Production method of attapulgite building rubbish ceramsite heat insulation board

Abstract

The invention discloses a production method of an attapulgite building rubbish ceramsite heat insulation board, which has the key points of the technical scheme that the ingredients of the attapulgite building rubbish ceramsite heat insulation board are stirred and pressed into attapulgite building rubbish ceramsite heat insulation board semi-finished products with different shapes; and the obtained semi-finished products are conveyed into a tunnel kiln to be sintered into the attapulgite building rubbish ceramsite heat insulation board finished products. The attapulgite building rubbish ceramsite heat insulation board comprises the ingredients including highly viscous attapulgite clay powder, attapulgite clay tailing powder, circular attapulgite building rubbish ceramsite, pyroclastic rock mixture, bentonite tailing powder and straw powder. The attapulgite building rubbish ceramsite heat insulation board has the characteristics of being good in flatness and high in strength, having functions of heat preservation, energy conservation, sound insulation and heat insulation, preventing fire, being flame retardant and reducing the house building load. The heat insulation board adopts a great deal of wastes in the ingredients, thus not only being beneficial to improving the resource utilization rate and changing wastes into valuable, but also reducing the occupied land, protecting and purifying the environment and saving energy; and therefore, the attapulgite building rubbish ceramsite heat insulation board is suitable for the wall construction of various buildings.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a production method of an attapulgite construction waste ceramsite insulation board. Background technique [0002] 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. [0003] In addition to attapulgite, attapulgite clay often contains minerals such as montmorillonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate. [0004] Pyroclastic rocks coexist with attapulgite clay deposits. Pyroclastic rocks are mostly in the upper layer of attapulgite clay deposits. In some attapulgite ...

[0004]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 attapulgite clay, the pyroclastic rock in the upper layer of the attapulgite clay mining area is discarded as wast
