Preparation and characterization of a soy protein based bio-adhesive crosslinked by waterborne epoxy resin and polyacrylamide

Abstract

Waterborne epoxy resin mixed with polyacrylamide crosslinked modified soybean protein adhesive.

In situ synthesis of star copolymers consisting of a polyhedral oligomeric silsesquioxane core and poly(2,5‐benzimidazole) arms for high‐temperature proton exchange membrane fuel cells

“…Meanwhile, the [35], while the peak at 2.01 ppm attributed to the secondary ammonia [33,36] and 0.86 ppm to the hydroxyl. At the same time, the peak at 3.21 ppm corresponding to the proton on the epoxy group [36,37] does not appear in the spectrum of POSS-DABA. These indicate the occurrence of the epoxy ring-opening reaction between the epoxy groups in G-POSS and the amino groups in monomer DABA.…”

Renewable bio-based adhesive fabricated from a novel biopolymer and soy protein

“…Recently, a series of chemical modications have been reported to enhance the performance of soy protein adhesives, such as soy protein structural and crosslinking agent modications. 5 Specically, epoxy and melamine resin, polyisocyanate, polyamidoamine-epichlorohydrin (PAE) resin, phenol formaldehyde resin, trimethylolpropane triglycidyl ether (THPTG), and bisphenol-A waterborne epoxy resin and polyacrylamide (PAM), [6][7][8][9][10][11] were applied to enhance the water resistance of soy protein adhesive due to the crosslinked network structure formed by the reactions with the hydrophilic groups (i.e., -NH 2 , -COOH, and -OH) in soy protein molecules. The resulting adhesives meet the interior use requirements but still rely on unrenewable petroleum-based resources.…”

Tuning the Adhesive Properties of Soy Protein Wood Adhesives with Different Coadjutant Polymers, Nanocellulose and Lignin

“…A number of recent studies are concerned with increasing the water resistance of soy protein-based adhesives [64][65][66][67][68]. However, improving the moisture resistance of the adhesive is not the purpose of this study.…”
