Coal gangue activity exciting agent and preparation method of active coal gangue powder based on coal gangue activity exciting agent
The invention discloses a coal gangue activity exciting agent and a preparation method of active coal gangue powder based on the coal gangue activity exciting agent. The coal gangue activity exciting agent is obtained by mixing and grinding CaCO3, a C/Al compound, zeolite powder, an iron-based auxiliary agent, a calcium-based auxiliary agent, a rare earth auxiliary agent, KMnO4, isobutanol, fatty glyceride and fluorite. Then crushing coal gangue, grinding, mixing with a coal gangue activity exciting agent, stirring, combusting, and grinding the combusted mixed coal gangue to obtain the activated coal gangue powder. According to the invention, the coal gangue is modified by the active activator, the coal gangue can be subjected to structural change by using combustion heat of the coal gangue in the spontaneous combustion process of the coal gangue, and the coal gangue reacts with the coal gangue, so that the activity of the coal gangue is greatly improved, the mixing amount of the coal gangue in cement is increased, and resource utilization of unnatural coal gangue is realized.
本发明公开了一种煤矸石活性激发剂及基于其的活性煤矸石粉的制备方法。本发明所述煤矸石活性激发剂由CaCO3、C/Al复合物、沸石粉、铁基助剂、钙基助剂、稀土类助剂、KMnO4、异丁醇、脂肪酸甘油酯及萤石混合粉磨得到；之后将煤矸石破碎后粉磨与煤矸石活性激发剂混合搅拌并进行燃烧，燃烧后的混合煤矸石进行研磨得到活化煤矸石粉。本发明通过活性激发剂对煤矸石进行改性，在煤矸石自燃过程中能够利用煤矸石燃烧热量使自身发生结构变化，并与煤矸石进行反应，极大提高煤矸石的活性，使得煤矸石在水泥中的掺量得到提高，实现了未自然煤矸石的资源化利用。
