POLYURETHANE POLYURE COMPASITE RADIATED WITH INFRARED RAYS AND A NEGATIVE ION

摘要

PURPOSE: A polyurethane polyurea resin composition is provided to prevent from discharging environmental hormone by not including solvents. CONSTITUTION: A polyurethanes polyurea resin composition includes a mixture of polyisocyanate prepolymer and polyamine in a equivalence ratio of 0.95-1.15. The polyurethanes polyurea resin composition comprises 2-73 wt% of aromatic modified methylene diphenyl diisocyanate, 2-73 wt% of aromatics monomeric methylene diphenyl diisocyanate, and 25-65 wt% of polyether polyol. The polyamine mixture comprises 4-20 wt% of polyether amine, 10-63 wt% of polyester amine with molecular weight of 2000, 22-27 wt% of 10~63 wt% of chain extender with a molecular weight of 178.3, 4-6 wt% of pigment, 0.5-1.5 wt% of UV absorber, 1-20 wt% of far infrared rays and anion emission material, and 1-2 wt% of dispersant additive synthesized material.
