POLY-OXYMETHYLENE RESIN COMPOSITION HAVING EXCELLENT FUNCTIONAL PROPERTIES WHILE MINIMIZING THE EMISSION AMOUNT OF VOLATILE ORGANIC COMPOUNDS AND FORMALDEHYDE

摘要

PURPOSE: A poly-oxymethylene resin composition is provided to obtain an environmental-friendly material which is harmless to the human body while maintaining properties and molding processability of the polyoxymethylene resin.;CONSTITUTION: A poly-oxymethylene resin composition comprises, based on 100 parts by weight of a polyoxymethylene resin, 0.01-0.2 parts by weight of a porous organic/inorganic hybrid silica compound and 0.01-3 parts by weight of a hydrazide-based compound. The polyoxymethylene resin has the average molecular weight of 100-1,000,000. The porous organic/inorganic hybrid silica compound has a pore size of 50 nm or less and a surface area of 200-2000 m^2/g. The hydrazide-based compound comprises the compound of chemical formula 3. In chemical formula 3, R is C1-20 alkyl and n is an integer of 1-30.;COPYRIGHT KIPO 2012
