The application belongs to the field of high polymer materials, and particularly relates to a modified polypropylene foaming material and a preparation method thereof. The modified polypropylene foaming material is prepared from a blank through mold foaming, and the preparation raw materials of the blank include, in parts by weight, 50-90 parts of homopolymer polypropylene, 10-40 parts of polystyrene, 1-10 parts of fluorine-containing functional monomer, 0.01-0.5 parts of initiator, 0.01-1 parts of catalyst, 0.1-0.5 parts of nucleating agent, 1-10 parts of decabromodiphenyl ethane, 0.2-5 parts of antimony trioxide and 0.05-5 parts of anti-dripping agent. The homopolymer polypropylene is modified by using multiple components in cooperation, so that the comprehensive performance of the material is significantly improved. The material has the advantages of strong stability, high Shore C hardness, large compressive strength, low dielectric constant, excellent anti-aging performance, good flame-retardant effect and wide application prospect in the field of new energy vehicles.

This invention provides an irradiated crosslinked, hydrolysis-resistant, low-halogen flame-retardant insulating material for energy storage cables and its preparation method, comprising the following raw material components in parts by weight: 43-51 parts of resin composition, 43-49 parts of flame-retardant composition, and 6.7-8 parts of auxiliary composition. The resin composition comprises the following components in parts by weight: 18-20 parts of ethylene-vinyl acetate copolymer; 10-12 parts of metallocene linear polyethylene; 7-9 parts of polyethylene elastomer; and 8-10 parts of POE graft compatibilizer. The flame-retardant composition comprises the following components in parts by weight: 12-14 parts of magnesium hydroxide; 21-23 parts of decabromodiphenyl ethane; and 10-12 parts of antimony trioxide. This results in a product exhibiting excellent mechanical properties, flame-retardant properties, hydrolysis resistance, long-term aging performance, and processing performance, with overall performance significantly superior to existing ordinary polyolefin insulating materials.

This invention relates to the field of cable technology and proposes a long-life overhead insulated cable. This long-life overhead insulated cable includes a conductor and an insulation layer. The insulation layer comprises the following raw materials in parts by weight: 80-100 parts high-density polyethylene, 10-20 parts polyolefin elastomer, 5-10 parts ethylene-vinyl acetate copolymer, 4-8 parts composite powder, 12-18 parts decabromodiphenyl ethane, 4-6 parts antimony trioxide, 0.5-1 part antioxidant, and 2.5-5 parts lubricant; wherein the composite powder is a core-shell structure inorganic particle with an organic ultraviolet absorber grafted onto the surface of ZnO@CeO2 core-shell particles. The long-life overhead insulated cable of this invention achieves the synergistic effect of inorganic ultraviolet shielding and organic ultraviolet absorption, significantly improving the cable insulation layer's resistance to ultraviolet aging, mechanical toughness, and weather resistance, effectively extending the service life of the overhead cable in complex outdoor environments.
