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.

Abstract: The present disclosure directs to the technical field of epoxy resins, and particularly relates to an antichlor and a preparation method as well as an application thereof, for solving problems in existing chlorine removal methods that separation efficiency of an epoxy resin containing hydrolyzable chlorine is low, lots of energy needs to be consumed in the separation process, molecular distillation equipment is expensive and requirements on vacuum degree and material tightness are high. The antichlor is a polymer containing keto-carbonyl groups. The preparation method includes: adding a mixed solution of styrene and ketene into a reactor containing an organic solvent; adding an initiator, a coupling agent and an anti-gelling agent into the reactor under an atmosphere of shielding gas; controlling the styrene and ketene to perform a polymerization reaction under first preset reaction conditions; and removing the organic solvent after completion of the polymerization reaction, thereby obtaining the antichlor.
