Abstract:

The formation process of InterpenetrationPolymer Network (IPN) base on poly blend polyurethane (PU)-SIR-5 Natural Rubber (NR) which assisted montmorillonite (MMT) as a filler was carried out.The PU was synthesized by mixingpolypropylene glycol and toluene diisocyanates (mole ratio 2: 1). NR was vulcanised by adding stearic Acid, zinc oxide, MBTS and sulfur, respectively. PU was mixed with NR at 140^oC to generate IPN PU-NR. Then, IPN PU-NR- MMT composite may be produced by adding MMT. The IPN PU-NR-MMT composite was characterized by Tensile Strength Test, Water Absorption Test, SEM, FTIR and DSC, respectively. The results showed that a mixture of IPN composites increased with increasing MMT and its good elongation. Mechanical properties, physical and IPN composite morphology is influenced by the amount of MMT. It causesthere is a cross linking each other at the bond interface.
