Embodiment 1
[0035] The present invention can be used for the preparation method of the adhesive of viton bonding comprising the following steps:
[0036] (1) Get the following components by mass:
[0037] Viton raw rubber 100
[0038] acid absorber 11
[0039] Filler 16
[0040] paint 5
[0041] Vulcanization system 2.5;
[0042] Wherein, the fluororubber raw rubber is FPM2603, and the acid absorbing agent is composed of 3 parts by mass of Ca(OH) 2 + 8 parts by mass of MgO, the filler is 15 parts by mass of diatomite + 1 part by mass of calcium silicate, the pigment is chrome green, and the vulcanization system is 0.5 parts by mass of BPP + 2 parts by mass of bisphenol AF. Acetone is selected as the organic solvent, and acetic acid is selected as the organic acid.
[0043] (2) Open refining:
[0044] The raw rubber is thinly passed 6 times, and then Ca(OH)2, MgO; diatomaceous earth, chrome green; calcium silicate, BPP, bisphenol AF are added in sequence. After adding the material,...

[0052] acid absorber 11
[0053] Filler 16
[0054] Pigment 0
[0055] Vulcanization system 2.5;
[0056] Wherein, the fluororubber raw rubber is FPM2603, and the acid absorbing agent is composed of 3 parts by mass of Ca(OH) 2 + 8 parts by mass of MgO, the filler is 1 part by mass of calcium silicate + 15 parts by mass of carbon black N990, and the vulcanization system is 0.5 parts by mass of BPP + 2 parts by mass of bisphenol AF.
Embodiment 3
[0058] The present embodiment is with embodiment 1 except following feature:
[0059] Get the following components by mass:
[0060] Viton raw rubber 100
[0061] acid absorber 10
[0062] Filler 26
[0063] paint 2
[0064] Vulcanization system 2.1;
[0065] Wherein, the fluororubber raw rubber is FPM2603, and the acid absorbing agent is composed of 4 parts by mass of Ca(OH) 2 + 6 parts by mass of MgO, the filler is 1 part by mass of calcium silicate + 25 parts by mass of barium sulfate, the pigment is chrome green, and the vulcanization system is 0.5 parts by mass of BPP + 1.6 parts by mass of bisphenol AF. The ratio of acetone to the total mass of the fluororubber raw rubber, acid absorbing agent, filler, pigment, and vulcanization system is 1.8:1, and the organic acid is oxalic acid in an amount of 1% of the mass of acetone.
