The paper reviews the method of creating a new bio-composite material based on birch wood and describes the mechanism of interaction of used motor oil with birch wood by infrared spectroscopy involved. It also provides data on the moisture absorption of the newly obtained composite. Used motor oil has high hydrophobic and antiseptic properties. The main chemical changes in oils occur as a result of its oxidation during engine operation under the temperature influence. However, the spectrum of spent engine oil is distinguished by the appearance of three new peaks: the wide peak of 3600-3000 cm⁻¹, which is formed during characteristic vibrations of the OH group, indicating water cut in the engine oil, a narrow peak of 1740 cm⁻¹, characteristic of stretching vibrations of the carbonyl group (C = O). In addition to these peaks, the other peak was detected at the 1150 cm⁻¹ frequency and, yet, another weakly pronounced peak of 970 cm⁻¹, which correspond to stretching vibrations of the peroxide group (C-O-O). The mechanism for impregnating wood with used engine oil has been developed. The moisture absorption of wood impregnated with spent engine oil is 3 times less than that of natural wood.

本文回顾了基于白桦木创建新型生物复合材料的方法，并通过所涉及的红外光谱描述了废机油与白桦木相互作用的机理。它还提供了新获得的复合材料的吸湿性数据。用过的机油具有很高的疏水性和防腐性。机油的主要化学变化是由于在发动机运行期间受温度影响而发生氧化的结果。然而，用过的机油的光谱通过出现三个新峰来区分：3600-3000 cm ^-1的宽峰，这是在 OH 基团的特征振动期间形成的，表明发动机油中含水，一个窄峰1740 cm ^-1的峰值，羰基伸缩振动的特征（C = O）。除了这些峰之外，在1150 cm ^{-1频率处检测到另一个峰，然而，在970 cm -1}处检测到另一个弱显着峰，其对应于过氧化物基团(COO)的伸缩振动。已开发出用旧机油浸渍木材的机制。用废机油浸渍的木材的吸湿性比天然木材低3倍。
