Low-temperature fast-fired environmentally-friendly pottery clay plate prepared from iron ore tailings and preparation method thereof

Abstract

The invention relates to a low-temperature fast-fired environmentally-friendly pottery clay plate prepared from iron ore tailings and a preparation method thereof. Iron ore tailings obtained by iron ore enterprise production is used as a main solvent raw material and is adopted by a formula of the low-temperature fast-fired environmentally-friendly pottery clay plate. The low-temperature fast-fired environmentally-friendly pottery clay plate comprises a superfine plastic material, a fine lean material, fine iron ore tailings, a coarse lean material, a plasticizer and water. The formula of the low-temperature fast-fired environmentally-friendly pottery clay plate comprises illite, kaolin, chinastone, pyrophyllite, iron ore tailings, the coarse lean material, the plasticizer and water. The preparation method comprises the following steps of uniformly mixing 15 to 35% by mass of the superfine plastic material, 10 to 45% by mass of the fine lean material and the coarse lean material, 20 to 50% by mass of iron ore tailings and 0 to 5% of by mass of the plasticizer, adding 10 to 28% by mass of water into the mixture, carrying out extrusion molding by a screw-type extruder, drying, and carrying out sintering in a roller kiln having the length of 280 meters at a temperature of 1000 to 1100 DEG C, wherein a sintering period is in a range of 1 to 1.5 hours. The mixed raw materials adopted by the preparation method have good extrusion performances and good drying and sintering performances. The low-temperature fast-fired environmentally-friendly pottery clay plate sintered by the preparation method has high strength and small contractility, cracks and deforms difficultly, can be sintered fast and has high environmental protection benefits and economic benefits.

Description

technical field [0001] The invention relates to a building decoration material, in particular to a method for preparing a low-temperature fast-fired clay board by using iron ore tailings. Background technique [0002] Clay panels, also known as ceramic panels, are made of natural clay as the main raw material, using various industrialized advanced equipment, and through multiple processes of fine processing, it is a panel with considerable strength, hardness and relatively precise geometric size and shape requirements. It is the application of traditional materials in modern architecture, and it is an ingenious and perfect combination of traditional materials, modern industrial technology and modern architecture. Clay panels adopt various curtain wall dry-hanging technologies to make the entire curtain wall system safe, firm and durable. The unique hollow structure and natural clay of the clay board have the characteristics of green environmental protection, no radiation, m...

Problems solved by technology

For the existing extrusion molding process, it is required that the mud has better plasticity and higher moisture content than ordinary dry molding. Higher moisture content and higher plasticity will make the drying cycle longer and the drying pass rate is low, etc.

The pottery plate formula used by most domestic manufacturers adopts the original brick and tile formula or the formula of daily-use ceramics. The raw materials used are all natural clay, which is a waste of natural resources, and most of the manufacturers now have a firing cycle of 7 to 8 hours. Left and right, a great waste of energy such as electricity and gas
