附图说明
为了使本发明的内容更容易被清楚地理解，下面根据具体实施例并结合附图，对本发明作进一步详细的说明。
图1是本发明所述的PVC输送带生产工艺流程图。
具体实施方式
本发明所述的一次性成型PVC轻型输送带，包括作为输送带骨架的织物，包括织物，所述织物的表面涂覆有打底层，其中一个织物正面打底层上涂覆有面层，形成PVC面层布，该织物反面打底层通过贴合层与另一个织物正面打底层贴合，构成所述PVC轻型输送带。。
其中，所述面层按质量份计：邻苯二甲酸二异壬酯(DINP)70kg、糊树脂R-13粉20kg、糊树脂P440粉30kg、糊树脂P450粉30kg、钙锌稳定剂(GZ)3kg、酞菁绿(G)2kg、中铬黄(103)3kg。
所述贴合层按质量份计为：邻苯二甲酸二异壬酯(DINP)85kg、糊树脂P440粉60kg、糊树脂P450粉30kg、钙锌稳定剂(GZ)3kg、酞菁绿(G)3kg，中铬黄(103)5kg。
所述正面打底层按质量份计为：邻苯二甲酸二异壬酯90kg、糊树脂R-13粉70kg、糊树脂P440粉30kg、糊树脂P450粉30kg、钙锌稳定剂(GZ)5kg，PVC粘合剂5kg。
所述反面打底层按质量份计为：邻苯二甲酸二异壬酯(DINP)90kg、邻苯二甲酸二辛酯(DOP)20kg，糊树脂R-13粉70kg、糊树脂P440粉30kg、糊树脂P450粉30kg、钙锌稳定剂(GZ)5kg，PVC粘合剂5kg，钛白粉3kg。
织物正面打底采用高粘度的打底层浆料，反面打底采用相对正面低粘度的打底层浆料，在正面打底浆料的基础上加入增塑剂邻苯二甲酸二辛酯(DOP)，可以使粘度降低。这样打底使PVC打底料更加渗入布缝中，把布缝垫平，减少料与布的汽泡及剥离强度。
厚织物选择型号8018G的大理石布，此布经过几次验证最终在确定此布的织法，经线：强度1400N/CM、纤度1670分特，纬线：强度770N/MM，纤度2200分特，其强度高、耐磨性好，其他浆料的原材料是选耐磨PVC糊树脂、环保增塑剂、环保稳定剂和耐高温颜料等，材料均为环保型的。
本发明采用的是一条整体生产流水线设备，工作流程为：流水线开始放卷-经大牵引-涂层刀架-前后烘箱(烘箱Ⅰ、烘箱Ⅱ、烘箱Ⅲ)、经贴合滑辊-到大牵引-收卷。
上述一次性成型PVC轻型输送带的制备方法，其步骤为，
S1、配备浆料：分别按上述打底层、面层和贴合层的质量份计，分别将所需物质混合搅拌均匀，并真空脱泡，分别得到正面打底浆料、反面打底浆料、面层浆料和贴合浆料；
S2、烘布：将用于制备轻型输送带的织物进行热定型处理；
