Development of Radiation curable surface coating based on soybean oil. Preparation and characterization of acrylated oil. Part I.

摘要

An epoxy acrylate was synthesized from epoxidized soybean oil (ES-OLj by using acrylic acid monomer. Triethylamine (TEA) and hydro-quinone were used as catalyst and inhibitor respectively. The epoxidized soybean oil acrylate (ESOLA) is done by introducing acrylic acid into oxirane groups of the epoxidized oil (ESOL). This reaction was confirmed by analytical data in terms of oxirane oxygen content, acid value, viscosity and spectroscopically analysis. This acrylated resin can be cured by UV or EB sources by using difunc-tional acrylate monomer as corroslinkable. The mechanical properties of the cured films were measured. Therefore, the optimum irradiation dose by electron beam is 50 kGy and the suitable irradiation time by UV is 30 min. to produce the excellent curing coating. Keywords: acrylation process, soybean oil, coating, radiation.
