The invention discloses a high-dispersity antimony oxide flame-retardant master batch based on nano modification and a preparation method thereof, and belongs to the technical field of flame-retardant modification of high polymer materials. The flame-retardant master batch consists of the following components in percentage by weight: 30-50% of nano antimony oxide, 3-8% of a dispersion modifier, 40-65% of carrier resin and 1-5% of a dispersing aid. The preparation method comprises the steps of nano antimony oxide pretreatment, mixing, melt extrusion, granulation and the like. Nano antimony oxide is subjected to surface modification through the dispersion modifier, and the synergistic effect of the auxiliary dispersant and the carrier resin is combined, so that the surface energy of the nano antimony oxide is effectively reduced, the problem that the nano antimony oxide is easy to agglomerate in a polymer matrix is solved, and high dispersity is realized; meanwhile, the flame-retardant synergistic efficiency is remarkably improved, the stability of the flame-retardant property of the material is ensured, and the mechanical property and the processing fluidity of a high polymer material are not damaged.

This invention discloses an anti-aging power metering box cabinet material, relating to the field of organic materials technology. The anti-aging power metering box cabinet material comprises the following raw materials by weight percentage: 25%-35% unsaturated polyester resin, 11%-15% low-shrinkage agent, 0.5%-2% initiator, 2.5-8% additives, 35%-50% organic composite filler, and 15%-25% modified chopped glass fiber. This application adds the prepared modified chopped glass fiber to the unsaturated polyester resin, along with the remaining additives required for preparing the electrical cabinet material, to obtain the cabinet material for use in power metering boxes. The power metering box cabinet material prepared in this application has advantages such as excellent mechanical properties, stable environmental aging resistance, low dielectric loss, and low dielectric constant.

The invention discloses a silicone rubber / EVA (Ethylene-Vinyl Acetate) / modified bamboo powder ternary synergistic composite foam material and a preparation method thereof. The composite foaming material is prepared from the following components in parts by mass: 80 to 90 parts of silicone rubber base rubber, 5 to 15 parts of modified bamboo powder, 10 to 20 parts of EVA (Ethylene Vinyl Acetate) resin, 3 to 7 parts of foaming agent, 0.5 to 1.5 parts of vulcanizing agent, 1 to 4 parts of antioxidant and 0.2 to 2 parts of release agent. According to the invention, the interfacial compatibility with silicone rubber and EVA (ethylene-vinyl acetate copolymer) is improved through bamboo powder modification, and the comprehensive performance of the composite foam material is optimized.
