Abstract

The invention discloses an epoxy resin curing agent and a preparation method thereof. The epoxy resin curing agent comprises the following components in percentage by mass: 42-48% of benzyl alcohol, 25-35% of isophoronediamine, 18-20% of EP-16 epoxy resin and 5-7% of triethanolamine. The concrete preparation method comprises the following steps of adding benzyl alcohol and isophoronediamine into a reaction kettle, and stirring; after uniformly stirring, adding the EP-16 epoxy resin into the reaction kettle, and then, stirring; after uniformly stirring, adding triethanolamine, heating the reaction kettle to 70 DEG C, and reacting for 1 hour; and after reacting, cooling to 25 DEG C, and sub-packaging. The epoxy resin curing agent has the advantages of good quality, low cost and the like.

Description

technical field [0001] The invention relates to a curing agent and a preparation method thereof, in particular to an epoxy resin curing agent and a preparation method thereof. Background technique [0002] Epoxy resin is an important class of thermosetting plastics, widely used in adhesives, coatings, etc., also known as artificial resin, artificial resin, resin glue, etc. Artificial resin is a thermosetting epoxy polymer. Propylene oxide and bisphenol A (phenol methane) produce chemical reaction to form, in the preparation process of epoxy resin, need to use curing agent, but, existing curing agent quality is bad, to the preparation of later stage epoxy resin It will have a great impact, and the preparation steps of the existing curing agent are relatively complicated, so the cost is high, which is not conducive to widespread promotion. Contents of the invention [0003] The present invention provides an epoxy resin curing agent and a preparation method thereof in order ...
