Abstract:
      To solve the issues of time lag and operational complexity in the detection of the Mooney viscosity [ML(1+4) 100 °C] （referred to as Mooney viscosity） of natural rubber （NR） compound，a method for online prediction of the Mooney viscosity of NR compound based on a convolutional neural network （CNN） was proposed.The parameters recorded by internal mixer during the compounding process，such as the chamber temperature，mixing time，material temperature，rotor speed and torque，Mooney viscosity of plasticated rubber were organized into a matrix as input，with the Mooney viscosity of the compound as output，the CNN prediction model for the Mooney viscosity of NR compound with complex mapping relationship from input to output was constructed.The results showed that the CNN prediction model for the Mooney viscosity of NR compound was essentially convergent，with a mean square error of 0.5 between the predicted and measured values of the Mooney viscosity.The correlation coefficient（ R2） of the CNN prediction model was 0.874 3，with a recognition rate of 88.46% for prediction errors within Root number 5 ，and with a recongnition rate of 42.30% for prediction errors within Root number 2.The CNN prediction model demonstrated high indentification accuracy in predicting the Mooney viscosity of NR compounds within the range of 45～75 of Mooney viscosity of plasticated rubber.
