Document Type and Number:
Japanese Patent JP3302902
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a deodorizing resin composition that can be formed into packing materials and interior materials, capable of simultaneously removing general odorous components and odor of tobacco smoke, by blending a specific deodorizing component in a thermoplastic resin.
SOLUTION: This composition comprises (A) 100 pts.wt. of a thermoplastic resin, which is formed into plastic films, sheets, containers, fibers or the like; (B) approximately 0.5 to 50 pts.wt. of a deodorizing component, comprising (i) a zinc compound (e.g. zinc oxide), (ii) a sulfate of aluminum (e.g. aluminum sulfate or aluminum potassium sulfate) and (iii) hydrated silica (SiO2.nH2O); as required (C) a metal oxide which can be easily converted into the corresponding metal hydroxide (e.g. calcium oxide); and as required (D) an additive, e.g. coloring agent, filler, loading pigment, plasticizer, stabilizer or ultraviolet ray absorber. It is preferable to use 10 to 50 pts.wt. of the component (i) and 20 to 150 pts.wt. of the component (iii) per 100 pts.wt. of the component (ii).
