Producing of Organomineral Filler on the Basis of Wooden Bark and Basalt for Development of Composite Materials

Possibility and basis of technology of reinforcing of wooden bark by basalt for obtaining a filler for structural heat insulation are considered. As a filler, it is proposed to use the bark of Scots pine (Pinus silvestris L), obtained from the dump of the lumber factory, and basalt sifting – waste of mineral wool production. Optimal dimensional characteristics of raw materials were selected. True density, coefficient and time of swelling, optimal composition of test samples were defined. Conclusions regarding the influence of time of wooden bark dispersion on its porous structure were drawn. Data about surface, sizes and amount of pores in the dry milled bark before and after the process of reinforcing by nano-sized particles of basalt were obtained. Fundamentals of technology, quality control and effective ways of reinforcing the bark by nano-sized particles of basalt for subsequent using as the filler for structural heat insulation were developed.
