Spontaneous-combustion coal gangue brick and production process thereof
The invention discloses a spontaneous-combustion coal gangue brick. Coal gangue, pulverized fuel ash, shale, clay, water, residual tea leaves, a foaming agent and an exciting agent are used as raw materials, the coal gangue, the clay, the shale and the pulverized fuel ash are ground into particles respectively, the residual tea leaves are steamed after being soaked by hot water, and the exciting agent is dissolved; the above processed raw materials are mixed, the mixture is sequentially added with water dissolved with the foaming agent and the exciting agent, residual tea leaf soaking water and remained water to form a mixed material, and the mixed material is roasted to form finished bricks. The produced spontaneous-combustion coal gangue brick can be completely combusted spontaneously without stock and aging, the green brick can be molded well, the dead weight of the finished brick is reduced, the porosity is increased, and the spontaneous-combustion coal gangue brick has moisture-proof and mosquitoes and flies dispelling effects and has a wide application prospect.
