Embodiment 1
[0023] The production method of the copper-aluminum composite decorative material of the present embodiment comprises the following steps:
[0024] (1) One side surface of the T2 copper plate with a width of 1200mm and a thickness of 1.0mm is electroplated with tin to obtain a copper plate blank with a tin-plated layer, and the thickness of the tin-plated layer is 0.003mm; Tin sulfamate, 0.8% sulfuric acid, 0.9% AlCl 3 and 6% trisodium phosphate, the solvent is water; the temperature of electroplating tin is 200°C, the voltage is 380V, the current is 600A, and the current density is 0.5A / dm 2 ;
[0025] (2) Facing the aluminum plate with the tin-plated layer of the copper plate blank with the tin-plated layer, it is hot-rolled and compounded with 1060 aluminum plates with a thickness of 8 mm, annealed and heat-treated, and cold-rolled to obtain a copper-aluminum composite decorative material; the temperature of the hot-rolled compound is 300° C. The rolling speed of hot-roll...
