Attapulgite volcaniclastic rock heat insulation firebrick

Abstract

The invention discloses an attapulgite volcaniclastic rock heat insulation firebrick. The technical scheme is characterized in that the attapulgite volcaniclastic rock heat insulation firebrick is composed of highly viscous attapulgite clay powders, attapulgite clay tailings, volcaniclastic rock mixtures, expanded perlite, diatom earth tailings, coal gangues and bentonite tailings. Materials of the attapulgite volcaniclastic rock heat insulation firebrick are subjected to stirring, compressing, drying, calcination and cooling and packaged to form a finished product of the attapulgite volcaniclastic rock heat insulation firebrick. The attapulgite volcaniclastic rock heat insulation firebrick has the advantages that the strength is high, the brick is noise and heat insulating, fireproofing and flame retardant, a large number of various wastes are utilized in the materials of the attapulgite volcaniclastic rock heat insulation firebrick, the resource utilization rate is increased, waste materials are changed into valuable things, the occupied land is reduced, the environment is protected and purified, the energy is saved, the production cost is lowered, the economic benefits are improved, and the attapulgite volcaniclastic rock heat insulation firebrick is suitable for heat insulation and fireproofing constructions.

Description

technical field [0001] The invention relates to a refractory material, in particular to an attapulgite pyroclastic rock heat-insulating refractory brick. Background technique [0002] There are many kinds of raw materials for refractory bricks, and the composition is mainly divided into six categories: soil, stone, sand, ore, powder and other materials. [0003] 80% of my country's mineral resources are associated mines, a large amount of valuable resources are stored in tailings, and tailings stockpiles require a large amount of land. Many tailings ponds have been used beyond the time limit or overloaded, or even operated in violation of regulations, which has caused great safety hazards in the tailings ponds and posed a serious threat to the property and life safety of people in surrounding areas. [0004] In addition to attapulgite, attapulgite clay often contains minerals such as bentonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate. [0005] Pyroclast...

AI Technical Summary

Problems solved by technology

[0005]Pyroclastic rocks coexist with attapulgite clay deposits, and pyroclastic rocks are mostly in the upper layer of attapulgite clay deposits, and some attapulgite clay deposits The thickness of the pyroclastic rock layer in the upper layer of the mining area is as high as tens of meters. During the mining process of the attapulgite clay, the pyroclastic rock in the upper layer of the attapulgite clay mining area is discarded as waste. According to field investigations, every ton of attapulgite clay mining Rodstone clay produces more than 30 tons of pyroclastic rocks. Calculated at an annual output of 150,000 tons, the pyroclastic rocks produced are as high as 4.5 million tons. They have not been utilized for many years, and the entire mining area is re-accumulated everywhere. Pyroclastic rock mixture, causing serious waste of resources and economic losses
