Abstract

The invention provides a nickel residue thermal insulation ceramic tile preparation method, which comprises: (1) placing nickel residue and a grinding aid into a ball mill, carrying out ball milling,and screening to obtain nickel residue powder; (2) weighing the nickel residue powder, perlite and kaolin, adding a sintering aid and a foaming agent, adding water, grinding, and granulating to obtainpowder; and (3) injecting the granulated powder into a mold, carrying out press molding, drying, and calcining to obtain the nickel residue thermal insulation ceramic tile. According to the preparation method of the nickel residue thermal insulation ceramic tile, the nickel residue can be utilized on a large scale, the problems of nickel residue accumulation and environmental pollution are solved, and environmental protection benefits and economic benefits are achieved; and the prepared ceramic tile has light thermal insulation function, can be applied to external wall thermal insulation of high-rise buildings, reduces the dead weight of the high-rise buildings, and can optimize the structural design of buildings and improve the economy of the buildings.

Description

technical field [0001] The invention relates to a preparation method of thermal insulation ceramic bricks, in particular to a preparation method of nickel slag thermal insulation ceramic bricks. Background technique [0002] Thermal insulation ceramic bricks refer to ceramic bricks with small bulk density, thermal insulation properties, and hindrance to heat transfer. As a ceramic tile, it can be used not only to prevent heat inflow under high temperature environment in summer, but also to prevent heat outflow under low temperature environment in winter. Statistics show that the heat loss of external walls accounts for about 32.1% to 36.2% of the total energy consumption of buildings. Therefore, it is an essential and important content in buildings to adopt thermal insulation treatment on the external wall structure of buildings to reduce building energy consumption. Can reduce the energy used for heating and cooling, and reduce CO 2 , SO 2 emissions, avoid wasting non-re...
