[0027]Mix and soak the pitch-based carbon fiber with a mass concentration of 2 g / L dopamine solution at a mass ratio of 1:100 for 20 minutes, then take out the soaked pitch-based carbon fiber, drain the water, and obtain the pre-treated pitch-based carbon fiber, and then press the parts by weight. 40 parts of pretreated pitch-based carbon fibers, 150 parts by mass of 60% ethanol solution were added in sequence to the reaction kettle, under the condition of temperature of 55 °C and rotation speed of 400 r / min, constant temperature stirring and mixing for 30 minutes, and then stirring at constant temperature. Next, add tetraethyl orthosilicate with 0.5 times the mass of the pretreated pitch-based carbon fiber into the reaction kettle. After the addition of ethyl orthosilicate ends, continue to stir the reaction at constant temperature for 60 min, and then filter the material in the reaction kettle to obtain a filter cake, which is then used The filter cake was washed with deioniz...

[0031] The serpentine asbestos fiber and deionized water were prepared into a serpentine asbestos fiber slurry with a mass fraction of 8%, and then the serpentine asbestos fiber slurry was transferred to a dynamic water filter, and the speed was 800r / min. The serpentine asbestos fiber pulp is sieved to obtain the sieved residue, which is the pretreated serpentine asbestos fiber; and then in parts by weight, 320 parts of the pretreated serpentine asbestos fiber are taken in turn, and the solid content of 120 parts is 30 parts by weight. % Neoprene latex, 30 parts of pitch-based carbon fiber, 5 parts of sulfur, 5 parts of vulcanization accelerator TMTD, 6 parts of nano-zinc oxide, 1.5 parts of antioxidant RD, combining sulfur, vulcanization accelerator TMTD, nano-zinc oxide and antioxidant RD After mixing with water with 20 times the mass of sulfur, ultrasonically disperse it for 45min under the condition of ultrasonic frequency of 50kHz to obtain a suspension of auxiliary agent,...
