Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a double-coating protection system powder coating for a highway guardrail.
Background
The highway guardrail is an important facility for maintaining the order of the highway and guaranteeing the driving safety, and has the first function of preventing the casualties caused by the accident rush of the automobile out of the highway; the second function is to guide the vehicle in the opening direction.
To enhance the guiding function of the guardrail, paint is often applied to the surface of the guardrail. The paint is required to have high reflectivity, weather resistance and obvious color.
The high reflectivity is used for reflecting the light of the vehicle lamp to remind a driver of the position of the road surface under the condition of insufficient illumination.
The weather resistance is to ensure that the coating still can play a role after long-term use.
Color conspicuity means that the coating typically needs to be sufficiently contrasting with its own color in an outdoor environment to prevent it from melting into the background; high saturation colors, which are relatively rare in nature, such as orange, white, pink, etc., are often used.
Disclosure of Invention
The invention aims to provide a double-coating protection system powder coating for a highway guardrail.
The technical scheme adopted by the invention for solving the technical problem is as follows:
a double-coating protection system powder coating for a highway guardrail comprises a first coating and a second coating;
the first coating comprises the following components in percentage by weight:
the second coating comprises the following components in percentage by weight:
acrylic resin 30-60
40-70 parts of glass beads;
the second coating is coated on the surface of the first coating; the first coating is coated on the surface of the substrate.
Preferably, the metal oxide particles comprise at least one of titania, alumina, zirconia, and zinc oxide.
Preferably, the metal oxide particles are titanium dioxide which is rutile and/or anatase.
Preferably, the leveling agent is an organic silicon leveling agent.
Preferably, the inorganic pigment includes at least one of iron oxide yellow, transparent iron yellow, titanium yellow, iron oxide red, chromium oxide green, iron blue and cobalt blue.
Preferably, the glass beads are solid glass beads.
Preferably, the diameter of the glass beads is 30 to 200 μm.
Preferably, the diameter of the metal oxide is 15 μm or less.
The guardrail is sprayed in a double-coating mode, the first coating is directly contacted with the guardrail, the ground color is provided, and the service life is good; the second coating provides both light reflection and scattering, greatly enhancing the road-pointing effect at low light levels.
The acrylic resin used in the present invention is a water-soluble thermoplastic acrylic resin, and is a main component of the coating material of the present invention. The metal oxide particles are used to provide sufficient covering power and to adjust the brightness of the inorganic colorant, and have a certain resistance to weathering. Although the inorganic pigment is not much in color richness, the use scene of the invention has low requirements on the richness of the color, and more requirements on color firmness and durability are higher; in this case, the inorganic coloring material has outstanding advantages of fastness in color, high durability and unsuitability for reaction with other components. Ultraviolet light absorbers and leveling agents are used to increase the weatherability of the coating. Deionized water is used to adjust the viscosity of the coating. The glass beads are used for increasing the light reflecting and scattering capacity of the coating, so that the driving of the vehicle can still be correctly guided in a dark environment.
Detailed Description
The following specific examples are provided to further illustrate the present invention so that those skilled in the art may better understand the invention and practice it, but the examples are not intended to limit the invention.
Highway barriers are in most cases made of metal, but in a few cases also cement-based. However, the surface of the guardrail is uneven and rough whether metal or cement is adopted, so that the surface of the guardrail needs to be filled by the first coating attached to the guardrail; and preferably the surface of the guard rail is properly ground flat prior to application.
Then, in order to extend the useful life of the coating, ultraviolet light absorbers are used to reduce the sun's damage to the coating.
The first coating is the key point of the coating system, and plays roles in protecting the guardrail, providing ground color and smoothing the surface of the guardrail.
In order to protect the first coating and to enhance the light reflecting and scattering capabilities of the coating, a second coating is provided. Therefore, the second coating layer must be transparent or otherwise obscure the undertone of the first coating layer.
In the invention:
the leveling agent is basf BYK-355 or BYK-3455; the ultraviolet light absorber is either a basf Tinuvin 5151 or Tinuvin 292; yellow iron oxide, transparent yellow iron oxide are produced by BAYFERROX company, yellow titanium is basf K2001FG, and red iron oxide is BAYFERROX 4130; chromium oxide green is produced by Bohai sea chemical group in Tianjin city, iron blue is produced by Zhejiang Yonghua chemical company, and cobalt blue is produced by Hunan Jufa scientific and technological company; the titanium dioxide is basf (basf) PA 6; the alumina is defluorination alumina of Shanghai Liangjiang titanium white chemical products, Inc.; zirconium oxide is produced by Yino chemical technology, Inc. of Guangzhou city; zinc oxide is produced by basf; the acrylic resin is Japanese mitsubishi BR-113 water-based acrylic resin; the glass beads are produced by Oncorhynchus Korea company, Tianjin City, Port, Germany and trade Co.
The manufacturing method of the invention is as follows:
a first coating layer:
heating the acrylic resin to a viscous state according to the measurement, wherein the acrylic resin shows the mechanical characteristics of the fluid; adding the metal oxide particles and the inorganic pigment at least 600rpm under the condition of keeping the temperature, and then adding the ultraviolet absorber and the leveling agent; finally adding deionized water and continuously rotating for a period of time; the entire mixing process remains sealed.
And (3) second coating:
before being mixed with acrylic resin, the glass beads need to be cleaned by distilled water and dried; then heating the acrylic resin to viscous state according to the measurement, adding the glass beads, uniformly mixing, and stopping after the rotation speed of 1500rpm is used for 20-60 minutes at 500rpm in the first 20 minutes after the addition.
Powder coatings were made according to the above-described manufacturing method, with the specific components listed in tables 1 and 2:
table 1: composition of the first coating
Table 2: components of the second coating
| Numbering | 1 | 2 | 3 | 4 | 5 | 6 |
