Description
본 발명은 스티렌-부타디엔-스티렌 블록공중합체(이하, SBS라 함) 수지 조성물에 관한 것으로서, 더욱 상세하게는 SBS를 기본수지로 하고 보강재로 유기화된 몬모릴로나이트와 카본블랙을 첨가시킴으로써 SBS 수지 조성물의 내열성 및 마모도 등의 물성을 향상시킨 열가소성 수지 조성물에 관한 것이다.The present invention relates to a styrene-butadiene-styrene block copolymer (hereinafter referred to as SBS) resin composition, and more particularly, to the heat resistance of the SBS resin composition by adding montmorillonite and carbon black organicized as a base resin with SBS as a reinforcing material. And a thermoplastic resin composition having improved physical properties such as wear.
유기화된 몬모릴로나이트를 폴리머에 분산시켜 나노복합재를 제조하는 기술은 1987년 일본 Toyota 연구진들에 의해 최초로 개발된 기술로서, 적절한 방법으로 나일론 단량체를 실리케이트층 사이에 삽입시키고 이를 층간 중합함으로써 층간 거리가 100Å 가까이 증가하도록 한 기술이다. 이와같은 기술을 통해 나일론 수지의 물성이 기존의 무기 보강재를 사용한 것 보다 훨씬 적은 양을 사용하더라도 동등한 물성을 발현 할 수 있다고 보고하였으며, 이와같은 개발 이래로 일본, 미국 등 선진국에서 활발히 그 연구가 진행 중이다(Journal of Polymer Science. Part B; Polymer Chemistry, Vol. 31, 1755-1758(1993), Journal of Polymer Science. PartB; Polymer Physics, Vol. 32, 625-630(1994)).The technique for producing nanocomposites by dispersing organic montmorillonite in polymers was first developed by Toyota researchers in Japan in 1987. The interlaminar distance is close to 100 함으로써 by inserting nylon monomers between silicate layers and polymerizing them in an appropriate manner. It is a technique to increase. Through this technology, it is reported that even if the properties of nylon resin are used in much smaller amounts than those of conventional inorganic reinforcing materials, the same properties can be expressed. Since the development, the research is being actively conducted in advanced countries such as Japan and the US (Journal of Polymer Science.Part B; Polymer Chemistry, Vol. 31, 1755-1758 (1993), Journal of Polymer Science.Part B; Polymer Physics, Vol. 32, 625-630 (1994)).
한편, 고분자 나노복합재에 사용되는 몬모릴로나이트는 높은 축비(aspect ratio: 500∼1000)를 가진 대표적인 2:1 스멕타이트(smectite)계 층상점토이다. 몬모릴로나이트의 층간거리는 1㎚ 미만 정도이나 양이온의 종류 및 수분함량에 따라 층간거리가 변하게 된다. 구체적으로는, 자연상태에서는 층 사이에 Na+나 Ca2+등이 수분과 같이 존재하며 층간거리가 대략 1㎚ 미만정도인데, 탄소원자수 6∼18의 암모니윰클로라이드와 같은 유기화제로 양이온 치환반응을 시키면 층간거리가 2∼3㎚인 유기화된 몬모릴로나이트가 생성된다.On the other hand, montmorillonite used in the polymer nanocomposite is a representative 2: 1 smectite layered clay having a high aspect ratio (500 to 1000). The interlaminar distance of montmorillonite is less than 1 nm, but the interlaminar distance varies depending on the type of cation and water content. Specifically, in the natural state, Na + or Ca 2+ is present between the layers as water and the interlayer distance is less than about 1 nm. The cation substitution reaction is carried out with an organic agent such as ammonium chloride having 6-18 carbon atoms This yields an organic montmorillonite having an interlayer distance of 2-3 nm.
이와같은 유기화된 몬모릴로나이트를 사용한 나노복합재는 삽입형과 박리형으로 나눌 수 있는데 박리형 나노복합재료(exfoliated nanocomposites)는 폴리머 매트릭스에 유기화된 몬모릴로나이트층을 완전히 분산시키는 것이고, 삽입형 나노복합재료(intercalated nanocomposites)는 유기화된 몬모릴로나이트층 사이에 고분자가 삽입되어 있는 형태이다. 이와 같은 나노복합재료는 고분자 사슬의 움직임을 제약하고 층상형의 무기물이 나노사이즈로 분산됨으로써 고분자수지의 내충격성, 인성, 투명성의 손상없이 강도와 강성도, 가스투과 억제능, 방염성, 내마모성, 고온안정성을 한층 높일 수 있다고 알려져 있다.Such nanocomposites using organic montmorillonite can be divided into insert type and exfoliation type. Exfoliated nanocomposites are those which completely disperse the organicized montmorillonite layer in the polymer matrix, and intercalated nanocomposites The polymer is inserted between the organic montmorillonite layer. Such nanocomposites restrict the movement of polymer chains and disperse the layered inorganic material in nano size, so that the strength, stiffness, gas permeability, flame resistance, abrasion resistance, and high temperature stability of the polymer resin are not impaired. It is known that it can be raised further.
한편, 스티렌계 열가소성 탄성체의 대표적인 수지인 SBS는 고무 탄성의 성질을 가지면서 사출성형 가공이 가능하고 재활용이 용이하기 때문에 그 사용 범위가 점점 증가되고 있다. 그러나 사용온도의 범위가 낮고 초기 모듈러스가 낮아 다양한용도로 적용되는데 제약을 받고 있다.On the other hand, SBS, which is a typical resin of styrene-based thermoplastic elastomer, has a rubber elastic property, and therefore, its use range is gradually increasing because injection molding processing is possible and recycling is easy. However, the range of use temperature is low and the initial modulus is low, so it is limited to being applied for various purposes.
이에, 본 발명자들은 사용온도가 낮은 SBS의 내열성과 마모성, 기계적 물성을 향상시키기 위해 연구 노력하던 중, 유기화된 몬모릴로나이트가 SBS의 스티렌 블록을 강화하여 유리전이온도를 증가시키고 카본블랙이 SBS의 부타디엔 블록을 강화하여 마모도와 기계적 물성을 향상시키며, 이 두 가지 보강재를 동시에 투입한 경우 두 보강재의 장점을 모두 살릴 수 있다는 것을 알게되어 본 발명을 완성하게 되었다.Accordingly, the present inventors are working to improve the heat resistance, wear resistance, and mechanical properties of SBS having a low use temperature, while the organic montmorillonite strengthens the styrene block of SBS to increase the glass transition temperature, and carbon black is the butadiene block of SBS. In order to improve the wear and mechanical properties by reinforcing the two reinforcement at the same time it was found that the advantages of both reinforcement can be utilized to complete the present invention.
따라서, 본 발명의 목적은 사용온도의 범위가 낮고 초기 모듈러스가 낮아 다양한 용도로의 적용에 한계가 있는 SBS의 문제점을 해결하여 내열성과 마모성, 기계적 물성을 향상킬 수 있는 스티렌-부타디엔-스티렌 블록공중합체 수지 조성물을 제공하는 데 있다.Accordingly, an object of the present invention is a styrene-butadiene-styrene block which can improve the heat resistance, wear resistance, and mechanical properties by solving the problem of SBS, which has a low range of use temperature and low initial modulus, which is limited in application to various applications. It is to provide a copolymer resin composition.
이와같은 목적을 달성하기 위한 본 발명의 스티렌-부타디엔-스티렌 블록공중합체 수지 조성물은 스티렌-부타디엔-스티렌 블록공중합체 100중량부에 대하여 보강재로 유기화된 몬모릴로나이트 3∼10중량부와 카본블랙 3∼10중량부를 첨가하여 이루어진 것임을 그 특징으로 한다.The styrene-butadiene-styrene block copolymer resin composition of the present invention for achieving the above object is 3 to 10 parts by weight of montmorillonite organicized as a reinforcing material with respect to 100 parts by weight of styrene-butadiene-styrene block copolymer and 3 to 10 carbon black. It is characterized by that it is made by adding a weight part.
이와 같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.
본 발명에서 사용한 SBS는 그 종류가 특별히 한정되지 않은 바, 본 발명의 실시예와 비교에서는 충분한 흐름성이 있어 가공하기 용이한 금호석유화학에서 생산되는 KTR-201 GRADE를 사용하였다. KTR-201은 분자량이 80,000g/mol이며 스티렌 함량이 30wt%이고 용융흐름지수는 6g/10min이다.Since the type of SBS used in the present invention is not particularly limited, KTR-201 GRADE produced by Kumho Petrochemical, which has sufficient flowability and is easy to process in comparison with the embodiment of the present invention, was used. KTR-201 has a molecular weight of 80,000g / mol, a styrene content of 30wt%, and a melt flow index of 6g / 10min.
한편, 카본블랙은 천연가스, 석유의 물질을 불완 연소 또는 열분해시켜 만든 미세 흑색물질로 천연고무, 부타디엔 고무, 스티렌-부타디엔 고무 등과 같은 가황 고무의 물성을 향상시키는 보강재로 많이 사용되고 있다.On the other hand, carbon black is a fine black material produced by incomplete combustion or pyrolysis of natural gas and petroleum materials, and is widely used as a reinforcing material for improving physical properties of vulcanized rubber such as natural rubber, butadiene rubber and styrene-butadiene rubber.
본 발명에서 사용한 카본블랙은 그 종류가 특별히 한정되지 않는 바, 본 발명의 실시예와 비교에서는 고무의 마모도를 향상시킬 수 있도록 입자의 표면적이 130mg/g 이상, 구조가 120ml/100g인 카본블랙을 사용하였다. 그 사용량은 SBS 100 중량부에 대하여 10중량부 이내, 바람직하게는 3∼10 중량부이다. 만일, 카본블랙을 SBS 100중량부에 대하여 10중량부를 초과하여 사용하면 SBS의 가공성에 영향을 미치기 때문에 그 이상은 사용하지 않았다.The carbon black used in the present invention is not particularly limited in kind, and in comparison with the embodiment of the present invention, carbon black having a surface area of 130 mg / g or more and a structure of 120 ml / 100 g is used to improve the wear of rubber. Used. The amount used is 10 parts by weight or less, preferably 3 to 10 parts by weight based on 100 parts by weight of SBS. If carbon black is used in an amount exceeding 10 parts by weight based on 100 parts by weight of SBS, the processability of the SBS is affected.
본 발명에서 카본블랙과 더불어 보강재로 첨가되는 유기화된 몬모릴로나이트는 그 종류가 특별히 한정되지 않은 바, 본 발명의 실시예와 비교에서는 미국 Southern Clay사의 Cloistite 6A를 사용하였다.In the present invention, the organic montmorillonite added as a reinforcing material together with carbon black is not particularly limited in its kind, and in comparison with the embodiment of the present invention, Cloistite 6A of Southern Clay, USA was used.
Cloisite 6A은 Na-몬모릴로나이트를 다이메틸 다이하이드로게네이티드 탈로우 암모니윰(dimethyl dihydrogenated tallow amminium)으로 유기화 처리한 것이다. Cloisite 6A는 층간거리가 34.60Å 이고 유기화제의 농도가 140meq/100g 이다.Cloisite 6A is an organic treatment of Na-montmorillonite with dimethyl dihydrogenated tallow amminium. Cloisite 6A has an interlayer distance of 34.60Å and an organic concentration of 140 meq / 100g.
유기화된 몬모릴로나이트를 제조하는 방법을 구체적으로 살펴보면, Na-몬모릴로나이트 20g을 80℃의 증류수 4ℓ에 분산시킨다. 여기에 유기화된 암모니윰클로라이드 7g을 80℃ 증류수 500㎖에 녹인 후 혼합한다. 30분간 교반 후 24시간 방치를 하면 흰색 침전물이 발생한다. 흰색 침전물을 원심분리기로 분리한 후 증류수로 2∼3회 세척하고 100℃에서 24시간 건조하면 유기화된 몬모릴로나이트를 얻을 수 있다.Looking specifically at the method for producing the organic montmorillonite, 20g Na-montmorillonite is dispersed in 4L of distilled water at 80 ℃. Here, 7 g of the organic ammonium chloride was dissolved in 500 ml of distilled water at 80 ° C. and mixed. If left for 24 hours after stirring for 30 minutes, white precipitates are formed. The white precipitate is separated by a centrifuge, washed 2-3 times with distilled water, and dried at 100 ° C. for 24 hours to obtain organic montmorillonite.
이와같은 유기화된 몬모릴로나이트의 사용량은 SBS 100 중량부에 대하여 10중량부 이내, 바람직하게는 3∼10중량부이다. 만일, 10중량부를 초과하여 사용할 경우에는 유기화된 몬모릴로나이트의 가격이 고가이므로 제조 비용이 증가하게 되며 보강효과의 증가가 미미하다.The amount of such organicized montmorillonite used is within 10 parts by weight, preferably 3 to 10 parts by weight, based on 100 parts by weight of SBS. If it is used in excess of 10 parts by weight, the price of the organic montmorillonite is expensive, the manufacturing cost increases and the increase of the reinforcing effect is minimal.
