Description

Technical Field

[0001] The invention relates to the field of thermal insulation materials, and in particular to a hollow tubular thermal insulation material. Background Art

[0002] To address the issue of insufficient warmth retention in humid conditions caused by current pure natural cotton and animal hair fabrics, major textile companies around the world have developed various structural types of single-cavity or multi-cavity hollow microfiber insulation materials. For example, Thinsulate insulation materials are currently manufactured using ultra-fine hollow fibers that are 10 times thinner than ordinary fibers, approximately 2-5 microns, to improve the thermal insulation performance of the material while maintaining softness, comfort, and intelligent resilience.

[0003] This method improves air retention and insulation by increasing fiber surface area within the same fill volume. American Climasheld hollow ultrafine polyester filament insulation cotton addresses the issue of moisture and water infiltration affecting insulation stability. This requires a hollow ultrafine filament structure to minimize moisture ingress through the hollow cross-section, improving water repellency and providing moisture-proof, quick-drying, and breathable insulation. Supreme thermal insulation cotton: It is a mixture of three hollow ultra-fine polyester fibers, including 10% environmentally friendly recycled polyester fiber. The unique mixing process enables the material to have natural "clusters" like high-quality down. The ability of this structure has the following shortcomings: 1. The ultra-fine hollow short fiber structure has the advantage of good resilience, but the short fiber hollow structure has no water-repellent, moisture-proof and quick-drying effects, which are not as good as the ultra-fine hollow long fiber in the thermal insulation effect in a humid environment.

[0004] Current hollow fiber insulation materials utilize ultra-fine hollow through-hole tubes, rather than sealing the entire tube in sections or segments. Temperature fluctuations and external forces can cause the sealed hollow tube to deform and rupture under pressure, degrading the water and moisture resistance of the hollow tubular insulation material. This compromises the thermal insulation stability. This material and technical solution results in complex manufacturing processes and high costs.

[0005] This proposal designs a hollow tubular thermal insulation material with a simple manufacturing process, low cost, reliable and stable performance, and can be widely used in thermal insulation and heat insulation fields such as clothing, construction, and transportation.

[0006] Invention patent content

[0007] The hollow tubular thermal insulation material proposed in this patent solves the water-proof and moisture-proof problems of the hollow tubular thermal insulation materials in the prior art, improves the moisture-proof, heat-insulating and thermal-insulating stability of the hollow thermal insulation materials, and expands the scope of application.

[0008] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] A hollow tubular thermal insulation material comprises a hollow tubular thermal insulation material body and a pipe body pressure relief expansion joint, wherein the pipe body pressure relief expansion joint is arranged on the hollow tubular thermal insulation material body, and the pipe body pressure relief expansion joint is formed by locally extruding a molding die on the hollow tubular thermal insulation material body, and the two ends of the tube cavity of the hollow tubular thermal insulation material body are arranged as a fully sealed structure to form the hollow tubular thermal insulation material.

[0010] Preferably, the pipe body pressure relief expansion joint is a retractable folding or pleated structure.

[0011] Preferably, the cavity of the hollow tubular thermal insulation material is filled with an inert gas.

[0012] Preferably, multiple sections of pipe body pressure relief expansion joints are provided on the same hollow tubular heat-insulating material pipe body sealing section.

[0013] Beneficial effects of the present invention:

[0014] 1. Since both ends of the hollow tubular insulation material are set as a fully sealed structure, the insulation material solves the problems of water resistance, moisture resistance and thermal insulation stability in a humid environment;

[0015] 2. The setting of the pipe body pressure relief expansion joint enables the sealed hollow tubular insulation material to generate a rebound space for stretching, deformation and buffering when subjected to various cold and hot air pressures, internal and external forces. This solves the problem of unstable water-blocking, moisture-proof and thermal insulation performance of the insulation material caused by water ingress and permeation into the closed hollow tubular insulation pipe cavity due to pressure rupture;

[0016] 3. Filling the hollow tubular heat-insulating material cavity with the pipe body pressure relief expansion joint with an inert gas can reduce the loss of heat preservation and thermal insulation performance caused by air heat conduction in the hollow cavity;

[0017] 4. The fully sealed structure of the hollow tubular insulation material and the design of the pressure relief expansion joint of the pipe body can ensure the water-blocking, moisture-proof and thermal insulation stability of the hollow tubular insulation material of any wire diameter and pipe diameter in a humid environment.

[0018] 5. The pressure relief expansion joint of the insulation pipe body is extruded by a plastic mold and can be produced in batches and on a large scale.

[0019] The patented invention has a reasonable structure, ingenious design, and simple operation. It can achieve stable and effective water-blocking, moisture-proof, and heat-insulating properties, as well as maintain a stable elastic heat-insulating state for the hollow heat-insulating pipe cavity. It can also be produced in large quantities, solving the problems of complex manufacturing process, high cost, and narrow scope of use of heat-insulating pipes in the prior art, and is easy to promote and use.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0033] Reference Figure 1-6 A hollow tubular thermal insulation material comprises a hollow tubular thermal insulation material body 1 and a tube body pressure relief expansion joint 3. The hollow tubular thermal insulation material body 1 is extruded and molded between a molding upper mold 5 and a molding lower mold 6 to form a tube body pressure relief expansion joint 3. The upper sealing block 7 and the lower sealing block 8 at the front and rear ends of the molding molds 5 and 6 are then used to seal the two ends of the tube cavity 2 of the hollow tubular thermal insulation material body to form a tube body sealing joint 4.

[0034] In this embodiment, the pipe body pressure relief expansion joint 3 is formed by extruding the upper and lower molding dies 5 and 6 on the hollow tubular heat-insulating material pipe body 1. The pipe body pressure relief expansion joint 3 is an elastic pipe wall that can be stretched and contracted.

[0035] In this embodiment, the pipe body pressure relief expansion joint 3 is a wrinkled deformation rebound structure, and the interior of the hollow tubular thermal insulation material pipe body lumen 2 is filled with inert gas. When the thermal insulation pipe body 1 is subjected to various extrusions, deformations, and thermal expansion and contraction caused by changes in the climate, the pipe body pressure relief expansion joint 3 will generate a buffer space to offset the deformation, thereby solving the problem of the water-blocking, moisture-proof, and thermal insulation stability performance of the thermal insulation pipe body being affected by the pressure rupture of the closed hollow thermal insulation pipe lumen. When the hollow tubular thermal insulation material pipe body 1 is used for the insulation of pipelines or building materials, multiple thermal insulation pipe bodies can be tied together, and then a protective bundle 9 is provided on the outside of the thermal insulation pipe body. This setting can effectively reduce the impact on the entire device and avoid damage to the thermal insulation pipe body. When the thermal insulation pipe is used on clothing, only the thermal insulation pipe body can be used.

[0036] In this embodiment, the bundled sleeves 9 are all bundled tube-sleeve structures.
