Description
Technical field
The utility model is related to a kind of safety device for travelling driving vehicle deceleration, deflecting or stopping, more specifically,
It is related to a kind of plastic-spraying guardrail board.
Background technology
Freeway guardrail is a kind of continuous structure for mutually being spliced with corrugated steel guard rail plate and being supported by principal post, vehicle
When colliding it, because waveform steel guard rail plate plays the role of good Impact Resisting Capability and energy absorption, it is neither easy to be smashed, together
When vehicle and driver and conductor can be played a very good protection again.
The guardrail of highway edge both sides is built up in the prior art due to being month after month in wind, Exposure to Sunlight, sleet throughout the year
In the adverse circumstances drenched, easily corrosion is damaged, and has severely impacted its service life.Easily given birth to solve guardrail mentioned above
The problem of rust, typically can be using the guardrail board for carrying out galvanizing treatment or galvanized plastic-sprayed treatment, however, it was found that guardrail board can still give birth to
Rust, and the highway corrugated guardrail plate after application is found, the corrosion at its initial stage is essentially all to be opened from the corner of waveform beam slab
If simultaneously gradually going deep into and spreading what is come, wave beams part corrosion cracking is ultimately caused, serious blocking for corrugated guardrail plate of reduction is hit
Protective action.And found main reasons is that being influenceed by corner face shaping, the corner of original waveform beam slab through investigation and analysis
Be right angle, sheet material it is zinc-plated or spraying when its corner coating it is relatively thin, corrosive medium readily penetrate through coating reach base material, it is right
Steel substrate surface forms corrosion.It is existing for this situation, what is had with the addition of the auxiliary agents such as thixotropic agent to increase side in coating
The thickness of angle coating, but the perishable situation in waveform beam slab corner does not have basic change always.
In addition it has also been found that highway corrugated guardrail plate is aoxidized and aging, lustrous surface under condition of work, easily in the wild
Subtract light, reduce warning and the guiding function of guardrail so that the service life of guardrail board is substantially reduced.
The content of the invention
1. the utility model technical problem to be solved
The purpose of this utility model is the easy oxidation that overcomes existing guardrail board to exist and aging, and easy-to-rust is not
A kind of foot, there is provided plastic-spraying guardrail board.Using the technical solution of the utility model, the corner of inner metallic layer is arc chord angle, its appearance
Face is coated with prime coat, and the outer surface of prime coat is coated with poly chloroacetic acid powder coating, drastically increases the antirust of guardrail board
Performance；The outer surface of poly chloroacetic acid powder coating is also coated with UV coatings, improves the inoxidizability of guardrail board, extends guardrail
The service life of plate.
2. technical scheme
To reach above-mentioned purpose, the technical scheme that the utility model is provided is：
A kind of plastic-spraying guardrail board of the present utility model, including inner metallic layer, the outer surface of described inner metallic layer is coated with
