The inner coating of the composite coating is a thermal spraying aluminum or aluminium alloy coating and the outer coating is a pure polyester thermosetting powder coating. The utility model has the advantages that the terminal spraying aluminum or aluminium alloy coating has a good corrosion prevention protection capability and the polyester coating has an excellent mechanical property and aging resistance property. The utility model has a good application prospect and economic benefit.
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 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 obvious assurance; 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.And low, ageing-resistant poor, the corrosive medium of external coating hardness easily permeates.
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 heat, overcomes the shortcoming of existing galvanizing or galvanizing of galvanizing plastic-blasting or galvanizing sprayed plastic coat.And this composite coating resistance to corrosion is strong, has solved low, ageing-resistant poor, the easy problem of permeating of corrosive medium of existing external coating hardness.
Aluminium is the very strong metal of a kind of activity, is easy to combine with oxygen, generates one deck densification, hard oxide protective layer, effectively prevents the further oxidation of aluminized coating.Hot-dip aluminizing technology is used for the anti-corrosion protection of steel component and obtains certain effect; but exist and zinc-plated same severe contamination problem in the aluminum plating process; the freeway guardrail of hot-dip aluminizing or hot-dip aluminizing plastic-blasting was tried out in some areas or highway section; but using wider then is hot aluminium-plated technology; the cathodic protection effect of aluminium generally is not as good as the high effect of zinc performance area; and aluminium becomes the stronger state of activation of elecrtonegativity in spraying process, can better play the cathodic protection effect to steel substrate.It is low to add the aluminium price, and its construction cost is low, and aluminium-plated technology has also been occupied certain market, is accompanied by especially comprehensively developing rapidly of hot spraying equipment of plasma spray technology, and constantly expansion is used in the heat spray of aluminium and aluminium alloys
The utility model is the problem that solves by the following technical programs: the freeway guardrail of the aluminium-plated polyester composite coating of a kind of heat, comprise guardrail board, column, cap and connector, it is characterized in that: at the substrate surface of guardrail board, column, cap and connector is composite coating with its two coating structures in fluid-tight engagement ground, and the internal layer of described composite coating is the aluminium-plated or aluminium alloy layer of heat, outerly is pure polyester thermosetting powder coating layer.
Above-mentioned hot sprayed-on Al layer spraying is with using aluminium wire, the thermal spraying aluminum alloy uses is aluminium with the alloy silk of other metals (for example zinc etc.) or uses aluminium wire and the while hot spraying of other wires, the spraying equipment that uses is arc pistol, flame gun, plasma spray gun or the quick-fried automatic doubler surface glouer that existing market is sold, and the thickness of aluminum or aluminum alloy sprayed coating is 20-80 μ m.
At least the material that contains following a kind of character in the pure polyester thermosetting powder coating of above-mentioned external coating: ultra-violet absorber, antioxidant, polytetrafluoroethylene (PTFE), glass fiber, sheet color stuffing, nano material, the thickness of pure polyester thermosetting powder coating layer are 40-120 μ m.
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 beneficial effects of the utility model are, the aluminium-plated or aluminium alloy layer of heat has good anti-corrosion protection ability, and polyester coating layer has excellent physical and mechanical performance and weather-proof ageing resistace, the utlity model has good prospects for application and economic benefit.
Description of drawings
Accompanying drawing is the structural representation of the utility model composite coating.
Among the figure: 1, guardrail steel substrate, 2, the hot spraying aluminium lamination, 3, 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 arc pistol heat aluminium-plated, form hot spraying aluminium lamination 2, thickness 30-50 μ m, workpiece is reached the standard grade and is carried out powder coating and their application then, spraying contains the pure polyester thermosetting powder coating of 0.6% ultra-violet absorber and 0.4% antioxidant, 200-220 ℃ solidifies 15min, forms pure polyester thermosetting powder coating coating 3, thickness 70-100 μ m.
After testing, face coat hardness surpasses H, and salt spray test 1000h 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.
