Abstract
Description
[Technical Field]
[0001] This invention relates to a heat insulating material that is built into the back of a multi-layered aluminum vapor-deposited sheet with holes for use on the walls, floors, and attics of houses, and in the interior door ceilings of vehicles. [Background technology]
[0002] This sheet is used to keep warm in winter, insulate in summer, maintain a constant temperature in other seasons, prevent condensation, and prevent radio interference. Conventional sheet insulation materials have poor breathability and moisture dissipation, which can lead to mold and mildew growing inside the insulation material.
[0003] The present invention aims to eliminate these drawbacks, ensure breathability, and promote the dissipation of moisture and air.
[0004] Now, to explain the solution with reference to the drawings, a perforated aluminum sheet (2) (5) is embedded within the multi-layer sheet insulation, similar to the perforated aluminum sheet (2). The perforated aluminum sheet layer (2) (5) embedded between the multiple layers can be placed in any of the following layers: (1) (6) front and back layers, (3) insulation layer, and (4) durability layer. Effects of the invention
[0005] The aluminum sheets inside the multi-layer sheet are perforated, which allows for high breathability, so even if moisture enters from the outside, it evaporates quickly and does not retain moisture or humidity for long periods of time. It also reduces air retention inside the multi-layer sheet. [Brief explanation of the drawings]
[0006] [Figure 1] Cross-sectional view of the device DETAILED DESCRIPTION OF THE INVENTION
[0007] This device incorporates an aluminum sheet layer that has been perforated during the manufacturing process into one of the layers of a multi-layer sheet insulation material. [Explanation of symbols]
[0008] ▲1▼ is an aluminum vapor deposition layer on a perforated nonwoven fabric, ▲2▼ is a nonwoven fabric layer attached to the perforated backside of an aluminum vapor deposition film, ▲3▼ is a 300g / m2 layer of insulating short-spun polyester fiber, ▲4▼ is a durable polypropylene fiber layer, ▲5▼ is a nonwoven fabric layer attached to the perforated backside of an aluminum vapor deposition film, ▲6▼ is an aluminum vapor deposition layer on a perforated nonwoven fabric, and ▲3▼ and ▲4▼ are needle-punched.
Claims
[Claim 1] A multi-layered heat-shielding insulation material in which a perforated aluminum sheet is embedded in a multi-layered sheet-type insulation material and quilted, and may be bonded with a plasticizer.
