The aluminum profile surface treatment technology mainly comprises the following steps: powder spraying, fluorocarbon spraying, electrophoresis, anodic oxidation and wood grain transfer printing treatment.
The fluorine resin has a fluorine-carbon bond structure with shorter bond length and bond energy far higher than that of carbon-carbon and carbon-oxygen bonds, and can be closely arranged around the polymer, so that the fluorocarbon powder coating shows excellent weather resistance and is widely used as a protective decorative coating of aluminum profiles.
The fluorocarbon spraying process comprises the following steps: surface pretreatment-primer-topcoat- (varnish) -curing and baking. Patent application number CN202110580004.1 discloses a preparation method of a heat-insulating aluminum alloy section bar, which comprises the following steps: performing sand blasting treatment on the glue injection notch of the aluminum alloy substrate, and forming a sand surface on the surface of the glue injection notch; passivating and pre-treating the aluminum alloy substrate; the aluminum alloy base material is subjected to primer spraying treatment by PVDF fluorocarbon coating, and is dried; the aluminum alloy base material is sprayed with PVDF fluorocarbon paint and dried; solidifying the aluminum alloy base material; embossing a glue injection notch of an aluminum alloy substrate, and forming a concave tooth opening at the edge of the glue injection notch; injecting heat insulation glue into the glue injection notch, and drying and curing; and cutting the bridge of the aluminum alloy base material after glue injection to obtain a finished product. The preparation method can obtain the aluminum alloy section bar with good weather resistance and heat insulation effect, not only meets the performance requirements of longitudinal shearing resistance and the like, but also is suitable for the outdoor irradiation of high-strength sunlight. Patent application number CN201510029035.2 discloses an aluminum alloy profile and a manufacturing method thereof, comprising: the method comprises the following steps of (1) preprocessing an aluminum alloy profile base material; (2) Performing anodic oxidation treatment on the pretreated aluminum alloy section to form an oxide film on the surface of the aluminum alloy section; (3) Carrying out anode electrophoresis treatment on the aluminum alloy profile to form an electrophoresis paint film on the surface of the aluminum alloy profile; (4) curing and baking the aluminum alloy profile; (5) And spraying fluorocarbon paint on the surface of the aluminum alloy profile to form a fluorocarbon coating. The fluorocarbon coating at least comprises a fluorocarbon primer layer and a fluorocarbon top layer, and also comprises a fluorocarbon clear coat layer and a fluorocarbon middle coating. The production process of the manufacturing method is stable and easy to implement. The surface of the produced aluminum alloy section product has special composite film protective coating, has excellent corrosion resistance, weather resistance and other performances, can effectively resist ultraviolet rays, high humidity and corrosion damage of aggressive salt ions to the aluminum alloy section, and is particularly suitable for sea island and sea area buildings under marine climate.
However, the existing PVDF fluorocarbon coating has poor glossiness and gloss retention, and is difficult to produce a fluorocarbon paint film with high glossiness. The primer sprayed on the surface of the aluminum profile can enhance the protection of the base material, improve the adhesive force of the finish paint and ensure the color uniformity of the finish paint film. The finish paint can provide the required decorative color, so that the appearance meets the design requirement, and the surface of the aluminum profile is protected from being corroded by the external environment. The varnish has the function of protecting the finish paint coating, increasing the metallic luster of the color of the finish paint, and having more vivid appearance and bright luster. However, the adhesive force between the paint films of all layers and the adhesive force between the paint film and the aluminum profile are poor under the existing technological conditions, so that the paint film is easy to fall off and the due effect of the paint film cannot be exerted. In addition, the quality of the aluminum profile product sprayed by fluorocarbon is unstable, the color is uneven, and the color difference problem exists.

the lamellar interlayer structure of the talcum powder can effectively improve the leveling property of the paint, fill gaps among aluminum powder, reduce the defects of the coating and improve the gloss retention of the coating; but also can prolong the diffusion path of corrosive medium, thereby improving the weather resistance of the coating film. Talc having a high aspect ratio also imparts higher impact resistance and fracture toughness to the coating film when the coating film is cured. Therefore, talcum powder in the additive is added into fluorocarbon finish paint, so that excellent gloss retention and leveling property can be provided for the coating film, and the impact resistance and weather resistance of the coating film can be improved.
The molecular structure of the perfluoro octyl triethoxy silane as the silane coupling agent contains a large number of fluorine-containing groups, and the silicon dioxide is modified by perfluoro octyl triethoxy silane, so that the particle surface of the silicon dioxide is provided with hydrophobic groups, thereby endowing the surface with superhydrophobicity. When the powder coating is cured at high temperature, white spots are easy to appear on the surface of the powder coating due to water absorption of the coating. The ethoxy in the perfluorooctyl triethoxy silane molecular structure and the active silicon hydroxyl on the surface of the silicon dioxide are subjected to coupling reaction, so that the silicon dioxide can be promoted to be dispersed in an organic system. However, it was found in the course of the study that the modified silica obtained by using perfluorooctyl triethoxysilane alone has poor compatibility with organic systems. In order to solve the problems, the invention adopts the following method: firstly, under the catalysis of triphenylphosphine, benzoic acid and perfluorooctyl triethoxysilane undergo esterification reaction to generate an ester compound; secondly, the ester compound and the fluorosilane modified silicon dioxide undergo a coupling reaction, and the functional group of the ester compound is grafted on the surface of the silicon dioxide (namely an intermediate product is formed), so that the compatibility and the dispersibility of the silicon dioxide in an organic system are improved; finally, the perfluoro octyl triethoxy silane is utilized to carry out coupling reaction with active silicon hydroxyl on the surface of the intermediate product, so that the functional group of the ester compound is firmly coated and fixed on the surface of the silicon dioxide, the silicon dioxide is not easy to fall off, and the compatible dispersion effect of the silicon dioxide in an organic system is affected.
The aluminum powder can be orderly arranged in the film forming process, and the gloss, texture and color uniformity of the coating film are directly affected. The low-density polyethylene in the additive has high shrinkage, and can enable a paint film to shrink rapidly in the curing process of curing, prevent aluminum powder from moving up and down in the paint film and assist the aluminum powder to be arranged horizontally and directionally. The aluminum powder has high specific gravity and is easy to sink, and the silicon dioxide in the additive can have good anti-sinking effect. The existing fluorocarbon powder coating only has excellent weather resistance, and the silver ion antibacterial agent is added to endow the paint film with antibacterial property to inhibit the breeding of microorganisms on the surface of the aluminum profile. The chlorinated polyethylene contains chlorine atoms with strong polarity, and the chlorine atoms are added into the fluorocarbon finish paint to use the strong polarity, so that the bonding force between the chlorinated polyethylene and the fluorocarbon primer and the fluorocarbon varnish can be enhanced. The compactness of the paint film can be improved by adding glutaric anhydride.
Furthermore, the film forming substance adopted by the fluorocarbon primer comprises hydroxy acrylic resin and polyester resin besides PVDF fluorocarbon resin, and the combination of the above components is matched with each other, so that the fluorocarbon primer can be firmly attached to the surface of the passivation film, and the adhesive force of a fluorocarbon paint film and an aluminum profile is improved. In addition, hydroxyl functional groups of the hydroxyl acrylic resin in the fluorocarbon primer can be subjected to crosslinking reaction with glutaric anhydride in the fluorocarbon finish paint, so that the bonding strength between the fluorocarbon primer and the fluorocarbon finish paint is improved.
