NOVELTY - Flame retardant material comprises 1-100 pts. wt. polyether polyol, 20-70 pts. wt. toluene diisocyanate, 0.2-1 pts. wt. nanometer white carbon black, 10-20 pts. wt. deionized water, 5-20 pts. wt. dimethyl methyl phosphonate, 2-8 pts. wt. graphene oxide, 15-30 pts. wt. barium titanate, 1-5 pts. wt. nano-zinc oxide, 1-3 pts. wt. nano-tungsten oxide, 2-8 pts. wt. zinc borate, 0.02-0.4 pts. wt. stannous octoate, 0.03-0.6 pts. wt. triethylene diamine, 0.2-3 pts. wt. organosilicone surfactant and 1-10 pts. wt. sodium bicarbonate. USE - Used as flame retardant material. ADVANTAGE - The flame retardant material has characteristics e.g. low smoke, low poison; has no toxicity; has flame retardancy and wide absorption frequency of absorbed waves. DETAILED DESCRIPTION - Flame retardant material comprises 1-100 pts. wt. polyether polyol, 20-70 pts. wt. toluene diisocyanate, 0.2-1 pts. wt. nanometer white carbon black, 10-20 pts. wt. deionized water, 5-20 pts. wt. dimethyl methyl phosphonate, 2-8 pts. wt. graphene oxide, 15-30 pts. wt. barium titanate, 1-5 pts. wt. nano-zinc oxide, 1-3 pts. wt. nano-tungsten oxide, 2-8 pts. wt. zinc borate, 0.02-0.4 pts. wt. stannous octoate, 0.03-0.6 pts. wt. triethylene diamine, 0.2-3 pts. wt. organosilicone surfactant and 1-10 pts. wt. sodium bicarbonate, where the polyether polyol has hydroxy value of 30-60 mg potassium hydroxide/g. and the isocyanate index of the toluene diisocyanate is 0.60-1.15. An INDEPENDENT CLAIM is also included for preparing the flame retardant material, comprising (i) mixing polyether polyol, dimethyl methyl phosphonate, the above raw materials, nanometer white carbon black, barium titanate, zinc borate, stannous octoate, triethylenediamine, deionized water and organosilicone surfactant, stirring uniformly at room temperature, and carrying out ultrasonic dispersion treatment to obtain first mixture; (ii) adding toluene diisocyanate, nano-zinc oxide, and nano tungsten oxide were added to the initial mixture and ultrasonically stirring for 15-30 minutes, adding graphene oxide and sodium bicarbonate, quickly pouring into the mold for room temperature and foaming for 30-90 minutes to obtain wave absorbing material gel; and (iii) freezing and drying.
