microcrystalline cellulose : MCC Polyurethane of increased of biomass-content as well as improvement of material property by filling or reacting modified-microcrystalline cellulose and preparation methods thereof

摘要

TECHNICAL FIELD The present invention relates to a polyurethane having improved physical properties and increased bio content by being charged or bonded with modified microcrystalline cellulose (MCC) and a method for producing the polyurethane. More specifically, the present invention relates to a micro- The present invention relates to a process for preparing polyurethanes and polyurethanes in which microcrystalline cellulose (MCC) is bound, coated, reacted, polymerized or filled. The polyurethanes of the present invention have the advantage that the tensile strength, the yield strength and the biomass content are simultaneously improved, and the compatibility of the surface-modified microcrystalline cellulose and the polyurethane increases. In addition, the polyurethane of the present invention has a high biomass content, which suppresses the use of petroleum, and has an advantage of reducing carbon dioxide emissions.
