Resin composition for electric insulation and its hardened products, as well as coils, stators, rotary machines, and high voltage equipment using the products |
摘要 |
Disclosed is a resin composition for electric insulation which contains an epoxy resin; a hardening agent; and fine particles, in which the fine particles form a plurality of threadlike agglomerates and the agglomerates have a dendritic structure when the epoxy resin, the hardening agent, and the fine particles are mixed and hardened, a base material of the fine particle is formed of silicon dioxide, aluminum oxide, titanium oxide, or boron nitride, and hydrophilic groups and hydrophobic groups are present together on a surface of the base material. Thus improvement of the electric characteristics and the mechanical characteristics of the insulation material and suppression of viscosity of the resin composition are made compatible. |
