目的 为了解决无底纸不干胶标签打印机传纸结构防粘性差导致传纸不畅的问题。方法 主要从传纸通道和胶辊的材质入手，选择硅橡胶、PTFE板、硅油纸、PP/PE混合塑料、PE塑料、玻璃纸、OPP和OPC混合塑料等多种材料，测试其防粘性能，从而优选出适用于无底纸热敏打印机传纸系统材质。通过测试常温下材料的接触角、粗糙度及剥离力，并对比分析与防粘性能的关系，综合得出材质的防粘性能评价。结果 硅橡胶和硅油纸相对于PTFE等材质，其综合防粘性能较好，接触角都在110°以上，剥离力在0.16 N以下。结论 考虑到表面强度和使用寿命问题，硅橡胶材质更适用于无底纸热敏打印机胶辊材质，而硅橡胶和PTFE材质较适合于传纸通道材料。

The work aims to solve the sticky problem caused by the poor anti-sticking properties of paper transferring structure in the bottomless adhesive label printer. Considering the material for the paper passageway and the rubber roll, a variety of materials such as silicone rubber, PTFE, silicon oil paper, PP/PE mixed plastic, PE plastic, glass paper, OPP and OPC mixed plastic were selected and tested for anti stickiness property, so as to select the suitable material for the no backing sheet portable thermal printer. By testing the contact angle, roughness and peeling force of the material at room temperature, and comparing and analyzing the relationship with the anti sticking property, the evaluation of anti sticking performance for these materials was obtained. Silicone rubber and silicone paper had better anti sticking properties, compared with PTFE, and had contact angle above 110° and the peeling force below 0.16 N. However, considering the surface strength and service life, the silicone rubber is more suitable for the paper roller and paper passing material for the no backing sheet portable thermal printer.
