Abstract

The invention discloses a palm oil-based underwater adhesive and a preparation method thereof, belonging to the technical field of polymer adhesives. Using palm oil as raw material, palm oil fatty acid ethyl acrylamide was synthesized, blended with isobornyl acrylate, and palm oil-based underwater adhesive was prepared by 405nm ultraviolet light curing technology under the action of photoinitiator . The palm oil-based underwater adhesive prepared by the invention is environmentally friendly and has high tensile strength, tensile elongation at break and underwater bonding strength.

Description

technical field [0001] The invention belongs to the technical field of polymer adhesives, and particularly relates to a light-cured palm oil-based underwater adhesive and a preparation method thereof. Background technique [0002] Underwater adhesives are widely used in industry and medicine. However, the commonly used underwater adhesive is a thermosetting material, because the thermosetting material with a three-dimensional network structure can prevent the water from damaging the bonding performance of the adhesive, but it also causes the bonding performance of such materials to be irreversible; thermoplastic adhesives It has the advantages of repeatable bonding and instant bonding, but such thermoplastic adhesives have the problem of insufficient bonding strength; more importantly, the bonding strength of such adhesives often depends on intermolecular forces such as hydrogen bonds. damaged by water. Based on such problems, the present invention forms hydrophobic protec...
