Embodiment 1
[0044] Add 6g of silicone rubber (component A of 184 silicone rubber), 0.6g curing agent (component B of 184 silicone rubber), and 7g of hydrophobic alumina (nano-alumina:micron-alumina=2:5) to 16g of n-decane, and After ultrasonic dispersion and mixing for 20 minutes, a uniform suspension was obtained, which was then evenly coated on the surface of the iron sheet, and quickly placed in a 110°C oven for heating for 30 minutes.
Embodiment 2
[0046] Add 4.6g of silicone rubber (component A of 184 silicone rubber), 0.46g of curing agent (component B of 184 silicone rubber), and 7.2g of hydrophobic alumina (nano-alumina:micron-alumina=3:5) to 16g of n-decane , After ultrasonic dispersion and mixing for 20 minutes, a uniform suspension was obtained, and then evenly coated on the surface of the iron sheet, and quickly placed in a 110°C oven for heating for 30 minutes.
Embodiment 3
[0048] Add 2.5g of silicone rubber (component A of 184 silicone rubber), 0.25g of curing agent (component B of 184 silicone rubber), and 7.2g of hydrophobic alumina (nano-alumina:micron-alumina=1:5) to 18g of n-decane , After ultrasonic dispersion and mixing for 20 minutes, a uniform suspension was obtained, and then evenly coated on the surface of the iron sheet, and quickly placed in a 110°C oven for heating for 30 minutes.
