Description

차량용 내장재의 제조방법{MANUFACTURING METHOD OF INTERIOR FOR VEHICLE}MANUFACTURING METHOD OF INTERIOR FOR VEHICLE}

본 발명은 차량용 내장재의 제조방법에 관한 것으로, 보다 구체적으로 설명하면, 기재의 표면에 표피재를 일체로 사출성형할 때 표피재의 표면이 과도하게 손상되는 것을 방지할 수 있는 차량용 내장재의 제조방법에 관한 것이다.
The present invention relates to a method for manufacturing a vehicle interior material, and more specifically, to a method for manufacturing a vehicle interior material that can prevent the surface of the skin material from being excessively damaged when the skin material is injection molded integrally on the surface of the substrate. It is about.

일반적으로 천이 인서트 되면서 사출성형 하여 제조된 성형품을 주로 자동차용 내장재로 도어트림, 필러, 트렁크매트, 패키지트림, 헤드라이너 등이 있으며, 가격이 저렴한 국민차나 소형차 또는 중대형의 고급차종에 따라 그 상용되는 내장재는 그 재질과 구성이 서로 상이하다 할 수 있다.In general, molded products manufactured by injection molding while inserting cloth are mainly used as interior materials for automobiles, such as door trims, fillers, trunk mats, package trims, and headliners.These are commonly used according to low-priced national cars, small cars, and medium and large luxury cars. The interior material can be said to be different in material and composition.

즉, 합성수지로만 사출성형 된 내장재를 사용하거나, 합성수지표면에 연질의 표피재를 부분 부착한 내장재를 사용하기도 하며, 그 외의 차종은 기재표면 전체에 표피재를 접착하되 그 테두리를 함께 트리밍한 것을 사용하거나 또는 촉감을 더 좋게 하기 위하여 합성수지표면에 고급의 표피재을 접착한 후 그 표피재 테두리를 기재내면에 감싸 접착시킨 것을 사용하기도 한다.In other words, it is possible to use interior materials that are injection-molded only with synthetic resin, or interior materials with soft skin parts partially attached to the surface of synthetic resins.Other car models use the ones that adhere the skin material to the entire surface of the substrate, but trim the edges together. In order to make or feel better, a high-quality skin material is attached to the synthetic resin surface, and then the edge of the skin material is wrapped around the inner surface of the substrate and then used.

자동차내장재의 일반적인 제조방법을 살펴보면, 자동차 내장재를 사출성형한 후에 표피재를 부착하는 방식으로는 수동으로 접착제에 의해 자동차 내장재의 외부에 부착시키는 방법과, 1차 사출성형한 후에 성형물 표면에 표피재를 적층 한 후에 다시 사출성형 하는 방법과, 표피재를 내장시켜 사출과 동시에 표피재가 부착된 자동차내장재를 제조하는 방법이 있으나, 첫 번째의 경우에는 수작업으로 비경제적이며, 두 번째의 경우 품질은 좋으나 두 번 사출성형해야하는 불편함이 있으며, 세 번째의 경우에는 저압사출방식과 고압사출방식이 있는데 이중 저압사출방식은 사출액을 주입할 때 저압인 반면 표피재를 금형 내에 내장시켜 상금형으로 눌러 기재를 성형할 때는 고압이 필요하다.Looking at the general manufacturing method of automotive interior materials, the method of attaching the skin material after the injection molding of the car interior material is a method of manually attaching to the exterior of the car interior material by adhesive, and the skin material on the surface of the molding after the first injection molding There is a method of injection molding again after lamination, and a method of manufacturing a car interior material having a skin material attached at the same time by inserting the skin material, but in the first case, it is uneconomical by hand, and in the second case, the quality is good. In the third case, there is the inconvenience of injection molding, and in the third case, there is a low pressure injection method and a high pressure injection method. The low pressure injection method has a low pressure when injecting the injection liquid, whereas the skin material is embedded in the mold to press the base mold. High pressure is required when molding.

이러한, 저압사출방식은 자동차 내장재성형과 표피재의 접착이 동시에 이루어짐으로써 생산성이 좋으나 표피재의 일측면에 기재가 되는 고온의 사출액을 주입한 후 냉각이 이루어지기 때문에 표피재의 표면이 고온에 열손상되어 표피재의 표면이 경화되어 쿠션감이 저하되고, 색깔이 변색되는 등의 문제점 있다.
The low pressure injection method has high productivity by simultaneously molding the interior of the automobile and adhering the skin material, but the surface of the skin material is thermally damaged at a high temperature because the cooling is performed after the injection of a high temperature injection liquid that is described on one side of the skin material. There is a problem that the surface of the skin material is cured, the cushioning is lowered, and the color is discolored.

도 1 내지 도 2를 참조하면, 본 발명의 일실시예에 따른 차량용 내장재의 제조방법은 표피재 삽입단계(S10), 수지공급단계(S30), 1차 냉각단계(S40), 2차 냉각단계(S50), 취출단계(S60)를 포함하여 구성된다.1 to 2, a method for manufacturing a vehicle interior according to an embodiment of the present invention is the skin material inserting step (S10), the resin supply step (S30), the first cooling step (S40), the second cooling step (S50), taking out step (S60) is configured.

표피재 삽입단계(S10)는 하부금형(10)과 상부금형(20) 사이에 형성된 성형공간부(30)에 표피재(40)가 위치되도록 삽입하고 하부금형(10)과 상부금형(20)을 형합한다.Skin material inserting step (S10) is inserted so that the skin material 40 is located in the molding space portion 30 formed between the lower mold 10 and the upper mold 20 and the lower mold 10 and the upper mold 20 To match.

여기서, 표피재(40)는 열가소성 올레핀(Thermoplastic Olefin: TPO)으로 이루어지며, 바람직하게는 폴리프로필렌(PP), 폴리에틸렌(PE), 폴리우레탄(PU)을 포함하여 이루어진다.Here, the skin material 40 is made of thermoplastic olefin (TPO), preferably made of polypropylene (PP), polyethylene (PE), polyurethane (PU).

아울러, 표피재 삽입단계(S10)에서 이면재 삽입단계(S20)가 더 포함될 수 있으며, 이러한, 이면재(미도시)는 표피재(40)의 표면이 후술하는 수지공급단계(S30)에서 고온으로 공급되는 액상수지상태의 기재(50)에 의해 열손상되지 않도록 표피재(40)의 표면을 보호하는 역할을 한다.In addition, the backing material inserting step (S10) may further include a backing material inserting step (S20), such, the backing material (not shown) is supplied at a high temperature in the resin supply step (S30) to be described later the surface of the skin material 40 It serves to protect the surface of the skin material 40 to be thermally damaged by the substrate 50 in the liquid resin state.

수지공급단계(S30)는 하부금형(10)과 상부금형(20) 사이에 형성된 성형공간부(30)에 위치된 표피재(40)의 일측면에 기재층이 형성되도록 액상수지상태의 기재(50)를 공급한다. 이러한, 액상수지의 기재(50)는 올리핀계 수지에 발포제, 가교제, 가교조제 등이 첨가되어 이루어진다.Resin supply step (S30) is a substrate in a liquid resin state so that the base layer is formed on one side of the skin member 40 located in the molding space 30 formed between the lower mold 10 and the upper mold 20 ( 50). The base material 50 of the liquid resin is formed by adding a blowing agent, a crosslinking agent, a crosslinking aid and the like to an olefinic resin.

1차 냉각단계(S40)는 고온으로 주입되는 액상수지상태의 기재(50)에 의해 표피재(40)의 표면이 열손상되어 경화됨으로써 쿠션감이 저하되고, 표피재(40)의 색깔이 변색되는 것을 방지되도록 상부금형을 형개시킨 후 소정 시간 유지함으로써 이루어지는데, 바람직하게는 표피재(40)의 재질에 따라 3 ~ 10초가 유지된다.In the first cooling step (S40), the surface of the skin material 40 is thermally damaged and cured by the substrate 50 in a liquid resin state injected at a high temperature, thereby lowering the feeling of cushioning and discoloring the color of the skin material 40. It is made by maintaining a predetermined time after opening the upper mold to prevent it from being, preferably 3 to 10 seconds is maintained depending on the material of the skin material (40).

2차 냉각단계(S50)는 1차 냉각단계(S40)에서 형개후 유지되는 상부금형(20)을 하부금형(10)에 형합시켜 표피재(40)와 기재(50)로 이루어진 내장재의 형상을 고정 유지하며 또한 표피재(40)와 기재(50)를 별도의 접착제 없이 일체로 성형하게 된다.Secondary cooling step (S50) is the upper mold 20 to be maintained after the mold opening in the first cooling step (S40) to the lower mold 10 by molding the shape of the interior material consisting of the skin material 40 and the base material 50 In addition, the skin material 40 and the base material 50 are fixed and held together without a separate adhesive.

취출단계(S60)는 상부금형(20)을 하부금형(10)으로부터 형개시킨 후 표피재(40)와 기재(50)가 일체로 성형된 내장재를 취출한다. In the taking out step S60, the upper mold 20 is opened from the lower mold 10, and then the interior material in which the skin 40 and the substrate 50 are integrally molded is taken out.

따라서, 본 발명의 일실시예에 따른 차량용 내장재의 제조방법은 차량용 내장재의 사출성형시 고온으로 주입되는 액상수지상태의 기재에 의해 표피재의 표면이 고온에 열손상되어 표피재의 표면이 경화되어 쿠션감이 저하되고, 색깔이 변색되는 것을 방지할 수 있는 효과가 있다.Therefore, the method of manufacturing a vehicle interior according to an embodiment of the present invention heat-damages the surface of the skin material at a high temperature by the liquid resin state of the base material injected at a high temperature during the injection molding of the vehicle interior material to harden the surface of the skin material to cushion This decreases and there is an effect that can prevent the color from discoloring.
