Abstract
A resin composition having excellent dispersibility, discoloration resistance and antimicrobial properties by blending a resin (A) with an antimicrobial agent (B) in which at least one kind of metal ion selected from the group consisting of silver, copper, zinc and tin is supported on zeolite, and an antimicrobial agent (C) that includes a silver ion-containing phosphate as an active ingredient, or an antimicrobial agent (D) made of a soluble glass powder containing silver ion.
Claims7
An antimicrobial resin composition, wherein the composition comprises:
- 100 parts by weight of a resin (A),
- 0.01 to 10 parts by weight of an antimicrobial agent (B) which is a zeolite carrying at least one metal ion selected from the group consisting of silver, copper, zinc and tin, and
- 0.01 to 10 parts by weight of an antimicrobial agent (D) which is a soluble glass powder containing silver ion, and
- wherein the average particle diameter of the antimicrobial agent (B) is 0.2 to 10 μm and the average particle diameter of the antimicrobial agent (D) is 0.3 to 10 μm.
An antimicrobial resin composition which exhibits discoloration resistance,
- wherein the composition is a blend of a resin (A), an antimicrobial agent (B) and an antimicrobial agent (D),
- wherein the antimicrobial agent (B) is a zeolite carrying at least one metal ion selected from the group consisting of silver, copper, zinc and tin;
- wherein the antimicrobial agent (D) is a soluble glass powder which contains silver ion;
- and
- wherein the average particle diameter of the antimicrobial agent (B) is 0.2 to 10 μm and the average particle diameter of the antimicrobial agent (D) is 0.3 to 10 μm.
