Organic fluorine oxosilane nanometer freezing sticky resistant coating and preparation process thereof

The invention discloses an organic fluorine oxosilane nanometer freezing sticky resistant coating and a preparation process of the organic fluorine oxosilane nanometer freezing sticky resistant coating. A coating layer comprises a fluorine oxosilane solution and/or hydroxyl-terminated fluorine contained silicone oil, a catalytic agent, polyvinyl acetal, a diluent, a curing agent, a plasticizer, a dispersing agent, an antifoaming agent and nanometer powder. A synthetic process: adding 15-20% of the fluorine oxosilane solution and/or the hydroxyl-terminated fluorine contained silicone oil and 30-36% of the polyvinyl acetal into the 16-30% diluent, adding 0.5-1% of the catalytic agent, adding 2-5% of the plasticizer and 1-2% of the nanometer grade inorganic powder, 0.5-10% of the dispersing agent and 0.5-2% of the antifoaming agent, reacting for 2-4 hours at the temperature of 90 DEG C for ball milling, finally adding 10-20% of the curing agent, and evenly stirring and coating on a surface of a workpiece for roo
