본 발명은 데코시트용 폴리프로필렌 수지 조성물에 관한 것으로서, 보다 상세하게는 캘린더링 가공이 가능하며, 유연성 및 연신성이 우수한 데코시트용 폴리프로필렌 수지 조성물에 관한 것이다.The present invention relates to a polypropylene resin composition for decor sheet, and more particularly, to a polypropylene resin composition for decor sheet capable of calendering processing and excellent in flexibility and stretchability.
현재 환경 문제의 대두로, 친환경 건축자재 및 내외장 마감재에 대한 관심이 높아지고 있다. 그 중 데코레이션 시트(이하, 데코시트)는 장롱, 싱크대, 수납장과 같은 가구에 나무 무늬와 같은 장식을 표현하기 위한 시트를 의미하며, 통상 원목이 매우 고가이기 때문에, 재생나무를 이용하여 만들어진 목판에 나무 무늬 및 여러 무늬를 표현하기 위해 사용된다. 현재까지, 이와 같은 데코 시트 재료로 PVC가 이용되었으나, 환경 호르몬을 함유하며, 연소시 다이옥신이 발생하는 문제점이 대두되어, 친환경소재로의 개발 중요성이 점차 고조되고 있다. As the current environmental issues, interest in environmentally friendly building materials and interior and exterior finishing materials is increasing. Among them, a decoration sheet (hereinafter, a decoration sheet) means a sheet for expressing a decoration such as a tree pattern on furniture such as a dresser, a sink, a storage cabinet, and a wooden board made of recycled wood because the wood is usually very expensive. It is used to express wood patterns and various patterns. Until now, PVC has been used as such a deco sheet material, but it contains environmental hormones, and the problem that dioxin occurs during combustion, the importance of development as an environmentally friendly material is gradually increasing.
대부분의 데코시트는 캘린더링(calendering) 공법에 의하여 제조되며, 미국 특허 제4,1444,304호에서는 25~75중량%의 폴리올레핀계 수지를 25~75중량%의 식물성 섬유와 혼합하여 캘린더링 방법을 이용하여 필름 및 시트를 제조하는 방법이 개 시되어 있으며, 미국특허 제5,439,628호에는 폴리프로필렌에 많은 양의 충전제를 첨가하므로써, 캘린더롤의 표면과 용융물 사이의 점착성을 감소시켜 필름 및 시트를 제조하는 방법이 개시되어 있다.Most decor sheets are manufactured by a calendering method, and in US Patent No. 4,1444,304, a calendering method is obtained by mixing 25 to 75% by weight of polyolefin resin with 25 to 75% by weight of vegetable fiber. A method for producing films and sheets using the present invention is disclosed. US Pat. No. 5,439,628 describes the production of films and sheets by adding a large amount of filler to polypropylene, thereby reducing the adhesion between the surface of the calender roll and the melt. A method is disclosed.
한편, 한국특허 제220892호에는 분자량 560,000~1,200,000g/mol인 폴리프로필렌 수지에 고밀도 폴리에틸렌 및 선형저밀도 폴리에틸렌으로 이루어진 수지와 충전제, 실리카겔, 활제 및 안정제를 첨가하여, 데코시트를 제조하는 방법이 개시되어 있다. 그러나 이와 같은 수지 조성물에서는, 사용되는 수지의 유연성 및 연신이 부족하므로 딥 드로잉(deep drawing)시 복잡한 문양의 표현이 어렵다는 단점이 있다. On the other hand, Korean Patent No. 220892 discloses a method for producing a decor sheet by adding a resin, a filler made of high density polyethylene and linear low density polyethylene, a silica gel, a lubricant and a stabilizer to a polypropylene resin having a molecular weight of 560,000 to 1,200,000 g / mol. have. However, in such a resin composition, since the flexibility and stretching of the resin used is insufficient, it is difficult to express complex patterns during deep drawing.
본 발명은 상기와 같은 문제를 해결하기 위한 것으로, 캘린더링 가공이 가능하며, 유연성 및 연신이 우수하여 시트 가공시 백화현상을 없애고, 복잡한 문양의 표현이 가능한 시트 제조에 이용가능한 폴리프로필렌 수지 조성물의 제공을 목적으로 한다. The present invention is to solve the above problems, it is possible to calendering process, excellent flexibility and elongation to eliminate the whitening phenomenon during sheet processing, the polypropylene resin composition which can be used for the production of a sheet capable of expressing complex patterns It is for the purpose of providing.
본 발명의 폴리프로필렌 수지 조성물은, 폴리프로필렌 40~99.8중량%와, 광안정제 0.01~1.0중량%, 산화방지제 0.01~1.0중량%, 촉매잔류물 중화제 0.01~1.0중량%, 충전제 5~50중량%, 블로킹 방지제 0.2~5중량%, 활제 0.1~10중량% 및 핵제 0.05~1.0중량%로 이루어진 군으로부터 선택되는 2종 이상의 첨가제 0.2~60중량%를 포함하여 이루어지는 것을 특징으로 한다.The polypropylene resin composition of the present invention is 40 to 99.9 wt% polypropylene, 0.01 to 1.0 wt% light stabilizer, 0.01 to 1.0 wt% antioxidant, 0.01 to 1.0 wt% catalyst residue neutralizing agent, 5 to 50 wt% filler And 0.2 to 60% by weight of two or more additives selected from the group consisting of 0.2 to 5% by weight of antiblocking agent, 0.1 to 10% by weight of lubricant and 0.05 to 1.0% by weight of nucleating agent.
본 발명의 폴리프로필렌 수지 조성물을 구성하는 상기 폴리프로필렌 수지는에틸렌-프로필렌 랜덤 공중합체, 또는 결정성 에틸렌-프로필렌 랜덤 공중합부분과탄성 에틸렌-프로필렌 블록 공중합부분을 함유하는 에틸렌-프로필렌 랜덤-블록 공중합체인 것이 바람직하다.The polypropylene resin constituting the polypropylene resin composition of the present invention is an ethylene-propylene random copolymer or an ethylene-propylene random-block copolymer containing a crystalline ethylene-propylene random copolymer portion and an elastic ethylene-propylene block copolymer portion. It is preferable.
본 발명에서 폴리프로필렌 수지로서 사용되는 상기 에틸렌-프로필렌 랜덤 공중합체는 용융지수가 0.1~10g/10분인 것이 바람직한데, 0.1g/10분 미만이면 조성물의 성형성이 열세해지고, 10g/10분을 초과하면 충격강도가 급격히 저하되는 문제가 있기 때문이다.In the present invention, the ethylene-propylene random copolymer used as the polypropylene resin preferably has a melt index of 0.1 to 10 g / 10 minutes. If the ethylene-propylene random copolymer is less than 0.1 g / 10 minutes, the moldability of the composition is inferior and 10 g / 10 minutes is used. It is because there is a problem that the impact strength is sharply lowered.
또한, 본 발명에서 폴리프로필렌 수지로서 사용되는 에틸렌-프로필렌 랜덤 공중합체의 에틸렌 함량은 0.5~10중량%인 것이 바람직한데, 에틸렌 함량이 0.5중량% 미만이면 공중합체의 결정화도가 필요 이상으로 높아져 생성된 조성물의 유연성 및 연신력을 저하시키게 되며, 10중량%를 초과하면 결정화도가 급격히 저하되어 내열성이 떨어져 장기간 시트로의 사용에 제약을 받을 수 있기 때문이다.In addition, the ethylene content of the ethylene-propylene random copolymer used as the polypropylene resin in the present invention is preferably 0.5 to 10% by weight. If the ethylene content is less than 0.5% by weight, the degree of crystallinity of the copolymer is higher than necessary to produce This is because the flexibility and elongation of the composition is lowered, and when it exceeds 10% by weight, the crystallinity is sharply lowered and heat resistance is lowered, which may limit the use of the sheet for a long time.
본 발명에서 폴리프로필렌 수지로서 사용되는 상기 에틸렌-프로필렌 랜덤-블록 공중합체는 두가지 중합이 반응기에서 순차적으로 진행되므로써 제조될 수 있다. 먼저, 중합반응장치에 에틸렌과 프로필렌을 동시에 투입하여 에틸렌과 프로필렌을 랜덤 공중합시켜 결정성 에틸렌-프로필렌 랜덤 공중합부분을 얻은 후, 이어지는 일련의 반응에서 탄성 에틸렌-프로필렌 블록 공중합부분을 더 형성시키므로써, 최종적으로 에틸렌-프로필렌 랜덤-블록 공중합체가 만들어진다.The ethylene-propylene random-block copolymer used as the polypropylene resin in the present invention can be prepared by two polymerizations proceeding sequentially in a reactor. First, ethylene and propylene are simultaneously introduced into the polymerization reactor to random copolymerize ethylene and propylene to obtain a crystalline ethylene-propylene random copolymerization portion, and then further form an elastic ethylene-propylene block copolymerization portion in a subsequent series of reactions. Finally, an ethylene-propylene random-block copolymer is made.
상기 에틸렌-프로필렌 랜덤-블록 공중합체는 상기 결정성 에틸렌-프로필렌 랜덤 공중합부분 65~95중량%와 상기 탄성 에틸렌-프로필렌 블록 공중합부분 5~35중량%를 함유하는 것이 바람직하다. 탄성 에틸렌-프로필렌 블록 공중합부분이 5중량% 미만이면 내충격 특성에 문제가 있고, 35중량% 초과이면 딥드로잉시 백화 발생의 문제가 있기 때문이다. The ethylene-propylene random-block copolymer preferably contains 65 to 95% by weight of the crystalline ethylene-propylene random copolymerization part and 5 to 35% by weight of the elastic ethylene-propylene block copolymerization part. If the elastic ethylene-propylene block copolymerization part is less than 5% by weight, there is a problem in impact resistance, and if it exceeds 35% by weight, there is a problem of whitening during deep drawing.
상기 에틸렌-프로필렌 랜덤-블록 공중합체에 있어서, 상기 결정성 에틸렌-프로필렌 랜덤 공중합부분중의 에틸렌 함량은 0.5~10중량%인 것이 바람직하다. 에틸렌 함량이 0.5중량% 미만이면 공중합체의 결정화도가 필요 이상으로 높아져 생성된 조성물의 유연성 및 연신력을 저하시키게 되며, 10중량%를 초과하면 결정화도가 급격히 저하되어 내열성이 떨어져 장기간 시트로의 사용에 제약을 받을 수 있기 때문이다.In the ethylene-propylene random-block copolymer, the ethylene content in the crystalline ethylene-propylene random copolymerization portion is preferably 0.5 to 10% by weight. If the ethylene content is less than 0.5% by weight, the degree of crystallinity of the copolymer is higher than necessary to reduce the flexibility and elongation of the resulting composition. If the content is more than 10% by weight, the crystallinity is rapidly lowered and the heat resistance is lowered. This can be restricted.
또한, 상기 에틸렌-프로필렌 랜덤-블록 공중합체에 있어서, 상기 탄성 에틸렌-프로필렌 블록 공중합부분중의 에틸렌 함량은 20~70중량%인 것이 바람직하다. 에틸렌 함량이 20중량% 미만이거나 70중량% 초과인 경우에는, 공중합체의 탄성이 감소하여 내충격성이 저하되기 때문이다.Further, in the ethylene-propylene random-block copolymer, the ethylene content in the elastic ethylene-propylene block copolymerization portion is preferably 20 to 70% by weight. This is because when the ethylene content is less than 20% by weight or more than 70% by weight, the elasticity of the copolymer decreases and impact resistance decreases.
또한, 본 발명에서 사용되는 상기 에틸렌-프로필렌 랜덤-블록 공중합체의 n-데칸 용매에 대한 가용 부분의 절대 점도는 0.5~4.0dl/g인 것이 바람직하다. 절대점도가 0.5dl/g 미만인 경우에는 조성물의 가공시 성형직후에는 분산성이 양호하나, 에틸렌-프로필렌 랜덤 공중합부분의 결정화도가 진행됨에 따라 제품 표면으로 빠져 나오는 현상이 발생하여 제품의 외관을 크게 해치게 되고, 절대 점도가 4.0dl/g을 초과하는 경우에는 조성물의 성형시 에틸렌-프로필렌 블록 공중합부분의 분자량이 증가하여 연신율이 감소하기 때문이다.Moreover, it is preferable that the absolute viscosity of the soluble part with respect to the n-decane solvent of the said ethylene propylene random-block copolymer used by this invention is 0.5-4.0 dl / g. If the absolute viscosity is less than 0.5 dl / g, the dispersibility is good immediately after molding during the processing of the composition, but as the crystallinity of the ethylene-propylene random copolymerization progresses, a phenomenon occurs to the surface of the product, which greatly damages the appearance of the product. When the absolute viscosity exceeds 4.0 dl / g, the molecular weight of the ethylene-propylene block copolymerization portion is increased during molding of the composition, thereby reducing the elongation.
