Abstract

The invention discloses a microcrystalline foamed wall block produced by use of tailings and a manufacturing method of the microcrystalline foamed wall block. According to the microcrystalline foamed wall block, a decorative surface layer is sintered on a tailing microcrystalline foamed base body manufactured by use of a tailing composite material at a high temperature. The manufacturing method comprises the following steps: (1) preheating, namely increasing the temperature to the range of 800-950 DEG C and preserving heat for 10-40 minutes; (2) integrated sintering, namely increasing the temperature to the range of 1000-1350 DEG C and preserving heat for 30-120 minutes; (3) annealing cooling, namely cooling to below 280 DEG C and then taking out of a kiln; (4) naturally cooling to below 100 DEG C and then performing mold stripping, thereby obtaining a microcrystalline foamed wall block board; naturally placing the microcrystalline foamed wall block board for more than 60 hours to eliminate stress, and then grinding or polishing, cutting and drying to obtain the microcrystalline foamed wall block. The microcrystalline foamed wall block has a plurality of functions of high strength, fire resistance, heat preservation and thermal insulation, moisture and water proofing, decoration, light weight, weathering resistance, environmental protection and the like.

Description

technical field

[0001] The invention relates to the technical field of building engineering materials, in particular to a microcrystalline foamed wall block produced by using tailing sand and a manufacturing method thereof. Background technique

[0002] With the gradual scarcity of energy in the world, my country has formulated the basic principle of "conserving energy and realizing sustainable development". Therefore, building energy conservation has also become a focus of the development of China's construction industry. At present, the main means of building energy conservation is external wall insulation technology, which can effectively solve the problem of energy loss caused by the indoor and outdoor temperature difference between winter and summer in my country. It represents the development direction of my country's energy-saving insulation technology.

[0003] The current external wall thermal insulation system is composed of polymer mortar, glass fiber mesh cloth, ...
