Ceramic coloring process

Abstract

The invention discloses a ceramic coloring process. The ceramic coloring process comprises the following steps: preparing a coloring agent through selection and mixing of a coloring compound and chemical raw materials, ball milling of the obtained mixture in a ball mill, sieving of the ball-milled mixture and mixing the screened mixture with a solvent; and then uniformly spraying the coloring agent onto the surface of a ceramic blank, drying the ceramic blank in a constant-temperature drying box, subjecting the dried ceramic blank to secondary atomizing spraying with the coloring agent, sintering the ceramic blank at normal pressure after drying of the coloring agent, preserving heat for 3 h after the ceramic blank is sintered to 1250 to 1400 DEG C from room temperature, and calcining theceramic blank for 6 to 12 h so as to obtain a finished product. Thus, the ceramic coloring process is low in cost and simple in process; a sprayed ceramic has a smooth glaze and a gorgeous surface color; added zirconia effectively prevents the surface of the ceramic from cracks caused by ageing; and the ceramic coloring process has good application prospects.

Description

technical field [0001] The invention relates to the field of ceramic coloring methods, in particular to a ceramic coloring process. Background technique [0002] The production of ceramics in my country enjoys a high reputation in the world. Since the Han Dynasty, clay containing different elements and various plant ashes with different chemical properties have been used as colorants to decorate ceramic products. With the development of society, inorganic compounds of transition metals also As a commonly used pigment, the surface of the existing ceramic blank is glazed, but the surface of the existing coloring process is thickly sprayed, which wastes raw materials and increases costs. Aging phenomena such as cracks. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a ceramic coloring process. The ceramic coloring process of the present invention has low cost and simple process. After spraying, the ceramic glaze sur...
