摘要：
To investigate the improved performance of silane coupling agents on starch-based wood adhesive, we prepared adhesive samples using gamma-Methacryloxypropyl trimethoxy silane(KH570) as a cross-linking agent. The results found that the addition of KH570 resulted in enhanced shear strength and storage stability. The addition of KH570 also promoted the thermal stability due to increase the number of covalent bonds. Furthermore, the KH570 enhanced the shear-thinning property and weakened the pseudoplastic behavior of the adhesive. The characterization of copolymers was carried out via Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD) and thermal analysis. The performing XPS analysis and morphological structures of adhesive were evaluated by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). In conclusion, 6% KH570 (1d-1570:starch, w;w) could be used to prepare starch-based wood adhesives with superior performance and stability. (C) 2017 Elsevier B.V. All rights reserved.
