Amine-based epoxy resin curing agent powder is a chemical curing agent primarily composed of amine compounds. Compared to traditional phenolic resins and imidazole compounds, it exhibits higher reactivity and faster reaction speeds. It can rapidly undergo chemical reactions with epoxy resin at room temperature, forming a stable cross-linked network to achieve material hardening and curing.
II. Preparation Process of Amine-Based Epoxy Resin Curing Agent Powder
The preparation process of amine-based epoxy resin curing agent powder is relatively straightforward but requires strict control of reaction conditions to ensure stable performance. First, amine compounds are mixed with epoxy resin through heating or mechanical stirring. A catalyst (e.g., acid anhydride compounds) is then added to promote the curing reaction. Finally, the mixture is ground into a powdered form to obtain the final product.
