The invention relates to a solid-type filter stick formed by granular assembling and a preparation method of the solid-type filter stick. The filter stick is prepared by the assembling forming of solid granules and an adhesion agent, wherein the solid granules are one or more of natural plant granules, natural mineral granules and artificial adsorption granules. The adhesive agent is one or more of ethylene-vinyl acetate copolymer, polyethylene hot melt adhesive, epoxy resin, polyester, polyether, polyurethane, dextrin, polyvinyl alcohol, polycaprolactone, gelatin and Arabic gum. The mass ratio of the solid granules and the adhesive agent is 0.5-200:1. The filter stick is prepared by the bonding forming after the solid granules and the adhesive agent are mixed, is loosened, breathable and stable in structure, and can be used as a unitary filter tip or can be combined with other filtering materials to form a multi-component filter tip. The preparation method is simple in process and high in production stability. The filter stick is novel in appearance and structure, stable in structure, excellent in incision performance, wide in material selection range, good in filtering effect and capable of effectively improving the smoking quality of cigarettes.

The invention relates to a solid waste-based baking-free environment-friendly hollow brick and a preparation method thereof, and belongs to the field of solid waste utilization environmental protection and the field of hollow bricks. Red mud, mineral powder, industrial by-product gypsum, fly ash, silica fume, aluminum ash, carbide slag, wastewater and other solid wastes and waste liquids are usedas main raw materials. The hollow brick comprises the raw materials in parts by mass: 35-50% of red mud, 30-45% of mineral powder, 10-20% of industrial by-product gypsum, 5-15% of a reinforcing agent,0.5-3% of a cementing agent and the balance of sewage or wastewater, wherein the reinforcing agent is prepared by mixing 15-23% of silica fume, 10-25% of aluminum ash, 20-30% of fly ash, 15-30% of carbide slag, 5-10% of zeolite powder and 5-15% of asphalt. Large-scale resource utilization of solid waste is achieved, the occupied area of the solid waste is reduced, environmental pollution is reduced, no natural mineral resources are consumed during preparation, multiple solid waste and waste liquid are used as main raw materials of the baking-free hollow brick, and the product has the advantages of high strength, low cost, environmental protection, energy conservation, simple and convenient process and easiness in popularization and application.
