7. In the step 1), crushing the coal gangue into particles with the particle size of 2mm by a crusher, and arranging a dust collector with the air volume of 1200 above the middle of a lower-layer conveying belt to suck away floating dust on the surfaces of the coal gangue particles; and (3) grinding the coal gangue in the step 1) to 300-400 meshes by using a vertical mill.

Some processes (drying, dipping, film coating, cooling, edge cutting, packaging and warehousing) in the step 4) are conventional processes, so detailed description is omitted.
Because the coal gangue powder has high surface energy, the binding degree of acid oxides such as silicon and aluminum and the like and asphalt is good through the modification of the disproportionated resin, and compared with calcite powder, talcum powder and the like which are used as coiled material frameworks, fillers and the like, the coal gangue powder has the effect of obviously improving the tensile strength. In other words, the filling amount can be increased. The overall weight of the coiled material made of the coal gangue with the average specific gravity of 2.1-2.5 is 15-20% lighter than that of the coiled material produced by calcite, thereby reducing the transportation weight and greatly enlarging the sales transportation radius. The coal gangue is solid waste discharged in the coal mining and coal washing processes, saves resources and forms economic benefits of comprehensive utilization of the solid waste. Because the coal gangue has the effect of grinding, the grindability of raw materials can be improved, the yield of the raw materials can be increased, and the power consumption of raw material grinding can be reduced. The coal gangue is generally gray black, a large amount of calcite with whiteness close to 90 is used in the production of the waterproof roll, and the product produced after the materials are mixed is also black, so the appearance and the service performance of the product are not influenced.
Examples
Because the coal gangue has the grinding-aiding effect, the grindability of raw materials can be improved, the yield of the raw materials can be increased, and the power consumption of raw material grinding can be reduced. If the raw material mill is a 2650 type vertical mill, the power of a main motor is 900kw, the yield of raw materials before milling of 400-mesh calcite raw materials and blending of coal gangue is 100t/h, the yield after milling by using coal gangue as the raw materials is improved to 120t/h compared with that of calcite milled by the same equipment, 1.5 degrees of electricity can be saved for one ton of raw materials, the operation time of the vertical mill is 20 hours a day, and 90000 degrees of electricity can be saved for one month by calculating 25 days a month.
The coal gangue is generally gray black, a large amount of calcite with whiteness close to 90 is used in the production of the waterproof roll, and the product is also black after being prepared, so the appearance and the service performance of the product are not influenced.
The overall weight of the coiled material prepared by the coal gangue with the average specific gravity of 2.1-2.5 is 15-20% lighter than that of the coiled material produced by calcite, so that the transportation weight is reduced, and the sales and transportation radius is greatly enlarged.
Based on the purposes of reasonably utilizing resources, saving energy and reducing consumption, the ecological environment can be improved as long as the method is proper and measures are taken, the principle of social sustainable development is met, and the method has wide market application prospect and practical significance.
The production process of the products such as the SBS coiled material, the self-adhesive coiled material, the asphalt tile and the like by utilizing the coal gangue accords with the pre-processing key points of the production process of the products, the production formula of the products such as the SBS coiled material, the self-adhesive coiled material, the asphalt tile and the like by utilizing the coal gangue, the grafted resin is the asphalt interface modifier to endow the asphalt with polarity and bondability, the interface bonding force of the asphalt and inorganic fillers such as glass fiber, coal gangue powder and the like can be improved, and the tensile strength, the impact strength and the bending strength of the modified products are improved.
