Attapulgite and pyroclastic rock heat-insulating refractory aggregate

Abstract

The invention discloses attapulgite and pyroclastic rock heat-insulating refractory aggregate. According to the technical scheme, the attapulgite and pyroclastic rock heat-insulating refractory aggregate is characterized by comprising high-viscosity attapulgite clay powder, attapulgite clay tailing, pyroclastic rock mixture, expanded perlite, diatomite tailing, gangue and bentonite tailing. The materials of the attapulgite and pyroclastic rock heat-insulating refractory aggregate are mixed well, crushed, soaked, pressed, roasted, crushed and screened and are packed to obtain the finished attapulgite and pyroclastic rock heat-insulating refractory aggregate. The attapulgite and pyroclastic rock heat-insulating refractory aggregate is high in particle strength, sound-proof, heat-insulating, fireproof and flame-retardant. Various wastes are used to make the attapulgite and pyroclastic rock heat-insulating refractory aggregate, so that resource utilization rate can be increased, waste is turned into wealth, occupied land can be reduced, environment can be protected and purified, energy resources can be economized, production cost is lowered, and economic benefit is increased. The attapulgite and pyroclastic rock heat-insulating refractory aggregate is applicable to heat-insulating refractory concrete works.

Description

technical field [0001] The invention relates to a refractory material, in particular to an attapulgite pyroclastic rock heat-insulating refractory aggregate sand. Background technique [0002] Refractory materials are mainly made of natural ores such as bauxite, silica, magnesite, and dolomite after processing. [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] Pyroclastic rocks are symbiotic with attapulgite cla...

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
