Description
Technical Field
The invention belongs to the field of coating films for highway guardrails, and particularly relates to a highway guardrail marking coating film and a preparation method thereof.
Background
Guardrails are usually arranged on the two sides and the middle boundary of the highway as safety protection and protection facilities. In order to increase the warning protection of the road barrier for road users, in particular drivers, a reflective paint film, such as the most commonly used yellow reflective paint film, is usually applied to certain areas of the road barrier.
However, in the use environment of the highway guardrail, a large amount of dust, automobile exhaust, volatile organic compounds in the automobile exhaust and the like exist, and the dust, the automobile exhaust, the volatile organic compounds in the automobile exhaust and the volatile organic compounds can be continuously attached to and accumulated on the highway guardrail, so that on one hand, the pollutants can corrode the highway guardrail and a coating film on the surface of the highway guardrail, and the service life of the highway guardrail is influenced; on the other hand, the pollutants can also influence the marking effect of the marking paint film, and increase the potential safety hazard.
Therefore, the marking paint film for the highway guardrail needs to have a lasting anti-corrosion effect and high-efficiency self-cleaning performance on the highway guardrail.
Self-cleaning surfaces have received extensive attention and research today. Based on the difference of self-cleaning principle, the self-cleaning device can be divided into a super-hydrophobic self-cleaning surface and a photocatalytic self-cleaning surface. The super-hydrophobic self-cleaning surface utilizes the free rolling of water drops on the super-hydrophobic surface to take away dust on the surface, thereby realizing the self-cleaning effect. However, in practical applications, on one hand, due to the complex components in the dust and the existence of hydrophobic pollutants, water drops can not be effectively removed by the free rolling of the water drops on the super-hydrophobic surface, and along with the enrichment of the pollutants on the super-hydrophobic surface, the super-hydrophobic characteristic of the super-hydrophobic surface is gradually lost, and the self-cleaning effect is increasingly poor; on the other hand, since the rolling of water drops on the super-hydrophobic surface has arbitrariness, the self-cleaning effect on the whole surface cannot be guaranteed to be completely clean, and the self-cleaning effect of the surface is increasingly poor along with the increase of the area which is not self-cleaned.
Accordingly, there is a need to provide a long lasting and effective coating film for highway barriers.
Disclosure of Invention
The inventor of the present invention has improved the existing paint film for highway guardrail marking due to the above-mentioned disadvantages. The existing coating film for highway guardrail identification is usually a self-cleaning coating film with a super-hydrophobic surface, and the rolling of water drops on the common super-hydrophobic self-cleaning surface has arbitrariness and randomness, so that the self-cleaning effect is insufficient. Furthermore, as hydrophobic contaminants are deposited on the superhydrophobic surface, water droplets roll around the hydrophobic contaminants, so that more and more areas of the superhydrophobic surface exist where no water droplets roll through for self-cleaning. The inventors of the present invention have made improvements to this problem.
The utility model provides a highway guardrail sign coating film, includes guardrail basement, super hydrophilic coating rete, colored super hydrophobic coating rete in proper order, its characterized in that: the colored super-hydrophobic coating film layer is provided with a plurality of super-hydrophilic tracks.
The super-hydrophilic coating film layer comprises the following components: 30-60 parts of hydrophilic resin, 10-20 parts of nano titanium dioxide, 0.1-0.5 part of flatting agent, 10-20 parts of hydrophilic nano aluminum oxide and 1-5 parts of wetting agent.
The colored super-hydrophobic coating film layer comprises the following components: 40-60 parts of acrylic resin, 20-30 parts of fluorocarbon resin, 10-20 parts of hydrophobic nano silicon dioxide, 10-30 parts of coloring pigment, 0.1-0.5 part of flatting agent and 1-5 parts of wetting agent.
According to the invention, the super-hydrophilic tracks arranged on the colored super-hydrophobic coating film layer are utilized to realize the directional rolling of water drops on the surface of the colored super-hydrophobic coating film layer, so that the high-efficiency self-cleaning of the surface of the identification coating film is realized, and the stability and the effectiveness of the identification effect are ensured. The cross section shape, size, path, distribution density and the like of the super hydrophilic rail can be set randomly according to needs, so that the water drops can be ensured to directionally roll in most of the whole colored super hydrophobic surface, and self-cleaning is completed. For example, the cross-sectional shape of the super hydrophilic rail may be V-shaped, U-shaped, inverted delta-shaped. The width of the super-hydrophilic track is 50-1000um, preferably 50-200um, more preferably 50-100 um. The depth of the super-hydrophilic track is approximately equal to the thickness of the colored super-hydrophobic coating film layer, and the corresponding area of the colored super-hydrophobic coating film layer is damaged, so that the super-hydrophilic coating film layer below the exposed part is exposed, and the super-hydrophilic track is formed. The destroying method includes laser processing, mechanical processing and the like. The path of the super-hydrophilic tracks can be linear, S-shaped or zigzag, and each super-hydrophilic track is parallel to each other. The S-shaped or broken line type is preferred, the impact of water drops on the rail when the water drops roll on the super-hydrophilic rail is increased by utilizing the bending of the super-hydrophilic rail, the cleaning effect of the water drops on impurities such as dust is enhanced, and the self-cleaning effect of the water drops is increased. In order to ensure that the water drops roll on most areas of the whole colored super-hydrophobic surface, the distribution density of the super-hydrophilic tracks is higher, but the interval between two adjacent super-hydrophilic tracks is 100-1000um in consideration of the manufacturing operability and the visibility of the marking effect.
In the present invention, the driving force for rolling the water droplets is derived from gravity, and therefore, the direction of the super-hydrophilic orbit is substantially from the top to the bottom.
A preparation method of a coating film for a highway guardrail mark comprises the following steps:
(1) cleaning and pretreating the surface of the stainless steel highway guardrail;
(2) preparing a corresponding super-hydrophilic coating according to the composition of the super-hydrophilic coating film layer, then coating the super-hydrophilic coating on the surface of the highway guardrail, drying and curing to obtain a super-hydrophilic surface;

(4) the tracks are formed on the colored superhydrophobic surface by laser processing or mechanical processing, i.e., superhydrophilic tracks.
The invention has the beneficial effects that:
1. the super-hydrophilic and colored super-hydrophobic film layers are simultaneously constructed on the surface of the guardrail, so that the guardrail can be effectively protected against corrosion.
2. The super-hydrophilic rail is formed on the colored super-hydrophobic surface, and the cross-sectional shape, size, path, distribution density and the like of the super-hydrophilic rail are controlled, so that the water drops are ensured to directionally roll on most areas of the whole colored super-hydrophobic surface, effective self-cleaning is realized, and the lasting effectiveness of the guardrail mark is ensured.
