Abstract

The invention discloses a high-strength ceramic glaze for splicing ceramic blanks and a preparation method of the high-strength ceramic glaze. The glaze is composed of the raw materials in parts by weight: 20-25 parts of fly ash, 3-8 parts of kaolin, 20-35 parts of feldspar, 2-5 parts of bauxite, 3-5 parts of calcite, 1-3 parts of aluminum oxide, 0.5-1.5 parts of cerium dioxide, 1-2 parts of cerium trifluoride, 5-8 parts of borosilicate modified phenolic resin, 0.5-1 part of zinc oxide and 10-20 parts of ceramic waste material. The glaze is prepared by grinding the raw materials in batches, calcining, uniformly mixing and pulping. According to the invention, reasonable formula setting is adopted; the ceramic waste material and the borosilicate modified phenolic resin are introduced, so that the glaze has good ductility and high strength, is good in adaptability with the ceramic brick blanks and excellent in post-processing performance, the purpose that the specification of the ceramicblanks is consistent with that of a glaze surface is achieved, and the technical defect that the processing difficulty is high due to the fact that the specification of the ceramic blanks is too largeis overcome.

Description

Technical field [0001] The invention belongs to the field of glazes, and specifically relates to a high-strength ceramic glaze used for splicing ceramic blanks and a preparation method thereof. Background technique [0002] In recent years, in major exhibitions and technical seminars related to ceramics, ceramic slabs have become the most eye-catching products. The large-area decorative effects are favored by consumers and are widely used in subways, hotels, etc. field. [0003] However, ceramic slabs also have defects. Due to their large area, they are prone to shrinkage and deformation during the firing and preparation process; this greatly limits the production and sales market of ceramic slabs. In addition, due to the large area and thin thickness of large ceramic plates, how to improve their strength is also an important factor in expanding the market. Summary of the invention [0004] The present invention forms a large ceramic plate by splicing small-sized ceramic bodies, a...
