Abstract :
 

In this research was studied the possibility of using materials containing lignin as effective casting binders, as an alternative to phenolic resins. The main materials containing lignin in the carried out studies, accepted technical lignosulfonates (TLS). It is considered the genesis of their properties in a retrospective of changes in the manufacturing of plant materials. In the research were studied the ways to improve their quality, stability properties, and bonding ability, which are achieved by modifying them with surface-active substances and / or high-energy mechanical processing methods. This treatment increases the binding ability of the material from 0.03 MPa % to 0.5 MPa %, which is comparable with phenolic-based resin binders.
