In a new work, epoxy formulations containing phenolic resins, recycled tire powder and clay nanochikes are optimized based on the L9 Taguchi experimental design method.
phenolic resin (X1 (wt. % for thermal stability), recycled tire powder (X2 (wt
). %) and is economically suitable for toughening) and clay nanofiles (X3 (wt). %, the main role used to improve the mod by taking into account signal-to-noise ratio (S/N) and variance analysis (ANOVA) to study the mechanical properties of epoxy adhesives, including stretch strength, Yang's mod and toughness.
Improved thermal stability
has been found to have observed a one-turn shear strength increase of approximately 39% compared to blank epoxy adhesive preparations, with x1 levels of 50 weights, X2 levels of 10 weight% and X3 levels of 2 weights. A scanning electron microscope reveals the cracking pattern in which the crack expansion path deviates from the form when encountering large plate-like nano clay. According to the degradation peak temperature monitoring, the thermal stability of epoxy resin was also increased by 16%.
the study was published in Organic Coatings Progress Volume 136, November 2019, 105291.
