Description

N-取代的三嗪受阻胺光稳定剂及其制备方法和应用 技术领域
本发明涉及高分子材料领域，特别涉及一种聚合型受阻胺光稳定剂、制备方法及其应用。
背景技术
随着人类生活质量以及生产技术水平的不断提高，高分子材料已经广泛应用到人类社会生活的各个领域。但高分子材料在加工、贮存和使用的过程中，普遍存在其物理性质、化学性质和力学性能会逐渐变差的现象。例如塑料的发黄、脆化与开裂；橡胶的发粘、硬化、龟裂及绝缘性能下降。纤维制品的变色、褪色、强度降低、断裂等现象。这些现象统称为高分子材料的老化或者降解。造成高分子材料老化的因素很多，其中以氧、光和热的影响最为显著。所以为了防止或延缓其老化，延长其使用寿命，人们通常将一些具有特定功能的化学助剂添加到高分子材料中。其中，光稳定剂就是一类能够干预高分子材料光诱导降解物理化学过程的化合物，是最常用也是最重要的高分子材料添加剂之一。
目前光稳定剂的品种主要包括紫外线吸收剂、猝灭剂、自由基捕获剂和光屏蔽剂。自由基捕获剂能捕获高分子中所生成的活性自由基，从而抑制光氧化过程，达到光稳定目的。自由基捕获剂主要类型是受阻胺光稳定剂，受阻胺光稳定剂因其优异的光稳定效果受到广泛的关注，是近二、三十年来国内外研究最活跃的一类光稳定剂。虽然这类光稳定剂开发的比较晚，但是发展迅速。目前国外应用的光稳定剂中受阻胺类光稳定剂已占60％左右。在国内，受阻胺类光稳定剂所占比重更高，约80％左右。
受阻胺光稳定剂有：哌啶衍生物、咪唑酮衍生物和氮杂环烷酮衍生物等系列。哌啶衍生物研究得比较多，发展也最快，已有不少品种供应市场。专利文献CN105636954A公开了一种三嗪、哌啶和吡咯烷基受阻胺光稳定剂，将其添加到含有对由光、热或氧化所致的降解敏感的有机物质中可起到稳定作用，但是合成该光稳定剂的单体吡咯烷易燃、有毒，其蒸汽与空气可形成爆炸性混合物，所以制备三嗪、哌啶和吡咯烷基受阻胺光稳定剂的过程中存在较大的危险性。
在本发明中，发明人提供一种化合物，可作为含有对光、热或氧化所致的降解敏感的有机物质的稳定剂和有机物质阻燃剂，并且制备简单，操作安全。
发明内容
本发明的目的是提供一种N-取代的三嗪受阻胺光稳定剂；本发明另一个目的是提供一种N-取代的三嗪受阻胺光稳定剂的用途。本发明的另一个目的是提供一种包含N-取代的三嗪受阻胺光稳定剂的组合物；本发明还一个目的是提供一种上述组合物的用途。
