In order to achieve the purpose, the invention adopts the following technical scheme: the oil-resistant silicone sealant is prepared from the following components in parts by weight:
100 parts of self-crosslinking fluorosilicone

0-50 parts of hydroxyl-terminated silicone and 0-40 parts of methyl-terminated silicone
0-40 parts of methyl-terminated fluorosilicone and 10-30 parts of fumed silica
30-70 parts of superfine calcium carbonate and 0.2-5 parts of catalyst
The self-crosslinking fluorosilicone has the following molecular structure:
R1[OSi(CH3)(CH2CH2CF3)]x[OSi(CH3)R2]y[OSi(CH3)(CH=CH2)]z OR1
wherein R is1is-CH3、-C2H5、-C5H6、-Si(CH3)3、- Si(CH3)2(CH=CH2)、- Si(CH3)2(C6H5)、- Si(CH3)2[CH2CH2Si(OCH3)3]or-Si (CH)3)2[CH2CH2Si(OC2H5)3]；
R2is-CH2CH2Si(OCH3)3or-Si (CH)3)2[CH2CH2Si(OC2H5)3](ii) a x is an integer of 20 to 2000, y is an integer of 1 to 200, and z is an integer of 0 to 100.
Further, the self-crosslinking fluorosilicone is prepared by the following steps: reacting 100 parts of vinyl fluorosilicone oil with 1-20 parts of trimethoxy silane or triethoxy silane under the action of 0.1-2 parts of platinum catalyst at 60-130 ℃ for 0.1-5 h, and removing unreacted trimethoxy silane or triethoxy silane in vacuum to obtain the self-crosslinking fluorosilicone containing trimethoxy or triethoxy.
Furthermore, the hydroxyl-terminated fluorosilicone is alpha, omega-dihydroxymethyl trifluoropropyl polysiloxane with the viscosity of 500-10000 mPas.
Furthermore, the hydroxyl-terminated silicone is alpha, omega-dihydroxy dimethylpolysiloxane with the viscosity of 200-10000 mPas.
Further, the methyl fluorosilicone is 200-5000 mPas of trimethyl silicon end-capped polymethyl trifluoropropyl siloxane.
Further, the methyl-terminated silicone is trimethylsilyl-terminated polydimethylsiloxane with the viscosity of 200-5000 mPas.
Further, the catalyst is at least one of dibutyltin dilaurate, dioctyltin dilaurate, monobutyltin oxide, dibutyltin acetate and stannous octoate.
Furthermore, the superfine calcium carbonate is above 2000 meshes.
Further, all raw materials are subjected to water removal treatment or drying treatment, wherein the fumed silica and the ultrafine calcium carbonate are required to be dried in an oven with the temperature of 150 ℃ for more than 4 hours.
Mixing self-crosslinking fluorosilicone, hydroxyl-terminated silicone, methyl-terminated silicone and methyl-terminated fluorosilicone, heating to 50-100 ℃, adding fumed silica and ultrafine calcium carbonate, uniformly mixing, drying for 1-10 h in vacuum, and adding a catalyst to obtain the milky ointment oil-resistant silicone sealant.
Compared with the prior art, the invention has the beneficial effects that:
the oil-resistant silicone sealant provided by the invention can be used at extremely low temperature (-60 ℃) and high temperature (200 ℃), and has extremely strong bonding force and lasting flexibility.
Because the fluorosilicone macromolecular chain is provided with the crosslinking group, the crosslinking mode is more efficient and uniform compared with the traditional mode of adding the crosslinking agent, so that the cured sealant has better elasticity, strength and oil resistance.
