Non-cracking soft-polishing glazed tile with wavellite effect on surface and preparation method thereof

Abstract

The invention discloses a non-cracking soft-polishing glazed tile with a wavellite effect on a surface and a preparation method thereof. The non-cracking soft-polishing glazed tile comprises a frit, acover glaze, wavellite crystal particles and wavellite crystal particle pulp. On the basis of no significant change for an existing glazed tile production technology, the key points are the optimization of the formula composition of the frit, the formula composition of the cover glaze, the formula compositions of the wavellite crystal particles and wavellite crystal particle pulp and the particlesize of the wavellite crystal particles, regulation and optimization of glazing and pulping technologies, optimization of soft-polishing abrasive bricks and a soft-polishing technology and the like,so that the spherical and columnar wavellite crystal particles on the surface of the prepared glazed tile product are of strong difference with those of lusterless cover glaze in glossiness, shiny starlight like wavellite, which looks like a starry sky in fairy tales and a dream, is emitted under the irradiation of lamplight, and the glazed tile has unique decoration and artistry; through the result of the fitness test of an A.H.Harcourt glaze body, the product is judged that unconditional safety is provided in days without cracking at room temperature, and the disadvantage that an existing glazed tile is cracked after long-term use is solved.

Description

Technical field: [0001] The invention relates to the technical field of preparation of glazed tiles, in particular to a non-cracking soft-polished glazed tile with silver star effect on the surface and a preparation method thereof. Background technique: [0002] Silver star stone is water-containing aluminum phosphate, which is generally spherical or columnar, and the aggregate of crystals is radial, with vitreous or grease luster, and translucent. Silver star stone is generally attached to the rock surface or distributed in the cracks of the rock. After the star stones are polished, these translucent spherical or columnar silver star stones have a strong contrast in luster with their rocky substrates. Under the light, they are like a fairy tale silver sea starry sky, sparkling, dreamlike, and unique. The decorative effect of silver star has been sought after by the upstarts and has become an indispensable ornament in some high-end decorations. However, the natural content o...
