Embodiment 1
[0041] A double-sided vacuum aluminizing film process is prepared by the following steps:
[0042] Step 1. Melt 1kg of aluminum wire, add 10g of trilauryl phosphite to mix evenly, keep warm for 40min, cool to below 60°C, carry out vacuum sintering, heat up to 600°C at 5-7°C / min, hold for 2h, and then naturally Cooling to below 60°C to obtain aluminum;
[0043] Step 2: Mix 3 L of 15% zirconium oxychloride aqueous solution with 1.5 kg of chlorinated polypropylene and 0.2 kg of amantadine hydrochloride, and heat to 70° C. for 70 min to prepare a mixed glue. The mass concentration is 1 L of 20% tetraethylammonium chloride aqueous solution was added to the mixed glue solution, heated to 80°C for 20 minutes to prepare a composite glue solution, and the composite glue solution was coated on the substrate, and then heated to 70°C. The horse ray is irradiated, and the radiation dose is 9kGy / h until the water is evaporated to dryness, and the base film is obtained;
[0044] Step 3. On...
Embodiment 2
[0049] A double-sided vacuum aluminizing film process is prepared by the following steps:
[0050] Step 1. Melt 1kg of aluminum wire, add 30g of trilauryl phosphite and mix evenly, keep warm for 40min, cool to below 60°C, carry out vacuum sintering, heat up to 650°C at 5-7°C / min, hold for 2h, and then naturally Cooling to below 60°C to obtain aluminum;
[0051] Step 2: Mix 3 L of zirconium oxychloride aqueous solution with a mass concentration of 5%, 3 kg of chlorinated polypropylene and 0.6 kg of amantadine hydrochloride, and heat to 85° C. for reaction for 50 min to obtain a mixed glue solution. The mass concentration is 10 % tetraethylammonium chloride aqueous solution 2L, added to the mixed glue solution, heated to 50 ° C for 35 minutes to prepare a composite glue solution, coated the composite glue solution on the substrate, and then heated to 80 ° C, while using gamma The ray is irradiated, and the radiation dose is 4kGy / h, until the water is evaporated to dryness, and ...
Embodiment 3
[0057] A double-sided vacuum aluminizing film process is prepared by the following steps:
[0058] Step 1. Melt 1kg of aluminum wire, add 30g of trilauryl phosphite and mix evenly, keep warm for 40min, cool to below 60℃, carry out vacuum sintering, heat up to 600℃ at 5-7℃ / min, and keep warm for 1.5h, then Naturally cooled to below 60°C to obtain aluminum;
[0059] Step 2: Mix 3 L of zirconium oxychloride aqueous solution with a mass concentration of 10%, 2.1 kg of chlorinated polypropylene and 0.5 kg of amantadine hydrochloride, and heat to 80 °C for 60 min to prepare a mixed glue solution. The mass concentration is 1.5L of a 16% aqueous solution of tetraethylammonium chloride was added to the mixed glue, heated to 70°C for 30 minutes to prepare a composite glue, and the composite glue was coated on the substrate, and then heated to 80°C while using Irradiated with gamma rays, the radiation dose was 7kGy / h, until the water was evaporated to dryness, and the base film was obta...
