Abstract

The invention discloses a rare-earth chloride and intumescent flame retardant synergic flame retardance polypropylene composite and a preparation method thereof. The composite is prepared from rare-earth chloride, an intumescent flame retardant and polypropylene. Rare-earth chloride is introduced into an intumescent flame retardant flame-resistant polypropylene material, rare-earth chloride and the intumescent flame retardant can achieve a synergic flame retardance effect, and the physical and mechanical performance of the intumescent flame retardant flame-resistant polypropylene material is effectively improved while the use amount of the intumescent flame retardant is reduced.

Description

technical field [0001] The invention relates to the technical fields of organic synthesis, blending of polymer composite materials, and testing of flame-retardant properties of materials, in particular to a flame-retardant polypropylene composite material synergized by rare earth chlorides and intumescent flame retardants and a preparation method thereof. Background technique [0002] Polypropylene (PP) is one of the most widely used general-purpose plastics, and it is widely used in industries such as packaging, textiles, building materials, automobiles, electronic appliances, and office supplies. But polypropylene is flammable, its oxygen index value is low, only 17-18%, and it will produce a lot of molten droplets when burning, which is easy to cause fire and cause the fire to spread rapidly. [0003] At present, in the field of polypropylene flame retardant, bromine-based flame retardant dominates the market. However, brominated flame-retardant polypropylene not only pr...
