Core-shell type nano composite insulating material and preparation method thereof

Abstract

The invention provides a core-shell type nano composite insulating material and a preparation method thereof, belongs to the technical field of high-voltage cable insulating materials, and provides the core-shell type nano composite insulating material and the preparation method thereof, and belongs to the technical field of high-voltage cable insulating materials. The invention relates to a zinc oxide nano-composite material, which comprises the following components by weight: a base material, 2-4 wt% of a core-shell nano-modifier, 1-2 wt% of a cross-linking agent and 0.2-1 part of an oxidizing agent, and the core-shell nano-modifier comprises 100 parts of zinc oxide nano-particles, 15-25 parts of sodium silicate, diluted hydrochloric acid, deionized water and a composite surface modification raw material. And collaborative optimization of the dispersion stability and the trap effect is difficult to realize at the same time.
