Abstract
The utility model discloses a metal guardrail on the expressway enhancing the system of zinc-chromate coating, wherein on the substrate of the guardrail basically coats successively with a zinc based phosphating layer, a zinc-chromate coating layer and a functional thermosetting powder coating layer, and on the coffin corner of the substrate of the guardrail coats successively with a zinc based phosphating layer, a metal coating layer, a zinc-chromate coating layer and a functional thermosetting powder coating layer on the outermost layer. The guardrail of the utility model markedly enhances the weatherability, corrosion resistance and scratch resistance. Particularly strengthening the collision and corrosion resistance prolongs the service life of the guardrail.
Description
Technical field
The present invention relates to a kind of expressway safety facility, be specifically related to a kind of freeway guardrail that strengthens the zinc-base composite coating system that has.
Background technology
Flourish along with China's freeway traffic cause; the application study of safety device such as guardrail is more and more deep; requirement to its anti-corrosion protection improves constantly; the coating protection technology is sprayed paint plastic-blasting to zinc-plated (aluminium) plastic-blasting up till now galvanizing (aluminium) plastic-blasting again that sprays paint from the blackboard at initial stage; the antiseptic power of guardrail coating has had remarkable enhancing; but owing to producing a large amount of waste water,waste gas and industrial residue serious environment pollutions in various zinc-plated (aluminium), galvanizing (aluminium) activities; harm people life is restricted the popularization of this guardrail.In addition, find that the corrosion problem very easily appears in its corner of guardrail of zinc-base coating in outdoor for many years practical application experiment, tracing it to its cause one is that the corner coating is thin, and corrosive medium immerses easily; The 2nd, the corner is vulnerable to collide with and causes coating damage even come off, and makes base material lose protection.
Summary of the invention
Purpose of the present invention just provides a kind of freeway guardrail that strengthens the zinc-base composite coating system that has, to solve the environment pollution that original guardrail produces in process of production, overcome simultaneously that existing coat system external coating hardness is low, the easy problem of infiltration of loss of properties on aging, corrosive medium; The damaged position, corner to being subject to collide, specialized designs a kind of metal coating, increase anti-corrosion function, more improved impact resistance.
The purpose of this utility model is achieved through the following technical solutions: a kind of freeway guardrail with enhancing zinc-base composite coating system is characterized in that: apply Zinc phosphating layer, zinc-base powdery paints layer and functional thermosetting powder coating layer successively on the guardrail base material; Applying Zinc phosphating layer, metal coating, zinc-base powdery paints layer, outermost layer successively in guardrail base material side angle part is functional powder thermosetting coating.
Guardrail described in the utility model comprises guardrail board, column, non-coring, cap, nut and other ancillary facilities.
The beneficial effects of the utility model are, have strengthened anti-collision, the resistance to corrosion of guardrail corner, have significantly improved weather-proof, the decay resistance of whole guardrail, ability is bumped in anti-wiping.The environment pollution of having avoided original guardrail to produce in process of production.

The coating operating procedure is as follows:
As shown in Figure 1, after guardrail hardware matrix 1 surface being carried out the degreasing and rust removal processing, carrying out Zinc phosphating handles, form Zinc phosphating layer 2, spray the epoxy zinc-rich powdery paints then, spray glass-fiber reinforced thermosetting polyester powdery paints behind the semi-solid preparation again, fully solidify the back and form zinc-base powdery paints coating 4, functional thermosetting powder coating layer 5.
As shown in Figure 2, after guardrail hardware base material 1 surface being carried out the degreasing and rust removal processing, carrying out Zinc phosphating handles, form Zinc phosphating layer 2, spray zinc in opposite side angular position forms metal coating 3 then, spray the zinc-base powdery paints again, spray glass-fiber reinforced thermosetting polyester powdery paints behind the semi-solid preparation again, fully solidify the back and form zinc-base powdery paints coating 4, functional thermosetting powder coating layer 5.
As shown in Figure 3, after polishing is carried out on guardrail hardware base material 1 surface, the aluminium-plated formation metal coating 3 in opposite side angular position, carrying out Zinc phosphating then handles, form Zinc phosphating layer 2, spray epoxy resin and zinc-enriched heavy anti-corrosive again, spray again behind the semi-solid preparation and add nanometer SiO
2The thermosetting polyester powdery paints, fully solidify the back and form zinc-base powdery paints coating 4, functional thermosetting powder coating layer 5.
After testing, the outermost layer coating has the hardness of film height, the characteristics that anti-collision is strong.Face coat hardness surpasses 2H, and salt spray test is corner non-corroding phenomenon after 1000 hours, corner impact failure rate decline 70-90% in the actual application, and breaking point resistant to rust ability was above 90 days.
