Increasing the Thermal Stability of Wood-Based Materials

Wood-based materials are widely used in modern construction technologies as part of the concept of biopositive construction related to the design and construction of buildings, taking into account the impact on human health and well-being, as well as on the ecosystem as a whole. The main disadvantage of bio-positive wood materials, like any organic materials, is their high flammability. In this regard, improving the thermal stability of wood materials and, as a consequence, reducing their combustibility is a very urgent task. The purpose of the research described in the article was to study the possibility of increasing the thermal stability of wood materials and, as a consequence, reducing their combustibility. As a result of conducted active experiment and statistical processing of its results, the optimum flow rate of flame retardant and substrate moisture content were established. To determine the kinetic parameters of the thermal decomposition process of cellulose materials of different chemical composition (integral method), a Du Pont-9900 automated modular thermal analyzer system was used. As a result of studies it was found that boron-nitrogen wood surface modifiers stabilize lignocarbohydrate complex of wood at the stage of flame burning (the second temperature interval) and significantly reduce the value of weight loss of the substrate at this stage.
