Abstract

The invention belongs to the technical field of ceramic powder, and relates to effect powder for sinking ink as well as a preparation method and application of the effect powder. The effect powder for the sinking ink comprises the following raw materials in parts by weight: 0-13 parts of nepheline, 30-37 parts of quartz, 17-23 parts of lead oxide and 30-40 parts of vanadium pentoxide. The preparation method of the effect powder for the sinking ink comprises the following steps: step a, weighing raw materials: weighing the raw materials according to a formula, and fully and uniformly mixing the raw materials to form a mixture; step b, calcining: calcining the mixture at a certain calcining temperature for a certain time, and naturally cooling to room temperature to obtain a calcined material; and c, crushing and grinding: crushing the calcined material, and grinding to obtain the effect powder for the sinking ink. The sinking ink prepared from the effect powder obtained by the preparation method overcomes the defects that textures presented on tiles by existing sinking ink are not fine and coherent enough, and yellow-green residues exist after firing.

Description

technical field [0001] The invention relates to the technical field of ceramic powders, in particular to an effect powder for sinking ink and its preparation method and application. Background technique [0002] With the rapid development of ceramic inkjet printing technology, the decorative effect of architectural ceramic tiles is also changing with each passing day. And with the improvement of people's quality of life, consumers' requirements for ceramic tiles are gradually increasing, and only rich colors can no longer meet consumers' requirements for ceramic tiles. In order to make ceramic tiles show new decorative effects, ceramic functional inks and functional glazes have gradually become popular. [0003] Of these, sinking inks are highly sought after for their ability to produce a marbled effect on tiles. At present, most commercially available sagging inks use bismuth vanadate as the effect powder, and use bismuth vanadate to decompose into vanadium pentoxide at h...
