Hardener for an epoxy resin compound, method for curing an epoxy resin compound, epoxy resin compound, and utilizations thereof

摘要

A hardener for an epoxy resin includes an accelerator having a tetraalkylphosphonium salt. The tetraalkylphosphonium salt has the following formula: ;R′, R″, R′″, R″″ are individually-selected alkyls ranging from C₂ to C₂₀, ;X^− is an anion such as Hal^−, ClO₄^−, RCO₂(Ac^−), MX′₆^−; where M is P, As, Sb; and X^− is Hal^−. ;The hardener, an application thereof in the fabrication of an epoxy resin, the epoxy resin itself, and a method for curing an epoxy resin compound, create a material system that is suitable for the field of optoelectronics.
