INCREASE OF ADHESION OF PAINT-AND-LACQUER MATERIALS TO WOOD THROUGH THE MODIFICATION OF ITS SURFACE BY BORON-NITROGEN COMPOUNDS
Pages 141 - 146
The authors demonstrate that the efficiency of protection of wooden structures, covered with paints and lacquer materials, from the influence of the environment, depends on the adhesion size.
It is common knowledge that improvement of adhesion of capillary-porous materials to the wood, and, hence, the increase of the service life of the sheeting requires the reduction in the dimensions of the wood surface, as the reduction of diameters of capillaries leads to the growth of forces of capillary condensation and to the increase in the depth of penetration of paints into the material.
Adhesion of a water-soluble acrylic paint and organic-soluble enamels to the surface of the wood modified by boron-nitrogen compounds and to unmodified wood is the subject of the research. It is identified that the increase in the adhesive durability of paint and varnish coverings if glued to the surface of the wood modified by boron-nitrogen compounds, is driven by the growth of the polarity of a substrate and the reduction of dimensions of the wood surface.
