It provides excellent light resistance with a relatively strong structure, and gives excellent impact characteristics by reinforcing a silicone-based impact reinforcement with excellent low temperature impact to strengthen the impact, and makes a slight shrinkage deviation of the surface of a molded product by using a gloss reducing agent. Its surface gloss is lowered, and UV absorbers are added to it, so it has excellent molding processability and dimensional stability, and maintains excellent properties such as heat resistance and low temperature impact strength. Especially, it has no coating, low glossiness, and light resistance. Polycarbo which can be used very well Byte relates to a resin composition.

종래에는 수지의 표면 광택을 낮추는 제조방법 중에는 에멀젼 중합법으로 제조되는 아크릴로니트릴-부타디엔-스티렌 중합체에 개질제로 에틸렌-불포화카르복실산과 같은 단량체를 그라프트 중합하는 방법이 있다. 상기 방법으로 제조된 수 지는 저광택성이 양호하여 아크릴로니트릴-부타디엔-스티렌 중합체에는 효과적이지만, 비슷한 구조식을 갖는 아크릴로니트릴-스티렌-아크릴레이트 수지와 같은 수지에 적용할 경우 내광성이 저하되는 문제점이 발생한다. 따라서 저광택성과 내광성이 우수한 아크릴로니트릴-스티렌-아크릴레이트 소재개발에는 많은 어려움이 있었다.Conventionally, among the production methods for lowering the surface gloss of the resin, there is a method of graft polymerization of a monomer such as ethylene-unsaturated carboxylic acid as a modifier to an acrylonitrile-butadiene-styrene polymer produced by the emulsion polymerization method. The resin prepared by the above method is effective in acrylonitrile-butadiene-styrene polymer due to its low glossiness, but the problem of lowering light resistance when applied to a resin such as acrylonitrile-styrene-acrylate resin having a similar structural formula Occurs. Therefore, there have been many difficulties in developing acrylonitrile-styrene-acrylate material having excellent low gloss and light resistance.

한편 폴리카보네이트와 아크릴로나이트릴-스타이렌-아크릴레이트고무, 가교형 스타이렌-아크릴로나이트릴, 그리고 실리콘계 충격보강제를 사용하여 우수한 충격 특성 및 내광성을 가지는 저광택도 폴리카보네이트 수지 조성물에 대한 특허를 출원된 바 있으나, 해당 조성물은 무도장 제품의 적용에 필수적인 내광성이 충분하지 못하여 변색이 발생하는 단점이 있다. 특히 이러한 내광성이 부족한 문제는 칼라가 일치되어야 하는 자동차 내장재 부품의 이색감을 유발하는 문제를 지니고 있어 적용이 어려운 문제점이 발생 하였다.Meanwhile, a patent for a low gloss polycarbonate resin composition having excellent impact characteristics and light resistance by using polycarbonate and acrylonitrile-styrene-acrylate rubber, crosslinked styrene-acrylonitrile, and silicone-based impact modifiers Although it has been filed, the composition has a disadvantage in that discoloration occurs due to insufficient light resistance essential for the application of an unpainted product. In particular, such a problem that the lack of light resistance has a problem that causes a different color of the interior parts of the car to be matched color has a problem that is difficult to apply.

이에, 본 발명자들은 상기와 같은 내광성의 문제점을 해결하고, 저광택의 폴리카보네이트 아크릴로니트릴-스티렌-아크릴레이트 얼로이를 개발하고자 노력 하였다. Accordingly, the present inventors have tried to solve the above problems of light resistance, and to develop a low-gloss polycarbonate acrylonitrile-styrene-acrylate alloy.

그 결과, 폴리카보네이트 수지에 그라프트 공중합체 (아크릴로니트릴-스티렌-아크릴레이트)와 실리콘계 충격보강재, 및 광택저하제를 최적의 비로 혼합하고, UV 흡수제를 보강하여 저광택성 및 내광성이 향상된 폴리카보네이트 수지를 완성하 였다.As a result, the polycarbonate resin is mixed with a graft copolymer (acrylonitrile-styrene-acrylate), a silicone-based impact modifier, and a gloss reducing agent in an optimum ratio, and a polycarbonate resin having low glossiness and light resistance by reinforcing a UV absorber. Completed.

따라서 본 발명은 저광택성 및 내광성이 향상된 폴리카보네이트 수지를 제공하는데 목적이 있다.Therefore, an object of the present invention is to provide a polycarbonate resin with improved low gloss and light resistance.

이와 같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.

본 발명은 폴리카보네이트 수지에 그라프트 공중합체 (아크릴로니트릴-스티렌-아크릴레이트)와 실리콘계 충격보강재 및 광택저하제를 최적의 비로 혼합하고, 자외선 흡수제를 보강하여, 성형가공성과 치수 안정성이 뛰어나며, 내열성 및 저온충격강도 등의 우수한 특성을 유지하고, 무도장, 저광택성을 지니며, 내광성이 보강된 폴리카보네이트 수지 조성물에 관한 것이다.The present invention mixes a graft copolymer (acrylonitrile-styrene-acrylate), a silicone-based impact modifier and a gloss-lowering agent in an optimal ratio, reinforces the ultraviolet absorber, and has excellent moldability and dimensional stability, and heat resistance. And a polycarbonate resin composition having excellent properties such as low temperature impact strength, having no coating, low glossiness, and enhanced light resistance.

이러한 본 발명의 폴리카보네이트 수지 조성물의 각 구성 성분에 대하여 보다 구체적으로 설명하면 다음과 같다.The components of the polycarbonate resin composition of the present invention will be described in more detail as follows.

본 발명에서 사용되는 폴리카보네이트는 5 ~ 40 g/10 분(300℃, 2.16kg) 인 것이 바람직하며 용융지수가 5 g/10 분 미만이면 성형성 저하로 인해 미성형이 발생하거나, 동일 제품 내 광택도 차이를 유발하게 되며, 40 g/10 분 초과 시 폴리카보네이트의 낮은 분자량으로 우수한 기계적 강도를 가질 수 없다. The polycarbonate used in the present invention is preferably 5 ~ 40 g / 10 minutes (300 ℃, 2.16kg) and if the melt index is less than 5 g / 10 minutes, unmolding occurs due to deterioration of moldability, or in the same product The glossiness difference will be caused, and the low molecular weight of the polycarbonate may not have good mechanical strength above 40 g / 10 minutes.

상기 폴리카보네이트의 경우, 전체 폴리카보네이트 아크릴로니트릴-스티렌-아크릴레이트 얼로이 수지 조성물에 대하여, 37 ~ 90 중량%, 바람직하기로는 50 ~ 70 중량% 범위로 사용하며 이때, 상기 함량이 37 중량% 미만이면 아크릴로니트릴-스티렌-아크릴레이트 그라프트 공중합체 매트릭스의 형성하는 문제점으로 우수한 충격강도를 가질 수 없는 문제점이 발생하여 바람직하지 못하다. 90 중량% 이상의 경우 내광성이 취약해지는 문제가 발생한다.In the case of the polycarbonate, the total polycarbonate acrylonitrile-styrene-acrylate alloy resin composition is used in the range of 37 to 90% by weight, preferably 50 to 70% by weight, wherein the content is 37% by weight If it is less than the problem of forming an acrylonitrile-styrene-acrylate graft copolymer matrix is not preferred because it can not have a good impact strength. If more than 90% by weight causes a problem that the light resistance is weak.

본 발명에서 내광성 그라프트 공중합체는 본 조성물에서 수지 조성물의 충격특성 향상 및 내광성을 부여하며 스티렌계 방향족 비닐 화합물과 아크릴로니트릴계 시안화 비닐화합물이 그라프트된 공중합체 및 아크릴레이트 고무 등 중에서 선택된 1 종 또는 2 종의 내광성 그라프트 공중합체이며 전체 아크릴로니트릴-스티렌-아크릴레이트 수지 조성물에 대하여 함량이 1 ~ 50 중량%, 바람직하기로는 15 ~ 25 중량%가 적당하다. 상기 함량이 1 중량% 미만이면 충격특성 및 내광성 보강 효과가 부족하고, 50 중량%를 초과하면 성형성이 저하되어 균일한 저광택도를 얻기가 어려운 문제점이 발생한다. In the present invention, the light-resistant graft copolymer improves impact properties and light resistance of the resin composition in the present composition and is selected from a copolymer of styrene-based aromatic vinyl compound, acrylonitrile-based vinyl cyanide compound, and acrylate rubber. It is a species or two kinds of light resistant graft copolymers, and the content is 1 to 50% by weight, preferably 15 to 25% by weight based on the total acrylonitrile-styrene-acrylate resin composition. If the content is less than 1% by weight, the impact properties and light resistance reinforcing effect is insufficient, and if the content exceeds 50% by weight, the moldability is lowered, so that it is difficult to obtain a uniform low gloss.

본 발명의 실리콘계 충격 보강재는 폴리카보네이트 수지 조성물 내에서 외부 충격을 분산 및 흡수하는 역할을 하여 충격 특성을 향상시킨다. 상기 실리콘계 충격보강제는 코어-비닐계쉘 구조를 이루는 것으로 상기 실리콘계 충격 보강재는 함량이 전체 함량에 대하여 3 ~ 7 중량% 범위로 함유되는데, 3 중량% 미만이면 충격 보강 효과가 불충분하고, 7 중량%를 초과하면 수지 조성물의 흐름성을 방해하여 성형성 저하로 균일한 저광택도 구현에 문제점이 발생된다.  The silicone impact modifier of the present invention serves to disperse and absorb external impacts in the polycarbonate resin composition to improve impact characteristics. The silicone-based impact modifier constitutes a core-vinyl-based shell structure, and the silicone-based impact modifier contains a content of 3 to 7% by weight based on the total content. When the silicone-based impact modifier is less than 3% by weight, the impact reinforcing effect is insufficient, and 7% by weight. If exceeded, the flowability of the resin composition may be disturbed, resulting in a problem of achieving uniform low glossiness due to deterioration of moldability.

또한 본 발명에서는 광택저하제가 사용되며 가교된 스티렌아크릴로나이트릴, 에틸렌, 알파메틸스티렌, 파라메틸스티렌, 비닐톨루엔, p-t-부틸스티렌, 및 클로로스티렌 등 중에서 선택된 1종 또는 2종의 혼합물을 사용하며 상기 광택저하제는 전체 조성물 중에서 3 ~ 8 중량% 범위로 사용하며 3 중량% 미만으로 사용 시 충분한 광택 저하 효과를 볼 수 없고, 8 중량% 초과 시 충격 저하의 문제점이 발생한다.In the present invention, a gloss reducing agent is used, and one or two mixtures selected from crosslinked styrene acrylonitrile, ethylene, alphamethylstyrene, paramethylstyrene, vinyltoluene, pt-butylstyrene, and chlorostyrene are used. And the gloss lowering agent is used in the range of 3 to 8% by weight of the total composition and when used in less than 3% by weight can not see a sufficient gloss reduction effect, when more than 8% by weight occurs a problem of impact reduction.

본 발명의 가장 큰 특징으로 기존에 제안된 발명의 단점인 내광성 부족으로 인한 변색발생을 UV 흡수제를 첨가함으로써 개선한 점에 있다. 일반적으로 UV 흡수제는 플라스틱의 열화 개시 인자인 자외선을 흡수하는 것으로 그 첨가에 의한 플라스틱의 내후성은 대폭 개량된다. The biggest feature of the present invention is that the color change caused by the lack of light resistance, which is a disadvantage of the conventionally proposed invention, is improved by adding a UV absorber. In general, the UV absorber absorbs ultraviolet light, which is a deterioration initiation factor of the plastic, and the weatherability of the plastic is greatly improved by the addition thereof.

종래에는 자외선을 거의 흡수하지 않지만 자외선 에너지에 의해 발생하는 유해한 프리래디칼을 효율적으로 보충함에 따라 플라스틱을 안정화하는 핀다이드아민계 UV 안정제(HALS)로 사용되고 있다. 이에 따라 상승효과가 나타나고 우수한 내광성을 보이나, 무도장 용도에 사용되기에는 그 효과가 부족한 면이 있다.Conventionally, it is used as a pinidamine-based UV stabilizer (HALS) that stabilizes plastics because it absorbs little ultraviolet rays but efficiently replenishes harmful free radicals generated by ultraviolet energy. As a result, there is a synergistic effect and excellent light resistance, but the effect is insufficient to be used for unpainted applications.

따라서 본 발명에서는 290 ~ 400 nm의 자외선을 흡수하고 효율이 좋으며, 무 해한 열 에너지로 전환해 분산하는 것으로 동시에 자신은 빛에 대해 안정한 물질인 UV 흡수제로 흡수범위가 자외선 전역에 걸친 흡수능력이 가장 우수한 벤조트리아졸계를 사용하였다. Therefore, the present invention absorbs ultraviolet light of 290 ~ 400 nm and is efficient, and converts into harmless thermal energy to disperse, and at the same time it is a UV absorber which is a stable material against light, its absorption range is wide The best benzotriazole system was used.

특히 본 발명에서는 하이드록시벤조트리아졸계 UV 흡수제를 사용하였으며, 상기 UV 흡수제는 전체 조성물 중에서 0.1 ~ 1.5 중량% 범위로 사용되며 0.1 중량% 미만으로 사용 시 충분한 내광성을 얻을 수 없으며, 1.5 중량% 초과 시 수지 조성물의 기계적 물성 저하 및 과도한 가스 발생으로 성형품 외관에 문제점이 발생한다. 하이드록시벤조트리아졸계 자외선 흡수제는 유기고분자 화합물에 첨가하면 자외선을 선택적으로 흡수하고 무해한 열에너지로 변해 소재의 황변화, 기기적 물성저하 등 열화를 지연시킨다. 특히 PVC, 스티렌계, 폴리에스터계, 아크릴계폴리머, 폴리우레탄, 폴리카보네이트, PVDC, 셀룰로스에스터에 효과가 크며, 금속이온과 특히 알킬성하에서 착염을 형성해 착색하는 것에 주의해야 한다.Particularly, in the present invention, a hydroxybenzotriazole-based UV absorber was used, and the UV absorber is used in the range of 0.1 to 1.5% by weight in the total composition, and when used in less than 0.1% by weight, sufficient light resistance cannot be obtained. Problems occur in the appearance of the molded article due to a decrease in the mechanical properties of the resin composition and excessive gas generation. When hydroxybenzotriazole-based ultraviolet absorber is added to the organic polymer compound, it selectively absorbs ultraviolet rays and turns into harmless thermal energy, which delays deterioration such as yellowing of material and deterioration of mechanical properties. In particular, it is effective in PVC, styrene, polyester, acrylic polymer, polyurethane, polycarbonate, PVDC, and cellulose ester, and care should be taken to form a complex salt under metal ions and especially alkylation to color.

또한, 첨가제로 상기 조성물 외에 산화방지제, 윤활제, 실리콘 조제, 이형제, 안료, 대전방지제, 항균제, 가공조제 및 내마찰 마모제를 소량으로 적절하게 첨가될 수 있다.In addition, as an additive, an antioxidant, a lubricant, a silicone aid, a mold release agent, a pigment, an antistatic agent, an antibacterial agent, a processing aid, and an antifriction wear agent may be appropriately added in a small amount.

상기 조성물의 혼련 방법은 당 분야에서 사용하는 것으로 한정하지 않으나 드라이브렌딩 후 가열 용융 혼련하는 방법을 적용할 수 있고, 온도는 통상 230 ~ 280 ℃ 범위이고 바람직하게는 240 ~ 275 ℃ 범위에서 각 성분이 물리, 화학적으로 충분히 친화력을 유지할 수 있도록 혼련을 행한다. 온도가 230 ℃ 미만이면 수지 조성물이 용융되지 않아 혼련이 불가능 하고, 275 ℃ 를 초과하면 과도한 수지 분해로 인해 제품 물성의 저하를 유발 하므로 상기 범위를 유지해야 한다.The method of kneading the composition is not limited to those used in the art, but a method of heat-melting kneading after drive blending may be applied, and the temperature is usually in the range of 230 to 280 ° C and preferably in the range of 240 to 275 ° C. Kneading is carried out to maintain affinity sufficiently physically and chemically. If the temperature is less than 230 ℃ kneading is impossible because the resin composition is not melted, if the temperature exceeds 275 ℃ due to excessive resin degradation causes product properties should be maintained within the above range.
