Sažetak
Wood composites are materials of future, and with their wide spectra of potential applications occupy almost all fields of usage. In group of wood composite materials from fragmented wood, "valueless" biomass and residues after usage are converted to valuable material. The problem with application of other necessary synthetic chemical components (particularly adhesives), mainly oil derivatives, which according to oil shortage and price growth on world market can endanger that production, has been the subject of many scientific researches which gave positive results. The above mentioned adhesives are essential non-wooden components in wood composite production. Linked to above, many researches are focused on wood liquefaction and liquefied wood (LW) application as potential adhesives, apropos to gluing solid particles with liquid wood. Based on previous studies, maximum attention was given to LW applications in modification of phenol-formaldehyde (PF) resins, polyurethanes, saturated and unsaturated polyesters, isocyanates and epoxy resins, and their further application in novel material types. It is evident that because of their "inferior" properties, researches on urea-formaldehyde (UF) resins failed, as well as researches on preparations of adhesives on UF base modified with LW. Therefore, the subject of this study was researching the influence of specific pressing parameters on liquefied wood compatibility with UF resins, its influence on polymer structure and adhesion-cohesion properties of modified UF adhesives, and particleboards physical-mechanical properties and formaldehyde emission.
