Study on the Mechanism of the Soybean Adhesive Improved by Micro/Nano Fibrils and the Bond Strength of the Poplar Plywood with it

Abstract:

The micro/nano fibrils was used to modify the soybean glue, which was used as the adhesive of poplar plywood. The poplar plywood bond strength were evaluated. To explain the improvement in mechanism, Differential Scanning Calorimetry(DSC) and Dynamic Mechanical Analysis apparatus(DMA) were applied to analyze the influence of poplar macro/nano fibrils on soybean glue. The test of bonding strength results show that the bond strength of poplar plywood was enhanced as micro/nano poplar fibrils was added. And the DMA figures of soybean glue illustrate that poplar macro/nano fibrils has improved the deformation resistence of soybean glue plywood and the heat resistance of soybean glue.
