Embodiment 1
[0038] formula:
[0039] Bisphenol A type cyanate prepolymer (pale yellow viscous liquid) 100 parts by weight
[0040] Graphene 5 parts by weight
[0041] KBM-403 silane coupling agent 1 weight
[0042] Preparation Process:
[0043] 1. Weigh 100 parts of cyanate resin into a three-necked flask, and heat it at (70-80)°C to make it a flowing liquid.
[0044] 2. Control the speed of the mixer (200-250) r / min, add 1 part of heavy coupling agent to the three-necked flask, and stir evenly.
[0045] 3. Add 0.5 parts by weight of graphene, stir evenly and continue to stir for 60 minutes to obtain cyanate resin A.
[0046] 4. Pour the remaining 4.5 parts of heavy graphene into the non-interventional gravity disperser cup, add cyanate resin A, and tighten the cup lid.
[0047] 5. Start the non-interventional gravity disperser, set the revolution speed to 1500r / min, the rotation speed to 3000r / min, and control the dispersion time to 15min to obtain graphene-modified cyanate resin.
