Sintered candy glaze with concave and convex texture and preparation method of porcelain tile

Abstract

The invention discloses a sintered candy glaze with a concave and convex texture and a preparation method of a porcelain tile. A glaze of the sintered candy glaze with the concave and convex texture comprises printing ink and a transparent frit, wherein the mass ratio of the printing ink to the transparent frit is (2.5-3.5):(0.5-1.5); and the transparent frit is regular spherical particles. According to the sintered candy glaze with the concave and convex texture, the concave and convex texture of the burnt brick surface effect is finer; the decoration effect is more abundant; and the preparation method of the porcelain tile has the advantages of being simple in preparation technology, simple in operation, free of polishing treatment, high in stereoscopic impression of the brick surface effect and low in defective rate.

Description

technical field [0001] The invention relates to the technical field of architectural ceramic decoration materials, in particular to a method for preparing candy glaze and porcelain tiles with concave-convex texture after firing. Background technique [0002] In the existing candy glazed tile production technology, there are two main ways to use glaze to obtain the effect of the concave-convex tile surface. One is to distribute the basic glaze after distributing the basic glaze, and then randomly or at fixed points to distribute molten glaze containing vanadium pentoxide. The surface tension of the special glaze is different from that of the basic glaze, so that the concave-convex texture can be obtained after firing; the other is to use some high-temperature frits and spread them on the surface of the green body. After high-temperature sintering, the high-temperature frits are not completely melted and will Form a certain concave-convex texture. For the second method, the c...

Problems solved by technology

[0003] Therefore, it is proposed to mix the frit particles with the printing ink produced by ceramics to form a sprayable slurry, and apply it on the surface of the body by spraying, but currently limited by conditions, this spraying method is still available. There are many disadvantages, for example, the shapes of transparent frits of the same fineness in the existing candy spray glazes are different, and the irregular shape of the transparent frits makes it easy to cause the spray gun to be blocked during the glaze spraying process ; After high-temperature firing, some are soft-polished, and some are not polished, but after high-temperature firing, the transparent frit in the candy glaze is easy to melt and flatten, resulting in the candy after firing. The concave-convex texture of the glazed tiles is not strong and delicate enough, and the touch is not delicate enough, so the final processed candy glazed tiles do not have a strong three-dimensional effect
