Embodiment 1

[0071] raw material:

[0072]

[0073]

[0074] Preparation Process:

[0075] 1) Put coal gangue, albite and foaming agent into a ball mill according to the amount used, and perform wet ball milling for 18 hours to obtain a ball-milled slurry with a fineness of 300 mesh; the foaming agent is manganese dioxide.

[0076] 2) Inject the ball-milled slurry into the spray tower for spray drying, and control the outlet temperature at 400°C to obtain powder;

Abstract

The invention belongs to the technical field of foamed ceramic light inner wall board preparation, and particularly relates to a foamed ceramic light inner wall board prepared from coal gangue and graphite tailings and a preparation method. The foamed ceramic light inner wall board is prepared from, by weight, 60-70% of coal gangue, 10-15% of albite, 1-3% of foaming agent and 15-25% of microlite aggregates. The foamed ceramic light inner wall board has the advantages of being good in chemical stability, high in strength, resistant to quick heating and cooling, capable of achieving class-A fire protection, resistant to corrosion, high in adsorption performance, low in specific gravity, good in heat preservation performance, capable of achieving sound insulation, easy to cut and the like. The foamed ceramic light inner wall board is the fireproof thermal insulation material needed in the market; in addition, the foamed ceramic light inner wall board has the advantages that the comprehensive cost is low, installation is convenient, the foamed ceramic light inner wall board can be repeatedly used, the construction speed is twice faster than that in the prior art, energy is saved, consumption is reduced, the wall body is a half or less as thin as a traditional building block, the usable area of a house can be increased, the service life of the foamed ceramic light inner wall board is as long as the building, and the foamed ceramic light inner wall board is an ideal interior and exterior wall material for a fabricated building.

Description

technical field [0001] The invention belongs to the technical field of preparation of foam ceramic light-weight inner partition wall boards, in particular to a foam ceramic light-weight inner partition wall board prepared from coal gangue and graphite tailings and a preparation method thereof. Background technique [0002] With the development of my country's national economy, new wall materials in the construction industry are facing the challenge of replacement. In the "National Economic and Social Development 'Twelfth Five-Year' Plan and 2015 Vision Outline", building energy conservation and waste utilization have been listed important industry for the country. In recent years, my country's residential buildings have entered a period of large-scale construction, and wall materials account for 70% of building materials, and their demand has greatly increased. [0003] Faced with the use of such large-scale wall energy-saving materials, the development of new clean energy a...
