본 발명은 방풍부재용 연질필름 조성물과, 연질필름을 이용한 방풍부재에 관한 것으로, 보다 상세하게는 모헤어에 연질필름을 일체로 설치하여 우수한 방풍효과와 함께 사용중 필름이 찢어지지 않도록 하면서, 방풍부재 성형이 용이하도록 하는 방풍부재용 연질필름 조성물과, 연질필름을 이용한 방풍부재에 관한 것이다.The present invention relates to a flexible film composition for a windshield member and a windshield member using the flexible film. More particularly, the present invention relates to a windshield member comprising a flexible film formed integrally with a mohair, And a windshield member using the soft film.

일반적으로 미닫이식 또는 여닫이식의 도어나 창문 사이에는 소정의 틈이 형성되며, 이러한 틈은 외부로부터 바람, 소음 등이 내부로 침투 또는 전달되는 통로가 되어 실내가 안락한 환경을 가질 수 없게 되므로, 바람 등이 실내로 들어오는 것을 방지하기 위하여 상기 틈에는 통상 방풍 부재가 부착되어 사용되고 있다.Generally, a predetermined gap is formed between a sliding door or a hinged door or a window. Such a gap is a passage through which wind, noise, etc. are penetrated or transmitted from the outside, and the room can not have a comfortable environment. And the like are usually used with the windshield members attached thereto to prevent them from entering the room.

이러한 방풍 부재의 예로는, 첫째는 폼형태로 형성된 것이고, 둘째는 산양 등의 동물의 털을 가공처리하거나 합성섬유사를 소정폭을 갖는 띠지상에 식모한 모헤어이며, 셋째로는 플라스틱수지로 압출성형된 프레임형태로, 도어(문)에 부착되는 부분은 경질로, 도어프레임에 접하는 부분은 연질로 이중 압출성형된 것이 있으며, 이들 세가지를 단독으로 혹은 혼합하여 사용되기도 한다.An example of such a windshield member is a foam formed in the form of a foam, an animal such as an animal such as a goat, or a synthetic fiber knitted mohair on a belt having a predetermined width. Third, In the form of a molded frame, the portion attached to the door (door) is rigid, and the portion in contact with the door frame is soft and extruded, and these three may be used singly or in combination.

이러한 방풍부재는 통상 일면에 접착제와 이형지가 구비되어 사용하고자 하는 틈새에 이형지를 제거하고 접착제로 접착하여 사용하였으며, 혼합하여 사용하는경우 공개특허 10-2009-0037736호 나타내는 바와 같이 통상 압출성형된 프레임에 상기 폼형태 또는 모헤어가 부착되는 공간이 형성되어 해당 공간으로 폼 또는 모헤어를 부착하여 사용하였다.Such a windshield member is generally provided with an adhesive agent and a release paper on one surface thereof, and the release paper is removed from the gap to be used and adhered with an adhesive. In the case of using the windshield element as a mixture, A foam or a mohair is adhered to the space and the foam or mohair is attached to the space.

이러한 방풍부재 중 모헤어의 경우에는 띠지상에 합성섬유사를 식모한 것으로 합성섬유사 사이로 틈이 발생되어 방풍효과가 감소되므로 합성섬유사사이에 부직포, 필름 등을 더 삽입한 기술들이 공개되어 있으며, 상기 공개특허 10-2009-0037736호에서는 필름이 부착된 기술이 공개되어 있다.In the case of mohair of such a windshield member, since synthetic fiber yarn is formed on the belt, a gap is formed between the synthetic fiber yarns and the windshield effect is reduced. Thus, techniques in which a nonwoven fabric, In the patent document 10-2009-0037736, a technique in which a film is attached is disclosed.

그러나, 종래 모헤어를 구성하는 띠지 및 합성섬유사는 모두 폴리프로필렌(PP)으로 이루어져 있고, 이러한 모헤어와 초음파등을 통한 부착을 위해서는 동질의 PP필름을 사용하여야 하나 상기 PP 필름은 경질로서 도 1 및 도 2에 나타내는 바와 같이 틈새에 설치하는 과정 및 사용하는 과정에서 마찰로 인하여 필름이 찢어지는 경우가 빈번하게 발생되어, 설치작업이 번거로울 뿐 아니라 찢어지는 경우에는 찢어진 틈으로 바람이 통과하면서 소음이 발생하는 등의 문제점이 있었다. 또한, 상기한 경질의 경우 찢어지지 않더라도 문틈과 긴밀하게 밀착하지 못하여 틈이 발생되고 그 사이로 바람이 통과하면서 소음발생의 원인이 되었다.However, conventionally, both the belt and the synthetic fiber yarn constituting the mohair are made of polypropylene (PP), and a homogeneous PP film should be used for attachment through such mohair and ultrasonic waves. However, As shown in FIG. 2, when the film is torn due to friction during the installation process and during the process of using, the installation work is troublesome. In addition, when the film is torn, the wind passes through the tear gap, And the like. In addition, in the case of the above-mentioned hardness, even if it is not torn, it can not come into close contact with the gap of the door, so that a gap is generated, and the wind passes through it to cause noise.

이러한 문제점을 해결하기 위하여 연질의 PVC필름을 사용하고자 할 경우 모헤어를 구성하는 PP와 재질이 상이하여 접착이 원활하지 않은 문제점이 있었다.In order to solve this problem, when a soft PVC film is used, there is a problem that the material constituting the mohair is different from that of the material, so that the adhesion is not smooth.

아울러, 상기한 프레임에 모헤어(20)를 부착하는 경우 창문프레임과의 밀착력을 위하여 프레임은 도 3에 도시한 바와 같이 경질부분(30a)과 연질부분(30b)을 이중으로 압출하여야, 상기 연질부분(30b)이 창문프레임에 밀착되어 바람이 통하지 않기 때문에 프레임의 성형이 복잡한 문제점이 있었다.In addition, when the mohair 20 is attached to the frame, the rigid portion 30a and the soft portion 30b must be extruded in a double manner as shown in FIG. 3 for the purpose of adhering the mohair 20 to the window frame. Since the window 30b is in close contact with the window frame and the wind does not pass through it, molding of the frame is complicated.

이에 따라 본 발명의 목적은, 종래 PP재질로 구성된 모헤어에 부착가능한 연질소재 조성물을 제공하고, 이를 이용하여 연질필름이 부착된 방풍부재를 제공함으로서, 유연성에 의하여 설치시 찢어지는 등의 손상이 발생되지 않도록 하면서, 문틀에 밀착되어 바람이 통과하지 않도록 함으로서 완벽한 방풍효과를 얻을 수 있고 소음발생이 억제되며, 플라스틱프레임에 모헤어를 부착하는 경우 상기 연질필름이 플라스틱프레임의 연질부분을 대체함으로서 플라스틱프레임을 경질과 연질의 이중압출하지 않아도 되도록 하는 연질필름을 이용한 방풍부재를 제공하는 데 있다.Accordingly, it is an object of the present invention to provide a flexible material composition capable of attaching to a mohair which is made of a conventional PP material, and using the same to provide a windshield with a flexible film, damage such as tearing The soft film is prevented from passing through the door frame and the wind is prevented from passing therethrough. In addition, when the mohair is attached to the plastic frame, the soft film replaces the soft portion of the plastic frame, And it is an object of the present invention to provide a windshield member using a soft film which does not need to be extruded in a hard and soft manner.

상기한 목적을 달성하기 위한 본 발명의 특징은, 메탈로센 폴리프로필렌 50-80중량%와, 터폴리머 20-50중량%를 포함하여 구성되는 방풍부재용 연질필름 조성물에 있다.In order to accomplish the above object, the present invention is characterized in that the soft film composition for a windshield member comprises 50-80 wt% of metallocene polypropylene and 20-50 wt% of terpolymer.

그리고, 상기한 조성물로 이루어진 연질필름을 모헤어의 합성수지사 일측 혹은 사이에 접착한 것을 특징으로 하는 연질필름을 이용한 방풍부재에 있다.Further, the present invention is a windshield member using a soft film, characterized in that the soft film made of the composition described above is bonded to one side or between the synthetic resin side of the mohair.

그리고, 상기 연질필름이 부착된 모헤어는 'L'형 경질의 플라스틱수지의 하부면에 부착되어 사용되는 것을 특징으로 하여 별도의 연질 플라스틱수지 압출과정이 생략되도록 한다.In addition, the mohair with the soft film attached thereto is attached to the lower surface of the 'L' type hard plastic resin so that a separate soft plastic resin extrusion process is omitted.

상기한 바와 같이 구성된 본 발명에 의하면, 종래 PP재질로 구성된 모헤어에 부착가능한 연질소재 조성물을 제공함으로서, 연질필름이 부착된 방풍부재를 제공할 수 있게 되고, 이로 인하여 연질필름의 유연성에 의하여 설치 및 사용시 찢어지는 등의 손상이 발생되지 않고 문틀에 밀착되어 바람이 통과하지 않도록 함으로서 완벽한 방풍효과를 얻을 수 있고 소음이 발생하지 않게 되는 효과가 있다.According to the present invention constructed as described above, it is possible to provide a windshield with a flexible film by providing a flexible material composition that can be attached to a mohair, which is made of a conventional PP material. As a result, It is possible to obtain a perfect windproof effect by preventing wind from being passed through the door frame without causing damage such as tearing, and noise is not generated.

또한, 플라스틱프레임에 모헤어를 부착하는 경우 상기 연질필름이 플라스틱프레임의 연질부분을 대체함으로서 플라스틱프레임을 경질과 연질의 이중압출하지 않아도 되므로 생산성이 향상되는 효과가 있다.Further, when the mohair is attached to the plastic frame, the soft film replaces the soft portion of the plastic frame, so that the plastic frame is not required to be hard and soft double-extruded.

이하 본 발명의 실시예를 첨부한 도면을 참조하여 살펴본다.
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

본 발명에 따른 방풍부재용 연질필름 조성물은, 메탈로센 폴리프로필렌(metallocene-PP) 50-80중량%와, 터폴리머(terpolymer) 20-50중량%를 포함하여 구성되며, 투명색이 아니라 흰색을 원할경우에는 이산화티타늄(TiO2)을 상기 조성물 총 중량기준 1-15중량% 더 첨가한다.The flexible film composition for windshield members according to the present invention comprises 50 to 80% by weight of metallocene-PP and 20 to 50% by weight of a terpolymer, If desired, titanium dioxide (TiO 2 ) is added in an amount of 1-15% by weight based on the total weight of the composition.

상기에서 메탈로센 PP는 좁은 분자량 분포와 균일한 공단량체 분포로 인해 전통적인 지글러-나타 PP와 달리 균일한 특성을 가지고 있고, 이러한 좁은 분자량 분포 덕분에 유해한 휘발성 물질이 발생하는, 고분자 사슬을 끊는 추가 공정 없이도 고속방사를 할 수 있는 특징이 있고, 균일한 공단량체 분포 때문에 폴리카보네이트에 가까운 투명성을 보이면서도 가공성 및 물리적 특성이 좋아 생산성이 우수한 재료이다.Metallocene PP has a uniform molecular weight distribution and homogeneous comonomer distribution, unlike the traditional Ziegler-Natta PP, and this narrow molecular weight distribution leads to the addition of a broken polymer chain, which causes harmful volatiles. It is characterized by its ability to emit high-speed radiation without any process. Due to its uniform distribution of comonomers, it exhibits transparency close to that of polycarbonate, and is excellent in productivity and good physical properties.

그리고, 상기 터폴리머가 20중량%이하로 사용될 경우 경도가 너무 낮아서 설치시 창틀과 견고하게 밀착할 수 없게 되고, 터폴리머가 50중량%이상 사용될 경우 너무 경도가 높아서 설치 또는 사용중 찢어짐이 발생하고 창틀에 견고하게밀착되지 않고 틈이 발생되는는 등의 문제점이 있었다.
When the terpolymer is used in an amount of 20 wt% or less, the hardness is too low to firmly adhere to the window frame at the time of installation. When the terpolymer is used in an amount of 50 wt% or more, too high hardness results in tearing during installation or use, And there is a problem that a gap is generated.

이에 따라 본 발명의 실시예에서는 메탈로센 폴리프로필렌(상품명 VISTAMAXX) 60중량%와, 터폴리머 40중량%를 혼합한 조성물을 이용하여 필름을 성형하였으며, 이 과정에서 필름은 두께 0.2 내지 0.5mm로하여 설치시 충분한 강도와 지지력을 갖도록 한다.
Accordingly, in the embodiment of the present invention, a film is formed using a composition obtained by mixing 60% by weight of metallocene polypropylene (trade name VISTAMAXX) and 40% by weight of a terpolymer. In this process, the film has a thickness of 0.2 to 0.5 mm So that it has sufficient strength and bearing capacity when installed.

이렇게 제조된 연질필름은 PP재질의 모헤어에 융착되고, 융착은 공지의 부직포 또는 종래 경질 pp필름 융착과 동일하게 초음파융착을 이용하여 결합하게 된다.The thus-produced soft film is fused to the mohair of the PP material, and fusion bonding is performed using ultrasonic welding in the same manner as the known nonwoven fabric or conventional hard PP film fusion.

이때 본 발명의 필름과 모헤어는 모두 PP재질을 포함하고 있어서 융착과정에서 반발력이 발생하지 않아 견고하고 용이하게 접착이 가능하게 된다.
At this time, since both the film and the mohair of the present invention include the PP material, the repulsive force is not generated in the fusion process, so that the film and the mohair can be firmly and easily bonded.

그리고, 상기 연질필름(10)이 부착된 모헤어(20)는 도 4에 나타내는 바와 같이 'L'형 경질 플라스틱수지로 구성된 프레임(30)의 하부면에 부착되어 다른 형태의 방풍부재를 형성하게되는데, 이 과정에서 상기 연질필름이 종래 연질 플라스틱수지의 역할을 하게 되므로, 종래와 같이 플라스틱 프레임을 형성하는 과정에서 경질과 연질의 이중 압출과정을 수행하지 않아도 된다.
4, the mohair 20 to which the soft film 10 is attached is attached to the lower surface of the frame 30 made of 'L' type hard plastic resin to form another type of windshield member In this process, since the soft film serves as a conventional soft plastic resin, the hard and soft double extrusion process may not be performed in the process of forming the plastic frame.

이와 같이 구성된 본 발명의 연질필름(10)은 도 5에 나타내는 바와 같이 모헤어(20)에 설치되어 창문등에 설치시 자체 탄성력과 강도로 인하여 문틀에 견고하게 밀착되면서 찢어짐이 발생하지 않고, 아울러 상기 연질필름은 탄성력등에 의하여 0.2 내지 0.5mm정도의 두께로 성형이 가능하게 되므로 두께감으로 인한 방풍효과와 강도향상 등이 가능하게 된다.5, the soft film 10 of the present invention is installed on the mohair 20 and is firmly attached to the door frame due to its own elasticity and strength when installed on a window or the like, so that the soft film 10 is not torn, Since the film can be formed into a thickness of about 0.2 to 0.5 mm by elastic force or the like, it is possible to improve the wind resistance and the strength due to the thickness feeling.
