Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy profile technology, and in particular to a heat-insulating aluminum alloy composite profile. Background Technology
[0002] Currently, Chinese Patent Publication No. CN108215046A discloses a strip-insertion method for internal cavity polyurethane foamed aluminum profiles and molding equipment. The profile includes a strip-insertion method for internal cavity polyurethane foamed aluminum profiles. Polyurethane foam strips are filled into cavity A, which is enclosed by aluminum profiles A and B and strips A and B. A U-shaped paper strip is positioned between strips A and the polyurethane foam strip. Strips A and B are made of plastic. The lengths of the molded U-shaped paper strip, polyurethane foam strip, and strip-insertion aluminum profile are equal, and their end faces are aligned. This discloses existing strip-insertion type thermal insulation materials. (The specification includes an appendix.) Figure 6 The article discloses existing injection-molded thermal insulation profiles.
[0003] With the advancement of the national carbon neutrality goal, there are high requirements for energy conservation in doors and windows, especially for thermally insulated aluminum profiles. Existing strip-type thermal insulation materials have long cross-sectional lengths and become soft, making them unable to provide effective support. Injection-type materials have low volume density and cannot meet energy conservation requirements. Utility Model Content
[0004] Therefore, in view of the above problems, this utility model proposes a heat-insulating aluminum alloy composite profile, which solves the above technical problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heat-insulating aluminum alloy composite profile, comprising an inner aluminum profile, an outer aluminum profile spaced apart from the inner aluminum profile, and a composite component detachably connected to the inner and outer aluminum profiles respectively. The inner aluminum profile has an inner suspension portion on the side near the composite component, and an inner hook is provided on the inner suspension portion near the middle of the inner aluminum profile. The outer aluminum profile has an outer suspension portion on the side near the composite component, and an outer hook is provided on the outer suspension portion near the middle of the outer aluminum profile. The composite component comprises a polyurethane outer frame and a foam layer filled inside the polyurethane outer frame. The polyurethane outer frame has a left inner groove on one lateral side that cooperates with the inner suspension portion and inner hook on the inner aluminum profile, and a right inner groove on the other lateral side that cooperates with the outer suspension portion and outer hook on the outer aluminum profile.
[0006] Furthermore, the polyurethane outer frame is a connecting plate spaced between the upper and lower ends of the inner and outer aluminum profiles, and the foaming layer is disposed between the connecting plates.
[0007] Furthermore, the polyurethane outer frame is rectangular in shape, and the foaming layer is disposed in the inner groove of the polyurethane outer frame.
[0008] Furthermore, the length of the polyurethane outer frame cross-section is 25-75cm, and the width of the polyurethane outer frame cross-section is 15-50cm.
[0009] Furthermore, the polyurethane outer frame is provided with reinforcing ribs at the middle position of the foam layer.
[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:
[0011] This thermally insulated aluminum alloy composite profile, through the addition of a foam layer, increases the deformation resistance of the polyurethane outer frame. Compared to right-facing strip-type thermal insulation materials, its cross-sectional length and width can be increased, resulting in greater insulation space and improved thermal insulation performance. Furthermore, due to the internal foam layer, compared to existing injection-type thermal insulation profiles, the injection area is larger, leading to better thermal insulation performance. This solves the problems of existing strip-type thermal insulation materials, which become softer with longer cross-sectional lengths, failing to provide effective support; and injection-type materials, which have low volume density and cannot meet energy-saving requirements.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0019] refer to Figures 1 to 6This embodiment provides a heat-insulating aluminum alloy composite profile, including an inner aluminum profile 1, an outer aluminum profile 2 spaced apart from the inner aluminum profile 1, and a composite component 3 detachably connected to the inner aluminum profile 1 and the outer aluminum profile 2 respectively. The inner aluminum profile 1 has an inner hanging portion 101 near the composite component 3, and an inner hook 102 is provided on the inner hanging portion 101 near the middle of the inner aluminum profile 1. The outer aluminum profile 2 has an outer hanging portion 201 near the composite component 3. The part 201 is provided with an outer hook 202 near the middle of the outer aluminum profile 2. The composite part 3 includes a polyurethane outer frame 301 and a foam layer 302 filled inside the polyurethane outer frame 301. The polyurethane outer frame 301 has a left inner groove 303 on one side of the lateral direction that cooperates with the inner hanging part 101 and the inner hook 102 on the inner aluminum profile 1. The polyurethane outer frame 301 has a right inner groove 304 on the other side of the lateral direction that cooperates with the outer hanging part 201 and the outer hook 202 on the outer aluminum profile 2.
[0020] The addition of a foam layer increases the deformation resistance of the polyurethane frame. Compared to right-facing strip-type insulation materials, the cross-sectional length and width can be increased, increasing the insulation space and improving insulation performance. At the same time, due to the internal filling with a foam layer, the injection area is larger and the insulation performance is better than existing injection-type insulation profiles.
[0021] The polyurethane outer frame 301 is a connecting plate spaced between the upper and lower ends of the inner aluminum profile 1 and the outer aluminum profile 2. The foamed layer 302 is disposed between the connecting plates. (See reference...) Figure 1 When the connecting plate is spaced at both ends, the amount of polyurethane outer frame material is small, and it needs to be bonded and fixed with the foam layer to increase the bonding strength, resulting in low cost.
[0022] The polyurethane outer frame 301 is rectangular in shape, and the foamed layer 302 is disposed in the inner groove of the polyurethane outer frame 301, as can be referenced. Figure 2 With this structure, the polyurethane outer frame has high strength, and due to the internal foam filling layer, it has good resistance to deformation and excellent performance.
[0023] The polyurethane outer frame 301 has a cross-sectional length of 25-75cm and a cross-sectional width of 15-50cm. Preferably, the cross-sectional length is 60cm and the cross-sectional width is 30cm. Existing thermally insulated aluminum alloy composite profiles typically have a cross-sectional length and width of 10-15cm. Due to the tendency to soften when lengthened or with added thermal insulation strips, the dimensions are usually smaller. The composite component can be set to a length of about 60cm and a width of about 30cm. By injecting a foam layer into the interior of the composite component, the thermal insulation performance is increased. Due to the volume and the addition of the internal foam layer, the thermal insulation performance during use is enhanced. Furthermore, due to the reinforcing rib injected in the middle, even if the length or width of the composite component increases, the reinforcing rib has a certain degree of rigidity and support. By being secured in the middle of the polyurethane outer frame, the problem of softening when the cross-sectional length and width of the polyurethane outer frame increase can be prevented.
[0024] The polyurethane outer frame 301 has a reinforcing rib 4 located in the middle of the foam layer 302. The reinforcing rib 4 is filled with glass fiber, but it can also be replaced with existing polymer fiber filler, iron core board, aluminum core board or other rigid materials that achieve the same function.
[0025] The polyurethane outer frame 301 has V-shaped edges 3a on both sides inside. The polyurethane outer frame 301 has reinforcing blocks 3b that fit with the V-shaped edges 3a inside. The reinforcing blocks are cross-shaped. A round tube 3c is provided in the middle of the reinforcing block 3b. The reinforcing blocks and the round tube have cross sections 3d that are spaced apart in the middle. A through hole 3e is provided on the outside of the round tube.
[0026] In use, first insert the reinforcing block into the V-shaped edge inside the polyurethane outer frame. The V-shaped edge will fix the reinforcing block. After completion, cover the front and back of the reinforcing block and leave a central hole at the through hole position of the reinforcing block. Then insert the foaming agent injection tube. After the foaming agent reaches the middle of the reinforcing block through the round tube, it fills the inner groove and cross-section of the polyurethane outer frame to form a foam layer. Move it out towards the round hole of the round tube to fill the non-cross-section area inside the polyurethane outer frame. After filling, remove the front and back blocking positions of the reinforcing block. Compared with the reinforcing ribs, this structure is more convenient for injecting foaming agent. The filling process of the original reinforcing ribs is complicated. Moreover, the cross-shaped reinforcing block has higher strength and is less likely to deform and bend under stress. Since the internal foam layer is connected and fixed to the reinforcing block through the cross-section and through hole, it is less likely to break and fall off from the polyurethane outer frame, greatly extending the service life.
