Abstract


The paper industry is one of the sources of environment pollution. Therefore, the problem of efficient utilization of such wastes is an urgent one. One of the possible effective methods of paper industry waste recycling can be the application in epoxy composites. The review of literature proves a high scientific and industrial actuality of this thematic. Optical microscopy shows that 20 wt% of micro- and meso-particles of lignocellulose from waste-paper utilization leads to changes in morphology of composite due to interactions between phases. As result, the key mechanic (modulus at bending, resistance to wear) and resistant (swelling, fire- resistance) parameters changed. At the same time, 20wt% filling do not importantly change compression and bending strength parameters. Filled composites (as fresh as aged) are noticeable more resistant in acetone-containing solvents. Effect of filling on resistance in H2O2 depends on its concentration and age of templates: aged 20%-filled composites are more resistant than unfilled (in 35% H2O2), but fresh 10%-filled composite destruct quickly (unlike unfilled) in high-concentrated (60%) H2O2
