Problems solved by technology

[0002] With the continuous demand of the door and window market, the traditional white profile can no longer meet the needs of human decoration. Many profile manufacturers use various technologies to change the surface color of the profile. Outdoors, so very high requirements are placed on the weather resistance of the film. The weather resistance of ordinary PVC films and composite films is not enough to withstand natural climate changes such as wind, sun, rain, etc. for a long time, resulting in Rapid aging, chalking and shedding in just a few years
Although there are currently several German PVC+PMMA composite films in the world that do better in weather resistance, it is difficult to open up sales in the Chinese market due to their high prices.

Embodiment 1

[0029] A film-coated spray-coated profile, the surface of the glass fiber reinforced polyurethane profile body is covered with a layer of PVC+PMMA composite film layer, and the outer surface of the film layer is sprayed with a layer of polyurethane paint.

[0030] The process of film coating spraying on profiles is as follows:

[0031] (1) Prepare glass fiber reinforced polyurethane profiles;

[0032] (2) Select PVC+PMMA composite film according to needs;

[0033] (3) Apply a layer of PUR special glue on the surface where the PVC+PMMA composite film layer is in contact with the glass fiber reinforced polyurethane profile;

[0034] (4) Use a laminating machine to cover the film, and the thickness of the film is 0.18mm;

[0035] (5) Spray the polyurethane coating on the outer surface of the PVC+PMMA composite film of the glass fiber reinforced polyurethane profile.

Embodiment 2

[0037] A film-coated spray-coated profile, the surface of the glass fiber reinforced polyurethane profile body is covered with a layer of PVC+PET composite film, and the outer surface of the film layer is sprayed with a layer of polyurethane paint.

[0038] The process of film coating spraying on profiles is as follows:

[0039] (1) Prepare glass fiber reinforced polyurethane profiles;

[0040] (2) Choose PVC + PET composite film according to the needs;

[0041] (3) Apply a layer of PUR special glue on the surface where the PVC + PET composite film layer is in contact with the glass fiber reinforced polyurethane profile;

[0042] (4) Use a laminating machine to cover the film, and the thickness of the film is 0.22mm;

[0043] (5) Spray the polyurethane coating on the outer surface of the PVC + PET composite film of the glass fiber reinforced polyurethane profile.

Embodiment 3

[0045] A film-coated spray profile, the surface of the glass fiber reinforced polyurethane profile body is covered with a layer of TPO film, and the outer surface of the film layer is sprayed with a layer of polyurethane paint.

[0046] The process of film coating spraying on profiles is as follows:

[0047] (1) Prepare glass fiber reinforced polyurethane profiles;

[0048] (2) Choose TPO film according to your needs;

[0049] (3) Apply a layer of PUR special glue on the surface where the TPO film layer is in contact with the glass fiber reinforced polyurethane profile;

[0050] (4) Use a laminating machine to cover the film, and the thickness of the film is 0.20mm;

[0051] (5) Spray the polyurethane coating on the outer surface of the TPO film of the glass fiber reinforced polyurethane profile.

Abstract

The invention discloses a laminating spraying section bar. The laminating spraying section bar mainly comprises a glass fiber reinforced polyurethane section bar body or a glass fiber reinforced plastic section bar body, a film layer covering the outer surface and / or the inner surface of the section bar body, and a coating layer sprayed on the outer surface of the film layer. The invention also discloses a laminating spraying method used for production of the laminating spraying section bar. According to the laminating spraying method, defects of the section bar body can be avoided, the surface of the section bar can be decorated, cost is reduced, weather resistance is increased, colorization is realized, and strength and flatness of the surface of the section bar are ensured at the same time.

Description

technical field [0001] The invention relates to a film-coated profile, in particular to a film-coated profile with a coating and a film-coating spraying process for the profile. Background technique [0002] With the continuous demand of the door and window market, the traditional white profile can no longer meet the needs of human decoration. Many profile manufacturers use various technologies to change the surface color of the profile. Outdoors, so very high requirements are placed on the weather resistance of the film. The weather resistance of ordinary PVC films and composite films is not enough to withstand natural climate changes such as wind, sun, rain, etc. for a long time, resulting in Rapidly ages, chalks and sheds in just a few years. Although there are currently several German PVC+PMMA composite films in the world that do better in weather resistance, it is difficult to open up sales in the Chinese market due to their high prices. Therefore, an economical and p...
