Zinc alloy with low-temperature superplasticity, high thermal conductivity and low silica gel corrosion performance and preparation method thereof

The invention discloses a zinc alloy with low-temperature superplasticity, high thermal conductivity and low corrosion performance to silica gel and a preparation method thereof. The preparation method mainly comprises the following steps: selection of components and proportion of the low-temperature superplasticity zinc alloy, smelting preparation of the low-temperature superplasticity zinc alloy, deformation treatment of the low-temperature superplasticity zinc alloy, and returning to a furnace for semi-melting compression molding. The low-temperature lead-zinc and cadmium-zinc alloy has the beneficial effects that 1) compared with traditional low-temperature lead-zinc and cadmium-zinc alloys, the low-temperature lead-zinc and cadmium-zinc alloy is good in flexibility and not prone to brittle fracture, and the quality of the zinc alloy is remarkably improved; 2) the casting temperature of the ornament is lower (410 DEG C or below), the cooling time is short, the corrosion to a silica gel mold is small, the
