Description

자동차용 내/외장재{INTERIOR AND EXTERIOR MATERIAL FOR AUTOMOBILE}Interior/exterior materials for automobiles {INTERIOR AND EXTERIOR MATERIAL FOR AUTOMOBILE}

본 발명은 자동차용 내/외장재에 관한 것으로서, 상세하게는 본체의 발포성형을 위한 폴리우레탄의 사용량을 최소화하면서 폴리우레탄 부족으로 인한 상부글라스매트와 골판지의 접합불량을 없애줄 수 있도록 한 것이다.The present invention relates to an interior/exterior material for automobiles, and specifically, to minimize the amount of polyurethane used for foam molding of the main body, and to eliminate the poor bonding between the upper glass mat and the corrugated cardboard due to lack of polyurethane.

일반적으로 자동차 내부는 러기지보드(Luggage Board)와 시트백(Sit Back), 언더커버(Under Cover), 필러(Piller), 선바이저(Sun Visor), 선쉐이드 플레이트(Sunshade plate), 커버링 쉘프(Covering Shelf) 및 매트 어셈블리 러기지 커버(Mat Assembly Luggage Cover) 등과 같은 각종 내/외장재로 마감해 주도록 하고 있다.In general, the interior of a car is a luggage board, seat back, under cover, filler, sun visor, sunshade plate, and covering shelf. Shelf) and mat assembly luggage cover (Mat Assembly Luggage Cover) to finish with various interior/exterior materials.

이러한 자동차용 내/외장재들은 자동차부품이 갖는 특성상 경량화와 치수안정성 및 기능별 적절한 강도 등이 요구된다.These interior/exterior materials for automobiles require weight reduction, dimensional stability, and appropriate strength for each function due to the characteristics of automobile parts.

이에 경량화를 위한 허니컴 상하에 휨강도보강을 위한 글라스매트를 결합하여 폴리우레탄을 이용한 발포성형으로 본체를 얻은 다음 본체 상하에 표면재와 이면재를 접합형성하여 제품화해 주도록 한 자동차용 내/외장재에 대하여 이미 등록특허 10-0493758호 '자동차 선루프용 커버'와 등록특허 10-0592681호 '자동차 선루프의 선쉐이드 및 그 제조방법' 및 등록특허 10-1705628호 '자동차 트렁크보드 및 그 제조방법' 등을 제공한바 있다.Therefore, the interior/exterior materials for automobiles are already registered by bonding the glass mats for flexural strength reinforcement at the top and bottom of the honeycomb for weight reduction to obtain the body by foam molding using polyurethane, and then bonding the surface material and the back material on the top and bottom of the body to make a product. Providing Patent No. 10-0493758'Car sunroof cover', Registration Patent No. 10-0592681'Sunshade of car sunroof and its manufacturing method', and Patent No. 10-1705628'Car trunk board and its manufacturing method' I have one.

그러나 상기한 자동차용 내/외장재들의 경우 경량화를 위한 허니컴의 각 공간부가 상하로 관통형성되고 또 상기 허니컴 상하에 휨강도보강을 위하여 결합되는 글라스매트는 매우 성글어 본체의 발포성형을 위하여 상하글라스매트의 외측으로부터 점액성의 폴리우레탄을 공급할시 상부글라스매트를 통하여 공급되는 폴리우레탄은 자중에 의해 곧바로 상부글라스매트를 통과하여 허니컴이 갖는 각 공간부 내부로 신속하게 침투하게 된다.However, in the case of the interior/exterior materials for automobiles described above, each space part of the honeycomb for weight reduction is formed vertically, and the glass mat that is joined to reinforce the flexural strength above and below the honeycomb is very sparse, so that the upper and lower glass mats are used for foam molding. When supplying viscous polyurethane from the outside, the polyurethane supplied through the upper glass mat immediately passes through the upper glass mat by its own weight and quickly penetrates into each space of the honeycomb.

따라서 재료비 절감 및 경량화 등을 이유로 상부글라스매트를 통하여 공급되는 폴리우레탄의 공급량을 줄일 경우 상부글라스매트는 폴리우레탄 부족으로 인하여 허니컴과의 접합이 제대로 이루어질 수가 없어 불량제품을 양산하게 되고, 이와 반대로 허니컴의 각 공간부를 가득 채울 만큼 폴리우레탄의 공급량을 늘려줄 경우 재료비상승으로 이어져 제품의 가격경쟁력이 떨어지게 됨은 물론 중량증가로 인하여 차량의 연비개선에 일조할 수가 없게 되는 등의 문제점들이 있는 것이다.Therefore, if the supply of polyurethane supplied through the upper glass mat is reduced for reasons such as material cost reduction and weight reduction, the upper glass mat cannot be properly bonded to the honeycomb due to lack of polyurethane, resulting in mass production of defective products. If the supply of polyurethane is increased enough to fill each space of the vehicle, it leads to an increase in material costs, which leads to a decrease in the price competitiveness of the product, as well as the inability to contribute to improving the fuel efficiency of the vehicle due to the increase in weight.

본 발명의 목적은 원하는 강도를 지닐 수 있도록 하면서 본체의 발포성형을 위한 폴리우레탄의 사용량을 최소화 할 수가 있고 또 상부글라스매트와 골판지의 접합이 견고하게 이루어지도록 할 수가 있는 자동차용 내/외장재를 제공하는데 있다.An object of the present invention is to provide an interior/exterior material for automobiles capable of minimizing the amount of polyurethane used for foam molding of the main body while maintaining the desired strength, and making the bonding between the upper glass mat and the corrugated board firmly achieved. There is.

Corrugated cardboard used forms an inflow hole in the cardboard that is adhered to the top or bottom of the corrugated board, so that the inflow hole delays the penetration rate of polyurethane into the cardboard, minimizing the amount of polyurethane used, and is sufficient for bonding with the cardboard on the upper glass mat. It is characterized in that it is constructed so that a quantity of polyurethane can remain.

본 발명은 자동차용 내/외장재(10)로서 요구되는 충분한 강도를 지닐 수 있도록 하면서 본체(22)의 발포성형을 위한 폴리우레탄(18)(20)의 사용량을 최소화할 수가 있어 재료비절감으로 제품의 가격경쟁력을 높여줄 수 있고 또 제품의 경량화로 차량의 연비개선에 일조할 수 있으며, 폴리우레탄(18) 부족에 의한 상부글라스매트(14)와 골판지(12)의 접합불량을 방지해 줄 수 있게 되는 등의 효과가 있는 것이다.The present invention is capable of minimizing the amount of use of polyurethane 18 and 20 for foam molding of the main body 22 while ensuring sufficient strength required as the interior/exterior material 10 for automobiles. It can increase price competitiveness and contribute to improving the fuel economy of the vehicle by reducing the weight of the product, and to prevent poor bonding between the upper glass mat 14 and the corrugated cardboard 12 due to the lack of polyurethane 18. It has an effect such as becoming.

도 9는 본 발명에 이용되는 골판지의 다른실시예를 보여주는 사시도이고, 도 10은 본 발명에 이용되는 골판지의 다른실시예를 보여주는 분해사시도이며, 도 11은 본 발명의 다른실시예를 보여주는 단면구성도로서, 본 발명에서 본체(22)의 발포성형 시 이용되는 골판지(12)는 골심지(32)의 상하면에 판지(34)(40)를 접착형성하고 또 상하판지(34)(40)에는 각각 골심지(32)의 상하공간부(36)(42)를 관통하는 직경이 작은 유입공(38)(44)을 촘촘히 형성하여 본체(22)의 발포성형을 위하여 상하글라스매트(14)(16) 외측으로부터 폴리우레탄(18)(20)을 공급할 시 하부폴리우레탄(20) 역시 하부판지(40)가 갖는 유입공(44)이 골심지(32)의 하부공간부(42)에 대한 침투속도를 지연시켜서 하부공간부(42) 내에도 골판지(12)의 강도보강 및 본체(22)의 발포성형 시 필요로 하는 최소량의 폴리우레탄(18)을 침투시켜줄 수 있도록 한다.Figure 9 is a perspective view showing another embodiment of the cardboard used in the present invention, Figure 10 is an exploded perspective view showing another embodiment of the cardboard used in the present invention, Figure 11 is a cross-sectional configuration showing another embodiment of the present invention As a figure, in the present invention, the corrugated board 12 used in the foam molding of the main body 22 is formed by bonding cardboard 34 and 40 to the upper and lower surfaces of the corrugated board 32, and the upper and lower cardboards 34 and 40, respectively The upper and lower glass mats (14) (16) for foam molding of the main body (22) by forming inlet holes (38) (44) with small diameters penetrating the upper and lower spaces (36) (42) of the golsimji (32) When the polyurethane (18) (20) is supplied from the outside, the inlet hole (44) of the lower cardboard (40) also delays the penetration rate into the lower space (42) of the corrugation (32). Thus, it is possible to infiltrate the minimum amount of polyurethane 18 required for reinforcing the strength of the corrugated cardboard 12 and foaming the main body 22 into the lower space 42.

따라서 본 발명은 본체(22)의 발포성형을 위한 폴리우레탄(18)(20)의 공급시 골판지(12)의 판지(34)(40)가 갖는 유입공(38)(44)이 골심지(32)가 갖는 공간부(36)(42)에 대한 침투속도를 지연시켜주게 되므로 재료의 낭비를 없애줄 수가 있고 또 제품을 더욱 경량화할 수가 있게 된다.Therefore, in the present invention, when supplying the polyurethane (18) (20) for foam molding of the main body (22), the inlet holes (38) (44) of the cardboard (34) (40) of the corrugated board (12) are ) Delays the penetration speed into the spaces 36 and 42, thus eliminating wasted material and further reducing the weight of the product.

특히 상부글라스매트(14) 외측으로부터 공급되어 자중에 의해 상부판지(34)가 갖는 유입공(38)을 통하여 골판지(12)의 상부공간부(36) 내부로 침투한 폴리우레탄(18)은 본체(22)의 발포성형 시 각기 골판지(12)의 골심지(32)가 갖는 상부공간부(36) 내에서 상부판지(34)를 지지하는 기둥역할을 하게 되므로 폴리우레탄(18)의 사용량을 최소화하면서 골판지(12) 및 본체(22)의 강도를 강화시켜줄 수가 있고 또 상부글라스매트(14)에는 충분한 량의 폴리우레탄(18)을 잔류시켜서 상부글라스매트(14)와 골판지(12)의 접합이 견고하게 이루어지도록 할 수가 있게 된다.In particular, the polyurethane 18 supplied from the outside of the upper glass mat 14 and penetrated into the upper space 36 of the corrugated cardboard 12 through the inlet hole 38 of the upper cardboard 34 by its own weight 22), the corrugated cardboard (12) serves as a pillar to support the upper cardboard (34) within the upper space (36) of the corrugated cardboard (12), thereby minimizing the amount of polyurethane (18). 12) and the strength of the main body 22 can be reinforced, and a sufficient amount of polyurethane 18 remains in the upper glass mat 14, so that the upper glass mat 14 and the corrugated cardboard 12 are bonded firmly. You will be able to lose.
