이하, 본 발명을 바람직한 실시예와 첨부된 도면과 사진을 참조하여 상세하게 설명하면 다음과 같다.Hereinafter, described in detail with reference to the preferred embodiment and the accompanying drawings and photos as follows.

도 1에서 본 발명은 클로로프린 100중량부당 CNT 1중량부, 톨루엔 40중량부, 계면활성제 2중량부를 섞어서 준비하는 준비단계(100)와;상기 준비단계의 재료를 세라믹볼이 포함된 교반기에 넣고 8~24시간 동안 고속 교반하는 분산단계(200)와; 상기 분산단계(200) 후의 재료를 드라이챔버에서 8~12시간 방치하여 톨루엔을 증발시키는 톨루엔증발단계(300)와; 상기 톨루엔증발단계(300) 후의 재료를 2본롤에서 클로로프린과 함께 균일하게 교반하는 합성단계(400)와; 상기 합성단계 후에 절단 하고, 숙성시키는 숙성단계(500)와; 상기 숙성단계(500) 후의 재료를 2본롤에서 다시 분산시키는 제2분산단계와(600); 상기 제2분산단계(600) 후의 재료를 발포하여 고무조성물을 완성하는 완성단계(700)로 구성된다. In the present invention 1 is prepared by mixing 100 parts by weight of CNT, 100 parts by weight of toluene 40 parts by weight of surfactant, and 2 parts by weight of surfactant; and preparing the material of the preparation step in a stirrer containing a ceramic ball A dispersion step 200 of stirring at high speed for 8 to 24 hours; A toluene evaporation step 300 for evaporating toluene by leaving the material after the dispersing step 200 in a dry chamber for 8 to 12 hours; A synthesis step 400 of uniformly stirring the material after the toluene evaporation step 300 together with chloroprene in two rolls; After the synthesis step is cut and aged to mature (500); A second dispersion step 600 of dispersing the material after the aging step 500 again in two rolls; It is composed of a completion step 700 of foaming the material after the second dispersion step 600 to complete the rubber composition.

상기 준비단계(100)에서는 클로로프린 100중량부당 CNT 1중량부, 톨루엔 40중량부와 계면활성제 2중량부를 섞는데, 계면활성제는 양이온계면활성제와 음이온계면활성제가 공존하는 것을 사용한다. In the preparation step 100, 1 part by weight of CNT, 40 parts by weight of toluene and 2 parts by weight of surfactant are mixed per 100 parts by weight of chloroprine, and a surfactant is used in which a cationic surfactant and an anionic surfactant coexist.

상기 계면활성제는 일반적으로 주방용세제로 사용되는 것을 사용한다. The surfactant is generally used as a dishwashing detergent.

상기 분산단계(200)의 교반기는 내부에 초고속(3000~4000rpm)으로 회전하는 원반형교반날개가 형성되고, 내부에 상기 준비단계(100)의 재료를 넣고 지름 1mm의 다수개의 세라믹볼을 삽입한다. The stirrer of the dispersing step 200 is a disk-shaped stirring blade is rotated at an ultra-high speed (3000 ~ 4000rpm) is formed therein, the material of the preparation step 100 is inserted therein and insert a plurality of ceramic balls of diameter 1mm.

상기 분산단계(200)에서는 원반형교반날개를 3000~4000rpm으로 회전시키면서 8~24시간 분사한다.In the dispersing step 200, the disk-shaped stirring blade is sprayed for 8 to 24 hours while rotating at 3000 ~ 4000rpm.

상기 분산단계(200)를 거치게 되면 계면활성제가 CNT의 표면을 코팅하여 서로 엉기지 못하도록 하여 분사된다.When the dispersion step 200 is passed, the surfactant is sprayed by coating the surface of the CNTs to prevent them from being entangled with each other.

상기 톨루엔증발단계(300)는 65~85℃로 유지되는 드라이챔버 내부에 방치하여 톨루엔이 40중량부에서 10~15중량부로 될 때까지 증발시키는 단계이다. The toluene evaporation step 300 is a step of evaporating toluene from 10 parts by weight to 10 parts by weight by leaving it in the dry chamber maintained at 65 ~ 85 ℃.

상기 합성단계(400)는 톨루엔 10~15중량부 남아있는 재료에 톨루엔 40중량부당 클로로프린 100중량부를 넣은 후 2본롤(기계적분산장치)에서 교반하는 단계이다. The synthesis step 400 is a step of stirring in two rolls (mechanical dispersing apparatus) after putting 100 parts by weight of chloroprine per 40 parts by weight of toluene to 10-15 parts by weight of toluene remaining material.

상기 숙성단계(500)는 상온에서 이루어지고, 24~48시간 가량 숙성시킨다. The aging step 500 is made at room temperature, and aged for 24 to 48 hours.

상기 완성단계(700)는 종래의 스폰지 제작하는 방법과 동일하게 발포하는 것으로, 톨루엔이 완전히 증발된 상태에서 작업을 하게 된다. The completion step 700 is to foam in the same manner as the conventional sponge manufacturing method, the toluene is completely evaporated to work.

상기와 같이 톨루엔에 의해서 CNT가 클로로프린의 내부에 분산되어 있기 때문에 CNT로 인한 인장강도, 인열강도, 압축영구줄음율등의 기계적 강도의 증가가 고무조성물의 전체적으로 고르게 분포된다. As described above, since CNTs are dispersed in the chloroprin by toluene, an increase in mechanical strength such as tensile strength, tear strength, and compressive permanent shrinkage due to CNT is uniformly distributed throughout the rubber composition.

도 2와 도 3은 바람직한 실시예로 형성된 고무조성물의 시편의 전자현미경 사진으로, 탄소나노튜브가 고무조성물의 전체에 고르게 분포된 것을 알 수 있다. 2 and 3 are electron micrographs of the specimen of the rubber composition formed in a preferred embodiment, it can be seen that the carbon nanotubes are evenly distributed throughout the rubber composition.

상기와 같이 탄소나노튜브가 분포될 수 있는 것은 톨루엔에 의해서 계면활성제가 탄소나노튜브의 표면을 고르게 코팅(coating)해주어 탄소나노튜브간의 인력을 떨어뜨리는 결과를 초래하므로 분산이 이루어지는 것이다.As the carbon nanotubes are distributed as described above, the surfactant is uniformly coated on the surface of the carbon nanotubes by toluene, resulting in a drop in the attraction between the carbon nanotubes, and thus dispersion is performed.

상기한 것과 같이 본 발명에 의한 탄소나노튜브의 분상방법 및 분산된 탄소나노튜브를 함유한 고무조성물에 의하면 다음과 같은 효과가 발생한다.As described above, according to the powder composition of the carbon nanotubes according to the present invention and the rubber composition containing the dispersed carbon nanotubes, the following effects occur.
