Production method of polished tiles having jade stone texture

Abstract

A production method of polished tiles having a jade stone texture, wherein the polished tiles is prepared from following raw materials: high-whiteness albite powder being 5-10 wt% in the content of sodium, feldspar, clay, talcum being 28-32 wt% in the content of MgO, anorthite being 2.0-4.0 wt% in the content of CaO and bone ash being 45-50 wt% in the content of CaO. The production method includes following steps: powder producing, blank body moulding, high-temperature sintering and polishing. During the blank body moulding, firstly more than more than one stacks of a granular powder material is randomly arranged on a material arranging trolley in the form of a large-granular materials, and then a layer of mixed powder material is arranged at the periphery of the granular powder material. The powder materials are press-compacted by a press roller and then are cracked naturally, wherein the cracks are filled with a super-transparent jade material. Finally the prepared materials are fed into a die cavity for being compression-moulded. Compared with a method in the prior art, the production method is free of addition of a reinforcing agent and a whitening agent (such as zirconium silicate) which are harmful to environment. The polished tile has a super-transparent sense just like jade stone, is fine-and-smooth and has a layered sense, is clear in bottom pattern, and has such an excellent jade-like texture.

Description

technical field [0001] The invention relates to a ceramic tile and a production method thereof. Background technique [0002] The micropowder polished tiles in the existing market are all made of Na2O, K2O, MgO ternary system structure, plus a certain amount of zirconium silicate. The whiteness is generally around 40 degrees, the light transmittance is poor, and the texture is not enough. It does not have the texture of jade stone, and the added enhancers and brighteners (such as zirconium silicate) are harmful to the environment. Contents of the invention [0003] The purpose of the present invention is to provide a kind of jade stone with super light transmittance, fine and layered, clear bottom flower and such a good jade feeling without adding a harmful environment enhancing agent and whitening agent (such as zirconium silicate). The invention discloses a production method of a polished tile with a jade stone texture. [0004] The present invention is achieved in thi...
