Abstract |
Abstract Hydrophilic reactive hot-melt polyurethane adhesive(HRHA) using a hydrophilic
polyol having different molecular weight and NCO index was synthesized. This
HRHA was synthesized using Polyethylene glycol(PEG) as a hydrophilic polyol, Polypropylene
glycol(PPG) and Polycaprolactone diol(PCL) as hydrophobic polyols, and Methylene
diphenyl diisocyanate(MDI) as an isocyanate. The changes in IR spectrum, viscosity and
thermal properties of HRHA with different PEG molecular weights and NCO index were
investigated, and the tensile strength and elongation of the HRHA casting film and the
peel strength, moisture permeability and water pressure of the HRHA coated fabric were
confirmed. In this experiment, as the molecular weight of PEG and NCO index increased,
the adhesive strength, tensile strength, elongation and moisture permeability was increased
but viscosity and Tg was decreased. |
