Epoxy Composites Based on Diphenylolmethane Diglycidyl Ethers
Abstract: The main physicochemical properties of diglycidyl esters based on isomers constituting the initial diphenylol methane are characterized. At different ratios of the initial isomers of diphenylol methane with epichlorohydrin, resins with different content of epoxy groups were synthesized. The dependence of the deformation-strength and adhesive properties of polymers on the concentration of epoxy groups in the resin, the chemical nature of the hardener and the temperature-time curing mode is established. It has been found out a high level of tensile strength, deformation at break and the work of the destruction of epoxy composites, especially at low temperatures. In magnitude of impact resistance at low temperatures, composites based on bisphenol F are significantly superior to materials based on widely used deane resin.
Keywords: diglycidyl ethers of bisphenol F, epoxy resin, hardener, gel formation time, glass transition temperature, deformation and strength, adhesion properties.
