TPNR Membrane Reinforcing with Cotton Fibre Spun

Reinforcement of TPNR （thermoplastic natural rubber） with cotton fibre spun was prepared by using hot compression moulding. The TPNR was prepared by mixing NR （natural rubber） with PE （polyethylene） using 2-roll mills before compressed on cotton fibre spun and vulcanized at 150℃. The mechanical properties and morphology of the membrane were investigated using DMTA （dynamic mechanical thermal analyzer） and SEM （scanning electron microscopy）, respectively. The membrane strength was increased from 10 MPa to 18 MPa after reinforced with cotton fibre spun as well as the increasing of dielectric constant. The membrane was immersed in xylene to remove PE phase before characterization of membrane properties.
