Abstract

The polyol was synthesized from soybean oil. Soybean oil was epoxized with peracetic acid, and was reacted with methanol in a sulfuric acid catalyst. OH value of synthesized polyol was 186(mg KOH/g). The polyurethane foam was synthesized with silicon type B-8409 as a surfactant, distilled water as a blowing agent, dimethylcyclohexylamine as a catalyst, and polymeric MDI. The density, the compressive strength, the compressive modulus, and the cell structure of the synthesized foam were investigated. The foam was prepared with changing the mole ratio of MDI, and the amount of water, surfactant, and catalyst. As the MDI index was increased, the density and the compressive property of the foam were increased.
