ABSTRACT

Ethyl cyanoacrylate polymerizes at room temperature, and is often used as an adhesive in many areas for a wide variety of applications. In this study, the possibility of using poly(ethyl cyanoacrylate) in the field of wood modification was investigated. For this purpose, Scots pine (Pinus sylvestris L.) and Oriental beech (Fagus orientalis) samples were impregnated with poly(ethyl cyanoacrylate) that was synthesized using acetone. Modified samples were characterized by Thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), and Scanning Electron Microscopy (ESEM). Decay performance was done with white rot fungus (Trametes versicolor (L: Fr.) Pilat. (FFPRI 1030)) for beech wood and brown rot fungus Coniophera puteana for pine wood; the European standard EN113 FTIR analysis indicated that PECA could appreciably alter the chemical structure in modified wood. Thermal changes in modified wood were be minor compared to those of untreated wood. Samples treated with PECA had significantly lower mass losses than untreated samples as a result of fungal exposure to Coniophora puteana and T. versicolor.

摘要

氰基丙烯酸乙酯在室温下聚合，通常在许多领域用作粘合剂，用途广泛。在这项研究中，研究了在木材改性领域使用聚（氰基丙烯酸乙酯）的可能性。为此，将苏格兰松 ( Pinus sylvestris L.) 和东方山毛榉 ( Fagus orientalis ) 样品浸渍在使用丙酮合成的聚（氰基丙烯酸乙酯）中。改性样品通过热重分析 (TGA)、傅里叶变换红外光谱 (FTIR) 和扫描电子显微镜 (ESEM) 进行表征。腐烂性能是用白腐真菌（Trametes versicolor (L: Fr.) Pilat. (FFPRI 1030)）对山毛榉木和褐腐真菌Coniophera puteana 进行的用于松木；欧洲标准 EN113 FTIR 分析表明 PECA 可以明显改变改性木材的化学结构。与未经处理的木材相比，改性木材的热变化较小。由于真菌暴露于Coniophora puteana和T. versicolor ，使用 PECA处理的样品的质量损失明显低于未处理的样品。
