Method for making micro powder ceramic polished brick have vivid stone effect

Abstract

The method of making polished fine powder ceramic tile possess vivid stone material effect is the secondary material distributing process with the facing material. The present invention features the facing material powder for secondary material distributing, and the fine powder is prepared with the materials including clay, quartzite, feldspar powder, calcspar powder, talcum powder and silicate melt of expansion coefficient 200-250, and consists of CaO 10-25 wt%, MgO 0.5-5 wt%, Al2O3 3-16 wt%, SiO2 57-63 wt%, B2O3 1-2 wt%, ZnO 2-8 wt% and K2O+Na2O 1-8 wt%. The polished fine powder ceramic tile of the present invention has vivid stone effect and may be used in replace decorating natural stone material.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a method for manufacturing ceramic polished tiles. Background technique [0002] At present, there is a kind of ceramic polished tile with imitation stone effect on the market, such as micropowder brick, micropowder filled glazed brick and so on. Most of these polished tiles use the secondary distribution process, that is, during the process of pressing the adobe, the material is distributed to the mold of the brick press twice. First, a layer of powder is laid in the mold as the base material, and then fine powder The powder is used as the fabric, and the color of the brick surface can be adjusted by changing the color of the fabric layer. The prior art has not yet found a suitable fabric formula, so that the fabric layer of the finished ceramic polished tile can simulate the translucent jade texture that high-grade stone has. Another method of imitating stone effe...

Problems solved by technology

Since the added transparent frit is generally as big as a finger, that is, the mesh size is generally between 40 and 8 mesh, it is difficult to achieve a natural and random effect when mixing with the powder, and it is difficult to achieve a natural and random effect during the stamping process. Easy to delaminate, severe wear to the mold, easy to crack and produce severe deformation during drying and firing
