Description
본 발명은 자동차 부품 소재 강화용 아라미드 섬유의 제조방법에 관한 것으로서, 보다 구체적으로는 자동차 부품 소재용 열가소성 수지로 널리 사용되고 있으나 표면에 반응기가 없는 폴리프로필렌 수지와의 상용성 및 접착력을 향상시키는 계면 특성을 구비하는 자동차 부품 소재 강화용 아라미드 섬유의 제조방법에 관한 것이다.
The present invention relates to a method for producing aramid fibers for reinforcing automobile parts materials, and more particularly, to a method for producing aramid fibers for reinforcing aramid fibers for automobile parts, which is widely used as a thermoplastic resin for automobile parts, To an aramid fiber for reinforcing an automobile part material.
자동차 범퍼, 백빔 등과 같은 자동차 부품용 소재들은 (ⅰ) 열가소성 수지와 (ⅱ) 상기 열가소성 수지에 함침되어 있으며 강화용 섬유(Reinforcing fiber) 등이 일방향(Uni-Direction)으로 배열되어 있는 강화용 섬유 UD로 이루어진 프리프레그(Prepreg)를 원하는 형태로 성형, 열처리하여 제조된다.Materials for automobile parts such as automobile bumpers, back beams and the like are made of reinforcement fibers UD (hereinafter referred to as " reinforcing fibers UD ") in which the thermoplastic resin and (ii) the reinforcing fiber impregnated with the thermoplastic resin are arranged in a uni-direction Is prepared by molding and heat-treating a prepreg made into a desired shape.
상기 강화용 섬유 UD 대신에 강화용 섬유로 제직된 직물이 사용되기도 하였다.A fabric woven with reinforcing fibers was used instead of the reinforcing fibers UD.
자동차 부품 제조에 사용되는 상기 열가소성 수지로는 가격이 저렴하고 성형시간이 단축 가능한 폴리프로필렌 수지가 주로 사용되고 있다.As the thermoplastic resin used for manufacturing automobile parts, a polypropylene resin is inexpensive and the molding time is shortened.
한편, 자동차 부품 제조에 사용되는 상기 강화용 섬유(Reinforcing fiber)로는 유리섬유가 사용되어 왔으나 유리섬유의 경우 비중이 높아서 자동차의 경량화가 어려운 문제점이 있었다.On the other hand, glass fiber has been used as the reinforcement fiber used for manufacturing automobile parts, but glass fiber has a high specific gravity, which makes it difficult to reduce the weight of the automobile.
이와 같은 문제점을 해결하기 위해서 상기 강화용 섬유로 유리섬유 대신 탄소섬유를 사용하였으나, 탄소섬유는 비강성이 커서 내충격성이 떨어지는 문제점이 있었다.In order to solve such a problem, carbon fiber was used instead of glass fiber as the reinforcing fiber, but carbon fiber had a high non-rigidity and low impact resistance.
최근, 자동차의 경량화 및 내충격성 개선을 동시에 달성하기 위해서 상기 강화용 섬유로 내열성 및 고강도가 우수하면서도 동시에 내충격 특성이 뛰어난 아라미드 섬유를 사용하려고 많은 노력을 해왔지만, 통상적인 아라미드 섬유는 자동차 부품 제조에 가장 널리 사용되지만 표면에 반응기가 없는 폴리프로필렌 수지와 상용성 및 접착성이 떨어져 최종 제품인 자동차 부품의 파손강도가 크게 저하되는 문제가 발생되었다.
In recent years, in order to attain both light weight and improved impact resistance of automobiles, a lot of efforts have been made to use aramid fibers having excellent heat resistance and high strength as well as excellent impact resistance at the same time as the above reinforcing fibers. However, There is a problem that the breakage strength of the automobile parts, which is the final product, is greatly lowered because of the compatibility and adhesion with polypropylene resin which is most widely used but has no reactor on the surface.
본 발명의 과제는 내충격 특성이 우수함과 동시에 자동차 소재용 열가소성 수지로 널리 사용되고 있으나 표면에 반응기가 없는 폴리프로필렌 수지와의 상용성 및 접착력이 뛰어난 자동차 부품 소재 강화용 아라미드 섬유를 제조하는 방법을 제공하는 것이다.The object of the present invention is to provide a method for producing an aramid fiber for reinforcing an automobile part material having excellent impact resistance and excellent compatibility with a polypropylene resin which is widely used as a thermoplastic resin for automobile materials but has no reactor on its surface will be.
본 발명의 또 다른 과제는 자동차 부품 소재의 경량화와 파손강도를 향상시킬 수 있는 자동차 부품 소재 강화용 아라미드 섬유를 제조하는 방법을 제공하는 것이다.
A further object of the present invention is to provide a method for manufacturing aramid fibers for reinforcing automobile parts materials which can improve the weight and breakage strength of automobile parts.
이와 같은 과제를 달성하기 위해서, 본 발명에서는 아라미드 섬유 표면을 (ⅰ) 윤활제, 유화제, 대전 방지제 및 에폭시 성분을 포함하며, (ⅱ) 상기 에폭시 성분의 함량이 30~55중량%인 유제로 처리하여 자동차 부품소재 강화용 아라미드 섬유를 제조한다.In order to achieve the above object, the present invention provides a method for producing an aramid fiber, comprising the steps of (i) providing a lubricant, an emulsifier, an antistatic agent, and an epoxy component; (ii) We manufacture aramid fiber for reinforcing automobile parts material.
본 발명에서는 상기 유제내 에폭시 성분과의 상용성을 좋게하기 위해서 상기 윤활제로 에틸렌 옥사이드(Ethylene oxide)가 부가된 에스테르를 사용한다.
In the present invention, in order to improve the compatibility with the epoxy component in the emulsion, an ester to which ethylene oxide is added as the lubricant is used.
본 발명으로 제조된 자동차 부품 소재 강화용 아라미드 섬유는 내충격성이 우수함과 동시에 자동차 부품 소재용 열가소성 수지로 널리 사용되고 있으나 표면에 반응기가 없는 폴리프로필렌 수지와의 상용성 및 접착력을 향상시키는 계면 특성을 구비하기 때문에 자동차 범퍼, 자동차 백빔 등과 같은 자동차 부품소재 강화용 섬유로 사용시 최종제품인 자동차 부품소재의 경량화는 물론 파손강도를 크게 향상시켜 준다.
The aramid fiber for reinforcing automobile parts materials manufactured by the present invention has excellent impact resistance and is widely used as a thermoplastic resin for automobile parts. However, it has an interfacial property improving compatibility with a polypropylene resin having no reactor on its surface and improving adhesion As a result, when used as reinforcing fibers for automotive parts such as automobile bumpers and automobile back beams, the final product, automobile parts, can be lightweight and greatly improve breakage strength.
이하, 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail.

상기 유제내 에폭시 성분의 함량이 30중량% 미만일 경우에는 자동차 부품 소재용 열가소성 수지인 폴리프로필렌 수지와의 상용성 및 접착성이 충분하지 못하게 되고, 55중량%를 초과하는 경우에는 유제의 점성이 너무 높아 공정성이 저하된다.If the content of the epoxy component in the emulsion is less than 30% by weight, compatibility with the polypropylene resin as a thermoplastic resin for automobile parts and adhesiveness will be insufficient. If the content is more than 55% by weight, The fairness is lowered.
상기 유제를 구성하는 윤활제는 에틸렌 옥사이드(Ethylene oxide)가 부가된 에스테르인 것이 상기 에폭시 성분과의 상용성을 향상시키는데 바람직하다.The lubricant constituting the emulsion is preferably an ester to which ethylene oxide is added in order to improve the compatibility with the epoxy component.
상기 에틸렌 옥사이드가 부가된 에스테르의 윤활제는 디 폴리옥시에틸렌 알킬 에테르 디카복실레이트(Di polyoxyethylene alkyl ether di-carboxylate)와 폴리에틸렌글리콜 디-알킬레이트(Polyethylene glycol di-alkylate)를 혼합하는 방법 등으로 제조할 수 있다.The lubricant of the ethylene oxide-added ester may be prepared by a method of mixing Di polyoxyethylene alkyl ether di-carboxylate and polyethylene glycol di-alkylate .
