Influence of Shungite Modificator on Technological Properties of Polymeric Glue Based on Urea-Formaldehyde Resin

Abstract:

Previously it has been experimentally established that modification of polymeric glue on the basis of urea-formaldehyde resin by adding shungite powder leads to improvement of physical-mechanical properties of wood-particle boards. The goal of the investigation was to establish the influence of the shungite powder, consisting of particles in the size from 50 to 100 nanometers, on such technological properties of glue, as duration of gelatinization and viscosity. It was established: the shortest duration of gelatinization for glues was achieved with shungite addition of 10%; the lowest viscosity depends on the composition of the glue and was achieved with shungite addition from 5 to 10%.
