The present invention discloses an
environmental protection ashing treatment process of calendaring
copper foil. The
environmental protection ashing treatment process comprises
degreasing washing, roughening
electroplating, curing
electroplating,
nickel alloy electroplating,
zinc electroplating, chromate
passivation treatment,
silane treatment and the like. According to the present invention, after electrochemical
degreasing, roughening and curing treatment (roughening and curing can be selected more than two times according to the requirement) Cu grain electrodeposition are performed on the calendaring
copper foil, the nano-scale
nickel alloy is electrodeposited under the acidic condition, the
thin metal zinc layer is electroplated, and finally the chromate
passivation treatment is performed and the
silane coupling agent is uniformly sprayed on the surface; As, Sb, Cd and other toxic and harmful metals are not added, and the
alloy system electrodeposition and other relatively simple processes are used to treat the process; and under the optimization of the process parameters, the
environmentally friendly surface treated
copper foil with characteristics of good performance, meeting of FPC production requirements, gray appearance of gray, no
toxicity and no harm can be obtained.
