压敏涂料的制备及性能研究

Study on Preparation and Properties of Pressuree-sensitive Paints

以三(4,7-联苯-1,10-邻菲啰啉)二氯化钌复合物为探针分子,氟硅改性丙烯酸树脂为黏合剂制备了压敏涂料。研究了不同单体配比制备的树脂、不同浓度的探针分子以及不同的施工工艺参数对压敏涂料发光性能的影响,同时还考察了在-20~150℃的温度范围和10~200 kPa的压力范围下,压敏涂料的发光强度的标定曲线。结果表明:当压力处于负压时,标定曲线的斜率较大,压力敏感度大;当压力处于正压时,标定曲线的斜率降低,压力敏感度变弱。

The pressure-sensitive paints were prepared by using tris-(4,7-diphenyl-1,10-phenanthroline)ruthenium(Ⅱ)dichloride complex as the probe molecule and fluoro-silica-modified acrylic resin as the adhesive.In this paper,the effects of different monomer radios for resin preparation,different concentrations of probe molecule and different construction parameters on the luminescence properties of pressure-sensitive paints were studied.The calibration curves of luminescence intensity of pressure-sensitive paints were also investigated in the temperature ranges of-20~150 C and the pressure ranges of 10~200 kPa.The results indicated that when the pressure was under negative pressure,the calibration curve exhibited a steeper slope,indicating a higher pressure sensitivity.Conversely,when the pressure was under positive pressure,the slope of the calibration curve decreased,indicating a weaker pressure sensitivity.
