NOVELTY - Grafted graphene heat dissipation silicone composition, comprises 30-60 wt.% silicone rubber, 5-15 wt.% grafted graphene powder, 1-5 wt.% modified carbon nanotube powder, 0.3-3 wt.% crosslinking catalyst, 3-10 wt.% curing agent, 10-50 wt.% solvent, 0.1-2 wt.% adhesive. USE - Used as grafted graphene heat dissipation silicone composition ADVANTAGE - The water-absorbing expansion elastomer has stable performance, better compatibility of salt resistant water-absorbing resin and polymer elastomer, small expansion change after repeatedly absorbing water, has high strength, better salt resistance and processing performance, which can satisfy the requirement of simple production technique and low production cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high-strength, salt-resistant water-swellable elastomer comprises thinly wrapping the elastomer on the internal mixer, introducing water-absorbing resin, nonionic surfactant, rubber cross-linking agent, barium sulfate and zinc oxide, anti-aging agent, stearic acid, liquid nitrile, tackifying resin, spray black carbon black and white carbon black, organic peroxide, bentonite, vulcanizing agent and accelerator are mixed uniformly to obtain elastomer compound, introducing the elastomer compound on a flat vulcanizer at a pressure of 7-10 MPa and a vulcanization temperature of 100-170degrees Celsius for 10-40 minutes.
