Three-layer coated red phosphorus as well as preparation method and application thereof

The invention discloses three-layer coated red phosphorus as well as a preparation method and application thereof, and relates to the technical field of flame retardants. According to the invention, firstly, cucurbituril and derivatives thereof are adopted to coat red phosphorus, then a zinc-based metal organic framework material is adopted to coat the red phosphorus for the second time, and finally melamine and cyanuric acid are adopted to coat the red phosphorus for the third time, so that a three-layer coated red phosphorus product is obtained. The three-layer coated red phosphorus provided by the invention has high flame retardant property, and overcomes the odor problem of a phosphorus-containing flame retardant at the same time. 本发明公开了一种三层包覆红磷及其制备方法和应用，涉及阻燃剂技术领域。本发明是先采用葫芦脲及其衍生物对红磷进行包覆，然后再采用锌基金属有机骨架材料对其进行二次包覆，最后采用三聚氰胺、氰尿酸进行三次包覆，从而获得三层包覆红磷产品。本发明的三层包覆红磷具有较高的阻燃性能，同时克服了含磷阻燃剂的气味问题。
