第一步:由放卷机进行PET基材供卷;
第二步:将配比好的粘合剂通过双辊滚涂机均匀的涂覆于PET基材的一侧表面;
第三步:将第二步中带涂覆粘合剂的PET基板输送至烘房中进行烘干固化,烘干温度为70~180℃,烘干时间为5~10分钟;
第四步:在带有粘合剂的PET基材料表面复合一层耐水解处理涂层;所述耐水解处理涂层为含有高氟合晶型氟涂层,所述耐水解处理涂层的厚度为50~150μm;
第五步:将第四步中复合耐水解处理涂层的PET基材卷于纸芯上形成半成品进行晾置,晾置时间为2~7天;
第六步:利用配比好的粘合剂通过双辊滚涂机均匀的涂覆于第五步所得PET基材的另一侧表面;
第七步:将第六步中带涂覆粘合剂的PET基板输送至烘房中进行烘干固化,烘干温度为110~195℃,烘干时间为8~15分钟;
第八步:在带有粘合剂的PET基材料表面复合一层涂覆层;所述涂覆层为三氟氯乙烯或聚偏氟乙烯的微小颗粒与基础树脂混合形成的涂覆材料;
第九步:将第八步所得PET基材卷于纸芯上形成成品背板进行晾置,晾置时间为3~6天;
第十步:将第九步所得背板根据客户需求进行切边、分卷;
第十一步:对第十步所得背板进行抽样检测,检测背板的性能及质量等级。
