FIELD: chemistry.
SUBSTANCE: invention relates to obtaining glues based on phenolfirmaldehyde resins, used in wood-processing industry in manufacturing chipboards. Glue composition includes finished water-soluble phenolformaldehyde resin SFZh-3014. In the process of mixing modifying additive, which includes 100 wt.p. of furfurolacetone monomer FA and 5 wt.p. of toluenesulphonic acid, is additionally introduced.
EFFECT: creating glue, based on water-soluble phenolformaldehyde resin SFZh-3014, providing increase of physical-mechanical properties of chipboard with insignificant change of technological process.
