Description
본 발명은 높은 유동특성을 가짐으로써 자동차의 도어 트림 판넬(Door Trim Panel), 인스트루먼트 판넬(Instrument Panel)등과 같은 대형 내장부품의 표피제로 적합한 열가소성 수지 조성물에 관한 것이다. The present invention relates to a thermoplastic resin composition having high flow characteristics, which is suitable for the skin of large interior parts such as door trim panels, instrument panels, etc. of automobiles.
자동차 내장소재의 고급스러운 느낌을 표현하기 위하여 PPF 또는 PC/ABS로 이루어진 수지 조성물을 사출한 후, 여러공정을 거쳐서 만들어진 표피제를 접착하거나 덧씌움으로써, 감성품질을 높인 도어 트림 판넬이나 인스트루먼트 판넬 등이 사용 되고 있다. 그러나, 이러한 공정은 공정이 복잡하며 제품의 단가가 상승하는 문제점이 있어 일부의 고급 차종에만 적용 가능하다. 하지만 현재의 소비자들은 감성품질을 중요시하기 때문에 고급차종뿐만 아니라 일반 차량에서도 이러한 고급스러움을 요구하고 있다. 따라서 공정을 단순화시켜 제품 단가를 낮추어 일반차량에도 적용 가능하며, 고급소재의 느낌을 표현할 수 있는 소재 기술 개발의 필요성이 점차 증가하고 있다.In order to express the luxurious feeling of automobile interior materials, resin compositions made of PPF or PC / ABS are injected, and then the skin trimming and coating are made by attaching or coating the skin material made through various processes to enhance the sensitivity of door trim panels or instrument panels. This is being used. However, this process is a complicated process and there is a problem that the price of the product rises, it is applicable only to some high-end models. However, current consumers are demanding such a luxury not only luxury cars but also because of the importance of emotional quality. Therefore, the need to develop a material technology that can express the feeling of high-quality materials, which can be applied to general vehicles by simplifying the process and lowering the product cost.
기존에 개발된 부분 가교된 열가소성 탄성체 및 완전 가교된 열가소성 탄성체를 적용할 경우 유동 흐름성이 매우 낮아 대형사출물 위에 이중사출을 하는 것이 쉽지 않다. 이들을 이용하여 이중사출을 시도할 경우 사출이 되었다 하더라도, 미성형(short Shot)이나 유동흐름자국(Flow mark)이 발생하여 도어트림 판넬이나 인스트루먼트 판넬에 적용하기 어려운 점이 있다. 또한 기존에 개발된 고유동 특성을 갖는 폴리올레핀 수지를 적용하여 이중 사출할 경우 제품의 경도가 높아 고급스럽고, 부드러운 느낌을 표현하기 어려운 문제점이 있다.When the partially developed crosslinked thermoplastic elastomer and the fully crosslinked thermoplastic elastomer are applied, the flow flowability is very low, so that double injection over a large injection molding is not easy. Even if the injection is attempted using these, even if the injection is made, it is difficult to apply to the door trim panel or the instrument panel because a short shot or a flow mark is generated. In addition, when the double injection by applying a polyolefin resin having a high flow characteristics developed in the existing high hardness, there is a problem that it is difficult to express a luxurious, soft feeling.

In this regard, US Pat. No. 6,207,754 relates to a thermoplastic olefin composition which is applicable to automotive interior skin preparations, comprising: (A) 40 to 60% by weight of impact modified polypropylene resin (B) 87 to 97.5 mol% 10 to 70% by weight (C) of a separate olefin copolymer elastomer having a density of 0.865 to 0.920 g / cc and a weight average molecular weight of 70,000 or more (C) a coupling agent and an activator compound It includes, and proposes a resin composition having a melt index of 0.5 ~ 5g / 10min of the thermoplastic olefin composition thus prepared. The thermoplastic olefin composition is a resin composition for calendering, and has a low melt flowability, so when it is applied to a double injection of a large product requiring high flow flowability for the skin agent, an unmolded or flow mark is generated and applied. it's difficult.

However, the composition is not suitable as a double injection material for the skin material such as door trim panel or instrument panel of the automobile because it is difficult to express a soft and luxurious feeling due to the lack of rubber content showing soft properties.
본 발명은, 상기와 같은 종래 기술의 문제를 해결하여, 대형물위에 이중 사출이 가능하도록 높은 용융 흐름 특성을 가지면서도 부드러운 질감 및 유연성을 나타내며, 또한, 이중사출의 단일공정에 의하여 제품을 완성할 수 있기 때문에 매우 경제적인 열가소성 수지 조성물을 제공하는 것을 그 목적으로 한다.The present invention solves the problems of the prior art as described above, exhibits a smooth texture and flexibility while having a high melt flow characteristics to enable double injection on a large water, and also complete the product by a single process of double injection.

본 발명은 열가소성 수지의 가교도 및 유동특성을 제어함으로써 높은 유동 흐름특성을 갖도록하여 우수한 사출 성형성과 부드러운 질감의 유연성을 가지는 열가소성 수지를 제공한다. The present invention provides a thermoplastic resin having excellent injection moldability and soft texture flexibility by controlling the crosslinking degree and flow characteristics of the thermoplastic resin to have high flow flow characteristics.
또한, 기존의 사출형 제품은 표피재 제작(1), 사출품 성형(2), 접합(3)의 3단계 공정을 통하여 제조되었으나, 본 발명의 열가소성 수지 조성물을 사용하면 이중사출의 단일공정에 의하여 제품을 완성할 수 있기 때문에 공정 단축으로 인하여 기존품 대비 약 40%의 원가절감의 효과를 얻을 수 있다.In addition, the conventional injection-molded product was manufactured through a three-step process of skin material production (1), injection molding (2), and bonding (3), but using the thermoplastic resin composition of the present invention in a single process of double injection As the product can be finished, the cost can be reduced by 40% compared to the existing product due to the shortening of the process.
