Problems solved by technology

[0002] The existing ordinary PVC calendered film does not meet the requirements of elasticity and wear resistance in actual use. Although TPU polyurethane elastomer material is added to the formula for modification, due to the addition of elastomer in the production process, the torque in the plasticizing stage increase, it is necessary to modify the original equipment and process flow, so in addition to increasing the power of the internal mixer, this patent changes the original open mill process and uses the twin-screw extruder process instead

Description

technical field [0001] The invention belongs to the field of chemical industry, and more specifically relates to a production process of a high-elastic and wear-resistant rolling film. Background technique [0002] The existing ordinary PVC calendered film does not meet the requirements of elasticity and wear resistance in actual use. Although TPU polyurethane elastomer material is added to the formula for modification, due to the addition of elastomer in the production process, the torque in the plasticizing stage Increase, need to carry out transformation to original equipment and technological process, so this patent except increasing the power of internal mixer, changes original open mill process and uses twin-screw extruder technological process instead. Contents of the invention [0003] The purpose of the present invention is to provide a high-elastic wear-resistant calendering film production process, the process flow is scientific and reasonable, the material reac...
