Abstract
The present disclosure relates to the technical field of the epoxy resin, specifically, relates to a preparation method a low-chlorine epoxy resin and use thereof, which can solve the problem of a high total chlorine content in the epoxy resin to a certain extent. The preparation method of a low-chloride epoxy resin comprises: loading a metal oxide as a stationary phase on a grid inside a reaction kettle; the reaction kettle being externally connected to an alternating-current power supply, and under a first pre-set condition, diluted epoxy resin containing a chlorine impurity, as a mobile phase, flowing through the grid loaded with the metal oxide; the epoxy resin containing a chlorine impurity contacting and reacting with the metal oxide to obtain a purified epoxy resin.

A preparation method of a low-chlorine epoxy resin, comprising:
- loading a metal oxide on a grid inside a reaction kettle, the metal oxide representing a stationary phase;
- supplying power to the reaction kettle from an externally connected alternating-current power supply,
- providing an epoxy resin that has been diluted with a solvent, the epoxy resin containing a chlorine impurity, and
- flowing the diluted epoxy resin, as a mobile phase, through the stationary phase under a first pre-set condition;
- wherein the epoxy resin containing a chlorine impurity contacts and reacts with the metal oxide to provide a purified epoxy resin.
