▎ 摘　　要

NOVELTY - An electronic device comprises heat conducting resin comprising 100-150 pts. wt. nitrile rubber, 50-100 pts. wt. natural resin, 20-30 pts. wt. boron modified phenolic resin, 1-15 pts. wt. expanded graphene, 2-10 pts. wt. vulcanization agent and 1-30 pts. wt. plasticizer. USE - Electronic device. ADVANTAGE - The device is made up of resin having high strength, low specific gravity, and good heat conducting performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the resin comprising taking nitrile rubber, natural resin, boron modified phenolic resin, and expanded graphene for mixing at 60-70 degrees C for 5-30 minutes, raising to 75-85 degrees C for 5-30 minutes, adding vulcanization agent and plasticizer, and pressure forming at 150-170 degrees C and 10-25 MPa for 10-60 minutes.
