Description

Technical Field

[0001] This utility model relates to the field of door and window sealing strip technology, and in particular to a heat-insulating door and window sealing strip. Background Technology

[0002] Traditional doors and windows play a crucial role in building energy conservation, but their thermal insulation performance is often limited by the material and structural design of the sealing strips. While common sealing strip materials possess a certain degree of elasticity and sealing performance, they are prone to aging and deformation under extreme temperature environments, leading to seal failure and increased building energy consumption.

[0003] While existing technologies employ sealing strips made of foamed materials or composite insulation layers, they still suffer from high thermal conductivity. Especially in cold or hot regions, ordinary sealing strips are ineffective at blocking heat transfer, leading to indoor temperature fluctuations and increased air conditioning or heating loads, which does not meet the energy-saving and environmental protection requirements of modern buildings. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a heat-insulating door and window sealing strip.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heat-insulating and heat-preserving door and window sealing strip, comprising a silicone sleeve, a T-shaped strip fixedly connected to the bottom of the silicone sleeve, a first heat insulation layer provided inside the silicone sleeve, a first sound insulation layer provided inside the first heat insulation layer, a second heat insulation layer provided inside the first sound insulation layer, a second sound insulation layer provided inside the second heat insulation layer, and an elastic layer provided inside the second sound insulation layer.

[0006] The T-shaped strip has multiple symmetrical slots on its outer side, and a flexible magnetic strip is fixedly connected to each slot.

[0007] Two anti-slip strips are symmetrically fixed to the bottom surface of the silicone sleeve, and the bottom surface of the anti-slip strips is provided with multiple anti-slip patterns.

[0008] The first heat insulation layer is a polyethylene foam coating, in which hollow glass microspheres are uniformly dispersed.

[0009] The second heat insulation layer is made of nanoporous silica aerogel.

[0010] Both the T-shaped strip and the anti-slip strip are made of EPDM rubber.

[0011] The elastic layer is made of rubber sponge material, and multiple through holes are opened on the outside of the elastic layer. The first sound insulation layer and the second sound insulation layer are melamine resin foam or polyester fiber sound insulation cotton.

[0012] This utility model has the following beneficial effects:

[0013] 1. Compared with existing technologies, this heat-insulating door and window sealing strip adopts a double insulation layer design, combining a polyethylene foam coating containing hollow glass microspheres and aerogel, two low thermal conductivity materials, to doubly block heat transfer. The hollow glass microspheres reduce material density and improve thermal insulation, while the nanoporous structure of the aerogel further reduces heat conduction, effectively copes with extreme temperature environments, reduces indoor and outdoor heat exchange, reduces energy consumption of air conditioning and heating systems, meets green building standards, is suitable for extremely cold, hot and high humidity areas, and can maintain stable performance even in extreme environments.

[0014] 2. Compared with existing technologies, this heat-insulating door and window sealing strip is equipped with a first sound insulation layer and a second sound insulation layer. Combined with the elastic buffering effect of the elastic layer, it absorbs vibrations and external noise when the door and window are closed, improving the indoor acoustic environment. The T-shaped strip enhances the mechanical fit with the window frame, and the flexible magnetic strip assists in sealing through magnetic attraction. The double fixation reduces gaps, and the groove structure prevents the magnetic strip from shifting. It is not easy to fall off after long-term use, has strong weather resistance, is resistant to ultraviolet rays, and is resistant to high and low temperatures, delaying aging and deformation. The anti-slip texture and anti-slip strip prevent the sealing strip from shifting due to external forces. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1 to 3This utility model provides a heat-insulating door and window sealing strip: including a silicone sleeve 2, with a T-shaped strip 1 fixedly connected to the bottom of the silicone sleeve 2, a first heat insulation layer 3 inside the silicone sleeve 2, a first sound insulation layer 4 inside the first heat insulation layer 3, and a second heat insulation layer 5 inside the first sound insulation layer 4. The first heat insulation layer 3 is a polyethylene foam coating, in which hollow glass microspheres are uniformly dispersed. The second heat insulation layer 5 is made of nanoporous silica aerogel. The first heat insulation layer 3, containing hollow glass microspheres, blocks heat convection through its closed-cell foam structure, and the microspheres reflect heat radiation. The second heat insulation layer 5 within the aerogel material utilizes its ultra-low thermal conductivity to block heat conduction paths, forming a highly efficient heat barrier. A second sound insulation layer 6 is provided inside the second heat insulation layer 5, and an elastic layer 7 is provided inside the second sound insulation layer 6. Multiple grooves 10 are symmetrically provided on the outside of the T-shaped strip 1, each... A flexible magnetic strip 11 is fixedly connected to each groove 10. Two anti-slip strips 9 are symmetrically fixed to the bottom surface of the silicone sleeve 2. The bottom surface of the anti-slip strips 9 has multiple anti-slip textures. Both the T-shaped strip 1 and the anti-slip strips 9 are made of EPDM rubber. The elastic layer 7 is made of rubber sponge and has multiple through holes 8 on its exterior. The first sound insulation layer 4 and the second sound insulation layer 6 are made of melamine resin foam or polyester fiber sound insulation cotton. When sound waves pass through the porous fiber structure inside the sound insulation cotton, they are absorbed and converted into heat energy. The through hole structure 8 of the elastic layer 7 further scatters the sound wave energy, reducing mid-to-high frequency noise. When the door and window are closed, the T-shaped strip 1 is deformed under pressure to fill the gap between the window frame. The flexible magnetic strip 11 adsorbs the metal frame to enhance the edge sealing. The anti-slip strips 9 are fixed to the window frame by friction to prevent displacement. The rubber sponge elastic layer 7 rebounds quickly after the pressure is released, avoiding long-term compression deformation and extending its service life.

[0021] The design employs a double-insulation layer, combining a polyethylene foam coating containing hollow glass microspheres and aerogel, two low-thermal-conductivity materials, to effectively block heat transfer. The hollow glass microspheres reduce material density and improve insulation, while the nanoporous structure of the aerogel further reduces heat conduction, effectively coping with extreme temperature environments, reducing indoor-outdoor heat exchange, and lowering energy consumption for air conditioning and heating systems. It meets green building standards and is suitable for extremely cold, hot, and high-humidity regions, maintaining stable performance even under extreme conditions. The first and second sound insulation layers 4, along with the elastic buffering effect of the elastic layer 7, absorb vibrations and external noise when doors and windows are closed, improving the indoor acoustic environment. The T-shaped strip 1 enhances the mechanical fit with the window frame, and the flexible magnetic strip 11 provides magnetic assisted sealing, reducing gaps with double fixation. The groove structure 10 prevents the magnetic strip from shifting, ensuring it is not easily detached over long-term use. It is highly weather-resistant, UV-resistant, and resistant to high and low temperatures, delaying aging and deformation. Anti-slip textures and anti-slip strips 9 prevent the sealing strip from shifting due to external forces.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
