본 발명은 폴리에스테르계 얼로이 수지 조성물에 관한 것으로서, 보다 상세하게는 폴리에스테르계 수지 조성물에 저광택의 아크릴로니트릴-부타디엔-스티렌 공중합체를 첨가하여 내열성 및 충격강도 등의 각종 물성은 향상시키고 소재의 광택은 낮춤으로써 자동차의 내·외장재로서 저광택을 요구하는 플라스틱 부품의 재료로 유용한 폴리에스테르계 얼로이 수지 조성물에 관한 것이다.The present invention relates to a polyester-based alloy resin composition, and more particularly, by adding a low-gloss acrylonitrile-butadiene-styrene copolymer to the polyester-based resin composition to improve various physical properties such as heat resistance and impact strength and The gloss of the present invention relates to a polyester-based alloy resin composition useful as a material for plastic parts requiring low gloss as an interior and exterior material of automobiles.

자동차용 아웃도어 핸들(out door handle, 일명 아웃사이드 핸들)은 알루미늄 다이캐스팅(A1-Die Casting) 후 도금한 것, 아크릴로니트릴-부타디엔-스티렌 공중합체/폴리카보네이트 수지로 성형한 후 도금 또는 무광 도장한 것, 폴리카보네이트/폴리부틸렌테레프탈레이트 수지로 성형한 후 무광 도장한 것 등이 있다. 이중 폴리카보네이트/폴리부틸렌테레프탈레이트 수지는 물성이 우수하며 성형작업성이 좋기 때문에 주로 사용되고 있다.Automotive outdoor door handle (also known as outside handle) is plated after aluminum die casting (A1-Die Casting), plated or coated with acrylonitrile-butadiene-styrene copolymer / polycarbonate resin And a matte coating after molding from polycarbonate / polybutylene terephthalate resin. Dual polycarbonate / polybutylene terephthalate resin is mainly used because of its excellent physical properties and good molding workability.

그런데, 최근 자동차의 원감절감 및 환경보호에 대한 요구가 증가함에 따라 성형후 도장 작업을 생략할 수 있도록 새로운 저광택의 재료 개발의 필요성이 대두 되고 있다.However, in recent years, as the demand for reducing the environment and environmental protection of automobiles increases, there is a need for developing a new low-gloss material to omit post-molding work.

저광택의 폴리에스테르계 수지를 얻고자 유럽특허 EP 622416 A2 941102에서 는 폴리메틸메티크릴레이트-폴리부타디엔-스티렌 고무와 글리시딜 메타크릴레이트-메틸메타크릴레이트-스티렌 공중합체를 사용하였으며, 유럽특허 EP 369200 A2 900523에서는 폴리카보네이트/스티렌-아크릴로니트릴 공중합체의 혼합물에 아크릴로니트릴-스티렌-그라프트 실록산(grafted siloxane)을 첨가하는 방법이 소개되어 있다.In European Patent EP 622416 A2 941102, polymethylmethacrylate-polybutadiene-styrene rubber and glycidyl methacrylate-methylmethacrylate-styrene copolymer were used to obtain a low-gloss polyester resin. EP 369200 A2 900523 describes a method for adding acrylonitrile-styrene-grafted siloxane to a mixture of polycarbonate / styrene-acrylonitrile copolymers.

그러나 상기와 같은 종래의 발명들은 광택도를 낮추는 효과는 있으나 실용화에는 한계가 있었으며, 현재까지 폴리카보네이트/폴리부틸렌테레프탈레이트 얼로 이 수지의 광택도를 낮추기 위한 사례 또는 발명은 소개되지 않고 있다.However, the above-described conventional inventions have an effect of lowering the glossiness, but have limitations in practical use, and thus, no case or invention for reducing the glossiness of the polycarbonate / polybutylene terephthalate alloy has been introduced.

이에, 본 발명자들은 자동차 아웃도어 핸들용의 저광택 수지를 개발하기 위하여 연구를 계속하여 오던 중, 기존의 폴리카보네이트/폴리부틸렌테레프탈레이트 수지에 저광택의 아크릴로니트릴-부타디엔-스티렌 공중합체를 첨가함으로써 광택도를 낮춘 본 발명의 수지 조성물을 개발하여 본 발명을 완성하였다.Accordingly, the present inventors have continued to research to develop a low-gloss resin for automobile outdoor handles, and by adding a low-gloss acrylonitrile-butadiene-styrene copolymer to an existing polycarbonate / polybutylene terephthalate resin The present invention was completed by developing the resin composition of the present invention having a lowered glossiness.

[발명이 이루고자 하는 기술적 과제][Technical problem to be achieved]

본 발명의 목적은 폴리에스테르계 얼로이 수지의 광택도를 낮춤으로써 무광도장이 필요없는, 자동차의 아웃도어 핸들의 소재를 비롯한 기타 저광택을 요구하는 플라스틱 부품의 소재로 사용할 수 있는 폴리에스테르계 얼로이 수지 조성물을 제공하는 것이다.An object of the present invention is to reduce the glossiness of polyester alloy resins, which can be used as a material for plastic parts that require low gloss, including materials for automobile outdoor handles, which do not require matt coating, and are used as polyester alloy resins. It is to provide a resin composition.

[발명의 구성 및 작용][Configuration and Function of Invention]

상기 목적을 달성하기 위하여 본 발명에서는 폴리카보네이트/폴리부틸렌테레프탈레이트 수지, 충격보강제 및 첨가제인 아크릴로니트릴-부타디엔-스티렌 공중합체로 구성되는 폴리에스테르계 얼로이 수지 조성물을 제공한다.In order to achieve the above object, the present invention provides a polyester-based alloy resin composition composed of a polycarbonate / polybutylene terephthalate resin, an impact modifier and an acrylonitrile-butadiene-styrene copolymer.

이하 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

본 발명의 폴리에스테르계 수지 조성물은 폴리카보네이트 30∼90 중량%, 폴리부틸렌테레프탈레이트 10∼60 중량%, 충격보강제 0∼30 중량% 및 첨가제인 저광택의 아크릴로니트릴-부타디엔-스티렌 공중합체 3∼20 중량%로 이루어져 있다.The polyester resin composition of the present invention is 30 to 90% by weight polycarbonate, 10 to 60% by weight polybutylene terephthalate, 0 to 30% by weight impact modifier and low-gloss acrylonitrile-butadiene-styrene copolymer 3 It consists of -20 weight%.

본 발명은 저광택의 아크릴로니트릴-부타디엔-스티렌 공중합체를 첨가하여 이루어진 폴리에스테르계 얼로이 수지 조성물에 관한 것으로서, 본 발명의 조성물 중 주성분인 폴리에스테르계 수지의 구체적인 화합물은 폴리카보네이트 및 폴리부틸렌테레프탈레이트이다.The present invention relates to a polyester-based alloy resin composition formed by adding a low-gloss acrylonitrile-butadiene-styrene copolymer, wherein specific compounds of the polyester-based resin as a main component of the composition of the present invention are polycarbonate and polybutylene Terephthalate.

폴리카보네이트의 종류는 용융지수(MI-MFR)로 특징짓는데, 대략적인 범위는 용융지수가 1∼30 g/10분인 것이 적당하며. 2∼20 g/10분이 바람직하다. 폴리카보네이트의 용융지수가 1 g/10분 미만인 것을 사용하면 유독성이 좋지 못하여 성형성이 떨어지고, 30 g/10분을 초과하면 충격강도가 떨어지는 문제점이 있다. 이와 같은 용융지수를 가지는 폴리카보네이트를 전체 수지 중 30∼90 중량% 첨가하는데, 50∼80 중량%를 첨가하는 것이 보다 바람직하다.The type of polycarbonate is characterized by a melt index (MI-MFR), the approximate range being 1-30 g / 10 minutes. 2-20 g / 10 minutes are preferable. If the melt index of the polycarbonate is less than 1 g / 10 minutes, the toxicity is not good, the moldability is lowered, if it exceeds 30 g / 10 minutes, there is a problem that the impact strength falls. Although 30-90 weight% of polycarbonate which has such a melt index is added to all resin, it is more preferable to add 50-80 weight%.

또다른 주성분인 폴리부틸렌테레프탈레이트의 종류는 용융점도(MV)로 특징짓는데, 대략적인 범위는 용융점도가 500∼10000 Poise인 것이 적당하며, 1000∼8000 Poise 인 것이 바람직하다. 이와 같은 용융지수를 가지는 폴리부틸렌테레프탈레이트를 전체 수지 조성중 10∼60 중량% 첨가하는데, 15∼45 중량% 첨가하는 것이 바람직하다.The other main component, polybutylene terephthalate, is characterized by a melt viscosity (MV). The approximate range is preferably from 500 to 10,000 Poise, preferably from 1000 to 8000 Poise. Although 10-60 weight% of polybutylene terephthalates which have such a melt index are added in the whole resin composition, it is preferable to add 15-45 weight%.

한편 충격보강제는 주로 수지조성물의 내충격성을 높이기 위해 첨가되는 것으로 통상의 것을 첨가할 수 있는데, 예를 들어 에틸렌-프로필렌 고무, 메틸메타크릴레이트-부타디엔-스티렌 공중합체, 부틸아크릴레이트-메틸메타크릴레이트 공중합체, 스티렌-부타디엔-스티렌 공중합체, 폴리에스테르계 블록 공중합체, 개질 에틸렌-프로필렌 공중합체, 에틸렌-에틸아크릴레이트 공중합체 중에서 단독 또는 2종 이상의 혼합물을 사용할 수 있다. 바람직하기로는 메틸메타크릴레이트-부타디엔-스티렌 공중합체, 부틸아크릴레이트-메틸메타크릴레이트 공중합체, 폴리에스테르계 블록 공중합체를 사용하는 것이 좋다. 상기와 같은 충격보강제를 통상적으로 수지 전체 조성 중 0∼30 중량% 첨가하는데, 5∼25 중량%를 첨가하는 것이 바람직하다. 한편 본 발명에서는 별도의 충격보강제를 첨가하지 않고 저광택의 아크릴로니트릴-부타디엔-스티렌 공중합체만을 첨가함으로써 수지의 광택을 낮춤과 동시에 내충격성도 유지하게 할 수 있다.On the other hand, the impact modifier is mainly added to increase the impact resistance of the resin composition can be added to the conventional one, for example, ethylene-propylene rubber, methyl methacrylate-butadiene-styrene copolymer, butyl acrylate-methyl methacryl A single or a mixture of two or more of the rate copolymer, the styrene-butadiene-styrene copolymer, the polyester block copolymer, the modified ethylene-propylene copolymer, and the ethylene-ethylacrylate copolymer can be used. Preferably, a methyl methacrylate-butadiene-styrene copolymer, a butyl acrylate-methyl methacrylate copolymer, or a polyester block copolymer is preferably used. Although the above-mentioned impact modifier is usually added in an amount of 0 to 30% by weight in the total resin composition, it is preferable to add 5 to 25% by weight. On the other hand, in the present invention, by adding only a low-gloss acrylonitrile-butadiene-styrene copolymer without adding a separate impact modifier, the gloss of the resin can be lowered and impact resistance can be maintained.

본 발명에서 특징적으로 첨가되는 저광택의 아크릴로니트릴-부타디엔-스티렌 공중합체는 수지의 기계적 물성을 유지시키면서 수지의 광택도를 대폭적으로 낮출 수 있는 우수한 첨가제이다. 이와 같은 저광택의 아크릴로니트릴-부타디엔-스티렌 공중합체를 전체 수지 조성 중 3∼20 중량% 첨가하는데, 그 함량이 이 범위를 벗어나면 수지의 광택도를 낮추기 어렵거나 수지의 기계적 물성의 변화의 폭이 커진다.The low gloss acrylonitrile-butadiene-styrene copolymer added in the present invention is an excellent additive that can drastically lower the glossiness of the resin while maintaining the mechanical properties of the resin. The low gloss acrylonitrile-butadiene-styrene copolymer is added in an amount of 3 to 20% by weight in the total resin composition. If the content is outside this range, it is difficult to lower the glossiness of the resin or the width of the change in mechanical properties of the resin. Will grow.

그 밖에 본 발명에서는 필요에 따라 각종 첨가제, 예를 들어 산화방지제, 자외선흡수제, 대전방지제, 내후안정제, 활제 및 기핵제 등을 적절히 선택하여 첨가할 수 있다.In addition, in the present invention, various additives such as antioxidants, ultraviolet absorbers, antistatic agents, weathering stabilizers, lubricants and nucleating agents may be appropriately selected and added as necessary.

상기와 같은 본 발명의 수지 조성물로 합성수지를 제조하는 경우, 그 제조방법은 통상적으로 사용되는 장치 및 방법을 이용하여 제조할 수 있다. 즉, 필요성분을 혼합하고, 그 혼합물을 성형 펠렛이 형성되도록 단스크류 또는 쌍스크류 압출기를 사용하여 반죽하고, 경우에 따라서는 필요한 성분들 일부를 마스터 배치(master batch)로 다른 성분들과 혼합하고, 그 혼합물을 성형하는 방법도 사용할 수 있다.When manufacturing a synthetic resin with the resin composition of the present invention as described above, the production method can be produced using a conventionally used apparatus and method. That is, the necessary ingredients are mixed, the mixture is kneaded using a single screw or twin screw extruder to form a molding pellet, and optionally some of the necessary ingredients are mixed with other ingredients in a master batch. And a method of molding the mixture can also be used.

상기 표 1에서 볼수 있듯이, 본 발명의 폴리에스테르계 얼로이 수지 조성물은 저광택의 아크릴로니트릴-부타디엔-스티렌 공중합체를 첨가하지 않은 비교예의 조성물과 비교하여 광택도는 현저히 낮아졌으며 굴곡탄성율 및 열변형온도 등의 물성은 향상되었거나 유지되었음을 알 수 있다.As can be seen in Table 1, the polyester-based alloy resin composition of the present invention is significantly lower gloss compared to the composition of the comparative example without the addition of low-gloss acrylonitrile-butadiene-styrene copolymer, flexural modulus and heat deformation It can be seen that physical properties such as temperature have been improved or maintained.

[발명의 효과][Effects of the Invention]

상기에서 볼 수 있는 바와 같이, 저광택의 아크릴로니트릴-부타디엔-스티렌 공중합체를 첨가한 본 발명의 폴리에스테르계 얼로이 수지 조성물은 종래의 폴리에스테르계 수지에 비하여 광택도는 크게 낮추면서 각종 물성은 향상되거나 유지됨으로써 자동차용 아웃도어 핸들 등의 부품 제조시 무광을 위한 도장 과정을 생략할 수 있다. 따라서 본 발명의 조성물을 이용하여 부품을 제조하면 도장 과정이 생략되어 원가를 절감할 수 있을 뿐만 아니라 환경오염을 방지하는데도 기여할 수 있으므로, 본 발명의 폴리에스테르계 얼로이 수지 조성물은 자동차의 아웃도어 핸들의 소재 및 기타 저광택을 요구하는 플라스틱 부품의 소재로 유용하게 사용될 수 있다.As can be seen from the above, the polyester-based alloy resin composition of the present invention to which a low-gloss acrylonitrile-butadiene-styrene copolymer is added is significantly lowered in glossiness compared to conventional polyester resins, and has various physical properties. By being improved or maintained, it is possible to omit the coating process for matting in manufacturing parts such as automotive outdoor handles. Therefore, when manufacturing a part using the composition of the present invention, the coating process is omitted, not only can reduce the cost, but also contribute to preventing environmental pollution, the polyester-based alloy resin composition of the present invention is an outdoor handle of a vehicle It can be usefully used as a material for plastic parts requiring low gloss and other materials.
