Title (EN) WATERPROOF VENTILATION SHEET AND MANUFACTURING METHOD THEREFOR
(FR) FEUILLE DE VENTILATION ÉTANCHE À L'EAU ET PROCÉDÉ DE FABRICATION ASSOCIÉ
(KO) 방수성 통기 시트 및 이의 제조 방법
Abstract:
(EN) The present invention relates to a waterproof ventilation sheet and a manufacturing method therefor, and the waterproof ventilation sheet comprises a nanomembrane, in which nanofibers are integrated in a non-woven fabric form including a plurality of pores, the waterproof ventilation sheet has a waterproof property against water pressure without leaking for 30 minutes or more under a water pressure of 1.5 m or more at a room temperature (20°C ± 5°C), and a sound transmission loss is less than 10 dB at 1000 Hz. The waterproof ventilation sheet controls a fine structure of a nanomembrane or orientation of a nanofiber so as to suppress absorption and diffused reflection of sound and to lower a sound absorption coefficient, improves waterproof, dustproof, and antifouling performance by forming a water repellent coating layer in the nanomembrane, resolves sound distortion by lowering a sound transmission loss measurement value, improves more a waterproof property by further including water repellent and oil repellent additives, and improves resistance to water pressure by improving the modulus of elasticity and strength of the nanomembrane and having great resistance to pressure strain caused by applied water pressure during resistance to water pressure.
(FR) La présente invention concerne une feuille de ventilation étanche à l'eau et un procédé de fabrication associé. La feuille de ventilation étanche à l'eau comprend une nanomembrane, dans laquelle des nanofibres sont intégrées dans une forme de tissu non tissé comportant une pluralité de pores, la feuille de ventilation étanche à l'eau possède une propriété d'étanchéité à l'eau vis-à-vis de la pression d'eau sans fuite pendant au moins 30 minutes sous une pression d'eau d'au moins 1,5 m à une température ambiante (20 °C ± 5 °C), et une perte de transmission sonore est inférieure à 10 dB à 1000 Hz. La feuille de ventilation étanche à l'eau commande une structure fine d'une nanomembrane ou une orientation d'une nanofibre, de façon à supprimer l'absorption et la réflexion diffuse du son et à abaisser un coefficient d'absorption sonore, améliore l'efficacité d'étanchéité à l'eau, d'étanchéité à la poussière et antisalissure en formant une couche de revêtement hydrofuge dans la nanomembrane, résout la distorsion sonore en abaissant une valeur de mesure de perte de transmission sonore, améliore davantage une propriété d'étanchéité à l'eau en comportant en outre des additifs hydrofuges et oléofuges, et améliore la résistance à la pression d'eau en améliorant le module d'élasticité et la résistance de la nanomembrane et en possédant une résistance élevée à la contrainte de pression provoquée par l'application d'une pression d'eau pendant la résistance à la pression d'eau.
(KO) 본 발명은 방수성 통기 시트 및 이의 제조 방법에 관한 것으로서, 상기 방수성 통기 시트는 나노 섬유들이 다수의 기공을 포함하는 부직포 형태로 집적된 나노 멤브레인을 포함하며, 상기 방수성 통기 시트는 상온(20 ℃ ± 5 ℃)에서 1.5 m 이상의 수압에서 30 분 이상 누수되지 않는 수압 방수성을 가지고, 음향 투과 손실은 1000 Hz에서 10 dB 미만이다. 상기 방수성 통기 시트는 나노 멤브레인의 미세 구조 또는 나노 섬유의 배향성을 제어하여 음의 흡수와 난반사를 억제하고 흡음 계수를 낮추며, 나노 멤브레인에 발수성 코팅층을 형성하여 방수, 방진 및 방오 성능을 향상시키고, 음향 투과 손실 측정값을 낮춤으로써 음향의 왜곡이 해소되며, 발수발유 첨가제를 더 포함함으로써 방수성이 더욱 향상되고, 나노 멤브레인의 탄성률과 강도를 개선하여 내수압시 인가되는 수압에 의한 압력 변형에 대한 저항성이 커져 내수압이 향상된 방수성 통기 시트를 제공하는 것이다.
