Disclosed in the present invention are a novel triazine compound, a preparation method therefor, and a composition comprising said compound. The triazine compound can be used in a variety of organic materials to prevent UV damage, such as polyols, plastics, adhesives, coatings, sunscreen, textiles, and pharmaceutical applications. The triazine compound of the present invention comprises propionate or a propionamide functional group, and/or polyoxyalkylene, and/or polyester, and therefore has low extraction performance, low mobility, and high compatibility. The compound of the present invention may also comprise a reactive functional group such as OH, SH, NH, and NH2, so that the low extraction performance, low mobility, and high compatibility effects are more pronounced.
