Abstract
The hybrid isocyanate-free polyurethane/epoxy foams were obtained by reaction of carbonized soybean oil and epoxies with diamines. The first stage involves the synthesis of carbonized soybean oil, which was carried out by reaction of carbon dioxide with epoxidised oil in the presence of tetrabutylammonium bromide (TBABr) as a catalyst. At the next stage, hydroxyurethane pre-polymers were obtained by aminolysis of cyclic carbonate of soybean oil with diamines such as aminoethylpiperazine (AEP) and isophorone diamine (IFDA). The adjusting of the molar ratio of IFDA, AEP, compared to carbonized vegetable oil was carried out for receiving pre-polymers with structure and physical properties, which are optimal for further reaction(s). At the last third stage, hybrid NIPU/Epoxy foams were synthesized from hydroxyurethane prepolymer and epoxy resin, in presence of polymethylhydrosiloxane (PMHS) as a reactive foaming agent. The final hybrid NIPU/Epoxy foams were obtained by curing at 80 ◦C during 14 hours. The synthesized foams were investigated by FTIR and DSC, TGA analysis.
