Abstract

In this study, the Scots pine wood samples were impregnated (single treatment) with boric acid combined with two types of water-based acrylic resin (pure acrylic and semi-translucent acrylic emulsion) to limit the boron leaching and improve the decay resistance. The results showed dimensional stability in anti-swelling efficiency and water absorption improved in wood specimens treated with boric acid and acrylic types. While the leachability was over 90% for only 3% boric acid-impregnated wood (control), it was calculated at 36% for acrylic emulsions-impregnated wood. Although there were no weight losses for the unleached woods, it was up to 9% for leached woods impregnated with acrylic resin and emulsion. The 25% acrylic emulsion had no weight losses after the leaching test for Coniophora puteana and Trametes versicolor. The boric acid combined with acrylic resin can improve the leaching resistance with the synergic effect, enhancing resistance against biological threats.

水性丙烯酸树脂与硼酸对浸出力的协同效应

在本研究中，将硼酸与两种类型的水性丙烯酸树脂（纯丙烯酸和半透明丙烯酸乳液）相结合，对苏格兰松木样品进行浸渍（单次处理），以限制硼的浸出并提高耐腐性。结果表明，用硼酸和丙烯酸处理的木材试样在尺寸稳定性、抗溶胀效率和吸水性方面得到了改善。虽然只有3%硼酸浸渍的木材（对照）的可浸出性超过90%，但丙烯酸乳液浸渍的木材的可浸出率为36%。虽然未经处理的木材没有重量损失，但用丙烯酸树脂和乳液浸渍的浸提木材的重量损失高达9%。25%丙烯酸乳液在对丝兰和云芝的浸出试验后没有重量损失。硼酸与丙烯酸树脂复合可以提高耐浸性，并具有协同作用，增强对生物威胁的抵抗力。
