Epoxy Materials Hardened with the Solvolysis Product from Waste Poly(ethylene terephthalate) PET
In this work epoxy materials (composites and adhesives) hardened with curing systems: imidazole derivative (as catalytic hardener) with-various contents of PET/triethanolamine (TEA) chemical degradation product have been investigated. As epoxy resin Epidian 6 (bisphenol A type) was used. The applied imidazole derivatives Were the following: 2-methylimidazole – 2M, 2-ethyl-4-methylimidazole – 2E4M or 1-allyl-2-methylimidazole – TL, all products of Sigma-Aldrich. Imidazole component was introduced in amount I g together with 5, 10 or 15 g PET/TEA per 100 g of epoxy resin. The mechanical properties of the epoxy composites and adhesive joints on aluminum substrates have been investigated at room temperature. For comparison epoxy systems hardened with only imidazole derivates were evaluated as well. The investigations and analysis of results allowed to draw up the following conclusions: (i) epoxy composites hardened in a presence of degradation product PET/TEA exhibit usually higher bending strength and lower Young’s modulus and modulus of elasticity than only imidazole derivative cured materials, (ii) the highest shear strength values offer epoxy adhesives hardened with TL imidazole in a presence of PET/TEA product.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 616-47-7, you can contact me at any time and look forward to more communication. HPLC of Formula: C4H6N2.
