“…The available literature provides information about the methods for modifying adhesive compounds [1,2,3,4,5,6] to obtain specific properties [7,8,9,10,11,12] and improve their adhesive properties (which are vital for producing adhesive joints) [7], e.g., by the addition of different modifiers such as nanofillers [13,14,15,16] and lignin fillers [17,18,19,20,21,22,23,24,25,26]. Ghaffar and Fan [17] provided an overview of the problem, focusing on the chemical structure and composition of lignin in straw as well as the modification and application thereof as an adhesive.…”

Abstract:The main objective of this study was to determine the effect of biochemical modification of epoxy adhesive compounds on the mechanical properties of a cured adhesive exposed to various climatic factors. The epoxy adhesive was modified by lyophilized fungal metabolites and prepared by three methods. Additionally, the adhesive compound specimens were seasoned for two months at a temperature of 50 • C and 50% humidity in a climate test chamber, Espec SH 661. The tensile strength tests of the adhesive compounds were performed using a Zwick/Roell Z150 testing machine in compliance with the DIN EN ISO 527-1 standard. The examination of the adhesive specimens was performed using two microscopes: a LEO 912AB transmission electron microscope equipped with Quantax 200 for EDS X-ray spectroscopy and a Zeiss 510 META confocal microscope coupled to an AxioVert 200M. The experiments involved the use of a CT Skyscan 1172 tomograph. The results revealed that some mechanical properties of the modified adhesives were significantly affected by both the method of preparation of the adhesive compound and the content of the modifying agent. In addition, it was found that seasoning of the modified adhesives does not lead to a decrease in some of their mechanical properties.
