Abstract:
PVC resin is widely used in medical and other industrial fields because of its good chemical corrosion resistance, wear resistance, low cost and simple production. In this study, the related research progress in the influence of resin polymerization degree, processing technology and processing aids on the mechanical properties of PVC was reviewed, and the influence rules of processing aids on the properties of PVC was analyzed. Relevant research results show that the increase of the resin polymerization degree can increase the strength of PVC, but at the same time reduce the toughness. The use of compression molding process is beneficial to improve the strength and modulus of PVC. The use of injection molding process is beneficial to improve the plasticity and toughness of the PVC. Properly increasing the processing temperature and the blending time can improve the toughness of PVC. Adding heat stabilizers can improve the plasticity, toughness and strength of PVC. Adding plasticizers can improve the strength and toughness of PVC. Adding modifiers can improve the strength and toughness of PVC.
