Description

탄소 섬유 소재를 이용한 차량용 보호커버 및 그 제조방법{Protective cover for vehicle using carbon fiber material and manufacturing method thereof}Protective cover for vehicle using carbon fiber material and manufacturing method

본 발명은 돌이나, 나무, 수풀 등으로 부터의 마찰 및 오물이 차량 내부로 유입되는 것을 방지하기 위하여 오프로드형 차량의 적용되는 프로텍티브 커버에 관한 것이다.The present invention relates to a protective cover applied to an off-road vehicle in order to prevent the friction and dirt from stones, trees, bushes and the like to enter the vehicle.

자동차 프론트 커버는 자동차 범퍼 및 보닛에 부착하여 애기치 않은 바닥의 잔해로부터의 손상과 벌레나 오물 등으로 부터의 오염을 방지하기위해 사용되어진다. 개발 초기의 프론트 커버 제품은 플라스틱 커버형 제품이 개발되었으며 범퍼에 부착시켜 단순히 자동차 보호용으로 개발되었다. 하지만 주행시 공기저항이 상승되는 문제점과 무게 증가로 인한 연비 감소의 문제점을 보였으며 이는 차량의 경량성 및 연비 효율성이 중요시되는 현재의 자동차 산업 트랜드에 벗어난다.The front cover of the car is attached to the bumper and bonnet of the car to prevent damage from debris on the bottom of the floor and contamination from bee or dirt. In the early stage of development, a plastic cover type product was developed and was simply developed to protect a car by attaching it to a bumper. However, it showed a problem of increasing air resistance while driving and reducing fuel economy due to weight increase, which is outside of the current automotive industry trend in which weight and fuel efficiency of vehicles are important.

이후 기존 플라스틱형 커버 제품의 문제점인 공기저항과 연비효율성을 보완한 가죽형, 직물형 프론트 커버 제품이 출시되었다. 가죽 소재로 제작된 제품의 경우, 일반 직물 소재에 비해 마찰에는 좀 더 강할 수 있으나 수분에 취약하여 주행 시에 내구성이 약화될 우려가 있다. 또한, 가죽 제품은 비오는 날과 같이 습도가 높은 날에 착용할 경우 차량 외부의 부식 등 손상을 일으킬 수 있으며 제품 자체에도 큰 손상을 일으킬 수 있기 때문에 자동차용 커버 소재로는 적합하지 않은 것으로 판단된다. 직물 소재의 경우, 가죽 소재보다 내구성이 약하여 마찰 시 쉽게 손상될 수 있고, 내구성이 약하여 제품을 오래 사용할 수 없다. 또한, 직물 소재 자체가 일광에 약한 부분이 있기 때문에 이에 대한 변색 또는 손상이 쉽게 일어날 수 있다. 이렇듯, 기존에 사용된 Front-End 커버의 소재들에는 각각의 단점이 있으며, 이러한 소재들의 단점을 보완하여 제품을 제작하기 위해 가볍고 우수한 강도로 내충격성 및 보호성이 강한 소재를 활용하여 손상을 최소화하고 경량성을 부여할 수 있는 소재를 이용해 개발할 필요성이 있다.Since then, leather- and textile-type front cover products have been released to complement the air resistance and fuel efficiency of the plastic cover products. Products made of leather may be more resistant to friction than ordinary fabrics, but are vulnerable to moisture, which may weaken durability when driving. In addition, leather products may cause damage such as corrosion on the outside of the vehicle when worn on high humidity, such as rainy days, and may cause great damage to the product itself. In the case of textile material, it is less durable than leather material, so it can be easily damaged by friction, and the durability is weak, so the product can not be used for a long time. In addition, since the fabric material itself has a weak part in daylight, discoloration or damage thereof may easily occur. As such, the materials of the front-end cover used in the past have their respective disadvantages, and the damage is minimized by utilizing the material having strong impact resistance and protection with light and excellent strength to make up the product by supplementing the disadvantages of these materials. And there is a need to develop using a material that can give light weight.

본 발명은 강도가 강한 탄소섬유 표면을 기재로 사용하고 라미네이팅 처리하여 기존 제품에서 나타나는 내마모성 및 내구성이 떨어져 마찰에 의한 제품 표면이 손상되는 문제를 해결하는 것을 목적으로 한다.An object of the present invention is to solve the problem that the surface of the product is damaged by friction due to the wear resistance and durability of the existing product by using a strong carbon fiber surface as a substrate and laminating.

또한 본 발명은 종래의 가죽이나 PVC 제품은 또한 우천시 수분을 외부로 발산하기 힘들어 도장면에 부식을 야기시켰던 문제점을 해결하기 위하여, 표면 스프레이 코팅을 통한 표면 발수성을 증진시켜 것을 목적으로 한다.In addition, the present invention is to improve the surface water repellency through the surface spray coating in order to solve the problem that the conventional leather or PVC products are difficult to dissipate moisture in the rain, causing corrosion on the painted surface.

본 발명은 탄소섬유 제직물 기재(10)와, 상기 기재에 라미네이트된 필름(20) 및, 상기 필름에 형성된 코팅층(30)을 포함하는 강도가 향상된 전면부; 및The present invention includes a carbon fiber woven base material 10, a front portion having an improved strength including a film 20 laminated to the base material, and a coating layer 30 formed on the film; And

상기 전면부와 본딩처리되어 스크래치를 방지하는 폴리프로필렌 부직포(40)인 후면부;를 포함하는 차량용 보호커버를 제공함을 특징으로 한다.It is characterized in that it provides a protective cover for a vehicle comprising a; a rear portion of the polypropylene nonwoven fabric 40 is bonded with the front portion to prevent scratches.

상기 탄소섬유 제직물은 3K와 12K인 것이 바람직하다.The carbon fiber woven fabric is preferably 3K and 12K.

또한 상기 탄소섬유 제직물은 실란 커플링제로 표면처리 되는 것을 특징으로 한다. 이종 소재간의 계면 접착강도를 향상시키기 위하여 커플링제(coupling agent) 처리가 필요하며, 본 발명에서와 같이 탄소섬유와 열가소성 수지의 라미네이팅을 위해서 탄소섬유의 표면 처리를 통한 표면 활성화 시킨다.In addition, the carbon fiber woven fabric is characterized in that the surface treatment with a silane coupling agent. In order to improve the interfacial adhesion strength between different materials, a coupling agent treatment is required, and surface activation of the carbon fibers is performed for surface lamination of the carbon fibers and the thermoplastic resin as in the present invention.

상기 탄소섬유 제직물에 라미네이트되는 필름은 TPU, PVC, PP, PE 필름인 것을 특징으로 한다. 또한 상기 필름은 열가소성 수지 필름인 것이 바람직하다.The film laminated on the carbon fiber woven fabric is characterized in that the TPU, PVC, PP, PE film. Moreover, it is preferable that the said film is a thermoplastic resin film.

본 발명에 있어서, 상기 필름층 상부에는 방오, 발수를 위한 코팅층이 형성된 것을 특징으로 한다. In the present invention, a coating layer for antifouling and water repellent is formed on the film layer.

한편, 본 발명의 보호커버의 후면부는 차량표면과 접합성을 올리고 차량 외부에 대한 충격 및 환경적 요인으로부터 발생되는 차량 외부의 스크레치 및 찌그러짐 등의 손상을 최소화하고, 통기성, 신축성의 증진 위해 폴리프로피렌 소재의 부직포를 사용하는 것을 특징으로 한다. 폴리프로필렌 원사의 경우 표면에 접합성을 향상시키기 위해 펠트 제작시 마찰계수가 높은 Filament 소재를 사용하는 것이 바람직하며 Denier당 Filament 개수가 낮은 것이 좋다. 현재 가염성 PP75/24F 원사를 사용하여 부직포를 제작하였다. 부직포두께는 2mm~2.5mm(탄소 및 M 아라미드 복합재료 두께: 0.3~0.4mm, Film 두께: 0.2~0.3mm)인 것이 상기 기능을 가짐과 동시에 충격을 흡수하기 위해 바람직하다.On the other hand, the rear portion of the protective cover of the present invention increases the adhesion to the vehicle surface and minimizes damages such as scratches and dents from the outside of the vehicle generated from impacts and environmental factors on the outside of the vehicle, and improves breathability and elasticity It is characterized by using the nonwoven fabric of the material. In the case of polypropylene yarns, it is desirable to use a filament material with a high friction coefficient when producing felts and to have a low number of filaments per denier in order to improve adhesion to the surface. Nonwoven fabrics are now manufactured using chlorinated PP75 / 24F yarns. The nonwoven fabric thickness is preferably 2 mm to 2.5 mm (carbon and M aramid composite thickness: 0.3 to 0.4 mm, film thickness: 0.2 to 0.3 mm) in order to have the above functions and to absorb shock.

한편, 본 발명의 또 다른 측면은 탄소섬유 제직물 기재를 준비하는 단계;상기 탄소섬유 제직물을 실란커플링제로 표면처리하는 단계;상기 표면처리된 탄소섬유 제질물 위에 필름을 라미네이트하는 단계;상기 필름 위에 발수 방오를 위한 코팅제를 스프레이 코팅하여 코팅층을 형성하여 자동차 보호커버의 전면부를 제조하는 단계;및, 상기 전면부의 탄소섬유 제직물 후면에 스크래치를 방지하는 폴리프로필렌 부직포인 후면부를 본딩하는 단계;포함하는 차량용 보호커버의 제조방법이다.On the other hand, another aspect of the present invention comprises the steps of preparing a carbon fiber woven fabric substrate; surface treatment of the carbon fiber woven fabric with a silane coupling agent; laminating a film on the surface-treated carbon fiber material; Forming a coating layer by spray-coating a coating agent for water repellent antifouling on the film to manufacture a front part of a car protective cover; and bonding a rear part of a polypropylene nonwoven fabric to prevent scratches on the back of the carbon fiber woven fabric of the front part; Method of manufacturing a protective cover for a vehicle comprising.

본 발명은 고강도, 고탄성의 특성을 지닌 섬유로 탄소섬유를 사용하여 자동차 중량에도 큰 영향을 끼치지 않으면서도 여러 외부 마찰이나 충격에 잘 견디는 제품을 제조하고 주행시 예기치 않은 돌, 나무, 수풀과의 마찰과 오물 벌레 등의 각종 먼지로부터 오염으로부터 차량 도장면을 보호하고자 한다. The present invention is a fiber having high strength and high elasticity, using carbon fiber to produce a product that withstands a lot of external friction or impact without significantly affecting the weight of the car and friction with unexpected stones, trees, bushes while driving To protect the painted surface of the vehicle from contamination from various dusts such as dirt and insects.

본 발명의 자동차 본닛 및 범퍼 등의 프로텍티브 커버 제품은 전면부인 라미네이팅된 슈퍼섬유와 후면부인 부직포를 본딩 및 봉제시킨 제품으로 기존에 PVC계열의 제품에 비해 강도를 향상시키며 전면부에 특수 스프레이 코팅을 처리함으로써 발수성 및 화학적 기계적 강도를 증진시킨다.The protective cover products such as the bonnet and the bumper of the present invention are bonded and sewn with the laminated super fiber and the nonwoven fabric of the rear part as the front part to improve the strength compared to the products of the PVC series and provide a special spray coating on the front part. Treatment enhances water repellency and chemical mechanical strength.

본 발명은 탄소섬유를 Front-End Cover에 사용할 경우, 차체의 중량이 낮아지게 되며, 약 10% 낮아지게 되면 기존의 차량보다 연비가 3% 이상 상승하고 엑셀레이터의 Perform이 약 8% 이상 증가하며 배기가스가 줄어들고 제동거리가 5% 이상 단축되는 등 여러 방면으로 큰 영향을 미치게 된다. 그러므로 차체 중량에 최대한 영향을 주지 않기 위해 가벼운 소재의 사용이 필요할 것으로 보이며, 슈퍼섬유를 이용해 제작하려는 이번 Front-End 커버는 이에 최적화된 제품이라고 볼 수 있겠다. 또한 슈퍼섬유 표면을 TPU 수지와 같은 열가소성 수지로 라미네이팅을 진행하여 기존 제직섬유 및 가죽 제품에 비해 더 높은 flexibility로 인하여 차량 피팅성이 증가되며 라미네이팅 제품 표면에 발수성 및 강도 개선을 위한 스프레이 코팅처리를 통하여 제품의 발수성을 극대화하여 기존제품에서 나타난 잔존 수분에 의한 표면 부식 등의 문제와 직물 및 가죽 표면이 자갈, 나무, 수풀 등에 의해 손상되어지는 현상을 해결하고자 하며 상기와 같이 Front-End 커버 제품으로써 최적의 물성을 구현하여 고객 요구에 부합하는 carbon fiber 소재를 이용한 오프로드 차량용 커스텀 핏 프로텍티브 프론트 앤드 제품을 개발하고자 한다.According to the present invention, when the carbon fiber is used for the front-end cover, the weight of the vehicle body is lowered. When the carbon fiber is lowered by about 10%, the fuel efficiency is increased by 3% or more, and the performance of the accelerator is increased by about 8% or more. This will have a big impact in many ways, including reduced gas and a shorter braking distance of more than 5%. Therefore, it is necessary to use light materials in order not to affect the weight of the body as much as possible, and this front-end cover, which is to be manufactured using super fiber, is optimized for this. In addition, the super fiber surface is laminated with a thermoplastic resin such as TPU resin, and thus the vehicle fitting property is increased due to the higher flexibility compared to the existing woven fiber and leather products. Maximize the water repellency of the product to solve the problems such as surface corrosion caused by residual moisture in the existing products and the phenomenon that the surface of the fabric and leather are damaged by gravel, wood, bushes, etc., as the front-end cover products as described above We will develop custom fit protective front end products for off-road vehicles using carbon fiber materials to meet customer needs.

2. 2. 탄소섬유Carbon fiber 제직물의Woven 표면 처리 Surface treatment

슈퍼섬유 중 탄소섬유는 일반적으로 carbon이 육각 고리로 이루어진 층상격자 형태로 이루어져 있으며 낮은 표면 자유에너지에 의해 타 소재와의 접착력이 떨어지며 아라미드 소재 또한 마찬가지이다. 이런 약한 결합력으로 인하여 계면 분리가 발생할 수 있다. 이종 소재간의 계면 접착강도를 향상시키기 위하여 플라즈마(plasma) 처리, 커플링제(coupling agent) 처리가 가능하며 본 발명에서와 같이 탄소섬유와 열가소성 수지의 라미네이팅을 위해서 탄소섬유의 표면 처리를 통한 표면 활성가 필요하다.Among the super fiber, carbon fiber is generally composed of layered lattice in which carbon is composed of hexagonal rings, and its adhesion to other materials is decreased by low surface free energy, and aramid material is the same. This weak bonding force can cause interfacial separation. Plasma treatment and coupling agent treatment are possible to improve the interfacial adhesion strength between different materials, and surface activation through surface treatment of carbon fibers is required for laminating carbon fibers and thermoplastic resins as in the present invention.

본 발명의 차량표면과 접합성을 올리고 차량 외부에 대한 충격 및 환경적 요인으로부터 발생되는 차량 외부의 스크레치 및 찌그러짐 등의 손상을 최소화하고, 통기성, 신축성의 증진 위해 폴리프로피렌 소재로 적정 두께의 Felt를 이용하였다. 폴리프로필렌 소재는 공정 수분율이 0이며 수분이 없어 세균 번식 등이 없고 100% 소수성 소재이며 나일론 폴리에스테르 섬유보다 물리적 특성 마찰에 더욱 강해 안감소재로 적합하다. 하지만 반응기가 없어 염색이 불가능하나 현재 개발된 가염성 폴리프로필렌 소재를 이용할 경유 차량 내부에 적합한 색상을 부여할 수 있다. 폴리프로필렌 원사의 경우 표면에 접합성을 향상시키기 위해 펠트 제작시 마찰계수가 높은 Filament 소재를 사용하는 것이 바람직하며 Denier당 Filament 개수가 낮은 것이 좋다. 현재 가염성 PP75/24F 원사를 사용하여 부직포를 제작하였다.In order to improve adhesion to the vehicle surface of the present invention and to minimize damages such as scratches and dents from the outside of the vehicle generated from impacts and environmental factors on the outside of the vehicle, and to improve breathability and elasticity, Felt of appropriate thickness is made of polypropylene material. Was used. Polypropylene material has 0 process moisture content, no moisture, no bacterial propagation, 100% hydrophobic material, and is more suitable for lining material because it is more resistant to physical property friction than nylon polyester fiber. However, dyeing is not possible due to the lack of a reactor, but the currently developed chlorinated polypropylene material can be used to give a suitable color inside the diesel vehicle. In the case of polypropylene yarns, it is desirable to use a filament material with a high friction coefficient when producing felts and to have a low number of filaments per denier in order to improve adhesion to the surface. Nonwoven fabrics are now manufactured using chlorinated PP75 / 24F yarns.
