따라서 상기한 방법으로 제조된 선셰이드 보드는 종래의 선셰이드 보드로 사용되고 있는 글라스울이나 폐섬유를 페놀수지 접착제로 혼합한 재료를 성형소재로 이용하던 것과 비교하면 성형성과 치수안정성이 우수한 양질의 성형소재를 공급 받을 수 있게 되는 효과가 있는 것이었으나 다음과 같은 미비점도 있는 것이었다.Therefore, the sunshade board manufactured by the above-described method is a high quality molding having excellent moldability and dimensional stability as compared to using a material mixed with glass wool or waste fiber, which is used as a conventional sunshade board, with a phenol resin adhesive as a molding material. It had the effect of being able to receive the material, but also had the following shortcomings.

즉 강도 증진을 위하여 소재투입량을 증진시킴과 동시에 강화제를 사용하게 되므로 그에 따른 중량의 증가를 가져오게 되고, 따라서 경량화를 요구하는 자동차용 부품으로는 바람직하지 못한 것이었다.In other words, to enhance the strength of the material input and at the same time to use the reinforcing agent to bring the increase in weight accordingly, it was not desirable for automotive parts that require a lighter weight.

따라서 본 발명의 목적은 제품의 경량화와 함께 굴곡강도 등의 기계적인 물성을 증진케하며, 또한 외부 표피재를 냉간성형시 동시 성형가능케 하여 공정 단축의 효과를 기대할 수 있도록 한 자동차용 선셰이드 보드 제조방법을 제공함에 있다.Accordingly, an object of the present invention is to manufacture a sunshade board for automobiles, which enables to reduce the weight of the product and to improve mechanical properties such as bending strength, and to enable simultaneous molding of the outer skin during cold forming, thereby achieving an effect of shortening the process. In providing a method.

상기한 목적을 달성하기 위한 본 발명은, 유리섬유와 폴리올레핀계섬유가 혼합제조된 글래스올레핀매트(GOM)를 이용하여 예열하고 냉간압착성형하여 열팽창매트용 소재(2)를 얻은 다음, 상기 열팽창매트용 소재(2)를 예열팽창시켜 구성함을 특징으로 한다.In order to achieve the above object, the present invention provides a thermal expansion mat material (2) by preheating and cold pressing using a glass olefin mat (GOM) in which glass fibers and polyolefin fibers are mixed, and then obtaining the thermal expansion mat. It is characterized by comprising preheating and expanding the dragon material (2).

본 발명은 유리섬유와 폴리올레핀계섬유가 혼합제조된 글래스올레핀매트(GOM)를 이용하여 열가소성 열팽창매트용 소재를 얻고, 그 양측으로 열경화성강화매트를 위치시킴으로써 가벼우면서도 기계적 물성이 우수한 고강성 복합소재를 얻을 수 있으며, 또한 압착성형시 표피재를 동시에 접합하여 성형할 수 있어 공정을 단축시킬 수 있게 되는 등의 효과가 있는 것이다.The present invention obtains a material for thermoplastic thermal expansion mat by using a glass olefin mat (GOM) made of a mixture of glass fiber and polyolefin fiber, and by placing the thermosetting reinforced mat on both sides of the high rigid composite material excellent in light and mechanical properties In addition, it is possible to obtain the skin material at the same time by pressing and molding at the same time, so that the process can be shortened.

이하 본 발명의 바람직한 실시 예들을 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 실시 예에 따른 자동차용 선셰이드 보드를 구성하는 열팽창매트용 소재의 구성도이고, 도 2는 열팽창매트 소재를 중앙기재로 한 선셰이드 보드의 분리구성도이며, 도 3은 도 2의 결합 구성도이다.1 is a configuration diagram of a material for thermal expansion mat constituting a sunshade board for automobiles according to an embodiment of the present invention, Figure 2 is a separate configuration diagram of a sunshade board with a thermal expansion mat material as a central substrate, Figure 3 It is a combined block diagram of FIG.

도 1 내지 도 3을 다함께 참조하면, 본 발명의 실시 예에 따른 자동차용 선셰이드 보드(A)는, 유리섬유와 폴리올레핀계섬유가 혼합된 소재를 매트상태로 제조한 글래스올레핀매트(Glass Olefin Mat,GOM)를 얻고, 이를 예열 및 냉간압착성형하여 일정두께를 갖는 열팽창매트용 소재(2)로 형성된다. 이 열팽창매트용 소재(2)를 중앙기재로 하여 양측으로 표면강도를 높이기 위해 열경화성수지가 코팅되어진 유리섬유매트(4)를 적층하고, 그 양측으로 부품의 물성과 외관을 향상시키기 위하여 고내열성 박막 필름(6)을 위치하여 각 단계별 성형공정을 통하여 필요한 제품을 얻는 것이다.1 to 3 together, the sun shade board (A) for automobiles according to the embodiment of the present invention, the glass olefin mat (Glass Olefin Mat) made of a material in which a glass fiber and a polyolefin-based fiber is mixed in a mat state , GOM), and preheated and cold pressed to form a material for thermal expansion mat 2 having a predetermined thickness. Using this thermal expansion mat material as a center substrate, a glass fiber mat 4 coated with a thermosetting resin is laminated to increase surface strength on both sides, and a high heat resistant thin film on both sides to improve the physical properties and appearance of the component. Positioning the film 6 is to obtain the required product through each step of the molding process.

제품성형을 위해 먼저 유리섬유와 폴리올레핀계섬유가 혼합된 글래스올레핀매트(GOM)를 예열과 냉간압착성형을 통하여 시트(sheet)상태로 준비하고, 준비된 고강성 시트는 다시 프레스 또는 가열챔버에서 가열됨으로서 팽창매트로 준비되어질 수 있으며, 이때 기계적 물성이 우수해진 경량의 중앙기재를 얻을 수가 있다.For product molding, first, a glass olefin mat (GOM) in which glass fibers and polyolefin fibers are mixed is prepared in a sheet state through preheating and cold press molding, and the prepared high rigid sheet is heated again in a press or a heating chamber. It can be prepared as an expansion mat, and at this time, it is possible to obtain a lightweight central substrate with excellent mechanical properties.

제품물성향상을 위한 열경화성수지를 롤코팅 또는 스프레이 방식을 통하여 유리섬유매트(4)에 코팅하게 되는데, 열경화성수지는 에폭시, 페놀, 불포화 폴리에 스테르 등이 사용되며, 그 중에서도 주로 불포화 폴리에스테르가 사용된다. 불포화 폴리에스테르 수지는 일반적으로 유리섬유로 강화되기 때문에 섬유강화 플라스틱(fiber reinforced plastics:FRP)이라 한다. 유리섬유뿐만 아니라 현무암섬유, 탄소섬유, 세라믹섬유와 같은 무기섬유류와, 나일론이나 테트론 같은 섬유도 사용되며 엔지니어링 플라스틱(공업용 플라스틱)으로도 쓰인다.Thermosetting resin for product properties is coated on the glass fiber mat (4) by a roll coating or spray method, thermosetting resin is epoxy, phenol, unsaturated polyester, etc., mainly unsaturated polyester Used. Unsaturated polyester resins are generally called fiber reinforced plastics (FRP) because they are reinforced with glass fibers. In addition to glass fibers, inorganic fibers such as basalt fibers, carbon fibers and ceramic fibers, as well as fibers such as nylon and tetron, are also used as engineering plastics.

이때 유리섬유매트(4) 대신 현무암섬유매트(4')를 사용하여도 되며, 각 매트 중량은 200∼700g/㎡의 면 밀도를 갖는 것이 좋으며, 요구되는 제품의 물성에 따라 가감할 수가 있다.At this time, the basalt fiber mat 4 'may be used instead of the glass fiber mat 4, and the weight of each mat preferably has a surface density of 200 to 700 g / m 2, and can be added or subtracted depending on the required physical properties of the product.

상기한 준비되어진 각각의 소재를 도 2에서와 같이 적층하여 성형용 금형상에 투입하여 가열압착성형을 1차적으로 하고, 1차 성형후 공기중에서 자연냉각을 통하여 부품성형을 종료할 수도 있으나, 보다 나은 외관과 물성을 위하여 2차적으로 성형용 금형상에서 냉각압착하여 줌으로서 보다 나은 물성을 확보한 제품을 얻을 수 있다. 또한 열가소성 열팽창매트용 소재(2)와 열경화성강화매트를 혼합 성형함으로써 경량이며, 기계적 물성이 뛰어난 복합성형 제품을 제공할 수 있게 된다.Each of the prepared materials is laminated as shown in FIG. 2 and put on a molding die to primarily perform heat compression molding, and after the first molding, molding of parts may be completed through natural cooling in air. For better appearance and physical properties, the product can be obtained by secondarily cooling and pressing on the molding die to secure better physical properties. In addition, by mixing and molding the thermoplastic thermal expansion mat material 2 and the thermosetting reinforced mat, it is possible to provide a composite molded product having a light weight and excellent mechanical properties.

또한 상기와 같이 성형된 소재를 이용하여 제품을 압착성형할때 제품의 외측에 부직포와 같은 표피재(8)가 위치되게 한 상태에서 성형하게 되면 표피재(8)와 제품이 일체로 접합 구성되어 표면이 매끈한 양질의 제품을 제공받을 수 있게 되므로 간단한 공정으로 표피재(8)를 일체화되게 할 수가 있다.In addition, when the molding using the molded material as described above in the state that the skin material 8 such as non-woven fabric is positioned on the outside of the product when the molding is formed, the skin material 8 and the product is integrally bonded Since it is possible to provide a high quality product with a smooth surface, the skin 8 can be integrated in a simple process.
