NOVELTY - Multi-source solid waste absorbing material comprises 45-55 pts. wt. red mud, 30-40 pts. wt. mineral powder, 20-30 pts. wt. fly ash, 15-20 pts. wt. silicon ash, 8-15 pts. wt. steel slag, 6-12 pts. wt. wave absorbing agent, 8-15 pts. wt. polymer, 5-10 pts. wt. regenerated fiber, 6-10 pts. wt. excitant, 0.5-1.5 pts. wt. water reducing agent and 20-30 pts. wt. water. USE - Multi-source solid waste-absorbing material for use in wave absorbing field (claimed), and is useful in the field of building material, where the building material is used in industrial structure adjustment, city construction and emerging industries, building garbage city sludge and electronic garbage. ADVANTAGE - The multi-source solid waste-absorbing material utilizes red mud, mineral powder, silicon ash, fly ash and steel slag as main raw material, which has high solid waste utilization rate, simple manufacturing technique, low in cost, prepared wave absorbing material has good wave absorbing performance, and reduces the reflectivity of the wave absorption material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing multi-source solid waste-based wave absorbing material, which involves: (a) mixing, stirring and ultrasonically treating wave absorbing agent, polymer, activator, water reducing agent and water to obtain aqueous solution; (b) crushing regenerated fiber to obtain refined fiber powder; (c) mixing red mud, mineral powder, fly ash, silicon ash, steel slag and refined fiber powder to obtain mixed material; and (d) adding the aqueous solution, and stirring and forming to obtain a multi-source solid waste-based wave absorbing material.
