Problems solved by technology

Secondly, ethylene glycol and printing oil are added in the preparation of the full glaze (that is, raw materials: ball stone: ethylene glycol: printing oil = 1: 1.8-2: 0.25: 0.3), which not only increases the production cost, but also easily leads to glaze defects. production
Patent CN102603364A discloses a raw material formula and preparation method of super wear-resistant and high hardness full-polished glaze. The full-polished glaze pulping process is completed in two steps: first, the ingredients are ball-milled to prepare the glaze slurry, and second, the prepared thickener is proportionally Mix with the glaze slurry for 40-60 minutes, and the production efficiency is low; (2) The proportion of alumina added in the composition of the full glaze is 10 parts, that is, 10%. Since corundum alumina is a relatively high-priced raw material, its proportion will increase significantly Increasing the cost will also increase the ball milling time and reduce production efficiency

Abstract

The invention relates to a full polish ceramic product and a preparation method thereof. The full polish ceramic product comprises a ceramic green body and a full polish layer outside the ceramic green body, wherein the full polish layer mainly comprises powder which comprises following components by weight percent: 42-62% of albite, 2-7% of potash feldspar, 0-4% of dolomite, 4-8% of calcite, 0-2% of barium carbonate, 6-8% of aluminum oxide, 3-5% of fired talc, 2-4.6% of zinc oxide, 3-9% of quartz powder, 0.5-2.5% of soochow kaolin, 1-6% of calcined kaolin, 5-10% of aedelforsite, 0.1-3.0% of spodumene, and 0.1-2.8% of borocalcite. The full polish slurry is prepared by burdening and ball milling once. As the full polish slurry contains less wearproof materials like aluminum oxide, the ball milling time is short, and the production efficiency is higher; due to the addition of little amount of spodumene and borocalcite, the abrasion performance and hardness of the fired full polish ceramic product can be improved.

Description

technical field [0001] The invention belongs to the technical field of ceramic production, and in particular relates to a fully glazed ceramic product and a preparation method thereof. Background technique [0002] At present, inkjet printing technology is widely used in the development of new ceramic decoration products. The advantage of ceramic inkjet printing is that the design of color varieties is more flexible, the amount of color glaze is more economical, and the pattern texture is more realistic. However, due to the extremely high amount of glaze Less, resulting in easy wear of the color glaze pattern, which seriously affects the decorative effect. In order to further retain the decorative effect of ceramic inkjet printing and make up for its lack of use, a layer of wear-resistant and transparent full-polished glaze is applied on the color glaze pattern of ceramic products. Polishing the glaze after firing can solve this problem. However, the wear resistance of ordi...
