The effects of reinforcing resin on the compatibility,processability,vulcanization characteristics of natural rubber/polyvinyl chloride(NR/PVC)system and the physical properties of foaming materials were studied.The results indicate that reinforcing resin is an effective compatibilizer for NR/PVC system to achieve the blending of NR and PVC.At the same time,it can improve the processability of the rubber material,shorten the Mooney scorch time of the rubber material,and increase the hardness of the vulcanized rubber.The foaming material prepared with 8 parts reinforcing resin has the best performance,with a smooth surface,uniform pore size,and the lowest thermal conductivity.
