Research of the Physicochemical and Mechanical Properties of Composite Materials Based on Lignosulfonates

The increasing pace of construction in Russia and increasing environmental requirements for building materials lead to the need to search for new solutions for the creation of unique materials and the involvement of additional resources. The analysis of scientific and technical literature and laboratory studies have shown that lignosulfonates can be one of the promising sources of raw materials for the production of composite building materials. In this regard, the work investigated and substantiated a method for producing composite materials based on lignosulfonates. It was found that in the obtained compositions, lignosulfonates act as both a hardener and a dispersed filler. Thermogravimetry proved that the obtained compositions are thermally stable. The results of the study of the physicochemical and mechanical properties of the obtained samples showed that lignoepoxy composite materials can be an alternative replacement for known industrial analogues.
