Abstract

본 발명은 메틸렌 디페닐 디이소시아네이트 또는 톨루엔 디이소시아네이트와 같은 방향족 이소시아네이트를 제조 생산하여 장기간 보관중이거나 사용중에 변색을 일으키는 것을 방지하고 장기간 보관이 가능할 수 있도록 한 방향족 이소시아네이트 화합물의 변색 방지 조성물에 관한 것이다.The present invention relates to an anti-discoloration composition of an aromatic isocyanate compound which is manufactured and produced in an aromatic isocyanate such as methylene diphenyl diisocyanate or toluene diisocyanate to prevent discoloration during long-term storage or use and to enable long-term storage.

구체적으로 말하면, 일반식(I)의 화합물과 인산계 산화방지제 및 트리아졸계 광안정제를 병용하거나 또는 일반식(I)의 화합물과 페놀계 산화방지제 및 트리아졸계 광안정제를 병용하거나 또는 일반식(I)의 화합물과 인산계 및 페놀계 산화 안정제를 병용하게 되면 방향족 이소시아네이트 화합물의 변색방지에 탁월한 효과가 있음을 알 수 있다.Specifically, the compound of the general formula (I) and the phosphoric acid antioxidant and the triazole light stabilizer are used in combination, or the compound of the general formula (I) and the phenolic antioxidant and the triazole light stabilizer are used in combination or the general formula (I When the compound of) and the phosphoric acid-based and phenol-based oxidative stabilizer are used in combination, it can be seen that there is an excellent effect in preventing discoloration of the aromatic isocyanate compound.
