Description
Technical field
The invention belongs to field of metal surface treatment technology, and in particular to a kind of copper strips passivator and its application process.
Background technology
Traditional copper material surface passivating treatment technique mainly includes BTA of inorganic chromate and organic etc..
Because chromating facture contains Cr VI, the use for belonging to high poison, high pollution therefore this technique receives strict limit
System.Most of copper material passivator are all the passivator configured based on BTA in the market, but are easy to occur
Phenomena such as macula lutea, bad resistance to corrosion.

Nickel 0.5-0.7%, fluorine zirconic acid 1.5-2.5%, water surplus.
Described a kind of copper strips passivator, it is characterised in that include the component of following degree：
Mercaptobenzothiazoler 3-4%, Ludox 1.8-2.2%, tartaric acid 3-4%, methenamine 0.6-0.8%, nickel sulfate 0.5-
0.7%th, fluorine zirconic acid 1.8-2.2%, water surplus.
A kind of application process of described copper strips passivator, it is characterised in that：
1）At normal temperatures, the brass band cleaned up is put into passivator and carries out surface passivating treatment, soak time 15-20
Minute；
2）Brass band is put into drying tunnel and carries out heating drying, first stage drying temperature is 40-50 DEG C, 5-10 points of drying time
Clock, 50-60 DEG C of second stage, drying time 5-10 minutes, 60-100 DEG C of phase III, drying time 10-15 minutes, fourth order
