▎ 摘  要

NOVELTY - Degradable biological resin-based wave absorbing material comprises 40-45 pts. wt. resin substrate, 5-10 pts. wt. ceramic substrate, 3-5 pts. wt. citric acid, 3-5 pts. wt. iron(II,III) oxide, 10-15 pts. wt. nano graphene, 4-6 pts. wt. coupling agent, and 2-4 pts. wt. dispersant. USE - Used as degradable biological resin-based wave absorbing material. ADVANTAGE - The wave absorbing material: has good wave absorbing performance and mechanical performance; is simple to prepare; and can be produced on large scale. DETAILED DESCRIPTION - INDEPENDENT CLAIM is also included for preparing the degradable biological resin-based wave absorbing material comprisi ng (1) accurately weighing 3-5 pts. wt. citric acid and 3-5 pts. wt. iron(II,III) oxide, mixing with 50-55 parts by volume of water, stirring and mixing for more than 2 hours to obtain mixed solution-1; (2) heating 40-45 pts. wt. resin substrate to 120-180 degrees C, at this temperature, adding 5-10 pts. wt. ceramic substrate, 10-15 pts. wt. nano graphene, 4-6 pts. wt. coupling agent, and 2-4 pts. wt. dispersant, mixing and stirring for more than 1 hour to obtain a mixed solution-2; and (3) cooling the mixed solution-2 to 110-140 degrees C, not stopping stirring during this period, adding mixed solution-1 when it drops to 110-140 degrees C, and continuously mixing and stirring for more than 3 hours.
