Description

Technical Field

[0001] This utility model relates to the field of door and window profile technology, and more specifically, to a novel energy-saving door and window structure formed by co-extrusion molding. Background Technology

[0002] Aluminum alloy doors and windows refer to doors and windows made with aluminum alloy extruded profiles as frames, mullions, and sashes, or simply aluminum doors and windows. Aluminum alloy doors and windows also include those made with aluminum alloy as the load-bearing structure (the structure that bears and transmits its own weight and load) and plastic composite material, also known as aluminum-plastic composite doors and windows or aluminum-plastic co-extruded doors and windows.

[0003] With the continuous improvement of building energy efficiency standards, the thermal insulation performance of doors and windows, as a weak link in the building envelope, is receiving increasing attention. Currently, most energy-saving doors and windows on the market use thermally broken aluminum alloy profiles, which use thermal break strips inside the aluminum profiles to block the heat conduction path.

[0004] To improve heat insulation and sound insulation, aluminum alloy doors and windows not only use heat-insulating materials to set thermal breaks on the inside and outside of the door and window profiles, but also have a cladding layer on the inside of the profiles to improve the heat insulation and sound insulation of the aluminum alloy door and window profiles. However, the commonly used cladding layer is made of PVC material, but after long-term use, PVC material will age and deform, and is easy to fall off the aluminum alloy profile, affecting the overall structural stability and energy-saving heat insulation effect.

[0005] Therefore, it is necessary to propose a new energy-saving door and window structure based on co-extrusion molding to solve the problems existing in the current technology. Utility Model Content

[0032] like Figure 1-5 As shown, this utility model provides a novel energy-saving door and window structure formed by co-extrusion, including an indoor frame 1 and an outdoor frame 2 arranged opposite to each other. The indoor frame 1 and the outdoor frame 2 are connected by a connector 3. A heat insulation cavity is provided on the inner side of the indoor frame 1 and the outdoor frame 2. A covering layer 4 is fixedly provided on the inner surface of the indoor frame 1 and the outdoor frame 2 and the outer surface of the heat insulation cavity. A weather-resistant layer 5 co-extruded with the covering layer 4 is provided on the outer side of the covering layer 4.

[0033] Furthermore, the interior frame 1 includes a first interior frame 11 and a second interior frame 12, which are arranged side by side;

[0034] The heat insulation cavity includes a first heat insulation cavity 13 and a second heat insulation cavity 14. The first heat insulation cavity 13 is fixedly disposed on the inner surface of the first indoor frame 11, and the second heat insulation cavity 14 is fixedly disposed on the inner surface of the second indoor frame 12.

[0035] Furthermore, the outdoor frame 2 includes a first outdoor frame 21 and a second outdoor frame 22, which are arranged side by side;

[0036] The insulation cavity also includes a third insulation cavity 23 and a fourth insulation cavity 24. The third insulation cavity 23 is fixedly installed on the inner surface wall of the first outdoor frame 21, and the fourth insulation cavity 24 is fixedly installed on the inner surface wall of the second outdoor frame 22.

[0037] Furthermore, the third heat insulation cavity 23 includes an outer cavity 231 and an inner cavity 232, which are arranged along a direction perpendicular to the inner surface of the first outer frame 21;

[0038] The fourth insulation cavity 24 includes a front cavity 241 and a rear cavity 242, which are arranged along a direction perpendicular to the inner surface of the second outer frame 22.

[0039] Furthermore, the outer wall of the outer cavity 231 is fixedly connected to the outer wall of the inner cavity 232, and the outer wall of the front cavity 241 is fixedly connected to the outer wall of the rear cavity 242.

[0040] Furthermore, wedge-shaped grooves 6 are provided on the outer walls of the outer cavity 231 and the inner cavity 232 respectively;

[0041] Both ends of the thermal insulation connector 7 are fixedly provided with wedge-shaped locking blocks 71, which are engaged in the wedge-shaped locking groove 6.

[0042] Furthermore, two wedge-shaped slots 6 are arranged in parallel.

[0043] Furthermore, several connecting buckles 8 are fixedly installed on the inner surface of the indoor frame 1 and the outdoor frame 2 and on the outer surface of the insulation cavity. The shape of the connecting buckles 8 is T-shaped, Y-shaped, L-shaped or trapezoidal, and the covering layer 4 is wrapped around the connecting buckles 8.

[0044] Furthermore, the outer surfaces of the indoor frame 1 and the outdoor frame 2 are fixedly provided with an anodized layer, fluorocarbon coating, ceramic coating, powder coating or wood grain transfer layer.

[0045] Furthermore, the weather-resistant layer 5 is made of ASA resin material.

[0046] The working principle of the above technical solution:

[0047] The energy-saving door and window profile includes an interior frame 1 and an exterior frame 2 arranged opposite to each other. The interior frame 1 and the exterior frame 2 are connected by a connector 3. A heat insulation cavity is provided on the inner side of the interior frame 1 and the exterior frame 2. A covering layer 4 is fixedly provided on the inner surface of the interior frame 1 and the exterior frame 2 and the outer surface of the heat insulation cavity. A weather-resistant layer 5 co-extruded with the covering layer 4 is provided on the outer side of the covering layer 4. The covering layer 4 can be made of polycarbonate or acrylonitrile material, and the weather-resistant layer 5 is made of ASA resin material. The weather-resistant layer 5 protects the covering layer 4 from direct contact with oxygen, making the covering layer 4 less prone to aging and improving the overall structural strength.

[0048] The indoor frame 1 includes a first indoor frame 11 and a second indoor frame 12, which are arranged side by side. The outdoor frame 2 includes a first outdoor frame 21 and a second outdoor frame 22, which are arranged side by side.

[0049] The first indoor frame 11 and the first outdoor frame 21 are connected by connector 3 to form a glass side frame for installing glass. The second indoor frame 12 and the second outdoor frame 22 are connected by connector 3 to form a wall side frame, which is fixed to the wall during installation. An elastic connector is provided between the glass side frame and the wall side frame to provide elastic space when the glass expands and contracts due to heat. The glass side frame and the wall side frame can be installed in stages. Installing the wall side frame first can prevent the glass from breaking during construction. The glass side frame is installed after the wall side frame is installed.

[0050] The heat insulation cavity includes a first heat insulation cavity 13 and a second heat insulation cavity 14. The first heat insulation cavity 13 is fixedly disposed on the inner surface of the first indoor frame 11, and the second heat insulation cavity 14 is fixedly disposed on the inner surface of the second indoor frame 12.

[0051] The third heat insulation cavity 23 and the fourth heat insulation cavity 24 are fixedly installed on the inner surface wall of the first outdoor frame 21, and the fourth heat insulation cavity 24 is fixedly installed on the inner surface wall of the second outdoor frame 22.

[0052] Since the glass side frame and the wall side frame need to be connected using connector 3, if a covering layer 4 is installed at the location where connector 3 is installed, the strength of the covering layer 4 is more related to the strength of the aluminum alloy frame body, which will affect the connection strength. Therefore, connector 3 is connected to the aluminum alloy frame body. In order to reduce the heat conduction of air between the aluminum alloy frames, a heat insulation cavity is set up to reduce heat transfer. The third heat insulation cavity 23 is divided into an outer cavity 231 and an inner cavity 232. The setting of the two cavities further reduces the heat transfer of air. A heat insulation connector 7 is set between the outer cavity 231 and the inner cavity 232 to further block the heat conduction between the indoor frame 1 and the outdoor frame 2.

[0053] Wedge-shaped grooves 6 are provided on the outer walls of the outer cavity 231 and the inner cavity 232, respectively. Wedge-shaped blocks 71 are fixed to both ends of the thermal insulation connector 7, and the wedge-shaped blocks 71 engage with the wedge-shaped grooves 6. Two parallel wedge-shaped grooves 6 are provided. Two thermal insulation connectors 7 are provided between the outer cavity 231 and the inner cavity 232 to improve the stability of the connection between them. This enhances the energy-saving and thermal insulation effect while increasing the overall structural strength.

[0054] To prevent the covering layer 4 from falling off the indoor frame 1 and the outdoor frame 2, several connecting buckles 8 are fixedly installed on the inner surface of the indoor frame 1 and the outdoor frame 2 and the outer surface of the insulation cavity. The connecting buckles 8 are T-shaped, Y-shaped, L-shaped or trapezoidal. The covering layer 4 is wrapped around the connecting buckles 8, which improves the firmness of the connection between the covering layer 4 and the indoor frame 1, the outdoor frame 2 and the insulation cavity.

[0055] Anodized layer, fluorocarbon coating, ceramic coating, powder coating or wood grain transfer layer are fixedly applied to the outer surface of the indoor frame 1 and the outdoor frame 2 to improve the aesthetics and surface anti-aging performance of the exposed parts of the indoor frame 1 and the outdoor frame 2.

[0056] Connector 3 can be a thermal insulation strip, which can be made of nylon material (PA66). The thermal insulation strip can isolate the direct heat conduction of the aluminum alloy frame body, but it cannot isolate the heat conduction of the air inside the aluminum alloy frame. Although the thermal conductivity of air is low, if the outdoor air cools down and the indoor air heats up, forming a circulation inside the aluminum alloy frame, the heat conduction cannot be ignored.

[0057] New energy-saving door and window structure manufacturing process based on co-extrusion molding:

[0058] 1. Aluminum alloy pretreatment stage:

[0059] ① First, A00 aluminum ingots (aluminum rods) are put into the furnace for heating and smelting;

[0060] ②When the aluminum alloy reaches a certain temperature, the aluminum alloy raw material in the furnace is extruded into a profile substrate through the mold corresponding to the aluminum alloy profile drawing. The extruded profile substrate is in the shape of a long strip, which is then cut to the required length.

[0061] ③ Surface treatment of extruded aluminum alloy profile substrates (including but not limited to electrostatic powder coating, anodizing, fluorocarbon process, wood grain transfer process, ceramic coating process, etc.) to increase the aesthetics and durability of the profiles.

[0062] 2. Co-extrusion composite stage:

[0063] ① Adopts dual extruders working in tandem;

[0064] ② The main extruder is adapted to the corresponding mold, and the aluminum alloy profile is first injection molded to form a coating layer 4 at the coating position;

[0065] ③ The injection molding composite post-extrusion machine is adapted to the corresponding mold to perform surface co-extrusion on the co-extrusion surface of the injection surface. The co-extrusion surface material is alloy resin ASA to form a weather-resistant layer 5. The thickness of the co-extrusion surface layer is about 0.5mm. Alloy resin ASA has good weather resistance, UV resistance, high gloss, good mechanical properties and chemical resistance.

[0066] ④ Online embossing and cooling system: Embossing rollers are designed at the rear end of the co-extrusion die. After the profile is co-extruded by the main and auxiliary extruders, it continues to move towards the rear end and is embossed on the surface of the co-extruded layer by the embossing rollers. The embossing pattern can be changed by changing the embossing rollers with different textures. (Stage cooling: water cooling section (40-60℃) → air cooling section (room temperature)).

[0067] 3. Post-processing techniques:

[0068] The cross-sectional profiles after co-extrusion are then laminated with strips.

[0069] The beneficial effects of the above technical solution are as follows:

[0070] The novel energy-saving door and window structure produced by co-extrusion of this utility model has a heat insulation cavity set on the inner surface of the indoor frame and the outdoor frame, and a covering layer is fixedly set on the inner surface of the indoor frame and the outdoor frame and the outer surface of the heat insulation cavity to improve the energy-saving effect. A weather-resistant layer is set on the outside of the covering layer to protect the covering layer, improve the surface flatness of the covering layer and prevent the covering layer from aging, thereby improving the heat insulation effect and the overall structural stability.
