▎ 摘 要
NOVELTY - A dust-proof rubber composition comprises 50-100 pts. wt., preferably 75 pts. wt. silicone rubber, 20-60 pts. wt., preferably 40 pts. wt. fluororubber, 10-20 pts. wt., preferably 15 pts. wt. cellulose, 10-20 pts. wt., preferably 15 pts. wt. graphene, 15-20 pts. wt., preferably 17 pts. wt. silicon micropowder, 1-5 pts. wt., preferably 3 pts. wt. vulcanizing agent, 3-15 pts. wt., preferably 8 pts. wt. silane coupling agent, 10-20 pts. wt., preferably 15 pts. wt. antiaging agent, and 10-20 pts. wt., preferably 15 pts. wt. reinforcing agent. USE - Dust-proof rubber composition is used for automobiles. ADVANTAGE - The dust-proof rubber composition has low volume resistivity and hardness, and excellent high/low-temperature resistance, solvent resistance, oil resistance, and aging resistance. The volume change rate is 1.2% (while the volume change rate of only silicone rubber is 25% and only fluorosilicone rubber is 3%). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of rubber composition, which involves carrying out low-temperature plastication of silicone rubber and fluororubber in an open mill, mixing with other components, resting the mixture for 15 hours, and curing at 1150 degrees C for 20 minutes and at 160 degrees C for 6 hours.
