A Modified Glue for Producing Particle Boards and Boards Based on Waste of Annual Plants

摘要

This paper proposes a water-soluble phenol-formaldehyde resin modified by an alkyd oligomer for reducing the surface tension of an adhesive composition and improving its distribution over wood particles or particles of annual plants during the production of compressed board materials for construction purposes. It was found that the physical and mechanical characteristics of boards increase when produced with the use of the modified glue obtained with a small change in its production technology.
