Description

자동차용 선루프의 선쉐이드 제조방법{MANUFACTURING METHOD OF SUNSHADE FOR AUTOMOBILE SUNROOF}MANUFACTURING METHOD OF SUNSHADE FOR AUTOMOBILE SUNROOF}

본 발명은 자동차용 선루프의 선쉐이드 제조방법에 관한 것으로서, 상세하게는 선쉐이드로서 요구되는 충분한 강도를 지니도록 하면서 재료비 절감 및 경량화할 수 있도록 한 것이다.The present invention relates to a sunshade manufacturing method of a sunroof for automobiles, and in particular, to reduce the material cost and light weight while having a sufficient strength required as a sunshade.

자동차용 선루프의 선쉐이드는 투명한 선루프글라스 아래에 개폐가능케 설치되어 선루프글라스를 통하여 차량의 내부로 침투하는 직사광선의 차단과 단열 및 흡음등의 기능을 수행하는 것으로서, 이러한 자동차용 선루프의 선쉐이드에 대하여는 이미 특허 제704340호등 여러건을 제공한바 있다.The sunshade of the automotive sunroof is installed to be opened and closed under the transparent sunroof glass to perform the functions of blocking the direct sunlight penetrating into the interior of the vehicle through the sunroof glass, insulation and sound absorption. Sunshade has already provided a number of patents including Patent No. 704340.

상기 특허 제704340호는 폴리에스터 피막층을 갖는 이면재에 발포수지를 분사한후 촙매트와 기반재인 폴리우레탄필터 및 촙매트를 차례로 중합하고, 중합체 상으로부터 발포수지액을 재분사한후 폴리에스터 피막층을 갖는 표면재를 중합한 다음 열가압 성형하여 2차에 걸쳐 분사된 발포수지액이 기반재인 폴리우레탄필터 내에 깊숙히 침투한 상태에서 발포가 이루어져 가볍고 또 휨강도가 강한 선쉐이드를 얻도록 하고 있다.Patent No. 704340 discloses spraying a foamed resin onto a backing material having a polyester coating layer and then polymerizing the matting mat, a polyurethane filter and a matting mat as a base material, and re-injecting the foaming resin solution from the polymer phase, thereby forming a polyester coating layer. The surface material is polymerized and then thermally press-molded so that the foamed resin solution sprayed in the second stage is foamed in a state deeply penetrated into the polyurethane filter, which is a base material, so as to obtain a sunshade having a light and strong bending strength.

그러나 기반재로 이용되는 폴리우레탄필터는 약12~18kg/㎥ 밀도의 다공성을 갖는 것으로서, 그 자체로서는 휨강도를 거의 기대할 수가 없기 때문에 내부에 침투되는 발포수지와 어울어져 기반재로서의 휨강도를 만족하도록 함으로서, 성형시 많은 량의 발포수지를 필요로 하게 되고 또 발포수지액은 다공성의 폴리우레탄필터가 거의 흡수하게 됨에 따라 발포수지에 의한 매끈한 표면은 기대할 수가 없어 매끈한 표면유지를 위하여 각각 폴리에스터 피막층을 갖는 표면재와 이면재가 추가사용되므로 재료비가 많이 소요된다.However, the polyurethane filter used as the base material has a porosity of about 12 to 18 kg / m 3, and since it can hardly expect the bending strength by itself, it satisfies the bending strength as the base material by matching with the foamed resin penetrating therein. As the molding requires a large amount of foamed resin and the foamed resin liquid is almost absorbed by the porous polyurethane filter, a smooth surface cannot be expected due to the foamed resin, and each has a polyester coating layer to maintain a smooth surface. And additional materials are used, so material costs are high.

또한 발포수지액이 폴리우레탄필터 내에 충분하고도 고르게 침투되게 하기 위하여는 긴 시간을 필요로 하고 또 폴리우레탄필터와 상하촙매트 외에 표면재와 이면재를 더 필요로 함에 따라 제조공정이 늘어나 작업능률이 저하됨은 물론 이러한 재료비증가 및 늘어난 제조공정등으로 인하여 현저한 생산성 저하를 가져오게 된다.In addition, it requires a long time for the foamed resin liquid to sufficiently and evenly penetrate the polyurethane filter, and in addition to the polyurethane filter and the upper and lower mats, the surface material and the backing material are needed, which increases the manufacturing process and decreases work efficiency. Of course, such an increase in material costs and increased manufacturing process will result in a significant decrease in productivity.

또한 폴리우레탄필터의 밀도가 낮은만큼 많은 량의 발포수지액이 이용되고 또 여기에 표면재와 이면재의 무게가 더해지게 됨에 따라 제품의 무게증가를 가져와 경량화를 만족시켜 줄 수가 없고 또 기반재인 밀도가 낮은 폴리우레탄필터로 인하여 선쉐이드로서 요구되는 충분한 휨강도를 지닐 수가 없게 된다.In addition, as the polyurethane filter has a low density, a large amount of foamed resin solution is used, and as the weight of the surface material and the backing material is added thereto, the weight of the product can be increased to satisfy the weight reduction, and the base material is low in density. Polyurethane filters do not have sufficient flexural strength required as sunshades.

더나아가 발포성형후에는 그 이면, 즉 실내측면에 내장재를 접착형성해 주어야만 완성된 형태를 얻게 되는데, 이제껏 내장재를 양면테이프나 또는 바인더등으로 접착형성해 주도록 함으로서 내장재의 접착시에도 작업인력과 시간이 많이 소요되므로 생산성은 더욱 저하되는등의 많은 결점들이 있는 것이다.Furthermore, after foam molding, the interior material must be adhesively formed on the back side, that is, the interior side, so that a completed form can be obtained. There are many shortcomings, such as lower productivity because it is required.

본 발명은 발포수지액의 필요량을 줄여줄 수가 있게 됨은 물론 표면재와 이면재 없이도 매끈한 표면을 갖도록 할 수가 있어 재료비를 절감할 수가 있고 또 발포수지액의 침투시간 단축 및 표면재와 이면재를 없애주는데 따른 제조공정단축으로 생산성 향상을 기대할 수가 있고, 발포수지액의 사용량 감소에 따른 경량화 및 기반재를 통한 강도보강으로 휨강도를 강화시켜 줄 수가 있으며, 더 나아가 성형후 내장재의 접착작업까지도 적은 작업인력으로 신속하게 이루어지도록 할 수가 있는 자동차용 선루프의 선쉐이드 제조방법을 제공하는데 그 목적이 있다.The present invention can reduce the required amount of the foamed resin solution as well as to have a smooth surface without the surface material and the backing material can reduce the material cost, and also to reduce the infiltration time of the foamed resin liquid and to eliminate the surface material and the backing material Productivity can be expected to be shortened, and it is possible to reinforce the flexural strength by reducing the amount of foamed resin solution and strengthening the strength through the base material. It is an object of the present invention to provide a method for manufacturing a sunshade of an automotive sunroof that can be made.

본 발명의 목적은 발포수지액이 분사된 촙매트 상에 높은 폴리우레탄필터와 촙매트를 차례로 중합하여 그 중합체 상부로부터 발포수지액을 분사한후 열가압성형하고, 성형후에는 그 이면에 핫멜트필름이 접착된 내장재를 겹쳐서 가열가압에 의해 접착형성해 주도록 한 자동차용 선루프의 선쉐이드 제조방법에 의해 달성된다.An object of the present invention is to polymerize a high polyurethane filter and a matting mat in order to spray the foamed resin solution is sprayed foamed resin solution from the top of the polymer and then to thermo-pressure molding, after molding the hot melt film on the back It is achieved by the method of manufacturing the sunshade of an automotive sunroof in which the bonded interior material is superimposed and adhesively formed by heating and pressing.

본 발명에 이용되는 폴리우레탄필터(20)는 약20~35kg/㎥의 고밀도로서, 그 자체로서 상당한 휨강도를 지니게 되고 또 그 표면과 이면에 발포수지액이 분사되면 발포수지액은 밀도가 높은 폴리우레탄필터(20)의 표면과 이면에 앝게 침투하여 발포성형시 폴리우레탄필터(20)와 촙매트(10)(30)를 일체로 형성해 주도록 함으로 서, 폴리우레탄필터(20)에 흡수되는 발포수지액의 흡수량이 적은만큼 그 표면과 이면에는 다량의 발포수지액이 잔류하여 발포성형시 상하촙매트(10)(30)의 노출방지로 매끈한 외관을 유지할 수가 있어 발포수지액의 필요량 감소 및 표면재와 이면재를 없애주는데 따라 재료비를 절감해 줄 수가 있게 되고 또 발포수지액이 폴리우레탄필터(20)에 얕게 침투되게 하는데 긴 시간을 필요로 하지 않게 됨은 물론 표면재와 이면재를 없애주는데 따른 제조공정단축으로 현저한 생산성 향상을 가져올 수가 있게 된다.Polyurethane filter 20 used in the present invention is a high density of about 20 ~ 35kg / ㎥, and has a considerable bending strength in itself and when the foamed resin solution is sprayed on the surface and the back, the foamed resin solution is a high density poly The foamed resin absorbed by the polyurethane filter 20 by penetrating the surface and the back of the urethane filter 20 so as to integrally form the polyurethane filter 20 and the mat 10 and 30 during foam molding. As the amount of liquid absorbed is small, a large amount of foamed resin liquid remains on the surface and the rear surface thereof, and thus, when foaming, a smooth appearance can be maintained by preventing exposure of the upper and lower mats 10 and 30. The material cost can be reduced by removing the backing material, and the foamed resin liquid does not need long time to penetrate shallowly into the polyurethane filter 20, as well as removing the surface material and the backing material. It is not able to get a significant improvement in productivity, shorten the production process.

또한 폴리우레탄필터(20)에 대한 발포수지액의 침투량이 적고 또 표면재와 이면재를 없애준만큼 제품의 무게를 감소시켜 줄 수가 있어 경량화를 만족시켜 줄 수가 있고 또 이용되는 폴리우레탄필터(20)의 밀도가 높은만큼 그 자체로서 상당한 휨강도를 지니게 되며 여기에 그 표면과 이면의 표층에 침투하여 발포된 발포수지와 촙매트(10)(30)의 강도가 더해지게 되므로 선쉐이드(90)로서 요구되는 충분한 강도를 지닐 수가 있게 된다.In addition, the amount of the foamed resin solution penetrated into the polyurethane filter 20 is reduced, and the weight of the product can be reduced by eliminating the surface material and the back material, which can satisfy the weight reduction and the density of the polyurethane filter 20 used. It has a high flexural strength per se as it is high, and the strength of the foamed resin and the wet mats 10 and 30, which penetrates the surface and the back surface of the surface, is added to it, so that it is sufficient as the sunshade 90 required. It can have strength.

더 나아가 성형후에는 그 이면에 핫멜트필름(70)이 부착된 내장재(80)를 겹쳐서 열가압을 통하여 접착고정해 주도록 함으로서 내장재(80)의 접착을 위한 작업인력과 시간을 줄여줄 수가 있어 더욱 현저한 생산성 향상을 가져올 수가 있는 등의 효과가 있는 것이다.Furthermore, after molding, it is possible to reduce the work force and time for adhesion of the interior material 80 by stacking the interior material 80 having the hot melt film 70 attached thereto on the back side thereof and fixing the adhesive material by thermal pressure. There is such an effect as to bring productivity improvement.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거 설명하기로 하며, 다만 본 발명은 그 기술적 사상이나 전망으로부터 개별적으로 이해되어져서는 안되 며, 당업자에 의하여 다양하게 실시될 가능성이 있는 것이면 모두 동일기술범주 내에 속한다 할 것이다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, but the present invention should not be understood individually from the technical idea or the prospect, and all of the same technologies may be implemented by those skilled in the art. Will fall within the category.

본 발명은 촙매트(Chop Mat)(10) 상에 발포수지액을 1차분사하고, 발포수지액이 분사된 촙매트(10)상에 폴리우레탄필터(20) 및 촙매트(30)를 차례로 중합하고, 중합된 촙매트(30) 상부로부터 발포수지액을 2차분사한 다음 열가압에 의해 발포수지액이 발포되게 하며, 발포성형후 발포수지층(40)(50)에 의해 입체적으로 성형된 가성형품(60)의 이면에는 핫멜트필름(Hot-Melt Film)(70)이 부착된 내장재(80)를 겹쳐서 열가압에 의해 접착고정되게 하여 완성된 선쉐이드(Sun Shade)(90)를 얻도록 구성된다.The present invention primarily sprays the foamed resin solution on the Chop Mat 10, and in turn, the polyurethane filter 20 and the wet mat 30 on the wet mat 10 to which the foamed resin solution is injected. After the polymerization, the second injection of the foamed resin solution from the top of the polymerized wet mat 30, the foamed resin solution is foamed by thermal pressure, and after the foaming molded three-dimensionally by the foamed resin layer (40) (50) On the back side of the preformed molded product 60, a hot-melt film 70 is laminated with an interior material 80 to which the hot-melt film 70 is attached to be fixed by hot pressing to obtain a completed sun shade 90. It is configured to.

본 발명에 이용되는 촙매트(10)(30)는 글라스화이바(Glass Fiber) 원사를 10~80mm로 컷팅하여 바인더를 혼합한 다음 얇게 편 상태에서 가압롤러 사이로 통과시켜서 성형하고, 성형후 건조한 다음 원하는 규격으로 재단하여 된 것으로서, 글라스화이버를 이용하여 매트화하고 또 얻고자 하는 선쉐이드(90)의 경량화 내지는 강도조건등에 따라 100~300g/㎥의 밀도를 갖도록 한 것이면 모두 만족한다.The wet mat (10) (30) used in the present invention is cut into glass fiber yarn (Glass Fiber) yarn 10 ~ 80mm mixed with a binder and then passed through the pressure roller in a thinly sliced state, and then molded and dried after molding As cut to the standard, all of them are satisfied as long as they have a density of 100 to 300 g / m 3 according to the weight reduction or strength conditions of the sunshade 90 to be matted using glass fibers and to be obtained.

또한 기반재로 이용되는 폴리우레탄필터(20)는 일반 모든 필터가 갖는 특성상 다공성을 지니게 되나, 그 밀도는 20~35kg/㎥로서 원하는 규격으로 재단하여 사용하게 되는데, 밀도가 높은만큼 기반재로서 요구되는 상당한 휨강도를 지니게 되고 또 발포수지액의 흡수율을 낮춰주게 된다.In addition, the polyurethane filter 20 used as the base material has a porosity due to the characteristics of all the general filters, the density is 20 ~ 35kg / ㎥ is used to cut to the desired standard, the higher density required as the base material It has a considerable bending strength, which lowers the absorption rate of the foamed resin liquid.

따라서 본 발명은 촙매트(10) 상에 발포수지액을 분사하고 또 발포수지액이 분사된 촙매트(10) 상에 폴리우레탄필터(20)와 촙매트(30)를 차례로 중합한 다음 촙매트(30) 상부로부터 발포수지액을 재분사해 주게 되면 2차에 걸쳐 분사된 발포수지액이 촙매트(10)(30)를 통하여 폴리우리탄필터(20)에 흡수되는데, 이때 폴리우레탄필터(20)는 20~35kg/㎥의 고밀도로서 흡수율이 낮은만큼 발포수지액은 폴리우레탄필터(20)의 표면과 이면에 얕게 침투하게 되므로 발포수지액의 필요량 감소를 가져오게 된다.Therefore, the present invention sprays the foamed resin solution on the fin mat 10 and polymerizes the polyurethane filter 20 and the fin mat 30 on the fin mat 10 in which the foamed resin liquid is sprayed, followed by the fin mat. (30) When the foamed resin solution is re-injected from the upper portion, the foamed resin solution sprayed on the secondary is absorbed into the polyurethane filter 20 through the wet mats 10 and 30, wherein the polyurethane filter 20 ) Is a high density of 20 ~ 35kg / ㎥, low absorption rate, so that the foamed resin liquid is to penetrate shallowly to the surface and the back of the polyurethane filter 20, resulting in a decrease in the required amount of the foamed resin liquid.

또한 발포수지액은 폴리우레탄필터(20)의 표면과 이면에 얕게 침투하게 되나, 얕게 침투한 발포수지액만으로도 발포성형시 촙매트(10)(30)와 폴리우레탄필터(20)를 강한 일체감을 갖도록 성형해 줄 수가 있게 되고 또 폴리우레탄필터(20)의 흡수율이 낮은만큼 폴리우레탄필터(20)의 표면과 이면에는 다량의 발포수지액이 잔류하여 발포성형시 폴리우레탄필터(20)의 표면과 이면에 중합된 촙매트(10)(30)가 발포수지층(40)(50) 내에 매몰되므로 별도의 표면재나 이면재 없이도 발포수지층(40)(50)에 의해 매끈한 외관을 유지하게 된다.In addition, the foamed resin liquid penetrates shallowly into the surface and the back of the polyurethane filter 20, but the foam mat liquid only penetrates the mat mat 10 and the polyurethane filter 20 with a strong sense of unity during foaming. Since the water absorption rate of the polyurethane filter 20 is low, a large amount of foamed resin liquid remains on the surface and the back of the polyurethane filter 20 so that the surface of the polyurethane filter 20 and Since the wet mats 10 and 30 polymerized on the back surface are buried in the foamed resin layers 40 and 50, a smooth appearance is maintained by the foamed resin layers 40 and 50 without a separate surface or backing material.

또한 폴리우레탄필터(20)의 흡수율이 낮아 발포수지액이 그 표면과 이면에 얕게 침투된다 하더라도 폴리우레탄필터(20)는 고밀도로서 그 자체로서 상당한 휨강도를 지니게 되는데, 여기에 그 표면과 이면에 얕게 침투하여 발포된 발포수지층(40)(50)과 상기 발포수지층(40)(50)에 의해 일체화된 촙매트(10)(30)에 의해 휨강도가 더해져 선쉐이드(90)로서 요구되는 충분한 휨강도를 지니게 된다.In addition, even though the water absorption of the polyurethane filter 20 is low, even if the foamed resin liquid penetrates shallowly on the surface and the back, the polyurethane filter 20 has a high bending strength by itself as a high density, which is shallow on the surface and the back. Sufficient flexural strength is added by the wet mats 10 and 30 integrated by the foamed resin layers 40 and 50 that have penetrated and foamed, and the foamed resin layers 40 and 50, thereby being sufficient as the sunshade 90. It has flexural strength.

그리고 폴리우레탄필터(20)의 흡수율이 낮아 발포수지액의 필요량이 감소되고 또 표면재와 이면재 없이 폴리우레탄필터(20) 및 상하촙매트(10)(30)로 구성되는만큼 재료비를 절감할 수가 있게 됨은 물론 더욱 경량화 할 수가 있게 된다.In addition, since the absorption rate of the polyurethane filter 20 is low, the required amount of the foamed resin solution is reduced, and the material cost can be reduced as it is composed of the polyurethane filter 20 and the upper and lower mats 10 and 30 without the surface material and the back material. Of course, the weight can be reduced.

더 나아가 발포수지액의 발포를 통하여 얻게 되는 가성형품(60)에 내장재(80)를 접착형성해 줌에 있어서도 핫멜트필름(70)이 부착되어 디자인컷팅된 내장재(80)를 가성형품(60)의 이면과 겹쳐서 열가압하여 접착해 주면 되는데, 이때 핫멜트필름(70)은 120~180℃의 온도하에서 접착력을 발휘하게 되므로 가성형품(60)과 내장재(80)의 공급이 용이하게 이루어질 수가 있고 또 접착작업이 적은 인력으로 간단하고 신속하게 이루어질 수가 있게 되며, 내장재(80)의 접착에 앞서 양측 가이드부에 실리콘등으로 제작되는 마찰용 패드를 미리 부착하여 내장재(80)가 마찰용 패드를 감싸주도록 하게 되면 마찰용 패드까지도 견고히 부착고정해 줄 수가 있게 되는 것이다.Furthermore, even when the interior material 80 is adhesively formed on the pseudo molded article 60 obtained through the foaming of the foamed resin solution, the hot melt film 70 is attached to the back surface of the pseudo molded article 60. The adhesive layer is heated and pressurized, and the hot melt film 70 exhibits an adhesive force under a temperature of 120 to 180 ° C., so that the provision of the pseudo-molded product 60 and the interior material 80 can be easily performed. When the interior material 80 is wrapped around the friction pad by attaching a friction pad made of silicon or the like to the guide parts on both sides before adhesion of the interior material 80, the interior material 80 can be easily and quickly made. Even the friction pad can be firmly attached and fixed.
