Low Temperature Shape Memory Thermosetting Epoxy, Film Material and Producing Method Thereof

摘要

A low temperature shape memory thermosetting epoxy has a epoxy, a curing agent, a modifying material and a functional material. The curing agent is fatty amine, polyamide and aromatic amino compound. The modifying material is polyester polyol, polyether polyol, aromatic diamine, and silicon compound. The functional material is boron trifleoride, terminal carboxyl group, calcium carbonate, pigment, and mixture thereof. Thus, the present invention provides an epoxy that is deformable and is shape memorable under room temperature.

主权项

1. A producing method of a shape memory thermosetting epoxy having steps of:
mixing a modifying material and a cross-linking agent to form a pre-polymer; mixing epoxy, the pre-polymer and a functional material to form a major blending agent; mixing a curing agent with the major blending agent to form a fluid shape memory thermosetting material; molding the fluid shape memory thermosetting material as a required shape; wherein the cross-linking agent is first added to activate a cross-link reaction with the major blending agent; and the curing agent then added to terminate the cross-link reaction.
