Description

방오(오염 방지성), 발수, 방염 기능을 가지는 흡음재 {Sound-absorbing materials that have not a stain, absorb moisture and burn in light function}Sound-absorbing materials that have not a stain, absorb moisture and burn in light function}

본 고안은 방음재의 구조에 대한 고안으로서, 특히 표면에 쉽게 이물질이 묻어 오염이 되지 않는 방오성과 습기를 흡수하지 않는 발수성 및 불에 잘 타지 않는방염성을 가지는 흡음재에 대한 고안으로서, 종래에는 일반적으로 소정 두께의 다공성 스폰지 모재 표면에 공지한 방염액을 침지하여 건조한 방염 부직포를 접착제를 매개로 접합하여 방염성을 가지는 흡음재를 제조하였다.The present invention is a devise for the structure of the soundproofing material, in particular, a devise for the sound-absorbing material having a water-repellent property that does not easily absorb dirt on the surface and does not absorb moisture, and a flame retardant that does not burn well, and is generally prescribed A known flame retardant was immersed on the surface of the porous sponge base material having a thick thickness, and a dry flame retardant nonwoven fabric was bonded through an adhesive to prepare a sound-absorbing material having flame retardancy.

방염액에 침지한 부직포를 스폰지에 접합하여 방염성만을 가지는 종래의 흡음재와는 달리 오염방지와 발수성까지 겸하는 흡음재를 개발, 제조하기 위하여 방염액을 침지한 부직포에 방오, 발수제를 코팅하여 시험한 결과 이들 약품의 화학적 변화에 의하여 방오와 발수 기능은 유지되나 방염성능이 매우 저하되어 화재에 취약한 문제점이 있어 이 점을 해결해야 할 기술적 과제를 가지고 있다.Unlike conventional sound-absorbing material having only flame retardancy by bonding nonwoven fabric immersed in flame-retardant solution to sponge, it has been tested by coating antifouling and water repellent on non-woven fabric impregnated with flame retardant in order to develop and manufacture sound-absorbing material that serves both pollution prevention and water repellency. The antifouling and water repellent function is maintained by chemical change of the chemical, but the flame retardant performance is very degraded, so there is a problem that is vulnerable to fire.

도 1 은 본 고안상으로 실시구성되는 방오,발수,방염 기능을 가지는 흡음재의 일부절결사시도.Figure 1 is a partially cutaway perspective view of the sound absorbing material having an antifouling, water-repellent, flame retardant is configured according to the present invention.

도 2 는 도 1 의 단면도.2 is a cross-sectional view of FIG.

1. 흡음제 2. 다공성 스폰지 기재층1. Sound absorbing agent 2. Porous sponge base layer

3. 부직포층 4. 방오, 발수 피막층3. Non-woven fabric layer 4. Antifouling, water repellent coating layer

5. 방염 코팅 피막층5. Flameproof coating film layer

본 고안은 방오, 발수성이 우수하면서도 방염성 또한 우수한 흡음재에 대하여 안출한 고안인 바, 이를 첨부한 도면에 의거하여 상술하면 다음과 같다.The present invention is devised for the sound-absorbing material excellent in antifouling, water repellency but also excellent flame retardant, when described in detail based on the accompanying drawings as follows.

본 고안상으로 실시되는 흡음재(1) 구조는 공지한 흡음재 기재인 다공성 난연 스폰지 기재층(2)과 부직포(3)를 접합하되, 부직포(3)의 표면에 방오, 발수성을 가지도록 방오, 발수 피막층(4)을 코팅한 다음 그 배면에 방염제를 코팅하여 방염 코팅 피막층(5)을 가지도록하므로써 방오, 발수, 방염 기능을 가지도록 가공한 부직포(3)를 엠보싱 가공한 후 기재층(2)의 일면에 공지한 방법인 열가압착하여 일체로 접합하므로서 본 고안상으로 실시구성되는 흡음재(1)를 제조한다.The sound absorbing material (1) structure implemented in accordance with the present invention is bonded to the porous flame-retardant sponge base material layer 2 and the nonwoven fabric (3), which is a known sound absorbing material substrate, but the antifouling, water-repellent so as to have antifouling, water repellency on the surface of the nonwoven fabric (3) After coating the coating layer (4) and then coating the flame retardant on the back to have a flameproof coating coating layer (5) by embossing the nonwoven fabric (3) processed to have an antifouling, water-repellent, flame retardant function base material layer (2) The sound-absorbing material 1 constituted by the present invention is manufactured by thermally compressing and joining integrally, which is a known method.

상기와 같이 다공성 스폰지 기재층으로 되는 흡음재로서, 화재에 대비한 방염 성능 이외에 쉽게 오염되지 않고 오염된 후라도 쉽게 닦을 수 있는 오염 방지 효과가 있으며, 습기가 많은 장소의 흡음재 사용이 가능하도록 물이 배어들지 않는 발수 효과가 있어 내구성의 향상과 흡음재로서의 용도가 확대되고 효용가치가 상승되는 등 부수적 효과가 있다.As the sound absorbing material of the porous sponge base layer as described above, in addition to the flame retardant performance against fire, it is not easily contaminated and has a pollution prevention effect that can be easily wiped even after being contaminated. There is a water-repellent effect that does not have the secondary effect, such as improving the durability, the use of the sound absorbing material is expanded and the utility value is increased.
