Description
Technical field
The utility model belongs to coating structure, more particularly to a kind of coating for metal surfaces structure.
Background technique
With the development and quickening of urban construction, metal ceiling, metal curtain wall are answered extensively in building decoration
With.People start to pursue nature, the decorated style with " soft " sense, by coating technology, can make metal surface with bamboo,
Wood, the texture of stone or pure color pattern, and the market demand increasingly increases.
But weak acid, weak base corrosive environment in, it is such special that traditional metal surface painting technology is unable to satisfy
Demand under weather conditions is embodied in following several points:
1, such as border on the sea, the air humidity of coastal waters project it is bigger, and seawater is in alkalinity, it is easier to produce to coating and metal material
It is raw to corrode, corruption.
2, it such as borders on the sea, coastal waters project, faces bigger wind load demand, therefore the attachment force request of substrate and coating is more
It is high.
3, such as border on the sea, the intensity of sunshine of coastal waters project and sunshine-duration are generally higher than urban environment, keep coating more easily old
Change and fade, loses original protective effect and aesthetic.
4, such as chemical plant project, traditional coating process are easy to be corroded, to accelerate aging and the rust of metal material
Erosion.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of coating for metal surfaces structures, can increase coating
Adhesive force improves the surface hardness of coating, enhances the rotproofness of coating, reduces the gloss difference and color difference of coating, extends
The protection timeliness of coating.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solutions:
A kind of coating for metal surfaces structure, including successively the antioxygen priming paint coated on metal material materials and parts surface turns from bottom to up
Change layer, the weather-proof colored paint layer of anti-corrosion, the paint of resistance to coloured light finish coat, wherein antioxygen priming paint conversion coating is fluorine carbon primer base, and anti-corrosion is weather-proof
Colored paint layer is PVDF topcoat paint, and finishing varnish is transparent polyurethane coating.
The antioxygen priming paint conversion coating with a thickness of 5~8 μm
The weather-proof colored paint layer of the anti-corrosion with a thickness of 16~20um.
In the paint of the resistance to coloured light finish coat with a thickness of 16~20um.
The metal material materials and parts are the metal plate of 0.5~2.0mm thickness.
Using a kind of coating for metal surfaces structure of the utility model, have the advantages that several:
1, uniform coating thickness, and total coating thickness deviation≤3 micron.
2, coating gloss difference is small, with ± 3 unit of batch gloss difference.
3, the color difference of coating is small, color and 2 unit of reference colour discrepancy delta E <.
4, the color difference of coating is small, with batch color difference Δ E < 0.7.
5, weather resistance is brilliant, 4000 hours 1 grade of salt mist experiments.
6, coating hardness is tested, and pencil hardness can achieve 3H.
7, metal coating can be made to meet tightened up application environment, such as bordered on the sea, the inferior gold of offshore area, corrosive environment
Belong to coating specification.
Detailed description of the invention
The utility model is described in detail with reference to the accompanying drawings and detailed description:
Fig. 1 is the schematic diagram of the coating for metal surfaces structure of the utility model.
Specific embodiment
The coating for metal surfaces structure of the utility model is as shown in Figure 1, include successively being coated on metal material from bottom to up
The weather-proof colored paint layer 3 of the antioxygen priming paint conversion coating 2 on 1 surface of part, anti-corrosion, the paint of resistance to coloured light finish coat 4, wherein
Antioxygen priming paint conversion coating 2 uses fluorine carbon priming paint, and coating thickness is 5~8um.By 45 seconds or so high-temperature bakings
Afterwards, 224~232 DEG C of baking temperature, can be in the antioxygen priming paint conversion that 1 surface of metal material materials and parts forms coating uniformly and adhesive force is strong
Layer 2.It is no paint-shedding that the adhesive force of antioxygen priming paint conversion coating 2 through above-mentioned processing can achieve 6~8 burnt impact forces, the test of 1mm frame
Reach 0 grade.
The weather-proof use of the colored paint layer 3 PVDF finishing coat of anti-corrosion (F-C paint, it is a kind of using fluororesin as the paint of main film forming substance or painting
Material), finishing coat color, 16~20um of coating thickness can be customized according to customer requirement.After 48 seconds high-temperature bakings, baking temperature
232~242 DEG C of degree can form on the surface of prime coat and coat the uniform weather-proof colored paint layer 3 of anti-corrosion.The weather-proof colored paint layer 3 of the anti-corrosion
Not chloride, fluoride or halide.
The paint of resistance to coloured light finish coat 4 uses transparent polyurethane coating, and coating thickness is 16~20um.By 48 seconds high temperature
After baking, 242~249 DEG C of baking temperature, it can be formed on the surface of top coat layer and coat the uniform paint of resistance to coloured light finish coat 4.This is resistance to
The adhesive force of coloured light paint finish coat 4 can achieve that 6~8 burnt impact forces are no paint-shedding, and the test of 1mm frame reaches 0 grade, the surface of lacquer painting
Hardness reaches 3H.
In addition, above-mentioned metal material materials and parts 1 should carry out pretreatment early period, specifically successively includes: degreasing, clean, dry up, rectify
Flat, immersion coating, chemistry baking can just carry out the spraying of priming paint after chemistry is cooling.
The aluminium sheet of 0.5mm to 2.0mm thickness can be selected in the metal plate member, is also possible to the metal plate of other materials, such as
Galvanized steel plain sheet, Al-Zn coated steel, stainless steel plate, copper sheet etc..
In conclusion the coating for metal surfaces structure of the utility model, first forms one layer of densification on 1 surface of metal material materials and parts
Antioxygen priming paint conversion coating 2, effectively to strengthen antioxygenic property；Then one layer of anti-corrosion is formed on 2 surface of antioxygen priming paint conversion coating
Weather-proof colored paint layer 3 has extremely strong anti-corrosion and weather resistance, guarantees that color and gloss are more persistently and stable；Finally in anti-corrosion
Weather-proof 3 surface of colored paint layer forms the one layer of paint of resistance to coloured light finish coat 4, assigns coating superpower corrosion-resistant and resistance to delineation performance.Using
The coating structure of the utility model can effectively improve protective effect of the coating to sheet metal, and make the color of coating for a long time
As newly.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Utility model, and being not used as the restriction to the utility model, if in the spirit of the utility model, to
