Abstract

The invention relates to cycloaliphatic epoxy resin and a preparation method thereof. The method comprises the following steps of: taking dicycloacrylate as a raw material, hydrogen peroxide solutionas an oxidizing agent and halocarbon or halogenated hydrocarbon as a catalyst and synthesizing the cycloaliphatic epoxy resin under the action of a heteropolyacid catalyst, wherein the main reaction product of the cycloaliphatic epoxy resin, namely epoxy cyclohexane-4-carboxylic epoxycyclohexane-4-methylene ester accounts for over 90 weight percent and the epoxy equivalent weight is between 120 and 140. Each quality index of the cycloaliphatic epoxy resin of the invention is the same as that of the cycloaliphatic epoxy resin prepared by using a peroxyacetic acid as the oxidizing agent. The cycloaliphatic epoxy resin of the invention can be used as an automobile paint, a metal surface paint and an insulative substrate resin in the field of electronic and electric appliances.

Description

technical field

[0001] The invention relates to a cycloaliphatic epoxy resin and a preparation method thereof, belonging to the technical field of epoxy resins. Background technique

[0002] Cycloaliphatic epoxy resin (the main component is epoxycyclohexane-4-carboxylic acid epoxycyclohexane-4-methylene ester) has good insulation, heat resistance, chemical corrosion resistance, mechanical performance, low volume shrinkage after curing and good adhesion to a variety of substrates. Therefore, as a resin with excellent comprehensive performance, it is widely used in the fields of automotive paint, metal surface paint, and electronic appliances. However, the production of this cycloaliphatic epoxy resin uses peroxyacetic acid as an oxidizing agent, and there is a greater danger in the production process; The study of -methylene esters has always been the focus of research and attention of experts in this field.

[0003] From the current worldwide research situation, the main ...
