METHOD FOR MANUFACTURING EMBEDDED MATERIALS FOR AUTOMOBILES WHICH CAN PREVENT NOISE OF AUTOMOBILES AND ENSURE EXCELLENT INSULATION PROPERTIES USING A SPRAY CONSTRUCTION METHOD OR A MOLD

摘要

PURPOSE: A method for manufacturing embedded materials for automobiles is provided to produce embedded materials through a simple process and to reduce production costs by directly polyurethanes to vehicles using a spray method.;CONSTITUTION: A method for manufacturing embedded materials for automobiles comprises the steps of: (S110) producing a first polyurethane by adding a hardener and a blowing agent to a polyurethane; (S130) blowing the first polyurethane to a vehicle using a first polyurethane; and (S150) blowing a polyurethane coating agent on the dried first polyurethane using a spray method. When the material of polyurethane is soft, the hardener is added in the amount of 20-70 %. When the material of polyurethane is hard, the hardener is added in the amount of 70-200 %. When the material of polyurethane is semihard, the hardener is added in the amount of 20-150%.;COPYRIGHT KIPO 2012
