Embodiment 1

[0036] A preparation of ceramic handicrafts, comprising the following steps:

[0037] S1. Green body preparation:

[0038] S11. Select the corresponding raw materials according to the green body formula, mix potassium feldspar, quartz, kaolin, wollastonite, lithium china stone, bentonite, talc, and alumina, and perform wet ball milling to pass through a 350-400 mesh sieve, and the sieve balance 0.2-0.4wt%;

[0039] S12. Then continue to add polymethyl methacrylate, calcium silicate, konjac glucomannan and lanthanum oxide, stir evenly to obtain a green body slurry, and the flow rate of the green body slurry is about 40 seconds;

[0040] S13. Shape the green body slurry to obtain a rough green body. After the appearance of the rough green body is trimmed, it is immersed in a sodium bicarbonate solution with a pH of about 8.0, and the temperature is raised to 60° C. for 25 minutes, and then taken out and air-dried to obtain a green body.

Abstract

The invention discloses a ceramic handicraft, comprising a green body and a glaze layer. The green body is prepared from the following raw materials: 35-40 parts of potassium feldspar, 25-30 parts of quartz, 10-15 parts of kaolin, and 10-15 parts of wollastonite. parts, 8-12 parts of lithium porcelain stone, 8-12 parts of bentonite, 7-10 parts of calcium silicate, 6-8 parts of talc, 5-8 parts of alumina, 3-6 parts of polymethyl methacrylate, konjac grape 3-6 parts of mannan, 1-2 parts of lanthanum oxide; the glaze layer is made from the following raw materials: 25-30 parts of quartz, 10-15 parts of albite, 10-15 parts of potassium feldspar, and 15-20 parts of kaolin , 10-15 parts of diatomaceous earth, 8-12 parts of zirconium silicate, 5-8 parts of magnesium sulfate, 5-8 parts of zinc oxide, 3-5 parts of boron oxide, and 1-4 parts of coloring agent. The invention can reduce the firing temperature by optimizing the raw material component selection and content ratio of the green body and the glaze layer, and meanwhile, the ceramic products have uniform and dense texture, low water absorption rate, smooth and uniform surface of the glaze layer, and beautiful appearance.

Description

technical field [0001] The invention belongs to the technical field of ceramic products, in particular to a ceramic handicraft and a preparation method thereof. Background technique [0002] Ceramics is a general term for pottery and porcelain, and the existence of pottery was discovered as early as about 8000-2000 BC (Neolithic Age). Ceramic materials are mostly oxides, nitrides, borides and carbides. Common ceramic raw materials include clay, alumina, kaolin, etc. Since the main raw materials of ceramics are silicate minerals from nature, they belong to the same "silicate industry" as glass, cement, enamel, refractory and other industrial fields. category. The formed ceramic products generally have high hardness, but poor plasticity. In addition to the use of food utensils, utensils and decorations, ceramic products also play an important role in the development of electronic science. The preparation process of ceramics is mostly made by crushing, mixing, molding and c...
