Description
Technical field
The present invention relates to field of metal surface treatment technology, specially a kind of water-soluble high-efficient nickel plating antirust sealer and its
Compound method.
Background technology
Many steel-iron components, for antirust and decoration needs, widely used nickel plating technology.Nickel coating on steel-iron components is
Cathodic coating, only when coating does not have hole, can just play complete mechanical protection effect.And the imporous thickness one of nickel plating
As more than 24 microns, price is high, and most parts are extremely difficult to.At present, thin bright nickel technique is generally plated using copper facing bottoming again.For
Cost is reduced, bright nickel coating only has 4-5 microns, unavoidably there is hole.Corrosive medium is first rotten by copper substrate by hole
Erosion, and then by iron matrix corrosion, coating decay resistance is not good, often need to be handled to improve its corrosion resistance with antirust sealer
Energy.
Existing frequently-used nickel plating antirust sealer is divided to two major classes:One class is aqueous rustproof sealer.Existing many Chrome-free rings
Nickel plating antirust sealer is protected to close for thin nickel dam, but majority can only meet neutral salt spray test requirement in 24 hours.It is another kind of to be
Oil base antirust sealer, has preferably a more preferably antirust sealing effect than aqueous rustproof sealer, but there is smell, it is greasy, safe
The problems such as.
