Problems solved by technology

However, due to the single color of the ceramic itself, the appearance of the ceramic material is poor. The existing gradient color ceramics are glazed on the pure color ceramics by spraying. This method is not environmentally friendly, easy to fade, and the inferior colored glaze is in long-term contact with the human body. unhealthy

preparation example Construction

[0030] refer to figure 1 , a preparation method of gradient color ceramic material comprising:

[0031] Step S1: mixing the azeotropic mixture solvent, dispersant and ceramic powder to obtain a first mixture.

[0032] Specifically, the azeotropic mixture solvent includes at least two of water, ethanol, methyl ethyl ketone, trichloroethylene, toluene, xylene, and ethyl acetate, and the dispersant includes ethoxylates, triethanolamine, fatty amine salts, and fish oil. at least one.

[0033] Step S2: adding a plasticizer and a binder into the first mixture and mixing to obtain a second mixture.

[0034] Specifically, step S2 includes:

[0035] adding a plasticizer and a binder to the first mixture and mixing to obtain the second mixture;

[0036] Or, the plasticizer is covered on the surface of the first mixture, so that the plasticizer forms a plasticizer film on the surface of the first mixture, and the binder is added to the plasticizer film to The binder and the plastici...

Embodiment 1

[0058] Step S1: Add 100 grams of zirconia ceramic powder and 1 gram of ethoxylate into 50 grams of an azeotropic mixture solvent composed of water and ethanol and disperse evenly by ball milling to obtain a first mixture.

[0059] Step S2: Add 1 gram of plasticizer and 2 grams of binder to the first mixture in sequence, specifically, add the plasticizer from the surface of the first mixture so that the plasticizer is on the surface of the first mixture forming a plasticizer film, adding a binder into the plasticizer film, and mixing evenly after the binder is dissolved in the plasticizer to obtain a second mixture.

[0060] Step S3: The second mixture is equally divided into 5 parts, and the colored oxide CoO.Al2O3 is used as a coloring material according to 0.10wt%, 0.15wt%, 0.20wt%, 0.25wt%, 0.30wt% of the zirconia ceramic powder Add to each part of the second mixture in turn, carry out graded ball milling to disperse evenly, ensure that the average particle size D50 of the ...

Abstract

The invention discloses a preparation method of a gradient ceramic material, which comprises the steps of mixing an azeotropic mixture solvent, a dispersing agent and ceramic powder to obtain a firstmixture, adding a plasticizer and a binder into the first mixture, mixing to obtain a second mixture, respectively adding pigments with continuously changed mass gradients into the second mixture, respectively obtaining mixed slurry with continuously changing pigment concentration gradients, respectively carrying out tape casting on the mixed slurry with continuously changing pigment concentrationgradients to obtain tape casting sheets with continuously changing pigment concentration gradients, sequentially superposing the tape casting sheets according to the pigment content from high to low,then carrying out isostatic pressing to obtain a green body, and sequentially carrying out rubber removal treatment and sintering treatment on the green body to obtain the gradient ceramic material.The preparation method is simple, the ceramic material is uniform in color transition, rich and attractive in color, environmentally friendly and safe, and the appearance of the ceramic material is improved on the basis that the ceramic material has excellent corrosion resistance and abrasion resistance.

Description

technical field [0001] The invention belongs to the technical field of gradient color ceramics, and in particular relates to a preparation method of gradient color ceramic materials. Background technique [0002] Ceramics have excellent corrosion resistance and wear resistance, and are widely used in the fields of industry, commerce and daily necessities. However, due to the single color of the ceramic itself, the appearance of the ceramic material is poor. The existing gradient color ceramics are glazed on the pure color ceramics by spraying. This method is not environmentally friendly, easy to fade, and the inferior colored glaze is in long-term contact with the human body. Bad for health. [0003] In view of this, a preparation method of gradient color ceramic material is provided. Contents of the invention [0004] The purpose of this application is to address the above-mentioned defects in the prior art, and to provide a preparation method of gradient color ceramic ...
