Corrosion-resisting air-conditioning fin material used for marine product cultivation workshop and preparation method thereof

[0028] The weight percentage of the elements forming the material of the base layer is:

[0029] Silicon 7, copper 1.7, manganese 3.0, iron 1.2, lanthanum 0.3, zirconium 0.04, strontium 0.14, titanium 0.39, vanadium 0.13, aluminum balance.

[0030] The material of the heat conduction layer is graphene, and the thickness of the first heat conduction layer and the second heat conduction layer is 100 microns;

[0031] The preparation method comprises the steps of:

[0032] The various components of the base layer and the refining agent were melted in an electric furnace and cast into aluminum ingots. After casting, the temperature was lowered to 550°C at a rate of 132°C / hour and kept for 8 hours;

[0033] Then, at a rate of 120°C / hour, the temperature was lowered to 250°C, and the temperature was kept for 8 hours;

[0034] Then heat up to 440°C at a rate of 70-°C / hour, and keep warm for 3 hours;

[0035] Then cool down to 160°C at a rate of 80°C / hour and keep warm for 3 hours;...
