| titleOfInvention | A kind of nano-silica modified low-density polyethylene composite material and preparation method |
| abstract | The invention relates to the technical field of insulating materials, and discloses a nano-silica modified low-density polyethylene composite material, a low-density polyethylene grafted with maleic anhydride, which reduces the heat resistance caused by the low melting point of the low-density polyethylene. As a nanomaterial with high dielectric constant and excellent thermal stability, nano-silica has a large specific surface area, can provide higher active sites, and can be modified by amination. After that, active groups are obtained on the surface of inorganic nanomaterials, and under the nucleophilic action of amino groups, ring-opening reaction occurs with the acid anhydride groups of maleic anhydride grafted low-density polyethylene, which improves the interfacial bonding force between the two. The dispersibility of nano-silica in the low-density polyethylene matrix is significantly improved, the agglomeration is effectively reduced, and the nano-silica modified low-density polyethylene composite material exhibits good thermal aging resistance and tensile properties. |
