Abstract
The utility model discloses an express way fence with zinc thermal-spraying, aluminum thermal-spraying and polyester-based coupling coating, belonging to the field of means of transportation. A coupling coating of multi-coat is positioned on the surface of the fence board, the column, the column cap and the connection materials and the structure of the multi-coat is(from interior to exterior): a zinc thermal-spraying coating, an aluminum thermal-spraying or aluminum alloy coating and a polyester-based thermoplastic powder coating. The utility model has the advantages that: the combination of the zinc thermal-spraying and the aluminum thermal-spraying can take advantage of the good protection effect of the sprayed zinc and the low cost of the sprayed aluminum, thereby, the device is of good erosion proof effect and low cost.
Description
Technical field
The utility model relates to a kind of freeway guardrail, is specifically related to the freeway guardrail of the aluminium-plated polyester composite coating of a kind of hot spray painted zinc heat, belongs to field of traffic facilities.
Background technology
What means of transportation anti-corrosion protections such as present China freeway guardrail mainly adopted is the form of galvanizing or galvanizing plastic-blasting; the erosion resistance of guardrail has had certain guarantee; but can produce a large amount of waste water,waste gas and industrial residue in the hot dip galvanizing process process; seriously pollute environment, endangering people's life.In the application process in nearly ten years of galvanizing plastic-blasting guardrail, also find many problems, as plastic-blasting layer under abominable corrosive environment come off very soon, zinc coat consumes reduced thickness rapidly, not only destroyed the decorative effect of guardrail, the security protection of returning guardrail has caused hidden danger.
The metal thermal spraying technical development is morning, and the hot spray painted zinc coating is external a kind of cathodic protection coatings of using the earliest, and its phase of effectively protecting generally can reach 20-30.Hot spray painted zinc is compared with galvanizing has certain advantage, has avoided the serious environmental pollution, and just hot spray painted zinc causes construction cost to rise owing to the zinc valency is high.
The aluminium-plated technology of heat also has certain applying at present, and aluminium becomes the stronger state of activation of elecrtonegativity in spraying process, can play the cathodic protection effect to steel substrate preferably.Though the cathodic protection effect of aluminium generally is not as good as the high effect of zinc performance area, because the aluminium price is low, its construction cost is also lower, and use in market bigger prospect.
Summary of the invention
The purpose of this utility model provides the freeway guardrail of the aluminium-plated polyester composite coating of a kind of hot spray painted zinc heat.Be in order to solve the shortcoming that galvanizing plastic-blasting and hot spray painted zinc and hot aluminium-plated freeway guardrail exist.
The utility model is achieved through the following technical solutions: the freeway guardrail of the aluminium-plated polyester composite coating of a kind of hot spray painted zinc heat, comprise guardrail board, column, cap and connector, it is characterized in that at guardrail board, column, cap and connector guardrail substrate surface it being the composite coating of the overbrushing layer structure of combining closely with it; The composite coating of overbrushing layer structure is from inside to outside successively: hot spray painted zinc layer, the aluminium-plated or aluminium alloy layer of heat, pure polyester thermosetting powder coating layer.
The thickness of described hot spray painted zinc layer is 10-40 μ m.
Described heat thickness aluminium-plated or aluminium alloy layer is 20-60 μ m.
The thickness of described pure polyester thermosetting powder coating layer is 40-120 μ m.At least the material that contains following a kind of character in the pure polyester thermosetting powder coating: ultra-violet absorber, antioxidant, polytetrafluoroethylene (PTFE), glass fiber, sheet color stuffing, nano material.
Above-mentioned freeway guardrail comprises guardrail board, column, cap and connector.
Above-mentioned guardrail board comprises various forms, as various waveform beam slabs, various frame guardrail, rectangular slab etc.
Above-mentioned column comprises various forms, as pipe, square tube, H shaped steel, L shaped steel etc.
Above-mentioned connector comprises various non-corings, carriage, bolt and nut etc.
Above-mentioned cap comprises the various forms supporting with column, as circular, taper, also can have other members, as light installations, fluorescent sheet, reflector etc.
The hot spray painted zinc layer relies on its cathodic protection effect, function of shielding performance antisepsis emphatically at bottom.Hot aluminium-plated or aluminium alloy layer then mainly plays the shielding action that stops the corrosive medium infiltration, also brings into play its cathodic protection effect simultaneously.Contain multiple auxiliary agent in the polyester powder coating of external coating, the decoration beautification function is not only being brought into play in coating hardness height, strong, the difficult infiltration of coating compactness raising corrosive medium of ageing-resistant ability, also fully plays the protective action of mask erosion erosion medium resistance.Three road coatings organically combine, and give full play to the advantage of each self-structure and performance, have realized efficient protection, compare with the galvanizing plastic-blasting to have good superiority.
Hot-spraying coating of the present utility model can be realized by existing thermal spraying apparatus such as commercially available arc pistol, flame gun, plasma spray gun or quick-fried automatic doubler surface glouer.
The beneficial effects of the utility model are; heat is aluminium-plated to be combined with hot spray painted zinc; giving full play to spray zinc protects and the low mutual supplement with each other's advantages effect of aluminium-plated cost; product had both had good anti-corrosion protection ability; have certain cost competitive advantage again, the utlity model has better market prospect and economic benefit.
Description of drawings:
Accompanying drawing is the structural representation of the utility model guardrail product composite coating.
Among the figure: 1, guardrail steel substrate, 2, hot spraying zinc layer, 3, hot spraying aluminium lamination 4, pure polyester thermosetting powder coating coating.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure, after guardrail steel component base material 1 surface being carried out the degreasing and rust removal processing, adopt the arc pistol hot spray painted zinc, form hot spraying zinc layer 2, thickness 10-20 μ m; Use arc pistol heat aluminium-plated again, form hot spraying aluminium lamination 3, thickness 20-30 μ m; Workpiece is reached the standard grade and is carried out powder coating and their application then, and spraying contains the pure polyester thermosetting powder coating of 0.5% ultra-violet absorber and 0.4% antioxidant, and 200-220 ℃ solidifies 15min, form pure polyester thermosetting powder coating coating 4, thickness 70-100 μ m.
After testing, face coat hardness surpasses 2H, and salt spray test 2000h rear surface non-corroding phenomenon is at irradiation level 1074 ± 50W/m
2Condition under, the accumulation total radiation energy 4.639 * 10
6Kj/m
2Artificial accelerated weathering test after, do not see obvious aging phenomenon.
