A series of waterborne polyurethane adhesives (WPUAs) were prepared from diphenylmethane-4,4 0 -diisocyanate (MDI), 1,6-hexamethylene diisocyanate (HDI), poly(1,4-butanediol adipate) diol (PBA), 1,4-butanediol (BDO), and internal-emulsifying agents by the prepolymer mixing method. The viscosity, mechanical properties, thermal properties, and adhesion strength of the samples were measured. The structure-property relationship was discussed primarily. The results indicated that the MDI/HDI and PBA/BDO molar ratio influenced these properties. The WPUA exhibited excellent T-peel strength and mechanical properties at a suitable MDI/ HDI (or PBA/BDO) molar ratio. Moreover, higher MDI/ HDI (or PBA/BDO) molar ratio resulted in higher thermal stability.

“…Compared to the prepolymers, the molecular weights of the chain-extended poly(urethane urea)s (PUUs) were approximately twice as high. Compared to the conventional chain-extended PUU dispersions [35][36][37], these M n values are still rather low. The M n(PUD) values seem to increase with decreasing DDI/EELDI molar ratio.…”

“…The adhesion agent is needed to fabricate composites in hot press molding . Aqueous adhesives, such as acrylic, polyurethane (PU), epoxy etc., are able to substitute for solvent adhesives because of their exceptional environmental friendly, nontoxic, nonflammable, and high solid content, which are widely used in the fields of building, packaging, and transportation . K. Hasan et al prepared the luffa/epoxy resin composite to test the sound absorption property by using a hydraulic press.…”

Sisal fiber (SF) and waterborne polyurethane adhesive were used to prepare SF-based sound absorption material through hot press molding. SF with elastic polyethylene (PE) film interlayers was also fabricated as a new type of sound absorbing composite. The effects of SF treatment methods and PE film on sound absorption coefficient were evaluated. The alkaline-treated SF composite had higher sound absorption as compared with the untreated SF composite when the sound wave was below 5500 Hz. The sound absorption peak of alkaline/oxidation-treated SF composite moved towards low-and middle-frequency regions. The SF/PE film composite showed that at lowfrequency the more layers of PE film inserted the better sound absorption property. The mass-temperature relationship and FTIR of the composites were discussed. The SF surface and the cross section of the composites were observed by SEM, which showed the void structure and microfiber contributed to enhancing sound absorbing property. POLYM.
