摘要:
为改善聚对苯二甲酸丁二醇酯(PBT)的激光标记效果,通过将二氧化锡(SnO2)分散在PBT熔体中制备PBT/SnO2材料,经激光辐照处理,在材料表面产生清晰的激光标记图案。通过肉眼观察和显微分析发现,与纯PBT相比,PBT/SnO2材料在激光辐照后具有较高的标记对比度和边缘锐度,取决于SnO2加入量和激光功率参数。此外,在不同激光功率条件下考察了PBT/SnO2材料表面产生的二维码(QR)的标记质量和机器可读性。使用扫描电镜(SEM)、X射线衍射(XRD)、拉曼光谱、热重分析(TGA)和示差扫描量热仪(DSC)对激光标记表面进行表征分析。结果表明PBT/SnO2材料表面激光标记的形成是由于SnO2颗粒吸收1 064 nm波长激光的辐射能量,使颗粒周围PBT分子链局部受热发生热解炭化,从而导致无定型黑色碳类物质的生成,过程中没有发生SnO2晶型结构的变化。
Abstract:
High quality laser markings can be easily produced on surfaces of poly(butylene terephthalate)(PBT)by simple dispersing stannic oxide(SnO2)in PBT melt, and followed by a laser irradiation procedure in order to improve the laser marking performance of PBT. Compared with the pure PBT sample, the PBT/SnO2 samples after the beam-controlled laser irradiation showed higher marking contrast and edge acuity, depending on the SnO2 loading content and laser power in terms of the visual observations and microscope analysis. In addition, the marking quality and readability of the laser markings for the industrial use as the two-dimensional quick response(QR)codes were tested for the PBT/SnO2 material under various laser power condition. The laser irradiated material surfaces were characterized by using SEM, XRD, Raman spectroscopy, TGA and DSC. The results indicated that the formation of the black-colored marks on sample surfaces was due to the laser absorption at the irradiation wavelength of 1 064 nm by the SnO2 particles and localized heating of the surrounding PBT chains, leading to the generation of the amorphous black carbonized materials without changing the crystal structures of SnO2.
