LNG Rigid Polyurethane Foams for LNG Ship-Insulator Containing Biopolyol

摘要

The present invention relates to a rigid polyurethane foam for LNG carrier insulation containing a bio polyol, and more particularly, contains a natural oil, a polyfunctional active hydrogen-containing compound, a catalyst and an alkylene oxide, having 3 or more functional groups, KOH / g having a hydroxyl value of 200 to 600 mg and containing a polyol containing a bio polyol having a viscosity (25 ° C.) of 2,000 to 25,000 cps, excellent compressive strength, normal and low temperature tensile strength, thermal conductivity, The present invention relates to a rigid polyurethane foam for LNG insulation, which can maintain physical properties for insulation of LNG carriers, such as impregnation and impact resistance, and is environmentally friendly and renewable.
