Abstract
The utility model discloses a kind of for transformer inner wall of oil tank oil resistant and does not produce hydrogen coating structure, is coated with prime coat in metallic substrate surface；Intermediate primer layers are coated in primer coat surface；Top coat layer is coated on intermediate primer layers surface；Oil resistant top coat layer is coated in finishing coat layer surface.The prime coat is epoxy primer coating；The intermediate primer layers are lacquer coat among polyurethane；The top coat layer is polyurethane finish coating；The oil resistant top coat layer is butyral resin coating.The utility model utilizes the flexibility and flexibility of butyral resin, and making oil tank of transformer inside coating is not in the phenomenon that falling off and produce hydrogen under the conditions of the Long Term Contact with transformer oil.Anti-corrosion anti ageing property is good, bonding force is strong, it is anti-collide with, impact resistance, effectively reduce oil tank of transformer and deform under external force, damage and easy for construction.
Description
Technical field
The utility model relates to a kind of coating structures, and in particular to a kind of for transformer inner wall of oil tank oil resistant does not produce hydrogen painting
Layer structure.
Background technique
Inner wall of oil tank is contacted with transformer oil for a long time when due to transformer station high-voltage side bus, to the resistance to of inner wall of oil tank paint coatings
Oily, corrosion-resistant and insulation performance proposes higher requirement.The protective coating of conventional transformer inner wall of oil tank is only in metal base
Surface coat one layer of epoxy primer coating, although have certain antiseptic property, under the long period of soaking of transformer oil,
Protective performance is far from the requirment, and coating reacts with transformer oil and is easy output hydrogen ion, influences the insulation of transformer
Performance.
Utility model content
The purpose of this utility model is to disclose a kind of for transformer inner wall of oil tank oil resistant not producing hydrogen coating structure, by
The original coating surface of transformer oil chamber interior wall coats one layer of butyral resin coating, make full use of butyral resin flexibility and
Flexibility, making oil tank of transformer inside coating is not in fall off and produce showing for hydrogen under the conditions of the Long Term Contact with transformer oil
As.
To realize the purpose of this utility model, the technical solution adopted is that:
A kind of for transformer inner wall of oil tank oil resistant does not produce hydrogen coating structure, is coated with prime coat in metallic substrate surface；
Intermediate primer layers are coated in primer coat surface；Top coat layer is coated on intermediate primer layers surface；Oil resistant is coated in finishing coat layer surface
Top coat layer.
The prime coat is epoxy primer coating；The intermediate primer layers are lacquer coat among polyurethane；The top coat layer is
Polyurethane finish coating；The oil resistant top coat layer is butyral resin coating.
The beneficial effect that the utility model reaches is: using the flexibility and flexibility of butyral resin, making transformer oil
Chamber interior wall coating is not in the phenomenon that falling off and produce hydrogen under the conditions of the Long Term Contact with transformer oil.Anti-corrosion anti ageing property
It is good, bonding force is strong, it is anti-collide with, impact resistance, effectively reduce oil tank of transformer and deform under external force, damage and construction party
Just.
Detailed description of the invention
Fig. 1 is that a kind of for transformer inner wall of oil tank oil resistant of the utility model does not produce hydrogen coating structure schematic diagram.
Specific embodiment
A kind of coating structure that for transformer inner wall of oil tank oil resistant does not produce hydrogen of the utility model is done further referring to Fig.1
Explanation.
A kind of for transformer inner wall of oil tank oil resistant does not produce hydrogen coating structure, is coated with prime coat on 1 surface of metal base
2；Intermediate primer layers 3 are coated in primer coat surface 2；Top coat layer 4 is coated on 3 surface of intermediate primer layers；It is coated on 4 surface of top coat layer
There is oil resistant top coat layer 5.
The prime coat is epoxy primer coating；The intermediate primer layers are lacquer coat among polyurethane；The top coat layer is
Polyurethane finish coating；The oil resistant top coat layer is butyral resin coating.
The primer coating is two-component epoxy iron red shop primer, plays extraordinary antisepsis to metal base.
The intermediate lacquer coat is dual-component polyurethane intermediate coat, plays the role of increasing anti-corrosion and reinforces adhesive force.
The topcoat is dual-component polyurethane enamel paint, plays the role of protecting priming paint anti-aging, and can pass through addition
Various pigment are tuned into colored finishing coat, sufficiently meet the aesthetic requirements that transformer uses client.
The oil resistant topcoat is one-component butyral resin paint, which makes oil tank of transformer inside coating
It avoids falling off in transformer oil immersion and does not produce hydrogen.
