摘要
The self-adhesion strength of natural rubber (NR) compounds modified with phosphorylated cashew nut shell liquid (PCNSL) prepolymer has been studied with respect to variations in contact time, contact pressure, storage time, and concentration of PCNSL. The self-adhesion strength of NR as measured from the 180 degrees peel test showed a maximum at 10 phr of PCNSL. The adhesion between substrates containing various concentrations of PCNSL (from 0 to 20 phr) also reached a maximum at a PCNSL concentration of 10 phr in one of the substrates. An increase in self-adhesion strength with storage time was observed for the PCNSL-modified NR compounds, which is presumed to be due to the time-dependent interfacial diffusion.
