Abstract
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.
Claims12
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.
A shape memory thermosetting epoxy having a modifying material, a polyamine cross-linking agent, epoxy, a functional material, and a curing agent;
- wherein
- the shape memory thermosetting epoxy is deformable at certain range of temperature and is shape memorable under room temperature;
- the cross-linking agent activates a cross-link reaction of the shape memory thermosetting epoxy;
- and
- the polyamine curing agent acts like an inhibitor then terminates the cross-link reaction of the shape memory thermosetting epoxy.
A film material comprises a modifying material, a polyamine cross-linking agent, epoxy, a functional material, and a curing agent;
- wherein
- the film material is able to deform in certain range of temperature and is shape memorable under room temperature;
- the cross-linking agent activates a cross-link reaction of the film material;
- and
- the polyamine curing agent acts like an inhibitor then terminates the cross-link reaction of the film material.
