NOVELTY - A wave-absorbing slurry comprises 60-90 pts. wt. adhesive, 60-100 pts. wt. absorbent, 100 pts. wt. solvent, 0.1-1 pt. wt. dispersant, 0.1-0.5 pt. wt. anti-settling agent, and 0.1-1 pt. wt. toughening agent. USE - Wave-absorbing slurry for honeycomb absorbing material (claimed). ADVANTAGE - The wave-absorbing slurry improves impedance matching effect of the honeycomb material and air under the condition that the overall thickness of the honeycomb is constant, and avoids the problem that the mechanical properties of the absorbing material is reduced by the multilayer honeycomb bonding method, and achieves a broadband and efficient absorbing effect under a thinner thickness. the finished white honeycomb is directly used for impregnation, the process is simple and economical and has high operability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of the wave-absorbing slurry, which involves pouring the adhesive into the solvent, fully stirring with a disperser, adding the absorbent, dispersant, anti-settling agent, and toughening agent to the above-mentioned uniformly stirred solution, and stirring with the disperser; (2) honeycomb absorbing material, which prepared by impregnating the absorbing slurry on the substrate. The honeycomb absorbing material is a multilayer structure. The number of structural layers is at least 2. According to impedance matching, design different structure layers, the height of each layer and the weight of each layer to be impregnated; and (3) preparation of the honeycomb absorbing material, which involves dividing the white honeycomb into multiple regions from top to bottom according to the T direction, and immersing the corresponding weight of absorbing slurry in multiple areas of the white honeycomb. The method of immersing the wave-absorbing slurry is to immerse the whole component. When the impregnation weight is satisfied in zone (A), completion of impregnation requirements in zone (A), the immersion height (h2) is calculated by using formula: (total height)-(height of zone (A)). complete impregnation requirements in zone (A). The total height minus the height of zone (A) is the immersion height (h2). When the impregnation weight is satisfied in zone (B), completion of impregnation requirements in zone (B), the immersion height (h2) is calculated by using formula: (total height)-(height of zone (A)+zone (B)). The hard dipping to the last area meets the final dipping requirements. Each area is set to a corresponding height, and each height requires a different weight.
