Abstract:
Wood can be liquefied and used as a feedstock for production of different polymer materials, such as polyesters, polyurethanes and adhesives. The aim of our research was to evaluate the utilization of liquefied wood as an adhesive in a single-layer and a three-layer particleboard production. We also determined gel times for the mixtures of liquefied wood and melamine-formaldehyde or melamine-urea-formaldehyde resin. Results showed that gel time increased with liquefied wood loading and decreased with temperature and addition of catalyst for both types of resins used. Gel times were shorter for melamine-formaldehyde mixtures. Physical and mechanical properties of particleboards with adhesive where 50% of liquefied wood was added met the European standard requirements. Properties were better for three-layer particleboards and when melamine-formaldehyde resin was used. The utilization of liquefied wood in particleboard production gives a new aspect in renewable resources usage and at the same time reduces the crude oil consumption.
