Embodiment 1

[0025] Add 70% of polished brick waste, 8% of clay and 22% of recycled waste powder into appropriate sodium hydroxymethyl cellulose, sodium tripolyphosphate, and water into a ball mill for ball milling to make a brick with a moisture content of not higher than 36%. After the slurry is spray-dried, the sprayed dry powder is pressed into a size of 600mm×600mm×15mm with a pressure of 27M Pa. After drying, the moisture content of the green body is less than 0.1%, and the tunnel kiln is fired at 1185°C. After firing, the density of the product is less than 1300kg / m3, and the breaking strength is more than 800N. After firing, the product is edged and packaged to be a finished product. It is an excellent lightweight building material.

Embodiment 2

[0027] Process 50% of polished brick waste, 5% of clay and 45% of recycled waste in the same way as above, press the sprayed dry powder with a pressure of 45Mpa, and spray transparent glaze on the surface for decoration. After drying, it is fired in a shuttle kiln at 1230°C become. The appearance of the product is good, and it also has the properties of a lightweight material.

Embodiment 3

[0029] Add 0.5% manganese red material to 38% polished brick waste, 34% mud and 28% recycled waste powder, add 19% water, and use a vacuum mud mill to make mud. The old mud is passed through the extruder to 3M Pa pressure extrusion molding 300 × 300mm mud board, after drying, it is fired in roller kiln at 1265°C. After firing, the product is reddish, with good decorative effect and physical properties.

Abstract

The invention discloses a light-weight ceramic brick, which is a light-weight ceramic brick fired at high temperature and has a honeycomb-like internal structure of closed pores. The invention also discloses a preparation method of the above-mentioned lightweight ceramic tiles, which is formed by dry pressing after wet ball milling, sieving, iron removal, spraying drying tower and powder spraying on the vitrified brick polishing waste produced in large quantities in the ceramic industry at present. Method forming, or kneading using wet extrusion molding, and then firing products in continuous or batch kilns. Manufacture a kind of lighter quality ceramic tiles, aiming at the insufficient use of waste materials in the past, more effectively utilize industrial waste residues in large quantities, and because of its light structure, it can be used in the decoration of high-rise building walls, It has good properties such as light weight, high strength, heat preservation, and sound absorption, and it can significantly reduce the weight of the wall structure. At the same time, it also has the characteristics of easy transportation, easy construction, and fast speed. It has great advantages in saving energy and reducing the weight of buildings. The outstanding advantage is that it is an environment-friendly building ceramic decoration material.

Description

technical field [0001] The invention relates to a production method of light-weight ceramic tiles, in particular to a light-weight ceramic tile which is produced by using vitrified brick polishing waste and has good performances such as heat absorption and sound insulation, and also relates to its specific production process. Background technique [0002] With the continuous progress of society, people's requirements for environmental protection are getting higher and higher. At present, the production of a large number of vitrified tile polishing waste in the ceramic industry has a great impact on the environment. The degree of treatment and utilization of polished brick waste slag is relatively low, and most of them are landfilled, resulting in a large amount of waste slag occupying cultivated land, polluting water and air. How to effectively deal with waste has become a common concern of ceramic manufacturers and ceramic workers. Patent CN1377859A discloses a method of us...
