NOVELTY - Preparing wave-absorbing coating material, comprises (1) mixing absorbent, adhesive agent and auxiliary agent to obtain spraying component one, dissolving catalyst in organic solvent to obtain spraying component two; (2) orderly spraying spraying component one and spraying component two on the substrate alternately; and (3) placing obtained product at room temperature for curing and molding. USE - The method is useful for preparing wave-absorbing coating material. ADVANTAGE - The method realizes fast porous of the wave-absorbing coating material by spraying agent preparation-spraying treatment-coating curing molding three-step method, greatly shortens the maintenance time of the wave-absorbing coating, reduces the manpower and material resources, and reduces the maintenance costs.
