[0026] n-Butanol 3
[0027] Polyethylene glycol 5
[0028] Chlorinated paraffin 20
[0029] Nano silica 0.2
[0031] Glycerol triglyceride 18; its preparation method is to heat and emulsify the above components, and pack them.
[0032] The prepa...
Embodiment 2
[0036] A kind of butyronitrile regenerated rubber seal ring material, it is made by the raw material of following weight part:
[0037] Nitrile rubber 3345 50, nitrile regenerated rubber 20, antioxidant SP 2, antioxidant BLE 1, stearic acid 1, sulfur powder 0.8, palm wax 1.2, zinc oxide 6, processing aid WB16 1.2, carbon black N550 60, Carbon black N330 35, methyl pentachlorostearate 40, accelerator TMTD 1, accelerator TETD 1, accelerator DM 2, nano calcium carbonate 4, alkyl resorcinol formaldehyde resin 3, maleic anhydride 3 , Plasticizer 4.
