EBM – new, ecological lignocellulosic composite
Development project funded by the National Centre for Research and Development.
The Wood Technology Institute in Poznan was granted funding by the National Centre for Research and Development for implementation of the project no. N R15 0076 06/2009 entitled:
“New construction material - ecological wood-based nanocomposite of enhanced fire and water resistance,
produced in energy efficient manufacturing process”
Duration of the project: 1.08.2009-28.02.2013
The planned interdisciplinary research was carried out in close cooperation with the industry – company Sp. z o.o. Silikony Polskie (Polish Silicones) and "Sklejka-Pisz" Factory.
The conducted industrial research was aimed at understanding the relationship between the parameters of production and properties of the material providing the basis for production technology. As part of the project new adhesives based on inorganic polymers were developed, and used with wood of various tree species to create ecological nanocomposite of increased fire and water resistance, and resistant to biotic factors. The basic research was focused on nano-modification of wood by infiltration with nanosilica, hydrosol, and lysins and by sol-gel processes. Bitmaps of the chemical composition of nanocomposites with an algorithm for rapid assessment of the percentage of this composition were developed and the relationship between the viscosity of the silicone and the depth of its penetration into wood was determined.
To visualize the microstructures of the obtained composites a scanning transmission X-ray microscopy and a tomographic microscope were used.
The result of the project is a new, original construction material in the form of an eco-friendly wood-based nanocomposite with increased fire, water, and biotic resistance, produced in a process that is environment-friendly – an ecological EBM (Ekologia, Budownictwo, Meblarstwo - Ecology, Construction, Furniture) lignocellulosic composite.
The ecological nanocomposite, unlike the vast majority of wood-based materials currently offered, does not contain formaldehyde and any compounds harmful to the environment and human health, which was confirmed by the results of VOC tests carried out by an accredited laboratory. The new material is completely resistant to microbiological decomposition and flame retardant. The durability of the board and its resistance to moisture, depending on the technological variant, may vary, in some cases it is even higher than required in standards EN 312:2011 for all types of particle boards (P2-P7) and EN 300:2007.
The formaldehyde-free composite is an innovative wood-based board with many applications in construction and furnishing such interiors as: kindergartens, schools, hospitals or public facilities.
The research work on this trailblazing invention ended with patent applications in the Patent Office of the Republic of Poland under numbers P. 394926 of 18.05.2011 and P-402922 of 26/02/2013.
A nanocomposite based on a lignocellulosic structure, silicone polymers, and nanosilica can become an innovative product that meets scientific and social trends in the European Union economy, thus contribute to the competitiveness of the domestic wood-based panels industry.
The invention has already been presented and appreciated at many exhibitions, both domestic and international.
