The invention relates to a coal gangue imitation stone and a preparation method thereof. Coal gangue of three particle size grades is selected as a base material, the effect of the coal gangue imitation stone prepared from the coal gangue of the three particle size grades as the base material is closer to that of natural stone than that of a product prepared from coal gangue of the same particle size, and the prepared coal gangue imitation stone is good in visual effect, high in simulation degree and higher in product quality. A reinforcing agent for enhancing the compressive strength and breaking strength of the coal gangue imitation stone is added, so the problem that the compressive strength and breaking strength of the produced coal gangue imitation stone are both at a low level due tothe fact that the particle size of a coal gangue base material is uneven can be effectively solved, the compressive strength and breaking strength of the produced coal gangue imitation stone are greatly improved, and thus the produced coal gangue imitation stone meets the national standard. Coal gangue is used for replacing clay to become a new manufacturing building material, waste is turned into wealth, the production cost of the coal gangue imitation stone is effectively reduced, energy is saved, and the environment is protected.
本发明一种煤矸石仿石材及其制备方法，选用三种粒度等级的煤矸石作基材，三种粒度等级的煤矸石作基材制出的煤矸石仿石材比选用同一粒度的煤矸石制出的产品更接近天然石材的效果，制备得到的煤矸石仿石材的视觉效果好，仿真度高，产品品质更高；加入了用以增强煤矸石仿石材的抗压强度及抗折强度的增强剂，可以有效解决煤矸石基材的粒度不均会导致的产出的煤矸石仿石材的抗压强度和抗折强度都处在较低水准的问题，使得产出的煤矸石仿石材的抗压强度及抗折强度得到极大提升，从而使生产出的煤矸石仿石材符合国标标准；用煤矸石代替粘土成为新的制造建筑材料，变废为宝，不仅有效降低煤矸石仿石材的生产成本，还节能环保。
