Description

Technical Field

[0001] This application relates to the field of door and window profile technology, and in particular to a novel high-performance glass fiber reinforced polyurethane door and window profile with a decorative surface. Background Technology

[0002] Fiberglass reinforced polyurethane profiles, as door and window profiles, have advantages such as being lightweight, high-strength, energy-saving, fire-resistant, dimensionally stable, and corrosion-resistant. However, the weather resistance and aging resistance of bare polyurethane profiles are relatively poor, and they are easily affected by factors such as ultraviolet rays, humidity, and temperature. After long-term exposure, they are prone to deformation, discoloration, cracking, and strength reduction. To solve this problem, surface coating processes are often used for fiberglass reinforced polyurethane profiles.

[0003] However, in terms of coating of glass fiber reinforced polyurethane profiles, industry standards are still in a relatively early stage. There are no requirements for coating types, parameters, performance levels, or outdoor service life of the coatings. As long as the coating thickness meets the requirements, it is acceptable. For this reason, the durability and weather resistance of coatings used to protect polyurethane profiles are problematic. In addition, the cost of surface coating of polyurethane profiles is relatively high due to the limitations of the process.

[0004] Therefore, we propose a new type of high-performance glass fiber reinforced polyurethane door and window profile with a decorative surface to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a new type of high-performance glass fiber reinforced polyurethane door and window profile with decorative surface, which effectively reduces production costs and improves UV resistance, preventing door and window profiles from aging due to direct UV radiation.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a novel high-performance glass fiber reinforced polyurethane door and window profile with decorative surface, comprising a glass fiber reinforced polyurethane window sash profile and a glass fiber reinforced polyurethane frame profile, wherein an aluminum alloy exterior decorative panel is fixedly connected to the outer surface of both the glass fiber reinforced polyurethane window sash profile and the glass fiber reinforced polyurethane frame profile, and the inner surface of both the glass fiber reinforced polyurethane window sash profile and the glass fiber reinforced polyurethane frame profile is decorated with a film.

[0007] A further provision of this application is that: mounting clips are fixedly installed on one outer surface of both the glass fiber reinforced polyurethane window sash profile and the glass fiber reinforced polyurethane frame profile, and two aluminum alloy exterior decorative panels are installed and fixed on the outer surface of the glass fiber reinforced polyurethane window sash profile and the glass fiber reinforced polyurethane frame profile through corresponding mounting clips.

[0008] The further configuration of this application is as follows: the glass fiber reinforced polyurethane window sash profile has three cavities I, and the two cavities I located on the outdoor side are filled with window sash cavity insulation filling profiles; the glass fiber reinforced polyurethane frame profile has three cavities II, and the three cavities II are filled with frame cavity insulation filling profiles.

[0009] A further feature of this application is that the thermal insulation filling profiles of the window sash cavity and the frame cavity are made of the same material, namely polyurethane foam.

[0010] A further provision of this application is that the total thickness of the aluminum alloy exterior decorative panel and the mounting buckle is 13.8 mm, and the thickness of the coating is 0.2 mm.

[0011] A further provision of this application is that the coating is adhered and fixed to the inner surface of the glass fiber reinforced polyurethane window sash profile and the glass fiber reinforced polyurethane frame profile by PUR hot melt adhesive.

[0012] A further provision of this application is that the aluminum alloy exterior decorative panel is made of aluminum alloy material, and the glass fiber reinforced polyurethane window sash profile and the glass fiber reinforced polyurethane frame profile are both made of glass fiber reinforced polyurethane material.

[0013] This application includes at least one of the following beneficial technical effects:

[0014] 1. The aluminum alloy exterior decorative panel used in this application can prevent the glass fiber reinforced polyurethane door and window profiles from aging due to direct ultraviolet radiation due to their good UV resistance, thus extending the service life of the door and window profiles. In addition, the aluminum alloy surface is smooth and beautiful, enhancing the decorative effect of the door and window profiles.

[0015] 2. The coating made of PE polyester film or PET film in this application is highly flexible and can be tightly adhered to the inner surface of door and window profiles.

[0019] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0020] See Figure 1 This application provides a novel high-performance glass fiber reinforced polyurethane (GFRP) window and door profile with a decorative surface, comprising a GFRP window sash profile 3 and a GFRP frame profile 4. An aluminum alloy exterior decorative panel 1 is fixedly connected to the outer surfaces of both the GFRP window sash profile 3 and the GFRP frame profile 4. A film 2 is applied to the inner surfaces of both the GFRP window sash profile 3 and the GFRP frame profile 4. The film 2 can be made of PE polyester film or PET film, possessing numerous excellent properties such as flexibility, weather resistance, chemical resistance, impact resistance, and scratch resistance. This effectively protects the inner surfaces of the GFRP window sash profile 3 and the GFRP frame profile 4. By using the combination of the aluminum alloy exterior decorative panel 1 and the film 2, the traditional coating process is replaced, effectively reducing production costs and improving the product's market competitiveness.

[0021] In this embodiment, mounting clips 7 are fixedly installed on one outer surface of both the fiberglass reinforced polyurethane window sash profile 3 and the fiberglass reinforced polyurethane frame profile 4. Two aluminum alloy exterior decorative panels 1 are installed and fixed on the outer surfaces of the fiberglass reinforced polyurethane window sash profile 3 and the fiberglass reinforced polyurethane frame profile 4 through the corresponding mounting clips 7. The design of the mounting clips 7 makes the installation process simple and fast, facilitates large-scale production and construction, and shortens the installation cycle.

[0022] In this embodiment, the fiberglass reinforced polyurethane window sash profile 3 has three cavities of different volumes. The two cavities on the outdoor side are filled with window sash cavity insulation filling profile 5. The design of the two outdoor cavities is for installing corner brackets. The middle cavity can provide space for the installation of the actuator and for nailing. The fiberglass reinforced polyurethane frame profile 4 has three cavities of the same volume. The three cavities are filled with frame cavity insulation filling profile 6. The window sash cavity insulation filling profile 5 and the frame cavity insulation filling profile 6 are made of the same material, polyurethane foam, which can further enhance the thermal insulation performance of the fiberglass reinforced polyurethane window and door profile. It should be noted that whether the two outdoor cavities and the three cavities are filled or not can be flexibly adjusted according to the requirements of the overall window heat transfer coefficient.

[0023] In this embodiment, the total thickness of the aluminum alloy exterior decorative panel 1 and the mounting buckle 7 is 13.8 mm, and the thickness of the coating 2 is 0.2 mm.

[0024] In this embodiment, the film 2 is bonded and fixed to the inner surface of the glass fiber reinforced polyurethane window sash profile 3 and the glass fiber reinforced polyurethane frame profile 4 by PUR hot melt adhesive. The method of bonding and fixing the film 2 with PUR hot melt adhesive is environmentally friendly, provides a reliable and stable fixation for the film 2, and has excellent temperature resistance, chemical corrosion resistance and aging resistance, so it is not easy to fall off after long-term use.

[0025] In this embodiment, the aluminum alloy exterior decorative panel 1 is made of aluminum alloy material. The aluminum alloy exterior decorative panel 1, made of aluminum alloy material, can prevent the glass fiber reinforced polyurethane window sash profile 3 and the glass fiber reinforced polyurethane frame profile 4 from being directly exposed to ultraviolet radiation, thereby enhancing the durability and weather resistance of the glass fiber reinforced polyurethane window and door profiles, and also increasing the aesthetics of the glass fiber reinforced polyurethane window and door profiles, making the glass fiber reinforced polyurethane window and door profiles both decorative and practical. The glass fiber reinforced polyurethane window sash profile 3 and the glass fiber reinforced polyurethane frame profile 4 are both made of glass fiber reinforced polyurethane material. Glass fiber reinforced polyurethane material is a high-performance composite material composed of polyurethane matrix and glass fiber reinforcement. The glass fiber reinforced polyurethane window sash profile 3 and the glass fiber reinforced polyurethane frame profile 4 made of glass fiber reinforced polyurethane material can give the glass fiber reinforced polyurethane window and door profiles excellent thermal insulation performance and excellent fire resistance performance.

[0026] With the above structure, the new decorative high-performance glass fiber reinforced polyurethane door and window profile provided in this application, when used, the glass fiber reinforced polyurethane window sash profile 3 and the glass fiber reinforced polyurethane frame profile 4 are made of glass fiber reinforced polyurethane material, which can improve its strength and rigidity, withstand the external forces such as opening and closing of doors and windows, and have excellent fire resistance. During use, it effectively blocks heat transfer and achieves excellent thermal insulation performance.

[0027] The aluminum alloy exterior decorative panel 1 is made of aluminum alloy material. Aluminum alloy has low density but high strength. When installed on the outside of the door and window profile, it forms a protective layer. With its good anti-ultraviolet properties, it prevents the glass fiber reinforced polyurethane door and window profile from being directly exposed to ultraviolet radiation and aging, thus extending the service life of the door and window profile. In addition, the aluminum alloy surface is smooth and beautiful, which enhances the decorative effect of the door and window profile.

[0028] The film 2, made of PE polyester film or PET film, is highly flexible and can be tightly adhered to the inner surface of door and window profiles. With its weather resistance, chemical resistance, impact resistance, and scratch resistance, it effectively resists scratches and corrosion that may occur during daily use, protecting the inner surface of door and window profiles from damage.

[0029] Both the window sash cavity insulation filling profile 5 and the frame cavity insulation filling profile 6 are made of polyurethane foam material. The interior has a porous structure with a large number of closed pores that effectively prevent air convection, further enhancing the thermal insulation performance of the window profiles. The filling situation can be flexibly adjusted according to the overall window heat transfer coefficient requirements to meet different building energy-saving needs.
