Abstract:

This research aims to find out the improvement of SPI adhesive by methanol, SDS and urea.The results showed that with the increase of methanol content, the bonding strength increased firstly and then decreased, when the methanol content accounted for 15% of the total mass fraction, the bonding strength was the best. A contrast test of the reaction order was showed that the strength of the dry bonding was slightly decreased, and the wet bonding strength was improved.The optimal reaction order of bonding strength was SDS, methanol and urea DSC, SEM image and IR image analysis results showed that more two level structure of protein was improved, and the same was true of bonding strength. The modified soybean protein glass transition temperature decreased, thus reduced the hot pressing temperature. The protein adhesives not only can adapt to large-scale industrial production but also -saving resources
