Problems solved by technology

[0003] At present, the preparation of coal gangue imitation stone with coal gangue has the following disadvantages: (1) coal gangue of the same particle size is used as the base material to prepare coal gangue imitation stone, and the prepared coal gangue imitation stone has poor visual effect, low degree of simulation, and low product quality. (2) When coal gangue with various particle sizes is used as the base material to prepare coal gangue imitation stone, the compressive strength and flexural strength of the produced coal gangue imitation stone will be lower due to the uneven particle size of the coal gangue base material. At a lower level, the products produced do not meet the national standard

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of building material preparation, in particular to a coal gangue imitation stone and a preparation method thereof. Background technique [0002] Coal gangue is a solid waste discharged from the coal mining process and coal washing process. Including the excavation gangue in the process of tunnel excavation, the gangue extracted from the roof, the bottom plate and the interlayer during the excavation process, and the washing gangue picked out during the coal washing process. Its main components are Al2O3, SiO2, and also contain varying amounts of Fe2O3, CaO, MgO, Na2O, K2O, P2O5, SO3 and trace rare elements gallium, vanadium, titanium, cobalt, etc. Coal gangue is not used, occupying a large area of ​​land. The escape or leaching of sulfides in coal gangue will pollute the atmosphere, farmland and water bodies. Gangue mountains will also spontaneously combust and cause fires, or collapse in the rainy season...
