This paper discusses the development of a modified, environmentally safe adhesive based on liquid glass (sodium silicate Na₂O·nSiO₂) with enhanced adhesion efficiency to wood. The sodium silicate used fully complies with the requirements of GOST 13078–81 and TU 6-18-003-87, with a silicate modulus of 2.6–2.8 and a solid residue content of 31–33%. An oligomer based on thiourea and glycerol was used as a modifier. The experiments were carried out by mixing the modifier with liquid glass in various mass ratios (5%, 10%, 15%). The experimental results showed that the modification process significantly improved the rheological and mechanical properties of the adhesive. At the optimal 10% modifier content, the adhesion strength increased from 2.28 MPa to 3.15 MPa (an increase of 27.6%), while water resistance rose from 62% to 82%. The viscosity was approximately 230 mPa·s, which fully meets the industrial range specified in GOST 13078–81 (200–250 mPa·s). The resulting modified adhesive does not release formaldehyde, is non-toxic, and environmentally safe, providing high adhesion and water resistance for wood bonding. The obtained results form a scientific and practical basis for expanding the use of modified sodium silicate-based adhesives in woodworking, construction, and furniture industries.
