Description

technical field [0001] The invention relates to an environment-friendly flame-retardant PE material, a preparation method and application thereof, and belongs to the technical field of polymer materials. Background technique [0002] Polyethylene material is a common general-purpose thermoplastic, widely used in packaging materials, daily necessities, pipes and other fields, but polyethylene is a flammable material, its oxygen index is only 17.3, and it produces molten droplets when burning, which is not easy to extinguish. Its scope of use, especially electronic packaging materials, so it should be treated with flame retardant modification. [0003] At present, the flame retardant modification of polyethylene is mainly based on halogen-containing flame retardants, which have many disadvantages such as high toxicity and high smoke generation. Contents of the invention [0004] The purpose of the present invention is to provide a nano-kaolin composite nitrogen-phosphorus c...
