Embodiment 1-4
[0025] The preparation method of the high-pressure and high-temperature resistant high-resistance cooling pipeline rubber of the present invention is as follows: 1) kneading: after weighing each material according to the mass ratio, add the materials except the vulcanizing agent into the kneader and knead evenly; 2) plasticizing : Add the mixed rubber in the internal mixer, add the vulcanizing agent to make the mixed rubber for use; 3) Vulcanization: vulcanize the mixed rubber on the vulcanizing machine, the vulcanization temperature is 170 ℃, the pressure is 10 MPa, and the time is After 10 minutes, the glue is discharged and cooled, and the rubber for the transmission pipeline of the low-resistance flame-retardant fuel cell is obtained after the glue is discharged.
[0026] The raw material ratios in Examples 1-4 are shown in Table 1. Wherein, the polypyrrole nanotube composite flame retardant is obtained according to the preparation method of Example 5, the conductive agent...
