| titleOfInvention | The preparation method of high absorbency PVC plastic film |
| abstract | The invention discloses a kind of preparation methods of high absorbency PVC plastic film, belong to PVC film field, include the following steps: calendering process, pass through after PVC plastic film rolling and drawn by deflecting from roller；Embossing processing, deflects from the embossing processing of film of roller extraction, and wherein upper roller uses knurling rolls, and lower roll is rubber rollers, and the film after embossing enters next procedure through temperature refining wheel group again；Cooling treatment, cooling using five rollers, temperature is followed successively by 180~200 DEG C, 180~200 DEG C, 180~200 DEG C to five rollers from front to back；190~210 DEG C, 150~170 DEG C；Packaging is batched, film after cooling is batched into packing, high ink-receptive film required for obtaining.The beneficial effect of this patent is: cooling using five rollers, wherein most latter two chill-roll temperature is controlled, there is certain temperature difference, PVC film temperature decrease after making embossing, to make PVC film surface slight shrinkage occur, surface texture is even closer and smooth, to improve its surface tension. |
