Summary:The present invention relates to a xylene diisocyanate composition and a method for producing isocyanurate using same, wherein the content of chloromethylbenzyl isocyanate in the xylene diisocyanate composition is optimized, whereby it is possible to produce, with high reaction efficiency, isocyanurate having excellent film drying properties, coating heat resistance, weather resistance, and compatibility with a solvent, due to optimized reactivity to prevent a gelation reaction, and also reuse same due to excellent storage stability of the xylene diisocyanate composition recovered after reaction. La présente invention concerne une composition de diisocyanate de xylène et un procédé de production d'isocyanurate l'utilisant, la teneur en isocyanate de chlorométhylbenzyle dans la composition de diisocyanate de xylène étant optimisée, ce par quoi il est possible de produire, avec une efficacité de réaction élevée, un isocyanurate ayant d'excellentes propriétés de séchage de film, de résistance à la chaleur de revêtement, de résistance aux intempéries et de compatibilité avec un solvant, en raison d'une réactivité optimisée pour empêcher une réaction de gélification, et également de réutilisation en raison d'une excellente stabilité au stockage de la composition de diisocyanate de xylène récupérée après réaction. 본 발명은 자일렌 디이소시아네이트 조성물 중 클로로메틸벤질 이소시아네이트의 함량을 최적화함으로써, 겔화 반응이 나타나지 않도록 최적화된 반응성으로 막 건조성이 우수하고 코팅 내열성이 좋고 내후성이 뛰어나며 용매와의 융합성이 좋은 이소시아누레이트를 높은 반응 효율로 제조할 수 있을 뿐만 아니라, 반응후 회수된 자일렌 디이소시아네이트 조성물의 우수한 보관 안정성으로 재사용 가능한, 자일렌 디이소시아네이트 조성물 및 이를 이용하여 이소시아누레이트의 제조 방법에 관한 것이다.
