MODIFIED PHENOLFORMALDEHYDE RESIN

摘要

FIELD: polymeric resins. SUBSTANCE: developed glue composition is based on phenolformaldehyde resins with reactive filling agents of aluminosilicate nature. Composition ensures to improve indices of wood-fibrous plates, decrease inflammability and their toxicity. Modified glue provides adsorption of aromatic hydrocarbon, free phenol and formaldehyde up to 0.03% and 0.06% (as compared with 0.18% in prototype). EFFECT: enhanced quality of resin.
