of the press to press the green body backing material and the green body face material into a closely integrated green body; thirdly, for sintering, feeding the green body into a high-temperature kiln, drying the green body at the temperature of 500-600 DEG C for 10-15 minutes, then presintering at the temperature of 950-1050 DEG C for 10-15 minutes prior to presintering at the temperature of 1150-1250 DEG C for 5-6 minutes, cooling, sintering the green body backing material into a ceramic backing plate, and sintering the green body face material to the tetrapod-like zinc oxide whiskers on the upper surface of the ceramic backing plate so as to obtain the anti-static tile.
Description
technical field [0001] The invention relates to a building decoration material and a manufacturing method thereof, in particular to a ceramic tile and a manufacturing method thereof. Background technique [0002] Tetraacicular zinc oxide whisker (ZnOw) is white loose powder in appearance, and has a three-dimensional tetraacicular three-dimensional structure at the microscopic level, that is, the whisker has a core, and four needle-shaped crystals extend radially from the core, each needle-shaped The bodies are all single crystal microfibers, and the angle between any two needles is 109°. The diameter of the center of the whisker is 0.7-1.4 μm, the diameter of the root of the needle is 0.5-14 μm, and the length of the needle is 3-200 μm. The tetraacicular zinc oxide whisker itself is an N-type semiconductor with a tetrapod-like three-dimensional structure. When it is dispersed in the matrix, the adjacent needle-shaped parts overlap each other to form a conductive path, which...
