Embodiment 1
[0052] This embodiment provides a fluorine rubber compound prepared from the following components:
[0053]
[0054]
[0055] The preparation method of the modified N762 carbon black filler is as follows: after mixing the carbon black N762 with 1 to 3% of a four-functional silane coupling agent for 2 hours, and then airtightly storing it for 12 hours;
[0056] The preparation method of described fluororubber compound rubber is as follows:
[0057] (1) According to the formula ratio, bisphenol AF, BPP, CGUF201, magnesium oxide 170, ultrafine calcium hydroxide NICC5000, WS280, and A54 are pre-prepared according to the amount of 10kg of raw rubber per vehicle, and are sealed and mixed in the container to prevent auxiliary Agent failure;
[0058] (2) Shear and mix CGFT600A and FKM26H01M in the state of open kneading, so that the two are evenly kneaded together, parked, and stored in an airtight manner; in the pressurized internal mixer, add raw rubber after mixing Mixing t...
