Abstract: | Beech wood was impregnated with two hot melting waxes. Contact angle measurement followed to determine hydrophobizing of such treated wood. Tensile shear tests were carried out to test the adhesion properties with three different glues under varying environmental conditions. Furthermore, wax impregnated beech was subjected to plasma treatment prior to glueing. The results demonstrate that wood treated with polar paraffin shows lower adhesion properties compared to montan wax. Therefore, montan wax was investigated more intensely. Beech impregnated with such wax can be used for constructive building elements in the interior sector. D3 Glues for non-constructive applications were realized by using PVAc and phenol-resorcinol resin under permanent influence of humidity. Plasma treatment improves this quality to obtain D4 glue. Back-drying of the water stored specimens proves the suitability of isocyanate glue and also that of PVAc after plasma treatment for 120 s. |
