Embodiment 1

[0028] Weigh 50 grams of BP2000 superconducting carbon black and place it in a 1000ml four-necked flask with a stirring device. Weigh 12.0 grams of trimethylsilanol, add 400ml of 95% ethanol to make a solution, stir evenly and pour it into a four-necked flask. Heat the four-necked flask and let the ethanol stably reflux for about 4 hours while stirring. The carbon black and the ethanol solution in the four-necked flask were suction filtered under reduced pressure, the ethanol was recovered, and the modified carbon black obtained was placed in an oven, and the solvent ethanol was dried at 105°C to 110°C under blast conditions. Store in a desiccator after cooling to room temperature for later use.

Embodiment 2

[0030] Weigh 50 grams of BP2000 superconducting carbon black and place it in a 1000ml four-necked flask with a stirring device. Weigh 10.4 grams of dimethyldiethoxysilane and add 450ml of 95% ethanol to make a solution. Pour the solution into a four-necked flask, heat the four-necked flask, and stir the ethanol to stabilize reflux for about 4 hours. The carbon black in the four-neck bottle and the ethanol solution are filtered under reduced pressure and the ethanol is recovered. The obtained modified carbon black is placed in an oven, and the solvent ethanol is dried at 105°C to 110°C under blast conditions, and is cooled to room temperature and stored in a desiccator for use.

Embodiment 3

[0032] Weigh 50 grams of BP2000 superconducting carbon black and place it in a 1000ml four-necked flask with a stirring device. Weigh 15.0 g of trimethylsilanol and add 400 ml of 95% ethanol to make a solution. Pour the solution into a four-necked flask, heat the four-necked flask, and stir the ethanol to stabilize reflux for about 4 hours. The carbon black in the four-neck bottle and the ethanol solution are filtered under reduced pressure and the ethanol is recovered. The obtained modified carbon black is placed in an oven, and the solvent ethanol is dried at 105°C to 110°C under blast conditions, and is cooled to room temperature and stored in a desiccator for use.

Abstract

The invention discloses a modification processing method of a high structure superconducting carbon black BP2000. According to the weight ratio, the prescription of the modification processing method is 20 parts of the high structure superconducting carbon black BP2000, 100 parts to 200 parts of ethanol and 2 parts to 7 parts of organic silicon reagent. The method of the invention overcomes the problem that mixed and linked adhesive is seriously tackified when the carbon black is added into peroxide vulcanized rubber, thus leading difficult process and normal vulcanization; in addition, the method of the invention is simple, has low cost and is in favor of industrialized production.
