▎ 摘  要

NOVELTY - A silicon-molybdenum co-modified epoxy resin (I) is new. USE - Silicon-molybdenum co-modified epoxy resin is used for wave-absorbing coating and honeycomb used in electronic equipment. ADVANTAGE - The epoxy resin has improved synergistic effect, and ensures the mechanical property of the wave-absorbing honeycomb at high temperature so as to ensure the wave absorbing performance of the honeycomb. DETAILED DESCRIPTION - A silicon-molybdenum co-modified epoxy resin of formula (I) is new, where n and m are each independently selected from an integer of 1-10, R1, R2, R3, R4 are each independently selected from -H, 1-4C substituted or unsubstituted straight-chain alkyl, or 1-4C substituted or unsubstituted branched alkyl. INDEPENDENT CLAIMS are included for following: 1. A method for preparing a silicon-molybdenum co-modified epoxy resin of formula (I). 2. A wave-absorbing coating, which comprises 50-90 pts. wt. silicon-molybdenum co-modified epoxy resin, 3-10 pts. wt. curing agent, 10-40 pts. wt. filler, 3-7 pts. wt. dispersing agent, 0.5-2 pts. wt. leveling agent, 0.8-1.2 pts. wt. accelerator and 1-3 pts. wt. an antifoaming agent. 3. A method for preparing wave-absorbing honeycomb, which involves preparing raw materials according to the formula of the wave-absorbing coating, drying the honeycomb core material, and soaking the dried honeycomb core material in the wave-absorbing coating and drying the impregnated honeycomb core material to obtain an impregnated honeycomb core material, and drying and curing the impregnated honeycomb core material. 4. A wave-absorbing honeycomb used in the manufacture of a thermal radiation detector, a thermal radiation imager or a non-destructive detector.
