Preparation of Phenol-Formaldehyde-Based Glue and its Use

Abstract

The thermodynamic properties of adhesive compositions based on phenol-formaldehyde resin with modification with furfural acetone monomer FA at the stage of mixing the components. Physical and mechanical properties are presented particle boards based on a modified adhesive composition and technological features of production. Determined that

The best physical and mechanical properties of particle boards are achieved by introducing 2–4 wt.% into phenol-formaldehyde resin, furfural acetone monomer FA, which increases strength, reduces swelling, water absorption, and weight loss of slabs during burning. Wood boards based on modified phenol-formaldehyde resin according to physical and mechanical characteristics meet the requirements of GOST 10632–2018 “Wood-based particle boards. Technical specifications" are superior to analogues based on phenol-formaldehyde resins. With minor costs for modifying the adhesive composition and minor changes technological process increases the competitiveness of the slabs.
