N2 - One kind of heat resistant and high bonding strength of reactive hot melt polyurethane adhesive (RHMPA) was successfully synthesized using a two-step bulk polymerization with 4, 4′-diphenlymethane diisocyanate (MDI), poly(tetramethylene glycol) (PTMG), and 1, 4-butanediol (1, 4-BDO). The effect of RHMPA chain extended at different time and temperatures on adhesive performance was studied by single lap shear strength and tensile strength of butt joints. The results showed that the bonding strength increased with the chain extending reaction time and temperature. Moreover, the higher the reaction temperature, the increasing trend of butt bond strength was more obvious. In addition, the influence on adhesive performance of the RHMPA dealed with hydrochloric acid solution, NaON aqueous solution, hot water at 80°C, high and low temperature were also investigated. The results showed that the bonding strength of the RHMPA almost unchanged and exhibited an excellent chemical resistance to these conditions.
