Abstract:
After being treated with modifier （MF）,the soy protein was grafted with maleic anhydride(MA),and then co-polymerized with styrene(St) to prepare bio-adhesive,the original viscosity and its water-resistant bonding strength(WRBS) of the adhesive were investigated respectively,the optimal synthesis conditions are concluded as: 15g SPI, 6.5%(compared with that of SPI) MF, 3.0 g MA, 20 mL St, 0.05g/(1mL St)initiator,reaction temperature 70°C。With the increase of the dosage of SPI,the viscosity of the adhesive will be accordingly increased and WRBS increases dramatically at first and then slowly；increasing the dosage of the modifier will make both the viscosity and WRBS decrese first and then increase;when 1.5g MA is added,the adhesive has the least viscosity ,while it has the most one when 4.5g MA is used,WRBS of the adhesive will increase first and then decrease dramatically with the increasing dosage of MA;though the effect of the dosage of St on the viscosity of the adhesive is complicated,the adhesive will have the greatest WRBS of 2.78 MPa when 20 mL St is used;as the initiator is regarded,0.05g initiator in 1mL St makes the viscosity have the greatest WRBS of 2.79 MPa,and the viscosity is only 12MPa·S in this situation,which has little effect on the coating process.
