Abstract
Unmodified castor oil (CO) was used to obtain a castor-based aqueous polyurethane (CPUD) and isophorone diisocyanate (IPDI) was used to obtain a transparent film. The mixing effect of polypropyleneglycole (PPG) was analyzed to increase flexibility. In addition, ethylenediamine (EDA) was used as a chain extender. Tensile strength, elongation, and abrasion resistance were measured according to the change according to the castor oil content and the change in the chain extender, respectively. The tensile strength of the sample containing a lot of castor oil was 1.112 kgf/㎟, and the elongation was 88%. The tensile strength of the sample containing a lot of chain extender was 3.33kgf/㎟, and the elongation was 99%. The surface strength was visually confirmed through SEM. The surface strength was visually confirmed through SEM.
