The study of interaction between rubber seed oil and epoxy resin

Abstract

Plant oils are regarded as relatively cheap renewable and sustainable raw materials that could be efficiently used for manufacturing of glues, coatings, flooring and other materials. Among the plant oils, rubber seed oil (RSO) is of particular interest as it contains the large amount of free fatty acids. development of new innovative cost-effective technologies for processing renewable agricultural products of plant origin is of acute practical importance as they are considered as advanced sustainable raw materials for manufacturing the products of “green” chemistry. According to the literature review, free fatty acids could enhance performance of polymer composite materials, in particular, on the base of epoxy polymers. Having applied the methods of infrared spectroscopy and titrimetry, the authors identified the absence of chemical interaction between epoxy resin and rubber seed oil at room temperature. Having used the data of differential scanning calorimetry, it was stated that epoxy resins react with rubber seed oil at elevated temperatures.
