METHOD FOR PREPARING A NITRILE-BASED RUBBER CAPABLE OF MINIMIZING MOLD CONTAMINATION IN THE MOLDING OF A NITRILE RUBBER USING FATTY ACID EMULSIFIER AND SYNTHETIC OIL

摘要

PURPOSE: A method for preparing a nitrile-based rubber is provided to prevent foreign materials in the mold in an injection molding process and to ensure fast polymerization rate. ;CONSTITUTION: A method for preparing a nitrile-based rubber comprises a step of adding 1.5~2 parts by weight of C14~18 aliphatic organic acids and 0.1~0.5 parts by weight of synthetic emulsifier based on 100.0 parts by weight of a monomer constituting the nitrile-based rubber. The C14~18 aliphatic organic acid is selected from lauric acid, myristic acid, oleic acid, palmitic acid, stearic acid, and eicosanoic acid.;COPYRIGHT KIPO 2011
