NOVELTY - Polyurethane ferrite complex wave absorbing porous material comprises 100 pts. wt. polyether polyol, 30-60 pts. wt. toluene diisocyanate, 0.05-0.4 pts. wt. nanocarbon sol, 0.2-0.5 pts. wt. nano white carbon black, 10-20 pts. wt. deionized water, 5-25 pts. wt. dimethyl methyl phosphate, 2-8 pts. wt. graphene oxide, 10-20 pts. wt. ferrite, 2-10 pts. wt. silicon carbide, 2-8 pts. wt. zinc borate, 0.02-0.4 pts. wt. stannous octoate, 0.03-0.6 pts. wt. triethylenediamine, 0.2-3 pts. wt. silicone surfactant and 2-8 pts. wt. sodium bicarbonate. USE - Used as polyurethane ferrite complex wave absorbing porous material. DETAILED DESCRIPTION - Polyurethane ferrite complex wave absorbing porous material comprises 100 pts. wt. polyether polyol, 30-60 pts. wt. toluene diisocyanate, 0.05-0.4 pts. wt. nanocarbon sol, 0.2-0.5 pts. wt. nano white carbon black, 10-20 pts. wt. deionized water, 5-25 pts. wt. dimethyl methyl phosphate, 2-8 pts. wt. graphene oxide, 10-20 pts. wt. ferrite, 2-10 pts. wt. silicon carbide, 2-8 pts. wt. zinc borate, 0.02-0.4 pts. wt. stannous octoate, 0.03-0.6 pts. wt. triethylenediamine, 0.2-3 pts. wt. silicone surfactant and 2-8 pts. wt. sodium bicarbonate, where the hydroxy value of polyether polyol is 30-60 mgKOH/g and the isocyanate index of toluene diisocyanate is 0.60-1.15. An INDEPENDENT CLAIM is also included for preparing the polyurethane ferrite complex wave absorbing porous material, comprising mixing polyether polyol, dimethyl methyl phosphate, nano carbon sol, nano white carbon, ferrite, silicon carbide, zinc borate, stannous octoate, triethylenediamine, deionized water and silicone surfactant, stirring at room temperature and dispersing by sonication to obtain the first mixture; adding toluene diisocyanate to the primary mixture, ultrasonically stirring for 5-10 minutes under the condition of heating, adding graphene oxide and sodium bicarbonate, adding into the mold at room temperature and foaming for 30-90 minutes to obtain wave absorbing material gel; and freeze-drying the wave-absorbing material gel.
