Description
Technical field
The utility model is related to a kind of coat of metal, more particularly to the safeguard structure that a kind of aluminium alloy non-chromium is passivated.
Background technology
Currently, before application is carried out to metal works, the surface of metal works can all be handled, applies binder course,
To improve the physical property and chemical property of metal works, and then protect metal works.At present, to the surface treatment of metal works
Chromaking processing is used, i.e., adheres to chromaking binder course in metal surface.However, due in chromaking processing procedure, containing phosphorus and
Heavy metal, so that can be to the mankind and environmental danger, environmental-protecting performance is poor.
China Patent No.：201620029909.4 disclosing a kind of safeguard structure of aluminium alloy non-chromium passivation, gold is arranged at
The surface of metal work-pieces, at least includes：Binder course, is attached to surface of workpiece, the binder course does not include phosphorus and chromium, and serves as reasons
Inorganic matter and the fine and close tridimensional network of macromolecule resin formation, the film weight of the tridimensional network is every square metre of 0.1-
0.2g；Overcoat, is arranged on the binder course, is formed by macromolecule resin by electrophoresis or electrostatic spraying, and its thickness is
10 μm~80 μm.The design is chromiumfree conversion binder course for three-dimensional network structure, the powder of resin and application in overcoat
There is preferable crosslinked action, chromaking overcoat, and chromiumfree conversion binder course can be replaced, it is not phosphorous, without heavy metal, prepared
Without residue, non-wastewater discharge in journey, be conducive to environmental protection；But, the binder course and overcoat that surface of workpiece is set exist
Easily collided with transport or installation process bad, cause the metal works of inside to be exposed, reduce the use longevity of metal works
Life.
Utility model content
Therefore, for it is above-mentioned the problem of, the utility model provides a kind of safeguard structure of aluminium alloy non-chromium passivation, and it is main
Surface of workpiece is set in the prior art binder course and overcoat is solved easily to collide with transport or installation process
It is bad, cause the metal works of inside to be exposed, the problem of reducing the service life of metal works.
To achieve the above object, the utility model employs following technical scheme：A kind of protection of aluminium alloy non-chromium passivation
Structure, including it is attached to the combination of the inorganic matter of surface of workpiece and the fine and close tridimensional network of macromolecule resin formation
It is provided with the overcoat that macromolecule resin is formed by electrostatic spraying, the overcoat and is provided with layer, the binder course
The cushion hit for absorbing external, the cushion are provided with foam metal layer, the outer surface of the foam metal layer
On be provided with metal level.
Further, the cushion includes the block rubber that at least two block gaps are set, the upper table of the foam metal layer
Face sets fluted, and the block rubber is embedded in groove, there is interval between the metal level and foam metal layer.
Further, a plurality of diameter identical holes are offered on the metal level.
Further, the outer surface of the metal level is coated with a strata tetrafluoroethene.
By using preceding solution, the beneficial effects of the utility model are：The protection knot of this aluminium alloy non-chromium passivation
Structure is by setting layer of metal layer in the outside of overcoat, for preventing metal works from being bumped in carrying or installation process
Overcoat and binder course, so as to increase the service life of metal works, cushion plays a part of buffering in collision process, subtracts
Few impulsive force is damaged to the binder course of internal layer, and foam metal layer has further functioned as damping, absorbs the effect of impact energy；Enter
One step, block rubber has stronger cushioning effect, there is interval between metal level and foam metal layer so that metal level is received
It is preferential by block rubber damping after shock, then pass through foam metal layer damping, impulsive force of the effective neutralizing to metal works；Enter
One step, a plurality of diameter identical holes are offered on metal level, play a part of mitigating weight so that metal works are in transport
During it is more convenient；Further, the outer surface of metal level is coated with a strata tetrafluoroethene so that metal level it is corrosion-resistant
Property, sealing, anti-aging endurance strengthen, prevent metal level be oxidized, increase metal level service life.
Brief description of the drawings
Fig. 1 is the cross section structure diagram of the utility model embodiment.
Embodiment
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
The utility model embodiment is：
