Embodiment 1

[0013] Embodiment 1: raw material formula mud 5-25 CaCO 3 30-50 MgCO 3 0-20 high-alumina sand 10-40, after ball milling, spray drying to powder, dry pressing and firing.

Embodiment 2

[0014] Embodiment 2: raw material formula mud 5-25 CaF 2 30-50 MgO0-10 High alumina sand 10-40, after ball milling, spray drying to powder, dry pressing and firing.

Embodiment 3

[0015] Embodiment 3: the powder material made in embodiment 1 or embodiment 2 and the existing polishing brick production powder are mixed in the ratio of 40:60 or 50:50 or 60:40 and then dry-pressed, dried and fired Can.

[0016] In above-mentioned embodiment, owing to have selected CaCO for use in the raw material 3 , CaF 2 , CaO and CO are produced during firing 2 , F 2 etc., where CO 2 , F 2 Gas escapes to generate pores, and CaO plays a role in cooling and promoting sintering, so as to obtain porous sintered functional ceramic bricks with communicating channels.

Abstract

The invention discloses a production method of a porous sintered functional ceramic tile, which comprises the steps that: proportioning according to material ratio of the existing ceramic tile, ball milling, spray drying, pressing forming or squeezing forming, drying-high temperature sintering, and edging treatment. The invention is characterized in that the raw material uses no or less potassium and sodium, but uses material with large burning loss and being easy decomposition and the material takes 10 to 50 percent of the total raw material in the formula; the material, after sintering in high-temperature, forms a porous ceramic body with a communicating passage; the chemical composition of the raw material formula after the sintering process is ( according to weight proportion): 30 to 70 portions of SiO2, 10 to 30 proportions of A12O3, 15 to 40 portions of CaO and 0 to 20 portions of MgO; the material with large burning loss and being easy decomposition adopts one or a plurality of the materials such as CaCO3, CaF2, MgCO3, carbon powder, waste residue of polishing brick, etc. The product produced in the method of the invention has a vitreous body, high rigidity and low cost and has the performances of water seepage, water retention, humidity regulation, anti-skid and sound-proof.

Description

technical field [0001] The invention relates to a functional ceramic brick, in particular to a functional ceramic brick with the functions of humidity control, water seepage, sound insulation and filtration. Background technique [0002] As we all know, the current ceramic production formula will minimize the use of raw materials with large ignition loss and easy to decompose to avoid the generation of pinholes and pores; and with the continuous improvement of people's living standards, indoor wall decoration is not only for aesthetics. There are also certain requirements on functions, such as the ability to adjust humidity, prevent slippage, permeate water, absorb odors, etc., but general ceramic wall and floor tiles cannot provide the above functions. The Chinese patent application number is 01125053, the application date is July 31, 2001, the invention name is porous sintered body and its manufacturing method, and the invention patent application publication / announcement ...
