Problems solved by technology

However, because the glaze contains more particles with smaller particle sizes, it is easy to agglomerate during the preparation of the glaze, the dispersion effect is poor, or it takes a long time to mix and disperse, which greatly wastes production time and increases production costs. Production cost; and the glazes in the prior art have limited improvement of ceramic surface strength and wear resistance, and ceramic products are difficult to meet more and more extensive use requirements

preparation example Construction

[0020] The invention provides a kind of preparation method of glaze, comprising the following steps:

[0021] (1) Weigh the dry raw materials in the glaze formula according to the formula, add them into the mixing tank of the planetary mixer and stir and mix to obtain the dry raw material mixture;

[0022] (2) transfer the dry raw material mixture into a ball mill, add water accounting for 5-10% of the total water weight to wet the dry raw material mixture, ball mill, and pass through a 800-1200 mesh sieve after ball milling;

[0023] (3) Transfer the sieved dry raw material mixture into the mixing tank of the planetary mixer, add the remaining amount of water, vacuumize to -0.05~-0.1MPa, stir and mix in vacuum for 50~60min, and finally adjust the water content to 53~58%, obtain described glaze.

[0024] In the present invention, the dry materials in the glaze formula are mixed in advance, so that the dry materials are mixed more fully and evenly, which avoids the easy agglom...

Embodiment 1

[0054] A method for processing ceramic products, comprising the steps of:

[0055] S1: blank processing and blank forming processing,

[0056] Including crushing and sieving blocky solid materials to obtain granular raw materials; followed by iron removal, mud dehydration, aging, mud refining, and granulation to obtain a billet with particle gradation and good fluidity;

[0057] Form the blank into the shape of a ceramic product, then use mixed abrasives to spray the surface of the blank at high speed, and then dry it to obtain a green body;

[0058] The mixed abrasive includes a mixture of aluminum oxide, silicon oxide, diamond powder and glass powder, each raw material component is ball milled and passed through a 1100 mesh sieve, and the mass ratio of aluminum oxide, silicon oxide, diamond powder and glass powder is 1 :0.3:1.4:0.6;

[0059] The conditions of the high-speed spraying include: using nitrogen as the carrier gas, the output of the mixed abrasive is 65g / min, th...

Embodiment 2

[0068] The processing method of ceramic products as provided in Example 1, the difference is that in step S2, the glaze includes the following raw materials in parts by weight: 28 parts of potassium feldspar, 35 parts of quartz, 10 parts of talcum powder, and 5 parts of corundum , 5 parts of glass powder, 3 parts of alumina powder, 4 parts of sodium silicate, 1 part of diamond powder, 10 parts of cobalt green pigment, 70 parts of water;

[0069] Others remain unchanged, and the ceramic product is obtained by processing according to the processing method of Example 1.

Abstract

The invention belongs to the technical field of ceramic and in particular relates to a glaze material and a preparation method thereof. The preparation method comprises the following steps: (1) weighing drying materials in a formula of the glaze material according to formula amounts; adding the drying materials into a mixing tank of a planetary mixer to perform striring and mixing until a dry rawmaterial mixture is obtained; (2) transporting the dry raw material mixture into a ball-milling machine; adding water which accounts for 5 to 10 percent of the total amount of the water to wet the dryraw material mixture; carrying out ball milling; sieving through a sieve with the size of 800 to 1200 meshes after carrying out the ball milling; (3) transporting the sieved dry raw material mixtureinto the mixing tank of the planetary mixer; adding the balance of the water and vacuumizing until the pressure is -0.05 to -0.1 MPa; stirring and mixing for 50 to 60 min in vacuum; finally, adjustingthe moisture content to be 53 to 58 percent, so as to obtain the glaze material. By adopting the preparation method of the glaze material, provided by the invention, the dispersion and mixing effectof the glaze material is remarkably improved, and the prepared glaze material has relatively high surface strength and wear-resisting performance.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a glaze and a preparation method thereof. Background technique [0002] In the traditional concept, ceramics are artificial industrial products based on inorganic non-metallic minerals such as clay. It includes various products made of clay or a mixture containing clay after mixing, forming, and calcination. It ranges from the roughest earthenware to the finest fine pottery and porcelain. Its main raw material is silicate products obtained from nature, such as clay, quartz and so on. With the development of science and technology, many new ceramic varieties have emerged in recent years. They no longer use or rarely use traditional ceramic materials such as clay, feldspar, and quartz, but use other special raw materials, and even expand to non-silicic acid. The scope of salt, non-oxide, and many new processes have emerged to process it, so the meaning of ceramics ha...
