Abstract
The invention discloses a road guardrail and belongs to the field of road guardrails. The guardrail is coated with a composite coating layer, and the composite coating layer sequentially comprises a hot galvanizing layer, an organic zinc epoxy powder coating layer and a polyester color powder coating layer from inside to outside. By coating the polyester color powder coating layer outside the hot galvanizing layer and the organic zinc epoxy powder coating layer, corrosion caused by ultraviolet to the guardrail can be effectively prevented, the service life of the guardrail is prolonged, the polyester color powder coating layer can improve the anti-dirt capability of the guardrail, the dust falling down to the surface of the guardrail is enabled to be automatically caked, and the dust can quickly fall down from the guardrail under the washing of rainwater.
Description
Technical field
The present invention relates to a kind of guard rail, be especially a kind of road guard-rail, belong to road guard-rail field.
Background technology
It is known that " wanting getting rich first first to repair the roads ", in recent decades national road, road construction develop rapidly, meanwhile, the processing technology of road guard-rail also develops therewith.But, we also must recognize, while national development, the severe of environment is also inevitable." haze " is the topic of the complexion changed of current what is said or talked about, while harm human body is healthy, it also it is first order issue for urban construction, the particulate matters such as dust in the air caused by haze and motor-vehicle tail-gas, sulphuric acid, nitric acid are under accumulation for a long time, being formed a thick layer of on the guard rail of road, this is also that strategic point is to be solved for the problem that urban health, environmental construction cause.Design owing to the length of guard rail is accompanied by the length of road, dust on cleaning guard rail must be a troublesome large-engineering, therefore, having anti-dirty performance at road guard-rail surface spraying or make dust have the surface coating from the ability of knot, municipal administration environmental construction is necessary by this.
Summary of the invention
The problem to be solved in the present invention is to provide the road guard-rail of a kind of coloured coating, it is comprehensive that this road guard-rail belongs to that iron and steel combines a little with chemical industry, change guard rail and there is permanent anti-dirty ability, under rainwash, the dust on guardrail surface is from knot, solving a difficult problem for cleaning guard rail, simultaneously coloured coating makes guard rail be no longer traditional monochrome, has beautified city look and feel.
The present invention provides the road guard-rail of a kind of coloured coating, the surface-coated composite coating of described guard rail, and described composite coating is followed successively by hot dip galvanizing coating, organic zinc FBE and polyester color powder coating from inside to outside.
As improvement, described polyester color powder coating is the color powder coating that hydroxy polyester resin is made, and hydroxy polyester resin has good weatherability, to ensure that guardrail is adapted to different environment.
As improvement, the thickness of the spraying of described polyester color powder coating is between 60-90 μm.
As improvement, described organic zinc FBE is made up of than component following quality:
Epoxy resin 48%
Containing carboxyl polyester resin 47%
Imidazoles 2%
Firming agent 3%.
The beneficial effects of the present invention is: (1) is coated with polyester color powder coating outside hot dip galvanizing coating and organic zinc FBE, the ultraviolet erosion to guardrail can be effectively prevented, while extending its service life, polyester color powder coating can improve the anti-dirty ability of guardrail, and the dust dropping on guardrail surface is lumpd automatically, under rainwash, dust can promptly come off from guardrail；(2), hot dip galvanizing coating can play electrochemical protective effect, it is possible to prevents getting rusty of guardrail matrix；Organic FBE is strong with the bonding force of metal, have good anticorrosive property and impact strength, long service life, and cost is low compared to polyurethane cost；Its with polyester color powder coating in polar group.
Accompanying drawing explanation
Fig. 1 is road guard-rail structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As indicated with 1, the road guard-rail of the present invention, including many vertical beams 1, crossbeam 2 and column 3, it is connected with each other between many vertical beams 1 and crossbeam 2, the two ends of crossbeam 2 are fixing with column 3 respectively to be connected, and forms guardrail structure.Column 3 is fixed on ground 4.The surface of vertical beam 1, crossbeam 2 and column 3 is coated with hot dip galvanizing coating, FBE, polyester color powder coating from inside to outside successively.
Embodiment 1
First, steel component, through hot dip galvanizing process, is placed in melted zinc liquid and obtains layer protective layer by the steel of vertical beam, crossbeam and column, and the thickness of galvanizing is at 35 μm-200 μm；Except the technique of galvanizing, it would however also be possible to employ other and chemical method, as passed through Fe2O3/Mn3(PO4)2Type pretreatment fluid carries out Chemical Pretreatment, forms unformed conversion film at steel surface.
Secondly, the surface of galvanizing steel is coated with organic zinc FBE, then under 120 DEG C of environment, solidify 15min.Organic zinc FBE by the epoxy resin that mass ratio is 48%, 47% containing carboxyl polyester resin, coordinate the imidazoles of 2% and the firming agent composition of 3%.
Finally, in guardrail surface spraying polyester color powder coating, it adopts hydroxy polyester resin to make, owing to polyester belt polarized group can form good contacting with organic FBE, it is ensured that the stability of polyester color powder coating.Polyester color powder coating spraying thickness is generally between 60-90 μm.
Embodiment 2
Other technique is identical with embodiment 1, is different in that, by changing condition of cure therein.When solidification temperature is 200 DEG C, hardening time is 15min, can obtain sub-light or unglazed glossy surface.
Embodiment 3
Other technique is identical with embodiment 1, is different in that, by changing condition of cure therein.When solidification temperature is 180 DEG C, hardening time is 15min, can obtain the glossy surface of high light or zero diopter.
Above technical scheme provided by the present invention being described in detail, principles of the invention and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method and the core concept thereof of the present invention；Simultaneously for one of ordinary skill in the art, according to the thought of the present invention, all will change in specific embodiments and applications, in sum, this specification content should not be construed as limitation of the present invention.
