epoxide

The work investigated the influence of the nature of the binder and filler modifier on the rheological properties of epoxy composites based on ED-20 resin. The binder was modified by introducing epoxidized soybean oil and a mixture of polyvinyl butyral with epoxidized soybean oil. Copper polyvinyl chloride, and aluminum oxide, as well as their mixture, were used as fillers. It was found that filling and modification of the matrix change the nature of the flow curves. The resulting composites are characterized by a uniform distribution of the filler. 

The article is presenting a modification of bituminous binder with ecological epoxidized rapeseed oil (BERO) in the presence of the initiator (hardener). Adipic acid (AA), maleic anhydride (MA) and polyethylene polyamine (PEPA) were used as the initiators. The effect of modification temperature and, as well as initiator nature, on the bitumen properties was determined. Bitumen modified with BERO was evaluated by the following indicators: softening temperature, penetration, ductility, and adhesion to the glass.

The investigation results of type B fine asphalt concrete and its form modified by rapeseed oil epoxide are represented. The efficiency of ERO addition and its positive effect on the physico-mechanical properties of asphalt concrete has been established.

The use of IR-spectroscopy has been proposed to determine the content of hydroxy groups in the modified functional oligomers based on bisphenol A diglycidyl ether. Apart from hydroxy groups the investigated oligomers contain epoxy or peroxy, carboxy or acrylic groups.
