Description
[산업상 이용분야][Industrial use]
본 발명은 고내충격·고투명 폴리스티렌계 시트에 관한 것으로, 특히 복합재료를 사용하여 T-Die 시트 성형기에서 제조되는 충격강도가 우수하고, 투명성이 매우 우수한 시트용 열가소성 수지 조성물 및 그를 이용한 고내충격·고투명 폴리스티렌계 시트의 제조방법에 관한 것이다.The present invention relates to a high impact and high transparency polystyrene sheet, in particular, a thermoplastic resin composition for a sheet having excellent impact strength and excellent transparency, produced in a T-Die sheet molding machine using a composite material, and a high impact and high transparency using the same. A method for producing a polystyrene sheet.
[종래 기술][Prior art]
종래의 시트용 열가소성 수지는 폴리스티렌 단독, 고무 변성 폴리스티렌 단독 또는 폴리스티렌과 고무 변성 폴리스티렌의 블렌딩 제품이 주로 사용되었으나, 폴리스티렌의 단독 사용은 투명성은 우수하나 충격강도가 약해 제품 성형시나 보관시 파손되기 쉬웠으며, 고무 변성 폴리스티렌 단독 또는 폴리스티렌과 고무 변성 폴리스티렌의 블렌딩 제품은 충격강도는 우수하나 투명성이 떨어지는 문제점을 안고 있었다.In the conventional thermoplastic resin sheet, polystyrene alone, rubber-modified polystyrene alone, or a blended product of polystyrene and rubber-modified polystyrene is mainly used. However, polystyrene alone is excellent in transparency but weak in impact strength, and thus easily damaged during molding or storage. The rubber-modified polystyrene alone or the blended product of polystyrene and rubber-modified polystyrene had a problem of excellent impact strength but poor transparency.
한편, 스티렌-부타디엔 블록공중합체는 충격강도 및 투명성은 우수하나 인장강도 등의 기계적 물성이 나쁜 문제점을 안고 있었으며, 스티렌-부타디엔 블록공중합 고무의 단독 사용은 충격강도는 우수하나 투명성이 매우 떨어지고 인장강도 등의 기계적 물성이 매우 낮으며, 시트로의 성형성이 나빠서 적용되지 못하고 있었다.On the other hand, styrene-butadiene block copolymers had excellent impact strength and transparency, but had poor mechanical properties such as tensile strength. The use of styrene-butadiene block copolymer rubber alone had excellent impact strength but very low transparency and tensile strength. The mechanical properties of the back and the like were very low, and the moldability to the sheet was poor and thus could not be applied.
본 발명은 상기 종래기술의 문제점을 고려하여, 충격강도 및 인장강도 등의 기계적 물성이 양호하면서 또한 투명성이 매우 우수한 시트용 수지 조성물을 제공하는 것을 목적으로 한다.In view of the problems of the prior art, an object of the present invention is to provide a resin composition for sheets having excellent mechanical properties such as impact strength and tensile strength and excellent transparency.

를 포함하는 고내충격·고투명 시트용 열가소성 수지 조성물 및 이를 이용한 고내충격·고투명 시트의 제조방법을 제공한다.It provides a thermoplastic resin composition for high impact and high transparency sheet and a method of producing a high impact and high transparency sheet using the same.
이하에서 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
[작 용][Action]
본 발명은 투명성은 우수하나 충격강도가 떨어지는 문제, 충격강도는 우수하나 투명도가 저하되는 문제 또는 시트로의 성형성이 저하되는 문제 등의 다양한 상황하를 고려하여 충격강도 및 인장강도 등의 기계적 물성이 양호하면서도 투명성이 매우 우수한 시트용 수지 조성물을 폴리스티렌, 고무 변성 폴리스티렌, 스티렌-부타디엔 블록공중합체, 및 스티렌-부타디엔 블록공중합 고무의 혼합에 의하여 얻게 한 것이다.The present invention has excellent mechanical properties such as impact strength and tensile strength in consideration of various situations such as excellent transparency but low impact strength, excellent impact strength but low transparency or poor formability to sheet. This good resin composition for sheet having excellent transparency is obtained by mixing polystyrene, rubber-modified polystyrene, styrene-butadiene block copolymer, and styrene-butadiene block copolymer rubber.
이를 위하여 상기 폴리스티렌은 용융지수가 200 ℃에서 5 ㎏의 추를 걸어둔 상태에서 10 분에 2 내지 9 g인 것을 사용하는 것이 바람직하며, 조성물 내 함량은 5∼60 중량%으로 하는 것이 좋다. 더욱 바람직하게는 15∼55 중량%이다. 폴리스티렌의 함량이 5 중량% 미만이면 시트의 강성이 부족하여 압공성형, 진공성형 등의 후가공이 어려워지고, 60 중량% 이상이면 충격강도가 약해진다.To this end, it is preferable to use the polystyrene having a melt index of 2 to 9 g in 10 minutes in a state of hanging a weight of 5 kg at 200 ℃, the content of the composition is preferably 5 to 60% by weight. More preferably, it is 15-55 weight%. If the polystyrene content is less than 5% by weight, the rigidity of the sheet is insufficient, so that post-processing such as pressure forming and vacuum forming is difficult. If the content is 60% by weight or more, the impact strength is weakened.
고무 변성 폴리스티렌은 고무함량이 4∼15 중량%를 함유하며 고무 분산형태가 0.5∼2 ㎛크기인 코어-셀 구조 및 캡슐 구조를 갖는 수지로, 용융지수가 200 ℃에서 5 ㎏의 추를 걸어둔 상태에서 10 분에 3 내지 12 g 인 것을 사용하는 것이 바람직하며, 조성물 내 함량은 1∼15 중량%으로 하는 것이 좋다. 더욱 바람직하게는 3∼10 중량%이다. 고무 변성 폴리스티렌은 고무 크기가 작은 것을 사용하는 것이 보다 바람직하다. 고무 변성 폴리스티렌을 전혀 사용하지 않으면 충경강도 및 인장강도를 향상시킬 수가 없으며, 15 중량% 이상 고무 변성 폴리스티렌을 사용하게되면 투명성이 매우 열악해지는 문제가 있다.Rubber modified polystyrene is a resin having a core-cell structure and a capsule structure containing 4 to 15% by weight of rubber and having a rubber dispersion of 0.5 to 2 µm, and having a melt index of 5 kg at 200 ° C. It is preferable to use 3-12 g in 10 minutes in a state, and the content in the composition is preferably 1 to 15% by weight. More preferably, it is 3-10 weight%. As the rubber-modified polystyrene, it is more preferable to use a rubber having a small size. If the rubber-modified polystyrene is not used at all, the hardness and tensile strength cannot be improved, and if the rubber-modified polystyrene is used at least 15% by weight, transparency is very poor.
스티렌-부타디엔 블록공중합체는 스티렌 함유량이 65∼85 중량%, 부타디엔 함유량이 15∼35 중량%로 이루어진 수지로, 용융지수가 200 ℃에서 5 ㎏의 추를 걸어둔 상태에서 10 분에 2 내지 10 g인 것을 사용하는 것이 바람직하며, 조성물 내 함유량은 15∼65 중량%으로 하는 것이 좋다. 더욱 바람직하게는 25∼55 중량%이다. 스티렌-부타디엔 블록공중합체 함량이 15 중량% 미만이면 충격강도가 저하되는 문제를 일으키며, 65 중량%이상 사용하게 되면 인장강도가 떨어져 후가공이 어려워지게 된다.Styrene-butadiene block copolymer is a resin consisting of 65 to 85% by weight of styrene and 15 to 35% by weight of butadiene, and has a melt index of 2 to 10 in 10 minutes with a weight of 5 kg at 200 ° C. It is preferable to use what is g, and it is good to set content in a composition to 15 to 65 weight%. More preferably, it is 25 to 55 weight%. If the styrene-butadiene block copolymer content is less than 15% by weight, the impact strength is lowered. If the styrene-butadiene block copolymer content is used at more than 65% by weight, the tensile strength is lowered, making it difficult to process.
스티렌-부타디엔 블록공중합 고무는 스티렌 함유량이 20∼40 중량%, 부타디엔 함유량이 60∼80 중량%로 이루어진 고무로, 스티렌과 부타디엔의 구조가 리니어 구조와 래디알 구조 모두 사용할 수 있으나 래디알 구조가 보다 바람직하며, 용융지수가 200 ℃에서 5 ㎏의 추를 걸어둔 상태에서 10 분에 0.5 내지 10 g사이에 있으며, 함량은 5~30 중량%이다. 더욱 바람직한 함량은 7∼20 중량%이다. 스티렌-부타디엔 블록공중합 고무 함량이 5 중량% 미만이면 시트의 내충격성이 저하되고, 30 중량% 이상이면 시트의 성형성이 나빠지고 투명성이 저하되며 인장강도 등의 기계적 물성이 열악해 진다.Styrene-butadiene block copolymer rubber is a rubber composed of 20 to 40% by weight of styrene and 60 to 80% by weight of butadiene.The structure of styrene and butadiene can be used in both linear and radial structures. Preferably, the melt index is between 0.5 and 10 g in 10 minutes with a weight of 5 kg at 200 ° C., and the content is 5 to 30% by weight. More preferred content is 7-20% by weight. If the styrene-butadiene block copolymer rubber content is less than 5% by weight, the impact resistance of the sheet is lowered. If the content of the styrene-butadiene block copolymer is lower than 30% by weight, the formability of the sheet is poor, transparency is lowered, and mechanical properties such as tensile strength are deteriorated.
