Abstract

The invention discloses a nano-clay and nitrogen phosphorus flame retardant synergistic flame retardant polypropylene material and a preparation method thereof. The nano-clay and nitrogen phosphorus flame retardant synergistic flame retardant polypropylene material comprises the following components: by weight, 62%-71% of polypropylene, 25% - 30% of a nitrogen and phosphorus flame retardant, 1%-3% of nano-clay and 3%-5% of a compatibilizer. The nano-clay and nitrogen phosphorus flame retardant synergistic flame retardant polypropylene material does not contain lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and poly brominated diphenyl ethers and other harmful substances, is low in heat producing quantity and producing smoke quantity in the process of burning, is less in damages to the environment and the human body, the nano-clay is dispersed evenly in the material, and while improvement of flame retardant properties, physical and mechanical properties and processability of the material can be maximumly maintained.

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 material synergistic with a nitrogen-phosphorus flame retardant and a preparation method thereof. technical background [0002] Polypropylene (PP) is one of the most widely used general-purpose plastics, and it is widely used in packaging, textiles, building materials, automobiles, electronic appliances, office supplies and other industries. However, polypropylene is flammable, with a low oxygen index value of only 17-18%, and a large number of molten droplets will be generated when burning, which is easy to cause fire and cause the fire to spread rapidly. [0003] At present, the flame retardant field of polypropylene mainly adopts traditional flame retardants such as halogen series, phosphorus series and inorganic hydroxides. Among them, h...
