Abstract

 surface modification with natural modifiers containing chemical bonding agents including rosin maleic can improve the physical properties of wood by reducing the number of hydroxyl groups. It is likely that an increase of temperature or the presence of a catalyst will have a more desirable effect on the physical properties of the wood by improving the hydroxyl group’ s substitution of the wood cell wall. This study was conducted to investigate the effect of different temperature levels and the presence of Aluminum chloride catalyst for applying surface modification with rosin maleic, and evaluating the efficiency of the modification on the physical properties of Spruce wood. The samples were immersed in a rosin maleic solution with a concentration of 40% by weight/ volume (in toluene/xylene solvent) for 24 hours, and were heated for determine the effect of temperature, catalyst and leaching, under two temperature levels of 60° C, with and without catalyst, and 140° C, for 4 hours. According to the results, modification by reducing the hydroxyl groups (based on the infrared spectrums), improved hydrophobicity and dimensional stability of the treated samples. At the end of water immersion period, the higher temperature of reaction with formation a more stable structure against hydrolysis, led to maintenance the weight percent gain of modification. Increasing the modification reaction temperature from 60° C to 140° C create a significant difference in the measured properties, but the presence of the catalyst in the modification at 60° C reduced this difference and formed more stable structures. In a general conclusion, it can be claimed that the use of Aluminum chloride as a catalyst in modification with rosin maleic, makes possible applying surface modification at ambient temperature, by forming a more stable structure against hydrolysis.
