Description

Technical Field

[0001] This utility model relates to the field of building energy conservation technology, and in particular to a low-energy-consumption thermal insulation aluminum material. Background Technology

[0002] Building doors and windows are an important component of the building envelope. Besides meeting various functional and performance requirements, they also bear significant responsibility for energy conservation. Currently, the world is undergoing unprecedented changes, and international trade protectionism is on the rise. Existing ultra-low energy consumption aluminum alloy doors and windows and passive doors and windows in my country use single-thermal-break aluminum alloy profiles with PA66 nylon insulation widths of 55-65mm, combined with triple-glazed double-cavity insulated glass. After employing warm edge strips, single or double silver Lov-e insulation, and argon filling processes, their ultimate U-value is approximately ≥1.0. The EU (CEN) EN14351-2023 standard has been implemented, raising the limit from the original standard of 1.4W / (m²) to 1.0. 2 The drop in U value to 0.8 has forced Chinese door and window companies to break through the technical barrier of 0.8 and align with international standards.

[0003] To improve building energy efficiency and align with international standards, the energy efficiency standards for new buildings in 2025 will be 30% higher than those in 2020. The heat transfer coefficient (U-value) of doors and windows is required to be ≤1.5 (≤1.2 in extremely cold regions). Traditional thermally broken aluminum doors and windows (U-value ≥1.8) face the risk of being phased out. In order to meet the people's needs for high-quality housing, promote the application of new technologies, equipment, materials and products, and drive the construction of safe, comfortable, green and smart "good houses".

[0004] Therefore, it is essential to provide an ultra-low energy consumption thermal insulation aluminum material to support the transformation and upgrading of the construction industry, high-quality development, and to break through the EU's technical barriers to my country.

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an ultra-low energy consumption thermal insulation aluminum material.

[0007] The inner profile body is a thermal break structure; the inner profile body includes an inner panel and an inner profile; the inner panel and the inner profile are connected by a second thermal insulation structure; a first insulation layer is co-extruded on both sides of the second thermal insulation structure, and the end of the first insulation layer on one side of the second thermal insulation structure forms a functional groove for hardware or pressure strips between it and the inner profile; the functional groove includes those for glass pressure strip installation or hardware accessory installation.

[0013] The first heat insulation structure includes at least two first heat insulation strips; the inner profile body and the outer profile body are each provided with a third slot; the two ends of the first heat insulation strip are respectively engaged in the third slots on the corresponding inner profile body and outer profile body sidewalls, and a second heat insulation cavity is formed between the inner profile body, the outer profile body and the first heat insulation strip; the second heat insulation cavity is filled with heat insulation filler.

[0014] Both the inner profile body and the outer profile body have corner bracket cavities at the locations corresponding to the first thermal insulation structure.

[0015] A method for preparing an ultra-low energy consumption thermal insulation aluminum material includes the following steps:

[0016] S1: Prepare the inner profile body according to the required U value;

[0017] S2: Prepare the outer profile body according to the required U value;

[0018] S3: Connect the inner profile body and the outer profile body through the first heat insulation strip, and fill the second heat insulation cavity formed by the inner profile body, the outer profile body and the first heat insulation strip with heat insulation filler.

[0019] The inner profile body in S1 has two types: one is a non-broken bridge structure and the other is a broken bridge structure. When the broken bridge structure inner profile body is selected, the first insulation layer needs to be co-extruded at the broken bridge of the inner profile body, and the first insulation layer on one side forms an installation groove with the inner profile body.

[0020] The outer profile body in S2 has two types: one is a non-broken bridge structure and the other is a broken bridge structure. When the broken bridge structure outer profile body is selected, a second insulation layer needs to be co-extruded at the broken bridge of the outer profile body, and the second insulation layer on one side needs to cover the second cavity on the outer plate of the outer profile body.

[0021] The above technical solution has the following beneficial effects: (1) At least one of the inner profile body and the outer profile body of the present invention is a broken bridge structure. The specific structure of the inner profile body and the outer profile body can be selected according to the required K value or U value. At the same time, the first heat insulation structure connects the outer profile body and the inner profile body to form multiple thermal resistance barriers. With the first heat insulation layer and / or the second heat insulation layer co-extruded on both sides, the K value or U value of the profile composed of the inner profile body and the outer profile body is diversified, so as to meet the needs of different customers.

[0022] (2) When the inner profile body or the outer profile body is selected with a thermal break structure, the present invention forms a double thermal break structure. It can be equipped with triple-glazed double-cavity or double-glazed single-cavity insulated glass and optional processes or methods such as nylon spacer strip single silver or double silver Lov-e, laminated insulated glass, and argon gas filling in the insulated cavity. It can be matched to produce high-performance doors and windows with different K values ​​or U values ​​of less than or equal to 1.0 to 1.5, with a wider range of applications, meeting the personalized needs of engineering projects and reducing costs.

[0023] (3) When both the inner profile body and the outer profile body adopt the thermal break structure, this utility model constitutes a triple thermal break structure. It can be equipped with processes or methods such as four-glass three-cavity, three-glass two-cavity and optional nylon spacer strip, single silver or double silver Lov-e, laminated insulated glass, argon gas filling in the hollow cavity, vacuum glass, etc. It can be combined to create passive doors and windows with K value or U value less than or equal to 0.6 to 0.8, breaking through the technical barrier of the new standard U value of 0.8;

[0024] (4) The first and second insulation layers of this utility model are co-extruded inside, which can solve the problems of the co-extruded layer being exposed to the outdoors, being not weather-resistant, brittle, and easy to fade.

[0025] (5) The corner cavity of the corner bracket assembly of this utility model can be designed with or without a plastic co-extruded insulation layer. The influence on the insulation K value or U value can be ignored. On the contrary, the advantage of not designing a co-extruded insulation layer here is that the door and window processing assembly process can be completely the same as the existing thermally broken aluminum window process, such as corner injection, pin injection and active expansion corner bracket injection. Existing door and window companies do not need to purchase or add special production equipment, and do not need to carry out technical training and other related work before production. This is more conducive to the market promotion and application of the product.

[0026] (6) The visible panel of the outer or inner profile body of this utility model is still a metallic aluminum alloy profile, and its weather resistance, aesthetics, and scratch prevention are exactly the same as those of the existing thermally broken aluminum profile. At the same time, a first cavity and a second cavity are set on the outer panel, and the width of the first cavity is less than or equal to 2-3 mm; the width of the second cavity is less than or equal to 1.5-3 mm. This can effectively control the heat from the outside or inside the window and effectively prevent the heat from the inside or outside from seeping in or dissipating through the window, reduce the exchange of heat between the inside and outside, reduce heating and cooling energy consumption, avoid energy loss due to cold or heat bridges, help maintain stable indoor temperature, and correct the drawback of the thermal insulation cavity being set in the middle of the window in the background technology, which affects the overall window insulation performance. This utility model has an extremely low heat transfer coefficient and is the preferred new composite aluminum material for high-performance and passive doors and windows in green building "good houses".

[0044] A method for preparing an ultra-low energy consumption thermal insulation aluminum material includes the following steps:

[0045] S1: Prepare the inner profile body 1 according to the required U value;

[0046] S2: Prepare the outer profile body 2 according to the required U value;

[0047] S3: Connect the inner profile body 1 and the outer profile body 2 through the first heat insulation strip, and fill the second heat insulation cavity formed by the inner profile body 1, the outer profile body 2 and the first heat insulation strip with heat insulation filler 8.

[0048] Furthermore, the inner profile 1-2 in S1 has two types of bodies: one is a non-broken bridge structure and the other is a broken bridge structure. When the inner profile body 1 with a broken bridge structure is selected, the first insulation layer 5 needs to be co-extruded at the broken bridge of the inner profile body 1, and the first insulation layer 5 on one side forms a functional groove 6 with the inner profile body 1.

[0050] Furthermore, the preparation method of the inner profile body 1 and the outer profile body 2 in this embodiment includes the following steps:

[0051] 1. Aluminum profile pretreatment: The aluminum profile is melted or sprayed to form a porous activated layer and a composite molding including thermal break aluminum lining. A layer of epoxy resin lining is evenly sprayed or brushed on the surface of the aluminum lining profile or thermal break composite aluminum lining profile and then dried by hot air or UV curing.

[0052] 2. Co-extrusion molding: An aluminum-lined profile conveyor transports the aluminum-lined profile, which includes non-broken bridge aluminum lining and broken bridge composite aluminum lining, into the center hole of the molding die; an extruder extrudes the first insulation layer in the inner profile body 1 and the second insulation layer 7 in the outer profile body 2 in two batches. The first insulation layer 5 is made of rigid polyvinyl chloride plastic, and the second insulation layer 7 can be made of micro-foamed polyvinyl chloride plastic. The two batches are fed into the outer layer inlet and the middle layer inlet of the molding die respectively, and the composite structure of the aluminum-lined profile plastic layer is completed in the molding die.

[0053] 3. Layered Shaping: The two-layered composite structure output from the forming mold is pulled into the shaping mold for cooling and shaping; in this step:

[0054] The aluminum-lined profiles are clamped by the rubber material on the surface of the conveyor's drive wheel, and the conveying speed and profile traction speed are 1.0 to 1.5 meters per minute;

[0055] The first insulation layer 5 and the second insulation layer 7 are respectively made of rigid polyvinyl chloride plastic with a molding temperature of 175-180℃ and micro-foamed polyvinyl chloride plastic with a molding temperature of 155-165℃; the weight ratio of heat stabilizing agent added to the micro-foamed polyvinyl chloride plastic is 5.5%, and the weight ratio of foaming agent added is 2.5% to 3.5%.

[0056] The foaming density of micro-foamed polyvinyl chloride (PVC) plastic is determined by the weight of the foaming agent added. When the weight ratio of the added foaming agent is 2.5%, a soft and lightweight micro-foamed plastic layer with a density of 0.7-0.8 g / cm³ can be obtained. This layer is applied to the first insulation layer 5. More preferably, the soft and lightweight micro-foamed plastic layer reduces the weight per meter of the profile, thereby reducing costs. When the weight ratio of the added foaming agent is 3.5%, a moderately hard foamed layer with a density of 1.1-1.2 g / cm³ can be obtained. This relatively hard micro-foamed plastic layer is applied to the second insulation layer 7. More preferably, it ensures the required hardness of the co-extruded layer on the visible surface, ensuring reliable high impact resistance and preventing easy scratches that affect the aesthetic appearance of the profile surface.

[0057] The melt pressure during PVC molding is 20-25 WPa, and the filler content is 70%-80% by weight of the profile plastic. The temperature for rigid PVC molding is 175-185℃; the temperature for micro-foamed PVC molding is 155-165℃.

[0058] 4. Traction and cutting

[0059] While co-extruding rigid plastic or micro-foamed plastic and aluminum liner for molding and shaping, the co-extrusion profile traction machine is started; wherein: the traction direction is the profile extrusion direction, and the traction speed is the profile extrusion speed of 1.0 to 1.5 meters / minute; the profiles that run continuously after traction are cut into sections at the aluminum liner joints according to the aluminum liner length, generally 6 meters / piece, and concentrated in sections.

[0060] Furthermore, the surface treatment of the visible outer surface of the second insulation layer 7 is existing technology, including coating, film coating, etc.

[0061] 5. Tooth cutting, strip threading, and rolling.

[0062] The outer profile body 2 and the inner profile body 1 are cut by a toothing machine. After toothing, the aluminum profile is inserted with PA66 nylon strips and thermal insulation strips that meet the height of the drawings according to the design requirements. The inserted thermal insulation strips are rolled by a rolling machine to become a thermal insulation type aluminum-plastic co-extruded composite profile.

[0063] In this embodiment, at least one of the inner profile body 1 and the outer profile body 2 of the ultra-low energy consumption thermal insulation aluminum material is a thermally broken structure. The specific structure of the inner profile body 1 and the outer profile body 2 can be selected according to the required U value. At the same time, the first thermal insulation structure 3 connects the outer profile body 2 and the inner profile body 1 to form multiple thermal resistance barriers. With the first thermal insulation layer 5 and / or the second thermal insulation layer 7 co-extruded on both sides, the U value of the profile composed of the inner profile body 1 and the outer profile body is diversified, thereby meeting the needs of different customers.

[0064] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
