Properties of Reactive Hot Melt Adhesives Modified by Polyurethane Containing PEG Segment Intercalated in Sodium Montmorillonite
Source abstract
Abstract
An additive of reactive hot melt adhesive (RHMA), thermoplastic polyurethanes (TPUs) was modified with neat sodium montmorillonite (Na-MMT) or Na-MMT intercalated with poly(ethylene glycol) (PEG), and their effects on the adhesion, rheological, and mechanical properties of RHMA were examined. The neat Na-MMT or Na-MMT intercalated with PEG (Na-MMT/PEG) effectively reduced the set time of RHMA, although the contents of neat Na-MMT or Na-MMT/PEG were less than 0.2 %. The increase of complex viscosity and pseudo-solid like behavior observed at low shear rate indicated that there were intimate interactions between RHMA molecules and neat Na-MMT or Na-MMT/PEG.
