FIELD: chemistry.
SUBSTANCE: invention relates to a system of reagents for extracting paint materials from recycled water, based on acrylic, melamine, polyurethane, nitrocellulose, epoxy and alkyde film-forming agents and can be used in wood processing, machine building, motorcar and other industries. Disclosed is a flocculant consisting of (wt %) polyacrylamide (6-10), activating additive selected from aminotriazole, guanidine carbonate and semicarbazide (0.1-1.5), hydrazine hydrate (0.1-1.5) and water (the rest).
EFFECT: possibility of varying the structure of the obtained deactivated wastes of paint materials, which enables processing of paint material wastes for reuse or recycling with minimum expenses.
