Title (EN) PHOTOPOLYMERIZED RESIN COMPOSITION AND OPTICAL FIBER MANUFACTURED WITH SAME
(FR) COMPOSITION DE RÉSINE DE PHOTOPOLYMÉRISÉE ET FIBRE OPTIQUE FABRIQUÉE AU MOYEN DE CELLE-CI
(KO) 광중합형 수지 조성물 및 이를 사용하여 제조되는 광섬유
Abstract: front page image
(EN)The present invention relates to a photopolymerized resin composition wherein a low viscosity multifunctional urethane acrylate oligomer is contained to enable a film to have a low shrinkage and low expansion ratio after ultraviolet hardening and high temperature immersion into water, and minimize the ratio of the tensile strength and adhesion of the coating and strip force of optical fibers measured before and after an immersion into water. The present invention also relates to an optical fiber using the composition. The photopolymerized resin composition according to the present invention consists of: 40 to 80 wt % of a photopolymerized urethane (meth)acrylate oligomer; 10 to 40 wt % of a low viscosity multifunctional urethane acrylate oligomer; and 1 to 10 wt % of a photoinitiator.
(FR)La présente invention concerne une composition de résine photopolymérisée contenant un oligomère uréthane acrylate multifonctionnel de faible viscosité de façon à conférer à un film un rapport de rétrécissement et d'extension faible après le durcissement aux ultraviolets et l'immersion à température élevée dans l'eau, et à minimiser le rapport de la résistance à la traction et l'adhésion du revêtement et la résistance de la bande de fibres optiques mesurés avant et après l'immersion dans l'eau. La présente invention concerne également une fibre optique utilisant la composition. La composition de résine photopolymérisée de cette invention comprend : de 40 à 80 % en poids d'un oligomère uréthane-méthacrylate photopolymérisée; de 10 à 40 % en poids d'un oligomère uréthane acrylate multifonctionnel de faible viscosité et de 1 à 10 % en poids d'un photo-initiateur.
(KO)본 발명은 저점도 다관능 우레탄아크릴레이트 올리고머를 포함하여 자외선 경화 후 필름이 고온 침수 후에 수축율와 팽창율이 낮아 침수 전과 후의 코팅제의 인장강도, 접착력 및 광섬유의 strip force 비율이 최소화된 광중합형 수지 조성물 및 이를 이용한 광섬유에 관한 것으로서, 본 발명에 따른 광중합형 수지 조성물은, 광중합형 우레탄(메타)아크릴레이트 올리고머 40 ~ 80 중량%; 저점도 다관능 우레탄아크릴레이트 올리고머 10 ~ 40 중량%; 광개시제 1 ~ 10 중량%를 포함한다.
