摘要
以耐热温度200℃以上的聚-4-甲基-1-戊烯(TPX)树脂为原料,通过热挤出涂布机淋膜复合制备离型层,探索纸膜结合强度较好时的热挤出涂布工艺条件。结果表明,采用DX820 TPX树脂为原料,挤出涂布的5段适宜温度分别为250℃、280℃、305℃、305℃和305℃,达到最佳纸膜结合强度的其他工艺条件为:螺杆转速40 r·min-1、电晕功率0.8 kW、气隙高度55 mm、压区压力700 kPa;纸膜结合强度达到0.46 kN·m-1,纸膜结合良好。
Poly（4-methyl-l-pentene） TPX resin which has high temperature over 200℃ resistance was taken as raw material to make coating by extrusion coating process. It＇s the first time to carry out this research in China, while this investigation is to explore the main process parameters of extrusion coating when release paper prepared has good adhesive strength of coating and base paper. It showed that when DX820 TPX was taken as raw material in this experiment, appropriate extruding temperature was 250℃,280℃, 305℃., 305℃ and 305℃, the main process parameters of extrusion coating was screw speed 40 r＇min 1, corona power 0.8 kW, air gap height 55 ram, nip pressure 700 kPa so as to get good adhesive strength of coating and base paper of 0.46 kN＇m 1.
