Embodiment Construction

[0025] Below in conjunction with embodiment the present invention will be further described:

[0026] 1. The production method of the attapulgite fly ash insulation board: (1) Add the ingredients of the attapulgite fly ash insulation board into the already running twin-shaft forced mixer and stir, and then transport it to the press after stirring evenly, and press it into different shapes semi-finished attapulgite fly ash insulation board; (2) send the semi-finished product to the drying room for natural drying, and transport it to the tunnel kiln for roasting after the moisture content of the semi-finished product is less than or equal to 15%; (3) the roasting process is divided into three stages: the first The first-stage roasting temperature is controlled at 30-300°C, and the roasting time is controlled at 6 hours; the second-stage roasting temperature is controlled at 300-800°C, and the roasting time is controlled at 10 hours; the third-stage roasting temperature is control...

Abstract

The invention discloses a production method for an attapulgite fly ash insulation board. The key points of the technical scheme provided by the invention are that the production method comprises the following steps of: stirring and pressing an accessory of the attapulgite fly ash insulation board to form semi-finished products of the attapulgite fly ash insulation board with different shapes; andconveying the semi-finished products to a tunnel kiln for sintering to obtain a finished product of the attapulgite fly ash insulation board. The accessory of the attapulgite fly ash insulation boardconsists of high-viscosity attapulgite clay powder, attapulgite clay tailing powder, volcaniclastic rock mixture, fly ash, bentonite tailing powder, diatomite tailing powder and straw powder. The attapulgite fly ash insulation board has the characteristics of favorable flatness, light weight, earthquake resistance, heat insulating, energy saving, sound and heat insulation, fire resistance, flame retardance and reduction of house building load. A large amount of various wastes are adopted in the accessory of the attapulgite fly ash insulation board disclosed by the invention, and thus the improvement on the recycling rate is facilitated and wastes are changed into valuables; and in addition, the occupied land can be reduced, the environment is protected and purified and energy sources are saved. The attapulgite fly ash insulation board is suitable for constructing wall bodies 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 fly ash 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 clay deposits, the th...
