Description
제1도는 본 고안의 내장재에 대한 구성단면도이다.1 is a cross-sectional view of the interior material of the present invention.
* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1,4 : 경질P.V.C 2,3 : 폴리프로필렌폼1,4 rigid P.V.C 2,3 polypropylene foam
본 고안은 자동차의 천정 등의 내장에 사용되는 차량용 내장재에 관한 것이다.The present invention relates to a vehicle interior used in the interior of the ceiling of the vehicle.
종래 열가소성 수지발포체 시트 특히 폴리올레핀계 수지로 제작된 가교발포체 시트는, 우수한 충격흡수성, 쿠션성을 가지며, 또 진공성형등의 이차가공이 용이하게 행해지도록 하기위해 여기에 표면재 등을 적층시킨것이 차량용 내장재로써 적합하게 이용되어 왔었다.The conventional thermoplastic resin foam sheet, especially the crosslinked foam sheet made of polyolefin resin, has excellent impact absorbing properties and cushioning properties, and in order to facilitate secondary processing such as vacuum molding, a surface material or the like is laminated thereon as a vehicle interior material. It has been suitably used.
그리고, 이들 열가소성 수지발포체 시트에 폴리에틸렌등의 열가소성 수지 시트를 적층하는 것으로 보강하여 그 발포시트의 강성 등을 향상시키도록 하는 것은 이미 알려져 있다(예로써, 일본특허공고 소화 제61-53257호).And it is already known to reinforce by laminating | stacking thermoplastic resin sheets, such as polyethylene, on these thermoplastic resin foam sheets to improve the rigidity etc. of this foam sheet (for example, Japanese Patent Laid-Open No. 61-53257).
이와같이, 역가소성 수지 시트를 열가소성 수지발포체 시트에 적층하는 것은, 이차가공성 등의 면에서 적절히 사용되지만, 내열성이 충분하지 못하기 때문에, 보통의 폴리에틸렌 시트등의 열가소성 수지시트를 적층한 것으로 이루어지는 자동차용 성형천정재 등은, 내열성이 좋지못하여 고온하에서는 접착력이 저하되어 떨어져 버린다는 결점이 있다.As described above, the lamination of the thermoplastic resin sheet to the thermoplastic resin foam sheet is appropriately used in terms of secondary processing properties and the like. However, since the heat resistance is not sufficient, for automobiles, the thermoplastic resin sheet such as ordinary polyethylene sheets is laminated. Molded ceiling materials and the like have a disadvantage in that the heat resistance is poor and the adhesive force is lowered and dropped at high temperatures.
따라서 상기한 문제점을 해결하기 위한 종래의 또다른 발명은 예로써, 일본 공개특허공보 소화 제63-219442호의 것이 나와있다.Therefore, another conventional invention for solving the above problems is disclosed, for example, in Japanese Patent Laid-Open No. 63-219442.
상기한 종래발명은 전술한 내열성의 문제를 해결하기위해 열가소성 수지 발포 성형체의 편면 또는 양면에 가교폴리프로필레시트 또는 필름을 적충한 것을 사용하되, 특히 가교폴리프로필렌시트 또는 필름에 유리섬유를 혼합시켜 내열성 및 강성을 향상시키도록 한 것이다.In order to solve the above-mentioned heat resistance problem, the above-mentioned conventional invention uses a crosslinked polypropylene sheet or film on one side or both sides of the thermoplastic resin foamed molded article, in particular by mixing glass fiber in the crosslinked polypropylene sheet or film. It is to improve the heat resistance and rigidity.
그러나 상기한 종래 기술은 유리섬유나 슈지펠트(재생합성섬유)를 사용하면 재질자체의 이질성문제로 인해, 적층시 적층불량이 생기며, 적층한 다음 표피의 가판예열후 프레스에 의한 성형에 있어 불량발생률이 높고 중량이 무거운 단점이 있다.However, in the above-described conventional technique, when glass fiber or susiefeld (regenerated synthetic fiber) is used, due to the heterogeneity of the material itself, lamination defects occur in lamination, and the incidence of defects in forming by pressing after lamination and preheating of the skin after lamination This has the disadvantage of high and heavy weight.
본 고안은 상기한 모든 단점들을 더욱 보완하기 위하여 안출된 것으로, 중량이 가볍고 저렴한 가격으로 제조될 수 있으며 또한 내열성 및 성형성도 우수한 차량용 내장재에 관한 것이다.The present invention is devised to supplement all the above-mentioned shortcomings, and relates to a vehicle interior material that can be manufactured at a light weight and a low price, and also has excellent heat resistance and moldability.

Made of structure.
상기한 본 고안을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.
먼저 제1도에 나타내는 바와같이 본 고안의 기재로 사용되는 폴리프로필렌 폼(2,3)은 독립가포구조를 갖는 폴리에틸렌,폴리프로필렌등의 폴리올레핀계의 발포체 또는 P.V.C발포체를 사용한다.First, as shown in FIG. 1, the polypropylene foams (2, 3) used as the base material of the present invention use polyolefin-based foams or P.V.C foams such as polyethylene and polypropylene having independent foam structures.
본 고안에서 사용되는 기재로서는, 폴리프로필렌 재질로 이루어지는 발포체로 형성시키는 것이 바람직하다.As a base material used by this invention, it is preferable to form with the foam which consists of a polypropylene material.
본 고안에 의한 폴리프로필렌 폼(2,30을 제조할 경우, 먼저, 폴리프로필렌 모판시트를 만들어 전자선조사에 의해 가교시킨후, 대기압하에서 발포시킨 시트체로써 형성시키는바, 그 발포배율을 20∼30배(특히 적합하기로는 25배)로 발포시켜 그 발포체의 밀도가 0.030∼0.058/㎤정도 되도록 하고 두께는 3∼5㎜ 갖도록 한다.Polypropylene foam according to the present invention (when manufacturing 2,30, first, a polypropylene mother sheet is formed, crosslinked by electron beam irradiation, and then formed into a sheet body foamed under atmospheric pressure, the expansion ratio of which is 20 to 30 The foam is foamed in a fold (especially 25 times suitably) so as to have a density of about 0.030 to 0.058 / cm 3 and a thickness of 3 to 5 mm.
이와같이 제조된 폴리프로필렌 폼(2,3)기재는 내열성이 뛰어나고 성형성이 매우 좋다. 또한 본 고안에 사용되는 내장재의 외피표면층은 경질 P.V.C를 사용하는데 본 경질P.V.C(1,4)는 접착제를 포함하도록 하여 폴리프로필렌 폼(2,3)의 상하면에 각각 라미네이트 한다.The polypropylene foam (2,3) base material thus prepared has excellent heat resistance and very good moldability. In addition, the outer surface layer of the interior material used in the present invention uses a hard P.V.C. The hard P.V.C (1,4) is laminated on the upper and lower surfaces of the polypropylene foam (2,3) to include an adhesive.
또한, 양표면에 접합시키는 경질 P.V.C재질의 특징은 낮은 압력하에서도 성형이 가능하고 인열강도(tear strenght)가 우수하며, 가공후의 냉각시 수축이 적고 성형시 처짐(sagging)현상의 발생도 극히 적으며 또한 접착성도 우수하므로 본 고안의 기재에 접합시키기에 매우 적합한 것이다.In addition, the characteristics of the rigid PVC material bonded to both surfaces can be formed under low pressure, excellent tear strenght, less shrinkage during cooling after processing, and extremely sagging phenomenon during molding. It is also very suitable for bonding to the substrate of the present invention because of its low adhesiveness.
또한, 경질 P.V.C를 열에 의한 열성형시 유리전이온도 이상의 넓은 온도범위에 걸쳐 단축(uniexial) 및 이축(biaxial)방향의 신장성이 우수하므로 열성형성이 좋고 열안정성도 뛰어나며 점도안정성 등도 우수한 장점이 있다.In addition, when the rigid PVC is formed by heat, it has excellent thermoformability, excellent thermal stability, and excellent viscosity stability because it has excellent extensibility in the uniexial and biaxial directions over a wide temperature range above the glass transition temperature. .
또한, 표면에 접합시키는 경질 P.V.C에는 가교성, 대전성, 또는 난연성을 갖는 다른 재료를 포함시켜 내장재가 상기한 각각의 특성을 갖도록 할 수도 있으며 또, 컬러링(coloring), 엠보싱(Embossing)등의 특성이 뛰어나도록 하기위해 상기한 특성을 갖는 별도의 재료를 포함시킬 수도 있다.In addition, the rigid PVC bonded to the surface may include other materials having crosslinkability, chargeability, or flame retardancy so that the interior material may have each of the above-described characteristics, and may also have characteristics such as coloring and embossing. In order to make this outstanding, a separate material having the above-described properties may be included.
이와같이 경질 P.V.C에 선택적으로 각종 특성을 갖는 재료들을 포함시키는 것은 내장재의 제품의 특성을 다양화시켜 본 제품이 적용되는 차량에 따라 선택의 폭을 넓게 적용시킬 수 있는 장점이 있기 때문이다.Such incorporation of materials having various properties selectively into the hard P.V.C is because the characteristics of the product of the interior material can be diversified to have a wide range of choices depending on the vehicle to which the product is applied.
그러면 상기한 본 고안의 내장재와 같은 4층 단면구조로 적층하는 방법을 공정순으로 이하 설명한다.Then, a method of laminating in a four-layered cross-sectional structure such as the interior material of the present invention described above will be described below in the order of process.
본 고안의 차량용 내장재는, 4층의 적층구조로 이루어지는바, 먼저, 제1방법으로는, 제1도에서 두장의 폴리프로필렌 폼(2,3) 한쪽면에 접착제를 도포하여 건조시킨후 열을 가하여 압착에 의해 접착시킨후, 이와같이 접착된 폴리프로필렌 폼(2,3) 상면에 경질 P.V.C(1)를 상기의 같은 방법으로 접착시키고, 마지막으로 하면에 또다른 경질 P.V.C(4)를 상기와 같은 방법으로 접착시켜 4층단면구조로 이루어진 시트체를 형성시킨다.The vehicle interior of the present invention has a laminated structure of four layers. First, in the first method, an adhesive is applied to one side of two polypropylene foams (2, 3) in FIG. After adhering by pressing, hard PVC (1) is adhered to the upper surface of the polypropylene foam (2,3) bonded in this manner in the same manner as described above, and finally, another hard PVC (4) is adhered to the lower surface as described above. It bonds by the method and forms the sheet | seat which consists of a four-layered cross-sectional structure.
또 다른 제2의 적층방법은, 먼저 경질 P.V.C(1)와 폴리프로필렌 폼(2)을 상기와 같은 방법으로 한세트 접착한후, 별도로 폴리프로필렌 폼(3)과 경질 P.V.C(4)를 또다른 세트로 접착시킨다. 그리고 이와같이 각각 접착된 세트 1쌍을 제1도와 같이 접착되도록 즉, 폴리프로필렌 폼(2)과 폴리프로필렌 폼(3)을 상호 접합시켜서 하나의 시트체로 형성시킨다.In another second lamination method, first, the rigid PVC 1 and the polypropylene foam 2 are bonded together in the same manner as described above, and then the polypropylene foam 3 and the rigid PVC 4 are separately set. To be bonded. The pair of sets bonded to each other in this manner is bonded to each other as shown in FIG. 1, that is, the polypropylene foam 2 and the polypropylene foam 3 are bonded to each other to form a sheet.
상기한 두가지의 적층방법은, 모두다 접합체와 열에 의한 압착으로 제조되는바, 이는 제조설비의 구조에 따라 상기한 제1 또는 제2방법을 선택하여 접착하면 된다.The two lamination methods described above are both manufactured by compression bonding with a joined body and heat, and this may be performed by selecting and bonding the first or second method according to the structure of the manufacturing equipment.
이와같이 적층시킨 차량용 내자재 시트는 몰드성형에 의해 각각의 형상을 갖는 차량 내장재 제품으로 제조된다.The vehicle interior material sheets thus laminated are manufactured into vehicle interior materials having respective shapes by mold molding.
이상과 같이 본 고안의 내장재 구성에 의하면, 기재로 사용되는 20∼30배 발포체인 폴리프로필렌 폼은 무게가 가벼울 뿐만아니라, 내열성과 성형성도 우수하며, 그의상하표피로 적층하는 경질 P.V.C는 가격이 저렴할 뿐만아니라 필요에 따라 다른 재료와의 혼합이 용이하여 가교성, 대전성, 난연성, 칼러링, 엠보싱 등의 특성을 갖도록 할 수 있다.As described above, according to the interior material composition of the present invention, polypropylene foam, which is a 20-30 times foam used as a substrate, is not only light in weight, but also excellent in heat resistance and moldability, and rigid PVC laminated with its upper and lower cuticles is inexpensive. In addition, if necessary, it can be easily mixed with other materials to have properties such as crosslinkability, chargeability, flame retardancy, coloring, embossing, and the like.
그리고 본 고안에 의한 표피재로써 경질 P.V.C를 사용하여 제조된 본 고안의 차량용 내장재에 의하면, 가공 온도범위가 넓어 상온가공도 가능하며 충격강도도 우수하고 가공안정성이 뛰어나다. 그리고 수축강도가 우수하며 신장율이 최대가 되는 온도에서는 매우 다양한 성형이 가능한 장점이 있다.And according to the vehicle interior material of the present invention manufactured using hard P.V.C as the skin material according to the present invention, the processing temperature range is wide, room temperature processing is also possible, excellent impact strength and excellent processing stability. In addition, the shrinkage strength is excellent, and there is an advantage that a wide variety of molding is possible at a temperature at which the elongation is maximized.
