Attapulgite construction waste insulating brick

Abstract

The invention discloses an attapulgite construction waste insulating brick. The key points of the technical scheme are as follows: the attapulgite construction waste insulating brick consists of high-viscosity attapulgite clay powders, attapulgite clay tailings powders, construction waste powders, pyroclastic rock mixtures and montmorillonite tailings powders. The ingredients of the attapulgite construction waste are stirred and pressed to be manufactured to semi-finished attapulgite construction waste insulation bricks with different shapes, the semi-finished attapulgite construction waste insulation bricks are conveyed to a tunnel kiln to be sintered into finished attapulgite construction waste insulation bricks. The attapulgite construction waste insulating brick has the characteristics of good smoothness, high strength, good rigidity, light weight, shock resistance, heat insulation, energy conservation, sound insulation, heat insulation, fire protection, flame retardance, weather resistance, crack resistance, water resistance, and reduction of the load of building construction. The most of ingredients of the attapulgite construction waste adopt various wastes, so that not only can the resource utilization ratio be improved, the wastes are turned into wealth, but also the occupied space is reduced, the environment is protected and purified, the energy resources are saved, the production cost is saved, the economical benefits are improved, and the attapulgite construction waste insulating brick 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 an attapulgite building waste insulation brick. Background technique [0002] In addition to attapulgite, attapulgite clay often contains minerals such as montmorillonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate. [0003] Pyroclastic rocks coexist with attapulgite clay deposits. Pyroclastic rocks are mostly in the upper layer of attapulgite clay deposits. In some attapulgite clay deposits, the thickness of pyroclastic rock layers in the upper layer is as high as tens of meters. During the mining of attapulgite clay, pyroclastic rocks in the upper layer of the attapulgite clay mining area are discarded as waste. According to field investigations, more than 30 tons of pyroclastic rocks are produced for every ton of attapulgite clay mined. Calculated at an annual output of 150,000 tons, the generated pyroclastic rocks are as high as 4.5 million tons, which have...

[0003]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
