Formula and production process of hollow brick taking coal gangue as raw material
The invention discloses a hollow brick formula taking coal gangue as a raw material and a production process. The hollow brick formula comprises the following components: coal gangue, fly ash, straw powder, shale, steel slag, an adhesive, an emulsifier, graphene and water. Modified graphene is introduced into the formula, chitosan modified graphene oxide with positive charges and talcum powder of a layered structure are subjected to electrostatic self-assembly through electrostatic interaction to form a micro-nano hybrid structure, and the micro-nano hybrid structure is dispersed into a green brick, so that the green brick is uniformly shrunk in the roasting process, and deformation of the green brick after firing is reduced; the integrity of the holes can be kept, the heat preservation performance of the hollow brick is improved, and the mechanical property of the hollow brick is improved through the evenly-dispersed modified graphene nanostructure.
本发明公开了一种以煤矸石为原料的空心砖配方及生产工艺，该空心砖配方包括如下组分：煤矸石、粉煤灰、秸秆粉、页岩、钢渣、粘接剂、乳化剂、石墨烯、水。通过在配方中引入改性石墨烯，带正电荷的壳聚糖改性氧化石墨烯通过静电作用与层状结构的滑石粉发生静电自组装形成为微纳米杂化结构，并分散到砖坯中，使得砖坯在焙烧过程中收缩均匀，从而降低砖坯烧制后的变形，能保持孔洞的完整性，提高空心砖的保温性能，并且分散均匀的改性石墨烯的纳米结构提升了空心砖的力学性能。
